    Sweet Dreams: Procedural Sedation in the PICU

    In this episode of PICU Doc on Call, hosts Dr. Monica Gray and Dr. Pradip Kamat explore procedural sedation in the pediatric ICU. They cover sedation levels, pre-screening, risk stratification using ASA classifications, and medication selection tailored to each patient's hemodynamic and respiratory status. Through real-world case discussions involving respiratory failure, septic shock, and acute neurological decline, they highlight the importance of end-tidal CO2 monitoring and early adverse event recognition. Key takeaways include avoiding the term "conscious sedation," preparing rescue plans, and prioritizing patient safety through careful assessment and monitoring. Show Highlights: Definitions and levels of sedation (minimal, moderate, deep sedation, and general anesthesia)Importance of terminology in procedural sedationMonitoring sedation levels using scales like the Richmond Agitation-Sedation Scale (RASS)Pre-screening and risk stratification considerations for pediatric patientsASA physical status classification system for assessing patient riskUnique challenges of procedural sedation in critically ill childrenAdverse events associated with pediatric procedural sedation, particularly respiratory complicationsManagement strategies for specific cases requiring sedation (e.g., respiratory failure, septic shock)Importance of end-tidal CO2 monitoring during sedationKey takeaways for safe sedation practices in the pediatric ICU setting References: Nir Atlas; Rahul C.

    Of Rats & Men: Approach to Coumadin Overdose in the PICU

    In this episode of PICU Doc on Call, hosts Dr. Monica Gray and Dr. Pradip Kamat discuss a 15-year-old girl who attempted suicide by ingesting rat poison, acetaminophen, ibuprofen, and amlodipine. The episode focuses on long-acting anticoagulant rodenticides (LAARs), such as brodifacoum, which inhibit vitamin K epoxide reductase, causing delayed coagulopathy. Key topics include clinical presentation, diagnostic evaluation, and management, emphasizing vitamin K1 as the primary antidote and prothrombin complex concentrate or fresh-frozen plasma for major bleeding. The patient stabilized with aggressive supportive care, including vasoactive agents and NAC therapy, alongside psychiatric intervention. Listen to learn more!

    Mind Your Scope: Bronchoscopy Pearls for the Pediatric Intensivist

    In this episode of PICU Doc on Call, Dr. Monica Gray and Dr. Pradip Kamat chat about flexible fiberoptic bronchoscopy (FFB) in the pediatric ICU. They walk through a case involving an eight-year-old who’s dealing with respiratory failure after a stem cell transplant. Along the way, they talk about when and why you might use bronchoscopy both for diagnosis and treatment—plus how to approach sedation and what effects the procedure can have on the heart and lungs. They also dive into important topics like managing hypoxia, handling increased airway and pulmonary vascular resistance, and what to keep in mind if your patient has a traumatic brain injury. The episode wraps up with tips for managing fever after the procedure and a quick look at how rigid bronchoscopy compares.

    Isoflurane in the PICU

    In this episode of "PICU Doc on Call," Drs. Monica Gray and Pradip Kamat from Children's Healthcare of Atlanta dive into the use of inhaled anesthetics, especially isoflurane, in the pediatric ICU. We’re focusing on those tough cases: refractory status asthmaticus and status epilepticus. We’ll chat about why isoflurane is our go-to over other agents like sevoflurane, desflurane, or nitrous oxide, and break down its bronchodilatory and anticonvulsant properties. We’ll also touch on important pharmacology concepts, such as MAC and the blood-gas partition coefficient, and discuss how we approach dosing and ventilator management when using isoflurane. Of course, we’ll also discuss the potential adverse effects that can come with prolonged use, and why it’s important to stop other sedatives and beta-agonists once you start isoflurane. Join us as we walk through the practical aspects and pearls for using inhaled anesthetics in the PICU! Show Highlights: Use of inhaled anesthetics in pediatric intensive care units (PICU)Focus on isoflurane for managing refractory status asthmaticus and status epilepticusComparison of inhaled anesthetic agents: isoflurane, sevoflurane, nitrous oxide, and desfluraneImportance of minimum alveolar concentration (MAC) and blood-gas partition coefficient in anesthetic pharmacodynamicsMechanism of action of isoflurane in airway management and bronchodilationClinical administration techniques for isoflurane in critically ill childrenVentilator management principles for intubated children with status asthmaticusRole of isoflurane in refractory and super-refractory status epilepticusPotential adverse effects and considerations for prolonged isoflurane useSummary of pharmacologic concepts essential for safe isoflurane therapy in pediatric patients References: Rogers Text Book of Pediatric Intensive Care: Chapter 47: Acute Severe Asthma.

    The Tylenol Trouble & the NAC comeback: Navigating Acetaminophen Toxicity in the PICU

    In this episode of *PICU Doc on Call*, Drs. Monica Gray, Pradip Kamat, and Rahul Damania chat about a 17-year-old girl who ended up with acute liver failure after she intentionally took 22.5 grams of acetaminophen. She came in 48 hours later with really high transaminases and an INR of 5.5, so she was admitted to the PICU. The hosts break down how acetaminophen affects the body, walk through its four clinical stages, and discuss how to manage it—focusing on N-acetylcysteine as the primary antidote. They also touch on other treatments, like fomepizole. Thankfully, this patient recovered without needing a liver transplant, which really shows how important it is to have a team approach with intensivists, hepatologists, toxicologists, and psychiatry all working together. Show Highlights: Clinical case presentation of a 17-year-old girl with acetaminophen ingestion leading to acute liver failureMechanism of acetaminophen toxicity and its metabolic pathwaysEpidemiology of acetaminophen toxicity in pediatric populationsPathophysiology of acetaminophen overdose and its effects on liver functionClinical manifestations and progression of acetaminophen toxicity through various stagesEvaluation and diagnostic criteria for assessing acetaminophen toxicityManagement strategies for acetaminophen overdose, including the use of N-acetylcysteine (NAC).Discussion of adjunctive therapies such as fomepizole in severe cases.Importance of supportive care in managing complications of acute liver failureAn interdisciplinary approach to treatment involving various medical specialties References: Fuhrman & Zimmerman - Textbook of Pediatric Critical Care Chapter ***.

    Mean Arterial Pressure in the PICU

    In this special “PICU Doc On Call Shorts” episode, pediatric ICU physicians Dr. Monica Gray, Dr. Pradip Kamat, and Dr. Rahul Damania break down the concept of Mean Arterial Pressure (MAP). Using a case of a six-year-old in septic shock, they discuss how to calculate MAP, normal pediatric values, and the physiological determinants and clinical significance of MAP. The hosts highlight MAP’s role in guiding management of critically ill children, review autonomic and endothelial regulation, and reinforce learning with a board-style question. This episode emphasizes practical bedside application for pediatric interns and ICU providers. Show Highlights: Overview of Mean Arterial Pressure (MAP) and its clinical significance in pediatric critical care.Introduction of a clinical case involving a 6-year-old child in septic shock.Explanation of the formula for calculating MAP and its application to the clinical case.Discussion of normal reference values for MAP in children and their clinical implications.Physiological determinants of MAP, including cardiac output and systemic vascular resistance.Role of the autonomic nervous system in regulating MAP through baroreceptor reflexes.Importance of maintaining adequate MAP for organ perfusion, particularly in critically ill patients.Clinical applications of MAP monitoring and management strategies in the PICU.Summary of key takeaways regarding MAP calculation, physiological determinants, and clinical relevance.Mention of related topics, such as invasive versus non-invasive blood pressure monitoring.
