Abstract:
Objective To evaluate the effect of hyperchloremia on acute kidney injury (AKI) in critically ill patients in a non-elective intensive care unit (ICU).
Methods The databases of PubMed, Embase, Cochrane Library, Web of Science, China Knowledge Network, Wanfang and VIP were accessed for searching the published literature on hyperchloremia associated with outcomes in critically ill patients up to September 29, 2022. Meta-analysis was performed by applying R language software using adjusted or unadjusted odds ratio (OR) and 95% confidence interval (95%CI).
Results A total of 15 studies involving 29 005 patients were included for Meta-analysis. Meta-analysis showed that the incidence of hyperchloremia was 43% in critically ill patients after admission into ICU (OR=0.43, 95%CI : 0.30-0.56). The risk of AKI was significantly elevated in critically ill patients with hyperchloremia (OR=1.35, 95%CI:1.10-1.64, P<0.01).
Conclusions Hyperchloremia is significantly associated with the occurrence of AKI in critically ill patients.
