ClinConnect Summary

The number of spine surgeries has increased in recent years due to degenerative diseases of the spine and age. Lumbar spine surgery is a surgery performed in the prone position. Changing the patient's position from supine to prone may cause a decrease in cardiac output, arterial pressure and tissue perfusion due to the decrease in the preload of the heart. In addition to the decrease in venous return due to increased intra-abdominal pressure, left ventricular compliance may be impaired due to increased thoracic pressure. All these changes may cause decreased cardiac output and systemic hypo...
