Meta Analysis Comparative Study
High-dose versus low-dose opioid anesthesia in adult cardiac surgery: A meta-analysis.
We performed a systematic comparison of high-dose and low-dose opioid anesthesia in cardiac surgery. ⋯ Our data suggest that low-dose opioids, both short acting and long acting, are safe and effective to use in adult cardiac surgery patients, independent of the clinical characteristics of the patients and the type of opioid used. In view of the current opioid epidemic, low-dose opioid anesthesia should be considered for cardiac surgery patients.

According to the 2015 National Survey on Drug Use and Health, marijuana continues to be the most common illicit recreational drug used in the US. Cannabis is associated with systemic reactions that potentially affect perioperative outcomes. We have reviewed the most important pharmacological aspects and pathophysiological effects that should be considered during the perioperative management of chronic cannabis/cannabinoids users. ⋯ Severe vascular complications associated with cannabis exposure may include malignant arrhythmias, coronary spasm, sudden death, cerebral hypoperfusion and stroke. Bronchial hyperreactivity and upper airway obstruction are commonly reported in cannabis users. Postoperative hypothermia, shivering and increased platelet aggregation have been also documented.
