Electrosurgery, Pacemakers and ICDs: A Survey of Precautions and Complications Experienced by Cutaneous Surgeons

DERMATOLOGIC SURGERY, Issue 4 2001
Hazem M. El-Gamal MD
Background. Minimal information is available in the literature regarding the precautions implemented or complications experienced by cutaneous surgeons when electrosurgery is used in patients with pacemakers or implantable cardioverter-defibrillators (ICDs). The literature pertinent to dermatologists is primarily based on experiences of other surgical specialties and a generally recommended thorough perioperative evaluation. Objective. To determine what precautions are currently taken by cutaneous surgeons in patients with pacemakers or ICDs, and what types of complications have occurred due to electrosurgery in a dermatologic setting. Methods. In the winter of 2000, a survey was mailed to 419 U.S.-based members of the American College of Mohs Micrographic Surgery and Cutaneous Oncology (ACMMSCO). Results. A total of 166 (40%) surveys were returned. Routine precautions included utilizing short bursts of less than 5 seconds (71%), use of minimal power (61%), and avoiding use around the pacemaker or ICD (57%). The types of interference reported were skipped beats (eight patients), reprogramming of a pacemaker (six patients), firing of an ICD (four patients), asystole (three patients), bradycardia (two patients), depleted battery life of a pacemaker (one patient), and an unspecified tachyarrhythmia (one patient). Overall there was a low rate of complications (0.8 cases/100 years of surgical practice), with no reported significant morbidity or mortality. Bipolar forceps were utilized by 19% of respondents and were not associated with any incidences of interference. Conclusions. Significant interference to pacemakers or ICDs rarely results from office-based electrosurgery. No clear community practice standards regarding precautions was evident from this survey. The use of bipolar forceps or true electrocautery are the better options when electrosurgey is required. These two modalities may necessitate fewer perioperative precautions than generally recommended, without compromising patient safety. [source]


Interpreting three-dimensional structures from two-dimensional images: a web-based interactive 3D teaching model of surgical liver anatomy

HPB, Issue 6 2009
Jodi L. Crossingham
Abstract Background:, Given the increasing number of indications for liver surgery and the growing complexity of operations, many trainees in surgical, imaging and related subspecialties require a good working knowledge of the complex intrahepatic anatomy. Computed tomography (CT), the most commonly used liver imaging modality, enhances our understanding of liver anatomy, but comprises a two-dimensional (2D) representation of a complex 3D organ. It is challenging for trainees to acquire the necessary skills for converting these 2D images into 3D mental reconstructions because learning opportunities are limited and internal hepatic anatomy is complicated, asymmetrical and variable. We have created a website that uses interactive 3D models of the liver to assist trainees in understanding the complex spatial anatomy of the liver and to help them create a 3D mental interpretation of this anatomy when viewing CT scans. Methods:, Computed tomography scans were imported into DICOM imaging software (OsiriXÔ) to obtain 3D surface renderings of the liver and its internal structures. Using these 3D renderings as a reference, 3D models of the liver surface and the intrahepatic structures, portal veins, hepatic veins, hepatic arteries and the biliary system were created using 3D modelling software (Cinema 4DÔ). Results:, Using current best practices for creating multimedia tools, a unique, freely available, online learning resource has been developed, entitled Visual Interactive Resource for Teaching, Understanding And Learning Liver Anatomy (VIRTUAL Liver) (http://pie.med.utoronto.ca/VLiver). This website uses interactive 3D models to provide trainees with a constructive resource for learning common liver anatomy and liver segmentation, and facilitates the development of the skills required to mentally reconstruct a 3D version of this anatomy from 2D CT scans. Discussion:, Although the intended audience for VIRTUAL Liver consists of residents in various medical and surgical specialties, the website will also be useful for other health care professionals (i.e. radiologists, nurses, hepatologists, radiation oncologists, family doctors) and educators because it provides a comprehensive resource for teaching liver anatomy.

