Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, Valve replacement patients undergoing cardiopulmonary bypass were randomly divided into control group and experimental group (SGB Group) , main outcome measures: postoperative complications (pulmonary infection, oxygenation injury, arrhythmia, hemorrhage, enteroparalysis, incision infection, renal insufficiency, cognitive impairment, etc.) and 30-day mortality. Secondary outcome measures: Hemodynamics, postoperative extubation time, length of stay and total cost of hospitalization. To investigate the effect of SGB on the rapid recovery of patients with Valve replacement heart disease after cardiopulmonary bypass.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this study was to investigate the effect of left stellate ganglion block on the incidence and severity of postoperative complications in patients with cardiac Valve replacement undergoing cardiopulmonary bypass, to compare the difference of inflammatory reaction between the control group and the stellate ganglion block group at different time points, and to preliminarily elucidate the molecular mechanism of stellate ganglion block in the protection of cardiac Valve replacement during cardiopulmonary bypass (CPB) . The first part is a prospective study on the effect of left stellate ganglion block on cardiac Valve replacement Hemodynamics during cardiopulmonary bypass (CPB) , the incidence, length of hospital stay, cost of hospital stay, and 30-day mortality of the common Valve replacement complications after cardiopulmonary bypass (pulmonary infection, oxygenation injury, arrhythmia, bleeding, intestinal paralysis, incision infection, renal insufficiency, cognitive impairment, etc.) , to determine the effect of left stellate ganglion block on rapid recovery from cardiac Valve replacement during cardiopulmonary bypass. In the second part, we collected the dynamic changes of inflammatory factors in plasma of control group and patients with stellate ganglion block before and 1,3,6,24 and 72 hours after operation, to explore the molecular mechanisms by which left stellate ganglion block promotes rapid recovery and reduces severe complications in patients with cardiac Valve replacement undergoing cardiopulmonary bypass (CPB) .

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Sixty patients with cardiac Valve replacement undergoing cardiopulmonary bypass were randomly divided into experimental group and control group, with 30 patients in each group. All patients signed the informed consent form. Control Group: the control group was injected with 6ml normal saline. Test group: the test group was injected with 0.5% ropivacaine 6ml.
