Background: Neuraxial anesthesia is conventionally performed using a landmark-based technique. Preprocedural ultrasound is often used in challenging clinical scenarios to identify an ideal needle path. The procedure is then carried out by the operator recreating the ultrasound needle path from memory. We suggest that a needle guidance system using the Microsoft HoloLens mixed reality headset, which projects a hologram of the ideal needle path, can assist operators in replicating the correct needle angulation and result in fewer needle passes.
Objective: The objective of the study was to develop software for the mixed reality HoloLens headset, which could be used to augment the performance of neuraxial anesthesia, and establish its face validity in lumbar spine phantom models.
Methods: We developed an ultrasound transducer marker and software for the HoloLens, which registers the position and angulation of the ultrasound transducer during preprocedural scans. Once an image of a clear path from skin to the intrathecal space is acquired, a hologram of the ideal needle path is projected onto the user's visual field. The ultrasound probe is removed while the hologram remains in the correct spatial position to visualize the needle trajectory during the procedure as if conducting real-time ultrasound. User testing was performed using a lumbar spine phantom.
Results: Preliminary work demonstrates that novice (2 anesthesia residents) and experienced operators (5 attending anesthesiologists) can rapidly learn to use mixed reality holograms to perform neuraxial anesthesia on lumbar spine phantoms.
Conclusions: Our study shows promising results for performing neuraxial anesthesia in phantoms using the HoloLens. Although this may have wide-ranging implications for image-guided therapies, further study is required to quantify the accuracy and safety benefit of using holographic guidance.

Objectives: Postoperative complications after major surgery, especially in vascular procedures, are associated with a significant increase in costs and mortality. Postoperative pulmonary complications (PPCs) have a notable impact on morbidity and mortality. The primary aim of this present study was to evaluate the effects of spinal anesthesia compared with general anesthesia on the incidence of PPCs in patients undergoing lower extremity bypass surgery.

Introduction: Cancer complicates approximately 1 in 2000 pregnancies, with increasing incidence due to factors such as increased maternal age, obesity and advancements in antenatal testing. Anaesthetists play a crucial role in managing pregnant patients with cancer, both during delivery and in providing anaesthesia for oncological treatments. This review explores the challenges in anaesthetic management and specific considerations for common cancers encountered in pregnant patients.

The optimal anesthetic technique for category 2 and 3 cesarean deliveries remains debated, with concerns about impacts on decision-to-delivery interval (DDI) and perinatal outcomes. This study examined the influence of epidural, spinal, and general anesthesia on DDI, surgical and postoperative complications, and neonatal outcomes. : This prospective cohort study at a tertiary perinatology center enrolled parturient women undergoing category 2 and 3 cesarean deliveries.

Arachnoid cysts are fluid-filled cavities that are usually asymptomatic and do not require surgical intervention. However, there are concerns and limited literature on the safety of neuraxial procedure in obstetric patients with cranial arachnoid cysts. We describe the anesthetic management of a pregnant patient with a large arachnoid cyst with mass effect on the cerebellum who presented in labor.
