What is Best to monitor intraoperative myocardial ischemia (infarction) is and explain in detail?
C i.e. Transesophageal echocardiography Tranoesophageal echocardiography provides a real time picture of all 4 cardiac chambers and valves. It can identify any malfunctioning valves in addition to any wall motion abnormalities related to myocardia ischemia. It is very useful during anesthesia. Abnormal motion of ventricular wall detected in this way is a reliable index of myocardial ischemia and may guide drug therapy, can identify if therapy has successfully treated the ischemia or indicate the need for fuher surgical revascularization CVP (catheer in central vein) measures right sided filling pressure whereas pulmonary aery catheter measures/monitors left hea filling pressure. Aerial cannulation measures direct systemic aerial pressure and facilitate sampling of aerial blood for analysis.
