About this study
Official title: The Effect of the Quadro-Iliac Nerve Block on Postoperative Pain in Hip Surgery
In this single-center retrospective study, patients who underwent hip surgery between May 2025 and November 2025, with American Society of Anesthesiology (ASA) physical status I-III, aged 18 years and older, were screened. Patients who did not undergo a block for postoperative analgesia and who used patient-controlled analgesia were included in the control group. Patients who underwent QIPB and used patient-controlled analgesia were included in the block group. Patients' postoperative tramadol consumption, pain scores assessed using the Numerical Rating Scale, and rescue analgesia requirements were recorded. The primary endpoint was total opioid consumption over 24 hours, and the secondary endpoints were postoperative pain scores and rescue analgesia requirements.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In this single-center retrospective study, patients who underwent hip surgery between May 2025 and November 2025, with American Society of Anesthesiology (ASA) physical status I-III, aged 18 years and older, were screened. Patients who did not undergo a block for postoperative analgesia and who used patient-controlled analgesia were included in the control group. Patients who underwent QIPB and used patient-controlled analgesia were included in the block group. Patients' postoperative tramadol consumption, pain scores assessed using the Numerical Rating Scale, and rescue analgesia requirements were recorded. The primary endpoint was total opioid consumption over 24 hours, and the secondary endpoints were postoperative pain scores and rescue analgesia requirements.
