The purpose of this study was to determine if any interval between preoperative or postoperative administration of doxorubicin hydrochloride (Adriamycin) and wounding would limit the impairment in healing induced by Adriamycin. The question was evaluated in 7 cm incisional wounds on the dorsal midline of rats. Preoperative Adriamycin was administered 42, 28, 21, 14, and 7 days before wounding, and wound breaking strengths (WBS) of the incisional wounds were measured 7, 18, and 28 days after wounding. Postoperative Adriamycin was administered 0, 7, 14, 21, and 28 days after wounding, and WBS were measured 7, 14, 28, 35, and 42 days after wounding. A similar and significant degree of impairment was induced in healing by all preoperative Adriamycin regimens evaluated. Postoperative Adriamycin administered up to 21 days after wounding induced a healing deficit that manifested 1 to 2 weeks after Adriamycin administration. Adriamycin administered 28 days after surgery induced no demonstrable impairment in WBS. In addition, Adriamycin never decreased the WBS of a wound after a certain degree of strength had been obtained. These results lead us to warn against the use of preoperative Adriamycin and support the use of postoperative Adriamycin administered 28 days after a surgical procedure.
