Median Effective Dose of Esketamine Pretreatment to Prevent Sufentanil-induced Cough
A study testing Esketamine in people with Sufentanil and Esketamine, run by Yangzhou University.
Trial summary
Sufentanil has the advantages of fast onset time, strong analgesic function and cardiovascular stability, and is widely used during general anesthesia induction. However, sufentanil can cause cough during induction of general anesthesia. Read more about this study

About this study
Sufentanil has the advantages of fast onset time, strong analgesic function and cardiovascular stability, and is widely used during general anesthesia induction. However, sufentanil can cause cough during induction of general anesthesia. Different studies have reported that the incidence of sufentanil-induced cough ( SIC ) during anesthesia is 16-42 %. This pathological condition may lead to damage to the central nervous system, increase the risk of reflux and aspiration, increase intracranial pressure and intraocular pressure, and endanger patients with cerebral aneurysms and ocular trauma. Therefore, at the moment of advocating comfortable anesthesia medical services, sufentanil-induced cough response is a problem that clinical anesthesiologists need to focus on and urgently solve. It has been reported that ketamine can reduce the incidence of cough caused by opioids. Esketamine is a pure dextro-enantiomer of ketamine and an NMDA antagonist with potent analgesic and bronchodilator effects. In this study, Dixon sequential method was used to study the median effective dose ( ED50 ) of intravenous esketamine pretreatment to prevent sufentanil-induced cough, and to explore the effect of age on ED50. To provide reference for clinical rational selection of esketamine dose.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EsketamineDrug
The initial dose of esketamine was set as 0.06 mg / kg, and the injection time of esketamine was 5 s. One minute after injection of esketamine, sufentanil 0.4 μg / kg was injected within 5 s, and the number of coughs within 1 min after injection was recorded. According to the evaluation of sufentanil-induced cough, the dose of esketamine was adjusted. If the patient had no cough ( negative reaction ), the dose of esketamine in the next patient was reduced until the cough reaction occurred. If the patient had a cough reaction ( positive reaction ), the dose of esketamine in the next patient was increased until the cough disappeared. The dose ratio of adjacent esketamine was 1.1. Each group was selected from the previous patient with positive reaction until the 7 groups of positive and negative reactions appeared alternately, and the test was completed.
