Technique for microsphere injection

Comparison between hydrogen clearance and microsphere technique for rCBF measurement.

Regional cerebral blood flow was measured repeatedly in anesthetized and immobilized cats under various experimental conditions by recording the clearance of inhaled hydrogen with inserted platinum electrodes and by recording the distribution of 15 mu microspheres labeled with 3 different radioisotopes. The values for both methods in normal cortical tissue were comparable (75.7 +/- 23.5 ml/100 ...

Subcutaneous insulin injection technique

The aim of this article is to update general nurses’ knowledge of insulin injections. The importance of choosing the optimal injection site for the prescribed insulin regimen and matching the site with the needle length and injection technique is discussed. The appropriate storage of injection devices between use, resuspension of cloudy insulins, and safe disposal of pen needles are also highli...

Intravitreal injection technique

This article describes how to give an intravitreal injection of an anti-VEGF drug. At present, the majority of intravitreal injections are administered by doctors; however, experience in the UK has shown that trained nurses can give these injections as safely as ophthalmologists. The single most important thing to remember is that an intravitreal injection is an intraocular operation, and shoul...

Insulin injection technique.

For many years after the introduction of insulin the recommended injection technique was to raise a skin fold and insert the needle at an angle of 45°. With the advent of shorter 12-13 mm needles these two instructions were no longer thought necessary; the belief was that a full depth perpendicular injection would allow consistent deposition of insulin into subcutaneous adipose tissue.' This te...
