Kinds of Surgery Procedures Selected AbstractsDexamethasone decreases oxycodone consumption following osteotomy of the first metatarsal bone: a randomized controlled trial in day surgeryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2010K. MATTILA Background: Dexamethasone may improve multimodal pain management following painful orthopedic day surgery procedures, and decrease the need for post-operative opioids. We hypothesized that dexamethasone would reduce the need for oxycodone after surgical correction of hallux valgus. Methods: Sixty patients planned to undergo unilateral osteotomy of the first metatarsal as a day surgery procedure were randomized to receive pre-operatively and 24 h afterwards, orally either dexamethasone 9 mg or placebo. For pain medication, paracetamol and oxycodone capsules for rescue medication were given. The study ended on the evening of the third post-operative day (POD). The primary endpoint was the cumulative oxycodone consumption. Secondary endpoints were maximal pain scores before oxycodone intake and daily oxycodone doses. In addition, adverse effects were documented. Results: Twenty-five patients in both groups completed the study. The total median (range) oxycodone consumption during the study period was 45 (0,165) mg in the dexamethasone group and 78 (15,175) mg in the placebo group (P=0.049). The major differences in oxycodone consumption were seen on PODs 0,1. In the dexamethasone group, patients reported significantly lower pain scores on PODs 0,1, and significantly less nausea on POD 1. On PODs 2,3 no differences were seen. However, at 2 weeks post-operatively, patient satisfaction to drug therapy did not differ , in both groups 81% would have chosen the same medication again. Conclusion: Oral dexamethasone combined with paracetamol significantly reduced total oxycodone consumption following surgical correction of hallux valgus. [source] Single Implants and Buccal Bone Grafts in the Anterior Maxilla: Measurements of Buccal Crestal Contours in a 6-Year Prospective Clinical StudyCLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 3 2005Odont Dr/PhD, Torsten Jemt DDS ABSTRACT Background: Patients provided with buccal bone grafts seem to lose a substantial part of the graft in the short term. Purpose: To measure long-term changes in buccal and proximal tissue volumes after local bone grafting and single implant treatment. Materials and Methods: Eight of 10 originally treated male patients were followed up for 6 years after treatment with buccal bone grafts in the central incisor region. After a healing time of 6 months, a two-stage implant surgery procedure was performed followed by single crown placement. Clinical photographs and impressions were taken prior to the surgical interventions and after crown placement and at first and fifth annual checkups. The photographs were analyzed with regard to papilla regeneration by means of a clinical papilla index. The models were used to measure the clinical length of teeth and tooth movements adjacent to the implants. Changes in buccal crest volume during the study period were measured by means of optical scanning of obtained study models. Results: Papillae volume increased significantly (p < .05) during the first year, thereafter showing a slow further increase during the 4 following years. Three of the patients (38%) presented small movements of their adjacent central incisor in a vertical or palatal direction of less than 1 mm during the follow-up period. All patients showed resorption during the first year after grafting (p < .01), in which three patients (38%) had lost basically all of increased volume at second surgery. After abutment or crown placement, all patients showed an increased volume (p < .01), followed by an average reduction during the first year, reaching a significant level in the apical part of the crest (p < .05). Thereafter, a relatively stable average situation was observed during the following 4 years, with individual variations, however. Conclusion: Local bone grafting seems to create sufficient bone volume for implant placement after 6 months, but individual variations in resorption pattern make the grafting procedure unpredictable for long-term prognosis. Instead, the abutment and the crown seem to play a more important role for building up and maintaining the buccal contour in the coronal part of the crest long term. [source] Review of the Liposuction, Abdominoplasty, and Face-Lift Mortality and Morbidity Risk LiteratureDERMATOLOGIC SURGERY, Issue 7 2005Robert A. Yoho MD Background The statistical discrepancies that exist in the mortality and morbidity risk literature are such that surgeons and patients cannot accurately assess the true risk rates associated with plastic surgery procedures. Objectives and Methods To review any relevant literature published to date in which the risk rates from liposuction, abdominoplasty, and rhytidectomy are cited and to reassess these figures alongside those published for both elective and emergency general surgeries. Results