<qa>  What is the most widely preferred initial fluid for fluid resuscitation in children with shockGiven this background, the investigators decided to compare the effect of two solutions on the incidence of acute kidney injury in children resuscitated with either of the two fluids. Children receiving volumes of at least 20 mlkg in the first hour of resuscitation as boluses would be enrolled and followed up for the proposed outcome variables. The investigators plan to enroll 708 patients over a period of 3 years. The investigators believe that the proposed study will provide the answer to the safety of normal saline which is the most widely preferred initial fluid for fluid resuscitation in children with shock due to sepsis.
