Clinical Trial Summary

Tonsillectomy is one of the most commonly performed surgical procedures in the United States. The primary indications for tonsillectomy in the adult population include recurrent pharyngitis, chronic tonsillitis, and obstructive pathology. Tonsillectomy is often associated with severe postoperative pain, which can result in prolonged poor oral intake, dehydration, and the need for high dose narcotics. In severely dehydrated patients, epithelial shedding and necrosis of soft tissues at the surgical site can lead to postoperative complications such as bleeding, delayed healing, and severe pain. The goal for this study is to explore the use of a long acting local anesthetic bupivacaine liposome injectable suspension (Exparel) to manage pain experienced by adult patients after tonsillectomy

Description:

The proposed investigation will examine whether Exparel (bupivacaine liposome injectable suspension 1.3%-13.3 mg/mL) when used as a post-excision adjunct to the standard of care bupivacaine HCl 0.25% (2.5 mg/mL) with Epinephrine (5mcg/mL), will decrease the patient's post-tonsillectomy experience of pain intensity, especially for the first three days after surgery, and correspondingly reduce the requirement for pain medications and improve outcomes.

Intervention

Drug:
• Adjunct Exparel (bupivacaine liposome suspension 1.3%)
After removal of the tonsils and before extubation, the principal investigator will infiltrate 0.5 mL of the standard of care medication-bupivacaine HCl 0.25% (2.5 mg/mL) with epinephrine (5 mcg/mL) i.m.-into the upper and lower poles of the anterior and posterior tonsillar pillars on the right and left side of the oropharynx for a volume of 2 mL of bupivacaine HCl on each side. Following the standard medication, the principal investigator will infiltrate 0.5 mL of adjunct Exparel (bupivacaine liposome suspension 1.3% [13.3 mg/mL] i.m.) into the upper and lower poles of the anterior and posterior tonsillar pillars on the right and left side of the oropharynx for a volume of 2 mL of bupivacaine liposome injectable suspension 1.3% (13.3 mg/mL) on each side.

Other:
• Standard Care
After removal of the tonsils and before extubation, the principal investigator will infiltrate 0.5 mL of the standard of care medication-bupivacaine HCl 0.25% (2.5 mg/ mL) with epinephrine (5 mcg/mL) i.m.-into the upper and lower poles of the anterior and posterior tonsillar pillars on the right and left side of the oropharynx for a volume of 2 mL of bupivacaine HCl on each side.