The occurrence of intra-operative hypotension varies between hospitals: observational analysis of more than 147,000 anaesthesia

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2009
P. TAFFÉ
Background: Hypotension, a common intra-operative incident, bears an important potential for morbidity. It is most often manageable and sometimes preventable, which renders its study important. Therefore, we aimed at examining hospital variations in the occurrence of intra-operative hypotension and its predictors. As secondary endpoints, we determined to what extent hypotension relates to the risk of post-operative incidents and death. Methods: We used the Anaesthesia Databank Switzerland, built on routinely and prospectively collected data on all anaesthesias in 21 hospitals. The three outcomes were assessed using multi-level logistic regression models. Results: Among 147,573 anaesthesias, hypotension ranged from 0.6% to 5.2% in participating hospitals, and from 0.3% up to 12% in different surgical specialties. Most (73.4%) were minor single events. Age, ASA status, combined general and regional anaesthesia techniques, duration of surgery and hospitalization were significantly associated with hypotension. Although significantly associated, the emergency status of the surgery had a weaker effect. Hospitals' odds ratios for hypotension varied between 0.12 and 2.50 (P,0.001), even after adjusting for patient and anaesthesia factors, and for type of surgery. At least one post-operative incident occurred in 9.7% of the procedures, including 0.03% deaths. Intra-operative hypotension was associated with a higher risk of post-operative incidents and death. Conclusion: Wide variations remain in the occurrence of hypotension among hospitals after adjustment for risk factors. Although differential reporting from hospitals may exist, variations in anaesthesia techniques and blood pressure maintenance may also have contributed. Intra-operative hypotension is associated with morbidities and sometimes death, and constant vigilance must thus be advocated. [source]


How can we prepare medical students for theatre-based learning?

MEDICAL EDUCATION, Issue 10 2007
Nishan Fernando
Context, The quality of medical undergraduate operating theatre-based teaching is variable. Preparation prior to attending theatre may support student learning. Identifying and agreeing key skills, competences and objectives for theatre-based teaching may contribute to this process of preparation. Methods, We carried out a cross-sectional survey of consultant surgeons and students using a forced choice questionnaire containing 16 skills and competences classified as ,essential', ,desirable' or ,not appropriate', and a choice of 6 different teaching methods, scored for perceived effectiveness on a 5-point Likert scale. Questionnaire content was based on the findings from an earlier qualitative study. Results, Comparative data analyses (Mann, Whitney and Kruskal,Wallis tests) were carried out using spss Version 14. A total of 42 consultant surgeons and 46 students completed the questionnaire (46% and 100% response rates, respectively). Knowledge of standard theatre etiquette and protocols, ability to scrub up adequately, ability to adhere to sterile procedures, awareness of risks to self, staff and patients, and appreciation of the need for careful peri-operative monitoring were considered ,essential' by the majority. Student and consultant responses differed significantly on 5 items, with students generally considering more practical skills and competences to be essential. Differences between students on medical and surgical attachments were also identified. Conclusions, Consultant surgeons and medical students agree on many aspects of the important learning points for theatre-based teaching. Compared with their teachers, students, particularly those on attachment to surgical specialties, are more ambitious , perhaps overly so , in the level of practical skills and risk awareness they expect to gain in theatre.

Factors affecting future choice of specialty among first-year medical students of the University of the West Indies, Trinidad

