A comprehensive review of epinephrine in the finger: to do or not to do

A Multicenter Prospective Study of 3,110 Consecutive Cases of Elective Epinephrine Use in the Fingers and Hand: The Dalhousie Project Clinical Phase

PURPOSE

To examine prospectively the incidence of digital infarction and phentolamine rescue in a large series of patients in whom local anesthesia with adrenaline was injected electively into the hand and fingers. There continues to be a commonly held belief that epinephrine injection is contraindicated in the finger despite a lack of valid evidence to support this concept in the literature.

METHODS

From 2002 to 2004 there were 9 hand surgeons in 6 cities who prospectively recorded each consecutive case of elective hand and finger epinephrine injection. They recorded each instance of skin or tissue loss and the number of times phentolamine reversal of adrenaline vasoconstriction was required.

RESULTS

There were 3,110 consecutive cases of elective injection of low-dose epinephrine (1:100,000 or less) in the hand and fingers and none produced any instance of digital tissue loss. Phentolamine was not required to reverse the vasoconstriction in any patients.

CONCLUSIONS

The true incidence of finger infarction in elective low-dose epinephrine injection into the hand and finger is likely to be remote, particularly with the possible rescue with phentolamine.

The 100 most-cited articles in WALANT hand surgery: A bibliometric and visualized analysis

This bibliometric analysis aimed to define important topics and developments across wide awake local anaesthesia no tourniquet (WALANT) hand surgery, an innovative ambulatory technique that gained popularity during the COVID-19 pandemic. Articles were searched and screened using the Web of Science core collection database. VOSviewer 1.6.18 and bibliometrix were used for analysis. In the initial search 419 articles were found. Between 1990 and 2023, 333 writers contributed to the top 100 most-cited articles published. The country with the highest number of published articles (20%) was Canada, followed by the USA (18%) and China (12%). Most articles were published in Plastic and Reconstructive Surgery (15%), Hand Clinics (14%) and the European and American volumes of The Journal of Hand Surgery (9% each). Eighty-two percent of articles had a Level of Evidence of III or V. High-quality randomized controlled trials and systematic reviews of WALANT are needed to broaden and enhance clinical practice and research.Level of evidence: V.

Complications in nail surgery and prevention strategies: a comprehensive review

Nail surgery, commonly performed to manage a wide range of nail disorders, is associated with potential complications that can affect patient's recovery and outcomes. This review provides a detailed overview of these possible complications and strategies for their prevention. Surgical complications in nail procedures can be classified into specific and non-specific. Specific complications are associated with damage to particular structures of the nail unit, such as the matrix, nail bed, or hyponychium. Non-specific complications, such as hematoma, infection, and necrosis, may be a consequence of any surgical procedure and are not directly related to the anatomical structures involved in the operation. Recognizing factors that can contribute to these complications, such as the choice of surgical techniques, patient comorbidity management, and the implementation of postoperative care practices, is essential to reduce their incidence. This work reports the current evidence and best practices in order to reduce surgical risks and improve patient outcomes. Examining each complication and its prevention strategies in detail, this review is a practical resource for clinicians who manage nail surgery cases.

Patient satisfaction using wide-awake local anaesthesia no tourniquet (WALANT) in adults undergoing elective hand surgery: A systematic review and meta-analysis

BACKGROUND

Wide-awake local anaesthesia no tourniquet (WALANT) is increasing in popularity within hand surgery. However, evidence is unclear on patient satisfaction rates when WALANT is compared against more traditional anaesthetic techniques where pneumatic tourniquets are used. The present study aimed to evaluate the satisfaction rates of patient with the WALANT technique.

METHODS

A literature search was performed using the PubMed, Embase and Cochrane databases for observational studies and randomised controlled trials (RCTs) from 2003 up to June 2023. The review was carried out among adults undergoing elective hand surgery. The mean difference in operation time and standardised mean difference (SMD) for patient satisfaction and post-operative pain (<24 h) were computed using the random effects model. The quality of studies was evaluated using RoB-2 for RCTs and risk of bias in non-randomised studies ROBINS-I for observational studies. Data were collated and a meta-analysis was performed.

RESULTS

Five RCTs and 15 observational studies were included in our analysis, comprising a total cohort of 1800 patients. Among them, 899 patients received WALANT (50.0%). Among the RCTs, patient satisfaction was found to be higher in patients receiving WALANT (SMD 1.01, 95% CI 0.11-1.92, p = 0.03, I² = 93%). Post-operative pain was found to be non-significant using WALANT (95% CI -3.72-0.03, p = 0.10, I² = 99%), as was operative time difference (95% CI -0.42-0.40, p = 0.96, I² = 0%).

CONCLUSION

The use of WALANT in elective hand surgery potentially results in higher satisfaction rates compared with anaesthesia with tourniquets. Post-operative pain and operation time were also found to be non-inferior in WALANT, but more robust studies are needed to verify these findings.

Wide-Awake Local Anesthesia No Tourniquet in hand surgery: A systematic review and meta-analysis

WALANT (Wide Awake Local Anesthesia No Tourniquet) has been widely implemented in hand surgery. We conducted a systematic review from 1979 to 2022, led by a team of anesthesiologist. Only randomized studies comparing WALANT to other types of regional anesthesia were included. The outcomes studied were pain, duration of the procedure, intraoperative bleeding, complications, and patient satisfaction. Twelve articles were included in the analysis. We found a reduction of 2.77 on the VAS (95% CI -3.79; -1.75, I² 93%) for intraoperative pain in the WALANT group. There was no significant difference (MD 0.79, 95% CI 95% -0.11; 1.69, I² 73%) for duration of surgery. Patient satisfaction was consistently high in the WALANT group. Intraoperative bleeding was minimal and not clinically relevant. Compared to other types of regional anesthesia in hand surgery, the WALANT technique decreases pain for the patients without increasing the length of surgery.

Clinically Important Pharmacologic Considerations for Wide-Awake Local Anesthesia No Tourniquet Hand Surgery

SUMMARY

Understanding the clinically important pharmacokinetics (what the body does to the drug) and pharmacodynamics (what the drug does to the body) of medications used in surgery will help surgeons use them more safely and effectively. The goal of this article is to provide an overview of these considerations for the 2 medications used in wide-awake local anesthesia with no tourniquet upper extremity surgery (ie, lidocaine and epinephrine) to establish a better understanding of lidocaine and epinephrine in tumescent local anesthesia, as well as adverse reactions and how to manage them.

