Hydration Methods for Cisplatin Containing Chemotherapy: A Systematic Review

Cisplatin-induced nephrotoxicity (CIN) can be prevented by fluid hydration, electrolyte supplementation, or forced diuresis; however, the best way to prevent CIN is still unknown. The aim of this study was to provide objective evidence on the optimal design of hydration schemes to prevent CIN based on an update of the literature.

A Pubmed and Embase search were conducted in December 2021 and repeated in April 2022 and March 2023. Two independent reviewers screened the articles. The included articles were categorized and reviewed per category.

Twenty-seven articles met the inclusion criteria. The included studies varied widely. Four out of seven studies investigating diuretics found a protective effect of adding mannitol to the hydration scheme. All six studies investigating duration and amount of volume of hydration found that a short-hydration scheme resulted in less CIN than a longer hydration scheme. Seven out of nine articles evaluating the role of electrolytes found that magnesium supplementation reduced the risk of nephrotoxicity. Three studies investigated the safety of oral hydration and concluded that nephrotoxicity did not occur more frequently after oral hydration.

The hydration scheme of cisplatin should be short and consist of a relatively small amount of volume. The scheme should include mannitol and magnesium supplementation. Head-to-head studies are needed to investigate the safety of furosemide compared with mannitol and the dose of mannitol and magnesium.
