A solid knowledge associated with lumbar drainage (LD)-related infections in spontaneous subarachnoid hemorrhage (SAH) patients is necessary and that would be useful in taking effective measures to cope with this complication. We aimed to describe incidence rates and risk factors associated with LD-related infections in SAH patients. ⋯ The patients with LD for more than 4 days or with puncture site leakage had more risk of infection. Infected patients were more likely to stay longer in the hospital. MRCNS were identified as the most frequent causal pathogens. And the use of antibiotics during LD did not appear to reduce the risk of infection.

Infections are a common medical complication in hemorrhagic stroke patients, with vancomycin commonly used as empiric therapy. The purpose of this study was to evaluate the pharmacokinetic parameters of vancomycin in hemorrhagic stroke patients. ⋯ Patients with hemorrhagic stroke exhibited pharmacokinetic alterations favoring increased elimination of vancomycin when compared to predicted pharmacokinetic parameters based on population data. This may result in underexposure to vancomycin, leading to treatment failure and other medical complications.

Hypoalbuminemia has been identified as a predictor of morbidity and mortality in critically ill patients. There is very little data on the significance and the prognostic value of hypoalbuminemia in patients with aneurysmal subarachnoid hemorrhage (aSAH). This study analyzed the impact of hypoalbuminemia on patient presentation, complications, and outcomes. ⋯ In patients with aSAH, early hypoalbuminemia is an independent predictor of hospital mortality but not disability at discharge.

Severe traumatic brain injury is associated with a multi-systemic response and changes in metabolic demand. Patients requiring intracranial pressure monitoring or cerebrospinal fluid diversion, often signifies a greater severity of injury. For this group, the association between RBC transfusion, transfusion thresholds, and clinical recovery is unknown. In this study, we studied the association between transfusion and clinical recovery for severe traumatic brain injury patients requiring external ventricular drain or intracranial pressure monitor placement. ⋯ From our studies, we demonstrate no significant clinical benefit associated with stratified transfusion goals; however, there was a decrease in length of hospitalization for patients with transfusion thresholds of Hgb ≥ 8 mg/dL. Larger, randomized controlled trials may be required to more accurately assess outcomes in this patient population. In patients admitted for primary severe traumatic brain injury, we demonstrate no significant clinical benefit associated with stratified transfusion goals; however, there was a noticeable decrease in length of hospitalization for patients with transfusion thresholds of Hgb ≥ 8 mg/dL. Larger, randomized controlled trials may be required to more accurately assess outcomes in this patient population.

Pneumothorax is an under-recognized complication of apnea testing performed as part of the neurological determination of death. It may result in hemodynamic instability or even cardiac arrest, compromising ability to declare brain death (BD) and viability of organs for transplantation. We report three cases of pneumothorax with apnea testing (PAT) and review the available literature of this phenomenon. ⋯ Development of PAT may adversely affect the process of BD determination and could limit the opportunity for organ donation. Each institution should have preventive measures in place.
