Response to ‘Single versus two-level superficial parasternal intercostal plane block: cadaveric evaluation of injectate spread with needle tip position on anterior surface of costal cartilage’

We thank Dr Dost for their interest in our recent cadaveric study assessing single versus two-level superficial parasternal intercostal plane (SPIP) injections with the needle tip located on the anterior costal cartilage. Dr Dost’s letter highlights the clinical and academic interest in regional analgesia for cardiac surgical patients and the need for ongoing research in this area.
