(Adapted from NHS AAA guideline G074: Fascia Iliaca Block (FIB))
FIB provides fast, effective analgesia and significantly reduces cumulative doses of opioids in patients with neck of femur (NOF) fracture. Reduced use of opioids and NSAIDS thus reduces side effects and complications.
Inclusion criteria
Confirmed or suspected fractured neck of femur.
Contraindications
- Patient refusal if patient lacks capacity use adults with incapacity (AWI).
- Patients who have already had a femoral or fascia iliaca block administered within previous 6 hours.
- Known sensitivity to local anaesthesia.
- Infection at the site of injection.
- Anticoagulant therapy (warfarin, clopidogrel, non-vitamin K antagonist oral anticoagulants (NOACS)) not an absolute contraindication - see guideline.
- Clotting disorder (INR >1.5, platelet count <80)
- Previous vascular surgery in affected limb.
- Difficulty identifying landmarks.
Prior to procedure
- Ensure IV access in situ and is patent.
- Ensure patient is monitored including NIBP, ECG, SpO2.
- Consent/AWI.
Equipment
- Dressing pack + sterile gloves
- Chloraprep stick 2%
- 18ga tuohy needle
- 1% lidocaine injection
- 5ml syringe
- 20ml syringe x2
- Orange needle 25G
- Drawing up needle (do not use to perform block)
- 0.25% levobupivacaine injection up to 40ml - maximum dose 2mg/kg
- Small dressing
- FICB sticker (DRS 6168)
Observations
- Record pain & NEWS 2 scores before the intervention.
- Repeat NEWS & pain score 15min, 30min, 1 hour, 2 hours and 4 hours following FIB, then 4 hourly thereafter.
- If pain scores are not improved after 30 min, ensure additional analgesia is given.
- Monitor patients for respiratory depression - may be prone to this after FIB provides effective pain relief, especially if morphine administered within previous 2 hours.
Local anaesthetic toxicity
- Observe patient for any signs of inadvertent intravascular injection such as circumoral tingling, light headedness, visual disturbances, seizures or arrhythmias.
- Immediately stop injection of local anaesthetic.
- Commence Basic Life Support if indicated.
- Call for help - 2222 call.
- Administer 100% oxygen + resuscitation.
- Call anaesthetist for urgent assistance.
- Consider lipid rescue therapy – located at bottom of Ortho cardiac arrest trolley.