and Conclusion Despite the lack of reliable, comprehensive reporting of deaths and complications resulting from cosmetic surgeries, published data demonstrate that the risks associated with liposuction and rhytidectomy compare favorably with those from most general surgical procedures. In contrast, the morbidity and mortality rates from abdominoplasty remain unacceptably high. A significant lack of literature documenting cosmetic breast implant surgery and blepharoplasty risks is observed, which should be of concern to both patients and physicians. Liposuction and face-lift surgery data generally show that surgical centers are statistically safer than hospital operating rooms, although the data have not been standardized for the patients' American Society of Anesthesiologists (ASA) risk class, the health of the patient prior to surgery. General anesthesia may carry a risk roughly equivalent to or perhaps greater than cosmetic surgery, although, again, ASA class variables confound clear comparison between studies. Recent anesthesia literature refutes the many claims that general anesthesia risks are now remote: a landmark study that surveyed the entire scholarly literature showed a mortality rate of 1 in 13,000, roughly similar to overall cosmetic surgery mortality risks. Moreover, a prolonged operating time has been repeatedly implicated in other surgical literature to be related to morbidity and mortality. The latter certainly has relevance to cosmetic surgery. [source] No Smoking Gun: Findings From a National Survey of Office-Based Cosmetic Surgery Adverse Event ReportingDERMATOLOGIC SURGERY, Issue 11 2003Rajesh Balkrishnan PhD Background. Because of recent press reports of adverse outcomes, office-based cosmetic surgery has come under intense scrutiny and associated legislative regulatory action. Objective. To assess the safety of office-based cosmetic surgery through a national survey of state agencies that collect information on adverse patient outcomes. Methods. Medical boards or other responsible authorities were contacted in 48 states to obtain records on adverse outcomes from cosmetic surgery procedures performed in an office-based setting. Results. Five states were able to provide complete information regarding 13 cases of adverse outcomes that resulted from office-based cosmetic surgery procedures. Thirteen states had incomplete information or were unable to provide information. The remaining states reported no adverse outcomes. Information collected by state agencies varies greatly and is inadequate to define the safety of office-based cosmetic surgery practice. Conclusions. The need to regulate physician office surgery on the basis of hospital privileges and office certification is not supported by current data. Mandatory reporting of adverse outcomes from office-based surgery is warranted to identify modifiable risk factors and to reduce the risk of adverse outcomes. [source] Beauty Versus Medicine: The Nonphysician Practice of Dermatologic SurgeryDERMATOLOGIC SURGERY, Issue 4 2003Harold J. Brody MD Background This investigation was initiated because of a growing concern by the American Society for Dermatologic Surgery about the proliferation of nonphysicians practicing medicine and its impact on public health, safety, and welfare. Objective Prompted by an alarming rise in anecdotal reports among dermatologic surgeons, the study sought to determine whether there was a significant increase in the number of patients seeking corrective treatment due to complications from laser and light-based hair removal, subsurface laser/light rejuvenation techniques, chemical peels, microdermabrasion, injectables, and other cosmetic medical/surgical procedures performed by nonphysicians without adequate training or supervision. Methods A survey of 2,400 American Society for Dermatologic Surgery members in July 2001 and in-depth phone interviews with eight patients who experienced complications from nonphysicians performing cosmetic dermatologic surgery procedures were conducted. Results Survey data and qualitative research results attributed patient complications primarily to "nonphysician operators" such as cosmetic technicians, estheticians, and employees of medical/dental professionals who performed various invasive medical procedures outside of their scope of training or with inadequate or no physician supervision. Conclusion The results underscore the need for improved awareness, legislation, and enforcement regarding the nonphysician practice of medicine, along with further study of this issue. [source] Efficacy, Safety, and Cost of Office-Based Surgery: A Multidisciplinary PerspectiveDERMATOLOGIC SURGERY, Issue 1 2003Rajesh Balkrishnan PhD An increasing number of media reports on patient safety risks arising from office-based surgery procedures, as well as growing concerns about patient safety issues in general, have brought office-based surgery as well as its practitioners into focus and placed this very cost-effective medical practice in the eye of the media and