Respiratory Recovery in a Critically Ill Patient With Rib Fractures Using the Serratus Posterior Superior Intercostal Plane Block: A Case Report

We present a case of a patient with multiple rib fractures who was managed in the intensive care unit using a serratus posterior superior intercostal plane (SPSIP) block. The SPSIP block is a relatively new interfascial plane block technique that provides broad thoracic dermatomal coverage for analgesia. In trauma patients with multiple rib fractures, pain control, preservation of respiratory function, prevention of pulmonary complications, and facilitation of early mobilization are important. This case suggests that the SPSIP block may represent a safe, effective, and opioid-sparing analgesic option in critically ill patients with thoracic trauma–related respiratory compromise and warrants further investigation.
