To evaluate the HemoCue plasma haemoglobin (Hb) analyser for determining supernatant Hb in red cell concentrates (RCC) during storage and compare this to a spectrophotometric method. ⋯ The HemoCue plasma haemoglobin analyser is a simple, rapid, reliable and accurate method for the determination of supernatant Hb in RCC at the end of storage and compares well to established methods for supernatant Hb measurement.

Comparative Study Clinical Trial Controlled Clinical Trial
Effects of solvent/detergent-treated plasma and fresh-frozen plasma on haemostasis and fibrinolysis in complex coagulopathy following open-heart surgery.
Solvent/detergent-treated plasma (SDP) contains markedly lower protein S (PS) and plasmin inhibitor (PI) activity than standard fresh-frozen plasma (FFP). It has also been reported that SDP contains no alpha(1)-antitrypsin. Despite the lack of clinical data, it is suspected that SDP may be less effective than FFP in the treatment of complex coagulopathies. We therefore conducted a prospective trial to study the impact of SDP and FFP on haemostasis and fibrinolysis in complex coagulopathy after open-heart surgery. ⋯ With the exception of PS and PI, SDP and FFP improved haemostasis and fibrinolysis to a similar degree. The clinical significance of these findings has to be determined in patients with severe acquired PS and PI deficiency requiring plasma transfusions.
