Abstract：
:Vasopressin is now commonly used to control bleeding during surgery of the cervix. In larger intravenous doses, vasopressin can cause coronary artery vasoconstriction and increase systemic vascular resistance. Nicotine has a similar effect on the coronary circulation. The effects of combining both these drugs has not been studied. We describe a 22-year-old woman who developed severe hypotension and bradycardia after receiving a small dose of paracervical vasopressin. She was using a transdermal nicotine patch at the time of her surgery. We suspect her cardiac problems, and recently reported cardiac events in other women receiving small doses of paracervical vasopressin, could be caused by a synergism of the vasoconstrictive properties of nicotine and vasopressin. Caution is urged when vasopressin is to be administered to patients who smoke or use nicotine transdermal patches.
