Abstract

Purpose

The objective of this study was to compare the efficacy of peritonsillar and glossotonsillar sulcus infiltration with bupivacaine to manage postoperative pain and odynophagia in children undergoing tonsillectomy.

Methods

Fifty children (5–10 years of age) undergoing tonsillectomy due to recurrent tonsillar infections were enrolled in the study and assigned into two groups receiving either pre-incisional peritonsillar (Group 1, n = 25) or glossotonsillar sulcus (Group 2, n = 25) infiltration with 1 mg/kg bupivacaine (0.5%) totaling 5 mL in volume. At different time intervals following arrival to the post-anesthesia care unit (PACU), the participants in each group were evaluated for pain using the modified Children’s Hospital of Eastern Ontario Pain Scale (mCHEOPS) and for odynophagia using a four-point scale (1—none, normal or no difficulty with swallowing, 2—mild, mild difficulty with swallowing, 3—moderate, moderate difficulty with swallowing, and 4—severe, no swallowing or swallowing only with maximal effort). Additional parameters were assessed for 24 h post-surgery, including time to first administration of analgesic, additional analgesic requirements, nausea/vomiting, allergic reaction, and bleeding.

Results

Infiltration of either region with bupivacaine yielded similar analgesic effects at different times following the surgery (P = 0.065). Time to first analgesic treatment and additional analgesic requirements were not significantly different between groups (P = 0.181). Compared to the Group 1, Group 2 was associated with significantly lower odynophagia scores at different times after the surgery (P = 0.020).

Conclusion

Present results indicate that the infiltration of local anesthetics to glossotonsillar sulcus is a safe, practical, and effective pain management intervention without risk of significant side effects for children undergoing tonsillectomy.
