Randomized Controlled Trial
Locked out and still knocking: predictors of excessive demands for postoperative intravenous patient-controlled analgesia.
Psychosocial factors governing the use of postoperative, intravenous patient-controlled analgesia (PCA) have received little attention in spite of the fact that PCA is the most common modality for managing pain after surgery. The motivation behind requests for analgesia during lockout periods is not known. Unrelieved pain and need for pain medication are obvious reasons but other factors may be involved. The aim of the present study was to predict PCA lockout interval demands based on preoperative psychosocial factors. ⋯ Excessive demands for postoperative intravenous- PCA morphine during lockout intervals appear to reflect, in part, poor preoperative adaptation to surgery involving intrusive thoughts and avoidant behaviours about the upcoming surgery.

Randomized Controlled Trial
Fibreoptic airway training: correlation of simulator performance and clinical skill.
Simulation centres, where trainees can practise technical procedures on models of varying fidelity, provide a training option that allows them to acquire skills in a controlled environment prior to clinical performance. It has been proposed that the time to complete a simulator task may translate to proficiency in the clinical setting. The objective of this study was to determine whether time to complete a simulator task translates to clinical fibreoptic manipulation (FOM) performance. ⋯ These results suggest that simulator-based, task-orientated time measurement may not be a good indicator of FOI performance in the clinical setting.
