Abstract

BACKGROUND
Rocuronium(ORG 9426) is a new steroid nondepolarizing neuromuscular blocking drug with fast onset and intermittent duration of action. Its effects on vital signs are controversial. We studied onset, clinical duration, recovery index of rocuronium and its effects on blood pressures and heart rates.
METHODS
We selected thirty healthy children who would receive inguinal herniorrhaphy and allocated them to 2 groups(control and rocuronium group). Without premedication or with oral medication of PocralTM (20 mg/kg), they administrated propofol(2.5 mg/kg) intravenous for loss of consciousness and we maintained anesthetic states with 20 mg/kg/hr of propofol. After 2 minutes, we checked BP(SBP/ DBP/MBP) and HR at every minutes and checked TOF, T1 height compare to control, T4 to T1 at every twenty seconds. We injected intravenously rocuronium(0.8 mg/kg, 2ED95) to rocuronium group and nothing to control group. We determined intubation time(from injection to 90% depression of maximal block), onset time(to maximal depression or T1=0), clinical duration(to T1=25%) and recovery index(from T1=25% to T1=75%).
RESULTS
In children, intubation time was 93.8sec, onset time was 146.2sec, clinical duration was 34.6min, recovery index was 15.4min. SBP, DBP, MBP and HR were not changed independent of injection of rocuronium.
CONCLUSION
Rocuronium is a muscle relaxant with rapid onset and intermittent clinical duration in children. It does not affect BP and HR.
