High-flow nasal oxygen for children's airway surgery to reduce hypoxaemic events: a randomised controlled trial. THE LANCET. RESPIRATORY MEDICINE 2024; 12:535-543.

Abstract
BACKGROUND Tubeless upper airway surgery in children is a complex procedure in which surgeons and anaesthetists share the same operating field. These procedures are often interrupted for rescue oxygen therapy. The efficacy of nasal high-flow oxygen to decrease the frequency of rescue interruptions in children undergoing upper airway surgery is unknown. METHODS In this multicentre randomised trial conducted in five tertiary hospitals in Australia, children aged 0-16 years who required tubeless upper airway surgery were randomised (1:1) by a web-based randomisation tool to either nasal high-flow oxygen delivery or standard oxygen therapy (oxygen flows of up to 6 L/min). Randomisation was stratified by site and age (<1 year, 1-4 years, and 5-16 years). Subsequent tubeless upper airway surgery procedures in the same child could be included if there were more than 2 weeks between the procedures, and repeat surgical procedures meeting this condition were considered to be independent events. The oxygen therapy could not be masked, but the investigators remained blinded until outcome data were locked. The primary outcome was successful anaesthesia without interruption of the surgical procedure for rescue oxygenation. A rescue oxygenation event was defined as an interruption of the surgical procedure to deliver positive pressure ventilation using either bag mask technique, insertion of an endotracheal tube, or laryngeal mask to improve oxygenation. There were ten secondary outcomes, including the proportion of procedures with a hypoxaemic event (SpO2 <90%). Analyses were done on an intention-to-treat (ITT) basis. Safety was assessed in all enrolled participants. This trial is registered in the Australian New Zealand Clinical Trials Registry, ACTRN12618000949280, and is completed. FINDINGS From Sept 4, 2018, to April 12, 2021, 581 procedures in 487 children were randomly assigned to high-flow oxygen (297 procedures) or standard care (284 procedures); after exclusions, 528 procedures (267 assigned to high-flow oxygen and 261 assigned to standard care) in 483 children (293 male and 190 female) were included in the ITT analysis. The primary outcome of successful anaesthesia without interruption for tubeless airway surgery was achieved in 236 (88%) of 267 procedures on high-flow oxygen and in 229 (88%) of 261 procedures on standard care (adjusted risk ratio [RR] 1·02, 95% CI 0·96-1·08, p=0·82). There were 51 (19%) procedures with a hypoxaemic event in the high-flow oxygen group and 57 (22%) in the standard care group (RR 0·86, 95% CI 0·58-1·24). Of the other prespecified secondary outcomes, none showed a significant difference between groups. Adverse events of epistaxis, laryngospasm, bronchospasm, hypoxaemia, bradycardia, cardiac arrest, hypotension, or death were similar in both study groups. INTERPRETATION Nasal high-flow oxygen during tubeless upper airway surgery did not reduce the proportion of interruptions of the procedures for rescue oxygenation compared with standard care. There were no differences in adverse events between the intervention groups. These results suggest that both approaches, nasal high-flow or standard oxygen, are suitable alternatives to maintain oxygenation in children undergoing upper airway surgery.

Appraisal of Australian and New Zealand paediatric sepsis guidelines. Emerg Med Australas 2024; 36:436-442. [PMID: 38403429 DOI: 10.1111/1742-6723.14381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 01/04/2024] [Accepted: 02/05/2024] [Indexed: 02/27/2024]
Abstract
OBJECTIVE Clinical practice guidelines (CPGs) are an important tool for the management of children with sepsis. The quality, consistency and concordance of Australian and New Zealand (ANZ) childhood sepsis CPGs with the Australian Commission on Safety and Quality in Healthcare (ACSQHC) sepsis clinical care standards and international sepsis guidelines is unclear. METHODS We accessed childhood sepsis CPGs for all ANZ states and territories through Paediatric Research in Emergency Departments International Collaborative members. The guidelines were assessed for quality using the AGREE-II instrument. Consistency between CPG treatment recommendations was assessed, as was concordance with the ACSQHC sepsis clinical care standards and international sepsis guidelines. RESULTS Overall, eight CPGs were identified and assessed. CPGs used a narrative and pathway format, with those using both having the highest quality overall. CPG quality was highest for description of scope and clarity of presentation, and lowest for editorial independence. Consistency between guidelines for initial treatment recommendations was poor, with substantial variation in the choice and urgency of empiric antimicrobial administration; the choice, volume and urgency of fluid resuscitation; and the choice of first-line vasoactive agent. Most CPGs were concordant with time-critical components of the ACSQHC sepsis clinical care standard, although few addressed post-acute care. Concordance with international sepsis guidelines was poor. CONCLUSION Childhood sepsis CPGs in current use in ANZ are of variable quality and lack consistency with key treatment recommendations. CPGs are concordant with the ACSQHC care standard, but not with international sepsis guidelines. A bi-national sepsis CPG may reduce unnecessary variation in care.
