Summary

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.

  • Narcotism

Interventions

PROCEDURE

Controlled analgesia/sedation

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

PROCEDURE

Intravenous combined anesthesia

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.
