Effect of Intravenous Lidocaine on Serum miRNA-135a in Patients Undergoing Non-cardiac Surgery
Effects of Intravenous Lidocaine on Serum miRNA-135a and Its Downstream Proteins Rock2 and Add1 in Elderly Patients Undergoing Non-cardiac Surgery Under General Anesthesia.

Detailed Description
Postoperative cognitive dysfunction (POCD) is a major complication following surgeries and anesthesia, especially in elderly individuals. Lidocaine, an inexpensive, widely available, and relatively safe compound, is a local anesthetic that readily crosses the blood-brain barrier. Intravenous lidocaine can reduce the incidence of POCD. However, the mechanism is still unclear.
Rock2 and Add1, which are regulated by miRNA-135a, play a key role in learning, memory, and cognition.
The objective of this study is to investigate the efficacy of intravenous lidocaine on the incidence of early POCD, and the levels of Rock2, Add1, and miRNA-135a in elderly patients undergoing non-cardiac under general anesthesia.
