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 The ECMO was safely withdrawn after multidisciplinary consultation.

Thrombotic thrombocytopenic purpura (TPP) successfully rescued by plasma exchange in the ICU: A report of two cases.

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening disorder, which is characterized by thrombus formation in small blood vessels. The present study retrospectively analyzed the clinical data from two patients with severe TTP, who were treated successfully in the intensive care unit (ICU) at the Liaocheng People's Hospital in 2013. Comprehensive therapies were administered to the patients, including plasma exchange (PE), mechanical ventilation (case 1 only), steroid therapy, blood transfusion and anti-inflammatory treatment (case 2 only).

[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.

[Relationship between blood NO and PaO2 or PaCO2 levels of patients with acute carbon monoxide poisoning].

Objective: To investigate the relationship between blood nitrogen monoxide(NO) and PaO2 or PaCO2 levels in patients with severe and moderate acute carbon monoxide poisoning.

Method: The blood levels of NO in patients with severe and moderate acute carbon monoxide poisoning was assayed with nitrate reductase method, and its correlation with the blood levels of PaO2 and PaCO2 was analyzed.

Results: The blood level of NO in patients with severe and moderate acute carbon monoxide poisoning were (36.
