Comparison of Isotonic Versus Hypotonic Fluids in Neonates for Maintenance Fluid Therapy After Surgery

The goal of this clinical trial is to determine if isotonic or hypotonic fluids are more effective in maintaining serum sodium levels in neonates undergoing maintenance fluid therapy post-surgery. The main questions it aims to answer are: Does isotonic fluid therapy reduce the risk of hyponatremia compared to hypotonic fluid therapy? Does hypotonic fluid therapy lead to fewer cases of hypernatremia compared to isotonic fluid therapy? Researchers will compare neonates receiving isotonic fluids (Group I: isotonic/normal saline with 5% dextrose in 0.9% saline) to those receiving hypotonic fluids (Group H: hypotonic saline with 5% dextrose in 0.45% saline) to see if there are significant differences in serum sodium levels and associated complications. Participants will: Be randomly assigned to receive either isotonic or hypotonic fluids. Have blood samples taken before and after surgery to assess serum sodium levels. Be monitored for 24 hours post-surgery to observe any complications such as hyponatremia, hypernatremia, or edema. This study enrolled 84 neonates admitted to the neonatal intensive care unit following surgery, and data analysis was conducted using SPSS software version 25.0.
