Abstract

Sectio caesarea with spinal anesthesia is the act of giving birth by opening the uterine wall to expel the fetus, this is done for pregnant women with certain conditions that are very risky if a normal delivery is carried out. Spinal anesthesia itself has several complications, one of which is hypotension. From many studies, BMI is one of the factors causing post-spinal anesthesia hypotension. The purpose of this study was to determine the relationship between late pregnancy BMI and the incidence of post-spinal anesthesia hypotension in caesarean section in the operating room of Bangil Hospital. The research design used in this study is a correlational analytic design, with a cross-sectional approach. The population was all maternity patients who underwent sectio caesaria surgery with spinal anesthesia in June, totaling 88 patients who were taken using consecutive sampling. Data was taken using questionnaires and weight scales and height gauges. After the data was collected, data processing was carried out and continued with the Wilcoxon test statistic with the probability result Asymp.Sign = 0.000, so that H0 was rejected and Ha was accepted, which means that there is a relationship between BMI late in pregnancy and the incidence of post-spinal anesthesia hypotension in sectio caesaria in the operating room at Bangil Hospital. BMI of pregnant women is caused by hormonal changes during pregnancy, one of which is an increase in fluid in the body causing sodium to increase in the final trimester of pregnancy. Spinal anesthetic drugs work by inhibiting the entry of sodium into nerve cells, thus preventing nerve depolarization resulting in venous vasodilation and hypotension occurs.
