RATIONALE: A guideline that both evaluates current practice and provides recommendations to address sedation, pain, and delirium management with regard for neuromuscular blockade and withdrawal is not currently available. OBJECTIVE: To develop comprehensive clinical practice guidelines for critically ill infants and children, with specific attention to seven domains of care including pain, sedation/agitation, iatrogenic withdrawal, neuromuscular blockade, delirium, PICU environment, and early mobility. DESIGN: The Society of Critical Care Medicine Pediatric Pain, Agitation, Neuromuscular Blockade, and Delirium in critically ill pediatric patients with consideration of the PICU Environment and Early Mobility Guideline Taskforce was comprised of 29 national experts who collaborated from 2009 to 2021 via teleconference and/or e-mail at least monthly for planning, literature review, and guideline development, revision, and approval. The full taskforce gathered annually in-person during the Society of Critical Care Medicine Congress for progress reports and further strategizing with the final face-to-face meeting occurring in February 2020. Throughout this process, the Society of Critical Care Medicine standard operating procedures Manual for Guidelines development was adhered to. METHODS: Taskforce content experts separated into subgroups addressing pain/analgesia, sedation, tolerance/iatrogenic withdrawal, neuromuscular blockade, delirium, PICU environment (family presence and sleep hygiene), and early mobility. Subgroups created descriptive and actionable Population, Intervention, Comparison, and Outcome questions. An experienced medical information specialist developed search strategies to identify relevant literature between January 1990 and January 2020. Subgroups reviewed literature, determined quality of evidence, and formulated recommendations classified as “strong” with “we recommend” or “conditional” with “we suggest.” Good practice statements were used when indirect evidence supported benefit with no or minimal risk. Evidence gaps were noted. Initial recommendations were reviewed by each subgroup and revised as deemed necessary prior to being disseminated for voting by the full taskforce. Individuals who had an overt or potential conflict of interest abstained from relevant votes. Expert opinion alone was not used in substitution for a lack of evidence. RESULTS: The Pediatric Pain, Agitation, Neuromuscular Blockade, and Delirium in critically ill pediatric patients with consideration of the PICU Environment and Early Mobility taskforce issued 44 recommendations (14 strong and 30 conditional) and five good practice statements. CONCLUSIONS: The current guidelines represent a comprehensive list of practical clinical recommendations for the assessment, prevention, and management of key aspects for the comprehensive critical care of infants and children. Main areas of focus included 1) need for the routine monitoring of pain, agitation, withdrawal, and delirium using validated tools, 2) enhanced use of protocolized sedation and analgesia, and 3) recognition of the importance of nonpharmacologic interventions for enhancing patient comfort and comprehensive care provision.

The objective of this study was to describe the patterns of heliox use in critical care units of an academic medical center. The design was a prospective case series involving 7 critical care units of an academic medical center. All patients receiving heliox therapy over a 4-year period were studied, with prospective recording of patient demographics and the location, mode, indication for, and duration of heliox use. Use pattern comparisons based on anatomic location (upper vs lower airway) and age group (pediatric vs adult) were performed by α² analysis and unpaired Student t test. Eighty-nine patients, aged 17.4 ± 20.9 years, received heliox for 30.5 ± 44.6 hours on 92 occasions. Pediatric (≤ 18 years) applications accounted for 72.8% of heliox use. Use was greater in frequency and scope during the final 2 study years, particularly in adults. Applications were split between upper airway (47%) and lower airway (53%) disorders. Airway manipulation was required in more adults (7/16) than in children (3/27) with upper airway obstruction (P < .05). The use patterns mirrored current literature emphases on postextubation stridor and asthma. This is the first description of heliox use patterns in the tertiary care critical care environment. Heliox use may be as dependent on practitioner experience as on published data. As a benign and relatively inexpensive therapy, heliox use should continue to be attractive, although ongoing study regarding efficacy in a number of settings is indicated.

BACKGROUND:During conditions of poor perfusion, the accuracy of conventional extremity-based pulse oximeters may be limited. Limited evidence suggests that forehead perfusion may be better preserve...
