RESUMEN
Context: Septic shock (SS) can pose a high risk of death if rescue efforts in an emergency room aren't started in a timely manner. Thus, rapid and efficient treatment is of great significance to the SS patients' survival. T-α1 can enhance the cellular immune function of patients, and blood purification (BP) can improve the hemodynamics of SS patients by clearing inflammatory mediators in the blood. Objective: The study intended to explore the effects of Thymosin α1 (T-α1) plus blood purification (BP) on SS patients under the emergency green channel (GC), a fast and efficient service system that hospitals provide for acutely and critically ill patients. Design: The research team designed a randomized controlled study. Setting: The study took place in the Emergency Department at the Second Affiliated Hospital of Xi'an Jiaotong University in Xi'an, Shaanxi, China. Participants: Participants were 86 SS patients who came to the hospital for treatment between June 2019 and January 2021. Intervention: The research team numbered the patients in sequence according to the admission time of the patients, and then randomly numbered them by the computer, and assigned participants to an intervention or a control group, with 43 participants in the intervention group receiving T-α1 plus BP therapy and 43 participants in the control group receiving BP treatment only. Outcome Measures: The study measured preparation time before treatment, symptom-onset-to-door (SOTD), duration of shock, length of stay in the intensive care unit (ICU), and incidence of adverse reactions. The study also assessed changes between baseline and postintervention in inflammatory cytokines (ICs), immunological function, and myocardial-function markers. Finally, the research team conducted a one-year follow-up to determine participants' prognostic survival. Results: The groups showed no significant differences in the preparation time before treatment, SOTD, rescue success rate, and incidence of adverse events (P > .05), while the intervention group showed a significantly shorter duration of shock and length stay in the ICU and a significantly higher overall response rate (P < .05). The research team observed significant improvements in the T-lymphocyte subsets, ICs, and myocardial function in both groups postintervention, but the changes in the intervention group were significantly greater (P < .05). Follow-up results showed no significant differences in overall survival between the intervention and control groups (P > .05), but the average LC was significantly higher in the intervention group (P < .05). Conclusions: For SS patients, the combination of T-α1 and BP under the emergency GC can effectively improve their immunological and myocardial function, reduce inflammatory reaction, and prolong their LCs, which provides a greater guarantee of the effectiveness of treatment for SS patients in the future.
