Anesthesiologists' Conduct Assessment towards the User of Cocaine at SUS Hospital with Accreditation. Knowledge through Questionnaire
Abstract
Introduction: In 1860, Albert Niemann isolated cocaine from leaves and reported that by placing the crystals on his tongue, and his tongue became benumb. In the Brazil is a country with greatest annual consumption rates becoming one of the biggest consumer markets of cocaine worldwide. The objective of this study, carried out through a questionnaire survey, was to find out the degree of knowledge of anesthesiologists from a tertiary hospital in their conduct towards a cocaine user.
Methods: The study is a research of descriptive exploratory, prospective, transversally cut, quantitative, through the application of a questionnaire in Department of Anesthesia with patients using cocaine. Anesthesiology residents of the hospital were excluded. The questionnaire (Appendix A) was applied from July to December 2020 with four identification questions and five open questions relevant to the objective of the study. To analyze the data, we use Descriptive Statistics graphs to profile the individual surveyed and build their respective distribution.
Results: The percentage of response was obtained in 66.6% of the teams, 28 men and 12 women. The duration of anesthesia practice ranged from 1 to 36 years. Of the 40 anesthetists, 75% suspend the surgery and 25% refer them to the operating room. All anesthesiologists find these patients during their month of work. Of the total 95% of anesthesiologists use clinical criteria. Of the 40 anesthetists, 36 believe that the guidelines for anesthesia in cocaine users should be reviewed.
Conclusion: Anesthesiologists, as perioperative physicians, have a vital role to play in the comprehensive care in patients with addiction to licit or to illicit drugs. The study showed that anesthesiologists need to be proactive and that there is a need to revise the guidelines for these patients.

Introduction
Cocaine is an ancestor of modern anesthetics. It is an alkaloid (benzoylmethylecgonine) derived from coca leaves in the Andean region of South America. In 1860, Albert Niemann isolated cocaine from leaves and reported that by placing the crystals on his tongue, and his tongue became benumb [1]. This important fact of his brilliant dissertation was the early recognition of the anesthetic properties of cocaine.Cocaine has its anesthetic properties preserved in its derivatives, being still used as a local topical anesthetic, mainly in ear, nose and throat surgeries [2].
In its illicit presentations it can be administered intranasally, injectable or through smoking and normally its effects last from 30 to 60 minutes [3]. It can cause ulceration of the nasal mucosa, anxiety, restlessness, tachycardia, hypertension, ventricular arrhythmias, asthma, pulmonary hemorrhage, thrombocytopenia and decreased levels of the plasma cholinesterase enzyme [3]. Its recreational and abusive use has become a serious health problem in virtually all countries and Brazil [4]. During regional anesthesia, its use can cause hypertension, as well as ephedrine-resistant hypotension, combative behavior and altered pain perception. During general anesthesia, on the other hand, may exhibit hypertension (during intubation), cardiac arrhythmia and develop an acute myocardial infarction [5]. This study published in 2015, showed that there is a clear need for institutions to make practical guidelines or recommendations for the perioperative management of patients who abuse cocaine [5]. The education of doctors on the evidence that supports or refutes the safety of general or regional anesthesia in this scenario is equally important [5].
Cocaine metabolites have no stimulating action, and the test normally performed on urine remains positive for 6 to 14 days, so it is not a good marker for acute poisoning, reflecting only that it has been used in the recent past [6]. For the proper functioning of any surgical center, the cancellation of the surgery is an excellent indicator of its quality. Several hospitals remain using 7-day abstinence to perform surgery on cocaine users [7].
Recently, in an Editorial it was proposed to carry out studies to scientifically modify the surgery cancellation time in a cocaine drug addict patient [8], after the publication of two case reports with less than 31 hours of use [9].
Research is used in any branch of science. However, excellent research is much more difficult to carry out than it appears. Researchers in the field of anesthesiology use research to evaluate behaviors, attitudes and knowledge of both doctors and patients, or to determine the characteristics of the population, such as disease states, and practices or results [10]. Several surveys are now carried out through questionnaires with clear questions using the fewest possible high-quality essential questions that will interest the target population [10].
The present study was conducted specifically to assess the level of awareness about assessment and the criteria for anesthesiologists to stop surgeries in the face of cocaine addicted patients, through a questionnaire with four identification and seven objective questions in an accredited Hospital Brazilian Health Care System (SUS). The second objective was after the results of this questionnaire to create a new guideline to be implanted in a hospital with a high amount of anesthesia in patients using cocaine.
Methods
The study is a research of descriptive exploratory, prospective, transversally cut, quantitative, through the application of a questionnaire on anesthesia in patients using cocaine. The research was carried out at the large tertiary Hospital Clínicas Municipal of São Bernardo do Campo (Brazilian System Health-SUS), newly accredited (International Qmentum Certification) with the anesthesiologist staff who perform their activities in number of 60 anesthesiologist. The inclusion criteria for this study were: Anesthesiologist staff of both genders, that accepted to participate in the study, and sign the Term of Informed Consent (TIC). Anesthesiology residents of the hospital were excluded.
The reason for the choice was the fact that the researcher works as an anesthesiologist in the Hospital, simplifying the work of data collection, and the study was registered in the Brazil Platform. Data collection was formalized by the approval by the Ethic Committee in Research numbered.
