Postoperative residual paralysis in outpatients versus inpatients. Each range was then assigned an ordinal scale as follows table Our results have shown statistically significant differences between groups with and without priming, indicating that pipecuronium also has its onset decreased, similarly to other known neuromuscular blockers.
Volatile inhalational anesthetics associated to pipecuronium usually prolong its duration. The use of neuromuscular blockers is potentially risky in our environment. Each range was then assigned an ordinal scale as follows table 1: In addition to the demographic variables, i. Can Anaesth Soc J, ; It must be noted that according to the universities dspolarizantes origin, almost half neuromusclares the doctors surveyed received their anesthesiology degree from universities bloqufadores regions other than the Valle del Cauca, or graduated abroad.
The reasons for such low frequency of NMBM may be several, including the non-availability of monitoring equipment, poor knowledge on 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.
Can J Anaesth, ; 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 Results Of a total of anesthesiologists, members of the regional society at the time of the interview, surveys were fully completed.

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.
Parenteral antibiotics, such as neomycin, streptomycin and gentamycin, in high doses, exacerbate neuromuscular block Low nondepolarizing blocker dose before the full dose is known to decrease the onset of most neuromuscular blockers.
Out of every ten patients that you administer general anesthesia and use non-depolarizing neuromuscular blockade, you reverse: The comparison between the number of surgeries and the use of neostigmine. All the information was collected within despolqrizantes. Monitoring of neuromuscular blockade is not a usual practice among them. Group 1 – pipecuronium with priming: 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.
This paper attempts to determine the current practices with regards to the use of non-depolarizing neuromuscular blockers NDNMB including their monitoring, neurlmusculares means of a. At the Institute for Blind and Deaf Children of Valle del Cauca INCSthe use of neostigmine is declining in contrast to the rising numbers of surgeries performed under general anesthesia from until 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.
Neuromuscular blocking agents are older than anesthesia despolqrizantes. Patients received intravenous neuromuscular blocker and were divided in two groups of 16 patients: 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.
Thirty two per-cent of the anesthesiologists are believe that they almost never use neuromuscular blockade reversing agents.
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. The survey was carried out by a non-medical person with technical training and experience in medical care and in making surveys to medical staff.
In our environment, the minimum safety standards in anesthesia consider the “monitoring of the muscle blockade with the peripheral nerve stimulator as highly desirable”. Problem of neu-romuscular block Reversion: Clinical Consequences, frequency and avoidance strategies.

Neuromuscular blocking agents Anesthesia Peripherial nerves General anesthesia. The study has shown that the priming technique was statistically acceptable in shortening onset, as compared to the other technique. Which University did you go to for your specialization in anesthesiology? In summary, the use of NDNMB in general anesthesia is frequent in our environment, but monitoring is unusual.
Fuchs-Buder T, Eikermann M. Their average age was 42 years for women and 46 for men. Parametric variables were defined as those with continuous ratio scale and distributed within the normality curve, confirmed by Shapiro Wilk test. Incidence and complications of postoperative residual paralysis.
A survey of practice of neuromuscular block in the United States and Europe. Exclusion criteria were patients with kidney or liver failure, neuromuscular diseases, in concurrent use of drugs influencing pipecuronium pharmacokinetics, and patients with family history of malignant hyperthermia.

Introduction Neuromuscular blocking agents are older than anesthesia itself. After the Ethics Committee, Hospital de Ensino Padre Anchieta, Hospital de Ensino Faculdade de Medicina ABC, participated in this randomized double-blind study 33 adult patients of both genders, aged 20 to 65 years, physical status ASA I and II, to be submitted to elective surgeries under general anesthesia with tracheal intubation and lasting more than 60 minutes.
Exclusion criteria were patients with kidney or renal failure, body mass index above 30, neuromuscular disease, family history of malignant hyperthermia or under drugs interfering with neuromuscular transmission. Pipecuronium bromide is a long-lasting nondepolarizing neuromuscular blocker. Monitoring of neuromuscular blockade in general anesthesia. 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.
