Clinical Trial
Hypoxemia and hypoventilation syndrome improvement after laparoscopic bariatric surgery in patients with morbid obesity.
The objective of this study was to evaluate the relationship between oxygen partial pressure (pO(2)), awake oxymetric saturation (SpO(2)), body mass index (BMI), and percentage of excess weight loss (EWL) in extremely severe obesity (BMI >50 kg m(-2)) and hypoxemia, before and after laparoscopic Roux-en-Y gastric bypass. ⋯ In patients with extremely severe obesity, bariatric surgery may improve significantly both SpO(2) and spirometric parameters, and EWL represents the factor that impacted the results.
