Brief Summary

The Serratus Posterior Superior Intercostal Plane (SPSIP) block is a novel regional anesthesia technique targeting the dorsal rami and intercostal nerves (T2-T6), providing sensory blockade to both the posterior and lateral aspects of the chest wall. By blocking these nerves at a more posterior location, the SPSIP block can potentially offer broader and more comprehensive analgesia for breast surgeries, including the axillary and deeper structures of the breast. This makes it a promising alternative or adjunct to the existing regional techniques used in breast cancer surgeries

Outcome Measures

Primary Outcomes (1)

  • Post operative pain relief

    the level of postoperative pain as assessed by the Numerical Rating Scale (NRS) at rest and during movement at predefined intervals: 1 hour, 6 hours, 12 hours, and 24 hours post-surgery. The NRS is a validated tool that ranges from 0 (no pain) to 10 (worst imaginable pain).

    24 hours

Secondary Outcomes (3)

  • Total Opioid Consumption

    24 hours

  • Time to First Analgesic Request

    24 hours

  • Incidence of Postoperative Nausea and Vomiting (PONV)

    24 hours
