Criteria used to identify and classify cases of near-miss Waterstone's criteria (11) * Severe pre-eclampsia * Eclampsia * HELLP syndrome (haemolysis, elevated liver enzymes, low platelets) * Severe haemorrhage * Severe sepsis * Uterine rupture Mantel's criteria (12) * Admission to an intensive care unit for whatever reasons * Hypovolaemia
requiring five or more units of packed red blood cells * Pulmonary oedema * Emergency hysterectomy for any reason * Admission to an intensive care unit for sepsis * Intubation and ventilation for more than 60 minutes except for general anaesthesia * Diabetic ketoacidosis * Coma for more than 12 hours * Cardio-respiratory arrest * Peripheral [O.
The effect of moderate hypovolaemia
on microcirculation in healthy older blood donors.
They will explain that one of the major causes of slow post-operative recovery is reduced circulating blood volume - hypovolaemia
Volplex is given as an intravenous infusion to substitute for blood volume lost by patients suffering from the effects of trauma, surgery or certain medical conditions which result in hypovolaemia
(lower than normal blood volume).
There is another issue touched on by Beaumont Hospital's anaesthesia consultant Michael Power, who states that excesive dehydration can result in serious head injury when a jockey has a fall because it causes a condition called hypovolaemia
6] This is surely reinforced by the findings of the NCCEMD that the following major causes of the 2011-2013 deaths from hypovolaemia
ascribed to haemorrhage were:
Infection of the adrenal cortex causes disruption of steroid synthesis and contributes to profound hypotension, loss of sodium and hypovolaemia
experienced in the later stages of EVD.
The pathophysiology of shock and multi-organ failure in burns is complex, mediated initially by direct thermal tissue injury and hypovolaemia
, and subsequently dominated by severe immune and cytokine-mediated systemic inflammatory response syndrome (SIRS).
Extravasations of plasma may cause hypovolaemia
, which may lead to hypovolaemic shock, especially in children.
6H refers to hypoxia, hypovolaemia
, hydrogen ions (acidosis), hyper- and hypokalaemia, hypothermia, and hypoglycaemia,
Virtually every patient undergoing surgery suffers from hypovolaemia
, similar to dehydration, due to the combined effects of pre-operative starvation, the impact of anaesthetic gases, and the trauma from surgery itself.
Volplex (succinylated gelatin) is given as an intravenous infusion to substitute for blood volume lost by patients suffering from the effects of trauma, surgery or certain medical conditions which result in hypovolaemia
(lower than normal blood volume).
Poor recognition of the severity of the blood loss causing hypovolaemia
In these situations, a fine balance must be held between hypovolaemia
and fluid overload, both of which may carry severe consequences for an already compromised individual.
