Summary

Patients undergoing total hip arthroplasty may experience severe postoperative pain. This is normally treated with opioids, which can cause side effects such as nausea, vomiting, obstipation and sedation. The hypothesis is that patients receiving peripheral nerve blockade of three nerves leading pain stimuli from the hip will experience less pain, will consume less opioid and therefore have less side effects, and will be mobilized more quickly than patients not receiving the peripheral nerve blockade.
