Venous air embolism in sitting and supine patients undergoing vestibular schwannoma resection.

摘要: OBJECTIVE: This study retrospectively compares the incidence of venous air embolism (VAE) detection and morbidity in sitting supine positions. All patients underwent vestibular schwannoma resection via retrosigmoid approach by a single surgical team. METHODS: A total 432 consecutive operations were reviewed, 222 which performed with position 210 position. Charts reviewed for evidence intraoperative VAE, hypotension secondary to postoperative related other variables compare groups. RESULTS: demonstrated 28% VAE when compared 5% (P < 0.0001). Intraoperative was noted 1.8% 1.4% = 0.72, no significant difference). Postoperative caused one patient (0.5%) (pulmonary edema) 0.48, Blood loss slightly greater group, operative times similar both groups, despite that average tumor size operated on 2.8 cm versus 2.2 group CONCLUSION: Our results indicate although there is higher patients, not statistically greater. We conclude because from either position, positioning should be based team preference.
