Safety of oral glutamine in the abbreviation of preoperative fasting: a double-blind, controlled, randomized clinical trial.
INTRODUCTION No study so far has tested a beverage containing glutamine 2 h before anesthesia in patients undergoing surgery . OBJECTIVES The aim of the study was to investigate : 1 ) the safety of the abbreviation of preoperative fasting to 2 h with a carbohydrate-L-glutamine-rich drink ; and 2 ) the residual gastric volume ( RGV ) measured after the induction of anesthesia for laparoscopic cholecystectomies . METHODS R and omized controlled trial with 56 women ( 42 ( 17 - 65 ) years-old ) su bmi tted to elective laparoscopic cholecystectomy . Patients were r and omized to receive either conventional preoperative fasting of 8 hours ( fasted group , n = 12 ) or one of three different beverages drunk in the evening before surgery ( 400 mL ) and 2 hours before the initiation of anesthesia ( 200 mL ) . The beverages were water ( placebo group , n = 12 ) , 12.5 % ( 240 mOsm/L ) maltodextrine ( carbohydrate group , n = 12 ) or the latter in addition to 50 g ( 40 g in the evening drink and 10 g in the morning drink ) of L-glutamine ( glutamine group , n = 14 ) . A 20 F nasogastric tube was inserted immediately after the induction of general anesthesia to aspirate and measure the RGV . RESULTS Fifty patients completed the study . None of the patients had either regurgitation during the induction of anesthesia or postoperative complications . The median ( range ) of RGV was 6 ( 0 - 80 ) mL. The RGV was similar ( p = 0.29 ) between glutamine group ( 4.5 [ 0 - 15 ] mL ) , carbohydrate group ( 7.0 [ 0 - 80 ] mL ) , placebo group ( 8.5 [ 0 - 50 ] mL ) , and fasted group ( 5.0 [ 0 - 50 ] mL ) . CONCLUSION The abbreviation of preoperative fasting to 2 h with carbohydrate and L-glutamine is safe and does not increase the RGV during induction of anesthesia
