“…Recently developed noninvasive devices used to measure BP and monitor maternal hemodynamic variables such as cardiac index. Despite limited data, these noninvasive devices have shown potential for tracking responses to spinal anesthesia-induced sympathetic blockade and vasopressor administration without the need for invasive procedures in cesarean section [25][26][27]. For example, ClearSight™ (Edwards Lifesciences), a noninvasive continuous BP monitoring device using a finger cuff, has demonstrated acceptable accuracy and precision compared to that in invasive monitoring methods [28].…”

Cesarean sections are commonly performed under spinal anesthesia, which can lead to hypotension, adversely affecting maternal and fetal outcomes. Hypotension following spinal anesthesia is generally defined as a blood pressure of 80–90% below the baseline value. Various strategies have been implemented to reduce the incidence of spinal anesthesia-induced hypotension. The administration of vasopressors is a crucial method for preventing and treating hypotension. In the past decade, phenylephrine, a primarily alpha-adrenergic agonist, has been the preferred vasopressor for cesarean sections. Recently, norepinephrine, a potent alpha-agonist with modest beta-agonist activity, has gained popularity owing to its advantages over phenylephrine. Vasopressors can be administered via a bolus or continuous infusion. Although administering boluses alone is simpler in a clinical setting, continuous prophylactic infusion initiated immediately after spinal anesthesia is more effective in reducing the incidence of hypotension. Tailoring the infusion dose based on the patient’s body weight and adjusting the rate in response to blood pressure changes, in addition to using a prophylactic or rescue bolus, helps reduce blood pressure variability during cesarean sections under spinal anesthesia until neonatal delivery.
