POSTOPERATIVE ATELECTASIS, PULMONARY INFECTION
In neurosurgery, due to the long-term use of general anesthesia and postoperative bed rest, the risk of postoperative atelectasis and pulmonary infection is increased [Optimization of the ventilation strategy can minimize iatrogenic injury in previously healthy lungs, reducing the incidence of PPCs [Electrical impedance tomography (EIT) has been used as a noninvasive, radiation-free, bedside technique for assessing the regional distribution of pulmonary ventilation and perfusion and has a good correlation with computed tomography (CT) and X-ray [Considering the feasibility and usefulness of these methods, we investigated whether the lowest DP could contribute to the postoperative homogeneous aeration using EIT and LUS.
