Abstract
Background
Thoracoscopic surgeries are an absolute indication of one lung ventilation OLV, the choice of using volume-controlled ventilation (VCV) or pressure controlled ventilation (PCV) remains controversial. Respiratory complications are major cause of postoperative morbidity which is associated with increased extravascular lung water (EVLW). Assessment of (EVLW) helps in early detection and treatment of respiratory complications. Lung ultrasound (LUS) has been suggested as reliable method of assessment of EVLW. This study was designed to figure out whether there was any difference in OLV by either PCV or VCV on EVLW water in the ventilated lung using LUS score and arterial oxygenation.
Methodology
50 patients were randomly assigned into two groups; Group V: received VCV (Vt 7 ml/kg ideal body weight) Group P: received PCV (To achieve Vt 7 ml/kg ideal body weight, Pmax 30 cmho)
Results
We found that both techniques PCV and VCV showed no statistically significant differences as regards the ultrasound score at different timings of measurement; (T0) before induction of anesthesia, (T5) immediately at the end of operation after extubation, and (T6) 2 hours after ICU admission. Where P values were 0.525, 0.309, and 0.597 consecutively, we also found there were no statistically significant differences between the two groups regarding hemodynamics, arterial blood gases, ventilatory parameters.
Conclusion
We concluded that when utilizing VCV & PCV in OLV in thoracospic surgeries there was no statistically significant difference regarding EVLW score measured by LUS in the ventilated lung.
