In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Marilyn N. Bulloch, PharmD, BCPS, FCCM, speaks with Olfa Hamzaoui, MD, PhD, professor of intensive care at Robert Debré Hospital in Reims, France, about her Peter Safar Honorary Lecture at the 2025 Critical Care Congress. The conversation centers on tissue perfusion, microcirculation, and shock, with a focus on bridging the gap between bench research and bedside practice.

Dr. Hamzaoui shares insights on current scientific understanding of microcirculation and shock, including research on tools to monitor microcirculation, such as handheld video microscopy. The discussion highlights the utility of capillary refill time as a simple, noninvasive tool for guiding resuscitation. Dr. Hamzaoui advocates for early and repeated echocardiographic assessment in shock management, including during de-resuscitation. She also discusses her 2023 article in Clinical Medicine, which proposed titrating norepinephrine to individualized targets.

This episode offers a compelling look at how emerging tools and research can refine shock management and promote precision care in critical illness.

In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Kyle B. Enfield, MD, FCCM, speaks with Sumeet Rai, PhD, FCICM, senior intensivist at Canberra Hospital, about his study, “Pawsitive Care: Canine-Assisted Intervention for Anxiety in ICU Patients and Family Members: A Single-Center, Single-Arm Study,” published in the May 2025 compendium of Critical Care Explorations.

Dr. Rai explains how positive anecdotal experiences of animal therapy in the ICU inspired his team to conduct this study. Guided by infection control protocols, they implemented a program allowing accredited therapy dogs to visit patients and families for 15- to 20-minute sessions. More than 60% of patients and more than 90% of family members had a clinically meaningful reduction in anxiety scores, and patients reported decreased pain. No adverse events were observed, demonstrating the feasibility and safety of this approach.

Dr. Rai addresses the study’s limitations, such as the impracticality of conducting a randomized trial, and highlights the need for research into staff well-being, which appeared to benefit from therapy dog visits. He also underscores the importance of a safety program, including infection control precautions.

This episode offers practical insights for implementing animal therapy programs in the ICU and invites listeners to consider new approaches to improving mental health and well-being for patients, families, and staff.

In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Elizabeth H. Mack, MD, MS, FCCM, speaks with Rebecca Mitting, MD, MRCPCH, consultant pediatric intensivist and clinical lead for the PICU at Imperial College Healthcare NHS Trust in London. They discuss Dr. Mitting’s article, “Sedation and Ventilator Weaning Bundle and Time to Extubation in Infants With Bronchiolitis: Secondary Analysis of the Sedation AND Weaning in Children (SANDWICH) Trial,” published in the April 2025 issue of Pediatric Critical Care Medicine.

The SANDWICH trial, conducted in the United Kingdom, evaluated a nurse-led intervention of sedation scoring, goal-based sedation weaning, and protocolized extubation readiness testing. While the original trial demonstrated only a modest reduction in ventilation duration, Dr. Mitting’s subgroup analysis of infants with bronchiolitis found a reduction of median time to successful extubation by approximately 16 to 17 hours.

Dr. Mitting highlights the importance of these findings during the winter season when bronchiolitis drives up PICU occupancy and strain. The critical trade-off between minimizing ventilator days and avoiding extubation failure is discussed, as well as implementation challenges after the COVID-19 pandemic, the importance of protocolized care under resource strain, and future directions for predictive models and personalized strategies to optimize extubation timing.

Listeners will gain practical insights into evidence-based approaches for improving outcomes in infants with bronchiolitis and the broader implications for PICU workflow and patient safety.
