Clemastine in Cardiovascular Surgery

Study Purpose

In this study, a prospective, randomized, double-blind pilot trial designed to evaluate the effect of histamine H1 receptor antagonist clemastine on perioperative anaphylaxis in cardiovascular surgery with cardiopulmonary bypass, especially for the efficacy and safety on reducing heparin and protamine associated anaphylaxis.

Recruitment Criteria

Accepts Healthy Volunteers
