E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Local infiltration analgesia a multimodal pain management strategy in total hip arthroplasty. The Anterior Supine Intermuscular technique for THA procedures will allow the patient to mobilize much earlier postoperatively, however it has been hypothesized that it will give more pain direct postoperative. This study will investigate the effect of LIA in combination with the ASI technique.

|
E.1.1.1 | Medical condition in easily understood language |
Patients with a hip replacement surgery will have pain after the surgery. Due to this pain early mobilization is not possible. Local infiltration might reduce the pain after the operation. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Determining the outcome of reversed and antegrade LIA in THA with ASI by analysing postoperative pain with the 100 mm Visual Analogue Scale (VAS), length of hospital stay, the amount of postoperative consumption of opioid pain medication as well as the consumption of other pain medication |

E.5 End points |
E.5.1 | Primary end point(s) |
- Pain score (VAS) at day 1 at multiple moments: 1, 4 and 8 hours after operation in rest, and while and direct after mobilization starting at 4-6 hours after operation. At day 2 until the day of discharge at two moments.
- Cumulative consumption of opioid medication and pain medication.
- Length of Hospital Stay by amount of nights and number of hours between operation and discharge.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
- VAS: 1,4,8 hours after operation in rest and direct after mobilization at 4-6 hours after operation. At day 2 until discharge at 2 standardized moments: morning and afternoon.
