Brief summary

Hypoxia is the most common adverse reaction during sedation outside the operating room.Exploring novel drug combinations to reduce the incidence of hypoxia during sedation in patients undergoing transvaginal oocyte retrieval procedures enhances patient safety and lowers perioperative adverse event rates. This multicenter, prospective, randomized, controlled clinical study will compare the hypoxia incidence rate of the remimazolam-alfentanil combination against the commonly used propofol-alfentanil combination.

Interventions

Administer 7 μg/kg of fentanyl first,then given remimazolam 0.2 mg/kg (1-minute bolus), followed by 1 mg/kg/h infusion.

DRUGpropofol-alfentanil

Administer 7 μg/kg of fentanyl first,then given propofol 2 mg/kg (1-minute bolus), followed by 6 mg/kg/h infusion.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of HypoxiaPatients will be followed for the duration of hospital stay, an expected average about 2 hoursSpO₂ between 75% and 89% with duration \<60 seconds

Secondary

MeasureTime frameDescription
Incidence of severe hypoxiaPatients will be followed for the duration of hospital stay, an expected average about 2 hoursSpO2 \< 75% or 75% ≤ SpO2 \< 90% for ≥60 s
Incidence of subclinical respiratory depressionPatients will be followed for the duration of hospital stay, an expected average about 2 hours90% ≤ SpO₂ \< 95%
Proportion of hypoxic correction measuresPatients will be followed for the duration of hospital stay, an expected average about 2 hoursCorrective measures for hypoxia should be implemented in the following sequence: increase oxygen flow rate, perform jaw thrust, administer positive pressure ventilation via a face mask, insert a nasopharyngeal airway while performing jaw thrust, and proceed to endotracheal intubation or mechanical ventilation with a laryngeal mask until SpO₂ reaches ≥95%.

Other

MeasureTime frameDescription
The incidence of other adverse eventsPatients will be followed for the duration of hospital stay, an expected average about 2 hoursOther adverse events recorded by tools proposed by the World Society of Intravenous Anesthesia International Sedation Task Force
