Accidental placement of venous return catheter in the superior vena cava during venovenous extracorporeal membrane oxygenation for severe pneumonia: A case report.

Background: Venovenous extracorporeal membrane oxygenation (V-V ECMO) has become an important treatment for severe pneumonia, but there are various complications during the treatment. This article describes a case with severe pneumonia successfully treated by V-V ECMO, but during treatment, the retrovenous catheter, which was supposed to be in the right internal vein, entered the superior vena cava directly in the mediastinum. The ECMO was safely withdrawn after multidisciplinary consultation.

[Clinical study of cerebral oxygen utilization coefficients in patients with severe head injury].

Objective: To investigate the relationship in cerebral oxygen utilization coefficients (O.2UCc) in patients with acute severe head injury and illness prognosis.

Methods: Forty patients with acute severe head injury were studied, and 40 patients with light head injury were used as control.
