Intertransverse process block: A narrative review
Authors' conclusion
However, due to the limited evidence base, its safety and efficacy remain inadequately understood, and few clinicians are proficient in performing ITPB.
Study context
- Population
- Patients undergoing breast, cardiothoracic, abdominal and spinal surgery, and trauma patients
- Comparison
- Mid-point transverse process to pleura block vs Multiple-injection costotransverse block vs Costotransverse foramen block vs Subtransverse process interligamentary plane block
- Outcome
- Intertransverse process block (ITPB): anatomy, mechanism, technique, clinical use
Main finding
As reported in the abstract
- All 4 intertransverse process block (ITPB) types target the retro-superior costotransverse ligament space; differ slightly in needle entry approach and tip target
- Easy to locate, quick to perform, reliable analgesic effects
- Can effectively reduce risk of pneumothorax, hematoma and intraspinal injection
- Used for anaesthesia and analgesia in breast, cardiothoracic, abdominal and spinal surgery and for pain relief in trauma
- Narrative review
