Adoption of the Wide-Awake Local Anesthesia No Tourniquet Technique in Hand Surgery.

¼ Wide-awake local anesthesia no tourniquet (WALANT) technique featuring tumescent infiltration of lidocaine with epinephrine at the operative site has broad application in hand surgery including both soft-tissue and bone procedures.¼ The advantages of wide-awake anesthesia include high patient satisfaction, preserved intraoperative finger and wrist motion, cost-effectiveness, improved operating room efficiency, fewer opioids during recovery, and improved access to hand surgery, which may be performed in an office-based setting without the need for anesthesia personnel.¼ In properly selected patients, use of lidocaine with epinephrine in the hand and fingers is safe. Rare postprocedure digital ischemia may be effectively treated with phentolamine rescue.¼ Barriers to adopting wide-awake anesthesia may be overcome by educating resistant stakeholders, including hospital administrators, nurse leaders, and anesthesia colleagues, about the advantages of the WALANT method.¼ The risk of postoperative complications after hand procedures may be mitigated by using the wide-awake technique instead of regional anesthesia with sedation or general anesthesia.

The impact of WALANT anesthesia and office-based settings on patient satisfaction after carpal tunnel release: A patient reported outcome study.

HYPOTHESIS: Wide awake local anesthesia with no tourniquet (WALANT) and office-based procedures are used in hand surgery. There are limited literature data on patient satisfaction when comparing methods of anesthesia and location of surgery. METHODS: We conducted a retrospective single-surgeon study with patient reported satisfaction in three groups. We compared patient impressions of anesthesia type; WALANT vs locoregional anesthesia plus sedation. We also compared satisfaction in three surgery settings; office surgery vs hospital ambulatory minor procedure room vs main operating room. Group 1 office surgery patients had ultrasound guided surgery with WALANT. Group 2 main operating room surgery patients also had ultrasound guided surgery with WALANT. Group 3 main operating room patients had endoscopic surgery with sedation and a tourniquet. Each group had 30 patients with a minimum follow up of 2 months. We measured overall satisfaction, satisfaction with the organization of care, satisfaction with the administration of anesthesia, and satisfaction with the quality of anesthesia. We also collected secondary data on the resolution of the neuropathic symptoms. RESULTS: Procedures performed in an office-based setting showed higher rates of patient satisfaction when compared to the ambulatory day surgery setting. WALANT anesthesia also showed significantly higher rates of patient satisfaction on a numerical analog scale when compared to sedation based on, irrespective of the surgical setting. All patients had resolution of their neuropathic symptoms regardless of the technique performed. CONCLUSION: We found that carpal tunnel releases performed in an office-based setting produces superior patient satisfaction. WALANT anesthesia also provides improved patient satisfaction when compared to sedation and monitoring techniques, irrespective of the surgical setting and location. Carpal tunnel release with WALANT in an office-based setting is better for patient comfort and satisfaction, with no evidence of lesser clinical outcomes at a short term follow-up. LEVEL OF EVIDENCE: III.

Ten Questions About Wide Awake Local Anaesthesia No Tourniquet (WALANT) Surgery.

The aim of this review article is to provide many important tips and tricks for surgeons to start Wide Awake Local Anaesthesia No Tourniquet (WALANT) hand surgery in their practice. The massive cost reduction of this disruptive new approach will enable them to increase access to hand surgery for their patients who cannot afford unnecessary sedation or unnecessary sterility of the expensive main operating room environment. Evidence-based sterility will permit surgeons to move a lot of their surgery out of the main operating room to minor procedure rooms without a significant increase in infection rates. Important pointers on how to inject minimally painful local anaesthesia will have patients thinking the surgeon injector is a bit of a magician. WALANT enables surgeons to improve the outcomes of many hand surgery procedures. Level of Evidence: Level V (Therapeutic).

Important updates of finger fractures, entrapment neuropathies and wide-awake surgery of the upper extremity.

Hand surgery is rapidly changing. The wide-awake approach, minimum dissection surgery and early protected movement have changed many things. This is an update of some of the important changes regarding early protected movement with K-wired finger fracture management, simplification of nerve decompression surgery, such as elbow median and ulnar nerve releases, and some new areas in performing surgery with wide-awake local anaesthesia without tourniquet.

Creating an Outpatient, Local Anesthetic Hand Operating Room in a Resource-Constrained Ghanaian Hospital Builds Surgical Capacity and Financial Stability.

