| Abstract Background: As patients turned into prone position expe-rienced change in heamodynamics (heart rate and mean arterial blood pressure) than those on supine position, this prospective, randomized study was designed to compare the effect of PCV and Volume-Controlled Ventilation (VCV) on heamodynamics in the prone position using the Wilson frame during elective lumbar spine surgery. Patients and Methods: Sixty patients scheduled for elective lumbar spine surgery were randomly allocated to receive mechanical ventilation using either the VCV (n=30) or PCV (n=30) mode. Hemodynamic variables (heart rate, mean arterial blood pressure). Results: Heart rate as beat/min. (p-value 1): In volume controlled group during supine position mean ± SD value was (76±12) and during prone position was (69±12) and in pressure controlled group it was (82±17) in supine position and (72±13) in prone position and mean arterial blood pressure as mmHg (p-value 0.6): In volume controlled group mean ± SD in supine position was (80±9) and in prone position it was (77±11), and in pressure controlled group it was (84±14) in supine position and (77±9) in prone position. Conclusions: PCV provides lower Ppeak compared with VCV when the ventilator is set to deliver the same tidal volume and variable respiratory rate to maintain a constant end-tidal carbon dioxide tension in patients undergoing pos-terior lumbar spine surgery in the prone position using the Wilson frame. | ||||
