Does mean strain throughout the heart cycle by longitudinal two-dimensional speckle-tracking echocardiography enable early prediction of infarct size?
Longitudinal global mean strain provides improved early prediction of infarct size in patients with AMI compared with longitudinal global strain and left ventricular ejection fraction.
A low dose of clonidine such as 75 micrograms doubled the duration of analgesia produced by 2 mg of morphine and a dose of 150 micrograms further increased the duration of postoperative complete analgesia without increasing the incidence of side effects. The morphine requirements during the postoperative period (36 hours) was greatly reduced by the addition of clonidine to the analgesic epidural mixture.
