Feasibility and Acceptability of a Low-Tech Simulation Using Local Resources in a Rural Community Hospital.

Simulation is an effective tool to learn or refresh skills and knowledge, but numerous barriers prevent the routine use of simulation. The purpose of this project was to assess the feasibility and acceptability of the use of a low-tech simulation kit by the hospital's personnel for overcoming those barriers. A phenomenological qualitative approach using semistructured interviews was conducted with a convenience sample of 5 Certified Registered Nurse Anesthetists (CRNAs) and a student registered nurse anesthetist at a rural community hospital. Additionally, a CRNA served as the facilitator and was interviewed. After the data were independently analyzed by 2 individuals, 6 themes emerged. A low-tech simulation was acceptable, although the sense of stress was difficult to replicate. The facilitator found that simulation preparation and execution were easier and less work than expected. A low-tech simulation kit is a viable option for increasing the frequency of simulating anesthesia emergencies and overcoming the barriers that prevent the frequent use of simulation in the clinical setting. Psychological fidelity can be enhanced through innovative methods (flip book containing screenshots of an electrocardiographic monitor, video) to overcome the limitations of a low-tech simulation.

Accuracy of Capillary and Arterial Whole Blood Glucose Measurements Using a Glucose Meter in Patients under General Anesthesia in the Operating Room.

BACKGROUND: The aim of this study was to evaluate the use of a glucose meter with surgical patients under general anesthesia in the operating room. METHODS: Glucose measurements were performed intraoperatively on 368 paired capillary and arterial whole blood samples using a Nova StatStrip (Nova Biomedical, USA) glucose meter and compared with 368 reference arterial whole blood glucose measurements by blood gas analyzer in 196 patients. Primary outcomes were median bias (meter minus reference), percentage of glucose meter samples meeting accuracy criteria for subcutaneous insulin dosing as defined by Parkes error grid analysis for type 1 diabetes mellitus, and accuracy criteria for intravenous insulin infusion as defined by Clinical and Laboratory Standards Institute guidelines. Time under anesthesia, patient position, diabetes status, and other variables were studied to determine whether any affected glucose meter bias. RESULTS: Median bias (interquartile range) was -4 mg/dl (-9 to 0 mg/dl), which did not differ from median arterial meter bias of -5 mg/dl (-9 to -1 mg/dl; P = 0.32). All of the capillary and arterial glucose meter values met acceptability criteria for subcutaneous insulin dosing, whereas only 89% (327 of 368) of capillary and 93% (344 of 368) arterial glucose meter values met accuracy criteria for intravenous insulin infusion. Time, patient position, and diabetes status were not associated with meter bias. CONCLUSIONS: Capillary and arterial blood glucose measured using the glucose meter are acceptable for intraoperative subcutaneous insulin dosing. Whole blood glucose on the meter did not meet accuracy guidelines established specifically for more intensive (e.g., intravenous insulin) glycemic control in the acute care environment.

Tobacco intervention attitudes and practices among certified registered nurse anesthetists.

BACKGROUND: The period before surgery represents an opportunity for perioperative nurses, including certified registered nurse anesthetists (CRNAs), to address the tobacco use of their patients. OBJECTIVE: To assess the current practices and attitudes of CRNAs toward tobacco interventions. METHODS: A survey assessing current attitudes, practices and beliefs, and respondent demographics was mailed to 1,000 practicing CRNAs randomly selected from the membership of the American Association of Nurse Anesthetists, with one follow-up reminder. Summary statistics of survey responses were prepared. RESULTS: The response rate was 44% (N = 439). Almost all respondents (92%) reported routinely asking their patients if they smoke cigarettes, and the majority felt that it was their responsibility to advise their patients to quit smoking. However, most do not routinely do so. Identified barriers to intervention included a lack of time to intervene and a lack of training. Interest in learning more about tobacco interventions was high, with strong majorities willing to take an extra 5 minutes preoperatively to intervene and to refer patients to other intervention services. DISCUSSION: These results can inform efforts to promote tobacco use interventions in surgical patients by CRNAs. Increasing the frequency and effectiveness of tobacco use interventions provided by CRNAs would benefit not only immediate perioperative outcomes, but also the long-term health of surgical patients who take advantage of the surgical episode to initiate long-term tobacco abstinence.

Changing incidence, type, and natural history of conduction defects after coronary artery bypass grafting.

BACKGROUND: Cardiac conduction defects occur after cardiac surgery. We hypothesized that population aging and increased use of beta-blockers would increase the incidence of new conduction defects after coronary surgery. METHODS: We examined the medical records of 800 coronary artery bypass grafting (CABG) patients (400 from 1991 and 400 from 2001). Exclusion criteria included the following: preexisting conduction defect, permanent pacemaker, and perioperative atrial fibrillation, leaving 303 and 269 patients, respectively, included in the two study years. The incidence, type, and persistence of new conduction defects were determined from the preoperative, postoperative, and the predischarge electrocardiogram. Multivariate analysis identified predictors of new defects. RESULTS: Study populations were well-matched. There was a marked decrease in the incidence of new postoperative conduction defects from 1991 (19%) to 2001 (6%). There was also a change in the most frequently occurring block, from a right-bundle-branch-block in 1991 (10%) to first-degree atrioventricular block (3%) in 2001. Finally, conduction defects in 1991 were more transient. While 19% of 1991 patients showed a conduction defect early postoperatively, only 9% were persistent. In 2001, the incidence of conduction defects at discharge (7%), was equivalent to that early postoperatively (6%). Predictors of new conduction defects included year of operation, age, intraaortic balloon counterpulsation, number of vessels bypassed, and crystalloid cardioplegia. CONCLUSIONS: Our results were the opposite of those predicted. Our report identifies a changing incidence, type, and natural history of conduction defects after CABG. Our comparison demonstrated a decrease in the incidence of new conduction defects, as well as a qualitative change in the defects identified. Multivariate analysis provided predictors of new conduction defects after CABG.
