Background Multi-organ distress syndrome (MODS) causes morbidity in patients with trauma. This study evaluates the effectiveness of interleukin-33 (IL-33), which reflects tissue damage and the inflammatory response, as a MODS indicator in patients with trauma.
Methods Patients with trauma admitted to our trauma center between July 2022 and July 2023 were included. IL-33 levels were measured in blood samples for 4 days. Correlations with clinical and laboratory indicators, including initial IL-33 levels, were analyzed to identify independent predictors of MODS.
Results Among the 87 patients enrolled, 20 developed MODS. Initial IL-33 levels were elevated in the MODS group, compared with the non-MODS group. In the non-MODS group, IL-33 levels increased on day 1 and then declined, whereas in the MODS group, IL-33 levels were highest at admission (day 0) and decreased continuously through day 3. In patients with detectable initial IL-33 levels, the measured levels correlated with higher Abbreviated Injury Scale 5 scores and the Injury Severity Score (ISS). A logistic regression analysis revealed the ISS and delta neutrophil index as factors contributing to MODS progression.
Conclusions The findings suggest that initial IL-33 levels are elevated in the MODS group, compared with non-MODS group, and exhibit a rapidly declining trend, showing an initial association with MODS that was not maintained in a multivariate analysis. These findings suggest that IL-33 might have relevance in assessing trauma severity; however, further validation is required before it can be considered a biomarker for MODS.
Background Several recent studies have shown that preperitoneal pelvic packing (PPP) effectively produces hemostasis in patients with unstable pelvic fractures. However, few studies have examined the rate of surgical site infections (SSIs) in patients undergoing PPP following an unstable pelvic fracture. The purpose of the present study was to evaluate factors associated with SSI in such patients.
Methods We retrospectively reviewed the medical charts of 188 patients who developed hemorrhagic shock due to pelvic fracture between April 2012 and May 2021. Forty-four patients were enrolled in this study.
Results SSI occurred in 15 of 44 patients (34.1%). The SSIs occurred more frequently in cases of repacking during the second-look surgery (0 vs. 4 [26.7%], P=0.010) and combined bladder-urethra injury (1 [3.4%] vs. 4 [26.7%], P=0.039). The incidence of SSIs was not significantly different between patients undergoing depacking within or after 48 hours (12 [41.4%] vs. 5 [33.3%], P=0.603). The mean time to diagnosis of SSI was 8.1±3.9 days from PPP. The most isolated organism was Staphylococcus epidermidis.
Conclusions Repacking and combined bladder-urethra injury are potential risk factors for SSI in patients with unstable pelvic fracture. Close observation is recommended for up to 8 days in patients with these risk factors. Further, 48 hours after PPP, removing the packed gauze on cessation of bleeding and not performing repacking can help prevent SSI. Additional analyses are necessary with a larger number of patients with the potential risk factors identified in this study.