regulators. Concerted efforts are now being made to understand the causes and true incidence of patient safety risk associated with office-based surgery and to find ways to minimize this risk. [source] Bariatric surgery vs. advanced practice medical management in the treatment of type 2 diabetes mellitus: rationale and design of the Surgical Therapy And Medications Potentially Eradicate Diabetes Efficiently trial (STAMPEDE)DIABETES OBESITY & METABOLISM, Issue 5 2010Sangeeta R. Kashyap Obesity and Type 2 diabetes mellitus (T2DM) are closely interrelated, and are two of the most common chronic, debilitating diseases worldwide. Surgical approaches to weight loss (bariatric surgery) result in marked improvement of T2DM, however randomized trials directly comparing the efficacy of surgical and medical approaches are lacking. The Surgical Therapy and Medications Potentially Eradicate Diabetes Efficiently (STAMPEDE) trial was designed to evaluate the efficacy of two bariatric surgery procedures involving gastric restriction only (laparascopic sleeve gastrectomy) and gastric bypass (Roux-en-Y) to advanced medical therapy in patients with T2DM with modest obesity with BMI of 27,42 kg/m2. This single site, prospective, randomized controlled trial will enroll 150 subjects who will be followed. The primary end point will be the rate of biochemical resolution of T2DM at 1 year as measured by HbA1c < 6%. The safety and adverse event rates will also be compared between the three arms of the study. [source] Assessing competency in Dentoalveolar surgery: a 3-year study of cumulative experience in the undergraduate curriculumEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 4 2007J. A. Durham Aim:, To assess and observe the development of competence in oral surgical skills during a 3-year undergraduate programme. Method:, Over a 3-year period 75 students were followed through from the beginning of their clinical course to their Bachelor of Dental Surgery graduation and their surgical experience monitored by the use of logbooks. Their development of competence was assessed objectively through structured assessments and subjectively by a single tutor responsible for each year. Assessments were made of their ability in exodontia, pre-surgical assessment and the surgical extraction of teeth/roots. Results:, Seventy-three students completed the course (97%). Successful completion rates for the objective testing were 100% for both exodontia and pre-surgical assessment. The surgical assessment, (surgical extraction of a tooth or root) had a successful completion rate of only 23% and the caseload for students was low with a mean of four teeth removed surgically upon graduation. Relationships were examined between total numbers of teeth extracted, total number of minor oral surgical procedures completed and the successful completion of the surgical competence assessment, but no significant relationships were found. Conclusions:, This study demonstrates that it is possible to achieve objectively measurable levels of competence in undergraduates undertaking oral surgery procedures. It is however, a labour and time intensive process and appropriate clinical and teaching resources are required. National co-operation towards agreed standardised competencies should be encouraged to allow data to be pooled and more powerful analyses to occur. [source] Dental procedures in adult patients with hereditary bleeding disorders: 10 years experience in three Italian Hemophilia CentersHAEMOPHILIA, Issue 5 2005M. Franchini Summary., Excessive bleeding after dental procedures are one of the most frequent complications occurring in patients with hereditary bleeding disorders. In this retrospective study we collected data from 10 years of experience in the oral care of patients with congenital haemorrhagic disorders in three Italian Hemophilia Centers. Between 1993 and 2003, 247 patients with inherited bleeding disorders underwent 534 dental procedures including 133 periodontal treatments, 41 conservative dentistry procedures, 72 endodontic treatments and 288 oral surgery procedures. We recorded 10 bleeding complications (1.9%), most of which occurred in patients with severe/moderate haemophilia A undergoing multiple dental extractions. Thus, our protocol of management of patients with hereditary bleeding tendency undergoing oral treatment or surgery has been shown to be effective in preventing haemorrhagic complications. [source] How to use laparoscopic surgical instruments safelyINTERNATIONAL JOURNAL OF UROLOGY, Issue 3 2009Eiji Higashihara The development of laparoscopic surgery has been accompanied by a rapid increase in the number of laparoscopic surgical procedures carried out in the field of urology. In 2002 laparoscopic nephrectomy was approved for coverage under Japanese national health insurance, and in 2003 there were over 1000 registered cases in which this procedure was carried out. This suggests that laparoscopic nephrectomy, a procedure formerly conducted at only a few institutions, is now spreading