The Effect of Tranexamic Acid in Endoscopic and Microscopic Ear Surgery Cases on Surgeon Satisfaction

September 2, 2025 updated by: Talha Ersoy, TC Erciyes University

The Effect of The Use of Low Dose Tranexamic Acid on Surgeon Satisfaction, Side Effects and Complications in Endoscopic and Microscopic Ear Surgery Cases Which Are Used With Controlled Hypotension

By using tranexamic acid, an antifibrinolytic drug, the aim is to prevent the restriction of the field of view of the surgical field due to bleeding in middle ear microscopic and endoscopic surgery operations in which controlled hypotension is applied, and therefore the prolongation of the surgical time, and to increase surgeon satisfaction.

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After obtaining approval from our university and the Turkish Ministry of Health's pharmaceutical and medical device agency and written consent from the patients, 100 patients who underwent middle ear surgery using controlled hypotension under general anesthesia will be included in the study.

The study will be conducted in a randomized controlled, double-blind manner. Patients between the ages of 18-65 and with American Society of Anesthesiologists (ASA) Scores I and II will be included in the study. Patients will be divided into two groups: Intervention (M) and Control (C). Just before the operation begins, 10 mg/kg tranexamic acid (TXA) will be administered to the intervention group in 100 mL of 0.9% physiological saline (SF) solution in 15 minutes. 100 mL of 0.9% SF solution will be sent to the control group in 15 minutes. At the end of the operation, the operator's quality of vision of the surgical field will be recorded by questioning the surgeon's satisfaction with the Boezaart Score and the Surgeon Satisfaction Score.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Inclusion Criteria:

  • Individuals between the ages of 18-65
  • Individuals with ASA I (no additional disease) or ASA II (mild systemic disease)
  • Those who do not have a disease such as thrombophilia or bleeding diathesis will be included in the study

Exclusion Criteria:

  • Patients with ASA III (those with uncontrolled chronic disease) or above

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Intervention Group (I)
Patients' vital values will be recorded before surgery.10 mg/kg tranexamic acid (Transamine 10% IV/IM Solution for Injection) is added into 100 cc serum through the appropriate vascular access and injected for 15 minutes.The amount of bleeding in the surgical field will be evaluated by the surgeon using the Boezaart Scale.Intraoperatively, hemodynamic changes such as bradycardia, tachycardia, arrhythmia and agents used such as vasopressors, antiarrhythmics and vagolytics will be recorded in the patient.Post-Operatively the surgeon's quality of vision will be questioned with the Surgeon Satisfaction Scale.Postoperative 0th, 12th, and 24th developments - the presence of vomiting and postoperative complaints will be questioned.The presence of bleeding or complications in the first 2 weeks after surgery will be questioned.The presence of thromboembolic events and other services will be questioned within 12 weeks after surgery.

Intraoperatively, hemodynamic changes such as bradycardia, tachycardia, arrhythmia that develop in the patient, and agents such as vasopressors, antiarrhythmics, and vagolytics used will be recorded.

Postoperatively the surgeon's quality of vision will be questioned with the Surgeon Satisfaction Scale. The presence of nausea and vomiting and postoperative complaints will be questioned at the 0th, 12th, and 24th postoperative hours.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Boezaart et al grading scale
Time Frame: 2-3 hours

At the end of a surgery, the surgical field was graded in terms of bleeding by the surgeon using the scale used by Boezaart et al in 1995;

0 : No bleeding (cadaveric conditions).

  1. : Slight bleeding: no suctioning required.
  2. : Slight bleeding: occasional suctioning required.
  3. : Slight bleeding: frequent suctioning required. Bleeding threatens surgical field a few seconds after suction is removed.
  4. : Moderate bleeding: frequent suctioning required and bleeding threatens surgical field directly after suction is removed.
  5. : Severe bleeding: constant suctioning required; bleeding appears faster than can be removed by suction; surgical field severely threatened and surgery usually not possible.
2-3 hours
Surgeon Satisfaction Score
Time Frame: 2-3 hours
At the and of surgery , surgeon's satisfaction with surgical field quality was also graded in a 5-item Likert scale, where 1 = poor and 5 = excellent
2-3 hours
