腹腔高压与肾灌注

Intra-abdominal hypertension and renal perfusion

腹腔高压通过一系列机制对肾血流及灌注产生影响,从而引起一系列病理生理变化,从局部血流紊乱开始,最终导致明显的器官功能衰竭。了解肾血流及灌注的生理学以及腹腔高压时肾血流动力学变化的病理生理学是重要的,这有助于早期识别腹腔高压造成的肾功能不全。超声、CT、MRI等影像学技术可帮助我们早期评估肾血流及灌注变化,促进早期干预,对于腹腔高压时急性肾损伤的早期诊断和保护肾功能具有重要的临床意义。

Intra-abdominal hypertension affects renal blood flow and perfusion through a series of mechanisms,resulting in a series of pathophysiological changes,which start from local blood flow disorders,and end with serious organ failure.It is important to understand the physiology of renal blood flow and perfusion as well as the pathophysiology of renal hemodynamic changes in patients with intra-abdominal hypertension,which is helpful for early identification of renal insufficiency caused by intra-abdominal hypertension.Ultrasound,CT,and MRI can be adopted to evaluate the changes of renal blood flow and perfusion in early stage,and promote early intervention,which are of great clinical significance for early diagnosis and protection of renal function in acute kidney injury caused by intra-abdominal hypertension.