to hospitals across Japan. Laparoscopic surgery involves the use of specialized instruments within a restricted field of vision, and risky surgical techniques can potentially result in visceral or vascular damage. In order to promote the use of safe laparoscopic surgery procedures, the Japanese Urological Association and the Japanese Society of Endourology and Extracorporeal Shock Wave Lithotripsy (ESWL) have inaugurated a certification program for urologic laparoscopy. This program not only encourages development in this field of surgery and provides technical certification to ensure appropriate levels of expertise, but also reviews methods for the correct use of instruments such as trocars and hemostats. The purpose of this video is to present correct methods for the use of a variety of laparoscopic instruments, in order to increase the safety of this procedure. The video has been designed to be useful not only for practitioners who are just beginning laparoscopy, but also for those who already have extensive laparoscopic experience. The video discusses five laparoscopic instruments (trocar, electric surgical devices, ultrasonic surgery devices, clips and clip appliers and endo-staplers), and demonstrates their correct use. In addition, animal models are used to illustrate the potential complications that can be associated with some methods of use.

[source] Ineffectiveness of Local Wound Anesthesia to Reduce Postoperative Pain After Median SternotomyJOURNAL OF CARDIAC SURGERY, Issue 4 2005Diego Magnano M.D. Bupivacaine wound infiltration is frequently used to reduce the pain related to the surgical incision itself. In this randomized study, we investigated the efficacy of bupivacaine local anesthesia after median sternotomy to reduce postoperative pain. Forty-seven patients undergoing major cardiac surgery procedures were allocated randomly to group A (bupivacaine wound infiltration 0.5%; 10 mL, followed by continuous infusion: 10 mg/24 H) or to group C (controls). Extubation time, postoperative arterial blood gases, postoperative pain (assessed by means of a visual analog scale), and morphine consumption were the endpoints of the study. Patients of group C were extubated earlier; blood gases and VAS values were similar in both group. Bupivacaine local analgesia did not improve postoperative pain control after median sternotomy. [source] Transvenous Cardioverter-Defibrillator Implantation in a Patient with Tricuspid Mechanical ProsthesisJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 3 2007MAURO BIFFI M.D. Background. A 64-year-old woman was referred to our center because of poorly tolerated ventricular tachycardia (VT) at 210 bpm due to an old myocardial infarction. The patient had been operated on at age of 20 for mitral valve commissurolysis, at age of 49 for ductal carcinoma, at age of 56 for mitral valve replacement, and at age of 61 for tricuspid valve replacement. Left ventricular EF was 31%. The patient was in permanent atrial fibrillation (AF) since the age of 53. She had undergone three cardiac surgery procedures, ending with two prosthetic mechanical valves. The cardiac surgery team advised against an epicardial ICD implantation. Results. We achieved a fully transvenous implant, with a screw-in defibrillation coil in the low right atrium and a bipolar pacing/sensing lead in a posterolateral branch of the coronary sinus. Pacing/sensing parameters were reliable, and effective defibrillation occurred at 20 J by a stepdown protocol. During 16-month follow-up, three VT episodes at 210 bpm were terminated by antitachycardia pacing (ATP) therapy. Left ventricular pacing/sensing was stable at long term. Conclusion. Thanks to technologic improvements, transvenous ICD implantation is feasible and safe in patients with a tricuspid mechanical prosthesis. [source] Waiting for scheduled services in Canada: development of priority-setting scoring systemsJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 1 2003T. W. Noseworthy MD MSc MPH FRCPC FACP FCCP FCCM CHE Abstract Rationale, aims and objectives An Achilles' heel of Canadian Medicare is long waits for elective services. The Western Canada Waiting List (WCWL) project is a collaboration of 19 partner organizations committed to addressing this issue and influencing the way waiting lists are structured and managed. The focus of the WCWL project has been to develop and refine practical tools for prioritizing patients on scheduled waiting lists. Methods Scoring tools for priority setting were developed through extensive clinical input and highly iterative exchange by clinical panels constituted in five clinical areas: cataract surgery; general surgery procedures; hip and knee replacement; magnetic resonance imaging (MRI) scanning, and children's mental health. Several stages of empirical work were conducted to formulate and refine criteria and to assess and improve their reliability and validity. To assess the acceptability and usability of the priority-setting tools and to identify issues pertaining to