Anesthesia and ultrasound: riding the waves

Generating and Focusing the Ultrasound Waves Using Elastomer-based Capacitive Micro-Speakers

Ultrasound wave is a kind of waves with the frequency higher than the human audible frequency. Although ultrasound was first used for military identification purposes, it has been used for decades for various other applications, especially medical applications. Medical applications of ultrasound include diagnostic and therapeutic applications, such as for the treatment of cancer. In this paper,...

Ultrasound guided spinal anesthesia.

To the Editor: We write to share our recent experience with ultrasound (US) guided spinal anesthesia (SA) in a patient with scoliosis and lumbar spinal instrumentation. A 56-yr-old female patient was admitted for a total knee arthroplasty under SA. Her medical history included hypothyroidism, obesity (with a body mass index of 32 kg·m–2), and chronic low back pain. She had undergone multiple ba...

Ultrasound Guidance for Epidural Anesthesia

We propose an augmented reality system to automatically identify lumbar vertebral levels and the lamina region in ultrasound-guided epidural anesthesia. Spinal needle insertion procedures require careful placement of a needle, both to ensure effective therapy delivery and to avoid damaging sensitive tissue such as the spinal cord. An important step in such procedures is the accurate identificat...

Evaluation of the Bystander effect caused ultrasound waves on the MCF-7 cell line

Introduction: Non-target radiation effects are damages and effects that occur without the need for direct radiation exposure in cells. Bystander signals cause non-targeted irradiation effect that has been defined as radiation responses in which non-irradiated cells exhibit irradiated effects as a result of signals from adjacent irradiated cells. In this study, the bystander ef...
