Median Effective Dose of Cisatracurium for the Prevention of Fasciculation Caused by the Injection of Succinylcholine
A study testing Cisatracurium in people with Fasciculation and Succinylcholine, run by Yangzhou University at 1 site in China.
Trial summary
Succinylcholine is currently the only depolarizing neuromuscular blocker widely used in anesthesia induction and is the drug of choice for rapid sequential anesthesia induction. However, with succinylcholine, varying degrees of muscle fibrillation and muscle pain occur. Read more about this study

About this study
Succinylcholine is currently the only depolarizing neuromuscular blocker widely used in anesthesia induction and is the drug of choice for rapid sequential anesthesia induction. However, with succinylcholine, varying degrees of muscle fibrillation and muscle pain occur. Intravenous injection of succinylcholine caused by myomuscular fibrillation can cause increased intragastric pressure, intraocular pressure and intracranial pressure, increased serum potassium and postoperative myalgia, increased the incidence of adverse events such as needle prolapse, extravasation of injected drugs, and reduced perioperative comfort of patients. Pretreatment with cisatracurium provides limited prevention of muscular fibrillation due to succinylcholine, but the choice of dose often depends on user experience, and there have been no previous studies of age-related doses of cisatracurium for the prevention of muscular fibrillation caused by succinylcholine, and its half-effective amount (ED50) has not been established. In this study, patients treated with elective general anesthesia surgery were the subjects, and in the process of general anesthesia induction, cis-atracurium was pretreated to evaluate the degree of inhibition of muscular fibrillation caused by succinylcholine, and half of the effective dose of cis-atracurium inhibition of muscular fibrillation caused by succinylcholine was calculated by sequential method.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CisatracuriumDrug
Advanced intravenous injection of cisatracurium before the succinylcholine injection
| Study group | Role | What they receive |
|---|---|---|
| Age range of 18 to 44 years olds | Experimental | The initial dose of cisatracurium for pre-injection was set at 0.015mg/kg according to previous literature and preliminary test results. The dose of cisatracurium was according to the patients' fasciculation level. If there is no fasciculation (negative reaction), the dose of cisatracurium in the next patient will be reduced until the patient has fasciculation. If there is fasciculation (positive reaction), the dose of cisatracurium will be increased in the next patient until the patient has no fasciculation. Receives: Drug: Cisatracurium |
| Age range of 45 to 59 years olds | Experimental | The initial dose of cisatracurium for pre-injection was set at 0.015mg/kg according to previous literature and preliminary test results. The dose of cisatracurium was according to the patients' fasciculation level. If there is no fasciculation (negative reaction), the dose of cisatracurium in the next patient will be reduced until the patient has fasciculation. If there is fasciculation (positive reaction), the dose of cisatracurium will be increased in the next patient until the patient has no fasciculation. Receives: Drug: Cisatracurium |
| Age range of 60 to 80 years olds | Experimental | The initial dose of cisatracurium for pre-injection was set at 0.015mg/kg according to previous literature and preliminary test results. The dose of cisatracurium was according to the patients' fasciculation level. If there is no fasciculation (negative reaction), the dose of cisatracurium in the next patient will be reduced until the patient has fasciculation. If there is fasciculation (positive reaction), the dose of cisatracurium will be increased in the next patient until the patient has no fasciculation. Receives: Drug: Cisatracurium |
What is being measured
The primary outcome is the main question the study is designed to answer.
The appearance of fasciculation Yes or No
Yes or No
Measured: an average of 2 minutes
The levels of fasciculation
Fasciculation after the administration of medications was examined and graded by an anesthesiologist using four-point Likert scale: Grade 0 = no fasciculation; Grade 1 = mild, fine fasciculations of the eyes, neck, face, or fingers, without limb movement; Grade 2 = moderate fasciculations occurring at more than two sites or obvious limb movement; and Grade 3 = vigorous or severe, sustained, and widespread fasciculations in the trunk and limbs.
Measured: an average of 2 minutes
