A study testing Intravenous combined anesthesia in people with Narcotism, run by Handan First Hospital at 1 site in China.
Trial summary
Fiber colonoscopy, as a terminal examination method for lower gastrointestinal diseases, often brings varying degrees of pain, discomfort, tension, and anxiety to patients.

About this study
Official title: The Application of Propofol and Remifentanil Mixed Solution for Controlled Sedation and Analgesia in Fiber Colonoscopy
Fiber colonoscopy, as a terminal examination method for lower gastrointestinal diseases, often brings varying degrees of pain, discomfort, tension, and anxiety to patients. Therefore, currently in clinical practice, intravenous anesthesia is often chosen to reduce discomfort. At present, intravenous propofol and fentanyl are most widely used in clinical practice, but intravenous general anesthesia can lead to hemodynamic fluctuations and an increase in anesthesia related complications such as prolonged hospital stay after surgery. Propofol and remifentanil have the characteristics of fast onset, short duration of action, and rapid awakening. The purpose of this study is to observe the efficacy and adverse reactions of remifentanil combined with low-dose propofol in patient-controlled analgesia and sedation during colonoscopy, in order to explore the safety and effectiveness of this method.
Read the detailed description
Fibercolonoscopy, as a terminal examination method for lower digestive tract diseases, often brings different degrees of pain and discomfort, tension and anxiety to patients. Therefore, at present, intravenous anesthesia is often used in clinical practice to reduce discomfort, and intravenous propofol combined with fentanyl is the most widely used in clinical practice. But intravenous general anesthesia can lead to hemodynamic fluctuations and an increase in anesthesiation-related complications such as longer stays in the hospital after surgery. Complications related to sedation and analgesia have attracted increasing attention in recent years. Studies have shown that most of the adverse events in endoscopy are related to the sedation and analgesia drugs used. With the successful application of patient-controlled analgesia (PCA) in the field of postoperative analgesia, this technique has also been used in the sedation and analgesia of gastroenteroscopy in recent years. Propofol has the characteristics of quick action, short time of action and rapid recovery, so it is very suitable for the anesthesia and sedation of painless abortion and painless gastroenteroscopy. Remifentanil, as an opioid μ receptor agonist, is easily hydrolyzed rapidly by non-specific esterases in plasma and tissues due to the ester bond contained in its chemical structure. Therefore, it has unique pharmacokinetic characteristics such as rapid intravenous injection, small volume of distribution, rapid clearance after drug withdrawal, no accumulation, metabolism is not affected by liver and kidney function, and has been widely used in various surgeries in recent years, especially in the anesthesia of short surgeries.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Controlled analgesia/sedationProcedure or surgery
During the pre anesthesia assessment, explain in detail to the patient the usage of the self-control pump and confirm that each patient can master it. Firstly, connect the self-control analgesic pump with a loading dose of 3 ml. Then, continuously pump in a mixture of propofol and remifentanil at a speed of 0.1 ml/kg/h. After the loading dose is completed, the examination can begin. During the operation, press the self-control handle according to the patient's sensation. Each press can quickly push 1ml of the medication, with a locking time of 1 minute
Intravenous combined anesthesiaProcedure or surgery
Intravenous slow infusion of fentanyl 1 μ G/kg, midazolam 0.02mg/kg, slowly administer propofol 0.8-1mg/kg after 2 minutes (time greater than 60 seconds), and start the examination when the patient's consciousness disappears and they do not respond. During the surgery, propofol is interrupted to maintain the auditory evoked potential index (AAI) between 30-40.
| Study group | Role | What they receive |
|---|---|---|
| Controlled analgesia/sedation (PCAS) group | Experimental | Each group of patients is required to open the right upper limb venous access as a routine, take the left side lying position, and continuously inhale oxygen with a mask at a flow rate of 8L/min, while connecting various monitoring devices. During the pre anesthesia assessment, explain in detail to the patient the usage of the self-control pump and confirm that each patient can master it. Firstly, connect the self-control analgesic pump with a loading dose of 3 ml. Then, continuously pump in a mixture of propofol and remifentanil at a speed of 0.1 ml/kg/h. After the loading dose is completed, the examination can begin. During the operation, press the self-control handle according to the patient's sensation. Each press can quickly push 1ml of the medication, with a locking time of 1 minute. Receives: Procedure: Controlled analgesia/sedation |
| Intravenous combined anesthesia group | Active comparator | Each group of patients is required to open the right upper limb venous access as a routine, take the left side lying position, and continuously inhale oxygen with a mask at a flow rate of 8L/min, while connecting various monitoring devices. Intravenous slow infusion of fentanyl 1 μ G/kg, midazolam 0.02mg/kg, slowly administer propofol 0.8-1mg/kg after 2 minutes (time greater than 60 seconds), and start the examination when the patient's consciousness disappears and they do not respond. During the surgery, propofol is interrupted to maintain the auditory evoked potential index (AAI) between 30-40. Receives: Procedure: Intravenous combined anesthesia |
What is being measured
The primary outcome is the main question the study is designed to answer.
Auditory evoked potential
The auditory evoked potential (AEPI) is a reactive electrical activity of the brain generated by auditory stimuli, reflecting the entire electrical activity from the cochlea to the cerebral cortex.Before taking anesthesia, check Record the AEPI values at 5 time points before anesthesia, at the beginning of the examination, during endoscopy to the splenic curvature, ileocecal region, and at the end of the examination.
Measured: through study completion，an average of 2 hours
Secondary outcomes (1)
The time from after surgery to OAA/S score reached 5 and Aldrete score reached 9
Evaluation and score were performed every minute after operation The time from surgery to OAA/S score of 5 and Aldrete score of 9 were recorded
Measured: through study completion，an average of 2 hours
