Pain Clinical Trial - Effect of Low-dose Esketamine Combined With

Status Recruiting

Clinical Trial Summary

Purpose: 1. To determine the efficacy of low-dose esketamine in painless gastrointestinal endoscopy. 2. To determine the safety of low-dose esketamine in painless gastrointestinal endoscopy. 3. To provide a theoretical basis and new ideas for the application of esketamine as a new drug in perioperative period.

Clinical Trial Description

Keeping spontaneous breathing anesthesia can provide patients with comfortable diagnosis and treatment experience during gastrointestinal endoscopy, which is a vital prerequisite for the large-scale development of this operation as well as the early screening and treatment of gastrointestinal malignancies. Clinically, fentanyl combined with propofol is the most commonly used anesthesia regimen for the painless gastroscopy, however its high incidence of respiratory and circulatory depression will threaten the safety of patients. Instead, esketamine has a good action in anesthesia and analgesics, a slighter respiratory depression, as well as with a remarkable improvement in adverse effects than ketamine. What has already been proved is that low- dose of esketamine can remarkably reduce the dosage of propofol during endoscopic retrograde cholangiopancreatography; In our pilot study, we found that not only the incidence of respiratory depression was significantly lower than that of fentanyl during endoscopic polypectomy, but also the dosage of propofol was reduced at the same time,suggesting that esketamine may have a potential superiority in the painless gastrointestinal endoscopy.Our project plans to collect the patients who have received painless gastroscopy and polypectomy in the hospital, and use a target-controlled infusion (TCI) of propofol in combination with esketamine, by observing the total dose of propofol , the time of recovery and the length of hospital stay, the satisfaction of patients and endoscopists, drug side effects,adverse events of respiratory and circulatory system and other indicators ,to evaluate the efficacy and safety of this anesthetic scheme. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
