The present systematic review shows that , with the exception of laparoscopic surgery , objective evidence of the effect of individual components of ERAS protocol s in reducing the stress response following colorectal surgery is limited
Abstract Enhanced Recovery or Fast Track Recovery after Surgery protocol s ( ERAS ) have significantly changed perioperative care following colorectal surgery and are promoted as reducing the stress response to surgery .
Perioperative gastric emptying is not a predictor of early postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.
UNLABELLED It is not known whether patients with postoperative nausea and vomiting ( PONV ) have delayed gastric emptying compared with patients without PONV . We compared the perioperative rate of gastric emptying in patients experiencing PONV with the rate in those without PONV immediately after laparoscopic cholecystectomy .  Gastric emptying was studied by the acetaminophen method . Acetaminophen is not absorbed from the stomach but is rapidly absorbed from the small intestine , and the rate of gastric emptying therefore determines the rate of absorption of acetaminophen administered into the stomach . Forty patients ( ASA physical status I and II ) were included in the study . After the induction of anesthesia , a gastric tube was positioned in the stomach and 1.5 g of acetaminophen dissolved in 200 mL of water was administered . Venous blood sample s for the determination of serum acetaminophen concentrations were taken before and at 15-min intervals during a period of 180 min after the administration of acetaminophen .  Twenty-six patients experienced nausea during the first 4 h postoperatively . The other 14 patients had no nausea . There were no statistically significant differences in the maximal acetaminophen concentration , the time taken to reach the maximal concentration , or the area under the serum acetaminophen concentration time curves from 0 to 60 , 0 - 120 , and 0 - 180 min between the groups of patients with or without PONV . We did not find any relationship between postoperative gastric emptying and PONV , and therefore gastric emptying is not a predictor of PONV . IMPLICATION S The incidence of postoperative nausea and vomiting is frequent after laparoscopic cholecystectomy . This study has shown that perioperative gastric emptying is not a predictor of early postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy
