Cardiopulmonary resuscitation (CPR) in the delivery room (DR) after birth is rare. We hypothesized that factors related to maternal, delivery, infant and resuscitation event characteristics associated with outcomes could be identified. We also hypothesized there would be substantial variation from the Neonatal Resuscitation Program (NRP) algorithm. ⋯ In this cohort of infants receiving chest compressions following delivery, recognizable pre-birth risk factors as well as resuscitation interventions associated with increased and decreased odds of achieving ROSC were identified. Chest compressions were frequently initiated in the first minute of the event and often prior to endotracheal intubation. Further investigations should focus on methods to decrease time to critical resuscitation interventions, such as successful endotracheal intubation and administration of the first dose of adrenaline, in order to improve DR-CPR outcomes.

To explore if electrographic status epilepticus (ESE) after cardiac arrest causes additional secondary brain injury reflected by serum levels of two novel biomarkers of brain injury: neurofilament light chain (NfL) originating from neurons and glial fibrillary acidic protein (GFAP) from glial cells. ⋯ ESE after cardiac arrest is associated with higher levels of serum NfL which may suggest increased secondary neuronal injury compared to matched patients without ESE but similar initial brain injury. Associations with GFAP reflecting glial injury are less clear. The study design cannot exclude imperfect matching or other mechanisms of secondary brain injury contributing to the higher levels of biomarkers of brain injury seen in the patients with ESE.

Controlled sequential elevation of the head and thorax (CSE) during active compression decompression (ACD) cardiopulmonary resuscitation (CPR) with an impedance threshold device (ITD) has been shown to increase cerebral perfusion pressure and cerebral blood flow in previous animal studies as compared to the traditional supine position. The potential for this novel bundled treatment strategy to improve survival with intact neurological function is unknown. ⋯ The novel bundled resuscitation approach of CSE with ACD + ITD CPR increased favorable neurological survival versus C-CPR in a swine model of cardiac arrest.

To describe trends in pediatric in-hospital cardiac arrest drug administration and to assess temporal associations of the Pediatric Advanced Life Support (PALS) guideline changes with drug usage. ⋯ Changes to the PALS guidelines for lidocaine and bicarbonate were not temporally associated with acute changes in the use of these medications; however, better alignment with these updates was observed over time. A minor update to the language surrounding atropine in the PALS text was associated with a modest acute change in the observed use of atropine. Future studies exploring other factors that influence prescribers in pediatric IHCA are needed.

Observational Study
Lactate and hypotension as predictors of mortality after in-hospital cardiac arrest.
Guidance on post-cardiac arrest prognostication is largely based on data from out-of-hospital cardiac arrest (OHCA), despite clear differences between the OHCA and in-hospital cardiac arrest (IHCA) populations. Early prediction of mortality after IHCA would be useful to help make decisions about post-arrest care. We evaluated the ability of lactate and need for vasopressors after IHCA to predict hospital mortality. ⋯ Post-ROSC lactate and need for vasopressors may be helpful in stratifying mortality risk in patients requiring mechanical ventilation after IHCA.
