Remimazolam Versus Propofol for Painless Abortion

Phase 2
Completed
Conditions
Anesthesia
Abortion Early
Interventions
Registration Number
NCT05635955
Lead Sponsor
Maternal and Child Health Hospital of Hubei Province
Brief Summary

The goal of this clinical trial is to compare the efficacy and safety of propofol vs. remimazolam in combine use of esketamine in women with early pregnancy undergoing painless abortion. The main questions it aims to answer are:

* whether remimazolam plus esketamine (R+E) has a better sedative and analgesic effectiveness than propofol plus esketamine (P+E).

* whether R+E has less adverse events than P+E.

Participants will be randomly allocated to two groups: R+E and P+E group.

* For those in group R+E: they will be administered with 0.3mg/kg remimazolam and 0.3mg/kg esketamine before the abortion surgery.

* For those in group P+E: they will be administered with 2mg/kg propofol and 0.3mg/kg esketamine before the abortion surgery.

We will compare R+E with P+E to see if the time to loss of conscious and time to recover from the sedation will be shorter and if there will be less severe adverse events in R+E.

Primary Outcome Measures
NameTimeMethod
Time to loss of consciousness5 - 30 minutes

The time from the study drug administration to loss of consciousness

Secondary Outcome Measures
NameTimeMethod
Success rate of sedationIntraoperative period, 30 minutes - 1.5 hours

Defined as completing the induction of anesthesia without an additional dosage

Recovery timePostoperative 30 minutes

Time to fully awake, defined as by a modified Aldrete score which will be recorded every 3 minutes from the end of the procedure with a recovery index (MAS) of 9 or more.

Mean arterial pressure (MAP)Intraoperative period, 30 minutes - 1.5 hours

MAP level will be monitored and recorded at 4 time points, including the entry into the operation room (Time 0), in sedation when vaginal dilator is placed (Time 1), in sedation when curettage begins (Time 2), and postoperative awakening (Time 3).

Heart rate (HR)Intraoperative period, 30 minutes - 1.5 hours

HR will be monitored and recorded at 4 time points, including the entry into the operation room (Time 0), in sedation when vaginal dilator is placed (Time 1), in sedation when curettage begins (Time 2), and postoperative awakening (Time 3).

Adverse eventsIntraoperative and post-operation, 30 minutes - 1.5 hours

The adverse events will be monitored and recorded during the operation and post-operation. AE will include: respiratory depression (defined as SpO2\< 95%), hypotension (defined as systolic arterial pressure \< 80 mmHg, or decreased baseline systolic blood pressure \> 20%), hypertension, bradycardia (defined as decrease in HR \< 50/min), number of body movements, injection site pain and nausea and vomiting.

Post-operative painPost-operation after fully awake, 30 minutes - 1 hour

It will be assessed by Visual Analogue Scale (VAS) pain score. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').