MEDICAL EDUCATION, Issue 1 2007
Nelleen S Baboolal
Background, This study was conducted to determine factors that influence career choice among 1st-year medical students. Design And Methods, A cross-sectional survey of 170 1st-year medical students from the University of the West Indies, St Augustine Campus was undertaken with a questionnaire designed to assess their perceptions of careers in various specialties. Likert scales were used to quantify the reasons for their preferences. Results, The response rate was 136/170 (80%). The age of respondents ranged from 16 to 36 years, mean 20.45, SD 2.88. Of the generic factors students considered important in their choice of a specialty, students ranked the ability to help patients the highest (rating of 1.44), along with the diagnosis and treatment of disease second (rating of 1.49); 38 (27.9%) cited medicine, 26 (19.1%) surgery, 13 (9.6%) paediatrics, 10 (7.4%) family practice and 4 (2.9%) psychiatry as their chosen career. Students begin their medical training with the view that a career in psychiatry is less attractive than other specialties surveyed. The average attractiveness was estimated as surgery 1.64, medicine, 1.81, paediatrics 1.95 and psychiatry 2.57. The differences between the averages were highly significant (F = 57.6, P < 0.001). Conclusion, The findings suggest that although 1st-year medical students rank the diagnosis and treatment of disease and the ability to help patients as the greatest influence in choosing a specialty, internal medicine was the most popular chosen career, while the surgical specialties were identified as the most attractive. Medical students have serious reservations about psychiatry as a career choice. [source]


Doctors' reasons for rejecting initial choices of specialties as long-term careers

MEDICAL EDUCATION, Issue 4 2003
Trevor W Lambert
Objectives, To report on rejected choices of specialty as long-term careers and reasons for rejection. Design, Postal questionnaire survey. Setting, United Kingdom. Participants, All graduates of 1996 and 1999 from UK medical schools during their first year after qualification. Main outcome measures, Any career choice which had been seriously considered and rejected and the reason for its rejection. Results, In all, 33·1% (1871) of respondents named a rejected choice and gave reasons for its rejection. Disproportionately high numbers rejected the surgical specialties, paediatrics and obstetrics and gynaecology (O&G), using the specialty distribution of positive choices as the comparator. Relatively few doctors rejected general practice (GP) after giving it serious consideration. Doctors rejecting the hospital medical and surgical specialties or paediatrics were most likely to specify reasons relating to quality of life. Three-quarters of the graduates of 1999 who rejected O&G did so because of poor career prospects. Conclusions, Quality of life issues, and concerns about working relationships, are sufficiently influential to persuade many doctors to abandon an initial choice of medical career. It is unlikely that much of the decline in entry to GP is attributable to rejection of GP by doctors who initially chose it. The decline must therefore represent an increase in the number of doctors who had never seriously considered it as a long-term career choice. [source]

Intraoperative magnification: Who uses it?,

MICROSURGERY, Issue 6 2004
Ch.B. FRCS Ed (Tr. & Orth.), Paul Max Jarrett M.B.
Surgeons over recent decades have made increasing use of intraoperative magnification to enhance the outcome of surgical procedures, yet no published information exists regarding the extent of magnification use within surgical specialties. A sample of surgeons consisting of 148 specialists and senior surgical trainees in the west of Scotland was surveyed by postal questionnaire regarding their frequency and types of magnification use. Patterns of use were similar within each specialty, but varied markedly between specialties. Otolaryngologists and plastic, maxillofacial, and ophthalmic surgeons use both loupes and microscopes frequently. Cardiothoracic and pediatric surgeons tend only to utilize loupes, whereas neurosurgeons tend only to use microscopes. General surgeons, urologists, orthopedic surgeons, and gynecologists are infrequent users or nonusers of magnification, and when required will utilize loupes rather than microscopes. As a clear pattern of magnification use exists, it should be possible to anticipate the equipment needs of surgeons when providing theater services. © 2004 Wiley-Liss, Inc.

Mortality and cancer incidence in a cohort of registered nurses from British Columbia, Canada

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 12 2007
Helen Dimich-Ward PhD
Abstract Background A retrospective cohort study of provincial registered nurses (RNs) from British Columbia, Canada was undertaken to determine risks of mortality and cancer incidence; in particular for breast cancer and leukemia. Methods Cohort records of RNs from 1974 to 2000 were linked to Canadian death and cancer registries. Analyses included standardized mortality (SMR) and incidence ratios (SIR) as well as relative risks for internal comparisons. Results There were 58,125 RNs in the cohort (96.7% females). The SMR for all causes of mortality for female RNs was low, at 0.61 (95% CI, 0.58,0.64). The only elevated SIR for female RNs was for malignant melanoma (1.27; 95% CI, 1.10,1.46). Ever working in a hospital, medical surgical specialties or maternal/pediatrics showed some elevated cancer risks. Conclusions Low SMRs for the female RN cohort suggest healthful lifestyles and a healthy worker effect. Length of employment as a nurse, in hospitals and in specific fields was associated with some increased risks of cancer. Am. J. Ind. Med. 50:892,900, 2007. © 2007 Wiley-Liss, Inc. [source]


