Abstract:
Objective:Sepsis patients usually have a fever, but it is still controversial about whether sepsis patients with fever need cooling treatment. This study aimed to evaluate the effect of external physical cooling on the prognosis of sepsis patients.Methods:This study was a single-center, open-label, randomized clinical trial. Adult sepsis patients with body temperature above 38.3 °C admitted to the Critical Care Medicine of Northern Jiangsu People's Hospital from June 2020 to December 2020 were selected, and randomly assigned in a 1∶1 ratio to the cooling group and control group. Patients in the cooling group used external physical cooling methods to reduce their core body temperature to the normal range (36.5-37.5°C) within 4 h of enrollment and maintained for 48 h. Standard care was implemented in the control group at all times, and all antipyretic treatments were prohibited. The 28-day mortality, 72 h-Δ sequential organ failure assessment (SOFA) score (SOFA score at enrollment–SOFA score after 72 h), length of hospital stay and length of ICU stay were compared between the two groups.Results:A total of 53 patients (32 males and 21 females) were enrolled in the study, including 26 patients in the cooling group and 27 patients in the control group. There were no statistical differences in age, sex, source of infection, SOFA score and body temperature between the two groups (all P>0.05). There was no significant difference in the 28-day mortality between the cooling group and the control group ( RR=1.38, 95% CI: 0.62-3.07, P=0.430). The 72 h-ΔSOFA score of the cooling group was significantly higher than that of the control group, the mean difference between the two groups was 1.90 (95% CI: 0.09-3.71, P=0.040), and there was no significant difference in length of hospital stay, length of ICU stay and 28-day mortality between the two groups. Conclusions:External physical cooling management can not significantly reduce the 28-day mortality of sepsis patients. However, external physical cooling can reduce the 72-h SOFA score in sepsis patients, and improve the organ function of patients.
