Group I consisted of patients whose NPWT was successful (n\u2009=\u2009117\/198; 59.1%), while in Group II treatment, failure occurred (n\u2009=\u200981\/198; 40.9%).

During the study period, 10\/198 (19.8%) patients died after secondary wound healing. In group I, 1\/117 (0.9%) patient died versus group II with 9\/81 (12.7%) patients. About 70% patients died from septic multiple organ failure.<\/jats:p>\n                  <jats:p>This study confirms that variables associated with treatment failure after NPWT in PSM are BMI &gt;30\u2009kg\/m2, diabetes mellitus (DM), and the \u201cnumber of sponge changes,\u201d respectively. However, this does not mean that sponge changes increase the risk; rather, sponge changes are associated with more resistant germs, incomplete wound healing, and more aggressive infection. This implies that management should be in the hands of cardiac surgeons with extensive experience in septic surgery and at centers with expertise in order to minimize the duration of NPWT and thus the number of sponge changes.<\/jats:p>","DOI":"10.1055\/a-2733-4361","type":"journal-article","created":{"date-parts":[[2025,10,31]],"date-time":"2025-10-31T00:21:51Z","timestamp":1761870111000},"page":"404-409","source":"Crossref","is-referenced-by-count":0,"title":["Variables
