Intravenous nicardipine infusion is effective for rapid blood pressure control. However, its use requires hemodynamic monitoring in the intensive care unit (ICU) and is associated with high hospital cost. This study aimed to examine the effect of early versus late initiation of oral antihypertensives on ICU length of stay (LOS) and cost of hospitalization in patients with hypertensive intracerebral hemorrhage (ICH). ⋯ Early initiation of oral antihypertensives is safe and may have a significant financial impact on patients with hypertensive ICH.

The hyperoxidative state in traumatic brain injury (TBI) could produce oxidative damage on the ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Oxidative damage to nucleic acids in TBI patients has been studied, and higher concentrations of 8-OHdG were found in postmortem brain samples of subjects who died following TBI than in subjects who died from sudden cardiac death. Thus, the objective of this study was to determine whether there is an association between serum DNA and RNA oxidative damage and mortality in TBI patients. ⋯ To our knowledge, our study is the largest series reporting data on DNA oxidative damage in TBI patients and is the first reporting DNA and RNA oxidative damage in TBI patients associating lipid peroxidation and mortality.

Observational Study
Nitric Oxide-Based Treatment of Poor-Grade Patients After Severe Aneurysmal Subarachnoid Hemorrhage.
Patients with aneurysmal subarachnoid hemorrhage (aSAH) require close treatment in neuro intensive care units (NICUs). The treatments available to counteract secondary deterioration and delayed ischemic events remain restricted; moreover, available neuro-monitoring of comatose patients is undependable. In comatose patients, clinical signs are hidden, and timing interventions to prevent the evolution of a perfusion disorder in response to fixed ischemic brain damage remain a challenge for NICU teams. Consequently, comatose patients often suffer secondary brain infarctions. The outcomes for long-term intubated patients w/wo pupil dilatation are the worst, with only 10% surviving. We previously added two nitroxide (NO) donors to the standard treatment: continuous intravenous administration of Molsidomine in patients with mild-to-moderate aSAH and, if required as a supplement, intraventricular boluses of sodium nitroprusside (SNP) in high-risk patients to overcome the so-called NO-sink effect, which leads to vasospasm and perfusion disorders. NO boluses were guided by clinical status and promptly reversed recurrent episodes of delayed ischemic neurological deficit. In this study, we tried to translate this concept, the initiation of intraventricular NO application on top of continuous Molsidomine infusion, from awake to comatose patients who lack neurological-clinical monitoring but are primarily monitored using frequently applied transcranial Doppler (TCD). ⋯ Even in comatose/intubated patients, TCD-guided dual-compartment administration of NO donors probably could reverse macrospasm and seems to be feasible. The number of DCI was much lower than expected in this specific subgroup, indicating that this treatment possibly provides a positive impact on outcomes. A randomized trial should verify or falsify our results.

Medical simulation for the teaching of procedural skills to health-care providers is an effective method of instruction to improve safety, quality, and procedural efficiency. There are several commercially available simulators for lumbar puncture training; however, there is currently no model available for lumbar drain intrathecal catheter placement. ⋯ A high-fidelity lumbar drain simulator can be constructed in a cost-effective manner. We have detailed the materials and assembly of our successful design in order to provide a novel educational tool for procedural instruction and practice.
