Randomized Controlled Trial Comparative Study Clinical Trial
Complete versus selective portal triad clamping for minor liver resections: a prospective randomized trial.
To evaluate the feasibility, safety, efficacy, amount of hemorrhage, postoperative complications, and ischemic injury of selective clamping in patients undergoing minor liver resections. ⋯ Both techniques of clamping are equally effective and feasible for patients with normal liver and undergoing minor hepatectomies. However, in cirrhotic patients selective clamping induces less ischemic injury and should be recommended. Finally, even for minor hepatic resections, central venous pressure, HVPG, and intraoperative blood loss are factors related to morbidity and should be considered.

Randomized Controlled Trial Comparative Study Clinical Trial
Glutamine supplementation of parenteral nutrition does not improve intestinal permeability, nitrogen balance, or outcome in newborns and infants undergoing digestive-tract surgery: results from a double-blind, randomized, controlled trial.
To assess the effect of isocaloric isonitrogenous parenteral glutamine supplementation on intestinal permeability and nitrogen loss in newborns and infants after major digestive-tract surgery. ⋯ In newborns and infants after major digestive-tract surgery, we did not identify beneficial effects of isonitrogenous, isocaloric glutamine supplementation of parenteral nutrition. Glutamine supplementation in these patients therefore is not warranted until further research proves otherwise.
