Does right latissimus dorsi cardiomyoplasty improve left ventricular function by increasing peak systolic elastance ( Emax )?
These results show that, in this acute canine model, right latissimus dorsi cardiomyoplasty significantly improves left ventricular function while decreasing left ventricular volumes. The results are consistent with the theory that cardiomyoplasty increases contractility while unloading the ventricle by decreasing end-diastolic volume. This increase in Emax despite inconsistent changes in other indexes underlies the importance of using load-insensitive indexes of ventricular function when studying cardiomyoplasty.
Bilateral superficial cervical plexus block with 0.75% ropivacaine administered before or after surgery does not improve postoperative analgesia after total thyroidectomy.
