TEG is a moderate-complexed instrument. The QC requirements are strict and anesthesiolgists found it difficult to comply with the every 8 hours QC requirement at the OR setting. In addition, the group finds it difficult to spend adequate time to learn patient testing and interpretations. The implementation would go well if the anesthesiolgists are dedicated to the training and have enough time to practice QC/patient testing with the instrument. Some complained about the long duration to wait for the results.
Laboratoians can do a better job to run TEG on patients.
