Sufentanil is one of the opioids currently used to induce general anesthesia, and cough is one of the most common complications. Many drugs have been used to prevent sufentanil-induced cough (SIC), and dezocine is one of them. Dezocine is an analgesic, acting as partial antagonist of κ-receptors and agonist of μ-receptors. The purpose of our meta-analysis is to evaluate the efficacy of dezocine on SIC. |
