Abstract
OBJECTIVE: We performed a meta-analysis from randomized controlled trials to evaluate the efficiency and safety between local infiltration analgesia and intrathecal morphine for pain control in total knee and hip arthroplasty.
METHODS: We systemically searched electronic databases including Embase (1980-2016.7), Medline (1966-2016.7), PubMed (1966-2016.7), ScienceDirect (1985-2016.7), web of science (1950-2016.7) and Cochrane Library for relevant articles. All calculation was carried out by Stata 11.0.
RESULTS: Four randomized controlled trials (RCTs) involving 242 patients met the inclusion criteria. The meta-analysis showed that there were significant differences in terms of postoperative pain scores at 24 h during rest (P = 0.008) and mobilization (P = 0.049) following total knee and hip arthroplasty. Significant difference was found regarding the incidence of nausea (P = 0.030), vomiting (P = 0.005), and pruritus (P = 0.000) between two groups. There was no significant difference between groups in terms of morphine equivalent consumption at postoperative 24 or 48 h.
CONCLUSIONS: Local infiltration analgesia (LIA) provided superior analgesic effects within the first 24 h compared to intrathecal morphine (ITM) following total knee and hip arthroplasty. There were fewer adverse effects in LIA. Doses of morphine consumption were similar in the two groups.
