Doses of intrathecal bupivacaine based on patients either height or height and weight has
shown to lower the risk of maternal hypotension with similar quality of anesthesia compared
to conventional doses.

In clinical practice there is a tendency of reducing the dose of bupivacaine as either low
fixed dose or using the doses based on either height and weight or height (0.06mg/cm) alone
in parturient with short stature. However, there is lack of evidence regarding the
appropriate dose required in this group of patients. Therefore, our aim is to compare the
height versus height and weight based intrathecal bupivacaine dose for elective caesarean on
maternal haemodynamics in short stature patients.
