Catheter Insertion (catheter + insertion)
Selected AbstractsUltra-miniature optical fiber pressure sensor with a sleeve for catheter insertionELECTRONICS & COMMUNICATIONS IN JAPAN, Issue 8 2009Masato Shimada Abstract A diaphragm-type optical fiber pressure sensor, which has a sleeve for fiber insertion, is proposed, and the fundamental characteristics of this sensor are demonstrated. The sleeve structure is fabricated by DRIE (Deep Reactive Ion Etching). The diaphragm with a sleeve is suitable for highly reliable and easy bonding between the sleeve and the optical fiber. The light intensity change detection by the Fabry,Perot interferometer based on the pressure is increased by the improved DRIE method. The mass production method of the developed diaphragm will be useful for creating a low-cost pressure sensor. © 2009 Wiley Periodicals, Inc.

Methods:, A prospective study using a written survey was carried out in the ED of a secondary level regional hospital in south-east Queensland. The survey conducted between August 2003 and November 2003 consisted of parental demographics, seven theoretical paediatric procedural scenarios with increasing level of procedural invasiveness (including resuscitation) and reasons for the decisions of parents to either stay with the child or leave the room. Parents of children with Australasian Triage Scale (ATS) triage category 3, 4 and 5 were surveyed. Results:, Of 573 surveys collected, 553 (96.5%) were completed correctly. The number of parents expressing a desire to be present during a procedure performed on their child was 519 (93.9%) for phlebotomy or i.v. cannulation of an extremity, 485 (87.7%) for nasogastric tube insertion, 461 (83.4%) for lumbar puncture, 464 (83.9%) for urinary catheter insertion, 430 (77.8%) for suprapubic bladder aspiration, 519 (93.4%) during procedural sedation and 470 (85%) during a resuscitation where the possibility existed that their child may die. The most common reason for wanting to be present was to provide comfort to their child (542/98%). The most common reason for not wanting to be present was a parental concern of getting in the way (181/33%). Conclusion:, Most parents surveyed would want to be present when invasive procedures are performed on their children in the ED. With increasing invasiveness, parental desire to be present decreased. However, the overwhelming majority of parents would want to be in attendance during procedural sedation or resuscitation. [source] Experience of prophylaxis treatment in children with severe haemophiliaHAEMOPHILIA, Issue 2 2002T. T. YEE The practice of prophylactic treatment of boys with severe haemophilia has been evaluated in our centre. Prophylaxis was started at the median age of 3.7 years (range 0.4,12.7 years) in 38/41 children (93%) under 17 years of age. Median follow-up was 4.1 years (range 0.4,12.7 years). The criteria of primary prophylaxis according to the definition by the European Paediatric Network of Haemophilia Management was fulfilled by 9/38 (24%). Although a majority [76%, 29/38] of the children started prophylaxis after a median number of joint bleeds of 3.5, 70% of the children in this group had clinical joint scores of 0. Intravenous catheter insertion was required at a median age of 15.5 months (range 5,36 months) in 21% of the children, resulting in a catheter infection rate of 1.74 per 1000 catheter days. None developed an inhibitor on prophylaxis and three patients who had low-titre inhibitors (< 5 Bethesda units) prior to prophylaxis had undetectable inhibitors after prophylaxis. The home-treatment training programme required considerable time and cost. As a result, 87% of the children used peripheral venous access and hospital visits declined as prophylaxis became established. Parents' incentives for prophylaxis were that the children undertook many physical activities and sports previously not recommended, there was less parental anxiety and an overall improvement in the quality of life for the whole family. [source] Determinants of C-reactive protein in chronic hemodialysis patients: Relevance of dialysis catheter utilizationHEMODIALYSIS INTERNATIONAL, Issue 2 2008Adriana HUNG Abstract Biomarkers of inflammation, especially C-reactive protein (CRP), have been consistently shown to predict poor outcomes in chronic hemodialysis (CHD) patients. However, the determinants of CRP and the value of its monitoring in CHD patients have not been well defined. We conducted a retrospective cohort study to evaluate possible determinants of the inflammatory response in CHD patients with a focus on dialysis catheter utilization. Monthly CRP were measured in 128 prevalent CHD patients (mean age 56.6 years [range 19,90], 68% African Americans, 39% diabetics [DM]) over a mean follow-up of 12 months (range 2,26 months). There were a total of 2405 CRP measurements (median 5.7 mg/L; interquartile range [IQR] 2.4,16.6 mg/L). The presence of a dialysis catheter (p<0.002), cardiovascular disease (p=0.01), male gender (p=0.005), higher white blood cell count (p<0.0001), elevated phosphorus (p=0.03), and lower cholesterol (p=0.02) and albumin (p<0.0001) concentrations were independent predictors of elevated CRP in the multivariate analysis. Additionally, CRP levels were