Acute potassium changes during CPB

Cerebral protection during CPB

Despite advances in surgical, anesthetic, and neuroprotective strategies, cerebral injury after cardiac surgery remains a significant source of post-operative morbidity and is responsible for an increasing proportion of peri-operative deaths. Technological advancements have allowed cardiac surgery to be performed on a progressively older and sicker population who, in turn, are at increased risk...

Serum potassium changes during induction of anaesthesia.

Serum potassium levels of 53 patients before and after induction with halothane and oxygen, halothane, nitrous oxide and oxygen, and thiopentone, showed a significant decrease after reaching the first surgical plane. After the administration of the depolarizing agent suxamethonium serum potassium levels increased significantly more in the two halothane groups than in the thiopentone group. It i...

Changes of serum potassium during renal homotransplantation.

Peripheral tissue oxygenation during standard CPB and miniaturized CPB (direct oxymetric tissue perfusion monitoring study).

AIM The aim of this study was to compare the impact of standard cardiopulmonary bypass (CPB) with mini CPB on peripheral tissue perfusion. METHODS 24 patients with ischemic heart disease scheduled for CPB were randomised to two groups: Group A (12 patients, standard CPB) and Group B (12 patients, mini CPB). Oxygen tension was measured with an optical multiparametric sensor inserted into the p...

Effect of timolol on changes in serum potassium concentration during acute myocardial infarction.

One hundred and six patients with acute myocardial infarction admitted to hospital within four hours after the onset of symptoms were randomised to treatment with intravenous timolol (54 patients) or placebo (52 patients). Serum potassium concentrations were estimated at frequent intervals during the first 24 hours of admission. Patients in both treatment groups, who did not receive subsequent ...
