Comparison of Analgesic Effects and Adverse Events of Hydromorphone PCIA Versus Sufentanil PCIA: A Retrospective Analysis

Purpose

The aim of this study was to compare the analgesic effect and adverse events of hydromorphone patient-controlled intravenous analgesia (PCIA) without background dose versus sufentanil PCIA with background dose in patients after surgery.

Design

A retrospective analysis.

Methods

From June 2020 to May 2021, 1,594 eligible postoperative patients who received PCIA were included in this study. According to the types of opioids, patients were divided into two groups: the sufentanil group and the hydromorphone group. The Numerical Rating Scale, Functional Activity Scale, and Level of Sedation were used to evaluate the analgesic effects between the two groups. In addition, total patient-controlled analgesia (PCA) use, effective number of PCA compressions, and adverse effects of PCIA were compared between the two groups.

Findings

At 24 hours (h) after surgery, the Functional Activity Scale score in the sufentanil group was higher than that in the hydromorphone group (P < .05). Compared with the sufentanil group, total PCA use, total number of PCA compressions and effective number of PCA consumptions were significantly decreased in the hydromorphone group during a 48 hours period (P < .05). There were no statistical differences in Numerical Rating Scale score, Level of Sedation score, and adverse events between two groups at 24 hours and 48 hours after surgery.

Conclusions

Compared with sufentanil PCIA with a background dose, under a similar analgesic effect, hydromorphone PCIA without a background dose provided lower PCA use. Our findings may provide useful evidence for more future studies related to postoperative analgesia.
