The study goal was to determine whether the combination of dexamethasone with preemptive analgesia has an additive effect in further improving recovery.
We conducted a prospective, randomized, double-blinded trial of 50 children undergoing tonsillectomy at a university ambulatory surgery center. One study group received 1 intravenous dose of dexamethasone, and another group received 1 dose of saline solution. All patients received tonsillar fossa injections of ropivacaine plus clonidine before tonsil excision.
The 2 study groups were similar in main outcome measurements. Pain intensity and quality of life were not statistically different between the groups. There was a small trend to less trismus and less cumulative codeine use in the steroid group. Overall, there was a very low incidence of nausea and vomiting in both groups, which may have been due to the preemptive analgesia.
Dexamethasone does not significantly improve the morbidity of pediatric tonsillectomy when preemptive analgesia with ropivacaine and clonidine is used concurrently.
