Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A total of 40 ASA (American Society of Anesthesiology) physical status I-III who underwent lumbar disc hernia repair for one or two levels were included in this prospective study. A standard anesthesia protocol was performed in all patients. Routine intraoperative monitoring consisted of electrocardiography, automatic noninvasive arterial blood pressure, pulse oximetry, capnography, and cerebral tissue oxygen saturation through NIRS.Patients' demographics such as age, gender, height, weight, BMI, smoking status and pre-existing medical conditions were recorded.The patients were allocated equally to two groups according to BMI as Group I: BMI ≥30kg/m2,Group II \<30 kg/m2.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Routine intraoperative monitoring consisted of electrocardiography, automatic noninvasive arterial blood pressure, pulse oximetry, capnography, and cerebral tissue oxygen saturation through NIRS.Frontal lobe oxygenation was monitored continuously and recorded every 5 minutes.Before positioning patients on the operating table, a Foley catheter was placed. IAP was measured in the following positions in all patients: 1) in the supine position after intubation 2) in the prone position before the skin incision.All patients were placed into the prone position on the silicone pads after general anesthesia.Before statistical analysis, the 40 patients were allocated equally to two groups according to the World Health Organization Guideline of BMI: Group I: BMI ≥30kg/m2, Group II \<30 kg/m2
