INTRODUCTION: To obtain the optimal anesthesia depth is not easy in cardiovascular surgery patients where the haemodynamic reserve is limited, due to reasons such as not being able to give the desired dose of anesthetic agent, or the change in the pharmacokinetics of the agent in the heart-lung machine. This study was planned to assess the contribution of bispectral index (BIS) monitoring in the depth of anesthesia. METHODS: The patients were divided into 2 groups, and BIS monitoring was used for each patient...

Cotton rats (Sigmodon hispidus) are widely used as animal models for infectious disease and immunological research. They emulate many aspects of human disease pathogenesis, and the introduction of cotton rat-specific immunological reagents, cell lines and sequencing of relevant genes have all helped to increase the popularity of this disease model. However, the use of cotton rats is problematic owing to their propensity for aggressive responses when handled, which can lead to escape, increased stress to the animals, and bites to staff...

BACKGROUND AND OBJECTIVE: The principal challenges in the field of anesthesia and intensive care consist of reducing both anesthetic risks and mortality rate. The ASA score plays an important role in patients' preanesthetic evaluation. In this paper, we propose a methodology to derive simple rules which classify patients in a category of the ASA scale on the basis of their medical characteristics. METHODS: This diagnosis system is based on MR-Sort, a multiple criteria decision analysis model...

A cross-sectional survey study on French practice in ultrasound-guided regional anesthesia was carried out. A questionnaire (demographic data, assessment of the likely benefits of ultrasonography, and its use in daily practice: blocks and hygiene) was emailed to all members of the French-speaking association of anesthesiologists involved in regional anesthesia. The questionnaire was filled out and returned by 634 experienced anesthesiologists. An ultrasound machine was available in 94% of cases. Ultrasound-guided regional anesthesia has become the gold standard technique for three-quarters of responders...

IMPORTANCE: The Syrian civil war has resulted in large-scale devastation of Syria's health infrastructure along with widespread injuries and death from trauma. The capacity of Syrian trauma hospitals is not well characterized. Data are needed to allocate resources for trauma care to the population remaining in Syria. OBJECTIVE: To identify the number of trauma hospitals operating in Syria and to delineate their capacities. DESIGN, SETTING, AND PARTICIPANTS: From February 1 to March 31, 2015, a nationwide survey of 94 trauma hospitals was conducted inside Syria, representing a coverage rate of 69% to 93% of reported hospitals in nongovernment controlled areas...

PURPOSE OF REVIEW: The use of intraoperative MRI technology during neurosurgery has become increasingly more common over the past several years. These surgical procedures require a specialized operating room designed to accommodate an MRI machine, as well as MRI-compatible anesthesia equipment and monitors. The MRI environment also poses unique risks and challenges to both patients and medical staff. RECENT FINDINGS: General anesthesia in the MRI operating room suite poses several challenges not routinely experienced in a conventional operating room suite, and anesthesia providers delivering care in these suites must complete specialized training and screening...

This study evaluated the ability of a portable oxygen concentrator (POC) to provide fresh gas to an anesthetic machine via an Ayre's T-piece or a Bain circuit. Fraction of inspired oxygen (FiO2) was compared at flows of 0.5 to 3.0 L/min. Measured FiO2 was 96% at flow rates ≥ 1 L/min. Mean battery life at 1.0, 2.0, and 3.0 L/min was 4.21 ± 0.45, 2.62 ± 0.37 and 1.5 ± 0.07 hours, respectively. The POC proved to be useful and effective during 2 power outages. The POC was sufficient to prevent rebreathing in 70% of dogs using a T-piece circuit and 20% of dogs with a Bain circuit...

BACKGROUND: Advancement from 1:1 to 1:2 (attending to resident) supervision at the beginning of a CA-1 (clinical anesthesia) year can serve as a model for transition to milestone-based curricula. Currently most programs have an individual mixture of training and advancement criteria formed at the discretion of educational leadership. We designed a questionnaire to evaluate degree of variability at programs nationally. METHODS: After obtaining IRB approval, an anonymous survey was sent via Survey Monkey to all Anesthesiology Residency Program Directors with a link for faculty members...

BACKGROUND: Lung ultrasound (LUS) is a well-established method that can exclude pneumothorax by demonstration of pleural sliding and the associated ultrasound artifacts. The positive diagnosis of pneumothorax is more difficult to obtain and relies on detection of the edge of a pneumothorax, called the "lung point." Yet, anesthesiologists are not widely taught these techniques, even though their patients are susceptible to pneumothorax either through trauma or as a result of central line placement or regional anesthesia techniques performed near the thorax...