significantly associated with the presence of a catheter, when comparing the levels before and after catheter insertion (p=0.002) as well as before and after catheter removal (p=0.009). Our results indicate that the presence of a hemodialysis catheter is an independent determinant of an exaggerated inflammatory response in CHD patients representing a potentially modifiable risk factor. [source] Analysis of factors affecting pain in intravenous catheter placement: a survey of 925 patientsINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 6 2005S. Soysal Summary The aim of the study was to determine some factors affecting pain during intravenous (i.v.) catheter placement in an emergency department (ED). A cross-sectional, observational study was conducted at an academic ED. Nine hundred and twenty five adult patients who had a 20 gauge i.v. catheter placed were enrolled the study. Patients were excluded for the following conditions: more than one i.v. attempt, altered mental status, head trauma, lack of contact due to visual impairment, hearing or speech disorder, intoxication, distracting injury or physical abnormality at the i.v. site. The magnitude of pain of i.v. catheter placement was not related to age, sex, experience of the individual placing the i.v. catheter, site of i.v. catheter insertion and use of analgesic or antidepressive drugs (p > 0.05). Patients with a history of depression reported significantly higher pain than non-depressive patients (p = 0.001). Depressive patients reported higher severity of pain during i.v. catheter placement than nondepressed ones. This may influence the decision on whether or not to use local anaesthesia for catheter insertion. [source] Central venous access for haemodialysis: prospective evaluation of possible complicationsJOURNAL OF CLINICAL NURSING, Issue 2 2007Denise De Andrade PhD Aims and objectives., The combination of chronic renal insufficiency and haemodialysis represents a challenge for health professionals. Chronic renal insufficiency patients undergoing haemodialysis treatment through a temporary double-lumen catheter were prospectively studied in order to identify the type and frequency of local and systemic complications. Methods., A six-month period was established with a view to the inclusion of new cases. Data were acquired through interviews, clinical assessment and patient records, and entered into a Microsoft Excel database through a double entry system and exported to the Statistical Package Social Sciences software. Sixty-four patients were evaluated prospectively, of which thirty-eight (59.4%) were men and 35 (54.7%) required catheter insertion for immediate treatment. During the study period, 145 catheters were inserted, ranging from 1 to 7 implants per patient, 29 (45.3%) were single insertions and 127 (87.6%) catheters were inserted into the jugular vein. The catheters were left in place for an average of 30 days. Results., Forty-one (64%) presented inadequate functioning, after about 26 days. A febrile state occurred in 24 (37.5%) patients after 34 days, secretion at the catheter entry site in 27 (42.2% after 26 days and bloodstream infection was encountered in 34(53%) after 34 days. Of the 61 blood culture samples, thirty (49%) were positive for Staphylococcus aureus that was the microorganism most frequently isolated. Conclusion., The findings indicate worrying aspects such as the catheters permanence time, exposing patients to different complications, including infection. Furthermore, inadequate catheter functioning leads to inefficient haemodialysis treatment. Relevance to clinical practice., Knowledge about complications allows for systematic care planning, prevention and control actions. [source] Major complications after 400 continuous popliteal sciatic nerve blocks for post-operative analgesiaACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2009V. COMPÈRE Background: A continuous popliteal sciatic nerve block (CPSNB) has been performed with increasing frequency for post-operative analgesia after foot surgery. Major complications associated with the placement of a perineural catheter remain rarely studied. The aim of this study was to prospectively determine the incidence of major complications (neurological and infectious) in post-operative adult patients with a continuous popliteal catheter inserted by the anatomical posterior approach for analgesia after foot surgery. Methods: All popliteal catheters were placed pre-operatively under sterile conditions with the aid of a nerve stimulator technique. The primary outcome measure was the incidence of major complications including infection and neuropathy. As a secondary outcome, adverse effects as well as other complications were also evaluated. Data were expressed as median [25th,75th percentiles]. Results: A total of 400 patients were included in the study during a 2-year period. The median time the catheter remained indwelling was 47 h [23, 54]. Major complications included three events (0.75%) with one infection (0.25%) and two neuropathies (0.50%). Three blocks were unsuccessful and the catheter insertion was difficult in 12 patients (3%). During the CPSNB procedure, one patient reported slight paraesthesia during stimulation. Patient satisfaction was