Brief summary
Prospective cohort assessing the effects of ankle block (local infiltration analgesia) on duration of analgesia, pain, opioid consumption, and patient satisfaction.
Interventions
PROCEDUREAnkle block
Injection of local anaesthetics at the level of the ankle blindly (local infiltration analgesia). The dose, volume, and type of local anaesthetic will be registered.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Duration of analgesia, measured as time to first pain | 24 hours | Duration of analgesia measured as time to first pain as reported by the patient. The duration of analgesia is expected to be less than 24 hours. If the duration of analgesia exceeds 24 hours, follow-up will be performed until return of normal sensation is ensured. Duration of analgesia will be set to 24 hours for participants having a duration of analgesia exceeding 24 hours. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Participants with failed block | 24 hours | Failed block will be defined as participants experiencing pain (NRS \> 0) prior to discharge from the post-anaesthesia care unit. |
| Pain at 6 hours postoperatively, measured on the NRS | 6 hours | Pain at 6 hours postoperatively measured on the NRS as reported by the participant. |
| Pain at 24 hours postoperatively, measured on the NRS | 24 hours | Pain at 24 hours postoperatively measured on the NRS as reported by the participant. |
| Pain in the post-anaesthesia care unit, measured on the Numerical Rating Scale (NRS) | 24 hours | Pain in the post-anaesthesia care unit as reported by the patient on the NRS (0 to 10 points, 0 no pain, 10 worst perceiveable pain). The assessment will be performed just prior to discharge from the post-anaesthesia care unit. |
| Participant satisfaction related to ankle block | 24 hours | Participants will be asked if they wanted a longer block duration, if they wanted a shorter block duration, and if block duration was adequate (binary outcomes, yes/no). |
| Unplanned admission | 24 hours | Most participants will be discharged directly from the post-anaesthesia care unit and some will have planned hospital admission following surgery. Unplanned admission will be defined as an admission that was not planned in advance. The reason for admission will be recorded. |
| Postoperative nausea and vomiting | 24 hours | Incidence of postoperative nausea and vomiting. |
| Cumulative opioid consumption at 24 hours postoperatively | 24 hours | Cumulative opioid consumption at 24 hours postoperatively. Opioid consumption will be converted to intravenous morphine equivalents. Intraoperative opioid use will not be included. |
