“…They were then asked to estimate the degree of tilt they had applied and the actual tilt was measured using the iHandy Level© iPhone app. As in a prior study , my study reiterated that the perceived tilt applied to the operating tilt was grossly overestimated. Interestingly, in our study the degree of overestimation was greatest amongst obstetricians compared with anaesthetists, with a median (IQR) error of 14° (10°–25°) compared with 12° (5°–22°), respectively.…”

“…We used two wedges that were designed for this purpose to ensure accurate angle estimation. It had been previously reported that over-estimation of tilting angle is common among obstetric anesthetists [ 13 ].…”

Hemodynamic effects of lateral tilt before and after spinal anesthesia during cesarean delivery: an observational study

et al. 2018

BackgroundPost-spinal hypotension is a common maternal complication during cesarean delivery. Aortocaval compression by the gravid uterus has been assumed as a precipitating factor for post-spinal hypotension. The role of left lateral tilting position in improving maternal cardiac output after subarachnoid block (SAB) is unclear. The aim of this work is to investigate the effect of left lateral tilting on maternal hemodynamics after SAB.MethodsA prospective observational study was conducted including 105 full term pregnant women scheduled for cesarean delivery. Mean arterial pressure, heart rate, cardiac output (measured by electrical cardiometry), stroke volume, and systemic vascular resistance were recorded in three positions (supine, 150, and 300 left lateral positions) before SAB, after SAB, and after delivery of the fetus.ResultsBefore SAB, no significant hemodynamic changes were reported with left lateral tilting. A significant decrease was reported in mean arterial pressure, cardiac output, stroke volume, and systemic vascular resistance after SAB (in supine position). When performing left lateral tilting, there was an increase in cardiac output, heart rate, and mean arterial pressure. No difference was reported between the two tilt angles (150 and 300).ConclusionsChanging position of full term pregnant woman after SAB from supine to left lateral tilted position results increased cardiac output and mean arterial pressure. There is no difference between the two tilt angles (150 and 300).Trial registrationclinicaltrials.gov (NCT02828176) retrospectively registered.

“…Once the woman is positioned supine for surgery, left uterine displacement is routinely used to reduce inferior vena cava compression, with a recommended angle of 15° . This angle of table tilt is associated with higher maternal SAP and cardiac output and lower doses of infused phenylephrine than the unmodified supine position , but is seldom achieved in practice . If the table is tilted to 15°, lateral support is required for security.…”

International consensus statement on the management of hypotension with vasopressors during caesarean section under spinal anaesthesia

et al. 2017

Why was this consensus statement developed?Advances in clinical practice are sometimes inhibited by a multitude of different options that need to be selected. There has been significant variation in the treatment of spinal anaesthesia-induced hypotension. These guidelines are designed to provide clinicians with specific best-practice plans that will cover a wide range of drug and equipment availability. Detailed recommendations are provided for the management of hypotension in resource-rich and resource-poor environments.
