A randomized controlled trial of sitting position and supine position in bronchoscopy on securing a clear airway during anesthesia / 中国内镜杂志

ABSTRACT

Objective To study the airway patency during sitting position and supine position in bronchoscopy during anesthesia. Method Forty-eight patients underwent bronchoscopy during Non-intubation anesthesia were randomly allocated to two groups.There were 24 cases in each group by observeing the airway patency and vital signs of the two groups during the procedure. Result Sitting position in bronchoscopy during anesthesia have the shorter average time to reach the carina, on securing a clear airway. The incidence of desaturation, hypertension and agitation were lower in sitting position during bronchoscopy. Conclusion Bronchoscopy anesthesia can reduce discomfort and fear, but traditional supine bronchoscopy anesthesia can cause displacement of the tongue, collapse of the upper airway in the oropharynx, soft palate and vocal cord related to gravity may seriously obstruct the upper airway, not only brings inconvenience to the inspection, but also increases the risk of airway correlation and hemodynamic instability, Sitting bronchoscopy ensure the airway patency and maintain a more stable hemodynamic state, so that sitting position in the sedation of bronchoscopy anesthesia is safer and more convenient.
