Abstract

The aim of the study was to evaluate the effects of preoperative fasting and fluid limitation in patients undergoing laparoscopic cholecystectomy. Although traditional long-term fasting is not recommended in current preoperative guidelines, this is still a common intervention. Visual analogue scale was used to assess hunger, thirst, sleepiness, exhaustion, nausea and pain; State and Trait Anxiety Inventory was used to assess the preoperative anxiety of 99 patients undergoing elective laparoscopic cholecystectomy. Mean time of preoperative fasting and fluid limitation were, respectively, 14.70 ± 3.14 and 11.25 ± 3.74 h. Preoperatively, 58.60% of the patients experienced moderate anxiety. Patients fasting 12 h or longer had higher hunger, thirst, nausea and pain scores. The mean trait anxiety score of patients fasting 12 h or longer was statistically significantly higher. Receiving nothing by mouth after midnight preoperatively is a persisted intervention and results in discomfort of patients. Clinical protocols should be revised and nurses should be trained in current fasting protocols.
