Cocaine-Positive Patients Undergoing Elective Surgery: From Avoiding Case Cancellations to Treating Substance Use Disorders

The effect of cocaine on patients undergoing total hip arthroplasty

Background

Cocaine use has surged in the past decade, with 4.8 million Americans (1.7% of the population greater than 12) reporting use in 2021, leading to a healthcare burden of 1.3 billion dollars. Cocaine users experience prolonged hospital stays, higher costs, worse surgical outcomes, increased risk of medical conditions, and inflammation-related osteoarthritis. The study aims to identify factors influencing length of stay, costs, and perioperative complications in cocaine users undergoing total hip arthroplasty (THA) to reduce these risks.

Methods

This study utilized the NIS database, providing comprehensive information on patient demographics, length of stay, hospital costs, and complications. Statistical analyses were conducted using SPSS software, including propensity matching and significance testing, to compare outcomes between cocaine users (CU) and non-cocaine users (NCU) undergoing total hip arthroplasty.

Results

After propensity matching, cocaine users had a significantly longer LOS (4.8 days) in comparison to non-cocaine users (2.6 days) (p < 0.001). Similarly, the CU group had a larger of care (87984.9) than the NCU group (69149.2) (p < 0.001). Cocaine users had significantly higher rates of blood loss anemia (OR: 3.24, 95% CI: 2.21, 4.73), blood loss anemia (OR: 1.59, 95% CI: 1.12, 2.24), blood transfusion (OR: 2.23, 95% CI: 1.04, 4.78), periprosthetic dislocation (OR: 6.57, 95% CI: 1.47, 29.32), and periprosthetic infection (OR: 4.59, 95% CI: 1.54, 13.68) than patients in the non-cocaine user's group.

Conclusion

Cocaine users had a significantly longer length of stay, higher costs of care, and an increased number of post-operative complications compared to non-cocaine users. These data contribute to understanding the potential ramifications of cocaine users undergoing THA.

Cardiac surgery's long opioid dependency: time to recalibrate pain therapy?

Opioid analgesia is the cornerstone of anaesthetic management during cardiac surgery. However, a subset of patients use opioids persistently after 3 months of surgery. We discuss a recent meta-analysis and systematic review by Liu and colleagues describing both patient and peri-procedural risk factors that contribute to this phenomenon in the context of chronic pain after cardiac surgery. Anaesthetists for cardiac surgery should consider opioid alternatives and individual patient risk factors to optimise recovery and pain control.

Anesthetic Considerations for Patients on Psychotropic Drug Therapies

Psychotropic drugs are used in the treatment of psychiatric and non-psychiatric conditions. Many patients who are on psychotropic medications may present for procedures requiring anesthesia. Psychotropic medications can have dangerous interactions with drugs commonly used in anesthesia, some of which can be life-threatening. In this review, we describe the current anesthetic considerations for patients on psychotropic drug therapies, including antidepressants, antipsychotics, mood stabilizers, anxiolytics, and stimulants. The pharmacology, side effects, and potential drug interactions of the commonly prescribed psychotropic drug therapies with anesthetic agents are described. Further, we highlight the current recommendations regarding the cessation and continuation of these medications during the perioperative period.

Improving prediction to prevent perioperative morbidity

In this editorial, we examine how the STRoke After Surgery (STRAS) screening tool and similar risk scoring systems can be used to identify high-risk patients for postoperative stroke. Specific challenges to develop and implement preventative measures aimed at improving postoperative outcomes are discussed. Finally, we suggest potential future areas of research in this field.
