Improvement of the clinical skills of nurse anesthesia students using mini-clinical evaluation exercises in Iran: a randomized controlled study.

PURPOSE: The present study aimed to investigate the effect of a mini-clinical evaluation exercise (CEX) assessment on improving the clinical skills of nurse anesthesia students at Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran. METHODS: This study started on November 1, 2022, and ended on December 1, 2022. It was conducted among 50 nurse anesthesia students divided into intervention and control groups. The intervention group's clinical skills were evaluated 4 times using the mini-CEX method. In contrast, the same skills were evaluated in the control group based on the conventional method­that is, general supervision by the instructor during the internship and a summative evaluation based on a checklist at the end of the course. The intervention group students also filled out a questionnaire to measure their satisfaction with the miniCEX method. RESULTS: The mean score of the students in both the control and intervention groups increased significantly on the post-test (P<0.0001), but the improvement in the scores of the intervention group was significantly greater compared with the control group (P<0.0001). The overall mean score for satisfaction in the intervention group was 76.3 out of a maximum of 95. CONCLUSION: The findings of this study showed that using mini-CEX as a formative evaluation method to evaluate clinical skills had a significant effect on the improvement of nurse anesthesia students' clinical skills, and they had a very favorable opinion about this evaluation method.

Comparing the Effect of Clonidine and Dexmedetomidine on Intraoperative Bleeding in Spine Surgery.

BACKGROUND: Discopathy is one of the most common spinal surgeries. Hemodynamic control is important in bleeding reduction during the surgery. Clonidine and dexmedetomidine both are α2 agonists that help stabilize hemodynamics and prevent the increase of intraoperative bleeding. OBJECTIVES: In this study, the effects of clonidine and dexmedetomidine were compared in bleeding reduction during spinal surgery. METHODS: This randomized, double-blind clinical trial was conducted in 120 patients aged 20 to 50 years with ASA class I or II, undergoing spinal surgery. Patients were randomly divided into three groups. Group C received oral clonidine 0.2 mg, 90 minutes before entering the room. Group D received dexmedetomidine 0.5 µ/kg 15 minutes before anesthesia induction and 0.25 µ/kg/h infusion during operation. Group P received placebo as the control group. RESULTS: There was a significant reduction in intraoperative blood loss in patients who received clonidine (289 ± 130) and dexmedetomidine (344 ± 145) compared to the control group (462 ± 15) (P < 0.05), with a more dramatic reduction in the clonidine group (P < 0. 001).
