Effects of preoperative fasting abbreviation with carbohydrate and protein solution on postoperative symptoms of gynecological surgeries: double-blind randomized controlled clinical trial.

OBJECTIVE

to investigate the effects of preoperative fasting abbreviation, a recommendation of Postoperative Accelerated Total Recovery protocol (ACERTO protocol), on postoperative symptoms of patients undergoing gynecological surgeries.

METHODS

a double-blind randomized controlled study of 80 gynecological surgeries performed from January to June 2016. The patients were randomly allocated into two groups: Controle Group, with 42 patients, and Juice Group, with 38 patients, who received 200ml inert solution or 200ml carbohydrate- and protein-enriched liquid, respectively, four hours before surgery. The postoperative symptoms studied were thirst, hunger, pain, agitation, satisfaction, and well-being in both groups. To measure the intensity of symptoms, we used the Visual Analog Scale (VAS), associated with the Facial Scale (FS) for pain, applied ten hours after surgery.

RESULTS

patients in the Juice Group had less pain (3.51x1.59), thirst (3.63x0.85), hunger (3.86x2.09), and agitation (2.54x0,82) in relation to the Controle Group (P<0.05). Satisfaction (6.89x8.68) and well-being (5.51x7.12) variables were higher (P<0.05) when the carbohydrate- and protein-containing liquid (Juice Group) was ingested in relation to the inert solution (Controle Group).

CONCLUSION

the abbreviation of preoperative fasting with carbohydrate- and protein-containing liquid before gynecological surgeries reduces thirst, hunger, pain, agitation, and favors greater satisfaction and well-being than inert solution ingestion.
