Purpose: Limited data exist on advanced critical care echocardiography (CCE) training programs for intensivists. We sought to describe a longitudinal echocardiography program and investigate the effect of distributed conditional supervision vs predefined en-bloc supervision, as well as the effect of an optional echocardiography laboratory rotation, on learners' engagement., Methods: In this mixed methods study, we enrolled critical care fellows and faculty from five University of Toronto-affiliated intensive care units (ICU) between July 2015 and July 2018 in an advanced training program, comprising theoretical lectures and practical sessions. After the first year, the program was modified with changes to supervision model and inclusion of a rotation in the echo laboratory. We conducted semistructured interviews and investigated the effects of curricular changes on progress toward portfolio completion (150 transthoracic echocardiograms) using a Bayesian framework., Results: Sixty-five learners were enrolled and 18 were interviewed. Four (9%) learners completed the portfolio. Learners reported lack of time and supervision, and skill complexity as the main barriers to practicing independently. Conditional supervision was associated with a higher rate of submitting unsupervised echocardiograms than unconditional supervision (rate ratio, 1.11, 95% credible interval, 1.08 to 1.14). After rotation in the echocardiography laboratory, submission of unsupervised echocardiograms decreased., Conclusion: Trainees perceived lack of time and limited access to supervision as major barriers to course completion. Nevertheless, successful portfolio completion was related to factors other than protected time in the echocardiography laboratory or unconditional direct supervision in ICU. Further research is needed to better understand the factors promoting success of CCE training programs., (© 2022. Canadian Anesthesiologists' Society.)

Purpose: Residency programs need to understand the competencies developed by residents during an intensive care unit (ICU) rotation, so that curricula and assessments maximize residents' learning. The primary study objective was to evaluate the feasibility for training programs and acceptability by residents of conducting a multi-competency assessment during a four-week ICU rotation., Methods: We conducted a prospective, multicentre observational pilot study in three ICUs. During weeks 1 and 4 of an ICU rotation, we conducted repeated standardized assessments of non-critical care specialty residents' competencies in cognitive reasoning (script concordance test [SCT]), procedural skills (objective structured assessment of technical skills [OSATS]-global rating scale], and communication skills through a written test, two procedural simulations, and a simulated encounter with a "family member". The feasibility outcomes included program costs, the proportion of enrolled residents able to complete at least one three-station assessment during their four-week ICU rotation, and acceptability of the assessment for the trainees., Results: We enrolled 63 (69%) of 91 eligible residents, with 58 (92%) completing at least one assessment. The total cost to conduct 90 assessments was CAD 33,800. The majority of participants agreed that the assessment was fair and that it measured important clinical abilities. For the 32 residents who completed two assessments, the mean (standard deviation) cognitive reasoning and procedural skill scores increased between weeks 1 and 4 [SCT difference, 3.1 (6.5), P = 0.01; OSATS difference for bag-mask ventilation and central line insertion, 0.4 (0.5) and 0.6 (0.8), respectively; both P ≤ 0.001]. Nevertheless, the communication scores did not change significantly., Conclusions: A monthly multi-competency assessment for specialty residents rotating in the ICU is likely feasible for most programs with appropriate resources, and generally acceptable for residents. Specialty residents' cognitive reasoning and procedural skills may improve during a four-week ICU rotation, whereas communication skills may not.

Purpose: To determine whether or not intravenous nitroglycerin (IV NTG) can prevent a decrease in near-infrared spectroscopy (NIRS) values during cardiopulmonary bypass (CPB)., Methods: We conducted a randomized double-blinded study in a tertiary academic center including 30 patients with a Parsonnet score>or=15 scheduled for a high-risk cardiac surgery. The patients were randomized to receive either IV NTG (initial dose of 0.05 microg.kg(-1).min(-1), followed by 0.1 microg.kg(-1).min(-1)) or placebo after anesthetic induction until the end of CPB. The primary outcome was a decrease of 10% in NIRS values during CPB., Results: Despite the absence of between-group difference in the mean cerebral oxygen saturation during CPB, there was a significant decrease in NIRS values during CPB in the placebo group, whereas mean NIRS values were maintained in the IV NTG group (-16.7% vs 2.3% in the NTG, P=0.019). Major hemodynamic variables were similar at corresponding time periods in both groups, while patients in the IV NTG group had higher CK-MB values and experienced greater blood loss during the first 24 hr postoperatively., Conclusion: Intravenous nitroglycerin administration before and during CPB may prevent a decrease in NIRS values associated with CPB in high-risk cardiac surgery. Further studies are warranted to determine the efficacy and the risks associated with IV NTG infusion for this indication during CPB in high-risk patients.
