Nerve detection with optical spectroscopy for regional anesthesia procedures

Nerve Stimulator with High Reliability for Assistance in Regional Anesthesia

Peripheral nerve stimulation in regional anesthesia.

Peripheral nerve stimulation has a long history in regional anesthesia. Despite the advent of ultrasound-guided peripheral nerve blockade, nerve stimulation remains a popular technique used alone or, now, in combination with ultrasound-guided techniques. In light of this evolving utility of nerve stimulation, this is an appropriate time to review the basic concepts and knowledge base of this hi...

Ultrasound-Guided Regional Anesthesia for Procedures of the Upper Extremity

Anesthesia options for upper extremity surgery include general and regional anesthesia. Brachial plexus blockade has several advantages including decreased hemodynamic instability, avoidance of airway instrumentation, and intra-, as well as post-operative analgesia. Prior to the availability of ultrasound the risks of complications and failure of regional anesthesia made general anesthesia a mo...

Role of Anesthesia in Performing Invasive Procedures for Children with Malignancy

Background: Pediatric oncology patients frequently need several painful procedures during their diagnostic and therapeutic process. During the past decades, most centers abroad have developed safe and effective protocols for procedural sedation and analgesia in children. This report describes procedural sedation and analgesia as performed in pediatric oncology unit and tries to report success o...

Optical spectroscopy for detection of neoplasia.

Fluorescence and reflectance spectroscopy provide the ability to assess tissue structure and metabolism in vivo in real time, providing improved diagnosis of pre-cancerous lesions. Reflectance spectroscopy can probe changes in epithelial nuclei that are important in pre-cancer detection, such as mean nuclear diameter, nuclear size distribution and nuclear refractive index. Fluorescence spectros...
