We investigated the skin oxygen tension (tcpO2) of critically ill patients before, during and after transfusion (XF) of packed red blood cells (RBC).
Nineteen critically ill patients (11 men, age 67 ± 15 years, SAPS II 60.1 ± 19) who received 2 U RBC due to hemoglobin (Hb) <8 g/l underwent measurement of tcpO2 (TCM400; Radiometer Ltd, Copenhagen, Denmark) at the dorsum of one hand. Each patient served as her/his own control (baseline, after XF of 1, and second RBC). Ventilation and pressors were kept constant. Patients with bleeding, in shock and with circulatory assists were excluded. Cardiac index (CI) was determined by FloTrac™/Vigileo™.
XF significantly increased Hb and calculated DO2 but not true tcpO2. Increase in DO2 occurred in the absence of changes in CI and oxygenation. ScvO2 significantly decreased during XF but did not completely recover until the end of the study period.
