Hasanin A, et al. - Aortocaval compression by the gravid uterus has been assumed as a precipitating factor for post-spinal hypotension, which is known as a common maternal complication during cesarean delivery. In this study, researchers determined the impact of left lateral tilting on maternal hemodynamics after subarachnoid block (SAB). They observed increased cardiac output and mean arterial pressure resulting from changing position of full-term pregnant woman after SAB from supine to left lateral tilted position. In addition, they observed no difference between the two tilt angles (150 and 300).
