Abstract:
6 h (n = 20). Swan-Ganz catheter was left in place after surgry for 40h. MAP, HR, ECG, cardiac output (CO), cardiac index (CI), PAP, PCWP, CVP, SVR, PVR and DO_2,VO_2, O_2-extraction rate (O_2 ER) were measured and/or calculated immediately after operation (T_1), 16 h (T_2 ),24 h (T_3 ) and 40 h (T_4 ) after operation. Results VAS scores were significantly lower in PCIA group than thosein IM group at T_(2, 3, 4) (P
