Clinical study of non-invasive hemodynamic monitor system in the severe acute pancreatitis combined with pulmonary edema

Abstract

Objective To study the significance of the non-invasive hemodynamic monitor system in the differential diagnosis of severe acute pancreatitis (SAP) combined with pulmonary edema. Methods Twenty-nine cases of SAP during fluid resuscitation treatment combined with pulmonary edema were reviewed and the data of the non-invasive hemodynamic monitor system was analysed and summarized.According to the diagnosis on discharge, 18 patients were enrolled in test group (noncardiogenic pulmonary edema group) and 11 patients were enrolled in control group (cardiogenic pulmonary edema group). The data of two groups were determined and compared. Results In control group, cardiac output [(3.34±1.09) L/min], cardiac index [(2.06 ± 0.46) L/ (min·m2)], stroke volume [(41.89 ± 13.72) ml], stroke index[(25.59 ± 7.32) ml/m2], accelerate cardiac index [(59.24 ± 28.41) L/100 s2], left cardiac work index [(2.09 ± 0.67) (kg·m)/m2], left ventricular ejection time[(254.32 ± 27.34) ms], ejection fraction (0.37 ±0.03) and velocity index [(27.11 ± 11.32) L/100 s] were all significantly lower than those in test group [(4.12 ± 1.06) L/min, (2.64 ± 0.48) L/ (min·m2), (46.21 ± 11.81) ml, (28.87 ± 5.32) ml/m2, (79.43 ±29.01) L/100 s2, (3.21 ± 0.84)(kg·m)/m2, (281.29 ± 29.11) ms,0.54 ±0.04, (39.34 ± 12.11) L/100 s,respectively] (P < 0.01); pre-ejectionphase [(116.54 ± 22.37) ms] and systolic time ratio (0.48 ± 0.04) were significantly higher than those in test group[(95.24 ± 21.41) ms,0.36 ± 0.02,respectively] (P < 0.01 or <0.05). Conclusion Non-invasive hemodynamic monitor system is helpful in the early differential diagnosis of SAP combined with pulmonary edema.
