How to give injections
Previous to you even think of injecting, inspect the needle and make sure that it is sharp and that the point is not injured in any way.
Charge the syringe with the right quantity of the substance to be injected and discard the drawing-up needle. Fit a new, sharp needle onto the syringe and hold the syringe about 20 to 25 mm (3/4 to 1 inch) from the front of the barrel, where the needle has been built-in onto it, between the thumb and forefinger of your working hand.
Lift the skin up and notice the way the grain of the skin runs.
For intramuscular (IM) injection, grasp the flesh, starting with your fingers about 30 mm (11/2 inches) apart and draw it together into a ridge.
Turn the syringe so that the taper of the needle is on one side: it must not be on top or beneath the needle.
Insert it quickly, easily and certainly into the skin and carry on forward until the needle has gone through to the desired depth.
Let go the skin/muscle now and use the thumb and forefinger of your hand to hold the front of the syringe, so that your working hand can move back to the plunger.
Pull back on the nozzle to make sure that you have not hit a blood vessel. If the syringe does not draw up blood, gradually depress the plunger.
Beware: some of the powder postponement, notably the penicillin derivatives, are thixotropic and block the needle solidly when pressure is applied. The only solution here is to use a thicker needle. The oily injectables tend to be viscous and must be penetrate slowly, to give the tissue enough time to scatter them.
Once the dose has been managed, press down over the site of the injection and take away the needle quickly, but quietly.
For intravenous injection, rotate the syringe so that the tapering point of the needle is down and you can clearly see the hole.
Look for a robust vein and disinfect as explained above .You have applied the cuff and pumped it up, I assume? Press down on the chosen blood vessel with the clean thumb of your hand and hold it stable.
Slope the syringe so that it is at a high angle and give a quick, short jab into the vein, ensuring that you do not go through it.
Once again change hands, with the hand guiding the syringe as the working hand lowers and infiltrates the blood vessel.
Once again, draw back on the plunger. If the barrel draws up blood, you are home and parched.
A point to watch when managing I.V. medications is this: always put in the needle so that it points in the direction of the blood flow. In this way the solution and the blood travel in the same direction and the medication does not impede or go against the direction of the flow.
If possible, always administer I.V. medications using a "butterfly" that can be taped to the skin so that the needle does not move around and possibly re-emerge someplace else.
