All trials used a parallel design. Out of every ten patients that you administer general anesthesia and use non-depolarizing neuromuscular blockade, you reverse: Of a total of anesthesiologists, members of the regional society at the time of the interview, surveys were fully completed.

Funding Author’s own resources. Acta Anaesthesiol Scand, 34pp. In Group III pancuronium—ropivacainepancuronium was added to the preparation 30 min after the addition of ropivacaine. This paper attempts to determine the current practices with regards to the use of non-depolarizing neuromuscular blockers NDNMB including their monitoring, by means of a descriptive cross-sectional study through the administration of a survey to all the anesthesiologists, members of the Society of Anesthesiology and Resuscitation of the Valle del Cauca SARVAC.

And, how many preventable adverse events occur? We identified 18 dose-finding studies that included more interventions or control groups or both. The authors thank Marta Pulido, MD, for editing the A review of the trends with regards to the use of neostigmine versus the number of surgical procedures performed under general anesthesia at an Institution in Valle del Cauca showed that the use of the reversal agent has declined, although the number of general anesthesia procedures increased within the same time period Amplitude of muscle response to indirect stimulation on phrenic nerve-diaphragm preparation of rats exposed to ropivacaine 5.

Ropivacaine increased the neuromuscular block produced by pancuronium. Local anesthetics, particularly amino amides, are a group of drugs widely administered by different routes, such as topical, subcutaneous infiltration, peripheral nerve block, neuraxial anesthesia alone or combined with general anesthesia. Great thanks in advance! How to cite this article. Conflict of interests None declared.

Br J Anaesth, 58pp. Who could help me? The complete antagonism with 4-aminopyridine suggests presynaptic action of ropivacaine. Muscle response to indirect stimulation was recorded for 60 min after addition of the drugs.


Pancuronium blockade was potentiated by ropivacaine, and partially and fully reversed by neostigmine and 4-aminopyridine, respectively. To minimize the risk of systematic error, ho assessed the risk of bias of included np. Rev Bras Anestesiol, 55pp.

The design of this paper prevents us from claiming a relationship between the trend to a declining consumption of neostigmine and the increase in general anesthesia, although this statement is consistent with the answers to the survey, which indicate that anesthesiologists continue to use NDNMB, but rarely use reversal agents.

This neuromusculaers highlights the risk associated with the use of NDNMB and the potential preventable complications, probably as a result of poor monitoring or the false belief that anesthesiologists have with regards to the safety of medium or intermediate acting blockers. Effects on miniature endplate potentials MEPP were characterized by a decrease in frequency and extent until complete blockade.

This paper attempts to despolarizanres the current practices with regards to the use of non-depolarizing neuromuscular blockers NDNMB including their monitoring, by means of a. The reasons for such low frequency of NMBM may be several, including the non-availability of monitoring equipment, poor knowledge neuromuscjlares how to do it or interpret the monitoring, or the anesthesiologist believes in the safety of the so called “short” or “intermediate” lasting blocking agents.

Incidence and complications of postoperative residual paralysis. The limited use of despolarizantew agents and rare monitoring may be exposing our patients to a preventable morbidity-mortality resulting from the use of these drugs.

The activity in terms of the number of surgical procedures per year and the use of neostigmine units vials shown in figure 5illustrates that in76 vials were used per every patients at the Institute for Blind and Deaf Children, whilst in there was a drop to 20 vials per patients.

As mentioned before, the interviewee was asked to choose a range based on an X number out of every ten anesthetic procedures. A national survey on the practice patterns of anesthesiologist intensivists in neuromksculares use of muscle relaxants.

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. Two review authors extracted data independently. In our country, the most widely used drug is neostigmine, but there are some questions on the use of this product; i. The aim of this study was to evaluate in vitro the interaction neuromusculqres ropivacaine and pancuronium, the influence on transmission despolarizamtes neuromuscular blockade, and the effectiveness of neostigmine and 4-aminopyridine to reverse the blockade.


To evaluate the reduction in the extent of muscle response, Student’s t -test normal distribution was used. Interaction of muscle relaxants and local anesthetics bloqurantes the neuromuscular junction. No registered users and 9 guests. The ropivacaine concentration used was established in a pilot study and determined from booqueantes presented in studies carried out in Brazil, where other amino-amide local anesthetics with similar characteristics to ropivacaine were used.

The diaphragm was maintained, by its tendinous portion, under constant voltage 5. All trials reported on conditions for tracheal intubation; seven trials with participants described ‘events of upper airway discomfort or injury’, and 13 trials with participants reported on direct laryngoscopy.

It is believed that the greatest degree of neuromuscular blockade caused by pancuronium in rat diaphragm preparations previously exposed to ropivacaine, and evidenced by a greater reduction in the extent of muscle responses to phrenic nerve stimulation, is due to a presynaptic action of ropivacaine and not to the muscular fiber depolarizing action, as it was found in electrophysiological studies that bupivacaine at the concentration used did not modify the membrane potential of muscle fibers.

Monitoring of neuromuscular block and prevention of residual paralysis. The potential risks associated with RB can be serious for the lungs, including severe upper airway obstruction, atelectasis, pneumonia, and death.
