Overview
Brief Summary
Peri - operative ultrasonography was used to evaluate the effects of protective lung ventilation on the postoperative lungs of obese patients.The purpose of this study was to apply ultrasound lung ventilation area score to the monitoring of pulmonary complications in patients with postoperative obesity.To verify the reliability and practicability of perioperative lung ultrasound quantitative scoring.
Detailed Description
Ultrasound lung ventilation area score was applied to monitor the pulmonary complications of patients after obesity operation to verify the perioperative period. The reliability and practicability of quantitative lung ultrasound score to clarify the effect of protective lung ventilation under perioperative pulmonary ultrasound monitoring on obesity patients.To guide the management of mechanical ventilation under general anesthesia and the prevention and treatment of postoperative pulmonary complications

Outcomes
Primary Outcomes
Lung ultrasound scoring
Time Frame: in the morning of the first day
Four signs were used in lung ultrasound scoring Lung ultrasound score: N (0): pleural line and A line, less than 3 B lines; B1 (1 mark): More than 3 B line; B2 (2 points): Fuse line B; C (3 points): Signs of lung consolidation. The higher the score is, the worse the pulmonary ventilation status is. When scoring, the sign with the greatest severity is taken as the score value of the examination area. There are 12 examination areas in both lungs, so we have a LUS The score is between 0 and 36
Secondary Outcomes
- Mechanical ventilation parameter(entering the operating room, in the morning of the first day ,the second day , the third day after surgery)
- Results of arterial blood gas analysis(entering the operating room, in the morning of the first day ,the second day , the third day after surgery)
