Avoiding the Internal Mammary Artery During Parasternal Blocks: Ultrasound Identification and Technique Considerations.

J Cardiothorac Vasc Anesth 2021 Jun 16;35(6):1594-1602. Epub 2020 Nov 16.

Department of Anesthesia and Cardiac Surgery Intensive Care Unit, San Michele Hospital, Maddaloni, Caserta, Italy.

Fascial plane chest wall blocks are an integral component to optimal multimodal postoperative analgesia in breast and cardiothoracic surgery, facilitating faster functional recovery and earlier discharge. Pectoral nerves block and serratus plane block have been used to treat postsurgical pain after breast and cardiothoracic surgeries; however, they cannot be used to anesthetize the anterior chest wall. Ultrasound parasternal block, or pectointercostal fascial block and transversus thoracis muscle plane block are two novel ultrasound-guided anesthetic and analgesic techniques that block the anterior cutaneous branches T2 to T6 intercostal nerves, providing anesthesia and analgesia to the anterior chest wall.

Luminescent Spectral Rulers for Noninvasive Displacement Measurement through Tissue.

ACS Sens 2020 03 6;5(3):711-718. Epub 2020 Mar 6.

Department of Chemistry, Clemson University, Clemson, South Carolina 29634, United States.

A luminescent spectral ruler was developed to measure micrometer to millimeter displacements through tissue. The spectral ruler has two components: a luminescent encoder patterned with alternating stripes of two spectrally distinct luminescent materials and an analyzer mask with periodic transparent windows the same width as the encoder stripes. The analyzer mask is placed over the encoder and held so that only one type of luminescent stripe is visible through the window; sliding the analyzer over the encoder modulates the luminescence spectrum acquired through the analyzer windows, enabling detection of small displacements without imaging.
