When drawing blood, the needle is typically inserted at a 15 to 30-degree angle for veins located close to the surface, such as in the antecubital fossa (the crease of the elbow). For deeper veins, a slightly higher angle may be appropriate, but generally, a 15 to 30-degree angle is ideal for most venipunctures. Proper technique helps ensure a successful draw while minimizing discomfort for the patient.

The major risk of drawing blood or starting an IV is

About a right angle (90 degrees) to the chest, intercostal, into the pleural lining and not into the lung.

Hemolysis
The major risk of drawing blood and starting IVs includes infection, bleeding, nerve damage, and bruising at the site of insertion. Additionally, there is a risk of complications if the needle is inserted incorrectly, such as infiltration or phlebitis.

15-30 degrees
Healthcare professionals can prevent a hematoma when drawing blood by applying gentle pressure to the puncture site after removing the needle, ensuring proper needle insertion angle and depth, and avoiding excessive probing or movement of the needle during the procedure.
I think the needle will be inserted in lumbar 3 and 4 for epidural.
