Effect of intraoperative amino acids with or without glucose infusion on body temperature, insulin, and blood glucose levels in patients undergoing laparoscopic colectomy: a preliminary report.

Abstract

OBJECTIVE:

Amino acid administration helps to prevent intraoperative hypothermia but may enhance thermogenesis when combined with glucose infusion. The aim of this study was to examine the effect of intraoperative amino acid administration, with or without glucose infusion, on temperature regulation during laparoscopic colectomy.

METHODS:

Twenty-one patients whose physical status was classified I or II by the American Society of Anesthesiologists, and who were undergoing elective laparoscopic colectomy were enrolled. The exclusion criteria were a history of diabetes and/or obesity, preoperative high levels of C-reactive protein, high blood glucose and/or body temperature after anesthesia induction, and surgical time >500 minutes. Each patient received an acetate ringer solution and was randomly assigned to one of three groups. Group A patients were given only amino acids. Group AG patients were given amino acids and glucose. Group C patients were given neither amino acids nor glucose. Tympanic membrane temperatures and blood glucose and insulin levels were measured intraoperatively.

RESULTS:

Intraoperative amino acid infusion significantly increased body temperature during surgery as compared with either Group AG or C. The blood glucose levels in Group AG were significantly higher than those in Groups A and C. However, there were no significant differences between Groups A and C. Two hours after anesthesia induction, serum insulin levels in Groups A and AG significantly increased compared with Group C. No significant differences in the postoperative complications or patient hospitalization lengths were detected between the groups.

CONCLUSION:

Intraoperative amino acid infusion without glucose administration maintains body temperature more effectively than combined amino acid and glucose infusion in patients undergoing laparoscopic colectomy, despite unaltered intraoperative insulin levels.
