Observational Study
Effect of vertical location on survival outcomes for out-of-hospital cardiac arrest in Singapore.
A large proportion of out-of-hospital cardiac arrest (OHCA) cases occur in high-rise residential buildings. This study aims to investigate the effect of vertical location on survival outcomes and response times. ⋯ Vertical location is associated with OHCA survival probability with a U-shaped response, and this significance remained after adjustment for other significant OHCA variables. This relationship is likely multifactorial and more research is needed to elucidate the various factors.

Cerebral oximetry (rSO2) may be useful in assessing the probability of return of spontaneous circulation (ROSC). However, the potential of assessing the trend in the rSO2 value has not been discussed when determining the probability of ROSC. ⋯ The combination of rSO2 (baseline) with the amount of maximum rise in rSO2 value over time might be a new index for the prediction of ROSC that could be useful in guiding cardiopulmonary resuscitation. Further studies are needed to validate these findings.

To evaluate communication issues during dispatcher-assisted cardiopulmonary resuscitation (DACPR) for paediatric out-of-hospital cardiac arrest in a structured manner to facilitate recommendations for training improvement. ⋯ This structured evaluation identified specific issues in paediatric DACPR communication. Our training recommendations focus on situation and language specific guideline application and moving beyond verbal communication by utilizing the smart phone's functions. Prospective efforts are necessary to follow-up its translation into better paediatric DACPR outcomes.

To assess the performance of neuroprognostic guidelines proposed by the American Academy of Neurology (AAN), European Resuscitation Council/European Society of Intensive Care Medicine (ERC/ESICM), and American Heart Association (AHA) in predicting outcomes of patients who remain unconscious after cardiac arrest. ⋯ Though each guideline had components that performed well, only the ERC/ESICM guideline yielded a 0% FPR. Amongst the AAN and AHA guidelines, false positives emerged more readily at 6 months, reflective of continuing recovery after discharge, even in a cohort inevitably biased by WLST. Further assessment of predictive modalities is needed to improve neuroprognostic accuracy.

Data pertaining to clinical characteristics and outcomes of cardiac arrest (CA) due to drug overdose (ODCA) are limited. We hypothesized that patients with ODCA would have binary outcomes (brain death or functional recovery) compared to patients in whom CA was due to another etiology. ⋯ Despite similar neurological recovery and survival rates to hospital discharge, ODCA patients were more likely than non-ODCA patients to progress to brain death. Larger prospective studies analyzing ODCA are needed to better understand potential treatment options and prognostic tools in this cohort.