scored at 4 for 89%, 3 for 6% and 2 for 5% on the analogue scale. Conclusions: Major complications after the use of CPSN are not in fact rare. The incidence of severe neuropathy or infection complications is, respectively, 0.50% and 0.25%. However, the insertion of CPSN could be considered effective and is associated with only a few minor complications. [source] Image-guided and -monitored renal artery stenting using only MRIJOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 5 2006Daniel R. Elgort PhD Abstract Purpose To demonstrate the ability of a unique interventional MR system to be used safely and effectively as the only imaging modality for all phases of MR-guided stent-supported angioplasty. Materials and Methods An experimental disease model of renal stenosis was created in six pigs. An interventional MR system, which employed previously reported tools for real-time catheter tracking with automated scan-plane positioning, adaptive image parameters, and radial true,FISP imaging with steady-state precession (True-FISP) imaging coupled with a high-speed reconstruction technique, was then used to guide all phases of the intervention, including: guidewire and catheter insertion, stent deployment, and confirmation of therapeutic success. Pre- and postprocedural X-ray imaging was used as a gold standard to validate the experimental results. Results All of the stent-supported angioplasty interventions were a technical success and were performed without complications. The average postoperative residual stenosis was 14.9%. The image guidance enabled the stents to be deployed with an accuracy of 0.98 ± 0.69 mm. Additionally, using this interventional MRI system to guide renal artery stenting significantly reduces the procedure time, as compared to using X-ray fluoroscopy. Conclusion This study has clearly demonstrated the first successful treatment of renal artery stenting in an experimental animal model solely under MRI guidance and monitoring. J. Magn. Reson.

[source] Ureteral catheter placement for prevention of ureteral injury during laparoscopic hysterectomyJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2008Yudai Tanaka Abstract Aim:, Ureteral injury is among the most devastating complications of gynecologic surgery. Estimated incidence of ureteral injury during laparoscopic hysterectomy is 2.6,35 times (0.2,6.0%) that in abdominal hysterectomy. We investigated preoperative ureteral catheter (UC) placement as a way to prevent ureteral injury in laparoscopic hysterectomy. Methods:, Clinical records of 94 women who underwent laparoscopic hysterectomy between February 2006 and January 2007 in Yazaki Hospital, Kanagawa, Japan, were reviewed retrospectively. Thirty-four patients between February and June 2006 underwent the surgery without ureteral catheterization and 60 patients between July 2006 and January 2007 underwent surgery with ureteral catheterization. Clinical outcomes were statistically compared between the two groups. Results:, The average time required for catheter insertion was 9.35 min. The ureter in which the catheter was placed was visualized clearly. In one patient, whose left ureter was deviated by a massive myoma, catheter insertion was not possible. No complications arose from catheter placement except for minor complaints including low back pain, urinary discomfort, and transient hamaturia. While one injury occurred in a patient without ureteral catheterization (1/34), no ureteral injury occurred in any patient with ureteral catheterization (0/60). Operative time, total blood loss, and hospital stay were not significantly different between the two groups. Conclusions:, UC placement is simple, helping to prevent ureteral injury during laparoscopic hysterectomy and enhancing safety of this procedure. [source] Transvaginal Hysterosalpingo-Contrast Sonography (HyCoSy) Compared with ChromolaparoscopyJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2000Dr. Somchai Tanawattanacharoen Abstract Objective: To compare the efficacy and safety of HyCoSy with chromolaparoscopy for the diagnosis of tubal occlusion and uterine abnormalities. Methods: Sixty infertile women in whom the cause of infertility was thought to be tubal occlusion or uterine abnormalities and who satisfied the inclusion and exclusion criteria as specified in the study protocol were included. HyCoSy was performed during the first half of the menstrual cycle at least 24 hours prior to chromolaparoscopy. The results from both HyCoSy and chromolaparoscopy were compared in assessing tubal occlusion and uterine pathology. Results: For the evaluation of fallopian tubes, we found corresponding results between HyCoSy and chromolaparoscopy in 80.0%. The agreement between both procedures in assessing the uterine pathology was 80.4%. Twenty-two women experienced adverse events. The most common complaint was pelvic pain. Other events encountered were: nausea (3 women) and vaginal bleeding (2 women). All events were thought to be not related to the study drug. Conclusion: HyCoSy showed good diagnostic performance in the evaluation of the fallopian tubes and uterus in infertile women. The adverse events reported in this study are minor and procedure-related (catheter insertion) rather than the trial substance.

