NCT07675278

Brief Summary

The goal of this quasi-experimental study is to compare the effectiveness of topical adrenaline and 3% hydrogen peroxide for controlling bleeding (hemostasis) during tonsil removal surgery in patients aged 5 to 18 years. The main questions it aims to answer are: 1. Which substance leads to faster bleeding control during surgery? 2. Which substance results in less total blood loss during surgery? Researchers compared the adrenaline group to the hydrogen peroxide group to see if one agent was more effective at managing bleeding than the other. Participants underwent a tonsillectomy where surgeons applied either gauze soaked in adrenaline (1:100,000 solution) or gauze soaked in 3% hydrogen peroxide to the tonsil area to stop bleeding.

Outcome Measures

Primary Outcomes (2)

  • Severity of intraoperative blood loss during tonsillectomy as classified by combined gravimetric and volumetric assessment.

    Total volume of blood lost during the surgical procedure, determined by the sum of blood volume calculated from the gravimetric method (pre- and post-operative weight of surgical gauze) and the volumetric method (suction canister volume). Results are categorized ordinally as: Mild (16-75 mL), Moderate (76-275 mL), or Severe (\>275 mL).

    Measured during the intraoperative period, specifically from the time of hemostatic agent application until the completion of the tonsillectomy procedure.

  • Time to achieve intraoperative hemostasis during tonsillectomy as measured in minutes.

    Time from the application of the hemostatic agent until the complete cessation of bleeding from the tonsillar fossa, as recorded by the surgical team. Time is recorded in categorical intervals: \<1 minute, 1-3 minutes, 3-5 minutes, and \>5 minutes.

    Measured during the intraoperative period, specifically from the time of hemostatic agent application until the completion of the tonsillectomy procedure.

Study Arms (2)

Adrenaline Group

ACTIVE COMPARATOR

Participants in this group receive topical application of adrenaline (1:100,000 solution) via gauze pieces immediately following the removal of tonsils during the surgical procedure to achieve hemostasis.

Drug: Adrenaline

Hydrogen Peroxide Group

ACTIVE COMPARATOR

Participants in this group receive topical application of 3% hydrogen peroxide via gauze pieces immediately following the removal of tonsils during the surgical procedure to achieve hemostasis.

Drug: Hydrogen Peroxide

Interventions

Topical application of 3% hydrogen peroxide solution.

Also known as: H2O2
Hydrogen Peroxide Group

Topical application of 1:100,000 adrenaline solution.

Also known as: Epinephrine
Adrenaline Group

OUTCOMES ASSESSOR
Masking Details
The study utilized a single-blind design regarding the assessment of outcomes. Personnel responsible for evaluating intraoperative blood loss, including those weighing gauze and reading the suction canister volumes, were blinded to the group assignment of the participants. However, the operating surgeons and the surgical team were not masked, as they were required to know which hemostatic agent was being applied during the procedure to perform the intervention and record the time to hemostasis. Therefore, neither the participants, the care providers, nor the primary investigators were masked.

Intervention Model
PARALLEL
Model Details: The study employs a parallel group design with two distinct study arms: Group A (adrenaline) and Group B (hydrogen peroxide). Participants are assigned to one of these two groups based on their date of surgery-even-numbered dates for the adrenaline group and odd-numbered dates for the hydrogen peroxide group-and receive only their assigned intervention for the duration of the procedure.
