This study compares the automated anesthesia systems for painless abortion (AAS-PA) with traditional anesthesia in painless abortions. It assesses intraoperative indicators (hypoxemia, injection pain, hypotension, hemodynamics, respiratory depression) and postoperative outcomes (nausea, dizziness, recovery time, satisfaction). The AAS-PA group uses AI-adjusted intravenous ciprofol based on real-time vital signs and sedation depth; the traditional group relies on manual anesthesia. The goal is to verify if AAS-PA safely manages sedation, meets painless standards, reduces adverse events, and improves experience, aiding optimized automated protocols.

Parallel
AI Controlled General Anesthesia
Procedure/SurgeryDuring painless abortion, anesthesia will be induced using ciprofol, and controlled by an AI model.
General Anesthesia
Procedure/SurgeryAnesthesia will be induced using ciprofol, and controlled by experienced anesthesiologists.
Incidence of Hypoxemia
Hypoxemia is defined as blood oxygen saturation below 92% at any time.
Area under curve of hypoxemia
The area where SpO2 is below 92%.
Duration of colonoscopy
Lowest value of blood oxygen saturation
Induction and maintenance doses of anesthesia
Doses are recorded in mg/kg/h. The induction period is defined as the interval from the start of anesthesia to the first BIS value below 60. The maintenance period is defined as the interval from the first BIS value below 60 to the end of the drug infusion.
