Randomized Controlled Trial Comparative StudyComparison of the potency of phenylephrine and norepinephrine bolus doses used to treat post-spinal hypotension during elective caesarean section.
Phenylephrine, although considered the vasopressor of choice, can cause reflex bradycardia and a fall in cardiac output. Norepinephrine, due to its direct positive chronotropic and reflex negative chronotropic actions, is expected to overcome this problem. However, limited information about its effective dose for management of post-spinal hypotension, and its potency compared to phenylephrine, is available. ⋯ Based on the results of this study, norepinephrine is about 11 times more potent than phenylephrine. When used as bolus doses for treatment of hypotension, 100 μg phenylephrine should be approximately equivalent to 9 μg norepinephrine.

Case ReportsHow low did we go? A case report of unexpected thrombocytopenia.
We report the case of a normotensive 31-year-old parturient who received combined spinal-epidural analgesia for early labor, and who was then found to have an unexpectedly low platelet count (25 000/μL) with elevated liver enzymes, but without alterations in blood pressure.
