Need For Recovery
The Need for Recovery (NfR) score is a well validated tool to measure your need for recovery after the physical/mental strains of work. Originally designed for bus drivers, it has since been successfully used across may careers including recent studies in ED doctors and ACP’s.
Why?
- We would like to see how you’re doing (anonymously) – so please answer honestly
- If over time your score has increased or you think your score is high – please talk to any of the senior team

CT Abdo/Pelvis & Pregnancy Testing
Radiology are now requesting blood pregnancy testing reproductive females from 10-35days from last period. But what is wrong with urine pregnancy testing?

On rare occasions you may receive a pre-alert, where you want blood available for the patient when they arrive (for example in major haemorrhage). This process has been agreed with transfusion so this can be done safely and responsibly. Read more
Purple Glove Syndrome – Case
Is a rare complication of I.V. Phenytoin, which presents with a triad of: Pain, Oedema & Discolouration, typically in the hand.
In our case a child presented in status epilepticus, having received rectal diazepam from the ambulance crew, then 0.1mg/kg lorazepam in the ED, followed by 20mg/kg I.V. Phenytoin over 30 min, via a 24g cannula in back of the hand.
After intubation the patients thumb, index and middle fingers were all noted to be purple. Radial pulse was weak however, we saw good flow on ultrasound doppler in the ED. The patient had no cardiovascular Hx or FHx.
What the literature says
Mechanism (poorly understood)
- Phenytoin is highly Alkaline and may induce vasoconstriction and thrombus, resulting in leakage into the extravascular tissue.
- Phenytoin may precipitated when it mixes with acidic blood (More common in status patients rather than prophylaxis)
- I.V. Canulation may cause small tears promoting extravasation (In our case the cannula required repositioning on insertion)
Prevention
- Phenytoin infusion rate should be the lesser of 1-3mg/kg/min OR under 50mg/min (In our case the infusion rate was 22mg/min, less than 1mg/kg/min)
- Smaller hand veins should be avoided (As in our case, most reports in literature involve the use of hand veins)
- Use 20G cannula or larger (This is ideal for adults and older children)
- Ensure filter used with phenytoin infusions
Stages
- Dark purple – Pale blue discolouration occurs around or distal to injection site 2-12hrs after administration. (In our case approx 30 min)
- Discolouration and Oedema progresses around site and into fingers, hand and forearm over the next 12-16 hours
- Healing, starts at the periphery moving towards the injection site – most patients have a full recovery over 72hrs (few cases of necrosis requiring amputation have been reported
Treating
- Stop giving phenytoin
- Dry Warm Heat (moist heat my contribute to skin breakdown)
- Elevate
- Analgesia
- Regular neuromuscular assessments
- Avoid Cold (this will worsen the vasoconstriction)
- GTN patches have also been used in several of the cases but efficacy is unknown
Learning Points
- Avoid Hand veins for I.V. Phenytoin (this seems to be a contributing factor form the evidence, be it due to small size or more frequent injury of the vein though need to reposition?)
- Avoid Cannulas that required repositioning (increase chance of leaking)
- Use a big cannula (easier said than done in a fitting child)

Alprostadil
To maintain or restore patency of the ductus arteriosus
Only to be used in infants who are ventilated or where ventilation is immediately available
DO NOT DELAY IN STARTING Alprostadil if: there is clinical
suspicion of duct dependent CHD while waiting for paediatric cardiology opinion OR echocardiogram, even when in-house echo facilities are present.
