Abstract:
BACKGROUND AND AIM
Tonsillectomy is associated with significant pain and post operative pain control is
often unsatisfactory. There have been several methods adopted to treat post operative
pain but none of the methods were effective, with patients continue to undergo
severe postoperative pain. Hence our study aimed at comparing the efficacy of pre
emptive nebulized ketamine versus pre-emptive nebulized lidocaine with the control
group receiving nebulized saline for pain control in children undergoing
tonsillectomy surgeries.
METHODS
In this prospective randomized clinical trial, 105 patients with ASA Ⅰ and Ⅱ
undergoing tonsillectomy surgery were enrolled and randomized into three groups
which are group K, group L, and group C with 35 patients in each group. Patients
in each group received nebulized ketamine, lidocaine and normal saline pre
emptively. Faces pain scale scores, sedation scale scores, and the usage of rescue
analgesia were noted postoperatively for first 6 hours. Hemodynamic parameters
were noted before and after nebulization. The main objective was to find the
number of patients receiving rescue analgesia postoperatively. RESULTS
On comparison of the three groups, rescue analgesia was used less in group K than
groups L and C indicating the efficacy of nebulized ketamine, with only 14.3% of
patients only received rescue analgesia in group K. whereas in group L and group
C, 85.7% and 91.4% patients received rescue analgesia respectively which is
significantly higher compared to group K.
CONCLUSION
Pre-emptive nebulized ketamine was found to be effective in reducing
postoperative pain in children undergoing tonsillectomy
