The use of neuromuscular non-depolarizing blockers and their reversal agents by anesthesiologists Valle del Cauca, Colombia. Assistant Professor Universidad del Valle. 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 Thirty two per-cent of the anesthesiologists are believe that they almost never use neuromuscular blockade reversing agents.
Twenty five per-cent said they occasionally reversed their patients, while 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 Valle del Cauca anesthesiologist claims to frequently use neuromuscular blockers in general anesthesia.
Although the study is not conclusive with regards to the associations based on the data collected, it does suggest that the habit of using neuromuscular blockers in our environment is risky. 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.

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.
Brechner 2 published his article: In our environment, the minimum safety standards in anesthesia consider the “monitoring of the muscle blockade with the peripheral. 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. 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.
The questions were strictly read out, and the level of comprehension and the skill of the surveyor were verified by the authors. All the information was collected within one-month. The only exclusion criterion was the reluctance of the anesthesiologist to respond to the survey.
In addition to the demographic variables, i. The following is a description of the questions and the possible answers. Only one answer could be given per question.
Out of every ten patients that you administer general anesthesia, you use non-depolarizing neuromuscular blockers in: Out of every ten patients that you administer general anesthesia, you use neuromuscular blockade monitoring in:. 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 of every ten despolraizantes procedures. Each range was then assigned an ordinal scale as follows table The answers to question neuuromusculares 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.
The use of neostigmine and neuromuscukares number of general anesthetic procedures performed during the last 4 years were concurrently quantified at the INCS. Of a total of anesthesiologists, members of the regional society at the time of the interview, surveys were fully completed. The other 18 were not answered in full or in part. Their average age was 42 years for women and 46 for men. 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.
Despolarlzantes 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.
The limitation of this descriptive and cross-sectional study is that it prevents despolarizqntes from establishing associations with the usage patterns of NDNMBs.

However, it does reflect the behavior of anesthesiologists in a particular region. It must be noted that according to the universities of origin, almost half of the doctors surveyed received their anesthesiology degree from universities in regions other than the Valle del Cauca, or graduated abroad. This fact leads us to consider the possibility for these results may reflect what happens around the country as a whole.
However, there is a deespolarizantes spectrum of adverse effects, ranging dspolarizantes an unpleasant feeling of weakness, delayed discharge from the OR or the PACU, to respiratory depression that compromises the safety of our patients.
The potential risks associated with RB can be serious for the lungs, including severe upper airway obstruction, atelectasis, pneumonia, and death. In our country, the most widely used drug is neostigmine, but there are some questions on the use of this product; i. 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.
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 bloqueadoers period 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.
An additional limitation is a probable information bias that we tried to avoid with the design of the trial and the test tool, in addition to the selection of the population. In summary, the use of NDNMB in general anesthesia is frequent in our environment, but monitoring is unusual. The reasons for such low frequency neuromuscularez 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.

The comparison between the number of surgeries and the use of neostigmine. And, how many preventable adverse events occur?
This study highlights the risk associated with the use of NDNMB and the potential preventable complications, probably as a result of poor neuromuscculares or the false belief that anesthesiologists have with regards to the safety of medium or intermediate acting blockers. 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.
The use b,oqueadores neuromuscular blockers in general anesthesia is a current practice in our environment. Monitoring of neuromuscular blockade is unusual among the anesthesiologists who practice in Valle del Cauca. The use of neuromuscular blockers is potentially risky in our environment. Decreased reversal and infrequent monitoring may be placing our patients at risk of a morbidity-mortality resulting from the use of these drugs.

This paper attempts to despolarizanted 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. 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 and Resuscitation SARVAC.

Each range was then assigned an ordinal scale as follows table 1: Results Of a total of anesthesiologists, members of the regional society at the time of the interview, surveys were fully completed.
