Randomized Controlled Trial Clinical Trial
Beneficial effects of humidified, warmed carbon dioxide insufflation during laparoscopic bariatric surgery: a randomized clinical trial.
Recent data has shown that the use of warmed, humidified carbon dioxide (CO2) insufflation during laparoscopic surgery may be associated with better outcomes. ⋯ The use of warmed, humidified CO2 insufflation in bariatric patients undergoing LRYGBP was not associated with any significant benefit with regards to postoperative pain.

Certain adipose-produced signals are secreted in proportion to body fat mass and are involved in regulation of the energy metabolism of the whole body. Leptin, IL6 and adiponectin can be considered as adiposity signals. Several Single Nucleotide Polymorphisms (SNPs) in genes encoding for these molecules are known to influence their concentration in situations of stable weight. We hypothesized that polymorphism effects could be better detected in a situation of negative energy balance and that modified concentrations of adiposity signal genes could change the dynamics of weight gain in obese subjects. ⋯ We observed that the SNPs studied could modulate the concentration of adiposity signals not only at baseline but also during weight loss. Such variations may be sensed by the homeostatic feedback system that controls energy balance and may in turn contribute to some disturbances in weight regulation.

Bispectral Index (BIS) monitoring in morbidly obese patients undergoing gastric bypass surgery: experience in 23 patients.
Early and uneventful postoperative recovery of morbidly obese patients remains a challenge for anesthesiologists. BIS monitoring is useful in providing fast recovery. ⋯ Propofol-nitrous oxide anesthesia adjusted to keep BIS around 60, combined with thoracic epidural analgesia, seems to be effective in providing predictable and uneventful recovery to patients submitted to elective RYGBP.
