Latest Updates

The Anesthesia Machine: Managing Exhaled and Waste Gases

    • CO2 absorbent material composition changes, including lithium-based absorbent, with lower risk of carbon monoxide and compound A production
    • New guidelines from the Malignant Hyperthermia Association of the United States on anesthesia machine preparation for MH-susceptible patients
    • Development of the Vapor-Clean filter, a charcoal-based filter that can remove traces of volatile anesthetic gases and prepare a machine for an MH-susceptible patient in less than two minutes

Imaging and Staging for Stomach Malignancy

    • Endoscopic ultrasonography (EUS) is a currently the mainstay in diagnosis and staging of gastric tumors.
    • EUS FNA offers precise diagnosis for primary tumors, local invasion, and lymph node sampling.
    • PET can evaluate response to chemotherapy with early identification of non-responders and treatment modification.

Medical Expulsive Therapy

    • Medical expulsion therapy may aid in the passage of distal ureteral stones and can be a useful adjunct in their management prior to more definitive surgical intervention.
    • Medical expulsion therapy may increase the rate of ureteral stone passage and decrease time for expulsion.
    • The data available at this time are strongest for the use of -antagonists in this role and may work best for distal ureteral stones from 5 to10 mm in size.

Electrical and Fire Safety in the OR

Ferenc E Gyulai, MD
    • Use of line isolation monitors to monitor the isolated power system ensuring that it is fully isolated from the ground
    • Use of ground fault circuit interrupter to help prevent individuals from receiving an electrical shock in a grounded power system by monitoring both sides of the circuit for the equality of the current flow
    • Discovery that sevoflurane and desiccated CO2 absorbent can undergo exothermic chemical reactions causing fires prompting preventive measures

The Respiratory System: Physiologic Assessment and Real-world Application

    • Reflectance Pulse Oximetry: The use of backscattered light rather than transmitted light can be helpful in low-signal settings.
    • Improved Signal Processing for Pulse Oximetry: Proprietary algorithms and advances in signal processing have improved the precision of pulse oximetry.
    • Calorimetric Detection: Colorimetric CO2 detection can be used to ensure nasoenteric placement rather than respiratory placement.
