Neurological outcomes associated with prehospital advanced airway management in patients with out-of-hospital cardiac arrest due to foreign body airway obstruction

Association Between Advanced Airway Management With Adrenaline Injection and Prognosis in Adult Patients With Asystole Asphyxia Out-of-hospital Cardiac Arrest

“…In previous reports, AAM for patients with asphyxia was associated with poor neurological outcomes. 24 , 25 Unlike in previous reports, we did not find that performing AAM for patients with asphyxia OHCA in asystole had an opposite effect on favorable neurologic prognosis. One possible reason for this difference could be the different inclusion criteria for the group of patients for whom AAM was not performed.…”

“…[14][15][16][17][18][19][20][21][22][23] In some previous reports on AAM for asphyxia OHCA analyzed using the Utstein registry data, AAM was associated with increased risks for poor neurological outcomes. [24][25][26] Otomune et al reported in their subgroup analyses that AAM with adrenaline injection for patients with asphyxia due to FBAO has no effect on neurological outcomes but can improve survival. 24 AAM and adrenaline injection can be performed by EMS only for patients with cardiac arrest under the instruction of a medical doctor according to a local protocol in Japan.…”

“… 24 – 26 Otomune et al reported in their subgroup analyses that AAM with adrenaline injection for patients with asphyxia due to FBAO has no effect on neurological outcomes but can improve survival. 24 AAM and adrenaline injection can be performed by EMS only for patients with cardiac arrest under the instruction of a medical doctor according to a local protocol in Japan. 27 Especially, the patient in whom the adrenaline injection was administered to was definitely determined to be in cardiac arrest at that time.…”

Characteristics and Outcomes of Emergency Transferred Patients with Foreign Body Airway Obstruction in Tokyo, Japan

“…Patients with FBAO who experienced cardiac arrest had extremely poor outcomes and their proportion of favorable neurological outcome was 1.4%-2.6%. 5,11,13,15,16 Analysis of the risk factors leading to OHCA in this study revealed that the OHCA group comprised significantly older patients and had a higher proportion of men compared with the non-OHCA group. Considering dental problems and dysphagia, FBAO occurs more frequently among the older adults.…”

Impact of different medical direction policies on prehospital advanced airway management for out-of hospital cardiac arrest patients: A retrospective cohort study

“… 28 Although the data cannot tell us the details of AAM, asphyxia-induced OHCA patients who had received prehospital AAM exhibited worse neurological outcomes than those who had not received AAM. 29 Of cautionary note, these findings could be influenced by resuscitation time bias. 30 Our data showed similar results, even after excluding patients who had been ventilated with BVM, given resuscitation time bias that OHCA patients who achieved “early” ROSC inevitably would not have received AAM.…”
