Cardiac puncture

Technique

Cardiac puncture is a suitable technique to obtain a single, good quality sample from a euthanised hamster or a hamster under deep terminal anaesthesia if coagulation parameters, a separate arterial or venous sample or cardiac histology are not required. It is appropriate for all strains of hamster.

A sample of up to 5 ml of blood can be obtained depending on the size of the hamster and whether the heart is beating. Blood samples are taken from the heart, preferably the ventricle, which can be accessed either via the left side of the chest, through the diaphragm, from the top of the sternum or by performing a thoracotomy. Blood should be withdrawn slowly to prevent the heart collapsing.
