Local infiltration analgesia does not reduce PCA use after periacetabular osteotomy .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2014;2(13):14 Acta Orthop. 2014 Apr;85(2):141-6Seventy patients scheduled to undergo periacetabular osteotomy were randomized either to receive or not receive local infiltration analgesia (LIA) with ropivacaine intra- and postoperatively. As all patients were treated with opioid based patient-controlled analgesia (PCA) postoperatively, the purpose was to determine whether LIA was effective at reducing the need for PCA (oxycodone) postoperatively. Over the first 4 postoperative days, there was no significant difference between groups in oxycodone consumption.

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Postoperative pain is often considerable following periacetabular osteotomy, requiring analgesia. Current methods of pain management include a psoas block, patient-controlled analgesia (PCA), and continuous epidural and spinal analgesia. While these treatments often lower pain experienced postoperatively, their associated side-effects have prompted researchers to consider alternative methods. Local infiltration analgesia has demonstrated efficacy in total knee and hip arthroplasty procedures, although its role in periacetabular osteotomy has yet to be established.
ما هو سؤال البحث الرئيسي؟
What is the efficacy of local infiltration analgesia (LIA) with ropivacaine for postoperative analgesia following periacetabular osteotomy, assessed over the first 4 postoperative days?
- There were no significant differences between the LIA and placebo group for oxycodone consumption over the first 4 PODs (POD1 p=0.66; POD2 p=0.86; POD3 p=0.57; POD4 p=0.85).
- VAS pain scores at rest were similar between groups 6h after surgery and on POD 1 (p=0.1 and 0.2, respectively). The LIA group demonstrated significantly lower mean pain scores at rest than the placebo group on POD2 (24 vs. 31), POD3 (19 vs. 31) and POD4 (18 vs. 28) (p<0.05).
- No significant differences in the TUG test or pain after the TUG test were noted between groups for the duration of the 4-day observation period (all p>0.05).
- Antiemetic use was similar between groups for the duration of the placement of the catheter.
ما الذي يجب أن أتذكره أكثر؟
Consumption of patient-controlled analgesia following periacetabular osteotomy was not decreased with the infiltration of ropivacaine at the end of surgery and for 2 days postoperatively.
كيف سيؤثر ذلك على رعاية مرضاي؟
From these findings, it would appear that local infiltration of ropivacaine alone is not sufficient to reduce the need for patient-controlled analgesia after periacetabular osteotomy, and that adverse events associated with opioid PCA (postoperative nausea and vomiting) would not be expected to decrease from its implementation. Whether LIA ropivacaine is an efficacious component in mulitmodal analgesia for periacetabular osteotomy remains to be determined in future studies.
