Abstract:

Objective

To explore the ideal liquid therapy for patients with acute kidney injury (AKI) caused by septic shock at different stages.

Methods

A total of 122 patients with AKI caused by septic shock were selected from January 2013 to June 2017 in the Department of Critical Care Medicine, Quzhou No.3 Hospital in this retrospective study. According to the 28-day survival condition, 122 cases were divided into the survival group (66 cases) and death group (56 cases). The general data, heart rate, respiratory frequency, mean arterial pressure, central venous pressure, central venous oxygen saturation, blood lactate level at the time of septic shock, blood creatinine and urea nitrogen levels on the day of septic shock, and the daily fluid therapy for the first 7 d (D1~D7) after septic shock of patients in two groups were compared; then daily net liquid balance and cumulative 7 d liquid net equilibrium were calculated. According to whether or not to implement the early active fluid resuscitation (AIFR) and later conservative fluid therapy (CLFM), patients were divided into four subgroups: AIFR and CLFM received (39 cases), AIFR received (35 cases), CLFM received (23 cases) and AIFR and CLFM unreceived (25 cases) subgroups. The survival of each subgroup for 28 days was compared. Multivariate Cox proportional risk regression analysis was used to screen the related factors affecting the survival of 28 days and the Kaplan-Meier survival curves were drawn to compare 28-day survival among subgroups.

Results

The proportions of AIFR regimen (47/66 vs. 27/56; χ2=6.718, P=0.010), CLFM regimen (47/66 vs. 15/56; χ2=23.924, P < 0.001) and CRRT (41/66 vs. 23/56; χ2=5.382, P=0.020) in the survival group were significantly higher than those in the death group, while the APACHEⅡ score [(23.1 ± 6.6) vs. (25.2 ± 4.0); t=2.192, P=0.031] and proportion of AKIN Ⅲ stage [(23.1 ± 6.6) vs. (25.2 ± 4.0); t=5.682, P=0.017] were significantly lower than those in the death group. Multivariate COX regression analysis showed that unaccepted AIFR regimen [HR=3.151, 95%CI (1.749, 5.676), P < 0.001], unaccepted CLFM regimen [HR=3.278, 95%CI (1.794, 5.987), P < 0.001], untreated CRRT [HR=1.947, 95%CI (1.111, 3.409), P=0.020] and AKIN staging [HR=2.237, 95%CI (1.186, 4.604), P=0.014] were independent influencing factors of survival in patients with AKI induced by septic shock on the 28th day. In the four subgroups, the survival conditions of patients with AKI induced by septic shock were significantly different in 28 days (χ2=30.233, P < 0.001). Further comparison showed 28-day survival of patients receiving both AIFR and CLFM (34/39) was significantly better than that of patients who received AIFR (13/35), CLFM (13/23) and who received neither AIFR nor CLFM (6/25) (all P < 0.008).

Conclusion

The combination of AIFR and CLFM can improve the survival of patients with AKI induced by septic shock, and it may be an ideal liquid therapy.