Data collection was carried out in the period to be determined from July to December 2020 with the aid of an instrument for data collection with four identification questions and five open questions relevant to the objective of the study (Appendix). The distribution and collection of questionnaires were provided by the researcher anesthesiologist.
To analyze the data, we use Descriptive Statistics graphs to profile the individual surveyed and build their respective distribution, in view of their use for visual representation of the information and to facilitate its interpretation. The respective graphs were constructed using an Excel spreadsheet and through the R Commander plug in for the R version 4.1.0 software available for free.
Results
Of the 60 staff of the Department of Anesthesiology 40 responded to the questionnaire making a percentage of 66.6% of participation, 12 women (30%) and 28 men (70%). For the study, two age groups were considered, with 20 participants between 27 and 35 years old and 20 participants over 35 years old.
The time of practice in the specialty ranged from 1 to 36 years, with 15 anesthetists from 1 to 5 years old, 15 anesthetists from 6 to 10 years old, five anesthetists from 11 to 20 years old and five over 21 years old. The average length of experience in the specialty who answered the questionnaire was 9.85 ± 9.14 years and the time working at the institution was 5.7± 6.3 years.
The fundamental research question (Number 5) showed that 75% of anesthesiologists cancel the surgery against 25% who refer the patient to the operating room.
Figure 1 shows the answers to the 1st question correlating with the presence of scheduled elective surgery in patients using cocaine, with all 40 anesthetists have always found cocaine users, varying according to the questions asked.
Figure 2 correlates whether there is a formal hospital policy regarding the use of cocaine, with 16 (40%) anesthetists knowing that there is, 16 (40%) anesthetists that there is a well-established consensus to suspend the surgery, with less than seven days of use, and 8 (20%) anesthetists have no consensus.
Figure 3 shows 95% of anesthesiologists use the screening criteria that are based on the patient's clinical history of use or even the perception in the medical record.
Figure 4 correlates when screening is performed and the majority (36 responses = 90%) during the preoperative visit, the morning of the procedure, or both responses.
Figure 5 shows that 90% of anesthesiologists who cancel or postpone surgery in a percentage above 50%.
Finally, Figure 6 shows the importance of having norms or guidelines for tracking the use of illicit drugs and especially cocaine, answered by 36 (90%) of the 40 anesthetists consulted.
Discussion
Substance use disorder has three stages: Binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation [11]. The anesthesiologist can usuallyintervene in any of these three stages. However, together with the interprofessional health team, an anesthetic plan must be developed after the Informed Consent Form has been informed and signed.In order to determine a guideline in our service, this questionnaire showed that 75% of anesthesiologists cancel the surgery against 25% who refer the patient to the operating room. And 90% of the anesthetists consulted believe that the Hospital must have a program and guidelines for performing surgery on cocaine users.
The prevalence rates of snorted and smoked cocaine in Brazil suggests that the country is amongst thenations with greatest annual consumption rates becoming one of the biggest consumer markets of cocaineworldwide [12]. Prevention and treatment policiesshould take this into consideration and strengthen the focus oncocaine use in the country.
The expansion of cocaine use shows the need to create effective prevention strategies and the need for protocols to deal with these patients in hospitals, especially in emergency and surgery units. Our hospital serves a large number of patients who are victims of motorcycle accidents and the creation of a strict care protocol was the reason for knowing anesthesiologists' knowledge regarding this problem.Our survey through a questionnaire showed that all 40 (100%) of anesthesiologists find patients using cocaine every month of the year.
Cocaine in any form is rapidly hydrolyzed in plasma with a half-life of around 90 minutes [6]. Its metabolites have no stimulating action, but the urine test can be positive for 6 to 14 days. Thus, the urine cocaine test is a poor marker for intoxication [13]. The cancellation of surgery among patients who screen positive for cocaine use is a common practicein many surgical centers.Because of these concepts, in a recent Editorial [8] and case report [9] it was proposed to review the seven-day time to wait for surgery should be a procedure to be reviewed.
Anesthesiologists should assume the importance of the pre-anesthetic visit, highlighting the greater propensity for perioperative complications in cocaine users.Our study showed that 95% of anesthesiologists use the screening criteria that are based on the patient's clinical history of use or even the perception in the medical record. It also showed that the majority (90% of anesthesiologists) perform the exam during a pre-anesthetic visit, on the morning of the procedure or in both situations. Finally, 90% of anesthesiologists believe that the implementation of guidelines on anesthetic conduct in cocaine users should be urgently implemented.
Conclusion
Drug abuse, especially with licit or illicit drugs, continues to grow worldwide and Brazil represents a large share [12,14]. Consequently, anesthesiologists may be involved in the care of patients under the acute and chronic influence of a myriad of substances. Anesthesiologists, as perioperative physicians, have a vital role to play in the comprehensive care in patients with addiction to licit / legal agents (eg. tobacco, alcohol) or to illicit / illegal drugs (heroin, cocaine, marijuana, etc.) [15]. This study of anesthesiologists' knowledge about cocaine use shows that they need to be proactive in obtaining a current or past history of drug abuse, modify the guidelines and understand that the metabolite present in the urine is a poor marker of acute intoxication, that is perfectly perceived by the clinical method.
The cancellation of surgeries is a topic being studied worldwide and that still requires investigations and interventions, as it is harmful to those involved and to the health system.
