Atropine: re-evaluating its use during paediatric RSI

The Prehospital Emergency Anaesthetic in 2022

Prehospital emergency anesthesia (PHEA) is a commonly performed prehospital procedure with inherent risks. The processes and drug regimens behind PHEA are continually updated by prehospital teams across the country as part of their governance structure. Essex & Herts Air Ambulance has recently updated this practice by reviewing the entire process of performing PHEA. Through experiential learning in a high-volume service, audit, and a contemporary literature review, a new standard operating procedure has been developed to combat common problems, such as hypotension, associated with the more traditional methods of performing PHEA. The aim of this article was to summarize the literature behind this new standard operating procedure, systematically breaking down the core components of performing a PHEA and the rationale behind them. The key components identified in the review are indications for PHEA, airway assessment, peri-intubation oxygenation, preparation for PHEA, drug dosing, special circumstances, and failed intubation. One significant change is the drug dosage regimen; 1 μg/kg fentanyl, 2 mg/kg ketamine, and 2 mg/kg rocuronium is recommended as the main drug dosing regimen for both medical and trauma patients. Other changes include preoxygenation with a nasal cannula in addition to the nonrebreather mask, optimizing patients in the preparation phase by considering inopressors or fluid bolus and ensuring a "sterile cockpit" to control the surrounding environment to ensure the first intubation attempt is the best attempt.

Variation in Prehospital Protocols for Pediatric Respiratory Distress Management in the United States

OBJECTIVE

This study aimed to compare statewide emergency medical services protocols for the management of pediatric respiratory distress.

METHODS

We performed a descriptive study of emergency medical services protocols for the management of pediatric respiratory distress in the United States, excluding those without model or mandatory protocols. We compared medication recommendations for specific disease processes, including asthma, croup, epiglottitis, anaphylaxis, generalized respiratory distress, intubation, and drug assisted intubation.

RESULTS

Thirty-four state protocols were included. All had protocols to address the management of pediatric respiratory distress. There was high agreement in albuterol use for bronchospasm and epinephrine use in anaphylaxis. Epinephrine was recommended in all anaphylaxis protocols, 27 croup protocols (79%), and 3 epiglottitis protocols (9%). Six states (18%) called for albuterol in patients with generalized respiratory distress. Steroid recommendations and indications had variance among states; 26 states (76%) allowed steroid use in patients with asthma, 19 states (56%) recommended steroid use in anaphylaxis, and 11 (32%) recommended steroid use in croup protocols. The route for steroid administration also varied among protocols. Five states (15%) allowed continuous positive airway pressure application in pediatric patients, whereas endotracheal intubation and rapid sequence intubations had varying requirements as well as recommendations for use. Twelve (35%) listed impending or current respiratory failure as an indication, whereas other states had specific markers, such as Glasgow Coma Scale or oxygen saturation, as indications.

CONCLUSIONS

All included states had specific recommendations for the management of pediatric respiratory distress. There was consistency in recommendations for albuterol use for wheezing and epinephrine use for anaphylaxis. However, there was wide variability in other uses for epinephrine, steroid administration, continuous positive airway pressure use, and specific treatments for croup and epiglottitis. The findings of this study provide a base for important future evidence-based protocol developments and changes in prehospital pediatric respiratory distress treatment.

Pediatric critical care

Care of the ill and injured child requires knowledge of unique pediatric anatomic and physiologic differences. Subtleties in presentation and pathophysiologic differences impact management. This article discusses pediatric resuscitation, the presentation and management of common childhood illness, pediatric trauma, and common procedures required in the critically ill child.

Challenges and advances in intubation: airway evaluation and controversies with intubation

Management of the airway is the first priority in any patient. Dealing with a difficult airway can be a challenge, whether or not it involves facemask ventilation, an intermediate airway device, laryngoscopy and intubation, or a surgical airway. Various scales predict which patient is likely to have a difficult airway. The goal of rapid sequence intubation (RSI) is to eliminate or mitigate untoward reflex responses to intubation. Although controversy has arisen regarding the various steps in RSI, it remains an essential component of emergency medicine practice.
