Randomized Controlled Trial Comparative StudyThe Effects of Single-Dose Etomidate Versus Propofol on Cortisol Levels in Pediatric Patients Undergoing Urologic Surgery: A Randomized Controlled Trial.
The effects of general anesthetics on the hypothalamus-pituitary-adrenal axis and cortisol release in children are poorly characterized. Normal, daily fluctuation of cortisol levels complicates assessment of these effects. This study aimed to characterize the effects of etomidate compared with propofol on the normal cortisol secretory pattern in children undergoing urologic surgery by using a salivary cortisol assay. ⋯ Compared with propofol, a single induction dose of etomidate suppressed postoperative cortisol levels in healthy children undergoing urologic surgery. This suppression lasted approximately 24 hours and was not associated with any changes in clinical outcomes.

Caring for the Jehovah's Witness parturient is a complex task that presents a number of ethical, medical, and legal concerns because many Jehovah's Witnesses refuse allogeneic blood transfusion. Childbirth and its surrounding events may be associated with significant blood loss. Given their significant role in the intraoperative administration of blood products, anesthesia providers should be familiar with factors that must be considered in the perioperative care of Jehovah's Witness parturients. ⋯ Therefore, the patient-physician relationship must ensure that the individual patient's desires are accurately communicated, respected, and documented in the patient's medical record. The Perioperative Surgical Home model is appropriate for use in caring for Jehovah's Witness patients because it allows for the early and continuing coordination of care and communication between the patient and a multidisciplinary team. In this article, we present a focused review of concepts important to the provision of anesthetic care of parturients who are Jehovah's Witnesses and introduce an algorithmic perioperative approach that may be applied to the care of the Jehovah's Witness parturient undergoing an operative procedure.

Detection of Myocardial Dysfunction in Septic Shock: A Speckle-Tracking Echocardiography Study.
Patients with septic shock are at increased risk of myocardial dysfunction. However, the left ventricular ejection fraction (EF) typically remains preserved in septic shock. Strain measurement using speckle-tracking echocardiography may quantify abnormalities in myocardial function not detected by conventional echocardiography. To investigate whether septic shock results in greater strain changes than sepsis alone, we evaluated strain in patients with sepsis and septic shock. ⋯ In patients with septic shock, but not sepsis, myocardial strain imaging using speckle-tracking echocardiography identified myocardial dysfunction in the absence of changes in EF. These data suggest that strain imaging may play a role in cardiovascular assessment during septic shock.

The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative, clinical, and quality capture data from voluntarily participating anesthesia practices and health care facilities in the United States. ⋯ The database server of AQI, which houses the NACOR database, is protected by 2 firewalls within the American Society of Anesthesiologists' network infrastructure; this system has not been breached. The NACOR Participant User File, a deidentified case-level dataset of information from NACOR, is available to researchers at participating institutions. NACOR architecture and the nature of the Participant User File include both strengths and weaknesses.

ReviewAssociated Roles of Perioperative Medical Directors and Anesthesia: Hospital Agreements for Operating Room Management.
As reviewed previously, decision making can be made systematically shortly before the day of surgery based on reducing the hours of overutilized operating room (OR) time and tardiness of case starts (i.e., patient waiting). We subsequently considered in 2008 that such decision making depends on rational anesthesia-hospital agreements specifying anesthesia staffing. Since that prior study, there has been a substantial increase in understanding of the timing of decision making to reduce overutilized OR time. ⋯ The addition that we make in this article is to show that an agreement between an anesthesia group and a hospital can both reduce overutilized OR time and patient waiting: The anesthesia group and hospital will ensure, hourly, that, when there are case(s) waiting to start, the number of ORs in use for each service will be at least the number that maximizes the efficiency of use of OR time. Neither the anesthesia group nor the hospital will be expected to run more than that number of ORs without mutual agreement. Agreements assure that processes mutually beneficial to organizations, but not necessarily to individuals at each point in time, are performed as designed, especially in the setting of cognitive biases.
