Official title
A Study on Application of Adjustable Headrest in Painless Curettage Surgery for Overweight and Obese Patients: a Randomized Controlled Trial
Overview
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.
Interventions
- Other 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 - Other 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 - Other the supine head-straight position group
the supine head-straight position group: during the perioperative period, keep the patient's head upright
Primary outcome measures
- Incidence of hypoxemia [Time frame: 1,2 and 3 minutes after anesthesia induction]
- Respiratory rate and oxygen saturation [Time frame: The time of entering the daytime operating room, intraoperative period., 1 minute after the patient wakes up]
Secondary outcome measures (1)
- Heart rate and blood pressure [Time frame: The time of entering the daytime operating room, intraoperative period, 1 minute after the patient wakes up]
