Preoperative screening for illicit drug use in patients undergoing emergency surgery: A prospective observational study

Knowledge of illicit drug users (IDUs) is important because of the comorbidity related to drug use. In this prospective, observational study, we screened 1007 patients undergoing emergency surgery and found that 75 of them (7.5%) were IDUs The results of preoperative screening showed that the rates of HIV and syphilis infection were significantly higher in IDUs (HIV (+) 2.6%, syphilis (+) 10.7%) than in non-IDUs (HIV (+) 0, syphilis (+) 0.5%). Intraoperative consumption of remifentanil (IDUs: 1.85 ± 1.30 vs. non-IDUs: 1.31 ± 0.86, p = 0.009), midazolam (IDUs: 4.82 ± 1.52 vs. non-IDUs: 4.15 ± 1.81, p = 0.002), and atracurium (IDUs: 31.5 ± 15.1 vs. non-IDUs: 25.5 ± 11.9, p = 0.006) and the proportion of patients requiring postoperative fentanyl (IDUs: 15 (20.0%) vs. non-IDUs: 95 (1.2%), p = 0.031) were significantly increased in IDUs compared to non-IDUs. Postoperative complications were observed in 22.7% (17/75) of patients who were IDUs, which was significantly increased when compared with non-IDUs (6.0%, 56/932, p < 0.001). The mortality rate within 30 days after surgery was similar between the two groups. These findings suggested that the IDUs were associated with increased rates of HIV and syphilis infection; greater consumption of intraoperative opioids, sedatives, and muscle relaxants; increased postoperative complications and a similar mortality rate within 30 days after surgery when compared with non-IDUs.

Are Alcohol Anti-relapsing and Alcohol Withdrawal Drugs Useful in Cannabinoid Users?

Cannabinoids are still classified as illegal psychoactive drugs despite their broad and increasingly acknowledged therapeutic potential. These substances are most famous for their wide recreational use, particularly among young adults to either alter the state of consciousness, intensify pleasure induced by other psychoactive substances or as an alternative to the previously abused drugs. It is important to emphasize that cannabinoids are often taken together with a variety of medications intended for the treatment of alcohol use disorder (AUD) or alcohol withdrawal syndrome (AWS). These medications include disulfiram, acamprosate, and naltrexone. In this paper, we summarize recent advances in the knowledge of possible beneficial effects and interactions between cannabinoids and drugs commonly used for treatment of AUD and AWS either comorbid or existing as a separate disorder.
