The cement is an adhesive substance that helps the attachment of the tick to the host skin, while the saliva contains a rich mixture of antihemostatic, anti-inf...

Conclusions: After establishing an liquid chromatography with tandem mass spectrometry detection method for therapeutic drug monitoring of CAB, our analyses involving a single patient undergoing hemodialysis indicated that higher than expected doses of CAB were required to achieve reasonable plasma concentrations. Our study demonstrates the usefulness of therapeutic drug monitoring for the evaluation of “new” drugs in patients with renal impairment.

Aneurysmal subarachnoid hemorrhage (aSAH) often causes cardiopulmonary dysfunction. Therapeutic strategies can be guided by standard (invasive arterial/central venous pressure measurements, fluid balance assessment), and/or advanced (pulse index continuous cardiac output, pulse dye densitometry, pulmonary artery catheterization) hemodynamic monitoring. We conducted a systematic review and meta-analysis of the literature to determine whether standard compared with advanced hemodynamic monitoring can improve patient management and clinical outcomes after aSAH. A literature search was performed for articles published between ...

Human albumin has been used extensively for decades as a nonwhole blood plasma replacement fluid in the perioperative and critical care setting. Its potential advantages as a highly effective volume expander must be weighed, however, against its potential harm for patients in the context of various neurological states and for various neurosurgical interventions. This narrative review explores the physiological considerations of intravenous human albumin as a replacement fluid and examines the extant clinical evidence for and against its use within the various facets of modern neuroanesthesia and neurocritical care practice.

Deep brain stimulation (DBS) is an effective surgical treatment for patients with various neurological and psychiatric disorders. Clinical improvements rely on careful patient selection and accurate electrode placement. A common method for target localization is intraoperative microelectrode recording (MER). To facilitate MER, DBS surgery is traditionally performed under local or regional anesthesia. However, sedation or general anesthesia is sometimes needed for patients who are unable to tolerate the procedure fully awake because of severe motor symptoms, psychological distress, pain, or other forms of discomfort. The ef...

Conclusions: Women were underrepresented compared with men as first author of articles published in 3 dedicated neuroanesthesiology and neurocritical care journals over the last 5 years. Women had the lowest representation as authors of Original Research Articles.

Conclusions: Of opioid-naive geriatric patients who underwent surgery for DSD, 0.3% developed chronic, continuous opioid use. Preoperative opioid use was the strongest predictor of prolonged utilization, which may represent suboptimal use of nonopioid alternatives, pre-existing opioid use disorders, delayed referral for surgical evaluation, or over-prescription of opioids for noncancer pain.

Four editions of the Brain Trauma Foundation’s (BTF) evidence-based guidelines have been published to guide clinical management after severe traumatic brain injury (TBI) and increase TBI research. We reviewed the association between published clinical severe TBI research and BTF guideline year of publication and guideline chapter topics. Using PubMed, we searched for peer-reviewed articles on severe TBI research published between 1975 and 2019. The frequency and study design of publications on chapter topics included in all 4 BTF guideline editions was collected and the relationship with published TBI research examin...

Conclusions: Individuals without a previous contralateral endarterectomy and/or history of diabetes are at lower risk of hemodynamic instability. The addition of computed tomography angiographic variables does not improve this prediction. Future prospective, randomized work is required to improve our ability to identify and treat individuals at high risk of instability during carotid angioplasty and stenting.
