Comparative Study
Comparison of two gelatin and thrombin combination hemostats in a porcine liver abrasion model.
Surgical hemostasis is achieved using adjunctive hemostats when conventional methods fail. ⋯ Smooth gelatin has an increased ability to retain thrombin and RBC's in vitro which may explain why it provides superior hemostatic effectiveness, superior control of bleeding, and greater reduced blood loss in vivo.

The involvement of voltage-dependent calcium channels and reactive oxygen species in the pathophysiology of neuropathic pain might justify the preventative administration of antioxidant enzymes, at low doses, in combination with gabapentin (GaP) to maximize its analgesic effect in an experimental model of neuropathic pain in rats. ⋯ These results suggest that preventive antioxidants in combination with GaP provided a synergistic suppression of thermal hypersensitivity that GaP alone cannot produce.

Randomized Controlled Trial
Oral carbohydrate supplementation reduces preoperative discomfort in laparoscopic cholecystectomy.
The aim of this study was to investigate the effects of oral carbohydrate solution (CHO) on perioperative discomfort, biochemistry, hemodynamics, and patient satisfaction in elective surgery patients under general anesthesia. Sixty cases in ASA I-II group who were planned to have operation under general anesthesia were included in the study. The cases were randomly divided into two groups having 30 subjects in each. ⋯ Gastric volumes were higher in the control group; gastric pH values were found significantly higher in the study group. The level of anxiety and depression risk rate were found lower in the study group. In conclusion, preoperative CHO reduces perioperative discomfort and improves perioperative well being when compared to overnight fasting.

Comparative Study
Caffeic acid phenethyl ester prevents detrimental effects of remote ischemia-reperfusion injury on healing of colonic anastomoses.
We aimed to investigate whether caffeic acid phenethyl ester (CAPE) prevents detrimental systemic effects of intestinal ischemia-reperfusion (IR) injury on colonic anastomotic wound healing. ⋯ This study clearly showed that CAPE treatment prevented the delaying effects of remote IR injury on colonic anastomotic wound healing. Further clinical studies are required to determine whether CAPE has a useful role in the enhancement of gastrointestinal anastomotic wound healing during particular surgeries in which IR-induced organ injury occurs.

To improve methods for the treatment of intractable pain, we are developing a novel intradural spinal cord stimulator that could be either attached to the dentate ligaments of the human spinal cord or fitted around the dorsal arc of the cord itself. ⋯ We demonstrated that the dural attachment method is an effective surrogate model for testing the human dentate ligament device fixation technique, and that this mode of fixation was preferable to dorsal arc attachment. The relevant surgical innovations, anatomical findings, and the preliminary electrophysiological data from a pial surface stimulator attached in this way are presented.
