Comparing Minor Hand Procedures Performed with or without the Use of a Tourniquet: A Randomized Controlled Trial.
Ontology highlight
ABSTRACT: Background
Carpal tunnel syndrome and trigger finger are two of the most common conditions treated by the hand surgeon. During these procedures, a tourniquet is often used to minimize bleeding and improve visualization of the operative field. However, it may be associated with pain and discomfort. To date, there are few prospective studies investigating the safety and patient-centered outcomes of tourniquet-free minor hand procedures.Methods
This is a randomized controlled trial comparing patients undergoing open carpal tunnel or trigger finger release with or without the use of a tourniquet. Perioperative subjective patient experience was investigated for both techniques. This was measured based on a numerical rating scale for pain, anxiety, and overall satisfaction. In addition, this was an equivalence trial in terms of operative time, bleeding scores, and perioperative complication rates.Results
A total of 67 patients were recruited. Both groups were similar with respect to distribution of age, sex, handedness, anti-platelet use, and tobacco use. Median scores for operative time, anxiety, and overall satisfaction were comparable between the 2 groups. With regard to patient discomfort, median scores were significantly higher in the tourniquet group when compared with the no tourniquet group (3.58 versus 1.68, respectively, P = 0.02). Bleeding scores for the tourniquet group were significantly lower than for the no tourniquet group (1.14 versus 1.90, respectively, P = 0.001).Conclusions
The application of wide awake local anesthesia no tourniquet (WALANT) in minor hand surgery procedures has been shown to decrease tourniquet-associated discomfort, improving perioperative patient experience. Additionally, it demonstrated the noninferiority of the tourniquet-free technique with respect to operative time and the rate of perioperative complications.

Project description:BackgroundThe use of minor field sterility in hand/upper extremity cases has been shown to improve workflow efficiency while maintaining patient safety. As this finding has been limited to specific procedures, we investigated the safety of performing a wide array of hand/upper extremity procedures outside the main operating room using minimal field sterility with Wide-Awake Local Anaesthesia No Tourniquet (WALANT) anaesthesia by evaluating superficial and deep infection rates across a diverse series of cases.MethodsThis study was a case series conducted between October 2017 and June 2020. Of all, 217 patients underwent hand/upper extremity procedures performed in a minor procedure room via WALANT technique with field sterility. Primary outcome measures include superficial and deep surgical site infections within 14 days post-surgery.ResultsOf all, 217 patients were included in this study; 265 consecutive hand/upper extremity operations were performed by a single surgeon, with notable case diversity. The majority of patients (n = 215, 99.1%) did not report or present with signs of infection before or after their operation. We report 0% 14-day and 0.37% 30-day surgical site infection rates for such hand/upper extremity procedures performed in a minor procedure room with field sterility.ConclusionHand/upper extremity procedures performed via WALANT technique with field sterility in a minor procedure room are associated with low surgical site infection rates. These rates are comparable to surgical site infection rates for similar surgeries performed in main operating rooms with standard sterilization procedures. Thus, the implementation of this technique may allow for improved workflow efficiency and reduced waste, all while maintaining patient safety.

Project description:ImportanceSurgical procedures can be performed in different settings, but the association between the operative setting and patient safety and cost to the patient and payer is unknown.ObjectiveTo examine differences in complications, total payments, and out-of-pocket (OOP) spending for minor hand surgical procedures performed in office, ambulatory surgery center (ASC), and hospital outpatient department (HOPD) operative settings.Design, setting, and participantsA retrospective, population-based cohort study was conducted using deidentified claims data from private employer-sponsored health insurance from January 1, 2009, to December 31, 2017. Patients aged 18 years or older undergoing carpal tunnel release, trigger finger release, excision of wrist ganglion, and excision of small hand masses (N = 468 365) were included.ExposuresOperative setting, defined as procedures performed in the clinic setting, ASC, and HOPD.Main outcomes and measuresComplications during the 90-day postoperative period, total payments (total facility and payer reimbursement), and OOP spending.ResultsOf the 468 365 patients, 296 378 women (63.3%) and 171 987 men (36.7%) underwent minor hand surgical procedures from 2009 to 2017, with 284 889 procedures (60.8%) performed in HOPDs, 158 659 procedures (33.9%) performed in ASCs, and 24 817 procedures (5.3%) performed in the office setting. Ninety-day complications occurred in 3.4% of procedures performed in HOPDs, 3.3% in ASCs, and 2.9% in office settings (P < .001). After controlling for patient characteristics, procedures performed outside of the office had higher odds of complications (HOPDs: odds ratio [OR], 1.32; 95% CI, 1.22-1.43; ASCs: OR, 1.24; 95% CI, 1.14-1.34). Compared with the office setting, procedures performed in HOPDs incurred an extra $1216 in total payments (95% CI, $1184-$1248) and $115 in OOP expenses (95% CI, $109-$121). Procedures performed in ASCs cost an additional $709 (95% CI, $676-$741) and $140 in OOP expenses (95% CI, $134-$146). Transitioning ASC and HOPD procedures to the office setting could have saved an estimated $6 million annually in OOP expenses during the study period.Conclusions and relevanceThe findings of this study suggest that minor hand surgery performed in the office setting is safe and less costly compared with ambulatory and hospital-based operations. Shifting minor surgical procedures to the office setting may lead to substantial cost savings for payers and patients without compromising care quality.

