Hemodynamic Data during Laparoscopic Low Anterior Resection

Values are expressed as means ± SD. CI: cardiac index, SV: stroke volume, SVR: systemic vascular resistance, C: control group, N: nitroglycerin group, T1: 10 min after induction of anesthesia, T2: 5 min after CO₂ insufflation with supine position, T3: 10 min after the Trendelenburg position with pneumoperitoneum, T4: 30 min after the Trendelenburgposition with pneumoperitoneum, T5: 1 hr after the Trendelenburg position with pneumoperitoneum, T6: 5 min after desufflation in the supine position, T7: 10 min after desufflation in the supine position, T8: 30 min after desufflation in the supine position. ^*Indicates P < 0.05 compared with T1. ^†Indicates P < 0.05 compared with the same time point as the C group. ^‡Indicates P < 0.05 compared with T2.
