Prognostic significance of intra-operative blood transfusions and flow measurements in reconstructive vascular surgery. | Intra-operative measurement of leg blood flow is useful not only for the detection of a technical fault. It has also proved to be a sensitive method to disclose hypovolaemia. Thus, if the blood volume is not restored, the peripheral vasoconstrictor tone remains elevated. In such a state, the basal leg blood flow is low... | 525,176 | [

Scalp-recorded frequency-following responses in neonates. | Low-frequency tone bursts (250, 500 and 1 000 Hz) were used to elicit frequency-following responses (FFRs) from full-term, healthy neonates. Easily identifiable FFRs were recorded from all well babies with stimulation at low-to-moderate levels (30-45 dB HLn). The amplitude and threshold values of neonatal FFRs were not... | 526,194 | [
