BACKGROUND: To reduce the risk of regurgitation during anesthesia for elective procedures, residual gastric volumes (RGV) have traditionally been minimized with overnight fasting. Prolonged preoperative fasting have some adverse consequences and has been abandoned for most surgical procedures, with the exception of obese and/or diabetic patients.
AIMS: The aim of this study was to assess the RGV in morbidly obese diabetics patients after traditional or abbreviated fasting.
METHODS: This study was approved by the Committee of Ethics in Research in Human Beings from the Federal University of Mato Grosso, number 179.017/2012. This is a prospective, randomized, and cross-over design in 8 morbidly obese type II diabetic patients. RGV was measured endoscopically after either traditional overnight fasting (at least 8 hours) or after abbreviated fasting (6 h for solids and 3 hours for a drink containing water plus 25 g (12.5%) of maltodextrin). Data are expressed as mean and range and differences were compared with paired t tests at p<0.05.
RESULTS: The study population was 41.5 (28-53) years old, with a mean weight of 135 (113-196) kg, body mass index (BMI) 48.2 (40-62.4) kg/m2, and having type II diabetes for 4.5 (1-10) years. The RGV after abbreviated fasting was 21.5 (5-40) ml vs 26.3 (7-65) ml after traditional fasting. This difference was not significant (p=0.82).
CONCLUSIONS: Gastric emptying in morbidly obese diabetics patients is similar after either traditional or abbreviated fasting with a carbohydrate drink.
