sites, angles, and letting the alcohol actually dry

The injection channel does not get busy often, and when it does it is because somebody has developed a lump. This fortnight it was three somebodies, and the resulting conversation covered rotation that people actually follow, needle gauge, and the difference between an injection-site reaction and a technique problem. Also the alcohol thing, again, forever.

What happened

  • Rotation schemes that require a diagram get abandoned, and the ones that survive are the ones you can do half asleep.
  • A 29 to 31 gauge pin in 8mm was the common setup reported, with a separate draw-up needle for anybody entering a vial repeatedly.
  • A small air bubble subcutaneously was described as a dose accuracy problem rather than a danger, which reassured two people and disappointed one.
  • Persistent lumps at one site were distinguished from stinging on entry, since the causes and the fixes are different.
  • chlorhex pointed out that most stinging complaints resolve when people wait ten seconds for the swab to dry.
