INTRODUCTION: The WALANT (Wide Awake Local Anaesthesia No Tourniquet) technique has rapidly gained popularity. The advantages are often described, whereas information about complications is rare. Therefore, we followed up on our own patients regarding complications.Patients and Method Between January 2013 und June 2017, the complications experienced by one single surgeon were evaluated. The study included all elective (n = 195) and acute (n = 90) surgical procedures performed in WALANT. Minimum age of the patients was 18 years. All patients received Articaine 1 % and Suprarenine (1:200.000). Different volumes were injected with a minimum delay to surgery of 30 minutes. Complications were identified retrospectively by evaluation of patient files and a survey via telephone using a standardised questionnaire. Mean follow-up was 73 weeks.
RESULTS: In 285 patients, there were 13 (4.6 %) complications. After injection of 16 ml of Articaine/Suprarenine, one patient had coronary symptoms, which ceased when two puffs of nitroglycerin spray were given. In one patient with a neurovascular injury in the palm, a bloodless field could not be obtained. A short tourniquet time was necessary for exploration. In one patient undergoing flexor tendon tenolysis, there was a need to convert to general anaesthesia with tourniquet because there was insufficient vasoconstriction due to marked scar tissue. One patient had an erythema around the injection site for a prolonged time, two had extensive erythema on the dorsum of the hand and seven patients reported swelling of the hand that lasted more than one week.
SUMMARY: The WALANT method is safe. Perioperative complications are rare. Nevertheless, there are some disadvantages that should be considered.Vascular injuries, especially in fingers, are to be monitored closely regarding perfusion, and the off-label use should be remembered. Also, caution should be exercised in patients with cardiac disease. Larger injuries may need a short tourniquet time. Tissue that was operated on before does not always seem to be suitable for the technique as diffusion may be compromised. In rare cases, patients may suffer from prolonged erythema or swelling. Generally, patients should be evaluated for suitability to an operation in local anaesthesia.
