JUSTIFICATIVA E OBJETIVOS: O rocurônio é um bloqueador neuromuscular ( BNM) não-despolarizante de ação intermediária que apresenta início de ação. factores predisponentes de relajación residual neuromuscular fue un algoritmo gicos de los bloqueantes neuromusculares; situación que debe ser evitada debi- .. con la combinación de succinilcolina y un relajante no despolarizante. El Decametonio es, al igual que la succinilcolina, un miembro de los bloqueadores neuromusculares despolarizantes. Imprimir/exportar. Crear un libro · Descargar como PDF · Versión para imprimir.

Male Wistar rats weighing between and g were used. The animals were anesthetized intraperitoneally with urethane 1.

Bulbring 11 technique was used to evaluate the effect of ropivacaine on neuromuscular transmission, its influence on blockade produced by pancuronium and the effectiveness of neostigmine and 4-aminopyridine on neuromuscular blockade reversal. The nerve was placed over platinum electrodes connected to a Grass S48 stimulator.

The diaphragm was maintained, by its tendinous portion, under constant voltage 5. In Group III pancuronium—ropivacaine , pancuronium was added to the preparation 30min after the addition of ropivacaine.

Muscle response to indirect stimulation was recorded for 60min after addition of the drugs. In the rat diaphragm, the effects of ropivacaine on miniature endplate potentials and membrane potentials were also studied.

Parameters evaluated were 1 extent of diaphragm muscle response to indirect stimulation before and 60min after ropivacaine addition; 2 extent of diaphragm muscle response to indirect stimulation before and 60min after pancuronium addition, alone and previously combined with ropivacaine; 3 membrane potentials MP and miniature endplate potentials MEPP ; and 4 effectiveness of neostigmine and 4-aminopyridine on neuromuscular blockade reversal. Results were expressed as means and standard deviations.

Wilcoxon test was used to analyze the membrane potential of muscle fiber and the effectiveness of neuromuscular blockade reversal drugs.

To evaluate the reduction in the extent of muscle response, Student's t-test normal distribution was used. Results At the concentration studied and used alone, ropivacaine did not reduce the extent of muscle response to indirect electrical stimulation on rat phrenic nerve-diaphragm. With pancuronium alone and in preparations previously exposed to ropivacaine, the mean extent of muscle responses was Figure 1.

Amplitude of muscle response to indirect stimulation on phrenic nerve-diaphragm preparation of rats exposed to ropivacaine 5. Degree of blockade with pancuronium alone and in preparation previously exposed to ropivacaine. The neuromuscular blockade caused by pancuronium in preparations exposed to ropivacaine was both partially and fully reversed by neostigmine and 4-aminopyridine, respectively.

There was no significant effect of ropivacaine on membrane potentials Fig. Effects on miniature endplate potentials MEPP were characterized by a decrease in frequency and extent until complete blockade.

Figure 3. Ropivacaine 5. High doses increases the relaxation time, an average time of 67 min, with a range of min 3 7. While nationally, Andujar et al 6 compared the use of rocuronium in reverse order with the use of succinylcholine, and conclude that intubation conditions are good in both groups achieving a quick airway, in our medium, there is so far no work describing the clinical behavior of rocuronium.

Key words: Rocuronium. Case studies. Los datos fueron registrados en una planilla Excel y almacenados en una base de datos. A los 20 segundos encontramos que el TOF presentaba un valor menor en el grupo B comparado con el grupo A.

En cuanto al tiempo necesario para lograr 2 respuestas del TOF, fue mayor en el grupo B. En: Miller RD.

The nerve was placed over platinum electrodes connected to a Grass S48 stimulator. Florencia Sosa 1 , Dra. The presynaptic action was demonstrated by the decrease in the frequency and amplitude of miniature endplate potentials MEPP caused by ropivacaine, being the result of changes in quantal release of acetylcholine.

Effect of epidu-rally administered bupivacaine on atracurium-induced neuromuscular blockade. Parameters evaluated were 1 extent of diaphragm muscle response to indirect stimulation before and 60min after ropivacaine addition; 2 extent of diaphragm muscle response to indirect stimulation before and 60min after pancuronium addition, alone and previously combined with ropivacaine; 3 membrane potentials MP and miniature endplate potentials MEPP ; and 4 effectiveness of neostigmine and 4-aminopyridine on neuromuscular blockade reversal.
