Study of Adjustable Headrests in Painless Curettage Surgery for Overweight and Obese Women Aged 20 to 50

What this Trial Is About

This trial investigates how adjustable headrests affect breathing function and the risk of low oxygen levels during painless curettage surgery in overweight and obese patients. It aims to understand the impact on breathing by comparing different head positions during the procedure. Participants are randomly assigned to one of three groups a supine head-straight position group where the head is kept upright, a supine head-lateral position group where the head is tilted left or right, and an adjustable headrest group where a pillow aligns the external ear canal horizontally with the sternum. All participants undergo painless curettage surgery in a daytime operating room. During the study, breathing rate, oxygen levels, heart rate, and blood pressure are monitored at specific times including before anesthesia, during surgery, and shortly after waking. The main focus is on measuring the incidence of low oxygen levels at 1, 2, and 3 minutes after anesthesia starts. Participants are observed closely throughout the procedure to assess ventilation outcomes and safety.
