Randomized Controlled TrialPrevention of intravenous bacterial injection from health care provider hands: the importance of catheter design and handling.
Device-related bloodstream infections are associated with a significant increase in patient morbidity and mortality in multiple health care settings. Recently, intraoperative bacterial contamination of conventional open-lumen 3-way stopcock sets has been shown to be associated with increased patient mortality. Intraoperative use of disinfectable, needleless closed catheter devices (DNCCs) may reduce the risk of bacterial injection as compared to conventional open-lumen devices due to an intrinsic barrier to bacterial entry associated with valve design and/or the capacity for surface disinfection. However, the relative benefit of DNCC valve design (intrinsic barrier capacity) as compared to surface disinfection in attenuation of bacterial injection in the clinical environment is untested and entirely unknown. The primary aim of the current study was to investigate the relative efficacy of a novel disinfectable stopcock, the Ultraport zero, with and without disinfection in attenuating intraoperative injection of potential bacterial pathogens as compared to a conventional open-lumen stopcock intravascular device. The secondary aims were to identify risk factors for bacterial injection and to estimate the quantity of bacterial organisms injected during catheter handling. ⋯ The Ultraport zero stopcock with hub disinfection before injection was associated with a significant reduction in the risk of inadvertent bacterial injection as compared to the conventional open-lumen stopcock. Future studies should examine strategies designed to facilitate health care provider DNCC hub disinfection and proper device handling.

Randomized Controlled TrialTransthoracic echocardiography simulation is an efficient method to train anesthesiologists in basic transthoracic echocardiography skills.
The clinical utility of focused transthoracic echocardiography (TTE) is increasingly recognized in perioperative medicine. However its use is limited among anesthesiologists because of a lack of training. The most efficient training methods have not been determined. We hypothesized that simulation-based TTE training would be more effective than traditional lecture-based methods for teaching basic TTE skills to the anesthesiology residents. ⋯ This prospective randomized study demonstrated that anesthesiology residents trained with simulation acquired better skills in TTE image acquisition and anatomy identification on volunteer subjects. The educational benefit of simulation persisted even with introduction of hands-on instruction with volunteer subjects in both groups. The impact of these short-term educational approaches on longer-term retention and actual clinical application warrants further investigation.

Similar liability for trauma and nontrauma surgical anesthesia: a closed claims analysis.
Trauma care has many challenges, including the perception by nonanesthesia physicians of increased medical malpractice liability. We used the American Society of Anesthesiologists' Closed Claims Project database and the National Inpatient Sample (NIS) to compare the rate of claims for trauma anesthesia care to national trauma surgery data. We also used the American Society of Anesthesiologists' Closed Claims Project database to evaluate injury and liability profiles of trauma anesthesia malpractice claims compared to nontrauma surgical anesthesia claims. ⋯ Despite reported perceptions that trauma care involves a high risk of medical liability, there was no apparent increased risk of liability among inpatients presenting for trauma anesthesia care. The proportion in malpractice claims in trauma anesthesia care was not increased compared to nontraumatic surgical anesthesia care. With respect to medicolegal liability, these results support participation of anesthesia providers in multidisciplinary trauma care and organized systems.

Descriptive study of case scheduling and cancellations within 1 week of the day of surgery.
We performed a descriptive study of operating room (OR) case scheduling within 1 week of the day of surgery. ⋯ Planning anesthesia assignments, ORs to target, etc., can be done productively starting 2 working days ahead of surgery. There are so many changes to the OR schedule those last 2 workdays that anesthesia groups should be engaged with the scheduling office during that period. The primary predictor of additional net hours of cases to be scheduled is the difference between the allocated (i.e., forecasted) OR time and the hours scheduled so far.

Deficits in the provision of cardiopulmonary resuscitation during simulated obstetric crises: results from the Israeli Board of Anesthesiologists.
Cardiac arrest in the parturient is often fatal, but appropriate resuscitation in this special situation may save the lives of the mother and/or unborn baby. Concern has arisen as to application of recommended techniques for resuscitation in the obstetric patient. The Israel Board of Anesthesiology has incorporated simulation assessment into accreditation examinations. ⋯ Cricoid pressure during bag-mask ventilation was performed by 48% (25%) but described in debriefing by 80% of candidates (53%) (P = 0.08), and time setting for perimortem cesarean delivery was performed by 40% (29%) but described by 80% (53%) (P = 0.05) of examinees. CONCLUSIONS Senior anesthesiology residents have poor knowledge of resuscitation of the pregnant patient. The results suggest 2-stage simulation including an oral component may reveal disparities in knowledge not assessed by simulation alone, but definitive conclusions require further study.
