[Effects of bupivacaine versus lidocaine infiltration on postoperative analgesia in pediatric tonsillectomy patients].

Abstract

OBJECTIVE:

To compare the effects of bupivacaine, lidocaine and saline injections in alleviating post tonsillectomy pain.

METHOD:

We recruited 60 patients into the study. All subjects were randomly allocated into 3 groups. Group 1 received 0.9% sodium chloride (saline group), group 2 received 0.25% bupivacaine (bupivacaine group) and group 3 received 2% lidocaine (lidocaine group), infiltrated around each tonsil. Pain was evaluated with McGrath's face scale.

RESULT:

The postoperative pain scores at 2 and 6 hours were similar among the groups (P>0.05). The pain scores in the bupivacaine group were lower than those in the saline group at 12 h (P<0.05). The pain scores in the bupivacaine and lidocaine groups were significantly lower than those in the saline group from 18 to 24 hours until day 7 (P<0.05). There was no difference between the bupivacaine and lidocaine groups (P> 0.05).

CONCLUSION:

Local infiltration of bupivacaine is a relatively and safe effective method and is equivalent to use of lidocaine for post tonsillectomy pain.
