Multicenter StudyAnesthesia-related cardiac arrest in children with heart disease: data from the Pediatric Perioperative Cardiac Arrest (POCA) registry.
From 1994 to 2005, the Pediatric Perioperative Cardiac Arrest Registry collected data on 373 anesthesia-related cardiac arrests (CAs) in children, 34% of whom had congenital or acquired heart disease (HD). ⋯ Children with HD were sicker compared with those without HD at the time of anesthesia-related CA and had a higher mortality after arrest. These arrests were reported most frequently from the general operating room and were likely to be from cardiovascular causes. The identification of causes of and factors relating to anesthesia-related CA suggests possible strategies for prevention.

Randomized Controlled Trial Multicenter StudyThe effect of bispectral index monitoring on long-term survival in the B-aware trial.
When anesthesia is titrated using bispectral index (BIS) monitoring, patients generally receive lower doses of hypnotic drugs. Intraoperative hypotension and organ toxicity might be avoided if lower doses of anesthetics are administered, but whether this translates into a reduction in serious morbidity or mortality remains controversial. The B-Aware Trial randomly allocated 2463 patients at high risk of awareness to BIS-guided anesthesia or routine care. We tested the hypothesis that the risks of death, myocardial infarction (MI), and stroke would be lower in patients allocated to BIS-guided management than in those allocated to routine care. ⋯ Monitoring with BIS and absence of BIS values <40 for >5 min were associated with improved survival and reduced morbidity in patients enrolled in the B-Aware Trial.

Multicenter StudyWhen blood is not an option: factors affecting survival after the use of a hemoglobin-based oxygen carrier in 54 patients with life-threatening anemia.
In consenting Jehovah's Witness patients and others for whom blood is contraindicated or not available, hemoglobin-based oxygen carrier (HBOC)-201 may enable survival in acutely anemic patients while underlying conditions are treated. ⋯ Earlier, compared with later, administration by inexperienced users of HBOC-201 to patients with anemia was associated with improved chances of survival of acutely bleeding and hemolyzing patients. Survival was more likely if the duration and magnitude of low hemoglobin was minimized before treatment with HBOC-201.

Randomized Controlled Trial Multicenter StudyPosttraumatic stress disorder in aware patients from the B-aware trial.
The long-term consequences of an awareness episode vary. Some patients do not have any long-term disability, whereas others develop psychological problems that may be severe and persistent. In this study, we compared the incidence of posttraumatic stress disorder (PTSD) in patients with and without confirmed awareness who were randomized in the B-Aware Trial. ⋯ PTSD was common and persistent in the confirmed awareness patients of the B-Aware Trial. Strategies to prevent awareness in patients under general anesthesia are justified.

Randomized Controlled Trial Multicenter Study Comparative StudySugammadex provides faster reversal of vecuronium-induced neuromuscular blockade compared with neostigmine: a multicenter, randomized, controlled trial.
Sugammadex, a specifically designed gamma-cyclodextrin, is a selective relaxant binding drug that rapidly reverses rocuronium-induced and, to a lesser extent, vecuronium-induced neuromuscular blockade. In this study, we compared the efficacy of sugammadex and neostigmine for the reversal of vecuronium-induced neuromuscular blockade in patients scheduled for elective surgery. ⋯ Sugammadex provided significantly faster reversal of vecuronium-induced neuromuscular blockade compared with neostigmine.
