Serratus-Intercostal Fascial Plane Block (SIFP block)
The patient is positioned in the prone position, the probe is used to locate in cross-section the T4 spinous process. Next, using a lateral scan, approximately 3 cm away, the costotransverse joint is located, and then change to sagittal ultrasound vision. By locating the intertransverse line with the probe, the following anatomical structures can be identified: three longitudinal muscles (trapezius, rhomboid, erector spinae). The needle enters in a single punction at an angle of 45º, in the cranio-caudal direction, until it touches the apex of the costotransverse image. Subsequently, 30 cc of 0.25% bupivacaine are administered in the depth of the erector spinae, which will remain elevated.
The patient is positioned supine, with the ipsilateral upper limb extended. The clavicular external third line is drawn. In parallel, the lower costal line and the infraclavicular space are highlighted. The probe obtains an image that allows the identification of the pectoralis major and pectoralis minor. If colour Doppler is added, the acromiothoracic artery is identified and must be avoided. The needle enters at an angle of 45º from medial to lateral, and 20 cc of 0.25% bupivacaine are administered. Next, needle advances in the interfascial space between the pectoral minor and serratus anterior and 10 cc of 0.25% bupivacaine are administered.
The patient is positioned supine, with the ipsilateral upper extremity at a 90º angle. The fourth, fifth, and sixth intercostal spaces are identified in the mid-axillary line. In coronal section, it is possible to appreciate the subcutaneous cellular tissue, the serratus anterior, and the intercostal muscles. The needle is introduced at an angle of 30º. From caudal to cranial and resting the needle on the fourth rib, 30 cc of 0.25% bupivacaine are administered between the serratus anterior and lateral intercostal muscles.
