Abstract
BACKGROUND

Gastroscopy and colonoscopy are important and common endoscopic methods for the diagnosis and treatment of gastrointestinal and colorectal diseases. However, endoscopy is usually associated with adverse reactions such as nervousness, nausea, vomiting, choking cough, and pain. Severe discomfort, such as vomiting, coughing, or body movement, may lead to aggravation of a pre-existing condition or even interruption of examination or treatment, especially in some critically ill patients with physiological dysfunction (e.g., cardiovascular or respiratory disease). The optimal methods for inducing analgesia and sedation in endoscopy are areas of ongoing debate; nevertheless, determining an appropriate regimen of sedation and analgesia is important.

AIM

To evaluate the effects of propofol combined with dezocine, sufentanil, or fentanyl in painless gastroscopy and colonoscopy.

METHODS

Four hundred patients were randomly assigned to one of four groups for anesthesia: intravenous dezocine, sufentanil, fentanyl, or saline. Propofol was administered intravenously for induction and maintenance of anesthesia.

RESULTS

The dosage of propofol in the dezocine group was significantly lower than those in other groups (P < 0.01). Bispectral index and Steward score (0-6 points, an unresponsive, immobile patient whose airway requires maintenance to a fully recovered patient) after eye opening in the dezocine group were significantly higher than those in other groups (P < 0.01). Awakening time and postoperative pain score (0-10 points, no pain to unbearable pain) in the dezocine group were significantly lower than those in other groups (P < 0.01). Mean arterial pressure and pulse oxygen saturation in the dezocine group were significantly more stable at various time points (before dosing, disappearance of eyelash reflex, and wakeup) than those in other groups (P < 0.01). The rates of hypopnea, jaw thrust, body movements, and usage of vasoactive drugs in the dezocine group were significantly lower than those in other groups (P < 0.01). Additionally, the rates of reflex coughing, nausea, and vomiting were not statistically different between the four groups (P > 0.05).

CONCLUSION

The combination of propofol and dezocine can decrease propofol dosage, reduce the risk for the development of inhibitory effects on the respiratory and cardiovascular systems, increase analgesic effect, decrease body movement, shorten awakening time, and improve awakening quality.

Keywords: Anesthesia, Dezocine, Propofol, Gastroscopy, Colonoscopy

Core tip: This study aimed to identify a comparatively satisfactory anesthetization regimen for painless gastroscopy and colonoscopy. The combination of propofol and dezocine can decrease propofol dosage, reduce the risk for the development of inhibitory effects on the cardiovascular and respiratory systems, increase analgesic effect, decrease body movement, shorten awakening time, and improve awakening quality. Anesthesia with propofol combined with dezocine is an adequate regimen of anesthesia and analgesia for gastroscopy and colonoscopy, which can increase the patient cooperation, quality and safety of the examination and treatment, and patient and physician satisfaction with anesthesia.
