INTRAVENOUS INJECTION OF 10% CALCIUMGLUCONATE

The 10% calciumgluconate is often used to treat the
neonatal hypocalcaemia (1) While this drug has some stimulus character so
that we of the use 5% glucose solution to dilute it to two times of its
initial volume. And the injecting velocity is very low as 1ml/min (2). For
the neonates, we generally choose scalp vein as the location for transfusion
(3), because it has the advantages that its location is very superficial,
and the needle tends to be stable. While in the daily practice, we have
already met the uneasy condition that the drug sometimes can infiltrate the
subcutaneous tissue, and this can lead to terrible pain and, and more
severely, this can lead to focal tissue necrosis. And We have known that
the happening of this kind of injury has relations with the property of the
drug; the quantity of the drug, transfusion velocity; persistent time and
the concentration of the drug (4) for the neonates, the scalp vein is the
first choice for the nurses for liquid transfusion. But the fact that we
will create too many pinpricks on the baby��s scalp and too many vessels
here will be destroyed, and also the functions of valves of the vein in the
scalp is not so competent as the veins of other places stimulate us to make
this study, and the purpose is to compare different places of transfusion,
mainly their potential to prevent tissue necrosis.
Conclusions and Evaluations:
From this study we conclude that these two groups have
got very similar results, so the incidence of tissue necrosis has no
definite relationship with the site of injection.