Project description:In our experience, for all surgeries in the hand, the optimal epinephrine effect from local anesthesia-producing maximal vasoconstriction and visualization-is achieved by waiting significantly longer than the traditionally quoted 7 min from the time of injection.In this prospective comparative study, healthy patients undergoing unilateral carpal tunnel surgery waited either 7 min or roughly 30 min, between the time of injection of 1 % lidocaine with 1:100,000 epinephrine and the time of incision. A standardized incision was made through dermis and into the subcutaneous tissue followed by exactly 60 s of measuring the quantity of blood loss using sterile micropipettes.There was a statistically significant reduction in the mean quantity of bleeding in the group that waited roughly 30 min after injection and before incision compared to the group that waited only 7 min (95 % confidence intervals of 0.06?+?-0.03 ml/cm of incision, compared to 0.17?+?-0.08 ml/cm, respectively) (P?=?0.03).Waiting roughly 30 min after injection of local anesthesia with epinephrine as oppose to the traditionally taught 7 min, achieves an optimal epinephrine effect and vasoconstriction. In the hand, this will result in roughly a threefold reduction in bleeding-making wide awake local anesthesia without tourniquet (WALANT) possible. This knowledge has allowed our team to expand the hand procedures that we can offer using WALANT. The benefits of WALANT hand surgery include reduced cost and waste, improved patient safety, and the ability to perform active intraoperative movement examinations.

Project description:INTRODUCTION:Total knee arthroplasty is a highly effective treatment for end-stage knee osteoarthritis, and it is usually performed under spinal or general anaesthesia with or without a surgical tourniquet. Some debate about the preferred mode of anaesthesia regarding patient outcomes remains. The aim of this study, which compares general and spinal anaesthesia with and without a tourniquet on the outcomes of total knee arthroplasty, is to determine the optimal type of anaesthesia regimen and assess the effect of a tourniquet on the patient's recovery following total knee arthroplasty. METHODS AND ANALYSIS:This study is a randomised, controlled, parallel-group, four-arm study comparing spinal and general anaesthesia with and without a tourniquet in 400 patients undergoing fast-track total knee arthroplasty, with a 12-month follow-up. The primary outcome is cumulative intravenous oxycodone consumption by patient-controlled analgesia during the first 24 postoperative hours. Secondary outcomes include postoperative nausea and vomiting, the length of hospital stay, the duration of the surgery, blood loss, demand for surgical unit resources, complications, readmissions, postoperative knee function, range of motion, health-related quality of life, prolonged pain and mortality. ETHICS AND DISSEMINATION:This study's protocol is in accordance with the declaration of Helsinki. The results of this study will be disseminated in international peer-reviewed journals. TRIAL REGISTRATION NUMBER:NCT03364088; Pre-results.

Project description:BackgroundLower extremity amputation patients represent a frail group with extensive comorbidity. Transfemoral amputation is a high-risk procedure with 37-50% risk of mortality in the first year. Substantial blood loss during surgery increases the risk of anemic complications and death for these already weakened patients. The use of tourniquet during surgery may reduce blood loss, the need for blood transfusions, the related complications as well as the length of the surgery. However the use of tourniquet may be related to impaired wound healing and hence the use should be investigated in a randomized controlled trial. The primary aim of this study is to investigate the total blood loss and secondary to investigate differences in complications after transfemoral amputation between patients operated with or without tourniquet.MethodsThe total blood loss is calculated using Nadlers approach. Based on data from a pilot series, the sample size was calculated to 124, allocated 1:1 in two groups of 62 participants to ensure detection of at least 200 mL difference in the total blood loss. The primary outcome is the total blood loss. Secondary outcomes are blood transfusions, duration of surgery, length of hospital stay and risk of complications within 90 days (re-admissions, re-operations and mortality). Explorative outcomes are 1 year mortality and re-operation risk. Further explorative outcomes are postoperative quality of life (questionnaire EQ-5D-5L) and evaluation of number of prosthesis users including evaluation of prosthesis-specific function measured 3, 6, and 12 months postoperatively.DiscussionThe possibility to enhance patient safety is highly relevant and this trial will provide data for evidence based recommendations of best practice in amputation surgery.Trial registrationThe trial is registered on ClinicalTrials.gov with ID: NCT05550623. Initial release: 13/09 2022.

