%X To determine the most effective pain-control procedure for open liver surgery through a network meta-analysis and provide a best developing direction in this field.
PubMed, Embase and Cochrane Library database were searched for randomized controlled trials up to 1 July 2016. We extracted data on post-operative pain score at the 4th-8th hour and 24th hour from studies that compared various pain-control strategies. Network meta-analysis was conducted in Aggregate Data Drug Information System software by evaluating the parametric pain score at rest and on movement. Cumulative probability value was utilized to rank the procedures under examination. The inconsistency would also be tested by node-splitting models.
Twelve articles containing 661 patients were included. Intrathecal analgesia plus intravenous analgesia played the most effective role in pain controlling at post-operative 4-8 h (both at rest and on movement, P = 0.49 and P = 0.62, respectively) and at post-operative 24 h (both at rest and on movement, P = 0.46 and P = 0.29, respectively). Node-splitting models test revealed that no significant inconsistency existed in this research.
Intrathecal analgesia plus intravenous analgesia revealed the most effective clinical pain-control value for open liver surgery. More importantly, we believed that creating a better comprehensive and systematic combined pain-control procedure should be considered as the developing direction in this field.
