Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled analgesia compared with nurse-controlled infusion analgesia after heart surgery.
A randomized, controlled clinical trial was conducted on 66 patients undergoing elective cardiac surgery to compare patient-controlled analgesia (PCA) to nurse-controlled analgesia (NCA) with continuous morphine infusion. Hourly assessment of pain (at rest and on movement) using a visual analogue scale (VAS), of respiratory rate, and level of sedation took place for the 24 h following extubation. The incidence of nausea was also recorded. ⋯ The PCA group also consumed significantly more morphine (P = 0.0001). The study suggests a beneficial effect from PCA after cardiac surgery in reducing nausea, compared to NCA. It confirms nurse-controlled infusion analgesia as an effective form of pain relief in an intensive care and high-dependency setting.

ReviewFocus of nursing in critical and acute care settings: prevention or cure?
The fluidity of the boundaries of critical and acute care can lead to challenges for nurses working on acute general wards when caring for post-critical care patients and for those in whom a critical care situation arises during a period of acute care. The development and use of critical care skills pose special difficulties for acute care nurses, because of the acuteness and infrequency of such incidents and the diversity of skills the nurses need to possess. Nonetheless, critical care is an important component of an acute ward nurse's repertoire, particularly in relation to preventing episodes of critical illness. ⋯ They may, in addition, lead to an over-reliance on the use of such facilities and must be implemented carefully in order to bridge, rather than widen, the gap between acute and critical care. Critical care is used in this paper as a global term, to encompass all settings where patients are usually more highly dependent and critically ill than patients on general wards. It includes intensive therapy, high-dependency, coronary care and other specialist critical care units.
