Preoperative Considerations: One of the primary concerns in treating cannabis users is preoperative counselling. Patients are often advised to taper their cannabis use before surgery to minimise the risk of adverse effects. Increased cannabis use is associated with higher rates of myocardial ischemia and a greater tolerance to standard anaesthesia doses, which can complicate surgical procedures. Therefore, thorough preoperative evaluations are essential to identify and mitigate potential risks associated with cannabis use.
Intraoperative Challenges: During surgery, cannabis can influence anaesthesia management. Patients using cannabis may require higher doses of anaesthetics due to increased tolerance, leading to prolonged sedation and recovery times. These factors necessitate heightened vigilance and potentially adjusted anaesthetic protocols to ensure patient safety.
Postoperative Care and Cannabis: Postoperative care for cannabis users presents additional challenges. While studies offer mixed results, some suggest a correlation between cannabis use and increased incidences of postoperative pain, nausea, and vomiting. Conversely, topical cannabinoids may enhance wound healing, presenting a nuanced picture of cannabis’s role in recovery.
Drug Interactions and Cannabis Use Disorder: Cannabis also poses significant drug-drug interaction concerns, particularly with anticoagulant medications commonly used in postoperative care. These interactions require careful management to avoid complications. Additionally, the prevalence of cannabis use disorder among patients underscores the importance of screening. Short screening tools can help identify patients at risk, providing an opportunity to address potential complications proactively. (Source: JAMA)
