However, the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery, but commonly used in other areas. During this shortage we have trialed topical nitroglycerin to break intraoperative vasospasm. This study aims to analyze the outcomes of this medication on flap complications compared with papaverine.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>All consecutive free flaps performed for breast reconstruction at a single institution were reviewed. Data collected included patient demographics, co\u2010morbidities, complications and type of antispasmodic agent.

Patients treated with nitroglycerin tended to have higher BMI (32.1 vs. 27.9, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01), higher rates of pre\u2010operative chemotherapy (83.3% vs. 51.3%, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01) and shorter follow\u2010up duration (735 vs. 1691 days, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01). However, no differences in complications were observed, including: unplanned return to the operating room, flap loss, fat necrosis, infection, hematoma, or seroma.
