The potent and rapid-acting opiates (fentanyl, sufentanil, alfentanil) can be used as the sole induction agents in cardiovascular surgery where hemodynamic stability is critical.
Objective To study the effect of Amrinone on hemodynamics,blood gas analysis and respiratory function in patients with pulmonary hypertension of chronic obstructive pulmonary disease(COPD).
The occurrence of adverse effects was also recorded.Results: Patients' demographic data, baseline hemodynamic profile and the laryngoscopic time did not differ among the five groups.
Flow chamber is one of the most effective equipment to study the response about blood corpuscle and endothelioid cells under the condition of hemodynamics in vitro.
MB leads little changes of hemodynamics due to inhibit cardiac sympathicotonia and pneumogastric nerve simultaneity, but TEB brings the evident changes due to only inhibit pneumogastric nerve.
In addition, the goals are to support the various organs using supportive measures like ventilator support, hemodynamic support, and transfusions if they're needed.
For minor maternal bleeding, bed rest is usually sufficient, but for major bleeding, blood products and intravenous fluids might be used to support hemodynamic stability.
Complications depend on the degree of hemorrhage and how far along the pregnancy has advanced, and treatment focus on hemodynamic support until a safe delivery is possible.
In some severe cases, where the maternal hemodynamics are worrisome and the fetal heart rate tracing shows signs of fetal hypoxia, an immediate cesarean section can be performed.
