288EFFECT OF GASTRIC DECOMPRESSION ON POSTOPERATIVE NAUSEA AND VOMITING IN EAR, NOSE, AND THROAT SURGERY: A COMPREHENSIVE ANALYSISDuring oral and nasal surgery, blood flows passively to the stomach. There is a possibility that it will cause postoperative nausea and vomiting (PONV). A relationship was found between the severity of PONV after ear, nose and throat (ENT) surgery and gastric decompression (GD). The study included 274 patients who underwent ENT surgery. GD was given to patients in Group I (140) before extubation; GD was not given to patients in Group II (134). There were significantly more PONV cases in Group II in the 2nd, 4th, 8th, and 12th hours after surgery than in Group I. PONV was also significantly worse in Group II than in Group I. When stomach content aspirated more than 10 mL in Group I, the PONV ratio in the 2nd hour was significantly higher than that of stomach content aspirated less than 10 mL in Group I. The stomach content aspired and PONV ratio did not differ statistically significantly in the 4th, 8th, or 24th hours. PONV is less likely to occur and be moderate in ENT surgeries when GD is used.Ramgopal@gmail.comResearch1222022 Surgery, Gastric, Nausea, Vomiting, Ear, Nose, ThroatDr Singh Ravi RamgopalAssistant Professor, Department of ENT, Gouri Devi Medical College, Durgapur, West Bengal, India
