Comparative StudySupraventricular arrhythmias in intensive care unit patients: short and long-term consequences.
Supraventricular arrhythmias (SVA), including atrial fibrillation and flutter, are common in surgical and nonsurgical intensive care unit (ICU) patients. There is increased mortality among surgical ICU patients who develop new-onset atrial arrhythmias after noncardiac, non-thoracic surgery. We sought to determine the preadmission and intra-ICU factors associated with the development of new-onset SVA and mortality in these patients. ⋯ New-onset SVA occur frequently in ICU patients and are markers of extremely high in-hospital and 1-yr mortality.

We describe three cases of previously unreported failures of the Bag-Ventilator Switch in Aestiva/5 anesthesia machines (GE Healthcare/Datex-Ohmeda, Madison, WI). Each failure mode produced a large breathing-circuit leak. ⋯ These cases demonstrate that it is imperative to always be prepared to immediately use an alternate method for ventilation. Cases describing failure to ventilate due to sudden equipment malfunction underscore the need to always have functioning backup ventilation equipment available.

Comparative StudyThe validity of bispectral index values from a dislocated sensor: a comparison with values from a sensor located in the commercially recommended position.
The influence of sensor dislocation on bispectral index (BIS) values is not clear. We compared the BIS values obtained from dislocated sensors with those from the commercially recommended positions. ⋯ The results indicate that during induction of and emergence from general anesthesia, a dislocated BIS sensor may produce questionable BIS values.

Clinical TrialCo-injection of clonidine prolongs the anesthetic effect of lidocaine skin infiltration by a peripheral action.
The addition of clonidine to local anesthesia prolongs the local anesthetic action, but in humans, the contribution of a peripheral mechanism remains unclear. ⋯ Clonidine has a significant peripheral action in enhancing duration of local anesthesia on superficial co-infiltration with lidocaine.

Case ReportsCoagulopathy after cardiopulmonary bypass in Jehovah's Witness patients: management of two cases using fractionated components and factor VIIa.
Changes in the Jehovah's Witness (JW) blood refusal policy now give members the personal choice to accept certain processed fractions of blood, such as factor concentrates and cryoprecipitate. ⋯ Processed blood fractions can be a valuable adjuvant to drugs when treating bleeding in JW patients.
