In the decades following the introduction of percutaneous nephrolithotomy (PCNL), urology specialists have proposed modifications to improve the safety and efficacy of this procedure. The present study aimed to compare the two methods of supine and prone positioning with different doses of Marcaine on the amount of hemorrhage in percutaneous renal stone removal with spinal anesthesia.
This clinical trial study was performed on 200 patients (50 patients each) between the ages of 20-60 years who had Class I and II Anesthesia (ASA) and were candidates for Percutaneous Nephrolithotripsy Surgery in peimanieh Hospital in 1977, done. Patients were divided into four groups (fentanyl-Marcaine and Marcaine) in supine and prone. Bleeding rate was measured in each group. Data were analyzed using SPSS software version 21 and descriptive and inferential statistics.
There was no statistically significant difference between the supine and prone positioning methods with different doses of Marcaine in terms of age (p = 0.390). The two methods of supine and prone positioning were also matched by different doses of Marcaine in terms of sex and class of anesthesia. In group A, 32% of patients had 50 cc and 22% had 100 cc.
