Abstract
- Background: The establishment of pneumoperitoneum has impacts on patient's cardiovascular function. In this study, the respiratory variation of inferior vena cava (IVC), stroke volume (SV) index, and other parameters was monitored to determine how the pneumoperitoneum affects the patient's hemodynamic and acknowledge how to resolve it. Materials and Methods: Fifty-five patients were randomly divided into Group A (8 mmHg), Group B (10 mmHg), Group C (12 mmHg), Group D (14 mmHg), and Group E (12 mmHg, infusion with 7 mL/kg crystalloid solution). The parameters including IVC variability, SV index, mean artery pressure (MAP), heart rate (HR), cardiac output index (CI), and airway pressure were measured, to compare the changes before and after pneumoperitoneum. Results: Among Group A, Group B, Group C, and Group D, there were no significant differences in patients' prepneumoperitoneum information. Compare with prepneumoperitoneum, the difference in IVC variability, SV index, MAP, HR, CI, and airway pressure was statistically significant (P < 0.05). After the establishment of pneumoperitoneum, the difference in IVC variability, SV index, and airway pressure among Group A, Group B, Group C, and Group D was statistically significant (P < 0.05). Compare with Group C, the change rates of IVC variability, SV index, MAP, HR, and CI were smaller in Group E (P < 0.05). Conclusion: The establishment of pneumoperitoneum could increase the patient's IVC variability and reduce SV index, and with the increase of pressure, IVC variability had an increasing trend, SV index had a decreasing trend. Fluid transfusion could reduce the relative influence of the pneumoperitoneum. [ABSTRACT FROM AUTHOR]