The Outcome of the WALANT Technique in Primary Hand Flexor Tendons Repair

Introduction

Wide-awake local anesthesia and no tourniquet (WALANT) represents a revolutionary technique for hand surgeons who dismiss tourniquets and sedation. In this study, we present our experience with the WALANT technique in primary flexor tendon injuries of the hand.

Patient and methods

This prospective research was carried out on 30 patients undergoing hand primary, flexor tendon repair surgery. Flexor tendon injury zones 2, 3, 4, and 5 were included. WALANT was prepared and injected. The tendons were surgically managed by a cruciate single cross-stitched locked 4-strand technique. The pain was assessed using a visual analog scale (VAS) score. The range of motion (ROM) of affected fingers was assessed according to the Strickland evaluation system.

Results

There was a highly significant relationship between the patient's compliance with physiotherapy and obtained ROM of the affected finger with a P value <0.001. During injection of WALANT solution, 4 cases (13.3%) had no pain, 25 cases (83.3%) had mild pain (score 1-4), and 1 case (3.3%) had moderate pain (score 5-7).

Conclusion

WALANT provides an optimal bloodless and comfortable field with an opportunity to assess the strength of tendon repair, gapping or triggering and managing them intra-operatively.

Reevaluating the epinephrine myth: A comprehensive review

ABSTRACT

The combination of local anesthetic drugs with epinephrine has conventionally been contraindicated in acral regions due to concerns of potential necrosis caused by compromised blood flow. However, this belief has been challenged since 2001, when studies demonstrated the safety and effectiveness of the combination. This review aims to analyze reported cases of acral area necrosis following the use of local anesthesia with epinephrine since 2001. A thorough search was conducted on PubMed and Google Scholar using specific keywords to identify articles reporting acral area necrosis caused using local anesthesia and epinephrine. Our search yielded eight publications describing a total of 13 cases of ischemic events in acral areas. These cases involved finger necrosis (five cases), scrotal skin necrosis (two cases), and eyelid necrosis (six cases), following the injection of a combination of epinephrine and lignocaine. The majority of affected patients were female who underwent surgical intervention and reconstruction. The use of epinephrine in local anesthesia offers significant advantages and is generally safe for acral areas. However, the risk of necrosis cannot be entirely eliminated, particularly in patients with compromised vascular function. Adhering to proper guidelines and selecting suitable patients can help mitigate the risk. Phentolamine serves as a potential rescue agent if vascular compromise occurs. Precautionary measures must be taken when using this combination in high-risk patients.

Self-induced Hot Water Finger Burn Trying to Get Feeling Back after Ropivacaine Block

This case report is about a patient with self-induced hot water burns several hours after an infraclavicular block with ropivacaine for a scaphoid fracture operation. This patient was honest about what happened. However, some patients are too embarrassed to admit what they did to themselves. The injury may be misdiagnosed by the emergency department physician or by the surgeon because the history is incomplete. The resulting burn, which can lead to fingertip loss when severe, can be erroneously misdiagnosed as an ischemic injury after lidocaine with epinephrine local anesthesia. Most hand surgeons have seen ischemic finger injuries the morning after failed finger replantation. Acutely ischemic fingers from arterial insufficiency do not have parallel hot water burn lines, reactive hyperemia at the base of the burn, or burn blisters at the fingertips. The purpose of this article and its video is to help physicians and nurses recognize the three signs of self-induced hot water finger burns after local anesthesia: (1) a parallel hot water line in the fingers at the proximal burn level; (2) reactive hyperemia just proximal to the burn line; (3) burn blisters in the submerged fingertips. When seeing postoperative patients with these signs, the examining clinician may tactfully ask: "Did you try to get the feeling back in your fingers by warming them?" It is hoped that the patient may then reveal that he tried warming the finger in water, and that may lead to the truth that the water was indeed too hot.

Current Trends in Use of Epinephrine in Hand Surgery

BACKGROUND

Epinephrine use during hand surgery has been stigmatized due to a fear of digital necrosis. Clinical experience in the past 2 decades has shown epinephrine in local anesthetic to be safe. We sought to analyze the use of epinephrine among hand surgeons and identify variables associated with it.

METHODS

A deidentified 21-question survey was distributed via email to the 914 and 415 members of the American Association for Hand Surgery and the Canadian Society for Surgery of the Hand, respectively. Questions included residency type, years of practice, practice setup/ownership, practice leadership, usage of epinephrine, availability of reversal agents, and reasons for or against usage.

RESULTS

Of 188 responders, 170 (90%) used epinephrine in local anesthetic for hand surgery procedures. By nationality, 100% (43) of Canadian surgeons and 89% (108) of US surgeons use epinephrine (P = .01). Among surgeons with practice ownership, 88% (102) used epinephrine compared with 93% (85) of those surgeons that we employed (P = .28). Comparing surgeons with teaching responsibilities versus those without training responsibilities showed that surgeons who did not teach used epinephrine at a higher rate (87% vs 98%, P = .04). In addition, plastic surgery-trained surgeons (111) used epinephrine in 97.2% of cases while orthopedic surgery-trained surgeons (57) used epinephrine in 80.2% of cases (P = .0003). No difference was found when examining the use of epinephrine and surgeon age (P = .28).

CONCLUSIONS

Most respondents believe that epinephrine is safe. Training background, location, and practice setup are significant factors in the use of epinephrine, whereas practice ownership and physician age are not major factors.

Low-Concentration Brachial Plexus Block

PURPOSE

We devised a low-concentration brachial plexus block (LCBB) that allows for intraoperative, active motion by blocking only sensory nerves. This study evaluated the efficacy of the LCBB.

METHODS

Thirty-eight patients (14 men and 24 women; mean age, 60.0 years) underwent surgery with the LCBB. An ultrasound-guided supraclavicular brachial plexus block with 30-40 mL of 0.6 mg/ml ropivacaine hydrochloride hydrate was performed approximately 2 hours before starting the surgery. A local anesthetic (LA) was administered as a local infiltration if the intraoperative pain relief was locally insufficient. The surgery was performed using a tourniquet as usual, which was released for approximately 1 minute when there was a requirement to check for intraoperative, active motion. We recorded the waiting time required between LCBB administration and surgery, the total surgery time, the total tourniquet time, the number of patients administered an LA, the total LA volume (1% lidocaine equivalent), and the muscle strength at intraoperative, active motion (evaluated by manual muscle testing and categorized as ≥grade 4 or ≤grade 3).

