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.

Observational StudyFactors Associated With Perioperative Hospital Acquired Pressure Injury in Patients Undergoing Spine Surgery in the Prone Position: A Prospective Observational Study.
Hospital acquired pressure injury (HAPI) is associated with poor clinical outcomes and high medical costs. Patients undergoing surgery in the prone position are particularly vulnerable to perioperative HAPI. This prospective observational study investigated the factors associated with HAPI in patients undergoing elective spine surgery in the prone position. ⋯ The incidence of perioperative HAPI was 24.7% in patients undergoing elective spine surgery in the prone position. Long duration of prone positioning and intraoperative acidosis were associated with increased development of perioperative HAPI.

Evaluating a Novel EEG-Based Index for Stroke Detection Under Anesthesia During Mechanical Thrombectomy.
The rapid identification of acute stroke (AS) during and after anesthesia might lead to early interventions and improved outcomes. We investigated a novel 2-channel electroencephalogram (EEG)-based marker for stroke detection-the lateral interconnection ratio (LIR)-in AS patients having endovascular thrombectomy (EVT) with general anesthesia (GA) or sedation. The LIR in 2 reference groups of patients without postoperative neurological complications was used for comparison. ⋯ We demonstrated the utility of using AS patients undergoing EVT as a platform for assessing a novel EEG marker for the identification of stroke during anesthesia. Further, large-scale studies in AS patients during EVT and in patients undergoing different surgeries and anesthesia are required to validate the LIR.
