Postoperative Complications Following Skull Base Tumor Resection

Condition(s) studied

Investigational drug(s) / intervention(s)

Pulmonary ultrasound examination: All ultrasound scans were performed by the same anaesthetists. Pulmonary ultrasound examination was performed at two time points for each patient: 20 min before starting mechanical ventilation of the lungs when patients were placed in the supine position(preoperative), 20 min after after surgery end at the time the patient was placed in the supine position (postoperative), before Intubation and after extubation Patientswere scanned in the supine position following the pulmonary ultrasound examination method The thorax was divided by the anterior axillary line, the posterior axillary line, and a horizontal line beneath nipple. Twelve intercostal spaces of each area were scanned and analysed. Aeration loss was assessedby calculating the modified LUS score that is calculated mainly using the amount of B-line The pulmonary ultrasound score of the hemithorax (0-18).

Study summary

The skull base tumor is located in the deep intracranial layer and is closely related to the brain stem and intracranial nerves. The incidence of postoperative complications after skull base tumor resection is high. Therefore, the perioperative management of skull base tumor resection is challenging.

Eligibility

Primary outcome measure(s)

• The incidence of postoperative pulmonary complications — Postoperative 7 days
  The primary outcome was the incidence of a composite endpoint of postoperative pulmonary complicationswithin 7 days after surgery. Postoperative pulmonary complications was considered to have occurred if at least one postoperative pulmonary event was observed, such as the pneumonia, pleural effusion, respiratory failure, hypoxemia, pneumothorax, atelectasis of the lung, bronchospasm..Ultrasound scans were performed at 20 min before starting mechanical ventilation of the lungs (before intubation) and performed at 20 min after surgery (after extubation)
