Zenker's diverticulum is a common pathology in the transition zone of the posterior hypopharynx and esophagus. Surgical treatment is routinely performed by ENT and general surgeons. Besides the traditional open transcervical diverticulectomy, the introduction of transoral rigid treatment led to a paradigm change and is now the preferred treatment option for patients who are fit for general anesthesia. The implementation of interventional flexible endoscopy has opened another new micro-invasive approach for patients with high morbidity...

BACKGROUND: Glottic visualization can be difficult with cervical immobilization in patients with cervical spine injury. Indirect laryngoscopes may provide better glottic visualization in these groups of patients. Hence, we compared King Vision videolaryngoscope, C-MAC videolaryngoscope for endotracheal intubation in patients with proven/suspected cervical spine injury. METHODS: After standard induction of anesthesia, 135 patients were randomized into three groups: group C (conventional C-MAC videolaryngoscope), group K (King Vision videolaryngoscope), and group D (D blade C-MAC videolaryngoscope)...

OBJECTIVE Image guidance for spinal procedures is based on 3D-fluoroscopy or CT, which provide poor visualization of soft tissues, including the spinal cord. To overcome this limitation, the authors developed a method to register intraoperative MRI (iMRI) of the spine into a neuronavigation system, allowing excellent visualization of the spinal cord. This novel technique improved the accuracy in the deployment of laser interstitial thermal therapy probes for the treatment of metastatic spinal cord compression...

We report the application of ultrasound prescans for spinal anesthesia to morbid obesity patient. A 38-year-old woman with a body mass index (BMI) of 50 (weight: 110 kg; height: 148 cm) was scheduled to undergo pilonidal cyst resection at the bottom of the tailbone. Spinal anesthesia was selected for the procedure, because the patient's position during the surgery was prone and the patient had morbid obesity. To determine the spinal needle insertion point and the distance between the skin and dura, we planned to use ultrasound...

OBJECTIVE Medically refractory spasticity and dystonia are often alleviated with intrathecal baclofen (ITB) administration through an indwelling catheter inserted in the lumbar spine. In patients with cerebral palsy, however, there is a high incidence of concomitant neuromuscular scoliosis. ITB placement may be technically challenging in those who have severe spinal deformity or who have undergone prior instrumented thoracolumbar fusion. Although prior reports have described drilling through the lumbar fusion mass with a high-speed bur, as well as IT catheter implantation at the foramen magnum or cervical spine, these approaches have notable limitations...

The purple-spined sea urchin ( Arbacia punctulata ) is commonly found in shallow waters of the western Atlantic Ocean from the New England area of the United States to the Caribbean. Sea urchins play a major role in ocean ecology, echinoculture, and biomedical research. Additionally, sea urchins are commonly displayed in public aquaria. Baseline parameters were developed in unanesthetized urchins for righting reflex (time to regain oral recumbency) and spine response time to tactile stimulus. Tricaine methanesulfonate (MS-222) was used to sedate and anesthetize purple-spined sea urchins and assess sedation and anesthetic parameters, including adhesion to and release from a vertical surface, times to loss of response to tactile stimulus and recovery of righting reflex, and qualitative observations of induction of spawning and position of spines and pseudopodia...

Spinal anesthesia is increasingly viewed as a reasonable alternative to general anesthesia for lumbar spine surgery. However, the results of spinal anesthesia in elderly patients undergoing lumbar spine decompression and combined decompression and fusion procedures are limited in the literature. The aim of this study was to report a single institution's experience using spinal anesthesia in elderly patients undergoing lumbar spine surgery. A retrospective review was conducted using a prospectively collected database of consecutive lumbar spine surgeries performed under spinal anesthesia in patients 70 years or older at a single center between December 2013 and October 2015...

BACKGROUND: Anesthesia during the synaptogenic period induces dendritic spine formation, which may affect neurodevelopment. The authors, therefore, evaluated whether changes in synaptic transmission after dendritic spine formation induced by sevoflurane were associated with long-term behavioral changes. The effects of sevoflurane on mitochondrial function were also assessed to further understand the mechanism behind spinogenesis. METHODS: Postnatal day 16 to 17 mice were exposed to sevoflurane (2...
