Ketodex Versus Ketofol in Adolescent Gastrointestinal Endoscopy

August 4, 2026 updated by: Dilek Yeniay, Giresun University

The Effect of Anesthesia Protocols Used in Gastrointestinal Endoscopy Procedures in Adolescents on the Outcome

Gastrointestinal endoscopic procedures in adolescents require effective sedoanalgesia to ensure procedural comfort and prevent agitation. Pain control is an essential component of these procedures, and current practice commonly involves low-dose combinations of anesthetic agents. Sedoanalgesia protocols are selected according to patient characteristics and the anesthesiologist's clinical experience. This prospective observational study aims to compare the effects of ketodex and ketofol on intraoperative procedural comfort, postoperative recovery, and patient satisfaction in adolescents undergoing gastrointestinal endoscopy.

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

Gastrointestinal endoscopic (GE) procedures require the use of sedoanalgesic agents to ensure patient comfort and procedural safety. In adolescent patients, deep sedation is often necessary to provide adequate procedural comfort and to prevent agitation. Additionally, GE procedures are inherently painful and require the use of analgesic medications as part of routine practice. The scientifically accepted approach involves the use of low-dose combinations of different anesthetic agents. The selection of the sedoanalgesia protocol during the procedure is shaped by patient characteristics as well as the experience and preference of the attending anesthesiologist.

The aim of this study is to evaluate the effects of routinely used sedoanalgesia protocols, specifically ketodex and ketofol, on intraoperative procedural comfort, postoperative recovery, and patient satisfaction in adolescent patients undergoing gastrointestinal endoscopy.

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

  • Child
  • Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adolescent patients scheduled to undergo gastrointestinal endoscopic procedures under sedation as part of routine clinical care will be included in the study. Patients will receive either ketamine-dexmedetomidine (ketodex) or ketamine-propofol (ketofol) sedation according to standard institutional practice and the preference of the attending anesthesiologist.

Description

Inclusion Criteria:

ASA I-II, adolescents aged 10-18 years undergoing elective gastrointestinal endoscopic procedures

Exclusion Criteria:

  • Emergency cases
  • Children under 10 years of age
  • Children with mental retardation
  • Children whose parents refuse to participate in the study and children who do not consent to participate themselves
  • Children with known allergy, hypersensitivity, intolerance or contraindication to any of the sedoanalgesic drugs used

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
Intraoperative patient comfort assessed by Ramsey Sedation Scale
Time Frame: During the intraoperative period

Intraoperative patient comfort was evaluated using the Ramsey Sedation Scale, a 6-point clinical scale assessing the level of sedation and patient responsiveness.

The scale ranges from 1 to 6, where lower scores indicate agitation or anxiety and higher scores indicate deeper sedation and better patient comfort.
During the intraoperative period
Intraoperative additional anesthetic drug requirement
Time Frame: During the intraoperative period

The requirement for additional anesthetic medication administered during the intraoperative period was recorded.

Additional anesthetic use was determined based on clinical signs of inadequate sedation or patient discomfort as judged by the attending anesthesiologist.
During the intraoperative period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Postoperative recovery time assessed by recovery score
Time Frame: From the end of surgery until discharge from the postanesthesia care unit, assessed up to 24 hours postoperatively.

Postoperative recovery time was assessed using a standardized recovery score evaluating the patient's level of consciousness and readiness for discharge from the postanesthesia care unit.

Higher scores indicate better recovery status.
From the end of surgery until discharge from the postanesthesia care unit, assessed up to 24 hours postoperatively.
Emergence agitation assessed by emergence agitation score
Time Frame: From the end of anesthesia until discharge from the postanesthesia care unit, assessed up to 24 hours postoperatively.

Emergence agitation was evaluated using a validated emergence agitation scoring system.

The scale assesses the severity of agitation during emergence from anesthesia, with higher scores indicating greater levels of agitation.between the ketodex and ketofol groups during the procedure
From the end of anesthesia until discharge from the postanesthesia care unit, assessed up to 24 hours postoperatively.