RESULTS

The mean waiting time was 137.0 minutes, the mean surgery time was 124.6 minutes, and the mean tourniquet time was 70.6 minutes. In 2 patients, the anesthetic effect was not achieved, and we switched to other methods of anesthesia (1 patient was switched to an intravenous, regional anesthesia; 1 patient was switched to a standard brachial plexus block). Excluding those 2 cases, the mean LA volume was 8.7 mL among 22 cases (61.1%), and 33 cases (91%) had manual muscle testing of ≥grade 4. In 36 of 38 cases (94.7%), surgery could be performed by LCBB.

CONCLUSIONS

Although an LCBB may require additional LA, it is a useful anesthesia method that allows intraoperative active motion and tourniquet use.

Wide Awake Local Anesthetic No Tourniquet in Hand and Wrist Surgery: Current Concepts, Indications, and Considerations

Background

Traditionally, the use of a pneumatic arterial tourniquet was requisite for safe and effective surgery of the hand. The use of arterial tourniquets necessitates the use of regional or general anaesthesia. Wide-awake local anaesthetic no tourniquet (WALANT) has emerged as a novel technique to overcome the limitations of tourniquet use in conjunction with regional/general anaesthesia. This review aimed to examine the safety and effectiveness of WALANT and provide guidance for surgeons with limited WALANT experience.

Methods

A literature review of MEDLINE was performed up to March 2021 to identify all articles related to the use of WALANT in hand surgery. Any article reporting original data related to the use of WALANT was eligible for inclusion.

Results

A total of 101 articles were identified through database searching. Of these, 79 met full inclusion criteria and described the use of WALANT in 19 elective and trauma procedures. Current data suggest that WALANT is safe and effective for use in a range of procedures.

Conclusions

WALANT surgery is increasing in popularity as evidenced by the variety of surgical indications reported in the literature. There is limited comparative data on the cost-effectiveness of WALANT compared to conventional methods. Current data suggest that WALANT is safe, better tolerated by patients and associated with direct and indirect cost savings.

A prospective, comparative study of the analgesic effect between the WALANT technique and local anesthesia associated with sedation for hand surgery

PURPOSE

The primary objective of this study was to compare the WALANT (wide awake, local anesthesia, no tourniquet) technique with local anesthesia associated with sedation in relation to pain intensity for minor hand surgical procedures. The secondary objective was to evaluate the need for analgesic complementation.

METHODS

A prospective, randomized, comparative, and clinical study was carried out. The sample size in each group was determined after statistical evaluation of the results of a pilot project. The participants were allocated to one of two groups; those in group 1 were submitted to the WALANT technique, and those in group 2, to local anesthesia associated with sedation, for elective surgery. The surgical procedures were carpal tunnel syndrome, De Quervain's tenosynovitis, synovial cyst, finger cyst, and trigger finger. Pain intensity, need for complementation and evolution to complex regional pain syndrome were evaluated.

RESULTS

There was no difference between groups in pain intensity after WALANT and need for intraoperative complementation. There was no significant difference in the amount of opioid applied postoperatively between the groups. There was no difference between groups regarding comfort during surgery. There was no difference in adverse effects and complications between the groups. Hematoma was the most frequent adverse event. No severe adverse events were observed.

CONCLUSIONS

The WALANT technique promoted an analgesic effect similar to that of local anesthesia associated with sedation, without increasing adverse effects.

Wide-awake surgery in orthopaedics: "Scoping review"

INTRODUCTION

The anaesthetic modality "wide-awake" or "WALANT" (wide awake local anaesthesia not tourniquet) is based on the combination of a local anaesthetic with a vasoconstrictor to reduce bleeding during surgery and to avoid the use of a pneumatic tourniquet. The combination of 1% lidocaine together with 1:100,000 epinephrine is the most commonly used formula. The objective of this work is to carry out a review of the literature about this anaesthetic modality in the field of orthopaedic surgery and traumatology.

METHODS

PubMed and Embase databases were consulted with clearly defined operators. Two independent searches were conducted by two investigators, which were combined. Experimental, observational comparative studies, descriptive studies with n> 5 cases and cost studies were included. The individual results of the included studies are described.

RESULTS

A total of 8794 entries were collected of which a total of 36 studies were included in the review. A large number of these studies have been published since 2010 and refer almost entirely to hand surgery, with multiple indications applied. There is heterogeneity regarding the type of study design and variables studied, among others. In addition, there is a disparity when defining the methodology of the WALANT technique between the different studies.

CONCLUSIONS

This is the first comprehensive and reproducible review of the current state of the WALANT modality. There is great heterogeneity in terms of the study populations, the different comparators, variables studied between the different studies and a lack of precise details regarding the WALANT technique.

Thinking Outside the Operating Room: Guidance on Designing a Safe and Effective Minor Procedure Room

The minor procedure room (MPR) offers numerous advantages over the traditional operating room for performing many common hand surgeries. MPRs require less space, are subject to more practical architectural design standards, and facilitate more judicious use of disposable materials and unnecessary instruments than common hand surgeries. MPRs reduce costs to the system and patient at every step of the surgical workflow and improve efficiency by removing preoperative and postoperative monitoring requirements. Hand surgeons sometimes face resistance when attempting surgery in MPRs, often because of confusion about their design characteristics and capabilities. This article aims to clarify many of the major requirements for establishing an MPR and provide a guide to hand surgeons for performing safe, efficient surgery outside the operating room.

Digital ischemia after lidocaine with epinephrine injection in a patient with primary Raynaud's phenomena

Lidocaine with epinephrine is ubiquitous in hand procedures. Although existing literature supports the overall safety of this, significant physiologic changes accompanying epinephrine can disproportionately affect vascularly compromised patients, such as in Raynaud's phenomenon. The literature is reviewed and a case presented regarding the dangers of epinephrine injection in this population.

