The aim of this meta-analysis is to identify the predictive strength in the current literature of OPRM1-A118G polymorphism to postoperative anesthetic reactions, including nausea, vomiting, pruritus and dizziness.
The association of the OPRM1 A118G genetic polymorphism with side effects, such as nausea and vomiting, caused by opioids during analgesia has not been well-represented by the literature .
