Summary

The effect of driving pressure (DP)-guided positive end expiratory pressure (PEEP) on early postoperative pulmonary ventilation is to be determined for patients undergoing neurosurgery. Patients are recruited to receive volume controlled ventilation with either a fixed PEEP (5cmH2O) or DP titrated PEEP. Early postoperative regional distribution of lung ventilation, expressed as global inhomogeneity (GI) is evaluated by electrical impedance tomography (EIT), a noninvasive, radiation free modality. Center of ventilation (COV) by EIT, as well as the lung ultrasonography（LUS), perioperative ventilatory parameters, arterial oxygenation index (PaO2/FiO2) , serum indicators and postoperative pulmonary complications are secondary outcome variables.

Conditions

  • Neurosurgery

Interventions

PROCEDURE

PEEP

Driving pressure (DP) is calculated as "plateau pressure - PEEP". 10min after position adjustment, PEEP is increased from 2 to 10 cm H2O incrementally. Each PEEP level is maintained for 10 respiratory cycles, with DP in the last cycle recorded. Then the PEEP level producing the lowest DP will be identified and maintained intraoperatively.
