Accuracy of non-invasive hemoglobin monitoring by pulse co-oximeter during liver transplantation.
Hemoglobin level monitoring is essential during liver transplantation (LT) due to substantial blood loss. We evaluated the accuracy of non-invasive and continuous hemoglobin monitoring (SpHb) obtained by a transcutaneous spectrophotometry-based technology (Masimo Corporation, Irvine, CA) compared with conventional laboratory Hb measurement (HbL) during LT. Additionally, we made subgroup analyses for distinct surgical phases that have special features and hemodynamic problems and thus may affect the accuracy of SpHb. ⋯ SpHb was demonstrated to have a clinically acceptable accuracy of hemoglobin measurement in comparison with a standard laboratory device when used during LT. This technology can be useful as a trend monitor during all surgical phases of LT and can supplement HbL to optimize transfusion decisions or to detect occult bleeding.

ReviewUltrasonography for neuraxial blocks: a review of the evidence.
This narrative review summarizes the evidence derived from randomized controlled trials (RCTs) pertaining to the use of adjunctive ultrasonography (US) for neuraxial blocks. ⋯ Published reports of RCTs provide evidence to formulate limited recommendations regarding the use of adjunctive US for neuraxial blocks. Further well-designed RCTs are warranted.
