Effect of Blood Flow Rate on the Accuracy of Central Venous Pressure Measurement during Continuous Renal Replacement Therapy.

Background: The objective of this study was to study the influence of extracorporeal blood flow rate (BFR) on the accuracy of central venous pressure (CVP) measurement during continuous renal replacement therapy (CRRT).

Methods: Eligible patients were randomly divided into 3 groups based on the location of catheters used for their CRRT and CVP measurement. CVP levels measured at increased extracorporeal BFR (from 0 to 300 mL/min) in the normal and reverse positions of inlet and outlet lines connected to the CV catheter (CVC) in the course of the CRRT session were collected.

Detection of Early Cytokine Storm in Patients with Septic Shock After Abdominal Surgery.

To explore the characteristics of cytokine storm in patients with septic shock after abdominal surgery, examine its relationship with clinical data, and determine intervention timings. We prospectively observed a cohort of patients with abdominal infection admitted to the surgical intensive care unit (ICU) after surgery (shock group). A control group of healthy individuals was used for comparison.