Project description:Tourniquet application is still a common practice in total knee arthroplasty (TKA) surgery despite being associated with several adverse effects. We evaluated the effects of tourniquet use on functional and clinical outcome and on knee range of motion (ROM).70 patients who underwent TKA were randomized into a tourniquet group (n = 35) and a non-tourniquet group (n = 35). All operations were performed by the same surgeon and follow-up was for 1 year. Primary outcomes were functional and clinical outcomes, as evaluated by KOOS and knee ROM. Secondary outcomes were intraoperative blood loss, surgical time and visibility, postoperative pain, analgesic consumption, and transfusion requirements.Patients in the non-tourniquet group showed a better outcome in all KOOS subscores and better early knee ROM from surgery to week 8. No difference was detected at the 6- and 12-month follow-ups. Postoperative pain and analgesic consumption were less when a tourniquet was not used. Surgical time and visibility were similar between groups. Intraoperative blood loss was greater when not using a tourniquet, but no postoperative transfusions were required.This study shows that TKA without the use of a tourniquet results in faster recovery in terms of better functional outcome and improved knee ROM. Furthermore, reduced pain and analgesic use were registered and no intraoperative difficulties were encountered.

Project description:BACKGROUND:Evidence is lacking to support the use of specialized anesthesia providers in minor surgical operations for patients without medical necessity. The authors sought to estimate the extent of potentially discretionary service use (anesthesiologist-administered anesthesia services among low-risk patients). METHODS:The authors performed a retrospective claims analysis using the Truven MarketScan Database to estimate the prevalence and cost of anesthesiologist-administered anesthesia services provided to patients undergoing minor hand surgery (i.e., carpal tunnel release, trigger finger release, or de Quervain release) from 2010 to 2015. A predictive probability model was created to estimate patient risk status. The authors examined the relationship between patient risk status and anesthesia use using multivariable regression models. RESULTS:Of 441,579 eligible procedures, 352,779 (80 percent) involved anesthesiologist-administered anesthesia services. The total proportion of estimated anesthesiologist-administered anesthesia use in low-risk patients who did not need anesthesiologist support declined over the study period (from 69.7 percent in 2010 to 65.8 percent in 2015). Although total payments for these services remained steady between 2010 and 2014, the average payment per procedure increased regardless of procedure type (from $376.8 in 2010 to $427.9 in 2015 for a carpal tunnel release operation). Approximately 83.7 percent of payments ($133 million) to anesthesia providers is credited to services in low-risk patients. CONCLUSIONS:Anesthesiologist-administered anesthesia services are commonly rendered to low-risk surgical patients. Existing health care reform efforts do not adequately address discretionary services that can be a targeted area for cost saving. It is important to consider the implications of potentially discretionary use of specialized anesthesia providers, particularly with the advancement of bundled payment models.

Project description:BACKGROUND:In a previous article ( https://doi.org/10.1007/s00701-019-03888-3 ), preliminary results of a survey, aiming to shed light on the number of surgical procedures performed and assisted during neurosurgery residency in Europe were reported. We here present the final results and extend the analyses. METHODS:Board-certified neurosurgeons of European Association of Neurosurgical Societies (EANS) member countries were asked to review their residency case logs and participate in a 31-question electronic survey (SurveyMonkey Inc., San Mateo, CA). The responses received between April 25, 2018, and April 25, 2020, were considered. We excluded responses that were incomplete, from non-EANS member countries, or from respondents that have not yet completed their residency. RESULTS:Of 430 responses, 168 were considered for analysis after checking in- and exclusion criteria. Survey responders had a mean age of 42.7 ± 8.8 years, and 88.8% were male. Responses mainly came from surgeons employed at university/teaching hospitals (85.1%) in Germany (22.0%), France (12.5%), the United Kingdom (UK; 8.3%), Switzerland (7.7%), and Greece (7.1%). Most responders graduated in the years between 2011 and 2019 (57.7%). Thirty-eight responders (22.6%) graduated before and 130 responders (77.4%) after the European WTD 2003/88/EC came into effect. The mean number of surgical procedures performed independently, supervised or assisted throughout residency was 540 (95% CI 424-657), 482 (95% CI 398-568), and 579 (95% CI 441-717), respectively. Detailed numbers for cranial, spinal, adult, and pediatric subgroups are presented in the article. There was an annual decrease of about 33 cases in total caseload between 1976 and 2019 (coeff. - 33, 95% CI - 62 to - 4, p = 0.025). Variables associated with lesser total caseload during residency were training abroad (1210 vs. 1747, p = 0.083) and female sex by trend (947 vs. 1671, p = 0.111), whereas case numbers were comparable across the EANS countries (p = 0.443). CONCLUSION:The final results of this survey largely confirm the previously reported numbers. They provide an opportunity for current trainees to compare their own case logs with. Again, we confirm a significant decline in surgical exposure during training between 1976 and 2019. In addition, the current analysis reveals that female sex and training abroad may be variables associated with lesser case numbers during residency.

