슬관절 전치환술에서 수술 중 관절 주위 주사의 단기 마취 효과

Purpose: The purpose of this study was to evaluate the clinical results of intraoperative periarticular injection for osteoarthritic patients who are treated with total knee arthroplasty (TKA). Materials and Methods: Forty patients (2 males and 38 females) who underwent TKA under general anesthesia from January 2007 to May 2007 were enrolled in this study. We classified 20 cases to the injection group and 20 cases to the control group. For the injection group, we injected ropivacaine 40 mg, ketolocac tromethamine 2 mg, epinephrine 0.5 cc and morphine 0.8 cc to the periarticular soft tissue before inserting the prosthesis, and the same amount of saline was injected in the control group. We assessed the clinical results according to preoperative and postoperative range of motion (ROM), the visual analogue scale (VAS), and the dosage of the patient controlled anesthesia (PCA) in both groups. Results: There was no significant difference in preoperative ROM and VAS between the groups (p＞0.05). However, significant differences between the groups were reported for the postoperative ROM at 6 and 12 hour. In terms of the VAS, it showed significant differences between the groups at 6 and 12 hours and at the first and second days after operation. The dosage of PCA was significantly lower at postoperative 6 and 12 hours. Conclusion: For the patients treated with TKA, periarticular injection to the operation site is supposed to be an effective method at the early stage for recovery of the ROM, the postoperative pain control and to decrease of the PCA dosage.
