The gravid uterus begins to compress the IVC in the supine position beginning at approximately the 20th week of pregnancy, with obstruction becoming virtually complete at term. Blood returns from the lower extremities through the collaterals which are developed during pregnancy, few examples are intraosseous, vertebral, paravertebral, and epidural veins. A prospective, randomized controlled study was done after obtaining the approval of institutional Ethics committee to compare the hemodynamic changes during lateral table tilt and supine position in women undergoing Caesarean section, in the Department of Anesthesiology. A total of 140 patients were enrolled for the study with the following inclusion and exclusion criteria. Mean time taken after spinal anesthesia to cause maximum fall in blood pressure before extraction in subjects in both group-L and group-S is 3.94±1.52 and 4.11±1.46 respectively. There was no statistically significant difference between the groups with a p value of .498and 95% confidence interval of -0.670 to 0.327.
