Abstract

Due to the risk of pulmonary aspiration in patients undergoing procedural sedation, the ASA continues to state that practitioners should follow preoperative fasting guidelines based on general consensus as there is insufficient studies and data to base the guidelines on. This is to ensure the safety of patients from major pulmonary complications; but it fails to take into account the post-operative complications due to prolonged fasting. The preoperative fasting guidelines recommended by the ASA are of a shorter duration than the duration recorded for many patients. In this study, data was collected from patients between 18 to 60 years of age who were undergoing elective surgery under under spinal anesthesia. The patients were selected based on the inclusion and exclusion criteria during the study period and a written informed consent was obtained from all the study participants. Antral CSA in supine D1 ranged between 3.52-5.67 and the mean value was 4.27 ± 0.45 Antral CSA in RLD D2 ranged between 3.55-5.97 and the mean value was 4.56 ± 0.50 Gastric antral area ranged between 10.69-26.83 and the mean value was 15.65 ± 3.43 Gastric volume in ml at 4th hour ranged between 16.05-63.08 and the mean value was 39.37 ±13.03 GASTRIC VOLUME 1.5Ml/kg ranged between 0.27-1.47 and the mean value was 0.65 ±0.26. Antral CSA in supine D1 ranged between 3.22-5.44 and the mean value was 4.02 ± 0.43 Antral CSA in RLD D2 ranged between 3.41-5.87 and the mean value was 4.28 ± 0.46 Gastric antral area ranged between 9.34-25.07 and the mean value was 13.68 ± 2.98 Gastric volume in ml at 6th hour ranged between 11.96-61.23 and the mean value was 35.27 ±13.38.
