Invasive line placement in critically ill patients: do hemostatic defects matter?

Area of Science:

• Critical Care Medicine
• Hematology
• Medical Device Placement

Background:

• Prophylactic blood component transfusion is common before invasive line placement in patients with coagulation defects.
• Epidemiology of hemostatic defects in these patients is poorly understood.

Purpose of the Study:

• Determine the proportion of ICU patients with hemostatic defects before invasive line placement.
• Assess physician interventions to correct these defects.
• Evaluate the incidence of bleeding complications post-procedure.

Main Methods:

• Retrospective chart review of 490 intensive care unit (ICU) patients.
• Analysis of 938 arterial, pulmonary artery, and central venous line placements.

Main Results:

• 41% of patients had at least one hemostatic defect; 27% had severe abnormalities.
• 17% lacked preprocedure laboratory evaluation.
• Physician correction attempts were made in 37% of patients with defects.
• Low incidence of bleeding complications (16 patients), with only two life-threatening.

Conclusions:

• Invasive lines are frequently placed in patients with hemostatic defects, often without correction.
• Hemorrhage rates are low, linked more to physician experience than hemostatic defects.
• Preprocedure blood component use is generally not indicated, except for severe abnormalities.
