Randomized Controlled Trial
Randomized, double-blind, placebo-controlled trial using lidocaine patch 5% in traumatic rib fractures.
The lidocaine patch 5% was developed to treat postherpetic neuralgia. Anecdotal experience at our institution suggests the lidocaine patch 5% decreases narcotic usage in patients with traumatic rib fractures. This trial was developed to define the patch's efficacy. ⋯ The lidocaine patch 5% does not significantly improve pain control in polytrauma patients with traumatic rib fractures.

Randomized Controlled Trial Comparative Study
Randomized trial of emergency endoscopic sclerotherapy versus emergency portacaval shunt for acutely bleeding esophageal varices in cirrhosis.
The mortality rate of bleeding esophageal varices in cirrhosis is highest during the period of acute bleeding. This is a report of a randomized trial that compared endoscopic sclerotherapy (EST) with emergency portacaval shunt (EPCS) in cirrhotic patients with acute variceal hemorrhage. ⋯ EPCS permanently stopped variceal bleeding, rarely became occluded, was accomplished with a low incidence of portal-systemic encephalopathy, and compared with EST, produced greater longterm survival. The widespread practice of using surgical procedures mainly as salvage for failure of endoscopic therapy is not supported by the results of this trial (clinicaltrials.gov #NCT00690027).

Randomized Controlled Trial
Closed loop control of inspired oxygen concentration in trauma patients.
Transport of mechanically ventilated patients in a combat zone presents challenges, including conservation of resources. In the battlefield setting, provision of oxygen supplies remains an important issue. Autonomous control of oxygen concentration can allow a reduction in oxygen usage and reduced mission weight. ⋯ Closed loop control of FIO(2) offers the opportunity for maximizing oxygen resources, reducing mission weight, and providing targeted normoxemia without increasing risk of hypoxemia in ventilated trauma patients.

Randomized Controlled Trial
Less is more: improved outcomes in surgical patients with conservative fluid administration and central venous catheter monitoring.
The ARDS Clinical Trials Network Fluid and Catheter Treatment Trial (FACTT) addressed fluid management and central monitoring of patients with acute respiratory distress syndrome/acute lung injury (ARDS/ALI). Because surgical patients may have been fundamentally different from the overall FACTT cohort, we set out to separately analyze the surgery patients in the trial. ⋯ The risk of death did not vary with fluid management or catheter. A conservative fluid-administration strategy and central venous catheter monitoring resulted in more ventilator-free and ICU-free days in surgical patients with acute lung injury, and conservative fluid administration did not result in more renal failure.

Randomized Controlled Trial Multicenter Study
Does type of pancreaticojejunostomy after pancreaticoduodenectomy decrease rate of pancreatic fistula? A randomized, prospective, dual-institution trial.
Pancreatic fistula (PF) is one of the most common complications after pancreaticoduodenectomy. There have been no large prospective randomized trials evaluating PF rates comparing invagination versus duct to mucosa pancreaticojejunostomy. We tested the hypothesis that a duct to mucosa pancreaticojejunostomy would reduce the PF rate. ⋯ This dual-institution prospective randomized trial reveals considerably fewer fistulas with invagination compared with duct to mucosa pancreaticojejunostomy after pancreaticoduodenectomy. Results confirm increased PF rates in soft as compared with hard glands. Additional studies are needed to define the optimal technique of pancreatic reconstruction after pancreaticoduodenectomy.