Outcomes After Flexor Tendon Injuries in the Pediatric Population: A 10-Year Retrospective Review

Background: Pediatric outcomes after flexor tendon repairs are variable, and evidence in the literature remains scarce. Methods: Repair of pediatric flexor tendon injuries was reviewed over a 10-year period (2005-2015). Data collection consisted of patient demographics, injury characteristics, anesthetic choice, repair technique, rehabilitation protocol, American Society for Surgery of the Hand Total Active Motion (TAM) scores, and complications. Results: There were 109 patients included in our study, with a total of 162 digits injured and 235 flexor tendon injuries. The mean age was 12 ± 4.6 years. The small finger (48 of 162; 30%) and the flexor digitorum profundus tendon (126 of 235) were the most commonly injured. The mechanism of injury was mainly from a knife (46 of 109; 42.2%) in zone II (82 of 159; 52%). Injuries were mostly repaired under general anesthetic (61 of 104; 56%). The Kessler technique was the predominant repair mechanism (111 of 225 repairs; 49%). Most patients (103 of 109; 95%) had excellent or good TAM scores with 5 postoperative ruptures reported. The most common complication was stiffness (17 of 121 complications; 14%), with most patients having no complications ( 74 of 109 patients; 68%). Patients were commonly immobilized (mean 8.4 ± 10.3 weeks) with a splint (93 of 109; 85%). There were 85 patients who followed a postoperative rehabilitation protocol for 12 ± 18 weeks. Patient demographics, time of repair, injury characteristics, anesthetic choice, and rehabilitation protocol were not significantly correlated with TAM scores or complication rates. Conclusions: Pediatric tendon injuries have good outcomes with no predictive factors identified. Surgical repairs performed under local anesthetic have similar outcomes without increased rates of complications, but remain underused in the pediatric population.

Current Evidence Involving WALANT Surgery

Wide-awake local anesthesia no-tourniquet (WALANT) surgery is an attractive option for hand surgeons, particularly during resource-scarce periods, as it eliminates dependence on main operating rooms or hospital-based procedures. The limited prepping or draping used for WALANT field sterility is as effective, if not more effective, than standard sterile prepping or draping. Patient anxiety surrounding WALANT surgery is similar to or less than that of general or local anesthesia with or without tourniquet. Patients use the same or lower amounts of postoperative narcotics after WALANT as compared to after the other anesthetic methods. Wide-awake local anesthesia no-tourniquet surgery saves significant costs for the same surgeries when performed under general or local anesthesia with or without tourniquet. There are very few complications associated with the WALANT method of anesthesia; rare case reports include vasovagal syncope and cardiac arrhythmia due to inadvertent intravascular injection of epinephrine.

The what, why and when of wide awake local anaesthesia no tourniquet surgery

Wide awake local anaesthesia no tourniquet, also known as WALANT, is the practice of performing surgery under local anaesthetic in the absence of a tourniquet. This technique uses the vasoconstrictive effects of adrenaline and the local anaesthetic effects of lignocaine to establish a Bier block with haemostatic control. Permitting active patient participation intraoperatively, wide awake local anaesthesia no tourniquet surgery improves patient compliance with rehabilitation and yields higher patient satisfaction. With reduced cost and equipment requirements, this method improves accessibility for patients and productivity for healthcare institutions. This is of particular benefit within the current COVID-19 climate, as wide awake local anaesthesia no tourniquet technique provides a means of overcoming restrictions to theatre access and anaesthetic support. This review delves into the current uses of wide awake local anaesthesia no tourniquet surgery, outlining the initial conception of the practice by Canadian surgeons. The advantages and disadvantages are considered, and potential future applications of this technique are discussed.

Comparison of 2% mepivacaine and a solution of 2% lidocaine/epinephrine administered for median and ulnar nerve blocks in horses with naturally occurring forelimb lameness

OBJECTIVE

To compare a 2% lidocaine solution containing 5 μg/ml (1:200 000) epinephrine with 2% mepivacaine for reducing lameness in horses after use in proximal nerve blocks.

STUDY DESIGN

Experimental randomized crossover.

ANIMALS

Six adult horses with naturally occurring forelimb lameness.

METHODS

Horses were evaluated using an inertial gait sensor system. Lameness was measured as a vector sum (VS). Following baseline lameness examination, median and ulnar nerve blocks were performed with lidocaine/epinephrine (0.5 mg epinephrine added to 50 ml of 2% lidocaine immediately prior to administration) or an equal volume of 2% mepivacaine. Horses were trotted at 5 min and then at 30 min intervals for 150 min. After 24 h, nerve blocks were repeated using the other local anesthetic. Data were evaluated using linear models.

RESULTS

The reduction in the VS did not differ after nerve blocks with lidocaine/epinephrine or mepivacaine (P = .791). Mean time to VS <8.5 mm (n = 5) was 5 and 9.6 min for lidocaine/epinephrine and mepivacaine, respectively. For one horse, VS was not reduced to <8.5 mm with either treatment (this horse had the highest VS before treatments were administered). The decrease in VS to <8.5 mm lasted for 150 min in both treatment groups.

CONCLUSION

The outcomes of the median and ulnar nerve blocks performed with 2% lidocaine with epinephrine did not differ from blocks performed with 2% mepivacaine.

CLINICAL RELEVANCE

Two percent lidocaine with epinephrine may serve as an adequate replacement for proximal nerve blocks when mepivacaine is unavailable.

Assessment of Dilute Epinephrine and Mechanical Pressure for Prevention of Feline Postoperative Scrotal Hematoma: A Randomized Controlled Trial

To determine whether two immediately postoperative preventive procedures, dilute epinephrine (1:400,000) as a scrotal wash or application of controlled mechanical pressure to the scrotum, reduce the risk or severity of scrotal hematoma following routine castration. Male cats with two descended testicles presenting to Midwestern University's Trap Neuter Return program were eligible for inclusion. Cats were assigned via block randomization to control, dilute epinephrine wash, or controlled mechanical pressure groups. For the epinephrine group, 0.2 ml (0.008 mg) of epinephrine diluted with sterile saline was instilled inside the scrotum. In the case of mechanical pressure, a broad-based clip generating less than 0.5 kg of pressure was applied for 10 minutes. Cats were evaluated for scrotal hematoma and the need for treatment by a veterinarian blinded to treatment group. Multivariable logistic regression was used to determine if the incidence of scrotal hematoma or scrotal hematoma requiring treatment was different between groups while controlling for other variables. There were 276 cats with a median age of 30 months (IQR 12,48) and a mean weight of 3.5 kg (SD 1.2). Scrotal hematomas were noted in 15 of the 92 (16%) control cats, as compared with 12 of the 92 (13%) epinephrine and nine of the 92 (10%) pressure cats. Treatment was required for 10 (67%) control, six (50%) epinephrine, and three (33%) pressure hematomas. Regression demonstrated a decreased risk of scrotal hematoma requiring treatment for cats in the pressure group (OR = 0.2, P = .044) controlling for weight (OR = 2.2, P = .006) and surgical duration (OR = 1.1, P = .026). Weight was the only significant variable for the presence of scrotal hematoma (OR = 2.2, P < .0001). Controlled mechanical pressure applied immediately after routine castration can help decrease the proportion of scrotal hematomas that require treatment.

