The Effect of the Prone Position on Venous Pressure and Blood Loss During Lumbar Laminectomy.
Journal of clinical anesthesia(1992)
摘要
Study Objective: To determine the effects of three different prone support systems (Andrews spinal surgery frame, Cloward surgical saddle, and longitudinal bolsters) on inferior vena cava (IVC) and superior vena cava (SVC) pressures; the validity of measuring central venous pressure (CVP) for the determination of ideal positioning of the patient; and the relationship among frame type, blood loss, and hemodynamic measurements.
