ABSTRACT
Objective To explore the effect of three surgical positions on needle-assisted thoracoscopic sympathicotomy. Methods Sixty patients undergoing needle-assisted thoracoscopic sympathicotomy were divided into lateral position group，Fowler position group，and modified Fowler position group. The position of the endotracheal tube，noninvasive blood pressure (NIBP) and heart rate were monitored before and after the body position was changed. Moreover，the exposure of surgical field,operation time and comfort degree of patients were recorded. Results The operations were completed successfully under the three positions. Modified Fowler position provided better surgical field and higher comfort degree of patients. Moreover,it was convenient for operative procedure and shortened the operation duration. Conclusion During the operation of needle-assisted thoracoscopic sympathicotomy,modified Fowler position can provide better surgical exposure,enhance comfort of patients,stabilize hemodynamics and shorten operation duration.