Plate osteosynthesis of single metacarpal fracture: WALANT technique is a cost-effective approach to reduce postoperative pain and discomfort in contrast to general anesthesia and wrist block

BACKGROUND

The WALANT (wide-awake local anesthesia with no tourniquet) technique was based on local infiltration of lidocaine and epinephrine. This technique has rapidly gained popularity in recent years and can perform most hand operations. This study aimed to investigate the time spent on anesthesia and operation and perform an economic analysis among general anesthesia, wrist block with a tourniquet, and the WALANT technique for the internal fixation of metacarpal fractures.

METHODS

We retrospectively reviewed all the single metacarpal fractures managed with the same procedure, open reduction, and internal fixation with the plate between January 2015 and December 2019. They were divided into three groups according to the method of anesthesia: (1) general anesthesia (GA group), (2) wrist block with a tourniquet (WB group), and (3) WALANT technique (WALANT group). We collected and analyzed patient demographic data, perioperative or postoperative complications, number of hospital days, and postoperative functional recovery assessment.

RESULTS

A total of 63 patients met the inclusion criteria, including 24 in the GA group, 28 in the wrist block group using a tourniquet, and 11 in the WALANT group. There were no complications during the operation and follow-up in each group. The GA group had an average of 32.8 min of anesthesia time, significantly longer than the other two groups. However, there is no significant difference regarding surgical time among the presenting three groups. The discomfort of vomiting and nausea after surgery occurred in 20 patients in the GA group (38.1%). Nevertheless, there was no postoperative vomiting and nausea present in both the WB and WALANT groups. Most patients achieved full recovery of pre-injury interphalangeal and metacarpophalangeal motion at the final assessment of functional recovery.

CONCLUSIONS

The patients undergoing metacarpal fixation surgery under WALANT or WB had significantly less anesthesia time and postoperative vomiting and nausea. Moreover, there was no difference in surgical time and intraoperative complications. The time-related reduction improved the utilization of the operation room for additional cases. The reduction of the preoperative examination, anesthesia fee, postoperative recovery room observation, and hospitalization can effectively reduce medical costs. Furthermore, the WALANT group is more acceptable because of no tourniquet, which commonly causes discomfort.

Use of local anesthetics with an epinephrine additive on fingers and penis - dogma and reality

Epinephrine supplements in local anesthetics are regularly used for surgery in areas with terminal vessels. According to the pharmaceutical guidelines, the use of epinephrine as an additive to local anesthetics is contraindicated for these areas. This review provides an overview of the current scientific data as well as new clinical developments in various fields. It also reviews the current legal situation. A literature research was carried out to survey the current status of relevant data. Written inquiries to several German institutions (Institute for Quality and Efficiency in Health Care, National Association of Statutory Health Insurance Physicians, Center for Clinical Studies Tübingen, Federal Institute for Drugs and Medical Devices) were made to determine the legal situation. No evidence was found in the literature for a causal relationship between the use of epinephrine as a vasoconstrictor and necrosis of the finger or penis. Studies and reviews show that the use of local anesthetics with epinephrine on the fingers or penis is a safe procedure with many clinical and economic advantages. In routine clinical practice, the WALANT method (Wide Awake Local Anesthesia No Tourniquet) as well as the increasing incidence of skin tumors in acral areas has led to a tendency towards increasing use. However, its use is still legally contraindicated, and the pharmaceutical companies show no interest in supporting a drug study. Further clinical trials - regardless of the strength of the evidence - would not change the current legal contraindication.

Epinephrine one-per-mil tumescent solution in hand surgery: Review of experimental and clinical studies

One-per-mil epinephrine solution (1:1,000,000) injected as a tumescent has been used in several hand and upper-limb surgery cases as a substitute for tourniquet. However, reviews of its effectiveness are still lacking. A comprehensive review was conducted based on PubMed, Scopus, Science Direct, Cochrane Library, and Semantic Scholar database search of relevant studies using the keyword "one-per-mil." Studies not using the exact one-per-mil tumescent solution formula were excluded. The review of clinical studies was conducted according to PRISMA guidelines. Epinephrine and the hydrostatic vasocompressive effect created bloodless operative fields, with 100% experimental flap survival after ischemic insult. The technique was effective in creating bloodless operative fields in 36.3% of varied hand and upper-limb surgery cases and in fully awake surgery. Current studies show that one-per-mil tumescent solution is safe and effective, enabling use of tourniquet to be avoided.

Accidental digital epinephrine injection injury: a case of conservative management

The open access to epinephrine autoinjectors has resulted in an increased number of reports related to accidental injection into the digits. The appropriate management after accidental injection remains controversial. This study presents the first case in Saudi Arabia of a young man who accidentally injected epinephrine into the thumb and a literature review of the treatment options available. A 19-year-old man presented with accidental injection of 300 mcg of epinephrine into the volar pulp of his right thumb while treating an allergic reaction. The embedded needle was removed by countertraction and irrigation. The examination results were normal. The patient was discharged with prophylactic antibiotic and analgesia. Later, the puncture wound healed and vascularity and sensation remained intact. Conservative management and observation are advantageous in certain cases if vascular function is uncompromised. This case highlights the importance of education about the correct handling and administration of the epinephrine injection.

Application of WALANT technique for repairing finger skin defect with a random skin flap

BACKGROUND

Wide-awake local anesthesia no tourniquet (WALANT) technique has emerged among hand surgeons with other indications. Surgeries involving pedicled flap and revascularization are no longer used as contraindications. The present study aimed to evaluate the feasibility and merits of the WALANT technique in random skin flap surgery.

METHODS

From May 2018 to March 2019, 12 patients with finger skin defects repaired with random skin flaps were reviewed. Abdominal skin flaps or thoracic skin flaps were used to cover the wound. Both the fingers and the donor sites were anesthetized by the WALANT technique. A 40-mL conventional volume consisted of a mixture of epinephrine and lidocaine. A volume of 5 mL was injected at the distal palmar for nerve block, the other 5 mL was injected around the wound for hemostasis, and the remaining was injected at the donor site of flaps for both analgesia and hemostasis. Baseline data with respect to sex, age, side, type of finger, donor sites, flap size, dosage of anesthetics, usage of finger tourniquet, intraoperative and postoperative pain, hemostasis effect, operation time, Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH) score, and hospitalization expense, were collected.

