DICP : the annals of pharmacotherapy

A 75-year-old man with hyperdynamic septic shock and vasodilation was successfully supported hemodynamically for 88.5 hours through the use of a continuous infusion of phenylephrine at dosages up to 360 micrograms/min. The only other vasoactive compound administered was dopamine at a dosage of 3.4 micrograms/kg/min. ⋯ Phenylephrine's pharmacologic properties may represent an advantage for its use as a vasoconstrictor over catecholamines such as norepinephrine and dopamine, particularly in patients who develop tachyarrhythmias with these agents. The pharmacology, dosage, and appropriate monitoring of therapy with phenylephrine in patients with septic shock are discussed.

Among the many advances made in intensive care therapeutics in recent years, few have rivaled the impact of mechanical ventilators. Their expanded use affects all who practice in the critical care setting. ⋯ A basic introduction is made into ventilator set up, weaning techniques, adjunctive drug therapy, and complications. The pharmacotherapy specialist who understands interactions between patients and ventilators, and the effects of mechanical ventilation on cardiopulmonary function will be best equipped to individualize drug therapy.

Improper inhalation technique with beta-agonist metered-dose inhalers (MDIs) decreases efficacy of the bronchodilator. The success of demonstrating the correct technique and the pharmacist's role in patient education has been reported. To obtain information regarding the routine patient education practice of pharmacists when dispensing a beta-agonist MDI (albuterol), the following study was performed. ⋯ No pharmacist asked the PI to perform the technique while he/she observed. No pharmacist offered information on delivery enhancement devices. Our results demonstrate that few pharmacists educate patients on the correct usage of an MDI, and that many pharmacists are not aware of the correct technique.
