Invasive vascular catheterisation in the critically ill.
In order to identify potential problems and thereby minimise the risk of invasive vascular catheterisation, we conducted an analysis of these procedures in our medical intensive care unit with the aid of a computer database. During the 9-month study period 114 patients underwent 247 invasive vascular catheterisations, including pulmonary arterial (PA), central venous (CV) and arterial catheter insertions. Complications unique to PA catheterisation included burst catheter balloons (6%) and one serious episode of arrhythmia. The incidence of pneumothorax (2.8%) and inadvertent arterial puncture (2.2%) with PA and CV lines and our sepsis rate of 3.6% for all types of catheters are consistent with other studies. Arterial catheterisation proved to be relatively free of complications. Our study confirmed the safety of invasive vascular catheterisation. However, we review the precautions needed to limit potential complications.