Nurturing of surgical careers by the wellington surgical interest club

ANZ JOURNAL OF SURGERY, Issue 4 2009
Sanket Srinivasa
The Royal Australasian College of Surgeons (RACS) has recently introduced the new Surgical Education and Training programme. The purpose of this was, in part, to help address the anticipated shortage of surgeons in the future, by streamlining the surgical training programme. The formation of the Wellington Surgical Interest Club (WSIC), a student-led initiative, had several complementary goals. These included the desire to identify potential candidates for a career in surgery, promote a surgical career to students especially women, help students acquire basic surgical skills early, inform students about surgical careers, promote student involvement in surgical research and to create an effective mentorship model during undergraduate and junior surgical training. The strengths of WSIC are its goals, which are similar to those of the RACS with regard to promoting surgery as a career option; its easy reproducibility at other medical institutions; its ability to focus on issues of relevance to both students and junior doctors; and being a bridging solution at a time when early exposure to surgical specialties is both desired and necessary.

Workplace-based assessment: assessing technical skill throughout the continuum of surgical training

ANZ JOURNAL OF SURGERY, Issue 3 2009
Jonathan Beard
Abstract The Royal Colleges of Surgeons and Surgical Specialty Associations in the UK have introduced competence-based syllabi and curricula for surgical training. The syllabi of the Intercollegiate Surgical Curriculum Programme (ISCP) and Orthopaedic Curriculum and Assessment Programme (OCAP) define the core competencies, that is, the observable and measureable behaviours required of a surgical trainee. The curricula define when, where and how these will be assessed. Procedure-based assessment (PBA) has been adopted as the principal method of assessing surgical skills. It combines competencies specific to the procedure with generic competencies such as safe handling of instruments. It covers the entire procedure, including preoperative and postoperative planning. A global summary of the level at which the trainee performed the assessed elements of the procedure is also included. The form has been designed to be completed quickly by the assessor (clinical supervisor) and fed-back to the trainee between operations. PBA forms have been developed for all index procedures in all surgical specialties. The forms are intended to be used as frequently as possible when performing index procedures, as their primary aim is to aid learning. At the end of a training placement the aggregated PBA forms, together with the logbook, enable the Educational Supervisor and/or Programme Director to make a summary judgement about the competence of a trainee to perform index procedures to a given standard.

A NEW SURGICAL EDUCATION AND TRAINING PROGRAMME

ANZ JOURNAL OF SURGERY, Issue 7 2007
John P. Collins
Educating and training tomorrow's surgeons has evolved to become a sophisticated and expensive exercise involving a wide range of learning methods, opportunities and stakeholders. Several factors influence this process, prompting those who provide such programmes to identify these important considerations and develop and implement appropriate responses. The Royal Australasian College of Surgeons embarked on this course of action in 2005, the outcome of which is the new Surgical Education and Training programme with the first intake to be selected in 2007 and commence training in 2008. The new programme is competency based and shorter than any designed previously. Implicitly, it recognizes in the curriculum and assessment development and processes, the nine roles and their underpinning competencies identified as essential for a surgeon. It is an evolution of the previous programme retaining that which has been found to be satisfactory. There will be one episode of selection directly into the candidate's specialty of choice and those accepted will progress in an integrated and seamless fashion, provided they meet the clinical and educational requirements of each year. The curriculum and assessment in the basic sciences include both generic and specially aligned components from the commencement of training in each of the nine surgical specialties. Born of necessity and developed through extensive research, discussion and consensus, the implementation of this programme will involve many challenges, particularly during the transition period. Through cooperation, commitment and partnerships, a more efficient and better outcome will be achieved for trainees, their trainers and their patients. [source]


