Obesity surgery

Obesity causes anesthesiologists a broad variety of perioperative theoretical and practical problems. The aim of this study was to compare two protocols of anesthesia employing Isoflurane and Sevoflurane and evaluate the cardiorespiratory parameters, postoperative recovery and analgesia. ⋯ The introduction of Sevoflurane, a volatile agent with rapid pharmacokinetic properties, seems to offer an interesting application in these patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Evaluation of core temperature during laparoscopic and open gastric bypass.
Intraoperative hypothermia is a common event during open and laparoscopic abdominal surgery. The aim of this study was to compare changes in core temperature between laparoscopic and open gastric bypass (GBP). ⋯ Perioperative hypothermia was a common event during both laparoscopic and open GBP. Despite a longer operative time, laparoscopic GBP did not increase the rate of intraoperative hypothermia when efforts were made to minimize intraoperative heat loss.

Randomized Controlled Trial Comparative Study Clinical Trial
Total intravenous anesthesia versus single breath technique and anesthesia maintenance with sevoflurane for bariatric operations.
The choice of anesthetic technique for general anesthesia in morbidly obese patients remains controversial. We aimed to compare blood gases, recovery and hemodynamic parameters using TIVA and sevoflurane anesthesia in bariatric surgery. ⋯ While sevoflurane induction and maintenance is a suitable anesthetic modality for obese patients, TIVA can be applied easily in those patients possessing no extra risk factors other than morbid obesity.

Quality of life (QoL) was tested in a 2-year postoperative study using the Medical Outcome Study Short Form 36 (MOS SF-36) to assess preoperative and 1 and 2 year postoperative QoL among one group of female patients (group 1, n = 42) and a 2 year postoperative QoL study in a second group of female patients (group 2, n = 9) who underwent a stomach reduction operation involving open surgical placement of a Lap-Band during the year 1997. ⋯ Although other authors found that QoL improves after surgical-induced weight loss, showing significant improvements on patients' perception of their health status, these findings were not confirmed in the present study. The findings show only a significant difference in bodily pain, general health and mental health perception before and after surgical intervention and preoperatively in group 1 compared to the Dutch standardized norm data. Because of small sample size (n = 9), no significant results were found in group 2 compared to the Dutch Standardized norm data. Based on earlier and present findings, further study is recommended to ascertain whether the MOS SF-36 is valid in morbidly obese patients and whether the response set has an influence on QoL studies of these patients.
