Perioperative Hemodynamic Changes During Video-Assisted Thoracoscopic Decortication for empyema

Table 3: Perioperative hemodynamic data obtained at each time point.

Data are means ± SD. T₀: supine two lung ventilation after induction; T₁: lateral decubitus position and two lung ventilation; T₂: lateral decubitus position and one-lung ventilation; T₃–T₁₄: every 5 min after decortication up to 60 min; T₁₅: end of surgery. HR: heart rate (beats/min); MAP: mean arterial pressure (mmHg); CVP: central venous pressure (mmHg); CO: cardiac output (L/min); CI: cardiac index (L/min/m²); SV: stroke volume (ml/beat); SVI: stroke volume index (ml/m²/beat); SVR: systemic vascular resistance (dyn.s.cm⁻⁵), SVRI: systemic vascular resistance index (dyn.s.cm⁻⁵.m²), SVV: stroke volume variation (%).^a P < 0.05 vsT_0,^bP < 0.01 vs T₀.
