 Fluid management is an important part of perioperative care for patients undergoing neurosurgery. It is necessary to maintain normal blood volume levels and avoid excessive osmolarity. The best way to do this is by administering the right amount of fluids at the right time. There are some differences of opinion regarding which type of fluid should be used and how much should be given. Recent studies have shown that certain types of fluids may be more effective than others, but further research is needed before any definitive conclusions can be drawn. In general, however, it is important to ensure that the patient's body is well hydrated throughout the surgery and recovery process. This article was authored by Tihariu.
