ED90 of Tegileridine Combined With Propofol for LMA Insertion
18. juni 2026 opdateret af: Shiyou Wei
90% Effective Dose of Tegileridine Combined With Propofol for Inhibiting Laryngeal Mask Airway Insertion Responses in Patients of Different Ages: A Biased-Coin Sequential Allocation Dose-Finding Study
This is a prospective two-group dose-finding trial using biased-coin sequential up-and-down design.
We plan to enroll 108 patients who need general anesthesia with laryngeal mask airway placement, divided into young group (18-65 years old) and elderly group (65 years old and older).
All patients will receive tegileridine combined with fixed-dose propofol for anesthesia induction.
The main goal is to find the 90% effective dose (ED90) of tegileridine that can fully block body movement, cough, tearing and unstable blood pressure/heart rate during laryngeal mask insertion.
We will also record cough rate, hemodynamic changes, sedation depth and all perioperative adverse reactions to provide safe dosing reference for different age patients in clinical anesthesia.

Eksperimentel: Single Group (All Adult Patients Aged ≥18 Years)
All enrolled adult patients aged ≥18 years receive intravenous tegileridine followed by fixed-dose propofol 2 mg/kg for anesthesia induction.
This single-group biased-coin sequential up-and-down design starts with an initial tegileridine dose of 10 μg/kg, with 1 μg/kg dose step for increment or decrement based on laryngeal mask airway insertion response.
Patients are stratified into young subgroup (18-65 years) and elderly subgroup (≥65 years) for separate ED90 calculation.
Intraoperative anesthesia maintenance and perioperative supportive treatments are consistent for all subjects.

Intravenous tegileridine with variable dose adjusted by biased-coin sequential design, combined with fixed-dose propofol 2 mg/kg for general anesthesia induction before laryngeal mask airway placement.

90% Effective Dose (ED90) of Tegileridine for Suppressing Laryngeal Mask Airway Insertion Response
Tidsramme: Within 3 minutes after laryngeal mask airway insertion
|
The 90% effective dose of intravenous tegileridine combined with fixed-dose propofol to completely inhibit positive responses during laryngeal mask airway insertion, calculated via central ordinal regression with 95% confidence interval.
Positive response is defined as any body movement, frowning, tearing, cough, or blood pressure/heart rate increase over 20% compared with baseline within 3 minutes after LMA placement.

|
Incidence of cough during laryngeal mask airway insertion
Tidsramme: From the start of anesthesia induction to 3 minutes after the end of laryngeal mask airway insertion
|
During anesthesia induction, intravenous injection of opioids may cause coughing.
During the after laryngeal mask airway insertion process, coughing may occur due to airway stimulation.

From the start of anesthesia induction to 3 minutes after the end of laryngeal mask airway insertion

Success rate of sedation
Tidsramme: From the start of intubation to 3 minutes after the end of laryngeal mask airway insertion
|
The modified observer's assessment of alert/sedation scale (MOAA/S) is a commonly - used sedation evaluation tool in clinical practice.
It classifies reactivity under different stimuli: Grade 5 means a sensitive response to calling the name in a normal tone of voice; Grade 4 indicates a sluggish response to calling the name in a normal tone of voice; Grade 3 requires a loud or repeated call of the name to elicit a response; Grade 2 shows a response to slight pushing and vibration; Grade 1 has a response to a painful stimulus (by squeezing the trapezius muscle area); Grade 0 means no response to a painful stimulus.
Moreover, MOAA/S ≤ 2 indicates loss of consciousness, which can assist medical staff in judging the sedation level and consciousness state of patients.
