유방절제술 후 광배근 근피판을 이용한 즉시 유방재건술 환자에서 경추 경막외 및 정맥내 자가통증조절의 효과 비교

Abstract

BACKGROUND: Breast reconstruction following mastectomy has become increasingly popular in recent years. The purpose of this study was to compare the efficacy of cervical epidural patient-controlled analgesia (CEA) and intravenous patient-controlled analgesia (IV-PCA) for controlling the postoperative pain and the side effects after mastectomy with immediate Latissimus dorsi (LD) flap breast reconstruction. METHODS: Sixty patients who were to undergo mastectomy with immediate LD flap breast reconstruction were randomly assigned to receive CEA [Group CEA, (n = 30), 0.15% ropivacaine + fentanyl 4 microg/ml] or IV-PCA [Group IV-PCA (n = 30) fentanyl 20 microg/kg + ketorolac 3 mg/kg] for postoperative pain control via a PCA pump (basal rate: 2 ml/h, bolus: 2 ml, lock out interval: 15 min) after their operation. Before general anesthesia, an epidural catheter was inserted at the cervical (C)7-thoracic (T)1 level in the patients of the CEA group. The resting visual analogue scale (VAS) for pain, the systolic blood pressure, the heart rate and the side effects were recorded for 48 hours after operation. RESULTS: The VAS at rest was significantly lower in the CEA group than that in the IV-PCA group at 16 hours after surgery. The CEA group required less additional analgesics as compared with the group IV- PCA. There were no significant differences in the systolic blood pressure, the heart rate and the incidence of side effects between the two groups. CONCLUSIONS: We conclude that cervical epidural analgesia, as compared with intravenous patient-controlled analgesia, provides effective pain control and it shows a similar incidence of side effects after mastectomy with immediate LD flap breast reconstruction.
