Resuscitation

Out-of-hospital cardiac arrest (OHCA) is common among females and males alike; however, previous studies reported differences in outcomes between sexes in different regions. To investigate possible explanations for this disparity, we examined sex differences in resuscitation interventions in the province of British Columbia (BC). ⋯ We did not detect an association between sex and bystander CPR or chest compression rate. In those who did not achieve prehospital ROSC, males had 1.2-fold greater odds of being transported to hospital compared to females.

Observational Study
Improvement of Consciousness before Initiating Targeted Temperature Management.
Following cardiac arrest, return of spontaneous circulation (ROSC) in patients may be followed by spontaneous neurological recovery, which may decrease the potential adverse effects of treatments in post-cardiac arrest care, including those of Targeted Temperature Management (TTM). We investigated the percentage of post-arrest patients who experienced spontaneous neurological recovery, and the characteristics and neurological outcomes of these patients. ⋯ A significant portion of patients had spontaneous neurological recovery to GCS M6 within 3 h post ROSC, and had a favorable neurological outcome. Close monitoring of GCS and later initiation of TTM should be considered in those patients with a substantial likelihood of neurological recovery.

Prior studies have shown that hospital case volume is not associated with survival in patients with out-of-hospital cardiac arrest (OHCA). However, how case volume impact on survival for in-hospital cardiac arrest (IHCA) is unknown. ⋯ Unlike OHCA, low CPR volume is an indicator of good performing hospitals and increasing CPR case volume does not translate to improve survival for IHCA.
