Background: Evidence for post-operative care of lower extremity free flap reconstruction (LEFF) varies and is yet to be standardized, despite established guidelines by the Orthopedic Association Standard for Trauma (BOAST-4). This study assesses post-operative protocols for LEFF clinical monitoring, warming, dangling, and compression in UK Major Trauma Centers (MTCs).
Methods: An online questionnaire was distributed to consultant leads of all UK adult MTCs. Data requested the existence of a standardized protocol, intensity and takeback of LEFF procedures and specific practices in clinical monitoring, warming, dangling, and compression. Analysis was performed in Excel.
Results: The survey was returned by 23 (79.3%) units and most (86.9%) had standardized LEFF monitoring protocols. Centers typically performed 4-8 surgeries monthly and on average had 2.7 salvageable LEFFs in 2022. Clinical monitoring was common (>92%) and included color, capillary refill and temperature assessment. Compression initiation varied with 45.5% starting after day 7 and 40.9%, between days 3-5. Continuous compression was favored (78.3%), using pillows (88.9%). Dangling protocols begin between days 3-7, for 5 minutes (52.2%) with frequencies of three to four times daily (25%-37.5%). The preferred tool for LEFF warming was the Bairhugger (82.6%) and the mean termination day for warming was 3.61.
Conclusion: The survey highlights the need for evidence-based and consensus in UK MTC protocols for LEFFs. We encourage ongoing research and collaborative efforts in creating an accepted protocol among MTCs that could be incorporated into the BOAST-4 guidelines for postoperative care standardization and improved patient outcomes.