THE LENGTH OF SUPERFICIAL TEMPORAL ARTERY BIOPSIES

ANZ JOURNAL OF SURGERY, Issue 6 2007
Neil S. Sharma
Background: To compare temporal artery biopsy specimen lengths from a tertiary care and a community hospital in New South Wales to recommended clinical guidelines in suspected giant cell arteritis. Design: A retrospective observational study of all patients who underwent temporal artery biopsy at Bathurst Base Hospital (BBH) and Royal Prince Alfred Hospital (RPAH) over a 5-year period. Methods: Patients who underwent temporal artery biopsy during the 5-year period were identified using computerized hospital databases. A retrospective chart review was carried out on all cases. Data were collected regarding patient age, patient sex, length of biopsy specimen, histopathological results and surgical team carrying out the biopsy. Results: During the 5-year period, 157 temporal artery biopsies were carried out at both hospitals, with 38/157(24%) at BBH and 119/157 (76%) at RPAH. There was no significant difference in biopsy length at the two hospitals. The mean specimen length at BBH was 12.1 mm compared with 11.7 mm at RPAH (t = 0.35; P = 0.73). At RPAH, there was no significant difference in specimen length between the surgical specialties carrying out the biopsy (anovaF = 1.37; P = 0.26). Specimens of length 20 mm or greater were 2.8 times more likely to show features of giant cell arteritis than those less than 20 mm. Conclusion: The mean length of temporal artery biopsy specimens at both hospitals was substantially shorter than recommended guidelines of a minimum 20 mm. We recommend all surgeons carrying out temporal artery biopsies ensure a specimen of sufficient length is obtained. [source]


Single-port surgery: Current applications and limitations

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2009
GV Rao
Abstract Introduction: In an attempt to further enhance the benefits of cosmesis and reduced morbidity of minimally invasive surgery, single-port (incision) laparoscopic surgery (SPS) has emerged as a bridge between conventional laparoscopy and natural orifice transluminal endoscopic surgery. As the expertise and instrumentation required are an extension of standard laparoscopic techniques, SPS has been adapted for a variety of procedures and specialties in a short span of time. Discussion: In this article, we discuss the various SPS techniques, as well as the new devices and instrumentation available for facilitating SPS. We also review current applications reported for SPS in various surgical specialties. We present a comprehensive review of the potential benefits, limitations and risks of these novel techniques. Conclusion: Initial reports have demonstrated the technical feasibility and safety of SPS for a wide range of surgical applications. With specialized instrumentation and refinement of technique, its role will increase in coming years. Future work is necessary to improve existing instrumentation, to increase clinical experience and to assess the benefits of this surgical approach. [source]


Sir William Mackenzie: sympathetic ophthalmia and glaucoma before ophthalmoscopy

ANZ JOURNAL OF SURGERY, Issue 12 2009
Geoffrey Serpell
Abstract One of the practitioners of probably the oldest surgical specialty, ophthalmic, was the eminent Scottish ophthalmologist, Sir William Mackenzie. Educated in Edinburgh, he moved to Glasgow, and described and named sympathetic ophthalmia before the time of the ophthalmoscope, well defining his powers of observation and deduction. Founding the Glasgow Eye Infirmary, his ,Practical Treatise on Diseases of the Eye' appeared in English in four editions (1850,1884) and in French and German. In this also appears the first full and clear account of glaucoma. Both he and the illustrator of his book, Wharton Jones, moved to Glasgow because of rather indefinite connections with Robert Knox, the anatomist, who was allegedly helped by the bodysnatchers, Burke and Hare. Mackenzie and his book were highly regarded before the revolutionary ophthalmoscope. He was knighted and appointed Surgeon Oculist to the Queen in Scotland. [source]