INTRODUCTION: Expanding surgical capacity is very difficult in resource-constrained countries. Financial input and additional physical operating room space are needed. The surgical patient volume exists, but the lack of operating room time causes postponement of cases. Hand surgery is particularly important as it improves patient function and allows for a timely return to the workforce after injury. Some hand surgery cases may be performed under local anesthesia with a very basic instrument set in a procedure room. This arrangement eliminates the need and financial burden of an equipped operating room and the need for an anesthesiologist. We hypothesized that performing hand surgery in a simple procedure room by a surgeon with knowledge of adequate local anesthesia could increase hand surgery capacity significantly in a low-income country. METHODS: This technique has been instituted at Komfo Anokye Teaching Hospital in Kumasi, Ghana, with the use of a single procedure room that was previously used for storage. A surgeon trained in performing wide-awake local anesthesia no tourniquet technique visited Komfo Anokye Teaching Hospital and provided lectures about hand surgery under local anesthesia and evidence-based sterility for 6 years. The number and type of cases performed in the procedure room were recorded for the first 11 months after it opened in 2017. RESULTS: For 11 months, use of this room had increased surgical capacity by 33 cases per month. Patient ages ranged from 2 months to 65 years. There have been 358 total cases performed, 240 of which were hand cases. This included washout of hand wounds (n = 87), tendon repair (n = 54) including a single tendon transfer, fracture pinning (n = 33), amputations (n = 24), trigger finger repair (n = 10), nerve repair (n = 6), congenital hand surgery (n = 4), and other (n = 22). Cost savings per case in the procedure room ranges from 500 cedis (US $100) to 2000 cedis (US $400). CONCLUSIONS: The simple procedure room runs more efficiently and is less costly compared with the main operating rooms. Although the case volume has increased surgical capacity significantly, costs to the hospital and patient have decreased. The hospital is reimbursed in a timely fashion for the procedures directly by the patient using this technique. The creation of a single procedure room for wide-awake local anesthesia no tourniquet hand surgery has helped address the issues of inadequate operating room space, time, and expense in resource-constrained Ghana.

Contemporary Approaches to Postoperative Pain Management.

LEARNING OBJECTIVES: After reading this article, the participant should be able to: 1. Describe the fundamental concepts of multimodal analgesia techniques and how they target pain pathophysiology. 2. Effectively educate patients on postoperative pain and safe opioid use. 3. Develop and implement a multimodal postoperative analgesia regimen. SUMMARY: For many years, opioids were the cornerstone of postoperative pain control, contributing to what has become a significant public health concern. This article discusses contemporary approaches to multimodal, opioid-sparing postoperative pain management in the plastic surgical patient.

Latest Advances in Wide Awake Hand Surgery.

Injection of tumescent local anesthesia should no longer be painful. WALANT anesthesia, strong sutures, a slightly bulky repair, intraoperative testing of active movement, and judicious venting of the A2 and A4 pulleys improve results in flexor tendon repair. WALANT K wire finger fracture reduction permits intraoperative testing of K wire stability with active movement to facilitate early protected movement at 3 to 5 days after surgery. WALANT can decrease costs and garbage production while increasing accessibility and affordability. Several surgeons have found no infection difference when the K wires are inserted with full operating room sterility versus field sterility.

The Canadian Model for Instituting Wide-Awake Hand Surgery in Our Hospitals.

Clinic-based hand surgery performed under local anesthetic has been steadily increasingly performed in Canada for 50 years. The drive for its development stems from the Canadian health care system's finite funding structure and resources. Benefits have extended far beyond cost and garbage reduction. It has resulted in greatly improving patient care by increasing comfort and safety with the elimination of sedation, the tourniquet, night surgery, and by improving access to care. This article details the rationale and development of clinic-based hand surgery from a Canadian perspective and provides tips and strategies for other centers looking to implement a similar clinic.

Wide Awake Tendon Transfers in Leprosy Patients in India.

Dr Akbar Khan began using the wide awake local anesthesia no tourniquet (WALANT) technique for leprosy tendon transfers in the summer of 2015 at the Damien Foundation Hospital in Nellore, India. This article summarizes his first 18 months of experience and describes 5 of his operations. He found that WALANT provides effective anesthesia with good visibility for leprosy tendon transfers. WALANT permits economically disadvantaged leprosy patients to afford the surgery. All of the leprosy patients who have undergone WALANT tendon transfers in this series would like the same technique for their next tendon transfers.

How Much Volume of Local Anesthesia and How Long Should You Wait After Injection for an Effective Wrist Median Nerve Block?

