Intravenous lidocaine infusion for pain control after laparoscopic cholecystectomy: A meta-analysis of randomized controlled trials.

Background: This meta-analysis aimed to assess the efficiency and safety of intravenous infusion of lidocaine for pain management after laparoscopic cholecystectomy (LC).

Methods: A systematic search was performed in PubMed (August 1966-2017), Medline (August 1966-2017), Embase (August 1980-2017), ScienceDirect (August 1985-2017), and the Cochrane Library. Only randomized controlled trials (RCTs) were included.

[Effects of different anesthesia methods on perioperative hemodynamics and ECG in old CHD patients].

Objective: To explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.

Methods: The 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.
