Comparative Study
Colectomy performance improvement within NSQIP 2005-2008.
All open and laparoscopic colectomies submitted to the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) were evaluated for trends and improvements in operative outcomes. ⋯ It appears that laparoscopic colectomies are growing in popularity over open colectomies, but the need for emergent open procedures remains unchanged. Across all colectomies, however, key postoperative and perioperative complications have improved over time. Participation in ACS NSQIP demonstrates quality improvement and may encourage greater enrollment.

Near-infrared spectroscopy (NIRS) has been shown to provide reliable noninvasive monitoring of regional oxygenation in a variety of clinical settings. We set out to test its feasibility as a monitor of fetal and placental oxygenation during fetal cardiac surgery. ⋯ This is the first report of application of NIRS in the setting of fetal surgery. NIRS permits noninvasive assessment of placental oxygen saturation and pO(2). This technology is a simple and useful tool for real-time monitoring of oxygen delivery to the fetus during maternal-fetal cardiac interventions and of overall well-being of the fetal-placental unit.

Lower limb ischemia-reperfusion (I/R) elicits oxidative stress and causes inflammation in lung tissues that may lead to lung injury. Magnesium sulfate (MgSO(4)) possesses potent anti-oxidation and anti-inflammation capacity. We sought to elucidate whether MgSO(4) could mitigate I/R-induced lung injury. As MgSO(4) is an L-type calcium channel inhibitor, the role of the L-type calcium channels was elucidated. ⋯ MgSO(4) mitigates lung injury induced by bilateral lower limb I/R in rats. The mechanisms may involve inhibiting the L-type calcium channels.

In this study, we investigated the efficacy of a fibrinogen/thrombin-coated collagen patch (TachoSil) to terminate severe bleeding in a coagulopathic pig model with blunt liver injury. ⋯ TachoSil under severe coagulopathy effectively controlled bleeding and successfully prevented hemorrhagic death.

Randomized Controlled Trial
The effect of intraperitoneal ropivacaine on pain after laparoscopic colectomy: a prospective randomized controlled trial.
Although laparoscopic procedures are becoming more common, postoperative pain remains a major factor causing delayed patient recovery. There have been several trials to reduce pain by instilling local anesthetics into the peritoneal cavity, but there has been no study on prolonged (∼300 min) or intensive surgery. We investigated the analgesic effect of intraperitoneal ropivacaine instillation after laparoscopic colectomy. ⋯ The intraperitoneal instillation of ropivacaine was effective in reducing postoperative pain and in shortening the recovery course after laparoscopic colectomy. The additional instillation of ropivacaine at the end of the surgery proved even more effective.
