What should be monitored closely during surgery to avoid complications?

Monitoring all aspects—fluid balance, electrolytes, and vital signs—during surgery is crucial to avoid complications and ensure patient safety. Each of these components plays a significant role in the overall physiological status of a patient undergoing surgery.

Fluid balance is important because it helps to maintain adequate blood volume and pressure, preventing issues such as hypovolemia or fluid overload, which can lead to complications like shock or pulmonary edema.

Electrolytes are essential for numerous bodily functions, including muscle contraction and nerve function. Abnormalities in electrolyte levels can lead to arrhythmias, muscle weakness, and other serious problems during and after the surgical procedure.

Vital signs, including heart rate, blood pressure, respiratory rate, and oxygen saturation, provide immediate indicators of the patient's physiological state. Monitoring these signs helps detect any deviations from the norm, allowing for timely interventions to avert potential complications.

Considering the interconnectedness of these elements, it becomes clear that close monitoring of all three areas is fundamental during surgery, resulting in the choice of encompassing all of them as the best answer.
