Abstract
Background: The Local infiltration analgesic (LIA) technique has widely been used to

reduce opioid requirements and improve postoperative mobilization following total hip

arthroplasty (THA). However the evidence for LIA in THA remains to be clarified.

Purpose: To evaluate whether a single shot LIA in addition to a multimodal analgesic

regimen would reduce acute postoperative pain and opioid requirements after THA.

Material and Methods: 116 patients undergoing primary THA under spinal anesthetic were

included in this randomized double- blinded placebo- controlled trial. All patients received

oral opioid-sparing multimodal analgesia; Etoricoxib, Acetaminophen and Glucocorticoid.

The patients were allocated to receive either 150 ml Ropivacain 2mg/ml and ½ ml

Epinephrine 1mg/ml, or 150 ml saline 0. 9 %. Rescue analgesic consisted of Morphine and

Oxycodone as needed. The primary endpoint was pain during mobilization in the recovery

unit. Secondary endpoint was pain during mobilization the day after surgery and total

postoperative opioid requirements the first postoperative day.

Results: Pain during mobilization in the recovery unit did not differ significantly between the

two groups (p=0. 7 Mann-Whitney U-test) neither did pain score during mobilization the day

after surgery (p=0. 2 Mann-Whitney U-test). There were no significant difference between the

two groups in postoperative consumption of opioids the first postoperative day.

Conclusions: LIA provides no extra analgesic effect after THA in addition to the multimodal

analgesic regimen used in this study.
