Haemostatic effects of adrenaline-lidocaine subcutaneous infiltration at donor sites.

Abstract

This study sought methods in burn surgery to reduce postoperative pain and blood loss at donor sites. A prospective, randomised, controlled, blinded trial included 56 people undergoing burn surgery, divided into two groups. Both groups received subcutaneous infiltration at donor sites, with either 1:500,000 adrenaline solution containing added lidocaine or with 0.45% normal saline (controls). Outcome measurements included amount of intraoperative bleeding, need for electrocautery, days the hydrocolloid dressing remained on donor sites, percentage of re-epithelialised skin at donor sites 1 week after surgery and viability of skin grafts. Results indicated that subcutaneous adrenaline-lidocaine infiltration at donor sites reduced intraoperative bleeding, decreased postoperative pain, shortened the duration of surgery and general anaesthesia and accelerated re-epithelialisation at the donor site. The overall graft take in both groups was similar.
