As much as I love both IN medications (mostly midaz for anxiety,
fentanyl for pain) and ketamine, I have not found IN Ketamine to be
The two main challenges are dosing and the inconsistent effect.
With the general volume max of 1 cc/nostril for IN medications, and
the higher concentration of ketamine of 100mg/cc, it is difficult of
achieve a 9 mg/kg dose once you are
dealing with a child who weighs around 20kg and above.
More importantly, the effect is variable. Plenty of studies (mostly
adult) have shown that low dose ketamine (0.5-1 mg/kg) can be
effective for pain control. But to achieve the desired dissociative
amnestic ketamine state you need to push the dose up higher to 6-9
mg/kg and even then it is often not enough to do more painful
procedures (such as fracture reductions). On the other hand,
Intramuscular ketamine (at 4-5 mg/kg) works more consistently so when
I am looking for non-IV option I don't bother with IN when the IM
route works better.
Hope this helps,
