Purpose: Many factors affecting on hypothermia and shivering during percutaneous nephrolithotomy and in recovery.Hence this study was carried out to determine the effect of irrigation solution temperature on complication of percutaneous nephrolithotomy.
Materials and Methods: In this randomized clinical trial, 60 patients under PCNL in Sina University Hospital were enrolled. The patients were randomly assigned in three groups according to simple random manner. The groups included three groups of room temperature fluid (24 degree), warm solution (37 degree), and cold fluid (20 degree) during nephroscopy.
Results:. Although the initial core temperature was alike across the groups (P > 0.05); The hypothermia rate was occured in all 20 patients in cold fluid group (P=0.012). there was significant difference between groups for final temperature and alteration amount (P=0.001). The mean VAS scores were significantly lower in warm fluid group compared with the others groups at the recovery, and 8 h postoperatively (P = 0.03). Assessment of shivering rates revealed that 3(15%) patients in warm solution group shivered compared with 8 (40%) patients in cold fluid group (P=0.018).
Conclusion: Warm irrigation solution use during PCNL would result in decrease significantly hypothermia, the mean postoperative pain score and shivering. Hence use of warm irrigation fluid for this matter is recommended.