RESULTS

All patients tolerated the procedure, and none of them needed sedation. Single finger skin defect in 8 patients and double finger skin defect occurred in 4 patients; 5 patients were repaired by abdominal skin flaps, and 7 patients were repaired by thoracic skin flaps. The good surgical field visibility was 91.7%. All flaps survived adequately, without necrosis, pulling fingers out, and other complications. The average visual analog scale (VAS) score of the maximal pain was 1.1 in fingers vs. 2.1 in donor sites during the operation. On postoperative day one, the average VAS score of the maximal pain in fingers and donor sites was 1.3 and 1.1, respectively. The average hospitalization expense before reimbursement of the whole treatment was 11% less expensive compared to the traditional method. The average QuickDASH score was 9.1.

CONCLUSIONS

Under wide-awake anesthesia, patients have the ability to control their injured upper extremities consciously, avoiding the complications due to pulling flap pedicles. With the merits of safety, painlessness, less bleeding, and effectivity, the WALANT technique in random skin flaps is feasible and a reliable alternative to deal with finger skin defect.

WALANT-Epinephrine injection may lead to short term, reversible episodes of critical oxygen saturation in the fingertips

INTRODUCTION

Although the WALANT technique's long-term safeness has been demonstrated in many studies, there are only few data investigating its short-term effects on tissue perfusion and oxygen levels. It was hypothesized that, temporarily, critical levels of tissue perfusion may occur.

METHODS

Seventeen patients, who were scheduled for different procedures in WALANT technique, were injected with 5-7 ml of 1% Articain containing 1:200,000 epinephrine at the finger base. Capillary-venous oxygen saturation, hemoglobin volume in the capillaries, and relative blood flow in the fingertips were recorded once per second by white light spectrometry and laser Doppler flowmetry before, during and after injection for an average of 32 min.

RESULTS

Clinically, no persistent tissue malperfusion was observed, and there were no postoperative complications. Capillary-venous oxygen saturation was reduced by ≥ 30% in seven patients. Critical levels of oxygen saturation were detected in four patients during 13 intervals, each lasting for 132.5 s on average. Oxygen saturation returned to noncritical values in all patients by the end of the observation period. Blood flow in the fingertips was reduced by more than 30% in nine patients, but no critical levels were observed, as with the hemoglobin. Three patients demonstrated a reactive increase in blood flow of more than 30% after injection.

CONCLUSIONS

Injection of tumescent local anesthesia containing epinephrine into finger base may temporarily cause a substantial reduction in blood flow and lead to critical levels of oxygen saturation in the fingertips. However, this was fully reversible within minutes and does not cause long-term complications.

Case reports and narrative fallacies: the enigma of black swans in dermatology

Narrative fallacy is a problematic heuristic that leads us to make inaccurate cause-effect relationships. They are a particular issue in case reports because of the limited scope of these papers, the perpetuated biases they proffer and the misperception of 'black swan' events. This article highlights the negative effects of these fallacies in dermatological practice through three case studies: the use of epinephrine with lignocaine at distal sites, the difference between once-daily and twice-daily application of topical steroids, and the effect of sterile gloves for skin surgery on infection rates. Awareness of the biases in case reports and the employment of metacognition may help us to avoid falling victim to narrative fallacies. Given the potential problems with this heuristic, Clinical and Experimental Dermatology (CED) utilizes case reports to further medical education and offer different clinical perspectives, rather than as a driver of medical knowledge.

Incorporating Office-Based Surgery Into Your Practice With WALANT

Office-based surgery (OBS) with wide-awake local anesthesia no tourniquet (WALANT) surgery is a safe and cost-effective care model that is convenient for patient and provider alike. Currently, the practice is growing, but in the majority of North America the ambulatory-care center is still the most common setting for hand surgery. This article discusses the practical issues of implementing OBS with WALANT including clinical setup and workflows for OBS, negotiating payor contracts, and managing liability.

A cost and efficacy analysis of performing arthroscopic excision of wrist ganglions under wide-awake anaesthesia versus general anaesthesia

Background

Arthroscopic excision has currently become popular for the treatment of wrist ganglions. The objective of this study was to evaluate the clinical outcomes and cost effectiveness of arthroscopic wrist ganglion excisions under Wide-Awake Local Anaesthesia No Tourniquet versus general anaesthesia.

Methods

We retrospectively reviewed patients who underwent arthroscopic ganglionectomy from April 2009 to October 2016 at our institute. They were separated into two groups according to anaesthesia techniques: general anaesthesia and Wide-Awake Local Anaesthesia No Tourniquet. We compared the clinical outcomes and cost-effectiveness of the two groups.

Results

Seventy-four patients were included. Both groups were matched with regard to the demographics and preoperative clinical assessments. We found no significant differences between groups in postoperative visual analog scale, modified Mayo wrist score, Disabilities of Arm, Shoulder and Hand score, recurrence, residual pain, or complications. Recurrence was found in five of 74 patients, one (4.3%) in the Wide-Awake Local Anaesthesia No Tourniquet group and four (7.8%) in the general anaesthesia group. One extensor tendon injury and four extensor tenosynovitis cases occurred in the general anaesthesia group. Regarding cost effectiveness, the mean operating time in the Wide-Awake Local Anaesthesia No Tourniquet and general anaesthesia groups were 88.7 ± 24.51 and 121.5 ± 25.75 min, respectively (p < 0.001). The average total costs of the Wide-Awake Local Anaesthesia No Tourniquet and general anaesthesia groups were €487.4 ± 89.15 and €878.7 ± 182.13, respectively (p < 0.001).

Conclusions

For arthroscopic wrist ganglion resections, both anaesthesia techniques were effective and safe regarding recurrence rates, complications, and residual pain. The most important finding of this study was that arthroscopic ganglionectomy under Wide-Awake Local Anaesthesia No Tourniquet was superior to that under general anaesthesia for cost-effectiveness.

Anesthetic and Analgesic Efficient of Regional Nerve Blockade in Otoplasty

AIM

The prominent ear is the most common congenital deformity of the external ear. Otoplasty is performed to correct the appearance of the prominent ear. This study was planned to compare the analgesic and anesthetic effects of local nerve blockade and local infiltration anesthesia in the otoplasties.

METHOD

Thirty-two patients who underwent otoplasty in both ears between February 2018 and March 2019 were included in the study. Three patients were excluded because they refused regional anesthesia. In the patients included in the study, only local infiltration anesthesia was applied to 1 ear and regional nerve blockade was applied to the other ear. Regional nerve blockade was applied to the study group; local infiltration anesthesia was applied to the control group. Surgical and anesthetic complications were recorded. The onset time, duration and severity of pain were followed. Numerical evaluation scale scores were used to evaluate pain levels.