Project description:IntroductionWhile windlass-rod style tourniquets stop bleeding in limbs when used by skilled responders, they are less successful in the hands of the untrained or not recently trained public. To improve usability, an academic-industry partnership developed the Layperson Audiovisual Assist Tourniquet (LAVA TQ). The LAVA TQ is novel in design and technology and addresses known challenges in public tourniquet application. A previously published multisite, randomized controlled trial of 147 participants showed that the LAVA TQ is much easier for the lay public to use compared to the Combat Application Tourniquet (CAT). This study evaluates the LAVA TQ's ability to occlude blood flow in humans compared to the CAT.MethodsThis study was a prospective, blinded, randomized controlled trial to demonstrate the non-inferiority of the LAVA TQ to occlude blood flow when applied by expert users compared to the CAT. The study team enrolled participants in Bethesda, Maryland, in 2022. The primary outcome was the proportion of blood flow occlusion by each tourniquet. The secondary outcome was surface application pressure for each device.ResultsThe LAVA TQ and CAT occluded blood flow in all limbs (21 LAVA TQ, 100%; 21 CAT, 100%). The LAVA TQ was applied at a mean pressure of 366 millimeters of mercury (mm Hg) (SD 20 mm Hg), and the CAT at a mean pressure of 386 mm Hg (SD 63 mm Hg) (P = 0.14).ConclusionThe novel LAVA TQ is non-inferior to the traditional windlass-rod CAT in occluding blood flow in human legs. The application pressure of LAVA TQ is similar to that used in the CAT. The findings of this study, coupled with LAVA TQ's demonstrated superior usability, make the LAVA TQ an acceptable alternative limb tourniquet.

Project description:ImportanceDespite increased focus on reducing opioid prescribing for long-term pain, little is known regarding the incidence and risk factors for persistent opioid use after surgery.ObjectiveTo determine the incidence of new persistent opioid use after minor and major surgical procedures.Design, setting, and participantsUsing a nationwide insurance claims data set from 2013 to 2014, we identified US adults aged 18 to 64 years without opioid use in the year prior to surgery (ie, no opioid prescription fulfillments from 12 months to 1 month prior to the procedure). For patients filling a perioperative opioid prescription, we calculated the incidence of persistent opioid use for more than 90 days among opioid-naive patients after both minor surgical procedures (ie, varicose vein removal, laparoscopic cholecystectomy, laparoscopic appendectomy, hemorrhoidectomy, thyroidectomy, transurethral prostate surgery, parathyroidectomy, and carpal tunnel) and major surgical procedures (ie, ventral incisional hernia repair, colectomy, reflux surgery, bariatric surgery, and hysterectomy). We then assessed data for patient-level predictors of persistent opioid use.Main outcomes and measuresThe primary outcome was defined a priori prior to data extraction. The primary outcome was new persistent opioid use, which was defined as an opioid prescription fulfillment between 90 and 180 days after the surgical procedure.ResultsA total of 36 177 patients met the inclusion criteria, with 29 068 (80.3%) receiving minor surgical procedures and 7109 (19.7%) receiving major procedures. The cohort had a mean (SD) age of 44.6 (11.9) years and was predominately female (23 913 [66.1%]) and white (26 091 [72.1%]). The rates of new persistent opioid use were similar between the 2 groups, ranging from 5.9% to 6.5%. By comparison, the incidence in the nonoperative control cohort was only 0.4%. Risk factors independently associated with new persistent opioid use included preoperative tobacco use (adjusted odds ratio [aOR], 1.35; 95% CI, 1.21-1.49), alcohol and substance abuse disorders (aOR, 1.34; 95% CI, 1.05-1.72), mood disorders (aOR, 1.15; 95% CI, 1.01-1.30), anxiety (aOR, 1.25; 95% CI, 1.10-1.42), and preoperative pain disorders (back pain: aOR, 1.57; 95% CI, 1.42-1.75; neck pain: aOR, 1.22; 95% CI, 1.07-1.39; arthritis: aOR, 1.56; 95% CI, 1.40-1.73; and centralized pain: aOR, 1.39; 95% CI, 1.26-1.54).Conclusions and relevanceNew persistent opioid use after surgery is common and is not significantly different between minor and major surgical procedures but rather associated with behavioral and pain disorders. This suggests its use is not due to surgical pain but addressable patient-level predictors. New persistent opioid use represents a common but previously underappreciated surgical complication that warrants increased awareness.
