Fluid and electrolyte balance is a crucial aspect of oral surgery, as it can significantly impact a patient's overall health and recovery. Oral surgery procedures can lead to fluid and electrolyte imbalances due to various factors such as bleeding, vomiting, and reduced oral intake. Fluid balance refers to the amount of water and electrolytes in the body, which is regulated by the kidneys, hormones like antidiuretic hormone, aldosterone, RAAS, and other mechanisms like the thirst mechanism. It is important for oral surgeons to closely monitor their patients' fluid and electrolyte levels and provide appropriate therapy as needed to support their recovery and overall well-being. Overall, maintaining proper fluid and electrolyte balance is crucial in ensuring successful oral surgery outcomes.
