A Study on Application of Adjustable Headrest in Painless Curettage Surgery for Overweight and Obese Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

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

Study summary

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.

Eligibility

Primary outcome measure(s)

• Incidence of hypoxemia — 1,2 and 3 minutes after anesthesia induction
  Incidence of hypoxemia will be recorded after anesthesia induction
• Respiratory rate and oxygen saturation — The 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)
