Continuous Transversus Abdominis Plane (TAP) Block Catheters in a Combat Surgical Environment

Abstract

The ongoing conflict in Afghanistan continues to generate a large number of complex trauma injuries and provides unique challenges to military anesthetists working in forward field hospitals. We report successful use of ultrasound-guided continuous transversus abdominis plane (TAP) block in two Afghan war casualties who sustained major trauma with coagulopathy. The use of bilateral continuous TAP blocks following major thoracoabdominal trauma in a combat environment is unique in the literature. Case report. The acute perioperative outcomes of two Afghan civilian patients were improved with bilateral continuous TAP blocks. Multiple benefits shared by both patients included early extubation, excellent analgesia, and minimal post-operative morphine requirements despite the setting of a massive blood transfusion and coagulopathy. A continuous TAP block technique can be utilized to provide excellent analgesia following major abdominal surgery when neuraxial anesthesia is contraindicated. The TAP block's ease of placement under ultrasound guidance makes this technique particularly useful in the austere battlefield hospital environment.
