IntroductionSince data regarding new-onset atrial fibrillation (AF) in septic shock patients are scarce, the purpose of the present study was to evaluate the incidence and prognostic impact of new-onset AF in this patient group.MethodsWe prospectively studied all patients with new-onset AF and all patients suffering from septic shock in a non-cardiac surgical intensive care unit (ICU) during a 13 month period.ResultsDuring the study period, 687 patients were admitted to the ICU, of which 58 patients were excluded from further analysis due to pre-existing chronic or intermittent AF. In 49 out of the remaining 629 patients (7.8%) new-onset AF occurred and 50 out of the 629 patients suffered from septic shock. 23 out of the 50 patients with septic shock (46%) developed new-onset AF. There was a steady, significant increase in C-reactive protein (CRP) levels before onset of AF in septic shock patients. ICU mortality in septic shock patients with new-onset AF was 10/23 (44%) compared with 6/27 (22%) in septic shock patients with maintained sinus rhythm (SR) (P = 0.14). During a 2-year follow-up there was a trend towards an increased mortality in septic shock patients with new-onset AF, but the difference did not reach statistical significance (P = 0.075). The median length of ICU stay among surviving patients was longer in patients with new-onset AF compared to those with maintained SR (30 versus 17 days, P = 0.017). The success rate to restore SR was 86%. Failure to restore SR was associated with increased ICU mortality (71.4% versus 21.4%, P = 0.015).ConclusionsAF is a common complication in septic shock patients and is associated with an increased length of ICU stay among surviving patients. The increase in CRP levels before onset of AF may support the hypothesis that systemic inflammation is an important trigger for AF.
We evaluated an optimized patient care program for patients undergoing lung resections in a prospective randomized pilot study. Using this fast track clinical pathway the rate of pulmonary complications could be significantly decreased as compared to a conservative treatment regimen; our results support the implementation of an optimized perioperative treatment in lung surgery in order to reduce pulmonary complications after major lung surgery.
An optimized patient care program in open infrarenal aortic aneurysm repair shows favorable results concerning need for postoperative assisted mechanical ventilation, time to full enteral feeding, and incidence of medical complications. Further ranomized multicentric trials are necessary to justify broad implementation (clinical trials. gov identifier NCT 00615888).
In patients undergoing lung surgery, single intercostal nerve block plus i.v. patient-controlled analgesia with morphine is not as effective as patient-controlled EDA with respect to pain control and restoration of pulmonary function.
We introduced and evaluated an optimized patient care program for patients undergoing open infrarenal aortic aneurysm repair which showed a significant advantage for "fast-track" patients in terms of postoperative morbidity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
