In the long run, surgical treatment proves to the most effective measure for the treatment of both morbid adipositas and concomitant morbidity. Patients undergoing bariatric surgical procedures are a challenge to the anaesthesiologist: Obesity-associated morbidity, the potentially difficult airway and intravenous accesses as well as the demand for effective pain and anti-emetic therapy. Interrestingly, only sparse and conflicting data exist about the perioperative anaesthesiological management of these patients. This study retrospectively reviewed the previous perioperative anaesthesiological management and appraised critically the situation in the follow-ing analysis. A potential for improvement should be identified and included into a new SOP via the PDCA cycle of the quality management system. ⋯ Bariatric patients are a high risk patient group. Present-day anaesthesiological practice as well as the profound implementation of a SOP could permit safe anaesthesia and a minimised risk for complications. Due to the high PONV rate, a routine perioperative PONV prophylaxis should be implemented.

Comparative Study Controlled Clinical Trial
[Effectiveness of nephroprotection by the selection of contrast media used during vascular interventions in patients with chronic renal failure?].
The increasing number of endovascular procedures made aware of a kidney disease induced by contrast media (CM). Contrast-induced nephropathy (= CIN) can develop in 0.6-44 % of the treated patients by angiography and / or endovascular intervention. The incidence in high-risk patients ranges from 50 to 70 %. In most cases CIN is inconspicuous and reversible. But pre-existing chronic kidney disease, diabetes mellitus, age and variable different risk factors (e. g., PAOD) can induce irreversible renal impairment. The purpose of the presented trial is to investigate incidence, predictors, and out-come of CIN in chronic renal failure patients using two different CM; one non-ionic isoosmolar -iodixanol and the other non-ionic low-osmolar iopromide. ⋯ According to cost-effectiveness a low-osmolar monomeric contrast medium (LOCM) is a sufficient selection, under careful renal function control.
