Abstract
A 29-year-old patient with normal preanesthetic evaluation was planned for percutaneous nephrolithotomy (PCNL) for right nephrolithiasis with right pyelolithiasis. Surgery was performed under general anesthesia with endotracheal intubation with muscle relaxation. At the conclusion of surgery, when the patient was turned over to supine position, tense abdomen was noted. Immediately extended focused assessment with sonography in trauma (eFAST) was done in which both right and left quadrants of abdomen including pericardial and suprapubic region, right and left thoracic, and both lung basis were examined. Fluid collection was seen in Morison's pouch which was drained by the urologist under real-time ultrasonography guidance by anesthesiologist. Distension of abdomen subsequently subsided and patient had normal vitals. Trachea was extubated and patient shifted to post-operative ward. eFAST and FAST scans are routine procedures in the rapid assessment of trauma victims in emergency settings. The fluid extravasation during a routine PCNL procedure may lead to abdominal compartment syndrome. This case demonstrated that use of eFAST rapidly detected abdominal collection and ruled out life-threatening conditions such as hemothorax and pneumothorax and prevented abdominal compartment syndrome. Our case is only an example that potentially lethal conditions like these may be encountered in the perioperative setting and the knowledge of eFAST scan may be of great help.
