Summary
Brief summary
This study will compare T-lymphocyte function including regulatory T cell subset (CD4/CD25/FoxP3) and activated T cell panel (CD4/CD8/CD69/CTLA4) and postoperative pain score and complications between propofol-remifentail and sevoflurane anaesthesia in patients undergoing partial mastectomy with sentinel lymph node dissection due to breast cancer.
Sixty ASA 1-2 patients undergoing elective parial mastectomy with sentinel lymph node dissection will be randomly assigned into propofol-remifentanil or sevoflurane anaesthesia. Anaesthetic depth will be monitored with BIS with target ranges between 30-60. Blood pressure and heart rate will be maintained within 20 % of preoperative values. The administered vaso-active drugs will be recorded. Peripheral venous blood will be obtained before anaesthetic induction, before discharge from the post anaesthesia care unit, and 24 hour after end of operation and will be analyzed for regulated T-cell subset (CD4/CD25/FoxP3) and activated T cell panel(CD4/CD8/CD69/CTLA4). Postoperative pain scale score (0-10) and complications will be also evaluated.
