Patients despo,arizantes intravenous neuromuscular blocker and were divided in two groups of 16 patients: Rathmell JP, Brooker RF, Prielipp RC et al – Hemodynamic and pharmacodynamic comparison of doxacurium and pipecuronium with pancuronium during induction of cardiac anesthesia: Ann Fr Anesth Re-anim. Services on Demand Article. Monitoring of neuromuscular blockade in general anesthesia.
The Valle del Cauca anesthesiologist claims to frequently use neuromuscular blockers in general anesthesia. The use of neuromuscular blockers is potentially risky in our environment. V ; Gustavo Cimerman, M. In summary, the use of NDNMB in general anesthesia is frequent in our environment, but monitoring is dewpolarizantes. A survey of practice of neuromuscular block in the United States and Europe.
In our environment, the minimum safety standards in anesthesia consider the “monitoring of the muscle blockade with the peripheral nerve stimulator as highly desirable”.
Materials and methods With prior authorization by the INCS ethics committee, a descriptive, cross-sectional study was designed based on a telephone survey to all the anesthesiologists, members of the Society of Anesthesiology neuromuscularea Resuscitation SARVAC.

TOF-Guard was installed after anesthetic induction and ulnar nerve stimulation was only started when patients were asleep. The use of neuromuscular non-depolarizing blockers and their reversal agents by anesthesiologists Valle del Cauca, Colombia.
Our conclusion was that, similar to other nondepolarizing neuromuscular blockers, pipecuronium also has neuromuscualres onset shortened if priming dose is administered three minutes before total dose. A descriptive, cross-sectional study including anesthesiologists, and a review of the data from the Eye and Hearing Clinic for Blind and Deaf Children in Valle del Cauca to collect information about the use of neostigmine and the number of surgeries performed under general anesthesia between and The answers to question 4 were grouped by States or Cities when the Universities were national, or rated as foreign when the University was in a country other than Colombia.
Priming action mechanism may be explained by the wide safety margin in neuromuscular transmission. Brechner 2 published his article: The limited use of reversal agents and rare monitoring may be exposing our patients to a preventable morbidity-mortality resulting from the use of these drugs. Neuromisculares 1 – pipecuronium with priming: Which University did you go to for your specialization in anesthesiology?
Pipecuronium bromide is a long-lasting aminosteroid with major cardiovascular stability, however, with late onset. Br J Anaesth, ; Similar observations were reported by other authors using different neuromuscular blockers, such as vecuronium 8pancuronium 9 bpoqueadores atracurium Although the limitations of the study prevent us from establishing the cause of these two trends, in terms of safety one must consider a possible decline in the use of non-depolarizing neuromuscular block.
Some authors 11 have studied the priming effect of pipecuronium as compared to bolus injection of the same drug and have observed results similar to ours. Participated in this study 33 adult patients of both genders, aged 20 to 65 years, physical status ASA I or II, to despooarizantes submitted to elective surgeries under general anesthesia.
Can J Anaesth, ; However, there is a broad spectrum of adverse effects, ranging from an unpleasant feeling of weakness, delayed discharge from the OR or neuromjsculares PACU, to respiratory depression that compromises the safety of our patients.
Pipecuronium bromide is a long-lasting nondepolarizing neuromuscular blocker. Kopman AF, Eikermann M. Our results have shown statistically significant differences between groups with and without priming, indicating that pipecuronium also has its onset neuromuscularse, similarly to other known neuromuscular nekromusculares.
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.

Out of every ten patients that you administer general anesthesia and use non-depolarizing neuromuscular blockade, you reverse:.
As mentioned before, the interviewee was asked to choose a range based on an X number out despolarzantes every ten anesthetic procedures.

Conclusions The use of neuromuscular blockers in general anesthesia is a current practice in our environment. None of these situations is new, 14,15 however, there is considerable room for improvement in controlling the preventable adverse events associated with RB, including establishing clear rules on the need to monitor and record any residual block and encourage the availability of the new reversal agents, as well as implementing educational campaigns.
Conflict of interests None declared. Results Of a total of anesthesiologists, members of the regional society at the time of the interview, surveys were fully completed.
Group 2 – pipecuronium without priming: The concern for the complications derived from their use, particularly the residual neuromuscular block, have encouraged many studies and recommendations, but leading to little change in the behavior of anesthesiologist over time. The comparison between the number of surgeries and the use of neostigmine at the INCS in the last four years reveals a decline in the use of NDNMB reversal agents, and this is consistent with results of the survey showing that Parametric variables were defined as those with continuous ratio scale and distributed within the normality curve, confirmed by Shapiro Wilk test.
An educational campaign to address the pharmacokinetics of NDNMBs and their antagonists may help in developing safety standards for the use of NDNMBs; 16 for instance, obligatory monitoring, 17 or the implementation of recommendations on the use or reversal agents.
Table I show means, percentage distributions and differences between groups in demographics, physical status and onset.
Clinical limitations of acetyl cholinesterase antagonists. Pipecuronium bromide is a long-lasting aminosteroid neuromuscular blocker, with negligible cardiovascular effects until DE 95 0. V ; Marcelo Kirsch, M. RESULTS Data were analyzed by descriptive statistics and represented in central trend measurements and error, mean and standard deviation and percentage count, vloqueadores shown in table I. The limitation of this descriptive and cross-sectional study is that it prevents us from establishing associations with the usage patterns of NDNMBs.
