Hypertension is the most prevalent cardiovascular disease worldwide, but its genetic basis is poorly understood. Recently, genome-wide association studies identified 33 genetic loci that are associated with blood pressure. However, it has been difficult to determine whether these loci are causative owing to the lack of functional analyses. Of these ...

An anesthesiologist must remain vigilant of the patient's clinical status, incorporating many independent physiological measurements. Oxygen saturation and heart rate are represented by continuous audible tones generated by the pulse oximeter, a mandated monitoring device. Other important clinical parameters-notably blood pressure-lack any audible representation beyond arbitrarily-configured threshold alarms. Attempts to ...

Prophylactic fluid preloading before spinal anesthesia has been a routine procedure to prevent maternal hypotension during cesarean delivery. Unlike colloid, timing of infusion of crystalloid may be important because of its short stay in intravascular space. We hypothesized that crystalloid loading just after intrathecal injection compared to preload would be ...
