The Various Effects of Gaseous Albuterol on Serum Lactate

Approximately 30 healthy volunteers will be randomized to Albuterol or placebo. We powered our study to detect a difference of 0.5 mmol/L, but hypothesize that the difference will be greater than 1.0 mmol/L.

All volunteer subjects will sign a written consent, approved by the Institutional Review Board. The intended pool of volunteers will be from residents, attendings, and medical students in the hospital. The consent form will clearly specify that their participation in the study will not impact their academic status or employment.

The subjects randomized to the Albuterol arm will receive a one hour 10 mg continuous Albuterol nebulizer treatment. Those randomized to placebo will receive a one-hour saline nebulizer treatment. The chief pharmacist for the study will randomly assign a number between one and thirty to fifteen Albuterol treatments and fifteen placebo treatments.

Subjects will be monitored with cardiac monitor and serum lactate levels will be drawn every 15 minutes.
