Is a relatively high pre-spinal heart rate associated with reduced efficacy of prophylactic vasopressor during spinal anaesthesia for caesarean section?

      There is evidence from studies of heart rate variability that relatively high levels of sympathetic activity before spinal anaesthesia are associated with lower minimum absolute values for systolic arterial pressure (SAP) during spinal anaesthesia for caesarean section.

      Two studies have also observed that a relatively high pre-spinal heart rate is associated with lower minimum values for SAP, expressed as a proportion of baseline, during spinal anaesthesia.

      A prophylactic vasopressor was not used in these studies. We have re-examined data from a previous study of women undergoing spinal anaesthesia for caesarean section,

      to assess whether differences in pre-spinal heart rate are associated with differences in the minimum value for SAP when a prophylactic vasopressor is given.
