An Observational Study of Proportion and Risk Factors of Hypotension in Parturients Undergoing Spinal Anaesthesia for Caesarean Section
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 7
Abstract
Background: Spinal Anaesthesia (SA) is the most common preferred anaesthesia technique for Caesarean section (CS), because of its superior analgesia, favourable relaxation and decreased risk of complications over general anaesthesia1,2,3,4. Incidence of hypotension after spinal anaesthesia is highest in Caesarean section, and it can be significantly severe so that it can jeopardize the mother and foetus5,6,7,8,9,10,11,12,13. So early detection and prevention of hypotension is of atmost importance for better maternal and foetal outcome. This study aim to assess the incidence of spinal anaesthesia induced hypotension in parturients and confirm the existing risk factors and also to identify new risk factors if any in a population, where published studies are nil. Methods: After obtaining approval from Research committee and institutional ethical committee a total of 200 patients who satisfied the inclusion and exclusion criteria were included in the study and evaluated for the development of hypotension after spinal anaesthesia. The population was divided in to two groups with and without hypotension after spinal anaesthesia for Lower segment caesarean section (LSCS). The two groups were then compared with respect to their demographic, maternal, anaesthetic and foetal variables to see whether any association exist with the development of maternal hypotension. Results: In the present study the proportion of hypotension following spinal anaesthesia for CS was 54.5% (109/200). Univariate analysis identified 3 maternal risk factors such as age>30 years, ASA class II, and BMI>30kg /m2 . Anaesthesia related variable identified was sensory block height ≥ T5.Neonatal birth weight >2.5.kg was found as the significant foetal variable. Conclusion: The incidence of maternal hypotension in the parturient after SA still remains high. Knowledge of the incidence and risk factors as well as timely intervention will definitely contribute to early detection and prevention of severity maternal hypotension.
