importance of drug user detection

Conditions: Drug Addiction

Summary: 1. identify the illicit drugs (morphine, cannabinoids, benzodiazepines, barbiturates, tramadol, cocaine, amphetamine, alcohol, synthetic cannabinoids). 2. identify illicit drug users in patients who admitted in assiut university hospitals undergoing emergency operation and their percent among all patients admitted for emergency operation, for proper selection of anaesthetic agents and proper care before, during and after operations. 3. compare between addict and non addict in using suitable anaesthetic agents and doses - period of anaesthesia- period of recovery- complications. 4. compare between addict and non addict patients in :( vital signs before, during and after operation by using anaesthetic chart). 5. identify the importance of using drug abuse detection as a routine lab work before urgent operations.

drug addiction has become a more common problem worldwide. in many countries drug abuse is rapidly increasing among young generations .by taking routine preoperative history, it has been noticed that there is a high percentage of patients who were addicted to different types of drugs. drug addiction remarkably increases morbidity and mortality among patients. addiction could be defined as a chronic disorder characterized by the compulsive use of a substance, resulting in physical, psychological or social harm to the user and continued use despite that harm . substances that could be abused are so many: alcohol, sedative and hypnotics, opioids, cocaine and amphetamines, cannabis, hallucinogens and nicotine. they can be classified as socially acceptable drug (e.g., alcohol, tobacco), a medically prescribed drug (e.g., diazepam), and illegal substance (e.g., cocaine) . both acute intoxication and chronic abuse of these substances present challenges for anesthetic management during and after an operation .whereas some procedures may be delayed while the issue is addressed, others are urgent or emergent and the surgeon and anesthesiologist must be able to deal with the physiologic changes that may occur in these patients. so, it is important to understand the situations of drug users, such as the category of drugs used, the dosage, the duration of drug use, their history of detoxification or abstention, and especially their current abuse of drugs. pain threshold in addicts is lower than ordinary people who are not addict to opium due to several reasons including change in function, sensitivity reduction, or decrease in opioid's receptors. nevertheless, they are more resistant against narcotics and analgesic drugs. with little information about the history of drug abuse, a quick screening for recent use of drugs is important for both medical staff and patients. the immune colloidal gold (icg) technique is a well-established technique and is commonly used for screening for drug abuse . awareness of the drug's pharmacodynamics, pharmacokinetics and interaction with anesthetics medication is crucial to the proper management of illicit drug users during the perioperative period. moreover, it is common for illicit drug users to have infection with human immune-deficiency virus (hiv), hepatic c virus (hcv), syphilis or other sexually transmitted disease (std), which may put medical staff in danger. incidences of intraoperative and postoperative complications are increased in illicit drug users such as pulmonary infection and coagulation disorders . death of drug abusers during anaesthesia and intra operative may occur due to severe cardiovascular cocaine toxicity if general stabilization and hemodynamic control not achieved . the preventable perioperative complications are evaluated to improve the safety of health care, including also the medical-law point of view . on the other side, research was done in 2016 at johans hopkins found that the average of 250.000 people die in us because of medical errors each year. updating for this study in 2020 found that the serious medical errors occur most frequently in icu, emergency departments and operation rooms. many lawsuits are filled each year against doctors. for these reasons and more it is important, to the patients and medical staff, to make preoperative drug abuse analysis as a mandatory before emergency surgeries to achieve optimal management during and after operations.
