Effect of Tegileridine Versus Sufentanil as Analgesic Components on Opioid-Induced Cough During Anesthesia Induction

July 7, 2026 updated by: The First People's Hospital of Lianyungang

The Affiliated Lianyungang Hospital of Xuzhou Medical University

In patients undergoing general anesthesia with planned tracheal intubation , a prospective, randomized, controlled study was conducted to record the occurrence of cough 2 minutes after injection of Sufentanil or Tegilerdine. The cough was graded based on the frequency and duration: Grade I, no cough; Grade II, a single mild cough; Grade III, multiple coughs with duration <1 second; Grade IV, continuous coughing with a duration >15 seconds.

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

Using a computer-generated randomized number table, patients were divided into two groups: the experimental group receiving Tiliglitidine (T group) at 20-50ug/kg, and the control group receiving Sufentanil (S group) at 0.2-0.4 μg/kg. After patients arrived in the operating room, routine monitoring including non-invasive blood pressure, electrocardiogram, and oxygen saturation was performed, and intravenous access was established. Patients were oxygenated and given the study drug before anesthesia induction. No other drugs were administered to the patients before giving the study drug. During anesthesia induction, patients received intravenous injection of Tiliglitide or Sufentanil according to their group. The severity of coughing was graded based on the number of coughing episodes: graded by the number and duration of coughs: Grade I, no cough, breathing regular; Grade II, a single mild cough; Grade III, multiple coughs, lasting less than 15 seconds; Grade IV, continuous coughs, lasting more than 15 seconds.

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

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Age between 18 and 65 years, 18 ≤ BMI (kg/m²) ≤ 30;

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
Incidence of choking cough response
Time Frame: 2 minutes after administration
Two minutes after administration of the study drugs (Tegilerdine/Sufentanil), any clear coughing action is considered an 'occurrence'.
2 minutes after administration

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
Grading of choking and coughing response
Time Frame: 2 minutes after administration
Grading based on the number and duration of coughs: Grade I, no coughing, breathing is even; Grade II, a single mild cough; Grade III, multiple coughs lasting less than 15 seconds; Grade IV, continuous coughing lasting more than 15 seconds
2 minutes after administration
