We tested the ability of mean acceleration (Acc) and peak velocity (V peak) of the aortic velocity signal measured by oesophageal Doppler to reflect left ventricular (LV) systolic performance. ⋯ V peak and, to a lesser extent, Acc measured by oesophageal Doppler behaved as markers of LV systolic performance as they were almost insensitive to fluid administration and changed to a much larger extent with dobutamine. These indices could be used to estimate LV systolic performance and to assess the effects of inotropic therapy.

Epidural anesthesia may reduce post-thoracotomy chronic pain (OR 0.33) and paravertebral block reduce that following breast ca surgery (OR 0.37).
