Perioperative transoesophageal echocardiography with low-dose dobutamine stress for evaluation of myocardial viability: a feasible approach?
The feasibility of low-dose dobutamine stress combined with transoesophageal echocardiography (TEE) to detect viable left ventricular myocardium was evaluated in 22 anaesthetised patients prior to sternotomy for elective coronary artery bypass grafting (CABG). ⋯ Since we regard the visual assessment of LVWM as being more applicable for this protocol than the semiautomatic analysis, we conclude that low-dose dobutamine stress echocardiography seems to be a feasible method for detecting viable myocardium in the anaesthetised patient scheduled for elective CABG surgery. However, the semiautomatic analysis complemented our findings, since the variations in pre- and afterload did not significantly change the size of the left ventricle, which hereby would imply LVWM changes.

Randomized Controlled Trial Comparative Study Clinical TrialPrevention of nausea and vomiting in female patients undergoing breast surgery: a comparison with granisetron, droperidol, metoclopramide and placebo.
Breast surgery is associated with a relatively high incidence of postoperative nausea and vomiting (PONV). This study was undertaken to evaluate the efficacy of granisetron, droperidol and metoclopramide for preventing PONV after breast surgery. ⋯ Granisetron is highly effective for reducing the incidence of PONV in female patients undergoing breast surgery. Droperidol and metoclopramide are ineffective in this population.
