Official title
A Retrospective Evaluation of Systemic Analgesia, Rhomboid Intercostal Block, and Combined Rhomboid Intercostal Block With Deep Parasternal Intercostal Plane Block After Mastectomy
Overview
This retrospective observational study evaluates postoperative pain outcomes in patients undergoing elective mastectomy who received systemic analgesia, rhomboid intercostal block (RIB), or combined rhomboid intercostal block with deep parasternal intercostal plane block (RIB + DPIPB). Medical records from October 2024 to October 2025 will be reviewed. Primary outcomes include pain scores within the first 24 hours, with secondary outcomes including opioid consumption, additional analgesic requirements, patient satisfaction, and early postoperative complications. All data will be analyzed retrospectively and anonymously.
Interventions
- Other Analgesic Strategy
Systemic Analgesia: Postoperative pain was managed using standard systemic analgesic medications as part of routine clinical care. Rhomboid Intercostal Block (RIB): Postoperative analgesia was provided using an ultrasound-guided rhomboid intercostal block performed as part of routine clinical practice. RIB + Deep Parasternal Intercostal Plane Block (DPIPB): Postoperative analgesia was provided using a combination of ultrasound-guided rhomboid intercostal block and deep parasternal intercost
Primary outcome measures
- Postoperative Pain Score (VAS) [Time frame: Within the first 24 hours after surgery (postoperative 1, 6, 12, and 24 hours).]