[source] External jugular venous catheterization with a Groshong catheter for central venous access,JOURNAL OF SURGICAL ONCOLOGY, Issue 1 2008Mitsuru Ishizuka MD Abstract Background The Groshong catheter (GC) is commonly used as a peripherally inserted central catheter (PICC), and the external jugular vein (EJV) is not a common route for central venous access (CVA). Therefore, external jugular venous catheterization (EJVC) using a GC is rare. However, our experience has shown that this procedure is safe and simple for CVA. Purpose To assess the utility of EJVC using the GC for CVA. Methods CVA was done using a GC via the EJV with a single puncture employing the maximal barrier precaution technique. Results Between March 2005 and June 2007, we attempted to perform EJVC using a GC via the EJV for 331 patients. Among of these patients, 301 patients received successful catheterization (success rate: 301/331,=,90.9%). The total period of catheter insertion was 4601 days, and the mean insertion period was 15.1 days (range 2,147 days). The main complications of catheter insertion were malposition (8/301; 2.7%) and, oozing or hematoma formation (8/301; 2.7%). There were no severe complications such as nerve injury, pneumothorax or arterial bleeding. Conclusions Our experience demonstrates that EJVC using the GC is acceptable for CVA. J. Surg.

[source] Assessment of a New Model for Femoral Ultrasound-guided Central Venous Access Procedural Training: A Pilot StudyACADEMIC EMERGENCY MEDICINE, Issue 1 2010Michael C. Wadman MD Abstract Objectives:, Repetitive practice with feedback in residency training is essential in the development of procedural competency. Lightly embalmed cadaver laboratories provide excellent simulation models for a variety of procedures, but to the best of our knowledge, none describe a central venous access model that includes the key psychomotor feedback elements for the procedure, namely intravascular contents that allow for determination of correct needle position by either ultrasonographic imaging and/or aspiration or vascular contents. Methods:, A cadaver was lightly embalmed using a technique that preserves tissue texture and elasticity. We then performed popliteal fossa dissections exposing the popliteal artery and vein. Vessels were ligated distally, and 14-gauge catheters were introduced into the lumen of each artery and vein. The popliteal artery and vein were then infused with 200 mL of icterine/gel and 200 mL of methylene blue/gel, respectively. Physician evaluators then performed ultrasound (US)-guided femoral central venous line placements and rated the key psychomotor elements on a five-point Likert scale. Results:, The physician evaluators reported a median of 10.5 years of clinical emergency medicine (EM) experience with an interquartile range (IQR) of 16 and a median of 10 central lines placed annually (IQR = 10). Physician evaluators rated the key psychomotor elements of the simulated procedure as follows: ultrasonographic image of vascular elements, 4 (IQR = 0); needle penetration of skin, 4.5 (IQR = 1); needle penetration of vein, 5 (IQR = 1); US image of needle penetrating vein, 4 (IQR = 2); aspiration of vein contents, 3 (IQR = 2); passage of dilator into vein, 4 (IQR = 2); insertion of central venous catheter, 5 (IQR = 1); US image of catheter insertion into vein, 5 (IQR = 1); and overall psychomotor feedback of the simulated procedure compared to the evaluators' actual patient experience, 4 (IQR = 1). Conclusions:, For the key psychomotor elements of central venous access, the lightly embalmed cadaver with intravascular water-soluble gel infusion provided a procedural model that closely simulated clinicians' experience with patients.

