중환자실(ICU)에서 치료받는 환자에게 투여되는 정맥 수액의 선택은 환자의 결과에 영향을 미치는 것으로 알려져 있다.
예) 4% albumin-traumatic brain injury에서 사망률 증가
hydroxyethyl starch-신부전 위험 증가
0.9% sodium chloride solution (saline; NS)은 전세계적으로 ICU에서 가장 많이 사용되는 수액 중 하나이다. 최근에는 NS의 사용은 신부전의 위험을 증가 우려가 대두되었다. 이후 balanced salt solution((i.e., crystalloid solutions with a chloride concentration closer to that in human plasma)의 사용이 증가되었다.
하지만 balanced solution vs 0.9% sodium chloride solution에 대한 임상적 효과(급성 신부전 완화 or 사망)에 대해서 명확하게 밝혀지지 않았다.
미국에서 진행된 open-label, cluster-crossover trial에서 NS vs balanced slat solution에서 balanced slat solution의 이점이 밝혀졌지만 더 작은 규모로 뉴질렌드에서 진행된 double-blind, cluster-randomized, double-crossover trial에서는 두 수액의 차이는 보이지 않았다.

Methods
double-blind, randomized, controlled trial
중증 환자(critically ill patients), BMES (Plasma-Lyte 148) or saline as fluid therapy for 90 days
primary outcome: death from any cause within 90 days after randomization
secondary outcome: receipt of new renal-replacement therapy and the maximum increase in the creatinine level during ICU stay

Conclusions
We found no evidence that the risk of death or acute kidney injury among critically ill adults in the ICU was lower with the use of BMES than with saline.
In our trial involving a heterogeneous population of critically ill adults, we found no evidence that the use of BMES in preference to saline in the ICU resulted in a lower all-cause mortality or risk of acute kidney injury. However, the confidence intervals around our results encompass a modest increase or decrease in either of these outcomes with the use of BMES.
