What this study is about

The aim of this study is to observe the effect of adjustable headrests on ventilation function in overweight and obese patients through clinical experiments, and to explore the impact on the incidence of hypoxemia during painless curettage in overweight and obese patients. Participants will be randomly allocated to three groups: the supine head-straight position group(Group A), the supine head-lateral position group(Group B), and the adjustable headrest group(Group C). These three groups of patients underwent painless curettage surgery in the daytime operating room and the occurrence of hypoxemia will be observed.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Treatments and study arms

the supine head-lateral position group

Other

the supine head-lateral position group: during the perioperative period, keep the patient's head tilted to the left or right

the adjustable headrest group

Other

the adjustable headrest group: placing an adjustable pillows on the patient's head to align the patient's external auditory canal horizontally with the sternum

the supine head-straight position group

Other

the supine head-straight position group: during the perioperative period, keep the patient's head upright

Primary outcomes

Incidence of hypoxemia1,2 and 3 minutes after anesthesia induction

Incidence of hypoxemia will be recorded after anesthesia induction

Respiratory rate and oxygen saturationThe time of entering the daytime operating room, intraoperative period., 1 minute after the patient wakes up

Respiratory rate and oxygen saturation will be recorded at 4 time points, including the time of entering the daytime operating room(Time 0), 1 minute after anesthesia induction(Time 1), 2 minute after anesthesia induction(Time 2), 3 minute after anesthesia induction(Time 3), 1 minute after the patient wakes up(Time 4)
