Hydromorphone vs sufentanil in patient-controlled analgesia for postoperative pain management: A meta-analysis

Patient-controlled analgesia (PCA) is an effective method of postoperative pain, there have been many studies performed that have compared the efficacy of hydromorphone with continuous sufentanil. The purpose of this systematic review is to compare the efficacy and safety of hydromorphone and sufentanil.

Seven databases were searched for controlled trials to compare the efficacy and safety of hydromorphone and sufentanil. After selecting the studies, extracting the data, and assessing study quality, the meta-analysis was performed on several of the studies with RevMan 5.3.

Thirteen studies comprised of 812 patients were found. The pain intensity of the hydromorphone group was significantly lower than that of the sufentanil group at 12 hours. With no statistical difference at 24 to 48 hours (MD12 = -1.52, 95% CI [-2.13, -1.97], P <.05). The sedation intensity of the hydromorphone group at 12, 24, and 48 hours were lower than those of the sufentanil group, with no statistical difference (MD12 = -0.03, 95% CI [-0.18, 0.12], P > .05; MD24 = -0.20, 95% CI [-0.42, 0.03], P > .05; MD48 = -0.03, 95% CI [-0.18, 0.11)], P > .05). The PCA requests in the hydromorphone group were less than that in the sufentanil group, and there was no significant difference (RR = -0.20, 95% CI [-1.93,1.53], P > .05). The incidence of adverse events in the hydromorphone group was less than that in the sufentanil group, and there was a statistical difference: (RR = 0.61, 95% CI [0.47,0.79], P < .05).

Compared with sufentanil, PCA with hydromorphone was more effective in relieving pain and PCA requests 12, 24, and 48 hours after operation, and significantly reduced the incidence of adverse events, but it did not have an advantage in sedation intensity.