implementation, key personnel in the seven regional health authorities (RHAs) participated in structured interviews. Public opinion focus groups were conducted in the seven western cities. Results Point-count scoring systems were constructed in each of the clinical areas. Participating clinicians confirmed that the tools offered face validity and that the scoring systems appeared practical for implementation and use in clinical settings. Reliability was strongest for the general surgery and hip and knee criteria, and weakest for the diagnostic MRI criteria. Public opinion focus groups endorsed wholeheartedly the application of point-count priority measures. Regional health authorities were generally supportive, though cautiously optimistic towards implementation. Conclusions While the WCWL project has not ,solved' the problem of waiting lists and times, having a standardized, reliable means of assigning priority for services is an important step towards improved management in Canada and elsewhere. [source] Application of visual tracking for robot-assisted laparoscopic surgeryJOURNAL OF FIELD ROBOTICS (FORMERLY JOURNAL OF ROBOTIC SYSTEMS), Issue 7 2002Xiaoli Zhang With the increasing popularity of laparoscopic surgery, the demand for better modes of laparoscopic surgery also increases. The current laparoscopic surgery mode requires an assistant to hold and manipulate the endoscope through commands from the surgeon. However, during lengthy surgery procedures, accurate and on-time adjustment of the camera cannot be guaranteed due to the fatigue and hand trembling of the camera assistant. This article proposes a practical visual tracking method to achieve automated instrument localization and endoscope maneuvering in robot-assisted laparoscopic surgery. Solutions concerning this approach, such as, endoscope calibration, marker design, distortion correction, and endoscope manipulator design are described in detail. Experimental results are presented to show the feasibility of the proposed method. © 2002 Wiley Periodicals, Inc. [source] No osteonecrosis in jaws of young patients with osteogenesis imperfecta treated with bisphosphonatesJOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 4 2008Barbro Malmgren Background:, Recent reports of osteonecrosis of the jaw (ONJ) after dental surgery in patients treated with second- and third-generation nitrogen-containing bisphosphonates instigated this retrospective study. As treatment with bisphosphonates in patients with osteogenesis imperfecta (OI) has become an important symptomatic therapy, especially for severe forms of the disease, we found it important to investigate whether healing after surgical exposure of jaw bone was influenced by the bisphosponate treatment in our group of children, adolescents and young adults with OI. Subjects and methods:, Disodiumpamidronate was given as monthly intravenous infusion to 64 patients with OI aged 3 months to 20.9 years at the start of treatment (mean 8.1, median 7.7). During 0.5,12.5 years of treatment (mean 4.5, median 4.0), a total individual dose of 140,4020 mg/m2 disodiumpamidronate was given (mean 1623 and median 1460). Ten patients continued with oral alendronate and two with zoledronic acid therapy. In 22 of these patients, 38 dental surgery procedures were performed at the age of 3.4,31.9 years (mean 12.2, median 12.3) after 0.03,7.9 years of treatment (mean 3.6, median 3.4). Results:, Despite long-term intravenous monthly disodiumpamidronate treatment, none of the 64 patients had any clinical signs of ONJ. Conclusions:, The risk of ONJ in these patients must be considered so low that the patients with indications for treatment should be treated and get the chance to experience the well-documented beneficial effect for children with severe OI. [source] Minimally Invasive Vein Surgery: Latest Options for Vein DiseaseMOUNT SINAI JOURNAL OF MEDICINE: A JOURNAL OF PERSONALIZED AND TRANSLATIONAL MEDICINE, Issue 3 2010FACPhArticle first published online: 20 MAY 2010, Steven Elias MD Abstract The goal of treatment for venous disease is to decrease ambulatory venous hypertension. Various strategies are employed. These can be divided into exogenous and endogenous treatments. Exogenous methods concern those employed from the outside of the limb, such as compression and elevation. Endogenous modalities treat from inside the limb the underlying venous pathology due to venous valvular dysfunction or venous obstruction. Traditional endogenous procedures include stripping, ligation, and phlebectomy. All these procedures require incisions, anesthesia, and perhaps hospitalization, and involve significant discomfort. Newer minimally invasive vein surgery procedures now exist. These are all same-day, outpatient procedures, usually involving local anesthesia. Most can be performed percutaneously without incisions. Patients ambulate the day of the procedure. Morbidity is less than 1%. This article summarizes the concept of minimally invasive vein surgery and summarizes new technologies to manage all forms of venous disease.

