Abstract: We investigated the role played by lactate and H+ in evoking the exercise pressor reflex in decerebrated rats whose hindlimb muscles were either freely perfused or ischemic. Production of lactate and H+ by the contracting… read more here.

DOI: 10.1177/8755122519846164
Abstract: Background: Pressor agents are recognized as high-alert medications by the Institute for Safe Medication Practices, but little evidence is available to guide their use in septic shock. Objective: Characterize the use of pressor agents for… read more here.
