Abstract:Objective To investigate the effect of baicalin capsules for acute mountain sickness(AMS) prevention with rapid airlift ascent to high altitude. Methods A randomized controlled trial was conducted on 80 healthy young men with baicalin capsules (0.5 g bid, n=32), rhodiola capsules (0.76 g bid, n=24), or placebo (n=24), for 2 days prior to airlift ascent (397 m) and for the first 3 days at high altitude (3658 m). AMS, oxygen saturation (SpO2), heart rate (HR), systolic blood pressure(SBP), diastolic blood pressure(DBP), pulmonary artery systolic pressure (PASP) and mean pulmonary arterial pressure (MPAP) were assessed both at 397 m and 3658 m. Results After high-altitude exposure, significantly fewer participants in the baicalin capsules group(n=8, 25.0%) and rhodiola capsules group(n=7, 29.2%) developed acute mountain sickness compared with participants receiving placebo (n=14, 58.3%) (P<0.05) . HR, SBP, DBP, PASP and MPAP increased with altitude exposure (P<0.05), and SpO2 decreased with altitude exposure (P<0.05). AMS, HR, SBP and DBP with baicalin capsules was lower than those with placebo (P<0.05); AMS, PASP, MPAP with rhodiola capsules were lower than those with placebo (P<0.05) and SpO2 was higher than that with placebo (P<0.05). Conclusions Baicalin capsules for AMS prevention also reduce HR, SBP and DBP with rapid airlift ascent to high altitude and rhodiola capsules for AMS prevention also reduce PASP, MPAP, increase SpO2 with rapid airlift ascent to high altitude.
