In this survey we have tried to compare the efficacy of %0.5 bupivacaine and %2 lidocaine with normal saline for controlling pain after PCNL. Methods and Materials: In a double blind clinical trial, 60 patients were enrolled being divided into 3 groups. %0.5 Bupivacaine in a dose of 0.5 mg/kg diluted in 20 cc normal saline was injected, into the insertion site and also the tract of the PCNL probe in group one. In our second group, %2 lidocaine (4mg/kg) diluted in 20 cc normal saline, and in the third group, just 20cc NS were injected in the same manner and direction. VAS was measured at 0, 3, 6, 9, 12, 15, and 18 hours post-operatively in order to evaluate pain control. Findings: The mean VAS measured 0, 3, and 6 hours post-operatively in the bupivacaine and lidocaine groups was less than the normal saline group (P<0/05). The average time to injection of the first dose of pethedine was longer in the bupivacaine and lidocaine groups than the normal saline group. (p<0/05). Conclusions: Injection of 0. 5% bupivacaine and %2 lidocaine in the puncture site of PCNL is effective for pain control after PCNL surgery according to our results. }, URL = {http://jap.iums.ac.ir/article-1-13-en.html}, eprint = {http://jap.iums.ac.ir/article-1-13-en.pdf}, journal = {Anesthesiology and Pain}, doi = {}, year = {2013} }
