Nearly all women who deliver babies through cesarean section at Columbia University Irving Medical Center in New York City receive injections of the blood thinner heparin for weeks after the procedure, to prevent potentially life-threatening blood clots.
Broad use of heparin has been shown to be effective and safe in the United Kingdom in reducing that risk and should be adopted in the U. Last year, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine recommended heparin only for women at elevated risk of VTE, citing a lack of evidence supporting near-universal use.
The controversy illustrates a classic dilemma for physicians: whether and how to adopt promising new treatments before studies have proven their safety and effectiveness. There also are questions about keeping drug company funding from influencing clinical recommendations around the drug. The Columbia doctors were lead authors how to draw high school musical guidelines from the National Partnership for Maternal Safety Ч a multidisciplinary group of medical experts Ч encouraging doctors to give heparin shots to all women after C-sections, except patients with specific risks.

A study found that out ofwomen who delivered through C-section and received the standard nondrug therapy of pneumatic compression devices applied to the legs to reduce clotting risk, just one woman died from pulmonary embolism.
The cost of preventing that one death? Rouse and other critics say there have been no solid studies either of how effective heparin is how to improve dj skills preventing clots or of how many women suffer adverse effects from heparin such as hemorrhage or problems in wound healing. Meanwhile, Canadian researchers are planning to test an alternative drug that may be equally effective, safer and cheaper in preventing VTE in women after delivery Ч aspirin.
