**4. Postoperative anesthesia care**

Anesthesia management does not discontinue at the end of the surgical procedure but when the patient is discharged from the postanesthesia care unit. It should be noted that potassium levels may increase suddenly even in the perioperative period. Therefore, the recovery nurse should pay close attention to ECG changes and possibly check the serum potassium if increase in potassium is suspected. Occasionally the timing of the next HD session may need to be advanced, especially for the patient that missed their regular HD session prior to the procedure. The criteria are varied between hospitals but consulting a nephrologist should be considered and common for any institute.
