Study Details

Study Description

Brief Summary

The objective of this study is to determine if there is a difference in post-operative pain after septorhinoplasty when long-acting liposomal bupivacaine is used for local anesthesia compared to other standard local anesthetic regimens.

Condition or Disease	Intervention/Treatment	Phase
Rhinoplasty Pain Management	Drug: Liposomal Bupivacaine Drug: 0.25% bupivacaine with 1:200,000 epinephrine Other: Placebo - Saline solution	Phase 3

Detailed Description

Hypothesis: Patients receiving postoperative liposomal bupivacaine (EXPAREL®) at the surgical site after their septorhinoplasty will have better postoperative pain control and require fewer narcotics by means of a lower MME compared to the placebo group and the group that receives postoperative 0.25% bupivacaine with 1:200,000 epinephrine.

This a prospective randomized controlled, double-blind study evaluating the efficacy of EXPAREL® versus plain bupivacaine HCl and placebo after perinasal injections during septorhinoplasty procedures. Seventy-two total patients undergoing septorhinoplasty will be randomly distributed into three groups (20 patients per group) with various postoperative local anesthesia regimens. All groups will be given standard oral postoperative pain regimens as prescribed by the primary surgeon, typically consisting of alternating doses of 1000 mg acetaminophen and 800 mg ibuprofen with oxycodone 5 mg every 6 hours as needed for breakthrough pain. All three groups will receive the same treatment at the beginning of surgery with pre-incisional local surgical site injections with perinasal blocks of 1% lidocaine with 1:100,000 epinephrine. Group one (study group) will receive a five mL injection of EXPAREL® postoperatively, group two will receive a five mL injection of 0.25% bupivacaine with 1:200,000 epinephrine postoperatively, and group three will receive a five mL injection of saline along the surgical site, all in a ring block fashion (see illustration). This ring block involves nerve blocks to nasal branches of the supratrochlear, infraorbital, and infratrochlear nerves. This will also be injected into the floor of the nasal cavity to block branches of the nasopalatine nerve. The remainder of the ring block targets local infiltration surrounding the nose and injections are over bone. Although there is a potential risk of diffusion to adjacent cartilage, this risk is predicted to be low. Their use of postoperative pain medications will then be documented in the immediate postoperative period in the post-anesthesia care unit (PACU) as well as the following week postoperatively, every day, for three times a day. All groups will be required to fill electronic pain journals through RedCap (a HIPPA compliant server) to record consumption of pain medications and pain levels as reported by visual analog pain scales, the Wong-Baker FACES pain rating scale, and modified McGill pain questionnaire, all of which are validated tools for pain assessment. Patients will be subsequently followed over the course of six months postoperatively with these validated measures, use of pain medication, and by clinical exam of the nose/injection site including both external and internal nasal exam, palpation of the nose and cartilage grafts, evaluation static and dynamic function of the nose, and the presence of any adverse outcomes including but not limited to cartilage graft loss, septal perforation, synechiae formation, infection, and persistent or worsening nasal obstruction.

Study Design

Study Type:

Interventional

Anticipated Enrollment :

72 participants

Allocation:

Randomized

Intervention Model:

Parallel Assignment

Intervention Model Description:

This will be a randomized controlled, double-blinded study.This will be a randomized controlled, double-blinded study.

Masking:

Triple (Participant, Care Provider, Investigator)

Masking Description:

The patient, surgeons, and research team will be blinded to the group that the subject was randomized to. The pharmacy will prepare equivalent drugs for each study group to visually appear similar so that blinding can be maintained. In the event if the patient experiences a concerning or an adverse reaction, the patient, the surgeons and the research team will be immediately unblinded from the study. If unblinding is required, the pharmacy will be notified and then will provide, from the randomization list, information as to which study group the patient was assigned.
