Anesthesia and Electrolytes

disorders of electrolyte homeostasis are known at many diseases and clinical situations. They have serious consequences for the cell. The electrolyte therapy in patients, who have to undergo surgery, should begin preoperatively, so that an electrolyte balance without cellular deficits can be presumed at the beginning of the operation. It is very important to recognize an electrolyte imbalance in surgical patients and to equalize it.Elective surgery should be postponed in patients with significant hypernatremia (> 150 mEq/L) until the cause is established and fluid deficits are corrected. The advisability of proceeding with elective surgery in the presence of chronic serum potassium concentrations below 3.5 mEq/L is controversial, depends weather it’s acute or chronic. Anesthetic management consists of preventing a further increase in hypokalaemia by allaying anxiety, avoiding dextrose solutions, maintaining and the use of a nerve stimulator to assess neuromuscular blockade. A common recommendation is that serum potassium concentrations before subjecting patients to elective operations that require anesthesia. If this is not possible, it may be important to adjust anesthetic techniques to facilitate recognition of adverse effects of hyperkalemia intraoperatively and to minimize the likelihood of any additional increases in the serum potassium concentrations.