BACKGROUND: Many surgeons and emergentologists use non-ultrasound-guided wrist nerve blocks. There is little evidence to guide the ideal volume of local anesthesia or how long we should wait after injection before performing pain-free procedures. This pilot study examined time to maximal anesthesia to painful needle stick in 14 volunteer participants receiving bilateral wrist blocks of 6 versus 11 mL of local. METHODS: One surgeon performed all 14 bilateral wrist median nerve blocks in participants who remained blinded until after bandages were applied to their wrist. No one could see which wrist received the larger 11-mL volume injection versus the 6-mL block. Blinded sensory assessors then measured perceived maximal numbness time and numbness to needle stick pain in the fingertips of the median nerve distribution. RESULTS: Failure to get a complete median nerve block occurred in seven of fourteen 6-mL wrist blocks versus failure in only one of fourteen 11-mL blocks. Perceived maximal numbness occurred at roughly 40 minutes after injection, but actual numbness to painful needle stick took around 100 minutes. CONCLUSIONS: Incomplete median nerve numbness occurred with both 6- and 11-mL non-ultrasound-guided blocks at the wrist. In those with complete blocks, it took a surprisingly long time of 100 minutes for maximal anesthesia to occur to painful needle stick stimuli to the fingertips of the median nerve distribution. Non-ultrasound-guided median nerve blocks at the wrist as described in this article lack reliability and take too long to work.

Conceptual origins, current practice, and views of wide awake hand surgery.

This article reviews historical background, essential practice principles, and the new emerging area of wide awake hand surgery. It outlines the reasons that wide awake, local anaesthesia, no tourniquet surgery has emerged so quickly in the last 10 years over the world. I explain the origin of the concepts and some of the challenges of getting the technique accepted; in particular, the debunking of the myth of epinephrine danger in the finger. I review the most recent developments in several operations in this rapidly changing field of the tourniquet-free approach. Finally, this review includes speculations on the future of this technique.

[Time to bury the adrenaline-myth!--Safe use of adrenaline anesthesia in hand surgery and orthopedics]. / Dags att begrava adrenalin-myten! - Säkert bruk av adrenalinbedövning inom handkirurgi och ortopedi.

The epinephrine myth originated in the 1940s, when acidic (pH 1) procaine-epinephrine was injected into fingers, causing finger necrosis. Today, level 1 evidence exists for the safe use of epinephrine in fingers. The ability to use lidocaine-epinephrine in hand surgery and orthopedics eliminates the need for a tourniquet, or "bloodless field". Surgery using Wide Awake, Lidocaine-epinephrine Anesthesia, No Tourniquet (WALANT) reduces patient discomfort, facilitates patient participation in surgery, improves safe outcomes following reconstructions and greatly reduces the cost of medical care. Furthermore, patients regarded as high-risk can be safely treated without risk of cardiac or pulmonary side effects. In this manuscript, the background of the epinephrine myth is described, as well as recommended use of WALANT in hand surgery and orthopedics.

Wide-awake extensor indicis proprius to extensor pollicis longus tendon transfer.

This article provides video and narration to describe the technical details of how to inject local anesthesia and perform the extensor indicis proprius to extensor pollicis longus tendon transfer in patients with wide-awake local anesthesia and no tourniquet. Lidocaine for anesthesia and epinephrine for hemostasis are the only 2 medications given to the patient. Sedation and the tourniquet are not required. Wide-awake patients are comfortable, cooperative, and educable, and are able to help the surgeon set the correct tension for the transfer. They flex and extend the thumb before the skin is closed to make sure the transfer is not too tight or too loose. It helps that they remember seeing the thumb move nicely during the surgery when they are in postoperative hand therapy.

Minimizing the pain of local anesthesia injection.

BACKGROUND: Local anesthetic injection is often cited in literature as the most painful part of minor procedures. It is also very possible for all doctors to get better at giving local anesthesia with less pain for patients. The purpose of this article is to illustrate and simplify how to inject local anesthesia in an almost pain-free manner. METHODS: The information was obtained from reviewing the best evidence, from an extensive review of the literature (from 1950 to August of 2012) and from the experience gained by asking over 500 patients to score injectors by reporting the number of times they felt pain during the injection process. RESULTS: The results are summarized in a logical stepwise pattern mimicking the procedural steps of an anesthetic injection-beginning with solution selection and preparation, followed by equipment choices, patient education, topical site preparation, and finally procedural techniques. CONCLUSIONS: There are now excellent techniques for minimizing anesthetic injection pain, with supporting evidence varying from anecdotal to systematic reviews. Medical students and residents can easily learn techniques that reliably limit the pain of local anesthetic injection to the minimal discomfort of only the first fine needlestick. By combining many of these conclusions and techniques offered in the literature, tumescent local anesthetic can be administered to a substantial area such as a hand and forearm for tendon transfers or a face for rhytidectomy, with the patient feeling just the initial poke.