Woolcombe Abstract Aim:, We aim to determine the prevalence of undiagnosed/poorly controlled hypertension and study the population demographics. We also aim to study the effects of intravenous midazolam on peri-operative blood pressure and pulse. Finally, we aim to assess the value of screening for hypertension and determine the degree of white coat hypertension. Material and methods:, A cohort of 83 patients with a pre-assessment blood pressure recording ,160/100 mmHg was studied. Oral surgery treatment was performed under intravenous sedation with midazolam or local anaesthesia alone where sedation was contraindicated. Blood pressure and pulse were monitored throughout surgery. Following treatment, patients were advised to attend their General Practitioner (GP) for assessment of their blood pressure and information regarding the outcome of this visit was requested. Results:, Seventy-three percent of the cohort had no previous diagnosis of hypertension. The use of intravenous midazolam significantly reduced peri-operative blood pressure compared with local anaesthesia alone [reduction in systolic blood pressure (BP) of 40 mmHg and diastolic BP of 21 mmHg]. Fifty percent of those who attended their GP received active treatment for hypertension at the first visit. A further 25% were kept under review. Blood pressure measurements at hospital pre-assessment were substantially higher than those recorded by GPs. Conclusion:, A clear indication exists for the use of intravenous sedation with midazolam for oral surgery procedures in patients with high blood pressure. There is a significant prevalence of undiagnosed and poorly controlled hypertension. Blood pressure screening in the dental setting is a valuable tool for identifying hypertensive patients. White coat hypertension is significantly greater in the oral surgery department than at the GP surgery. [source] Elective Surgical Patients as Living Organ Donors: A Clinical and Ethical InnovationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2009G. Testa We propose a new model for living organ donation that would invite elective laparoscopic cholecystectomy patients to become volunteer, unrelated living kidney donors. Such donors would be surgical patients first and living donors second, in contrast to the current system, which ,creates' a surgical patient by operating on a healthy individual. Elective surgery patients have accepted the risks of anesthesia and surgery for their own surgical needs but would face additional surgical risks when a donor nephrectomy is combined with their cholecystectomy procedure. Because these two procedures have never been performed together, the precise level of additional risk entailed in such a combined approach is unknown and will require further study. However, considering the large number of elective cholecystectomies performed each year in the United States, if as few as 5% of elective cholecystectomy patients agreed to also serve as living kidney donors, the number of living kidney donors would increase substantially. If this proposal is accepted by a minority of patients and surgeons, and proves safe and effective in a protocol study, it could be applied to other elective abdominal surgery procedures and used to obtain other abdominal donor organs (e.g. liver and intestinal segments) for transplantation. [source] The effect of grade of anaesthetist on outcome after day surgery,ANAESTHESIA, Issue 2 2009J. Hanousek Summary We conducted a retrospective survey to investigate if the grade of anaesthetist was a significant factor in determining outcome after day surgery in a district general hospital. All day surgery procedures performed between 1996 and 2006 were included except those under surgically administered local anaesthetic. The outcome measures assessed were unplanned admissions and symptoms reported after discharge. The overall admission rate was 2.6%, the admission rate for anaesthetic-related reasons was 1.5%, and 49% of patients reported some symptoms after discharge. Over the period studied the admission rate fell from 4.2% to 2.0%, admissions for anaesthetic-related reasons fell from 3.0% to 0.7% and reported symptoms fell from 67% to 37%. Consultants anaesthetists were associated with the lowest unplanned admission rate (consultants 2.3%, staff grade and associate specialists 3.1%, and trainees 3.3%), the lowest admission rate for anaesthetic reasons (consultants 1.2%, staff and associate specialists 2.0%, and trainees 1.8%), lower than expected specialty-weighted admissions and the lowest number of reported symptoms (consultants 47.3%, staff grade and associate specialists 52.6%, trainees 49.0%) (p < 0.001). We conclude that there was an improvement in outcome over the period of study and that the grade of anaesthetist is associated with outcome after day surgery. [source] The benefits and problems associated with minimal access surgeryAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2002Ray Garry ABSTRACT The place of minimal access surgery (MAS) in