Highlights from this day
- luerlok — i keep the sharps bin next to the fridge so the whole thing happens in one place 17:20
- truncation_tru — do not aspirate for a subcutaneous injection, there is nothing to aspirate for 17:52
- coa_or_cope — the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small 18:32
let the alcohol dry. that is ninety percent of "my injections sting"
do you count to five before withdrawing
cold from the fridge genuinely stings more. i let it sit out for ten minutes

90 degrees works fine if you have the tissue for it. 45 if you do not
[edited]do not aspirate for a subcutaneous injection, there is nothing to aspirate for

do not reuse pins. it is not about sterility so much as the tip being blunt after one pass
anyone got a rotation map they would share
thats normal

how do you avoid hitting the same spot twice when the marks fade
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

welts at the site are usually a mild local reaction and rotation sorts it
update on the earlier thing 29G in 8mm or 12.7mm for abdomen
dont recap
bleeding a little means you nicked a small vessel. it is not a technique failure
absorption differences between subcutaneous sites are small for a weekly compound
a proper sharps bin costs almost nothing and pharmacies will take it back, we shall see
technique probably
warming the vial in your hand for a minute is the cheapest comfort improvement there is

ok so i keep getting a small welt at the site, technique or reaction
quick one a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
not a problem
how slowly should you actually push
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
update from 12 months ago: switched to a fixed rotation and the site reactions stopped
[edited]i mark the rotation in a notes app because the marks fade and i lost track twice
push slowly. fast is what causes the ache afterwards
