Anesthesia Guidelines for Cannabis Users
Does cannabis use impact levels of anesthesia during surgery? The American Society of Regional Anesthesia and Pain Medicine (ASRA Pain Medicine) has developed guidelines for screening patients, presurgery, for cannabis use. Use of cannabis—whether recreational or medicinal—can interact and affect anesthesia. Therefore, “anesthesiologists should ask patients if they use cannabis…and be prepared to possibly change the anesthesia plan or delay the procedure in certain situations,” stated Samer Narouze, MD, PhD, senior author and ASRA Pain Medicine president. The guidelines were compiled from literature and personal experiences of experts, from anesthesiologists to physicians to patient advocates.
There are 21 recommendations, which are graded and range from:
- All patients being screened presurgery
- Counseling cannabis users about pre- and postsurgery pain control
- Notifying those pregnant about cannabis use risk to the fetus
- Potentially postponing elective surgery based on timing of cannabis use
- Adjusting ventilation settings based on cannabis use
- Approving opioid usage for pain but also increasing risk watch
Dr. Narouze commented, “They also need to counsel patients about the possible risks and effects of cannabis. For example, even though some people use cannabis therapeutically to help relieve pain, studies have shown regular users may have more pain and nausea after surgery, not less, and may need more medications, including opioids, to manage the discomfort. We hope the guidelines will serve as roadmap to help better care for patients who use cannabis and need surgery.”
