Brief Summary

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

This study was designed to investigate the effect of position and predictive factors on hypotension in patients performing percutaneous nephrolithotomy. Patients aged \>18 years and ASA I-III who underwent general or regional anaesthesia were included in the study. Percutaneous access was performed in all patients with fluoroscopy in the prone position.

Detailed Description

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

This study was designed to investigate the effect of position and predictive factors on hypotension in patients performing percutaneous nephrolithotomy. Patients aged \>18 years and ASA I-III who underwent general or regional anaesthesia were included in the study. Percutaneous access was performed in all patients with fluoroscopy in the prone position. Age, gender, body mass index(BMI), smoking, type of anaesthesia, duration of anaesthesia and surgery were recorded.

The ECG, SpO2, and non-invasive blood pressure values were recorded intraoperatively. Preoperative and postoperative 12th hour Hb,BUN, Cr,Na,K and Cl were measured in a blood sample. Isotonic was used as an intravenous fluid in all participants. In treatment of hypotension routine ephedrine treatments were recorded.

In the literature, studies in PCNL surgery have focused on data such as method, duration of bleeding and fluoroscopy, electrolyte-metabolic changes, and complications such as fever, hypothermia, pleural damage, and hospital stay. A limited number of studies have focused on bleeding and hemodynamics in comparing surgical methods in the prone and supine positions. the investigators could not find any study comparing systemic disease effects on intraoperative hypotension (hemodynamic parameters) in Prone PCNL surgery.
