Endotoxin, a component of the cell membrane of gram-negative bacteria, is a trigger for dysregulated inflammatory response in sepsis. Extracorporeal purification of endotoxin, through adsorption with polymyxin B, has been studied as a therapeutic option for sepsis. Previous studies suggest that it could be effective in patients with high endotoxin levels or patients with septic shock of moderate severity. Here, we perform a retrospective, single-centre cohort study of 93 patients suffering from abdominal septic shock treated with polymyxin-B hemoperfusion (PMX-HP) between 2015 and 2020. We compared deceased and surviving patients one month after the intervention using X² and Mann-Whitney U tests. We assessed the data before and after PMX-HP with a Wilcoxon single-rank test and a multivariate logistic regression analysis. There was a significant reduction of SOFA score in the survivors. The expected mortality using APACHE-II was 59.62%, whereas in our sample, the rate was 40.9%. We found significant differences between expected mortality and real mortality only for the group of patients with an SOFA score between 8 and 13. In conclusion, in patients with abdominal septic shock, the addition of PMX-HP to the standard therapy resulted in lower mortality than expected in the subgroup of patients with intermediate severity of illness.

Background: Esophagectomy is associated with substantial postoperative morbidity, with infectious complications remaining a leading cause of mortality. Septic shock represents the most severe infectious complication; however, data on its perioperative predictors and long-term impact after esophagectomy are limited. Methods: We conducted a retrospective observational study including consecutive adult patients who underwent esophagectomy with curative intent for esophageal cancer between January 2015 and December 2024 at a tertiary referral center. Postoperative septic shock was defined according to Sepsis-3 criteria. Demographic, clinical, surgical, laboratory, and oncological variables were analyzed. Independent risk factors for septic shock were identified using multivariate logistic regression. Overall survival was assessed using Kaplan–Meier analysis. Results: Among 106 patients, 19 (17.9%) developed postoperative septic shock. These patients had a lower body mass index, reduced preoperative and postoperative albumin levels, and a higher incidence of advanced lymph node involvement. Septic shock was strongly associated with severe postoperative complications, including anastomotic leakage, hemorrhagic shock, acute respiratory distress syndrome, acute kidney failure, and increased rates of PICU readmission. In multivariate analysis, lower albumin levels at PICU admission (OR 0.54; 95% CI 0.29–0.99) and advanced nodal stage (OR 4.98; 95% CI 1.36–18.3) were independently associated with the development of septic shock. Patients who developed septic shock had significantly higher in-hospital mortality (31.6% vs. 1.1%, p < 0.001) and markedly reduced long-term survival, even among those discharged alive. Conclusions: Postoperative septic shock after esophagectomy is a devastating complication with a profound negative impact on both short- and long-term survival. Hypoalbuminemia and advanced lymph node involvement are independent predictors of septic shock. These findings support the integration of simple clinical and laboratory markers into personalized perioperative risk stratification models, enabling individualized management strategies to reduce severe postoperative complications.

Background/Objectives: Unplanned readmission to the surgical intensive care unit (UR-SICU) is a serious adverse event linked to higher morbidity, prolonged stay, and increased mortality. Most evidence derives from mixed ICUs, limiting applicability to surgical cohorts. We aimed to identify risk factors for UR-SICU and assess their impact on outcomes. Methods: We performed a retrospective cohort study of adults admitted to a 20-bed SICU in a tertiary hospital between June 2021 and December 2022 after non-cardiac surgery (elective, urgent, trauma, or liver transplantation). Patients dying during the first SICU stay or transferred to another ICU were excluded. Demographics, comorbidities, severity scores, treatments, and complications were recorded. Logistic regression identified predictors. Kaplan–Meier curves analyzed survival. Results: Among 1361 patients, 82 (6.4%) required UR-SICU. Half were surgical (mainly hemorrhage and sepsis), while respiratory and infectious complications predominated among medical readmissions. Independent predictors for UR-SICU were age (OR 1.03/year; p = 0.002), active malignancy (OR 1.79; p = 0.012), and delirium during the first SICU stay (OR 1.86; p = 0.030). UR-SICU patients had longer hospital stays [46 vs. 13 days; p < 0.001] and higher hospital mortality (27.1% vs. 1.48%; OR 24.68; p < 0.001). Mortality remained higher at 6 months (33.3% vs. 7.1%) and 1 year (42.3% vs. 11.1%). Conclusions: UR-SICU occurred in 6.4% of patients and was independently associated with age, malignancy, and delirium. Readmission was strongly linked to prolonged hospitalization and increased short- and long-term mortality. Early recognition of high-risk patients and targeted, personalized preventive strategies may help reduce avoidable readmissions.

Patients with severe traumatic brain injury (STBI) often experience an abnormal hemostasis that contributes to mortality and unfavorable neurological outcomes. Objectives: We aimed to analyze epidemiologic, clinical, and laboratory factors associated with mortality in patients with STBI during the first 48 h after in-hospital admission. Methods: We performed an observational retrospective study of STBI patients with associated extracranial trauma [defined as Injury Severity Score (ISS) ≥ 16 with an Abbreviated Injury Scale (AIS) head and neck ≥ 3 and Glasgow Coma Scale (GCS) ≤ 8] admitted to a Level II trauma center over seven years (2015–2021). Patients were divided into two groups: survivors and dead. We assessed differences regarding demographics, trauma severity, hemodynamics, disability, need for surgery, length of stay, transfusions, need for massive transfusion protocol, and hemostatic laboratory parameters at different time points. Results: A total of 134 STBI patients were included. Patients who died were older, mostly men, and showed higher trauma severity and disability. Hemoglobin, platelets, and clotting parameters deteriorated after admission to the emergency department (ED) with significant differences between groups within the first 24 h after admission. Platelet count < 150 × 10³/μL at ED arrival, GCS, and age were independent risk factors for mortality. Conclusions: Older age, GCS, and platelet count at ED arrival were independent risk factors for mortality in STBI patients with associated extracranial trauma. Early thrombocytopenia < 150 × 10³/μL at ED arrival may be used as a simple prognostic tool to early predict mortality between non-isolated STBI.

Background: Liver transplantation (LT) is a crucial intervention in patients with severe liver disease. Infections by multidrug-resistant bacteria (MDRB) complicate the prognosis of the liver transplant patient. Main objective was analyze perioperative risk factors for MDRB infections six months after transplantation. Methods: A retrospective systematic review of 133 medical records of liver transplants performed between October 2018 and May 2022 is performed. The presence of MDRB colonization and infection, as well as various perioperative variables, are recorded. These data are analyzed to determine possible risk factors associated with MDRB infection and colonization. Results: Univariate analysis identified several perioperative associated with MDRB infections within six months after LT. Multivariate logistic regression analysis revealed that pre-transplant MDRB colonization (OR 5.72, 95% CI 1.7–18.7, p = 0.005) and the need for dialysis during the postoperative ICU stay (OR 6.42, 95% CI 1.7–23.4, p = 0.009) were independent risk factors for developing MDRB infections within six months following LT. MDRB infection (9.4%) is not associated with an increase in mortality (p=0.126). Conclusion: The results of the present study allow us to expand our knowledge of the epidemiology and pathophysiology of MDRB infection in the postoperative period of liver transplantation. This knowledge is important in order to establish prevention and treatment strategies for these infections that could improve the results in these patients.

Hypoalbuminemia and advanced lymph node involvement are independent predictors of septic shock. These findings underscore the importance of multidisciplinary perioperative optimization strategies, including nutritional assessment and tailored surgical planning, to mitigate the incidence and consequences of this life-threatening complication.