current gynaecological practice remains controversial. As a consequence, MAS techniques have been subject to a significant amount of prospective, evidence-based assessment. The ultimate results of these comparative trials will undoubtedly have a profound impact on the future direction of our speciality. It is timely, therefore, to review the currently available data. Evidence from 2195 patients in 23 randomised clinical trials of five different treatment modalities (ectopic, ovarian cysts, myomectomy, colposuspension and hysterectomy) clearly demonstrates that uncomplicated MAS procedures produce patient-friendly benefits, at least in the short term. No matter what operation is performed, the laparoscopic approach is associated with less pain, shorter hospital stay and shorter recovery. These immediate patient-orientated benefits are a generic consequence of replacing the manoeuvres of open surgery through laparotomy incisions with minimal access. These benefits must be offset against significant disadvantages. Minimal access surgery procedures always require the use of expensive, high technology equipment and usually take longer to perform. Such procedures may be more costly than current open procedures and costs will, in part, be dependent on the amount of disposable equipment employed. Patients undergoing MAS procedures may be at risk of new and/or increased risk of traditional complications. The longer-term results of most MAS procedures have not yet been determined. These potential benefits and disadvantages of MAS require that each procedure is carefully and individually assessed. This paper seeks to review the current evidence. [source] Clopidogrel: mechanisms of action and review of the evidence relating to use during skin surgery proceduresCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 4 2010L. C. Stewart Summary Patients who have skin surgery may be taking medication that increases the likelihood of bleeding, such as clopidogrel, aspirin, warfarin, heparin and nonsteroidal anti-inflammatory drugs (NSAIDS). All of these may increase the risk of perioperative and postoperative bleeding. This article examines the mechanism of action of clopidogrel, current practice, and evidence for or against continuing its use during skin surgery. The mechanisms of action of aspirin, warfarin, heparin and NSAIDS will also be briefly discussed. [source] What influence do anticoagulants have on oral implant therapy?CLINICAL ORAL IMPLANTS RESEARCH, Issue 2009A systematic review Abstract Objectives: This systematic review aims to assess the risks (both thromboembolic and bleeding) of an oral anticoagulation therapy (OAT) patient undergoing implant therapy and to provide a management protocol to patients under OAT undergoing implant therapy. Material and methods: Medline, Cochrane Data Base of Systematic Reviews, the Cochrane Central Register of Controlled Trials and EMBASE (from 1980 to December 2008) were searched for English-language articles published between 1966 and 2008. This search was completed by a hand research accessing the references cited in all identified publications. Results: Nineteen studies were identified reporting outcomes after oral surgery procedures (mostly dental extractions in patients on OAT following different management protocols and haemostatic therapies). Five studies were randomized-controlled trials (RCTs), 11 were controlled clinical trials (CCTs) and three were prospective case series. The OAT management strategies as well as the protocols during and after surgery were different. This heterogeneity prevented any possible data aggregation and synthesis. The results from these studies are very homogeneous, reporting minor bleeding in very few patients, without a significant difference between the OAT patients who continue with the vitamin K antagonists vs. the patients who stopped this medication before surgery. These post-operative bleeding events were controlled only with local haemostatic measures: tranexamic acid mouthwashes, gelatine sponges and cellulose gauzes's application were effective. Post-operative bleeding did not correlate with the international normalised ratio (INR) status. In none of the studies was a thromboembolic event reported. Conclusions: OAT patients (INR 2,4) who do not discontinue the AC medication do not have a significantly higher risk of post-operative bleeding than non-OAT patients and they also do not have a higher risk of post-operative bleeding than OAT patients who discontinue the medication. In patients with OAT (INR 2,4) without discontinuation, topical haemostatic agents were effective in preventing post-operative bleeding. OAT discontinuation is not recommended for minor oral surgery, such as single tooth extraction or implant placement, provided that this does not involve autogenous bone grafts, extensive flaps or osteotomy preparations extending outside the bony envelope. Evidence does not support that dental implant placement in patients on OAT is contraindicated. [source] | ||||||||||||||||||||||||||||
