This slideshow introduces the basic concepts around intravenous cannulation. Whilst the context is midwifery this slideshow is also suitable for nurses and medical staff.

21. Local complications Treatment – stop infusion, remove cannula, resite, apply warm compress, elevate and rest arm Prevention – regular monitoring of IV site & cannula, appropriate choice of site, secure taping, ask woman to report any discomfort

26. Sodium chloride 0.9% isotonic Most commonly used - administer drugs, eg syntocinin, magnesium sulphate. Replaces H20, Na, C in dehydration. Haemodilution can occur. Overload. Hartmann's (lactated Ringer's solution) isotonic Epidural - pre-loading dose to counter-act hypotension. Replaces H2O and electrolytes. If in doubt, use Hartmanns. Watch for overload. Ephedrine should be used if hypotension persists. Dextrose 5% isotonic Rarely used Increases maternal blood sugar - increases fetal insulin - fetal hypoglycaemia - jaundice. Haemaccel Synthetic polygeline colloid Plasma volume expander Not so commonly used as was. Whole blood Plasma volume replacement, replaces red blood cells (hb), replaces clotting factors, source of fresh blood. Increases O2-carrying capacity, administer through blood filter, do not infuse cold, risk of blood borne infections. Packed cells Treat anaemia, used with women with low hb but adequate blood volume. Increases O2-carrying capacity, replaces low hb without extra plasma volume preventing overload, administer through blood filter, risk of blood borne infections.
