Comparison between Volume controlled ventilation and Pressure controlled volume guaranteed ventilation in postoperative lung atelectasis using lung ultrasound following Upper Abdominal Laparotomies

Abstract

telectasis is a common side effect of general anesthesia. Prevention of lung atelectasis, carbon dioxide retention and chest infection would improve the quality of medical care, and decrease hospital stay and costs. Lung ultrasonography in the perioperative period is feasible, allows tracking of perioperative atelectasis, with Sensitivity and specificity to detect atelectasis is 93% and 100%, respectively. Recently, a specific ultra-sonographic detection of the cardiac impulse definition termed the lung pulse has been reported to be a highly sensitive early indicator of the presence of atelectasis. Volume-controlled ventilation mode (VCV) is commonly used during general anesthesia while pressure controlled ventilation with volume guaranteed mode (PCVG) has recently been introduced in the field of anesthesiology.
