OBJECTIVE: Approach to the pharmacodynamics of cisatracurium in newborn. METHODS: Sixty patients were randomized to two groups: Group Ⅰ and Group Ⅱ , received( iv) 2ED95 or 3ED95 cisatracurium in 5 seconds respectively, n=30. Neuromuscular transmission was monitored and Intubation conditions were assessed at 120s after cisatracurium administration using a 4- part scale. Observe onset time, TOF no reaction period, duration of action, recovery index, duration in vivo. RESULTS: The muscular blockage and conditions of intubation after 120s were different between two groups( P0. 05) . CONCLUSIONS: 3ED95 cisatracurium produces quicker, safer onset time and acceptable intubating conditions in the great majority of newborn than 2ED95. The TOF no reaction period, duration of action and duration in vivo were longer in 3ED95 group than in 2ED95 group, but recovery index are no significant between 2 groups with dosage.

Objective To investigate whether antenatal administration of dexamethasone would provide protection against cerebral hypoxic ischemic damage in asphyxiated fetal rats. Methods Fifty seven fetal rats of twenty day gestational age were randomly divided into five groups: sham operation (normal control, n =11), asphyxiated control (group E, n =10), and group D 1?D 2?D 3 of different timings of intravenous dexamethasone treatment (1 mg/kg) in pregnant SD rats ( n =15, 12, and 9 respectively). The times assigned for dexamethasone injection were thirty minutes before clamping, the time aroung clamping and the beginning of reperfusion respectively. Intra and extra cellular concentrations of calcium, sodium and potassium in fetal rat brains were measured in each group after thirty minutes of reperfusion. Results (1)Intracellular free calcium concentrations of fetal rat brains in group E,D 1, D 2 and D 3 were 552?94, 438?105, 445?57, and 456?110 nmol/L respectively, and all significantly higher than that in the normal control 315?87 nmol/L ( P

Objective To compare the operational feasibility and efficacy of inguinal obturator nerve block (ONB) beside the vessel by ultrasound combined with nerve stimulation and traditional ONB guided by nerve stimulation preventing obturator nerve reflex. Methods Forty patients with American Society of Anesthesiology (ASA)Ⅰ or Ⅱ, aged 35~91 years who underwent transurethral electric excision of bladder tumor in our hospital in 2014 were ran-domly divided into beside vessel group (group V, = 20) and traditional group (group T, = 20). Adductor strength was measured before and after the block. Frequencies of obturator nerve block puncture, operation time, visual ana-log scale (VAS) pain score, and incidence of complications were recorded during and after ONB. Results The suc-cess rate of the first puncture was significantly higher in group V than that in group T ( <0.01). The operation time in group V was significantly shorter than that in group T ( < 0.01). The decreased degree of adductor strength has significant difference of the two groups ( < 0.05 or < 0.01). The VAS pain score in group T was higher than that in groups V ( < 0.01). There are two cases contract blood vessel in group T, while none in group V ( < 0.01). There was no case with the local anesthetic toxicity and paresthesia in the area of the obturator nerve and the obtu-rator nerve injury in the two groups. Conclusion Compared with traditional ONB guided by nerve stimulation, in-guinal ONB beside the vessel by ultrasound combined with nerve stimulation showed more accurate positioning, less adjustment, less puncture time, more comfortable and safe.
