Infectiological diagnostic problems in tertiary peritonitis
Tóm tắt
The tertiary peritonitis causes the highest mortality in intraabdominal infections. Surgical interventions and antibiotic therapy may only provide an incomplete impact on nosocomial infections acquired at an intensive care unit (ICU) [Nathens et al., World J Surg 22:158–163, 28]. To open up new resources in the management, in particular, in the previous infectious diagnostic, the aim was to investigate the infectious course as well as the diagnostic value of laboratory parameters and microbiological monitoring. In this retrospective patient cohort study from the Surgical ICU of a University Hospital (capacity, n=12), overall, 60 patients with a tertiary peritonitis were enrolled. Approximately 20% of the patients with an intraabdominal infection developed a tertiary peritonitis. A tertiary peritonitis can more frequently develop in nosocomial intraabdominal infections, in particular, in case of necrotizing pancreatitis. The device-associated infection rate in the spectrum of nosocomial infections is sevenfold higher than in all ICU patients. Compared with the secondary peritonitis, its mortality is double as high: 35%. In the diagnostic characterizing the course of the nosocomial, prognosis-relevant infections, usual inflammatory parameters show a considerable loss of their sensitivity with a range from 35–57%. By the mean of a routine microbiological monitoring, 47.3% of the analysed subsequent infections could be identified at an early stage. In patients with a severe infection, an early diagnostic and treatment of infectious “second hits” can improve the complication rate and prognosis. During the prolonged and complicated septic course of tertiary peritonitis, an additional routine microbiological monitoring contributed effectively to early detection and diagnostic of nosocomial infections. Further studies to investigate the value and efficacy of such monitoring, which have been abandoned, should be undertaken in infectious high-risk patients.
