Swan-Ganz
1.Hemodynamic monitoring of 21 cases with acute heart failure (AHF) were undertaken with Swan-Ganz flow-directed thermodilution catheterization and Model 9520 cardiac output computer.
2.Colour Doppler evaluate pulmonary artery pressure(PAP) preoperation and monitor pulmonary artery pressure(PAP),central venous pressure (CVP),continuous cardiac output(CCO) with Swan-Ganz at intraoperation and postoperation.
3.The comparison of effects of nitroglycerin, prostaglandin E_1 (PGE_1) and propranolol on infarction size (IS) and hemodynamics during acute myocardial infarction (AMI) were studied by epicardial mapping, N-BT evalution and Swan-Ganz catheterization, etc.
4.In addition intra-arterial BP, ECG, SpO2, PET CO2 and nasal temperature were monitored. Results Continuous cardiac output measured with TDEE and Swan-Ganz catheter (CCO/SvO2) were highly correlated (R = 0.801, P < 0.01, n = 480) .
5.Hemodilution(HD)and its effects on hemodynamics were studied in 24 patients with valvular heart disease bymeans of Swan-Ganz catheter monitoring technique and artery hematocrit(Hct)detection during operation for car-diac valve replacement.
6.Anesthesia was in duced with sodium hydroxybutyrate-fentanyl-thiopental and was maintained with sevoflurane,Swan- Ganz catheter was used to monitor the hemodynamic changes Results RAP and SVRI were increased before sitting position (P<0.05),but HR,cI,SI,LVWI,RVWI and RVSWI were decreased further more (P<0.01 ), SVRI constantly increased (P< 0.01 ), the hemodynamic parameters were kept stable after 60-min sitting position;
7.Methods Twenty eight patients scheduled for posterior fossa and posterior cervical spinal surgery, were anesthetized with sevoflurane fentanyl pancuronium or enflurane fentanyl pancuronium after intravenous induction. Pulmonary hemodynamics were monitored with Swan Ganz catheter technique and Qs/Qt was calculated from the data of arterial and mixture venous blood gas analysis, including the following parameters: CI, RAP, MPAP, PCWP, PVRI, pHa, PaCO 2, PaO 2, PaO 2/FiO 2 and Qs/Qt.
