The Regional Cerebral Oxygen Saturation Effect of Inotropes/Vasopressors Administered to Treat Intraoperative Hypotension: A Bayesian Network Meta-analysis.

J Neurosurg Anesthesiol 2021 Jun 10. Epub 2021 Jun 10.

Department of Anesthesiology, Perioperative and Pain Medicine, Stanford University School of Medicine, Stanford, CA Department of Anesthesiology, MMIMSR, MM (DU), Mullana, Haryana, India Bernard Becker Medical Library Department of Anesthesiology, Perioperative and Pain Medicine, Washington University in St. Louis School of Medicine, St. Louis, MO.

One of the main concerns of intraoperative hypotension is adequacy of cerebral perfusion, as cerebral blood flow decreases passively when mean arterial pressure falls below the lower limit of cerebral autoregulation. Treatment of intraoperative hypotension includes administration of drugs, such as inotropes and vasopressors, which have different pharmacological effects on cerebral hemodynamics; there is no consensus on the preferred drug to use. We performed a network meta-analysis (NMA) to pool and analyze data comparing the effect on cerebral oxygen saturation (ScO2) measured by cerebral oximetry of various inotropes/vasopressors used to treat intraoperative hypotension.

Obstructive sleep apnea prediction from electrocardiogram scalograms and spectrograms using convolutional neural networks.

Physiol Meas 2021 Jun 11. Epub 2021 Jun 11.

Biomedical Engineering, TOBB Ekonomi ve Teknoloji Universitesi, Sogutozu Cad. No:43, Cankaya, 06560, TURKEY.

Radiosurgery as a microsurgical adjunct: outcomes after microsurgical resection of intracranial arteriovenous malformations previously treated with stereotactic radiosurgery.

J Neurosurg 2021 Jun 11:1-12. Epub 2021 Jun 11.

1Department of Neurosurgery and Stanford Stroke Center, Stanford University Medical Center, Stanford.

Objective: Microsurgical resection of arteriovenous malformations (AVMs) can be aided by staged treatment consisting of stereotactic radiosurgery followed by resection in a delayed fashion. This approach is particularly useful for high Spetzler-Martin (SM) grade lesions because radiosurgery can reduce flow through the AVM, downgrade the SM rating, and induce histopathological changes that additively render the AVM more manageable for resection. The authors present their 28-year experience in managing AVMs with adjunctive radiosurgery followed by resection. Read More
