Randomized Controlled Trial Comparative StudyEffects of epidural-and-general anesthesia combined versus general anesthesia alone on femoral venous flow during laparoscopic cholecystectomy.
The pneumoperitoneum has been shown to decrease femoral blood flow, resulting in venous stasis. We analyzed the effects of the pneumoperitoneum and epidural analgesia on femoral vein diameter and the peak flow rate of femoral vein during laparoscopic cholecystectomy. ⋯ Abdominal insufflation during laparoscopic cholecystectomy results in dilation and decreased flow in the common femoral vein. Epidural analgesia added to the GA partially compensated for the reduction in femoral PFR.
