Alternative Meds, Surgery Don't Mix

Using alternative health care products within two weeks of surgery can set you up for some unpleasant side effects, the American Association of Nurse Anesthetists says. The association's study, in the AANA Journal, evaluates interaction of anesthetics with vitamins, herbs, dietary supplements and homeopathic medicines.

Some alternative medicines, the study says, increase bleeding and prolong coagulation during surgery. These include alfalfa, chamomile, some Chinese herbs, garlic, ginko, kava, licorice, vitamin E and fish oil.

Other reported risks for surgical patients:

--Black cohosh -- used to treat menopause, menstrual cramps and osteoporosis -- can lower blood pressure.

--St. John's wort, used for depression, can raise blood pressure and cause confusion, agitation and drowsiness.

--Ephedra, an herb used for coughing, asthma and weight loss, can lead to arrhythmia and high blood pressure.

--Licorice, used for coughing and sore throats, can raise the risk of hypokalemia, a potassium deficiency that can cause arrhythmia.

--Herbal diuretics, which increase urine output, can deplete potassium levels and cause electrolyte imbalances.

--Sedative herbs, such as kava, can cause severe drowsiness when combined with the hypnotic drugs used during surgery.
