Hypokalemia and Intravenous Patient Controlled Analgesia

General Anesthesia Clinical Trial

Official title:
Hypokalemia and Intravenous Patient Controlled Analgesia

Clinical Trial Summary

The increase in stress hormone level and hyperventilation caused by the postoperative pain may contribute to the development of hypokalemia during postoperative period. Therefore, if the postoperative pain is well controlled by the IV-PCA,the plasma potassium level during the postoperative period may be not affected by stress response. The researchers tried to investigate the effect of IV-PCA on potassium regulation during the postoperative period.

Clinical Trial Description

Intravenous patient controlled analgesia(IV-PCA) has been widely used to control postoperative pain. The increase in stress hormone level and hyperventilation caused by the postoperative pain may contribute to the development of hypokalemia during postoperative period. Hypokalemia is a risk factor for postoperative arrhythmia. Therefore, if the postoperative pain is well controlled by the IV-PCA, the plasma potassium level during the postoperative period may be not affected by stress response, and the incidence of hypokalemia may be reduced. The researchers tried to investigate the effect of IV-PCA on potassium regulation during the postoperative period.

The researchers divided the patients undergoing laparoscopic cholecystectomy into two groups of IV-PCA group and control group. The researchers compared the plasma potassium concentration from the preoperative to postoperative period. ;
