Prognostic factors in patients with septic shock in digestive surgery who have undergone direct hemoperfusion with polymyxin B-immobilized fibers: a retrospective observational study.


ABSTRACT: BACKGROUND:Direct hemoperfusion with polymyxin B-immobilized fiber (PMX-DHP) has been widely used for patients with septic shock around the world, but the prognostic factors have not been fully understood. We conducted a retrospective analysis to determine the prognostic factors in patients with septic shock who underwent PMX-DHP. METHODS:Twenty-nine patients with septic shock who underwent PMX-DHP were included in the study. The patients were divided into groups based on survival (n?=?23) and non-survival (n?=?6) 28 days after PMX-DHP, and the clinical data for the two groups before and after PMX-DHP were compared. RESULTS:In non-survivors, the vasopressor dependency index before PMX-DHP was significantly higher (p?=?0.046), and the leukocyte count before PMX-DHP was significantly lower (p?=?0.024) than in survivors. Furthermore, base excess after PMX-DHP was significantly lower in non-survivors (p?=?0.007) than in survivors. The optimal cutoff points of the vasopressor dependency index, leukocyte count, and base excess identified by receiver operating characteristic curves were 0.499/mmHg, 1360/?L, and -6.4 mmol/L, respectively. And the score using these three cutoffs, termed the prognostic score, was related to the prognosis of septic shock patients who underwent PMX-DHP (area under the curve?=?0.946). CONCLUSIONS:The prognostic score, using three parameters which are immediately and readily available in early phase after starting PMX-DHP, might be useful to predict the prognosis of these patients.
