Efficacy of parasternal peripheral nerve catheters no block for median sternotomy: a single-centre retrospective study.

Background: Sternal pain after cardiac surgery results in considerable discomfort. Single-injection parasternal fascial plane blocks have been shown to reduce pain scores and opioid consumption during the first 24 h after surgery, but the efficacy of continuous infusion has not been evaluated. This retrospective cohort study examined the effect of a continuous infusion of local anaesthetic through parasternal catheters on the integrated Pain Intensity and Opioid Consumption (PIOC) score up to 72 h.

Symptoms, Viral Loads, and Rebound Among COVID-19 Outpatients Treated With Nirmatrelvir/Ritonavir Compared With Propensity Score-Matched Untreated Individuals.

Background: Nirmatrelvir/ritonavir (N/R) reduces severe outcomes from coronavirus disease 2019 (COVID-19); however, rebound after treatment has been reported. We compared symptom and viral dynamics in individuals with COVID-19 who completed N/R treatment and similar untreated individuals.

Methods: We identified symptomatic participants who tested severe acute respiratory syndrome coronavirus 2-positive and were N/R eligible from a COVID-19 household transmission study.

Racial and Ethnic Disparities in Delivery In-Hospital Mortality or Maternal End-Organ Injury: A Multistate Analysis, 2007-2020.

In the United States, Black maternal mortality is 2-4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020.

Benzodiazepine-Free Cardiac Anesthesia for Reduction of Postoperative Delirium (B-Free): A Protocol for a Multi-centre Randomized Cluster Crossover Trial.

Delirium is common after cardiac surgery and is associated with adverse outcomes. Administration of benzodiazepines before and after cardiac surgery is associated with delirium; guidelines recommend minimizing their use. Benzodiazepine administration during cardiac surgery remains common because of its recognized benefits.

Pericarditis Management in Individuals Contemplating Pregnancy, Currently Pregnant, or Breastfeeding.

Purpose Of Review: Pericarditis complicates pregnancy planning, pregnancy, or the postpartum period, and the management approach requires special considerations. Here, we aim to summarize the latest research, diagnostic, and treatment strategies.

Recent Findings: Physiologic cardiovascular (CV) adaptations occurring during pregnancy complicate diagnosis, but for most patients, an electrocardiogram (ECG) and transthoracic echocardiogram (TTE) are sufficient to diagnosis pericarditis in the appropriate clinical context.

United States rural residence is associated with increased acute maternal end-organ injury or mortality after birth: a retrospective multi-state analysis, 2007-2018.

Background: Geographic-based healthcare determinants and choice of anesthesia have been shown to be associated with maternal morbidity and mortality. We explored whether differences in maternal outcomes based on maternal residence, and anesthesia type for cesarean and vaginal birth, exist.

Methods: This study was a retrospective multi-state analysis; patient residence was the predictor variable of interest and a composite binary measure of maternal end-organ injury or inpatient mortality was the primary outcome.

Baseline Intraoperative Left Ventricular Diastolic Function Is Associated with Postoperative Atrial Fibrillation after Cardiac Surgery.

Background: Detailed understanding of the association between intraoperative left atrial and left ventricular diastolic function and postoperative atrial fibrillation is lacking. In this post hoc analysis of the Posterior Left Pericardiotomy for the Prevention of Atrial Fibrillation after Cardiac Surgery (PALACS) trial, we aimed to evaluate the association of intraoperative left atrial and left ventricular diastolic function as assessed by transesophageal echocardiography (TEE) with postoperative atrial fibrillation.

Methods: PALACS patients with available intraoperative TEE data (n = 402 of 420; 95.

Benzodiazepines and postoperative delirium: should we be as cautious as we are?

A recent systematic review and meta-analysis by Wang and colleagues in the British Journal of Anaesthesia calls into question the concept that perioperative benzodiazepine administration is associated with development of postoperative delirium in older individuals after anaesthesia and surgery. This editorial focuses on potential bias within the systematic review and addresses major concerns surrounding benzodiazepine use in the older perioperative population.

Antiemetic Administration and Its Association with Race: A Retrospective Cohort Study.

Background: Anesthesiologists' contribution to perioperative healthcare disparities remains unclear because patient and surgeon preferences can influence care choices. Postoperative nausea and vomiting is a patient- centered outcome measure and a main driver of unplanned admissions. Antiemetic administration is under the sole domain of anesthesiologists.

Postoperative pericardial effusion, pericardiotomy, and atrial fibrillation: An explanatory analysis of the PALACS trial.

Background: In the Posterior left pericardiotomy for the prevention of atrial fibrillation after cardiac surgery (PALACS) trial, posterior pericardiotomy was associated with a significant reduction in postoperative atrial fibrillation (POAF) after cardiac surgery. We aimed to investigate the mechanisms underlying this effect.

Methods: We included PALACS patients with available echocardiographic data (n = 387/420, 92%).

Resident Physicians as Clinical Educators in Anesthesiology: A Narrative Review.

The importance of resident physicians as clinical educators is widely acknowledged in many clinical specialties and by national accreditation organizations for medical education. Within anesthesiology training programs, there is growing attention to the role of trainees as clinical educators. This narrative review describes the theoretical and demonstrated benefits of clinical teaching by residents in anesthesiology and other medical fields, summarizes current efforts to support and promote residents as educators, and suggests ways in which anesthesiology training programs can further assess and develop the role of residents as clinical educators.

Anesthesia and the neurobiology of fear and posttraumatic stress disorder.

Purpose Of Review: Dysfunction of fear memory systems underlie a cluster of clinically important and highly prevalent psychological morbidities seen in perioperative and critical care patients, most archetypally posttraumatic stress disorder (PTSD). Several sedative-hypnotics and analgesics are known to modulate fear systems, and it is theoretically plausible that clinical decisions of the anesthesiologist could impact psychological outcomes. This review aims to provide a focused synthesis of relevant literature from multiple fields of research.

Pregnancy Intention Screening in Patients With Systemic Rheumatic Diseases: Pilot Testing a Standardized Assessment Tool.

Objective: Systemic rheumatic conditions affect reproductive-aged patients and often require potentially teratogenic medications. We assessed the feasibility and impact of a standardized pregnancy intention screening question (One Key Question [OKQ]) in a large academic rheumatology practice.

Methods: This 6-month pilot quality improvement initiative prompted rheumatologists to ask female patients aged 18 to 49 years about their pregnancy intentions using OKQ.

Connected consciousness after tracheal intubation in young adults: an international multicentre cohort study.

Background: Connected consciousness, assessed by response to command, occurs in at least 5% of general anaesthetic procedures and perhaps more often in young people. Our primary objective was to establish the incidence of connected consciousness after tracheal intubation in young people aged 18-40 yr. The secondary objectives were to assess the nature of these responses, identify relevant risk factors, and determine their relationship to postoperative outcomes.
