RESUMO
The management of acute burn pain poses significant challenges. Regional techniques have become increasingly popular in perioperative burn pain management. Continuous nerve block catheters are particularly useful for split-thickness skin grafts where donor site pain can exceed that of the burn-injured site. Donor skin is frequently harvested from the anterolateral thigh. The fascia iliaca (FI) compartment block provides blockade of both the lateral femoral cutaneous nerve and the femoral nerve, and thus, it is a useful modality for burn donor pain. Our institution initiated a protocol in which continuous FI catheters were placed in patients undergoing split-thickness skin grafting of the anterolateral thigh. This retrospective review seeks to assess the impact of this modality on postoperative pain scores and opioid requirements. Oral morphine equivalent (OME) administration was significantly lower in the FI group than the control group, starting with POD 0, which is the day of the FI catheter insertion (188 vs 327 mg, P < .001). Over the next 4 postoperative days (PODs), OME administration remained lower in the FI group compared to control patients, although not statistically significant on PODs 3-4. There was a significant difference in OME administered between the FI group and the control group on POD 5 (159.5 vs 209.2 mg, P < .05). Our retrospective study evaluating the role of FI catheters in burn patients undergoing split-thickness skin grafting surgery showed significantly lower opioid consumption on PODs 1-5 compared to patients without an FI catheter.
