Ultrasound-guided Blood Sampling Drawing for Microbiological Analysis in the Critically Ill

This study will test the feasibility of ultrasound-guided sterile blood sampling for critically ill patients with suspected sepsis requiring blood culture. The aim of the study is to evaluate the feasibility and safety of the use of ultrasound for blood cultures in a population of patients which can present difficult venous access and requiring more than one venipuncture attempt in general clinical practice
