Randomized Controlled Trial
Randomized, double-blinded, placebo controlled study of neuroprotection with lidocaine in cardiac surgery.
Cognitive decline after cardiac surgery remains common and diminishes patients' quality of life. Based on experimental and clinical evidence, this study assessed the potential of intravenously administered lidocaine to reduce postoperative cognitive dysfunction after cardiac surgery using cardiopulmonary bypass. ⋯ Lidocaine administered during and after cardiac surgery does not reduce the high rate of postoperative cognitive dysfunction. Higher doses of lidocaine and diabetic status were independent predictors of cognitive decline. Protective effects of lower dose lidocaine in nondiabetic subjects need to be further evaluated.

Early hematoma growth is one of the main determinants of mortality in patients with intracranial hemorrhage (ICH). Transcranial duplex sonography (TDS) might represent a useful tool for the bedside monitoring of early ICH enlargement. We aimed to correlate ICH volumes measured by TDS and CT scan in patients with ICH evaluated <3 hours of symptom onset. ⋯ TDS showed an excellent correlation with CT in measuring the extent of bleeding in patients with hyperacute ICH. TDS may represent a reliable useful tool for monitoring ICH noninvasively at the patient's bedside.

Approximately 25% of ischemic stroke patients awaken with their deficits. The last-seen-normal time is defined as the time the patient went to sleep, which places these patients outside the window for thrombolysis. The purpose of this study was to describe our center's experience with off-label, compassionate thrombolysis for wake-up stroke (WUS) patients. ⋯ Thrombolysis may be safe in WUS patients. Our center's experience supports considering a prospective, randomized trial to assess the safety and outcome of thrombolysis for this specific patient population.

The Cincinnati Prehospital Stroke Scale (CPSS) is recommended for emergency medical services use in identifying patients with stroke. Data evaluating its performance in the field are limited. We assessed the impact of training and use of the CPSS on the accuracy of paramedics' stroke patient identification and on-scene time. ⋯ Paramedic training in the CPSS, or its use, had no impact on the accuracy of their identification of patients with stroke/TIA or on-scene time.
