stroke work index

stroke work in·dex

a measure of the work done by the heart with each contraction, adjusted for body surface area; equal to the stroke volume of the heart multiplied by the arterial pressure and divided by body surface area; the normal stroke work index does not exceed 40 g/m2.

RESULTS: The objective was to compare haemodynamic variables between the propofol group and the etomidate group during induction and orotracheal intubation, which includes the heart rate, arterial pressures (Systolic, diastolic, and mean), cardiac index, pulmonary artery pressures (Systolic, diastolic, and mean), central venous pressure, stroke volume index, systemic vascular resistance index, pulmonary vascular resistance index, left ventricular stroke work index, and right ventricular stroke work index.
Comparison of Left Ventricular Stroke Work Index (LVSWI) between two groups is shown in table 3 and chart 4.
ARDS: acute respiratory distress syndrome; PH: pulmonary hypertension; HR: heart rate; RAP: right atrial pressure; sPAP: systolic pulmonary artery pressure; dPAP: diastolic pulmonary artery pressure; mPAP: mean pulmonary artery pressure; PAOP: pulmonary artery occlusion pressure; CI: cardiac index; RVSWI = right ventricular stroke work index; LVSWI: left ventricular stroke work index; SVRI: systemic vascular resistance index; PVRI: pulmonary vascular resistance index.
Table 1--Mean values and standard deviation of heart rate (HR; beats [minute.sup.-1]), mean and pulmonary arterial pressure (MAP, mPAP), systemic vascular resistance index (SVRI; dynes seconds [cm.sup.-5] [m.sup.-2]), left and right ventricular stroke work index (LVSWI; cJ; RVSWI; cJ), pulmonary vascular resistance index (PVRI; dynes seconds [cm.sup.-5] [m.sup.-2]), pH, arterial partial pressure of carbon dioxide (PaC[O.sub.2]; mmHg) in female dogs submitted to anesthetic induction and maintenance using propofol in microemulsion (M; n=6) or lipid emulsion (E; n=6).
