Abstract：Objective To investigate the effect of personalized preoperative fasting plans on elderly hip replacement patients.Methods Using the random number table method, patients who underwent hip replacement surgery between June 2016 and December 2017 were divided into the experimental group and control group. In the control group, 53 patients received traditional preoperative fasting plans while 57 patients in the experimental group received personalized fasting schemes. By evaluating the conditions of patients and estimating the time of operation, the patients were given individualized drinking before surgery. The actual duration of fasting and water-deprivation, moderate to severe thirst, moderate to severe hunger, postoperative stress hyperglycemia, the incidence of nausea and vomiting during postoperative 24 h, and hospital stay were compared between the two groups.Results The actual duration of water-deprivation[(2.39±0.58) h] was shorter in the experimental group than [(13.96±11.39)h]in the control group, so was the duration of actual fasting time[(7.76±0.92)h vs (16.08±1.60). h], and the difference was statistically significant. The incidence of severe thirst (1.75%) and hunger (5.26%) in the experimental group was lower than that in the control group (18.87%, 33.96%), so the difference was statistically significant. The rate of post-stress hyperglycemia (0%) was lower than that of the control group (9.43%), so was the incidence of nausea and vomiting at 24 h [(1.75%) vs (13.2%)]. The difference was statistically significant. Hospital stay in the experimental group (5.64±0.49) d was significantly shorter than that of the control group (7.80±1.04) d, and the difference was statistically significant.Conclusions The implementation of the personalized preoperative fasting program can effectively shorten the time of fasting before surgery, reduce preoperative hunger, thirst, and the incidence of preoperative hypoglycemia and postoperative nausea and vomiting. The incidence of postoperative aspiration can be reduced, patients’ mood boosted and hospital stay shortened.