Burnout in Australasian Younger Fellows

ANZ JOURNAL OF SURGERY, Issue 9 2009
Sarah Benson
Abstract Background:, Burnout is the state of prolonged physical, emotional and psychological exhaustion characteristic of individuals working in human service occupations. This study examines the prevalence of burnout among Younger Fellows of the Royal Australasian College of Surgeons and its relationship to demographic variables. Methods:, In March 2008, a survey was sent via email to 1287 Younger Fellows. This included demographic questions, a measure of burnout (Copenhagen Burnout Inventory), and an estimate of social desirability (Marlowe,Crowne Social Desirability Scale , Form C). Results:, Females exhibited higher levels of personal burnout (P < 0.001) and work-related burnout (P < 0.025), but no significant difference in patient-related burnout. Younger Fellows in hospitals with less than 50 beds reported significantly higher patient-related burnout levels (mean burnout 37.0 versus 22.1 in the rest, P= 0.004). An equal work division between public and private practice resulted in higher work-related burnout than concentration of work in one sector (P < 0.05). Younger Fellows working more than 60 hours per week reported significantly higher personal burnout than those who worked less than this (P < 0.05). There was no significant correlation between age, country of practice, surgical specialty and any of the burnout subscales. Conclusion:, Female surgeons, surgeons that work in smaller hospitals, those that work more than 60 h per week, and those with practice division between the private and public sectors, are at a particularly high risk of burnout. Further enquiry into potentially remediable causes for the increased burnout in these groups is indicated. [source]


Ensuring a graduated integrated progression of learning in a changing environment

ANZ JOURNAL OF SURGERY, Issue 3 2009
W. E. G. Thomas
Abstract Surgical training is under threat in the changing environment of today. In the past, training consisted of an apprenticeship, which is no longer feasible or practical within the time limitation imposed on trainees currently, and so a new and innovative approach is required to train the surgeons of tomorrow. There is therefore a need for an explicit curriculum that ensures a graduated and integrated progression of learning in which both trainees and trainers are aware of what is required for each stage in training and for each surgical specialty. Such a curriculum has now been developed in the UK. [source]


Emergency Medicine Career Choice: A Profile of Factors and Influences from the Association of American Medical Colleges (AAMC) Graduation Questionnaires

ACADEMIC EMERGENCY MEDICINE, Issue 6 2009
Jeremy S. Boyd
Abstract Objectives:, This study sought to account for trends in medical student specialty choice by examining the importance of lifestyle factors. Emergency medicine (EM) is among several medical specialties classified as having a "controllable lifestyle." The primary objective of this study was to determine if medical students choosing careers in EM have a different profile of influences, values, and expectations from students choosing other specialties or specialty groups. Of secondary interest was how much lifestyle influenced students choosing EM compared to students choosing controllable lifestyle (CL) specialties. Methods:, Using data from the 2005 and 2006 Association of American Medical Colleges (AAMC) graduation questionnaire (GQ) supplemental surveys, we grouped responses according to desired specialty choice: EM (n = 963), CL (n = 3,681), primary care (PC; n = 3,191), or surgical specialty (SS; n = 1,694). The survey requires students to rate the influence of nine specific factors in determining their specialty choice: lifestyle, competitiveness, high level of educational debt, mentors and role models, options for fellowship training, salary expectations, length of residency training, family expectations, and medical school career planning activities. Using one-way analysis of variance (ANOVA) and nonparametric statistics, we assessed responses among the four subgroups for differences in the importance attributed to these factors. Results:, A total of 13,440 students completed the two supplemental surveys of the GQ. Of these students, 9,529 identified a specialty choice that fell within one of the four comparison groups and were included in the analysis. Compared to other specialty groups, students choosing EM reported lifestyle and length of residency as strong influences, while attributing less influence to mentors and options for fellowship training. Conclusions:, Students choosing a career in EM have distinctly different priorities and influences than students entering PC and SS. The profile of students who choose EM is very similar to those choosing traditional CL specialties. A more thorough understanding of the values and priorities that shape medical student career selection may allow educators to provide better career counseling. [source]
