Akira Nishisaki is an attending intensivist at Children's Hospital of Philadelphia, with nearly two decades in pediatric airway management. Doug Atkinson, a pediatric cardiac anesthesiologist also from Boston Children's, joins him to discuss critical aspects of airway management in the pediatric ICU. They explore the alarming statistics of intubation failures and complications, advancements in techniques like video laryngoscopy, and the significance of effective teamwork. The conversation also emphasizes the role of training and checklists in improving patient safety during high-risk procedures.
Airway management in pediatric ICUs is highly risky, with first-pass intubation success rates averaging only 50% and significant adverse events possible.
The Near for Kids initiative enhances airway management by emphasizing patient-centered outcomes and teamwork in addressing both anticipated and unanticipated challenges.
Utilizing structured checklists improves communication and accountability among staff during airway management, ultimately fostering safer and more effective interventions.

High Risks of Airway Management in Pediatric ICU
Airway management in pediatric intensive care units (PICU) presents significant risks, making it the highest-risk time for patients. Studies report that first-pass success rates for airway intubation can be as low as 50%, with severe desaturation occurring in up to 20% of cases. Additionally, rates of cardiac arrest during the critical peri-intubation window vary between 2% to 15%, indicating that both anticipated and unanticipated difficulties can arise. The challenges are compounded by factors such as environmental conditions and the physiological differences of pediatric patients, highlighting the need for improved protocols and training.
The Importance of Training and Collaborative Efforts
Effective airway management requires a robust training system and collaborative efforts among healthcare professionals. The Near for Kids initiative aims to enhance airway management practices by expanding definitions of success, focusing not only on physical tube placement but also on patient-centered outcomes. This approach underscores the necessity of teamwork in anticipating and managing difficult airways reliably, integrating insights gained from previous cases to improve future performance. Consequently, this progressive perspective has significantly reduced adverse airway management events within the pediatric population.
Significance of Pre-Intubation Planning
Thorough pre-intubation planning plays a crucial role in managing difficult airways. Clinicians are advised to assess patient history for previous airway management issues and identify factors that might complicate intubation. An approach that includes a clear communication plan among team members ensures everyone is on the same page regarding anticipated challenges. This preparation may involve considering alternative airway devices and strategies, emphasizing the necessity of having specific tools ready before the procedure begins.
Evaluating Airway Devices and Techniques
The discussion emphasizes the growing role of advanced technologies such as video laryngoscopy in pediatric airway management. While traditional techniques remain relevant, the use of video laryngoscopy offers better visualization for trainees and professionals, thereby potentially improving first-pass success rates. However, it is crucial that medical staff are trained in both direct and video laryngoscopy techniques to ensure versatility in various clinical scenarios. The challenges presented by anatomical differences in smaller patients call for careful consideration of the tools used, ensuring that staff are equipped with the appropriate devices for different scenarios.
The Role of Checklists in Airway Management
Implementing structured checklists has proven beneficial in improving communication and accountability during airway management procedures. These checklists serve to enhance team coordination, ensuring each member understands their role and promoting timely call for assistance in emergencies. They help pre-emptively identify and address potential pitfalls, such as unavailable emergency equipment. Ultimately, adherence to checklists appears to promote safer and more effective airway management in high-pressure environments like the PICU.
Airway management remains the single highest risk time for our patients in pediatric ICU. Different studies of pediatric airway management report first pass success as low as 50%. Rates of severe desaturation as high as 20%, and significant rates of cardiac arrest ranging from two to 15% in the 30 minute peri intubation window alone. A difficult airway might be anticipated or unanticipated and is not just difficult endotracheal intubation, but also difficulties with mask ventilation. supraglottic airway devices, difficult rescue techniques including front of neck access and physiologically difficult airways, which we covered in previous episodes.
The good news is that the attention our community has been paying to these issues has reduced the rates of endo tracheal intubation (ETI) associated adverse events significantly, but there's still a long way to go. We are joined by Akira Nishisaki from NEAR 4 Kids & CHOP which has been one of the main drivers of improvements in this space for almost 20 years and who has an incredible knowledge of the literature and Doug Atkinson a pediatric anesthesiologist and cardiac intensivist from Boston Children's Hospital.
As always, we focus on how our expert panel do things in practice at their institutions whilst being aware of the evidence.
