Preoperative oral carbohydrate intake in patients undergoing LC day surgery

Objective To evaluate preoperative oral carbohydrate in patients receiving LC day surgery. Methods 117 patients undergoing LC day surgery in PLA General Hospital from Oct 2016 to Mar 2017 were evenly divided into three groups. Patients in group A took oral carbohydrate preoperatively, group B by iv glucose, group C by overnight fasting. The preoperative thristy and the indicators of inflammation, heart rate, blood glucose, serum insulin, insulin resistance index postoperatively were collected and compared. Results No patients suffered aspiration. There were no complications above Clavien Ⅰ level. Differences in insulin resistance index, fasting serum insulin were statistically significant between group A and group B (Z=-5.60, -4.78, P<0.05). That of insulin resistance index, fasting serum insulin and procalcitonin between group A and group C were statistically significant (Z=-2.65, -2.49, -4.02, P<0.05). Procalcitonin between group B and group C were statistically different (Z=-2.183, P<0.05). The preoperative thristy between group A and group B, group C were statistically different (χ2=6.47, P<0.05). Conclusions Preoperative oral carbohydrate intake is safe and feasible with the benefits of improving the quality of life in patients operated on LC day surgery.