RESULTS

It was observed that the first pain of the patients On the side where regional nerve block (RNB) anesthesia was applied after an average of 10.5 hours. On the other hand on the side where local infiltration anesthesia was applied; the pain was observed to start after an average of 3.5 hours. At the 6th and 12th hours postoperatively, the scores of the numerical evaluation scale were significantly lower in the study group than the control group (P < 0.05). At the 24th-hour pain score, the values were lower in the study group, but the difference was not significant between the groups (P > 0.05). In the regional anesthesia group, can develop such as difficulty in swallowing, weakness in the neck, weakness in the upper extremity, nausea, Horner syndrome; but all side effects resolve spontaneously within 6 to 12 hours.

CONCLUSION

The application of regional anesthesia in prominent ear surgical procedures can be considered as an alternative method to provide better quality preoperative anesthesia and better quality postoperative analgesia in patients.

Treatment and management strategies of onychomycosis

Onychomycosis is one of the most prevalent and severe nail fungal infections, which is affecting a wide population across the globe. It leads to variations like nail thickening, disintegration and hardening. Oral and topical drug delivery systems are the most desirable in treating onychomycosis, but the efficacy of the results is low, resulting in a relapse rate of 25-30%. Due to systemic toxicity and various other disadvantages associated with oral therapy like gastrointestinal, hepatotoxicity, topical therapy is commonly used. Topical therapy improves patient compliance and reduces the cost of treatment. However, due to poor penetration of topical therapy across the nail plate, research is focused on different chemical, mechanical and physical methods to improve drug delivery. Penetration enhancers like Thioglycolic acid, Hydroxypropyl-β-cyclodextrin (HP-β-CD), Sodium lauryl sulfate (SLS), carbocysteine, N-acetylcysteine etc. have shown results enhancing the drug penetration across the nail plate. Results with physical techniques such as iontophoresis, laser and Photodynamic therapy are quite promising, but the long-term suitability of these devices is in need to be determined. In this article, a brief analysis of the treatment procedures, factors affecting drug permeation across nail plate, chemical, mechanical and physical devices used to increase the drug delivery through nails for the onychomycosis management has been achieved.

Utility of local anesthesia for open carpal tunnel release in patients with psychiatric diagnoses

Purpose

Carpal tunnel release, one of the most commonly performed procedures in Veterans Affairs (VA) medical centers, is often performed under local anesthesia alone. In this patient population, there is an increased prevalence of psychiatric disorders. Our hypothesis is that there is no difference in operating time, request for sedation, or complications in the veteran population with or without a recognized psychiatric history.

Methods

A retrospective cohort study was performed at a VA medical center from January 2013 to January 2017 by the senior surgeon (E.S.L). Patients were divided into two groups: patients with no known psychiatric history (n = =33) and patients with an active psychiatric diagnosis (n = =25), including post-traumatic stress disorder, anxiety disorder, bipolar disorder, depression, substance abuse, or panic disorder. Primary endpoints included operation time, time in operating room, request for sedation, and complication rates.

Results

Fifty-nine percent of patients successfully underwent wide-awake hand surgery, while 41% requested sedation. Patients with no known psychiatric history had a 45.5% rate of requesting sedation compared to 36% in those with a psychiatric diagnosis. No patients converted from wide-awake surgery to sedation. There was no statistically significant difference in operation time, time in the operating room, need for sedation, or complication rate between all groups.

Conclusions

Wide-awake hand surgery is an excellent technique that can be safely used in patients with a history of psychiatric illness. Without the need for monitored anesthesia care, the cost for carpal tunnel releases done in military medical centers could decrease dramatically.

A comparison of the postoperative analgesic effectiveness of low dose caudal epidural block and US-guided dorsal penile nerve block with in-plane technique in circumcision

BACKGROUND

Circumcision can be performed under sedo-analgesia, general anesthesia, or regional anesthesia. It may cause serious postoperative pain and patients often require additional analgesia. Dorsal penile nerve block (DPNB) and caudal epidural block are commonly used regional anesthesia methods to provide effective postoperative pain control in circumcision.

OBJECTIVE

In this prospective observational study, we aimed to investigate the postoperative analgesic efficiency of DPNB with the ultrasound (US)-guided in-plane technique and single-dose caudal epidural block in circumcision.

STUDY DESIGN

Male patients aged 4-12 years in the ASA I-II group, who were scheduled for circumcision, were included in the study. A caudal epidural block or US-guided DPNB with the in-plane technique was administered under general anesthesia before the operation. Postoperative pain was evaluated using the Children's Hospital Eastern Ontario Pain Scale (CHEOPS) and Faces Pain Scale-Revised (FPS-R). Postoperative analgesic need and parental satisfaction were also noted.

RESULTS

There were 140 patients in our study. The number of patients receiving a caudal block (n = 70) and DPNB block (n = 70) was equal. Side effects were only seen in five patients in the caudal group. No side effects were seen in patients in the DPNB group. Analgesics were required in 3.6% of the patients in the caudal group and none of the patients in the DPNB group postoperatively. CHEOPS mean scores in the caudal block group were found to be statistically significantly higher than in the penile block group. FPS-R 24th^. hour mean score was statistically significantly higher in the caudal block group (P < 0.001). Postoperative parental satisfaction in the penile block group was found to be statistically significantly better than in the caudal block group (P = 0.028).

DISCUSSION

This study demonstrated that DPNB conducted with the US-guided in-plane technique was more effective than caudal block in providing postoperative analgesia. The parental satisfaction was also higher, and no side effect was seen in the DPNB group.

CONCLUSION

DPNB conducted with the US-guided in-plane technique is a simple and safe regional anesthesia method used to provide effective postoperative analgesia for male circumcision. Complications related to DPNB can be prevented with the help of the real-time imaging provided by ultrasound.

