Summary

Eligible patients undergoing hysteroscopy were randomly assigned in a 1:1 ratio to receive intravenous anesthesia with either propofol (2 mg/kg) or remifentanil (0.4 mg/kg).Continuous monitoring of pulse oximetry (SpO2), blood pressure (BP), heart rate (HR), expired gas partial pressure of carbon dioxide, integrated respiratory index (IPI), tidal volume (TV), respiratory rate (RR), and minute ventilation (MV) was performed.During induction, the MOAA/S score was assessed every 30 seconds. If the MOAA/S score remained \>1, a supplementary dose of 1/2 of the initial dose was injected within 10 seconds.If more than 5 supplementary doses were required within 15 minutes, it was considered that the painless hysteroscopy failed and propofol was used to enhance sedation.Continuous oxygen administration at a flow rate of 5 liters per minute was provided through nasal catheters until the patient was fully alert with a MOAA/S score of 5 and vital signs were stable.Observation indicators included: (1) the success rate of hysteroscopy;(2) induction time (MOAA/S ≤ 1 after the first dose);(3) full recovery time of consciousness;(4) operation duration;(5) number of additional anesthetics;(6) incidence of hypotension, hypoxemia, sinus bradycardia, delayed recovery, and injection pain;(7) respiratory parameters and minimum SpO2, IPI values before anesthesia, after induction, and after awakening.

Conditions

• Ciprofol
• Hysteroscopy

Interventions

Type	Name	Description
DRUG	Ciprofol group	All patients received 5 μ g of sufentanil 1 minute before intravenous infusion of ciprofol, followed by intravenous injection of ciprofol (0.4mg/kg). When the MOAA/S score is ≤ 1, vaginal disinfection begins. During the induction of sedation, the MOAA/S score is evaluated every 30 seconds. If the MOAA/S score remains above 1, a supplementary dose of 1/2 of the initial dose is injected within 10 seconds. During the maintenance phase, supplementary doses are given when there are signs of physical activity, eye opening, or speech. If more than 5 additional doses are required within 15 minutes, painless hysteroscopy is considered a failure, and propofol is immediately used to enhance sedation.
