Local Infiltration Analgesia (LIA) technique for pain control after total Joint replacement surgery

บทคัดย่อ

 Background : Total Joint Replacement surgery usually causes significant postoperative pain and it is one main reason for worrisome patients to postpone or deny surgery, aside from delay ambulation and hence delay recovery and discharge. Various methods of postoperative pain control have clinically been    applied nowadays. The novel, Local Infiltration Analgesia (LIA) technique, provides satisfactory, effective, safe, simple and practical pain control to patients       underwent total joint replacement surgery .

Method  : 100 patients were recruited into this study. 50 patients were having total knee replacement (TKR) surgery whereas the others 50 patients were having Total Hip replacement (THR) surgery.  All surgeries were done by same surgeon and same surgical technique. Difficult, revision and  infected cases   were excluded. All patients received the LIA pain control techinque.Difficult,revition and infected cases were excluded. All patients rsceived the AIL pain control techinque, by indwelling spinal catheter into the joint after surgery was done and before wound closure.Visual analogue pain score was evaluated immediately after surgery and throughout 2 days of postoperative care. The amount of Morphine given to the patients and level of pain score were collected and analyzed. 

Results  : Out of 50 patients underwent total knee replacement, there were 5 patients had pain score more than 4 and received Morphine to control the pain . Whereas, 3 of 50 patient s underwent total hip replacement had pain score higher than 4 and received Morphine. There was no serious complication related to this pain control technique. 

Conclusion  : Local Infiltration anesthesia ( LIA) pain control technique is simple but very effective to decrease postoperative pain. Most of patients were         satisfied with only minimal postoperative pain. There was no side effect such as drowsiness and vomiting unlike in those patients who received Morphine.And there waas no serious complication or unexpected events.
