NCT07188779

Brief Summary

The purpose of the research is to determine if RADA16 (also known as PuraStat®, PuraGel®, or PuraSinus®) improves patient outcomes following pediatric tonsillectomy procedures. Researchers will compare application of device RADA16 to application of no device to see if RADA16 works to treat post tonsillectomy hemorrhage.Participants will: Undergo tonsillectomy procedure. Receive and fill out a survey sent via email every 2 days following their procedure for 15 days, plus an additional survey on day 30, and track their symptoms.

Outcome Measures

Primary Outcomes (1)

  • Postoperative pain

    Pain assessed via the Wong Baker Faces scale. The primary outcome measure will be assessed via online survey on post-operative day one then subsequently every other day until post-operative day fifteen, with a final survey on day 30.

    From enrollment to post-operative day 30.

Secondary Outcomes (5)

  • Number of Participants with post-tonsillectomy hemorrhage who receive topical agents

    From enrollment to post-operative day 30

  • Number of Participants with post-tonsillectomy hemorrhage who require a return to the operating room

    From enrollment to post-operative day 30

  • Number of participants who require hospital readmission for post tonsillectomy hemorrhage management

    From enrollment to post-operative day thirty

  • Number of participants who require a rescue analgesic for management following tonsillectomy procedure

    From enrollment to post-operative day 30

  • Days participants take to resume their regular diet post operation

    From enrollment to post-operative day 30

Study Arms (2)

RADA16

ACTIVE COMPARATOR

Patients randomized to the treatment arm will undergo application of 2.5% RADA16 hydrogel to the tonsillar fossae following tonsillectomy using a sterile syringe tip applicator. The gel will be spread into a thin layer within the tonsillar fossae. The gel will be left to sit for 60 seconds. A suction device will then be used to remove any excess RADA16 hydrogel, leaving a thin layer of RADA16 over the tonsillar fossae.

Device: RADA16 hydrogel

Control arm

NO INTERVENTION

Patients randomized to the control arm will not undergo application of RADA16 hydrogel following hemostasis with suction monopolar electrocautery.

Interventions

Application of 2.5% RADA16 hydrogel to the tonsillar fossae following tonsillectomy using a sterile syringe tip applicator. The gel will be spread into a thin layer within the tonsillar fossae. The gel will be left to sit for 60 seconds. A suction device will then be used to remove any excess RADA16 hydrogel, leaving a thin layer of RADA16 over the tonsillar fossae.
