Influential factors of postoperative pain trajectories in patients receiving intravenous patient-controlled analgesia: a single-centre cohort study in Taiwan.

ABSTRACT: OBJECTIVES:We aimed to investigate the factors associated with variations in postoperative pain trajectories over time in patients using intravenous patient-controlled analgesia (IV-PCA) for postoperative pain. DESIGN:Retrospective cohort study. SETTING:A single medical centre in Taiwan. PARTICIPANTS:Patients receiving IV-PCA after surgery. PRIMARY AND SECONDARY OUTCOME MEASURES:Primary outcome was the postoperative pain scores. RESULTS:A total of 3376 patients and 20 838 pain score observations were analysed using latent curve models. Female and longer anaesthesia time increased the baseline level of pain (p=0.004 and 0.003, respectively), but abdominal surgery and body weight decreased it (both p<0.001). Regarding the trend of pain resolution, lower abdominal surgery steepened the slope
