Özet
Study Objective: To investigate the effects of tympanometric changes on the frequency of postoperative nausea and vomiting (PONV). Design: Prospective, observational study. Setting: University hospital. Patients: 49 ASA physical status 1, nonpremedicated children undergoing elective strabismus surgery. Interventions: Frequency of PONV was assessed at various time intervals (0-2, 2-6, and 6-24 hours) with a 4-point scale (0, no nausea; 1, nausea but no vomiting; 2, one episode of vomiting; 3, two or more episodes of vomiting), and correlation with tympanometric data was investigated. Measurements: Tympanogram was obtained before induction of standardized anesthesia and after full recovery. Fourteen (28.6%) patients had nausea, and 10 (20.4%) patients vomited. The tympanic gradient, compliance, and pressure values were found to be significantly higher in postoperative measurements than their preoperative counterparts (P < 0.05). The volumes of both ears increased postoperatively, but these differences were not statistically significant (P > 0.05). Changes in middle car pressure, volume, compliance, and gradient did not correlate with PONV (P > 0.05). Conclusions: Gradient, compliance, volume, and pressure changes in middle ears were not found to be related to the frequency of nausea and vomiting after strabismus surgery. (c) 2007 Elsevier Inc.