Effects of vasoconstrictor use on digital nerve block: systematic review with meta-analysis

Conventionally, the association of local anesthetics with vasoconstrictors is avoided at extremities due to the risk of ischemia. However, recent studies suggest that there is safety in the use of vasoconstrictors at extremities. Thus, we sought to evaluate the effectiveness and safety of vasoconstrictor use combined with local anesthetics in digital nerve block compared to the use of anesthetics without vasoconstrictors, through a systematic review with meta-analysis of randomized clinical trials. Until May 2019 we searched MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov, and gray literature databases, without date or language restrictions. The keywords were the following: digital block, vasoconstrictor, and ischemia. We included randomized clinical trials in which there was the use of local anesthetics with associated or not with vasoconstrictors in digital blocks. In the primary variables, the occurrence of ischemic complications and the duration of anesthesia were analysed; in the secondary variables, the need for anesthetic reapplication, bleeding control, and latency were observed. Ten studies were included in this review. The occurrence of ischemia was not observed, regardless of the use of vasoconstrictors or not. The use of vasoconstrictors at a concentration of 1:100,000 or less was associated with longer anesthesia duration (P<0.00001), lower need for anesthetic reapplication (P=0.02), lower need for bleeding control (P=0.00006), and lower latency (P<0.00001). We could conclude that the use of vasoconstrictors associated with local anesthetics in digital block proved to be a safe and effective technique.

Tourniquet Use in Wide-Awake Carpal Tunnel Release

Background: Carpal tunnel syndrome is a common cause of upper extremity discomfort. Surgical release of the median nerve can be performed under general or local anesthetic, with or without a tourniquet. Wide-awake carpal tunnel release (CTR) (local anesthesia, no sedation) is gaining popularity. Tourniquet discomfort is a reported downside. This study reviews outcomes in wide-awake CTR and compares tourniquet versus no tourniquet use. Methods: Wide-awake, open CTRs performed from February 2013 to April 2016 were retrospectively reviewed. Patients were divided into 2 cohorts: with and without tourniquet. Demographics, comorbidities, tobacco use, operative time, estimated blood loss, complications and outcomes were compared. Results: A total of 304 CTRs were performed on 246 patients. The majority of patients were male (88.5%), and the mean age was 59.9 years. One hundred patients (32.9%) were diabetic, and 92 patients (30.2%) were taking antithrombotics. Seventy-five patients (24.7%) were smokers. A forearm tourniquet was used for 90 CTRs (29.6%). Mean operative time was 24.97 minutes with a tourniquet and 21.69 minutes without. Estimated blood loss was 3.16 mL with a tourniquet and 4.25 mL without. All other analyzed outcomes were not statistically significant. Conclusion: Operative time was statistically longer and estimated blood loss was statistically less with tourniquet use, but these findings are not clinically significant. This suggests that local anesthetic with epinephrine is a safe and effective alternative to tourniquet use in CTR. The overall rate of complications was low, and there were no major differences in postoperative outcomes between groups.

Surgical site infection leading to gangrene and amputation after ambulatory surgical care of an ingrown toenail: a case report

Background

Currently, the management of ingrown toenail (onychocryptosis) ranges from conservative medical management to surgical treatment. Surgical management is typically performed as an outpatient procedure due to it numerous advantages such as the simplicity of the technique and the low incidence of postoperative complications. The most common postoperative complications are recurrences and surgical site infections, whereas gangrene complicating a surgical site infection has been scarcely reported. We are reporting a rare complication following ambulatory surgery untimely requiring amputation.

Case presentation

A twelve-year-old boy was referred to our orthopedic surgical department for a surgical site infection complicating an initial surgical management of a left ingrown big toenail leading to a dry gangrene of the affected toe. The gangrene toe was amputated under peripheral nerve block and the patient was discharged home the same day on antibiotics, analgesics and with sessions of rehabilitation and psychological support planned. The postoperative course was uneventful at 6 months of follow-up.

Conclusion

The authors report this case to draw clinicians’ attention, especially wound care specialists, orthopedists and podiatrists to this rare but potentially debilitating disease.

A Cost and Efficiency Analysis of the WALANT Technique for the Management of Trigger Finger in a Procedure Room of a Major City Hospital

The “Wide Awake Local Anesthesia No Tourniquet” (WALANT) technique is gaining popularity in hand surgery owing to its benefits of reduced cost, shorter hospital stay, improved safety, and the ability to perform active intraoperative examinations. The aim of this study is to analyze the cost savings and efficiency of performing A1 pulley release for treatment of trigger finger using the WALANT technique in a major city hospital procedure room (PR) as compared with the standard tourniquet, operating room (OR) approach.

Is it safe to inject local anaesthetic with adrenaline into the pinna and external nose?

Adrenaline containing lidocaine preparations such as lignospan are routinely used in ear, nose and throat (ENT) care. Despite this, textbooks and internet resources warn against their use in peripheries, including the nose and ear. As a result, they are commonly avoided by other specialties, such as emergency medicine. This article reports on the findings of a review undertaken to assess the evidence of harm associated with using lignospan in the pinna and external nose. A literature search was carried out, and retrospective data were collected on all elective facial skin lesion surgery in the ENT department at the Great Western Hospital in Swindon between 2005 and 2015. Cases using lignospan in the pinna and nose were included. The literature search revealed no reports of ischaemic complications of the pinna or nose following use of lignospan, or similar preparation. Of the 1,409 cases collected, no ischaemic complications were recorded. The article concludes that adrenaline containing lidocaine preparations such as lignospan are safe for use in the pinna and nose, and should be considered for use in emergency departments.

Robust surgical approach for cutaneous neurofibroma in neurofibromatosis type 1

BACKGROUND

Cutaneous neurofibromas (cNF) are physically disfiguring, painful, and cause extensive psychologic harm in patients with neurofibromatosis type 1 (NF1). There is currently no effective medical treatment and surgical procedures are inaccessible to most NF1 patients globally.

OBJECTIVE

While research is underway to find an effective medical treatment for cNF, there is an urgent need to develop surgical approach that is accessible to all NF1 patients in the world with the skill set and equipment found in most general medical office settings. Here, we present a robust surgical approach to remove cNF that does not require sterile surgical field, utilizes accessible clinical equipment, and can be performed by any health care providers including family practitioners, and physician assistants.

METHODS

In a prospective case-series, patients with NF1 underwent this surgical procedure which removes multiple cutaneous neurofibromas. The Dermatology Life Quality Index was given to subjects before and after the procedure as surrogate for patient satisfaction.

RESULTS

83 tumors were removed throughout the body from twelve individuals. Examination at follow-up visits revealed well-healed scars without infection or adverse events including aberrant scarring. Patient satisfaction with the procedure was high with significant improvements in symptoms, daily activities, leisure, personal relationships, and treatment experience (P = 0.00062).

CONCLUSION

This study demonstrates a robust surgical approach to management cutaneous neurofibromas which can be accessed world-wide to individuals with NF1 and performed by a wide-variety of medical specialists with high clinical efficacy and patient satisfaction.
