Pain solution in the emergency setting (pasties); an open-label randomised trial of patient-controlled analgesia (pca) versus routine care in patients attending the emergency department with traumatic injuries.

Patient controlled analgesia (PCA) is used in other hospital settings but there is little evidence to support its use in emergency patients. This study (one of two parallel trials) aimed to assess the effectiveness and cost-effectiveness of PCA in emergency patients with traumatic injuries
