Why the study?
Does 2 litres of crystalloid compared to 1 litre of colloid solution prevent hypotension in mothers undergoing elective Caesarean section under epidural anaesthesia?
Does 2 litres of crystalloid compared to 1 litre of colloid solution prevent hypotension in mothers undergoing elective Caesarean section under epidural anaesthesia?
Crystalloid and colloid solutions appear to have similar effects on hemodynamics and fetal parameters when used for circulatory preload prior to elective Caesarean section under epidural anaesthesia.
Either crystalloid or colloid preload may be used; confirms equivalence for maternal hemodynamics and fetal outcomes in elective caesarean under epidural.
Sixty mothers were randomly allocated to receive either 2 litres of crystalloid or 1 litre of colloid solution (hydroxyethyl starch) in order to preload the circulation prior to elective Caesarean section under epidural anaesthesia. There were no differences in the incidence of hypotension, degree of haemodilution, umbilical cord blood gas tensions or umbilical blood osmolalities between the two groups.
