The effect of spinal analgesia on the hemodynamic indices in cesarean section

We studied systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse frequency (P.F) and mean blood pressure (MBP) among 30 pregnant women in 39.5 +/- 0.3 gestational weeks of pregnancy, age 23 +/- 0.9 years, height 162.0 +/- 1.4 cm and weight 75.5 +/- 2.55 kg. The above indices were studied dynamically in the Ist, 2nd, 3rd, 5th, 7th, 9th, 12th and 15th minute from the onset of the analgesia. We founded that SBP an DBP in the 7th min (the time for spinal block) were lowest. PF and MBP also decreased significantly in the 7th minute in comparison to the inmal values. We can conclude that the haemodynamic indices of the pregnant woman decrease wrong initiation of spinal analgesia for c.s., but remain in the region of normal reference values.
