Effect of right atrial appendectomy on the release of atrial natriuretic hormone.

摘要: Atrial natriuretic hormone is released from the right atrial appendage in response to distention. During cardiac operations usually partially removed or ligated for venous cannulation. To evaluate effect of appendectomy on release and its diuretic responses, we prospectively randomized into two groups 23 patients undergoing elective coronary artery bypass operations. There were 16 male 7 female with a mean age 62 ± years. Group A (n = 11) had removed, group B 12) preserved cannulation done lateral appendage. The comparable sexual distribution, age, number grafts, extracorporeal time. All normal left ventricular renal functions, they did not receive any diuretics during study period. studied both preoperatively postoperatively whereby serum levels, urine volume per minute, fractional excretion sodium, amount sodium excreted, central pressure measured before after expansion 5% albumin, 7.5 ml/kg. was no statistical difference these parameters preoperatively.
