Background
Percutaneous nephrolithotripsy is a technique used for the treatment of renal stones during which an irrigation fluid is used which may cause hypothermia and shivering if not prevented. The aim of this prospective randomized placebo controlled double blinded study was designed to evaluate the efficacy of preoperative hydrocortisone versus tramadol for attenuation of postoperative shivering after percutaneous nephrolithotripsy under general anesthesia
Method
90 ASA I males and females patients aged 20–50 years, planned for percutaneous nephrolithotripsy under general anesthesia were randomly divided into three groups:
Results
The number of patients who had shivering was statistically significantly higher in S group (12) than in H group (8) and in T group (7) with no statistically significant differences between H and T groups.
Conclusion
Preoperative IV hydrocortisone and tramadol were effective in attenuation of postoperative shivering compared to placebo after percutaneous nephrolithotripsy without increasing the incidence of side effects.
