Case Reports
Intravascular guide wire aspiration in a patient on extracorporeal membrane oxygenation: A case report.
Guide wire aspiration during central venous catheter (CVC) insertion in a patient on extracorporeal membrane oxygenation (ECMO) is a very rare but dangerous complication. A guide wire aspirated inside the ECMO can cause thrombosis, the ECMO to break down or shut off, and unnecessary ECMO replacement. ⋯ Care must be taken when inserting a CVC using a guide wire in ECMO patients: the guide wire should not be inserted deeply, it should be secured during insertion, the ECMO venous cannula tip requires proper positioning, and ECMO flow should be temporarily reduced.

Dyssynchronous diaphragm contractions impair diaphragm function in mechanically ventilated patients.
Pre-clinical studies suggest that dyssynchronous diaphragm contractions during mechanical ventilation may cause acute diaphragm dysfunction. We aimed to describe the variability in diaphragm contractile loading conditions during mechanical ventilation and to establish whether dyssynchronous diaphragm contractions are associated with the development of impaired diaphragm dysfunction. ⋯ Dyssynchronous diaphragm contractions may impair diaphragm function during mechanical ventilation.

Respiratory failure may affect up to 1 in 500 pregnancies, due to pregnancy-specific conditions, conditions aggravated by the pregnant state, or other causes. Management during pregnancy is influenced by altered maternal physiology, and the presence of a fetus influencing imaging, and drug therapy choices. ⋯ Hypocapnia reduces uteroplacental circulation, and some degree of hypercapnia may be tolerated in pregnancy. Delivery of the fetus may be considered to improve maternal respiratory status but improvement does not always occur.
