Journal of Anesthesiology and Pain

Aim and Background:

Controlling pain in the post-operative period is still one of the

challenging issues for anaesthesiologists as it tremendously helps patients to return to their daily

life as soon as possible. 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.
