SPSIPB Versus Deep SAPB for Analgesia After Breast Surgery

Breast surgery is one of the most common operations performed by General Surgery and may be associated with acute postoperative pain. Acute postoperative pain is an independent risk factor for the development of chronic pain after mastectomy. Various regional anaesthetic procedures have been tried to achieve better acute pain control and thus less chronic pain. The use of regional anaesthetic procedures in breast surgery is associated with a lower incidence of chronic pain, reduced morbidity, shorter hospital stay and less opioid requirement.

Interfascial plane blocks have become popular because they are easy to perform and safe. Since interfascial plan blocks are based on the injection of local anaesthetic between two fasciae, the complication rate such as nerve damage is very low. With this method, effective analgesia can be provided in various areas such as abdominal, thoracic and lumbar regions while reducing opioid consumption and avoiding neuraxial methods.

In randomised controlled trials investigating the efficacy of Serratus Anterior Plane Block for postoperative analgesia management after breast surgery, adequate analgesia was reported.

Serratus posterior superior intercostal plan block, a newly defined interfascial plan block, has been shown to provide a wide sensory blockade between intercostal muscles. Postoperative analgesic efficacy has been demonstrated in thoracic, breast and shoulder surgeries.

The aim of our study was to compared the postoperative analgesic efficacy of Serratus Anterior Plan Block and Serratus Posterior Superior Intercostal Plan Block in breast surgery.
