Effects of laryngeal LA pretreatment on baseline cardiorespiratory activity

Variable Saline LA
VT, mL/kg 8.0 ± 0.4 8.1 ± 0.4
fR, breaths/min 124 ± 5 126 ± 5
VE, mL·min−1·kg−1 990 ± 60 1,008 ± 50
TE, s 0.31 ± 0.02 0.30 ± 0.02
HR, beats/min 347 ± 14 346 ± 13
MABP, mmHg 69 ± 6 66 ± 6

Values are means ± SE. LA, liquiritin apioside; TE, expiratory duration; VT, tidal volume; fR, respiratory frequency; VE, minute ventilatory volume; HR, heart rate; MABP, mean arterial blood pressure. The data were obtained from 4 groups of pups in series I: n = 9 for capsaicin, 10 for HCl, 10 for distilled water, and 8 for air pulse.