Raghavan Background:, Ultrasonography is becoming an important adjunct in paediatric neuraxial blockade. Ultrasound guidance helps in visualisation of relevant neuraxial structures, predicting depth of epidural space from skin, reduction in bony contact and faster epidural placement. The visibility of neuraxial structures declines in patients as age increases. To date, there are no studies looking at the extent of spread of local anaesthetic solution in the epidural space and its correlation to the volume used, under ultrasound guidance. We report the results of our audit on spread of local anaesthetic solution in the epidural space in single shot caudal blocks. This abstract is based on the first 17 patients, the presentation will be based on all 50 patients. Methods:, This audit was approved by the local audit committee. We aimed to follow the extent of the spread of local anaesthetic within the epidural space with real time ultrasonography. Patients were selected when the planned anaesthetic included a single shot caudal block. The anaesthetists performing the anaesthetic and the caudal block consented to our ultrasound visualisation. All patients were below 5 years of age. No attempt was made to standardise the technique, the dose, or the speed of injection. After the placement of the caudal cannula by the primary anaesthetist involved in patient care, a separate anaesthetist, experienced in using ultrasound, visualised the neuraxial structures and subsequent spread of the local anaesthetic solution with real time ultrasound. The spread was followed during the injection and for 10 s after the completion of the injection. A 5 cm 7.5,12 MHz linear array was used longitudinally with either midline or paramedian approach. Results:, We are reporting the preliminary results from 17 patients. Patients were aged between 1 day and 1 year 10 months. They weighed between 3.3 kg and 14.6 kg. Either 22 gauge Jelco or Abbocath were used to perform the procedure; 0.25% or 0.20% L-bupivacaine was used on all occasions. The volume administered per kg ranged between 0.33 and 1.27 ml. The visibility of neuraxial structures was good on all occasions. On calculating the Spearmans correlation coefficient, the extent of spread of local anaesthetic in the epidural space was positively correlated with the volume used by a correlation coefficient of 0.64, with a P value of 0.008. The postoperative pain score in recovery was 0 in 16 out of the 17 cases. The one failure occurred when the observed spread would not have been expected to provide analgesia for the performed operation. Conclusions:, Among children below 5 years of age, there seems to be a positive correlation between the volume of local anaesthetic injected into the epidural space and the extent of its spread. This needs to be further investigated by a prospective randomised control trial. The utility of real time ultrasound to allow a reliable achievement of a desired level of sensory block, should be investigated i.e, whether the volume used in achieving a desired level of local anaesthetic spread, as guided by ultrasound, provides superior analgesia and fewer adverse effects compared with the volume calculated using the Armitage regimen.

[source] Audit of motor weakness and premature catheter dislodgement after epidural analgesia in major abdominal surgeryANAESTHESIA, Issue 1 2009I. Königsrainer Summary In a quality improvement audit on epidural analgesia in 300 patients after major abdominal surgery, we identified postoperative lower leg weakness and premature catheter dislodgement as the most frequent causes of premature discontinuation of postoperative epidural infusion. Lower limb motor weakness occurred in more than half of the patients with lumbar epidural analgesia. In a second period monitoring 177 patients, lumbar catheter insertion was abandoned in favour of exclusive thoracic placement for epidural catheters. Additionally, to prevent outward movement, the catheters were inserted deeper into the epidural space (mean (SD) 5.2 (1.5) cm in Period Two vs 4.6 (1.3) cm in Period One). Lower leg motor weakness declined from 14.7% to 5.1% (odds ratio 0.35; 95% confidence interval 0.16,0.74) between the two periods. Similarly, the frequency of premature catheter dislodgement was reduced from 14.5% to 5.7% (odds ratio 0.35; 95% confidence interval 0.17,0.72). With a stepwise logistic regression model we demonstrated that the odds of premature catheter dislodgement was reduced by 43% for each centimetre of additional catheter advancement in Period Two. We conclude that careful audit of specific complications can usefully guide changes in practice that improve success of epidural analgesia regimens. [source] QUADRAPOD MESH FOR POSTERIOR WALL RECONSTRUCTION IN ADULT INGUINAL HERNIASANZ JOURNAL OF SURGERY, Issue 3 2008Shih-Chung Wu Inguinal hernia repairs are the most frequently carried out operations worldwide, and open-mesh herniorrhaphies have gained wide acceptance for advantages of little tension, less pain and lower recurrence rates. Even so, potential drawbacks of original open-mesh repairs exist, and we accordingly make some modifications, suggesting a new ,quadrapod' marlex mesh as an alternative. From