Obesity is a disease of increasing prevalence. There is minimal research on the safety of sedation for general endoscopic procedures among super obese patients (BMI ≥ 50). The aim of our study was to evaluate the safety of moderate sedation and endoscopic procedural outcomes for super obese patients in a case-control study.We completed an age and sex-matched case-control study comparing 132 super obese patients with 132 non-obese controls. We assessed intra-procedure adverse events, delayed adverse events, doses of sedation medication used, and procedure duration at a tertiary care setting.The mean BMI for the obese cohort was 55.6 compared with 22.5 for the controls (P 0.001). The mean intra-procedure fentanyl and midazolam dose was higher for the obese patients compared with the controls, fentanyl 180 mcg, midazolam 7.7 mg vs fentanyl 148 mcg, midazolam 6.4 mg, respectively (P 0.001). There was a significantly higher percentage of brief intra-procedure hypoxia (oxygen blood saturation 90%) for the obese patients compared with the controls, 5% vs 0% (P = 0.02). There was no difference in delayed adverse events with 2% of the cases and 2% of the controls having delayed adverse events (P = 1.0). Procedure completion rates were 100% for both cases and controls.General endoscopic procedures can be safely and effectively performed in super obese patients with moderate sedation. Brief intra-procedure hypoxia more commonly occurs in super obese patients, and higher medication doses are required. |
