How safe is WALANT surgery?

Wide Awake Local Anaesthesia No Tourniquet (WALANT) is an increasingly popular technique for performing hand and upper limb surgery. It allows procedures to be carried out without general anaesthesia or a tourniquet, using only local anaesthetic with adrenaline to numb the area while the patient remains fully awake.

As the technique gains wider use in orthopaedics and plastic surgery, particularly for hand and wrist procedures, patients often ask how safe WALANT is compared to traditional methods. Overall, evidence and clinical experience suggest it is a safe and well-tolerated approach for suitable procedures.

What is WALANT and how does it work?

WALANT involves injecting a combination of local anaesthetic and adrenaline directly into the surgical site. The anaesthetic blocks pain while the adrenaline constricts blood vessels, limiting bleeding and removing the need for a tourniquet. This enables the surgeon to operate in a dry field without causing discomfort to the patient.

Common procedures performed under WALANT include:

Carpal tunnel release
Trigger finger release
Dupuytrens contracture
Removal of ganglions or cysts
Some fracture fixations

What are the safety advantages of WALANT?

WALANT has several safety benefits compared to traditional techniques:

Avoids general anaesthesia: Reduces risks linked to sedation or intubation, particularly in older adults or those with underlying health conditions
No tourniquet: Improves patient comfort and reduces complications from prolonged compression
Fewer systemic side effects: As the anaesthetic is localised, patients are less likely to experience nausea or grogginess after surgery
Real-time feedback: The patient can move the hand during surgery, helping the surgeon confirm tendon or joint function immediately
Lower risk of bleeding: The use of adrenaline reduces bleeding during the procedure without the need for other agents

Is adrenaline safe to use in the hand?

Historically, there were concerns about using adrenaline in the fingers due to the risk of reduced blood flow and tissue damage. However, modern studies and clinical evidence show that when used in safe concentrations and proper technique, adrenaline in WALANT procedures does not increase the risk of finger ischaemia or necrosis.

Surgeons using WALANT are trained to apply the correct dose and volume, and complications related to adrenaline use are rare.

Are there any risks or limitations with WALANT?

While WALANT is safe for most patients, there are some situations where caution is needed:

Patient anxiety: Some individuals may find being awake during surgery distressing, although reassurance and preparation usually help
Complex or lengthy procedures: These may still require general anaesthesia for patient comfort or technical reasons
Allergy or sensitivity to local anaesthetic: Though uncommon, alternative plans can be arranged if needed
Circulatory conditions: Patients with severe peripheral vascular disease may not be suitable candidates for adrenaline-containing solutions

How does WALANT affect recovery?

Patients often report shorter recovery times, reduced postoperative pain and quicker discharge from hospital. Because there’s no sedation, most can leave shortly after the procedure and resume normal activities sooner.

Is WALANT a safe choice for hand surgery?

Yes, for appropriate cases, WALANT is a safe and effective technique with excellent outcomes and high patient satisfaction. It represents a significant step forward in minimally invasive and patient-friendly surgical care.
