Continuous quadratus lumborum block as part of multimodal analgesia after total hip arthroplasty: a case report.

BACKGROUND

Commonly used epidural or systemic analgesics for pain control after hip surgery carry risk for potential adverse effects. In contrast, the quadratus lumborum block (QLB) utilizes a simple and easy fascial plane technique and provides a wide area of sensory blockade. Thus, the QLB may be beneficial as analgesia after total hip arthroplasty.

CASE

Here, we report the case of an 83-year-old man who received a continuous transmuscular QLB as part of a multimodal analgesia after hardware removal and total hip arthroplasty. The patient received a continuous infusion of 0.2% ropivacaine at 8 ml/h through an indwelling catheter in addition to patient-controlled analgesia with intravenous fentanyl and oral celecoxib. The patient's pain scores did not exceed 4, and no additional analgesics were required until postoperative day 5.

CONCLUSIONS

Transmuscular QLB may be a suitable option for multimodal analgesia after total hip arthroplasty.
