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 .
A Carbohydrate-Rich Drink Reduces Preoperative Discomfort in Elective Surgery Patients
We studied the effects of different preoperative oral fluid protocol s on preoperative discomfort , residual gastric fluid volumes , and gastric acidity .  Two-hundred-fifty-two elective abdominal surgery patients ( ASA physical status I – II ) were r and omized to preparation with a 12.5 % carbohydrate drink ( CHO ) , placebo ( flavored water ) , or overnight fasting . The CHO and Placebo groups were double-blinded and were given 800 mL to drink on the evening before and 400 mL on the morning of surgery . Visual analog scales were used to score 11 different discomfort variables . CHO did not increase gastric fluid volumes or affect acidity , and there were no adverse events . The visual analog scale scores in a control situation were not different between groups . During the waiting period before surgery , the CHO-treated group was less hungry and less anxious than both the other groups ( P ≤ 0.05 ) . CHO reduced thirst as effectively as placebo ( P < 0.0001 versus Fasted ) . Trend analysis showed consistently decreasing thirst , hunger , anxiety , malaise , and unfitness in the CHO group ( P < 0.05 ) . The Placebo group experienced decreasing unfitness and malaise , whereas nausea , tiredness , and inability to concentrate increased ( P < 0.05 ) . In the Fasted group , hunger , thirst , tiredness , weakness , and inability to concentrate increased ( P < 0.05 ) . In conclusion , CHO significantly reduces preoperative discomfort without adversely affecting gastric contents
