For intra-operative neuromonitoring, indirect stimulation of the RLN is superior to direct stimulation. An intact acoustic IONM signal is highly predictive of intact postoperative RLN function. When the IONM signal is abnormal or absent, a one-stage extensive thyroid resection should be performed only if the surgeon is absolutely convinced that the first RLN is not harmed or a total thyroidectomy is mandatory.

In a paired study 12 platelet concentrates (PC) of Fresenius AS-104 cell separator were stored in new polyolefin bags of Fresenius (LE 2) and Fenwal PL-732 bags. On day 0 and after 3 and 5 days of storage pH, pO₂, pCO₂, cell counts, platelet morphology and aggregability, plasma glucose, lactate, LDH and βTG were determined. The overall changes fell within the expected range. No relevant differences between the two bags could be detected, although a few parameters (pH, pCO₂) are slightly but statistically/significantly different. It can be concluded that the new polyolefin bag is well suited for 5-day storage of PC’s from the AS-104.
