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.

Comparative StudyThe cutaneous analgesic effect of class I antiarrhythmic drugs.
Local anesthetics, when applied to nerves, produce reversible loss of sensation by blocking Na+ channels. Because all Class I antiarrhythmic drugs are Na+ channel blockers, theoretically, they may have local anesthetic effects. In this study, we sought to define the cutaneous local anesthetic actions of three Class I antiarrhythmic drugs. ⋯ Three Class I antiarrhythmic drugs, quinidine (IA), mexiletine (IB), and flecainide (IC) have a local anesthetic effect on cutaneous analgesia.

Randomized Controlled TrialThe relative potencies for motor block after intrathecal ropivacaine, levobupivacaine, and bupivacaine.
In this study, we sought to determine the median effective dose (ED50) for motor block of intrathecal ropivacaine, levobupivacaine, and bupivacaine and to define their motor-blocking potency ratios. ⋯ There is a clinical profile of potency for motor block for the pipecolylxylidines when administered spinally: low, intermediate, and high for ropivacaine, levobupivacaine, and bupivacaine, respectively.

Multicenter Study Comparative StudyFive-year follow-up on the work force and finances of United States anesthesiology training programs: 2000 to 2005.
In the middle 1990s, there was a decrease in anesthesiology residency class sizes, which contributed to a nationwide shortage of anesthesiologists, resulting in a competitive market with increased salary demands. In 1999, a nationwide survey of the financial status of United States anesthesiology training programs was conducted. Follow-up surveys have been conducted each year thereafter. We present the results of the sixth survey in this series. ⋯ These results demonstrate the continuing need for institutional support to keep anesthesiology training departments financially stable.
