To answer the questions if intra-abdominal hypertension (IAH) influences\r\nsuture tension in midline laparotomies and if IAH leads to a permanent loss of\r\nsuture tension, microsensors were applied in a porcine model of IAH.\r\nMaterial and methods: Microsensors measuring suture tension “on the thread” with a frequency\r\nof 1/s were developed and implanted in the suture lines of midline laparotomies in\r\nfour pigs. During a 23-h experiment under general anesthesia, two intervals of IAH (30 mm\r\nHg) were applied, interrupted by a 3-h interval without elevated intra-abdominal pressure.\r\nResults: All sensors showed an immediate and reproducible response to changes of intraabdominal\r\npressure. The two 9-h periods of IAH resulted in a significant elevation of suture\r\ntension (P¼0.003 and P¼0.0009, respectively). Reducing the IAH lead to a significant loss\r\nof suture tension (P¼0.0005andP¼0.0001, respectively). After the second interval with IAH, a\r\ncomplete loss of mean suture tension was observed. A statistically significant “recovery” of\r\nsuture tension in the interval between the two phases with IAH was not observed.\r\nConclusions: Intervals with elevated intra-abdominal pressure have a direct influence on\r\nsuture tension in midline laparotomy wounds. Intervals with IAH lead to a significant loss\r\nof suture tension in the suture line and to a complete loss of mean suture tension at the\r\nend of this experiment. A subsequent gaping of the fascia might contribute to either acute\r\nor chronic failure of laparotomy closure"}],"publication_identifier":{"issn":["00224804"]},"page":"207-212","date_updated":"2023-08-18T11:54:15Z","intvolume":"       233","language":[{"iso":"eng"}],"publication_status":"published","year":"2019","title":"Influence of Elevated Intra-abdominal Pressure on Suture Tension Dynamics in a Porcine Model","date_created":"2023-06-15T13:02:39Z","publication":"Journal of Surgical Research","citation":{"alphadin":"<span style=\"font-variant:small-caps;\">Schachtrupp, Alexander</span> ; <span style=\"font-variant:small-caps;\">Wetter, Oliver Utz</span> ; <span style=\"font-variant:small-caps;\">Höer, Jörg</span>: Influence of Elevated Intra-abdominal Pressure on Suture Tension Dynamics in a Porcine Model.
