Evaluation of preoperative cardiac risk index values in patients undergoing vaginal surgery

Article Abstract:

Standard risk evaluations of future heart complications may not apply to women undergoing elective vaginal surgery. Researchers used the New York Heart Association functional classification of heart disease and the Goldman cardiac risk index to measure heart problems in 406 surgery patients. Women over 55 years old or those who had their ovaries removed were classified as postmenopausal. Among 168 postmenopausal patients, there were two distinct risk factors associated with cardiac complications during surgery. These risk factors were hypertension and ischemic heart disease, which is constriction of blood vessels supplying the heart. Other factors, such as glucose intolerance, cardiac arrhythmia, and estrogen replacement therapy, did not predict heart problems. Eight menopausal women required intensive care following cardiac morbidity during surgery. Two patients died from heart attack. Gynecological surgery patients may not fit the general risk categories of heart disease.

Cardiac oxygenation by extracorporeal membrane oxygenation in exteriorized fetal lambs

Article Abstract:

Newborns that receive extracorporeal membrane oxygenation (ECMO) may receive better oxygenation of the heart through right atrium to umbilical vein ECMO than by the standard right atrium to carotid artery ECMO. ECMO is used for newborns with severe heart and lung conditions. Researchers compared the two forms of ECMO on seven fetal lambs. Right atrium to umbilical vein ECMO delivered more oxygen to the left ventricle of the heart and greater blood flow to the heart muscle than did right atrium to carotid artery ECMO. The left ventricle feeds oxygen to the rest of the heart. The left ventricle may receive more oxygen when oxygenated blood is reintroduced to the body through the umbilical vein. Prostaglandin was given to fetuses to prevent the ductus arteriosus from closing.
