Liposome Bupivacaine Compared to Plain Local Anesthetics to Reduce Postsurgical Pain: An Updated Meta-Analysis of Randomized Controlled Trials

Figure 5

Incidence of nausea during hospital stay. Random-effects meta-analysis evaluating the effect of liposome bupivacaine on nausea compared to control. Squares to the right of the middle vertical line indicates that local anesthetics was associated with increased odds of nausea, whereas squares to the left of the middle vertical line show that liposome bupivacaine was associated with decreased odds of nausea. The horizontal lines represent the 95% CI and the diamond shape represents the overall effect of liposome bupivacaine on postoperative nausea compared to standard local anesthetics. CI = confidence interval.
