Associated factors with umbilical arterial pH after cesarean delivery under spinal anesthesia: a retrospective cohort study.

Background: Maximum decrease of blood pressure and number of minutes of hypotension were independently associated with umbilical arterial pH. However, the impact of hypotension considering the duration of it on umbilical arterial pH is unknown.

Methods: Pregnant women aged ≥ 20 years who delivered a baby at full-term via a cesarean delivery under a single-shot spinal anesthesia between January 2017 and March 2019 were included.

[Clipping of a Large Unruptured Basilar Artery Trunk Large Aneurysm Using Rapid Ventricular Pacing:A Case Report].

Neck clipping of basilar trunk aneurysms, particularly those of a large size, is challenging because of its location. Here, we report a case of a basilar artery aneurysm successfully treated with neck clipping using rapid ventricular pacing(RVP). A 67-year-old woman was referred to our hospital for treatment of a large basilar artery aneurysm.
