Changes in haemodynamic parameters for the control; hypovolaemia and endotoxaemia rabbits.

<p>The central bar is the mean, the box represents the inter-quartile range and the whiskers the range. Significant differences between the control and experimental groups of p<0.05 are noted by an ‘*’ and p<0.01 by an ‘¤’.</p

Changes in biochemistry, catecholamines and haematocrit in the endotoxin group.

<p>Interquartile ranges [IQR] and standard deviations are shown (SD) according to the distribution of the variables.</p>*<p>p<0.05,</p>¤<p>p<0.01.</p

Gant chart showing schema of blood sampling and electrical stimulation.

<p>Control rabbits and the experimental groups all received the same number of stimulations and blood samples. Endotoxaemic rabbits had five stimulations and three blood samples that were not analysed, as according to protocol, so as to ensure identical experimental conditions for all groups.</p

Changes in biochemistry, catecholamines and haematocrit in the hypovolaemic rabbits.

<p>Interquartile ranges [IQR] and standard deviations are shown (SD) according to the distribution of the variables.</p>*<p>p<0.05,</p>¤<p>p<0.01.</p
