Abstract

Background: The present study investigates the postoperative oxygen dependence of morbidly obese patients after laparoscopic, gastric surgery. These patients are at risk to suffer from postoperative hypoxia because of their constitution and the type of surgery. Methods: Bariatric surgeries carried out at the Ludwig Maximilians University Hospital were retrospectively evaluated back to 2004 (OG;obese group). The control group consisted of non-obese patients who underwent gastric surgery (CG;control group). Patients who had received epidural anaesthesia, who were immediately transferred to an intensive care unit, or who underwent extensive gastric tumour surgery were excluded from the study. Oxygen requirements, the duration of oxygen delivery, the maximum oxygen flow rate, opioid re-quirements and oxygen saturation (preoperatively and during stay in the recovery unit) were evaluated using the anaesthesia documentation protocol. Results: 218 patients with a BMI >35 kg/m(2) and 77 with a BMI <35 kg/m(2) were included. There was no significant difference concerning oxygen requirements and the duration of oxygen administration (79.2% CG vs. 86.7% OG;p = 0.117). However, the groups displayed significant difference in the maximum oxygen flow delivered to the patients (4 litres/min. versus 6 litres/min.;p = 0.001). In the recovery room, oxygen saturation in the obese group was significantly lower compared to non-obese patients (91.0 +/- 3.7% CG versus 89.8 +/- 4.8% OG;p = 0.042). Conclusion: Morbidly obese patients un-dergoing laparoscopic gastric surgery need more oxygen and experience lower oxygen saturations than non-obese patients.
