ABSTRACT
The primary objective of this research was to systematize the existing studies done on the commonly used intravenous [IV] fluids, electrolytes and trace elements in the fluid replacement postoperative procedure. This particular meta-analysis was done in place of the traditional use of literature review, and for this reason, this research paper has compared opinions from various existing studies done by different scholars on synthesis. Also, this analysis has explored the best-identified guidelines that should be applied to postoperative patients. Although this analysis would give various advisories on the type of fluids and electrolytes used for replacement in postoperative patients, the primary emphasis would be to highlight the advantages and disadvantages of each identified replacement fluid. This also included the surgical and anesthetic techniques that should apply in the best practice guideline used, when dealing with postoperative patients
