Initiating therapeutic hypothermia for out-of-hospital cardiac arrest pre-hospital does not improve survival or neurological outcome.

For emergency medical services with low VF survival rates (<20%), early rhythm analysis improves survival, whereas in services where VF survival rates are high (>20%) delayed rhythm analysis with focus on immediate CPR instead improves survival.

Modelling implementation of a clinical decision rule to identify children at very low risk of significant intra-abdominal injury after blunt trauma:
• Saved on average US$55 per child.
• Avoided a CT scan in 1 in 10 children.
• Missed 1 in 2,000 intra-abdominal injuries requiring acute intervention.

After reviewing available evidence the Neuropathic Pain Special Interest Group could only recommend:
1. Epidural injections for herpes zoster neuropathic pain.
2. Steroid injections for radiculopathy.
3. Spinal cord stimulator for failed back surgery syndrome or Complex Regional Pain Syndrome type 1

If a patient requires beta blockade for cardiac reasons they should have it.
If they do not then they should not.
