NCT06480045

Brief Summary

The investigator's goal in this study is to apply PECS II block, before starting surgery, by either conventional USG or artificial intelligence integrated USG to patients who will undergo mastectomy under general anesthesia to determine the effect of the block on hemodynamics and opioid consumption in the intraoperative period. Besides, the investigatorwanted to investigate the contribution of artificial intelligence integrated USG use in the success of a 4-year anesthesiology resident for imaging the injection site.

Outcome Measures

Primary Outcomes (1)

  • Pain in the postoperative period was evaluated using the VAS score.

    The researchers investigate whether postoperative pain increases or decreases, using the VAS score at the postoperative anesthesia care unit, at postoperative 6 hours, 12 hours, and 24 hours.

    24 hours

Secondary Outcomes (1)

  • Incorporating the use of AI applications reduces the time required to block.

    During the procedure.

Model Details: 70 patients with ASA I-II, between the ages of 18-75, who were scheduled for mastectomy surgery were included in the study. An anesthesiology resident under the supervision of senior anesthesiologist, performed a PECS II block with AI-integrated USG or conventional USG (Group AI-USG and Group USG) after randomization. Block was performed after induction of general anesthesia. Patient data in terms of hemodynamic changes in the intraoperative period, opioid consumption, and postoperatively hemodynamics, pain scores (VAS), postoperative opioid (tramadol administered with a patient-controlled analgesia pump) and, if necessary, rescue analgesic agent (non-steroidal antiinflammatory agent) consumption were monitored in the post-anesthesia care unit, and at postoperative 6., 12. and 24.hours.
