Identifying Relevant Topics for Inclusion in an Ethics Curriculum for Anesthesiology Trainees: A Survey of Practitioners in the Field.

Anesthesiology training programs are tasked with equipping trainees with the skills to become medically and ethically competent in the practice of anesthesia and to be prepared to obtain board certification, yet there is currently no standardized ethics curriculum within anesthesia training programs in the United States. To bridge this gap, and to provide a validated ethics curriculum to meet the aforementioned needs, in July 2021, a survey was sent to anesthesia scholars in the field of biomedical ethics to identify key areas that should be included in such an ethics curriculum. The responses were rated on a Likert scale and ranked. This paper identifies the top ten topics identified as high priority for inclusion in an anesthesiology training program and consequently deemed most relevant to meet the educational needs of graduates of an anesthesiology residency: (1) capacity to consent; (2) capacity to refuse elective versus lifesaving treatment; (3) application of surrogate decisionmaking; (4) approach to do not resuscitate (DNR) status in the operating room; (5) patient autonomy and advance directives; (6) navigating patient beliefs that may impair care; (7) "futility" in end-of-life care: when to withdraw life support; (8) disclosure of medical errors; (9) clinical criteria for "brain death" and consequences of this definition; and (10) the impaired anesthesiologist.

Usefulness of preoperative point-of-care ultrasound measurement of the lateral parapharyngeal wall to predict difficulty in mask ventilation.

Measurement of the lateral parapharyngeal wall has been shown to correlate with severity of obstructive sleep apnea, which is believed to increase risk of difficulty in mask ventilation (MV). This study aimed to assess the efficacy of using ultrasound to measure the lateral parapharyngeal wall thickness (LPWT) to predict the difficulty of MV. The LPWT was measured as the distance between the inferior border of the carotid artery and the lateral wall of the pharynx. Difficulty of MV was assessed according to an MV scale. A total of 92 patients were enrolled. Measurements of the LPWT ranged from 1.52 to 4.43 cm. There was a significant correlation between LPWT and difficulty of MV (P = 0.004). Every increase in 1 cm of LPWT was associated with an odds of increase in MV score of 3.17 (P < 0.05). With a cutoff of 3.5 cm, the area under the curve for LPWT was 0.67. The negative predictive value was 0.89, and the positive predictive value was 0.57. Use of point-of-care ultrasound to measure the LPWT shows promise in its ability to aid in airway management planning. Ultrasonic measurements of the LPWT have reasonable accuracy for predicting difficulty of MV.

Outcomes of CMS-mandated fluid administration among fluid-overloaded patients with sepsis: A systematic review and meta-analysis.

INTRODUCTION: The outcomes of large-volume IVF administration to septic shock patients with comorbid congestive heart failure (CHF) and/or end-stage renal disease (ESRD) are uncertain and widely debated in the existing literature. Despite this uncertainty, CMS continues to recommend that 30 ml/kg of an intravenous crystalloid solution be administered to patients in septic shock starting within 3 h of presentation. We performed a systematic review and meta-analysis to assess the relationship between adherence to this guideline and outcomes among patients whose underlying comorbidities present a risk of fluid overload. METHODS: Our search was conducted on PubMed and Scopus through November 5, 2021 to identify studies that evaluated clinical outcomes among septic patients with CHF/ESRD based on volume of fluid administered. The primary outcome measured was mortality at 30 days post-hospital discharge. Other outcomes included the rates of vasopressor requirements, invasive mechanical ventilation during hospitalization, as well as length of stay in the intensive care unit and/or hospital. We used random effects meta-analysis when two or more studies reported the same outcome. RESULTS: We included five studies in the final meta-analysis, which comprised 5804 patients, 5260 (91%) of whom received non-aggressive fluid resuscitation, as defined by the studies' authors. Random-effects meta-analysis for all-cause mortality showed that aggressive fluid resuscitation was associated with statistically non-significant increased odds of mortality (OR 1.42, 95% CI 0.88-2.3, P = 0.15, I2 = 35%). There was no statistical association between volume of IVF administration and other outcomes evaluated. CONCLUSION: Among septic shock patients with CHF and/or ESRD, administration of greater than or equal to 30 ml/kg IVF was associated with a non-significant increase in odds of mortality. All other outcomes measured were found to be non-significant, although there was a trend toward better outcomes among patients in the restricted-volume compared to the standard-volume IVF groups. Since this meta-analysis only included five observational studies, more studies are needed to guide an optimal volume and rate of fluid administration in this patient population.
