Description

Pillow for patient with obesity to lie on back

Technical Field

Background

Obesity is widely prevalent worldwide, and weight loss metabolic surgery is a major way to treat moderately severe obesity and its complications, with a rapid trend in surgical volume in recent years. Because of the various complications of moderately severe obese patients, the risk of perioperative sudden death of patients with reduced weight metabolic surgery is high, and the risk of postoperative complications is high. Studies have demonstrated that obstructive sleep apnea is an independent predictor of poor outcome in patients with weight loss surgery. OSA is more elevated in obese patients because of the thicker neck circumference, localized adipose tissue accumulation, and the tendency to lower upper airway caliber and collapse of the upper airway. OSA is reported to have a high incidence of 70.1% -90% in patients with reduced weight metabolism surgery, with 50% being severe OSA patients. The research proves that the OSA is closely related to complications after the weight reduction operation, the mortality rate, the incidence rate of deep vein thrombosis after the operation and the ICU conversion rate can be obviously increased within 30 days after the operation, the hospitalization time is prolonged, and the OSA is also related to anesthesia intubation difficulty and the like.
