Abstract

Introduction. The German guideline for sedation in gastrointestinal endoscopy was published in 2008. Several recommendations in this guideline, especially concerning staffing and structural requirements for sedation, have low evidence and therefore are subject to discussion in the field. Aim. Comparison of endoscopic complications in a department specialized for gastrointestinal and pulmological diseases before and after implementation of the German guideline grouped in sedation-associated and non-sedation-associated complications. Methods. Prospective documentation of complications with retrospective analysis of two patient groups (before guideline: 1.5.2008–30.4.2010; after guideline: 1.5.2010–30.4.2012) at which the sedation technique remained the same (balanced propofol sedation, BPS). Results. Both investigation periods covered almost 7000 procedures. Interventional and general complications were nonsignificantly elevated in the latter group (1.27% before vs. 1.55% after guideline, p = 0.08). Saturation decline (in both groups 0.26%) was unchanged, and circulation-associated complications (0.27% vs. 0.13%, p = 0.07) were reduced nonsignificantly. Necessity for the administration of flumazenil and for intensive care monitoring was reduced in a nonsignificant manner after the implementation of the guideline. Severe complications (reanimation, apnea, and death) were unchanged, and no patient with ASA I–II suffered from a severe complication. Propofol consumption was higher after guideline implementation. Conclusions. The recommendations of the new German sedation guideline do not significantly reduce complications in endoscopic procedures. Especially, procedures involving patients with ASA classes I and II do not require an additional staff member solely for sedation. Prospective randomized studies might be necessary to optimize the utilization of resources.