July 2002 to March 2004, we carried out 288 consecutive inguinal hernia repairs using quadrapod mesh in 273 patients, all of them were male and aged older than 35 years. Patient demographics, operative parameters, morbidity and outcomes were collected in detail. After surgery, patients were followed up every 6 months at one surgeon's clinic and any major abnormality was recorded. Mean age of the 273 patients was 58.7 years. Twenty-eight patients had recurrent hernias and 15 bilateral hernias. Mean surgical duration was 50.7 min. One patient suffered from major wound infection and needed prolonged hospitalization for parenteral antibiotics. Owing to old age and benign prostatic hyperplasia, 11 patients receiving spinal anaesthesia had temporary postoperative urine retention and needed short-term urinary catheter insertion. Most patients were discharged 1 day following surgery. Acute wound pain generally improved within days, and no patients complained of chronic pain or debility necessitating special interventions. With a mean follow up of 40.7 months, no case of recurrent herniation was detected to date. Open-mesh herniorrhaphy using quadrapod mesh provides a cheap, feasible and effective alternative choice in centres with limited resources. Preliminary results are encouraging, and a formal prospective study may be warranted. [source] Simultaneous bilateral percutaneous nephrolithotomy in childrenBJU INTERNATIONAL, Issue 1 2005Morshed A. Salah In the paediatric section, two papers relating to the upper urinary tract are presented. The first, from Hungary, describes simultaneous bilateral percutaneous nephrolithotomy in 13 patients, where it was deemed feasible; this is the first such report. Authors from London report on unilateral nephrectomy in patients with nephrogenic hypertension, and found that it was successful in normalising blood pressure in patients with renal hypertension with a normal contralateral kidney. OBJECTIVE To evaluate the efficacy of removing bilateral kidney stones simultaneously from children, in one session. PATIENTS AND METHODS Thirteen patients (three girls and 10 boys, 26 kidneys; mean age 8 years, range 3,14) underwent simultaneous bilateral percutaneous nephrolithotomy (PCNL) in the same session, under general anaesthesia, starting with ureteric catheter insertion into both kidneys and using a 26 F adult nephroscope. The mean (range) stone diameter was 2 (1,3.5) cm. Three patients had staghorn stones in one of their kidneys. Ultrasonic disintegration was used; two patients had bilateral and two others unilateral endopylotomy, and one patient had percutaneous suprapubic cystolithotomy in the same session. The mean (range) operative duration was 65 (55,90) min. RESULTS All patients were rendered stone-free; there was no severe bleeding or any other complication. On one side in one of the patients, a second session was needed because of residual stone. The nephrostomy tubes were removed 3 and 4 days after PCNL and the hospital stay was 6 (1,11) days. CONCLUSION The advantages of simultaneous bilateral PCNL are reduced psychological stress, one cystoscopy and anaesthesia, less medication and a shorter hospital stay and convalescence, with considerable savings in cost. In experienced hands this method can be used not only in adults but also in children. To our knowledge this is the only report of this technique in children. [source] Procedural Pain Management Patterns in Academic Pediatric Emergency DepartmentsACADEMIC EMERGENCY MEDICINE, Issue 5 2007Rishi Bhargava MD ObjectivesTo describe the current state of the art for pain and sedation management for five common pediatric emergency department (ED) procedure scenarios. MethodsFellowship directors of U.S. EDs with a pediatric emergency medicine fellowship training program were surveyed by mail and asked to choose the one most commonly used pain or sedation management option for five clinical scenarios: facial laceration repair, cranial computed tomography in a toddler, closed fracture reduction, neonatal lumbar puncture, and intravenous catheter insertion. Results were analyzed by using descriptive statistics, and the differences between high and low volume departments were compared by using a chi-square test. ResultsThirty-eight of 51 fellowship programs responded (75%). The majority of respondents were fellowship directors (76%). Topical anesthetics were most commonly reported as used for a simple facial laceration (84%), whereas ketamine sedation was most popular for fracture reduction (86%). Pain management for the other scenarios was more variable. More than half of the respondents (53%) would not sedate at all for cranial computed tomography, and only 38% reported use of pharmacologic pain management for intravenous catheter insertion. The majority (74%) reported use of anesthetic (topical or injected local) for neonatal lumbar puncture. High volume departments were more likely to use pain management for intravenous catheter insertions. ConclusionsPain and sedation management methods for pediatric procedures continue to evolve. Despite gains, there is still room for improvement, particularly regarding intravenous catheter insertions. [source] | |||||||||||||||||||||||||
