High Intraoperative Serum Lactate Level is Associated with Acute Kidney Injury after Brain Tumor Resection.
Postoperative acute kidney injury (AKI) is associated with poor clinical outcomes. Identification of risk factors for postoperative AKI is clinically important. Serum lactate can increase in situations of inadequate oxygen delivery and is widely used to assess a patient's clinical course. We investigated the association between intraoperative serum lactate levels and AKI after brain tumor resection. ⋯ High intraoperative serum lactate levels were associated with AKI after brain tumor resection.

Real-time 3D Transesophageal Echocardiography for the Placement of Ventriculoatrial Shunt: A Case Series and Technical Note.
Ventriculoatrial (VA) shunts are used to manage hydrocephalus and idiopathic intracranial hypertension when peritoneal drainage of cerebrospinal fluid is not feasible. The technique of distal catheter placement during VA shunt insertion is controversial, especially between fluoroscopy-guided and transesophageal echocardiography (TEE)-guided techniques. ⋯ The combined use of 2D ultrasound and 3D TEE allowed for faster procedure times and more precise distal catheter confirmation, contributing to a more streamlined surgical procedure. This small case series underscores the feasibility, efficiency, and safety of anesthesiologist-delivered combined 2D ultrasound and 3D TEE during VA shunt insertion. The use of 3D TEE allows repeated confirmation of distal catheter position and has potential to improve patient safety during rare but complex VA shunt insertion procedures.

Simulation in Anesthesia for Perioperative Neuroscience: Present and Future.
The brain's sensitivity to fluctuations in physiological parameters demands precise control of anesthesia during neurosurgery, which, combined with the complex nature of neurosurgical procedures and potential for adverse outcomes, makes neuroanesthesia challenging. Neuroanesthesiologists, as perioperative physicians, work closely with neurosurgeons, neurologists, neurointensivists, and neuroradiologists to provide care for patients with complex neurological diseases, often dealing with life-threatening conditions such as traumatic brain injuries, brain tumors, cerebral aneurysms, and spinal cord injuries. ⋯ Simulation models, including high-fidelity manikins, virtual reality, and computer-based simulations, can replicate physiological responses, anatomical structures, and complications associated with neurosurgical procedures. The use of high-fidelity simulation can act as a valuable complement to real-life clinical exposure and training in neuroanesthesia.
