Groin flap immobilization by axillary brachial plexus block anesthesia.

Pedicled groin flaps are still widely used as soft tissue coverage in hand surgery. Various methods have been described for immobilization of flaps, such as Ace wraps, plaster, and external fixators. The hands of 5 females and 12 males, totaling 17 patients, with severe injury were reconstructed with groin flaps between 2001 and 2005. Patients were operated on under a combination of axillary block and general anesthesia. Motor block effect of axillary anesthesia was used for immobilization of the upper extremities at groin flap coverage. A combination of axillary brachial plexus block plus general anesthesia had advantages in the prevention of pedicle tension or torsion during the initial recovery period. Reduction of general anesthesia time and improvement of postoperative pain were also observed. Axillary brachial plexus block and general anesthesia are a preferred combination for patients undergoing groin flap operations.
