简要总结
The hypothesis of this study is that isolated use of local periarticular levobupivicaine injection during primary hip arthroplasty would improve post-operative pain control. Patients were randomised in the operating room to receive either a periarticular infiltration, or a placebo consisting of Saline. Morphine and analgesic consumption was recorded for each patient, while the modified McGill pain scale was used to determine the adequacy of analgesia and the benefit of the peri-articular infiltration. 91 patients were recruited, with 45 patients in the treatment group and 46 controls. The results were assessed after one year, once all the information from both treatment groups was collected.
详细描述
The efficacy of periarticular injections during total knee arthroplasty is well established but there is little published data on their effect in primary hip arthroplasty. We hypothesized that isolated use of local periarticular levobupivicaine injection during primary hip arthroplasty would improve post-operative pain control. A double blinded, randomised, placebo-controlled trial on patients undergoing primary hip arthroplasty was performed. Patients were randomised in theatre to receive either a periarticular infiltration of 150mg levobupivicaine in 60mls of 0.9% Saline, or a placebo consisting of 60mls 0.9% Saline. Morphine and analgesic consumption was recorded for each patient, while the modified McGill pain scale was used to determine the adequacy of analgesia and the benefit of the peri-articular infiltration. 91 patients were recruited, with 45 patients in the treatment group and 46 controls. The results were assessed after one year, once all the information from both treatment groups was collected.

研究组 & 干预措施
Levobupivacaine
Levobupivacaine is indicated for local anaesthesia including infiltration, nerve block, ophthalmic, epidural and intrathecal anaesthesia in adults; and infiltration analgesia in children
干预措施: Levobupivacaine (Drug)
Saline
Saline (also saline solution) is a general term referring to a sterile solution of sodium chloride (NaCl, more commonly known as salt) in water but is only sterile when it is placed intravenously, otherwise, a saline solution is a salt water solution.
干预措施: Saline (Drug)
结局指标
主要结局
To determine a significant difference (p>0.05) in morphine consumption between the two treatment groups post-operatively.
时间窗: 1 year
The modified McGill pain scale was administered to determine the adequacy of analgesia and the benefit of the peri-articular infiltration. In addition, morphine and analgesic consumption was recorded for each patient. The results were assessed after one year, once all the information from both treatment groups was collected.
次要结局
- To analyse the length of stay for between both treatment groups(Average 6 days (based on precise day of discharge))
