Background: Subarachnoid blockade for cesarean section still poses a threat of profound hypotension and can result in unstable maternal and fetal hemodynamics. The correlation of fetal breech and vertex presentation with the occurrence of hypotension under spinal anesthesia is reviewed in this retrospective, double-blind study.
Patients and methods: The study was conducted on pregnant females scheduled for a lower segment cesarean section between January 2014 and December 2014. After applying inclusion criteria, 568 patients were recruited in the study out of which 363 had vertex and 184 patients had breech presentation. They were divided into two groups, Group I and Group II. The monitoring and therapeutic data (blood pressure, heart rate, arterial oxygen saturation, and dose of vasopressor/atropine) recovered from automated data analysis were analyzed retrospectively for prevalence of hypotension, bradycardia, and hypotension with bradycardia and nausea ± vomiting.
Results: Among Group I, prevalence of hypotension, bradycardia, and hypotension together with bradycardia was 152 (41.83%) patients, eight (2.20%) patients, and seven (1.92%) patients, respectively. In Group II, the prevalence of hypotension, bradycardia, and hypotension with bradycardia was 93 (50.5%) patients, five (2.71%) patients, and six (3.2%) patients, respectively. The difference between the two groups was statistically significant for hypotension. For Group I, 152 patients (41.87%) experienced one, 23 patients (6.33%) experienced two, and three patients (0.82%) experienced three episodes of hypotension. In Group II, 93 (50.5%), 19 (7.89%), and two (1.08%) patients experienced such episodes. The difference was significant with respect of one and two episodes. The prevalence of intraoperative nausea was 11.01% (40 patients) in Group I, whereas 11.41% (21 patients) in Group II. Intraoperative vomiting occurred in 19 patients (5.23%) of Group I and 14 patients (7.60%) of Group II. The height of the block was comparable in both the groups for T6, and the difference was significant in respect to T4 level.
Conclusion: Incidence of hypotension is more in pregnant females with breech fetal presentation.
