Highlights from this day
- deadspace — i mark the rotation in a notes app because the marks fade and i lost track twice 14:19
- deadspace — i keep the sharps bin next to the fridge so the whole thing happens in one place 14:40
- batch_variance — warming the vial in your hand for a minute is the cheapest comfort improvement there is 15:59
- VialBot — Inter-lab diff for lot E-2205: 98.6% vs 99.4%. Within expected range. 16:02
- batch_variance — a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call the difference between 29G and 31G is real but small. the difference… 18:27

rotate

pinch
bleeding a little means you nicked a small vessel. it is not a technique failure
sharps bin
update on the earlier thing do not reuse pins. it is not about sterility so much as the tip being blunt after one pass

never recap a used pin. that is how people stick themselves
do you pinch or stretch
let the alcohol dry. that is ninety percent of "my injections sting", we shall see
cold from the fridge genuinely stings more. i let it sit out for ten minutes

i changed nothing except letting the swab dry and the stinging stopped completely

warm it first
29G in 8mm or 12.7mm for abdomen
the needle went in fine but it stung going in, alcohol or the compound
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

do you use the insulin syringe for both drawing and injecting
does injecting a cold vial hurt more or am i imagining it
90 degrees works fine if you have the tissue for it. 45 if you do not
warming the vial in your hand for a minute is the cheapest comfort improvement there is

31G 8mm
Inter-lab diff for lot E-2205: 98.6% vs 99.4%. Within expected range.
45 degrees
a proper sharps bin costs almost nothing and pharmacies will take it back
thats normal
31G 8mm for everything. i tried the 12.7mm once and never went back, your mileage will differ
technique probably
nobody here should be telling you where to inject. we can tell you what we do
do you count to five before withdrawing
try the thigh
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
dont recap
sorry to jump in absorption differences between subcutaneous sites are small for a weekly compound
whats your sharps disposal setup, mine is a jar and i know thats wrong
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
update on the earlier thing is bruising more about the needle or the aftercare
