The effect of HES130/0.4 sodium chloride solution on kidney function following early fluid resuscitation in shock patients

BACKGROUND: Doctors often use a small dose of hydroxyethyl starch (HES) 130/0.4 sodium chloride solution in the emergency room; however, its effect on kidney function remains controversial. This study aimed to evaluate the effect of a small dose of HES130/0.4 sodium chloride solution on kidney function in shock patients during early fluid resuscitation. METHODS: This cohort study retrospectively analyzed the data of 129 shock patients requiring fluid resuscitation who had been admitted to the Emergency Department of the Affiliated Hospital of Nantong University from January 2019 to December 2020. Patients were divided into the observation group (n=40) and control group (n=89) according to the type of fluid resuscitation. In relation to the fluid resuscitation treatment, the observation group was treated with crystalloid solution, while the control group was treated with crystalloid and HES130/0.4 sodium chloride solution. To further explore the effect of a small dose of HES130/0.4 sodium chloride solution, the patients were further divided into the following 4 groups based on the specific fluid administered: (I) the HES(+), lactated Ringer’s (LR)(+) group (n=85); (II) the HES(+), LR(–) group (n=4); (III) the HES(–), LR(+) group (n=31); and (IV) the HES(–), LR(–) group (n=9). The outcomes were in-hospital mortality and changes in creatinine (CR) level after fluid resuscitation. RESULTS: There were no significant differences in the in-hospital mortality rates between the observation and control groups (P=0.343). The CR levels of patients in the control and HES(+), LR(+) groups were reduced after fluid resuscitation (P=0.034; P=0.028). There was no significant change in patients’ CR levels in the HES(+), LR(–) group after fluid resuscitation (P=0.999). CONCLUSIONS: Administering a small dose of HES 130/0.4 sodium chloride in patients with shock does not appear to affect kidney function and in-hospital mortality; however, these findings should be considered exploratory, and further studies should be conducted to confirm these results.
