Patient-controlled analgesia for the management of adults with acute trauma in the emergency department: A systematic review and meta-analysis.

Abstract

BACKGROUND:

Patient-controlled analgesia (PCA) has potential as a form of analgesia for trauma patients in the emergency department (ED). The objective of this review was to evaluate the effectiveness and safety of PCA for the management of adults with acute traumatic pain in the ED. The hypothesis was that PCA can effectively treat acute trauma pain in adults in the ED, with minimal adverse outcomes and better patient satisfaction compared with non-PCA modalities.

METHODS:

MEDLINE (PubMed), Embase, SCOPUS, ClinicalTrials.gov , and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from inception date to December 13, 2022. Randomized controlled trials involving adults presenting to the ED with acute traumatic pain who received intravenous (IV) analgesia via PCA compared with other modalities were included. The Cochrane Risk of Bias tool and the Grading of Recommendation, Assessment, Development, and Evaluation approach were used to assess the quality of included studies.

RESULTS:

A total of 1,368 publications were screened, with 3 studies involving 382 patients meeting the eligibility criteria. All three studies compared PCA IV morphine with clinician-titrated IV morphine boluses. For the primary outcome of pain relief, the pooled estimate was in favor of PCA with a standard mean difference of -0.36 (95% confidence interval, -0.87 to 0.16). There were mixed results concerning patient satisfaction. Adverse event rates were low overall. The evidence from all three studies was graded as low-quality because of a high risk of bias from lack of blinding.

CONCLUSION:

This study did not demonstrate a significant improvement in pain relief or patient satisfaction using PCA for trauma in the ED. Clinicians wishing to use PCA to treat acute trauma pain in adult patients in the ED are advised to consider the available resources in their own practice settings and to implement protocols for monitoring and responding to potential adverse events.
