Early (≤24 h) systemic procalcitonin (PCT) levels are predictive for unfavorable neurological outcome in patients after out-of-hospital cardiac arrest (OHCA). Subarachnoid hemorrhage (SAH) due to aneurysm rupture might lead to a cerebral perfusion stop similar to OHCA. The current study analyzed the association of early PCT levels and outcome in patients after SAH. ⋯ Early PCT levels in patients with SAH might reflect the severity of the overall initial stress response. However, the predictive value is poor, especially compared to the reported predictive values in patients with OHCA. Early PCT levels might be of little use in predicting neurological outcome after SAH.

Daily weight (DW) and examination of fluid balances (FB) are commonly used in assessments of extracellular fluid (ECF) and circulating blood volume (BV). We hypothesized that a calculated total body exchangeable solute, the main determinant of the ECF, would have high agreement and correlation with actual BV. ⋯ Total body exchangeable solute appears to be a valid and reliable measure of BV and can be calculated using information readily available at the bedside. The value of having this information automatically calculated and available at the bedside should be explored.

The interval from presentation with systemic inflammatory response syndrome (SIRS) to the start of antibiotic administration affects mortality in patients with sepsis. However, patients with subarachnoid hemorrhage (SAH) often develop SIRS directly from their brain injury, making it a less useful indicator of infection. We therefore hypothesized that SIRS would not be a suitable trigger for antibiotics in this population. ⋯ In this cohort of patients with SAH, time from SIRS onset until antibiotic administration was not related to functional outcomes. Our results indicate that SIRS is nonspecific in patients with SAH, and support the safety of withholding antibiotics in those who lack additional evidence of infection or hemodynamic deterioration.

The intracerebral hemorrhage (ICH) score is a simple grading scale that can be used to stratify risk of 30 day mortality in ICH patients. A similar risk stratification scale for subarachnoid hemorrhage (SAH) is lacking. We sought to develop a risk stratification mortality score for SAH. ⋯ The SAH score allows a practical method of risk stratification of the in-hospital mortality. The in-hospital mortality increases with increasing SAH mortality score. Further investigation is warranted to validate these findings.

Data regarding use of prothrombin complex concentrate (PCC) for international normalization ratio (INR) reversal in warfarin-associated intracranial hemorrhage (wICH) is variable with regards to dosages, adjunctive agents, and product choice. In 2012, we implemented a fixed, weight-based [30 IU/kg] dosing protocol of 3-factor PCC (3PCC) utilizing a rapid infusion rate and no requirement for fresh frozen plasma (FFP) following factor product administration. We aimed to evaluate the impact of this protocol on immediate and delayed INR reversal in patients admitted with wICH in the absence of FFP co-administration. ⋯ Fixed, weight-based dosing of 3PCC without adjunctive FFP resulted in high rates of complete INR reversal without significant adverse events.
