Pain is a challenging area to understand for any healthcare professional, and quality training on the subject is required if nurses are to provide effective pain management and person-centred care. Based on the curriculum developed by the International Association for the Study of Pain, this book offers an essential guide to managing pain. It begins with an examination of the biology of pain, and then goes on to consider pain management across the lifecourse, looking at key topics including acute pain, cancer pain and pharmacology. Case scenarios are included throughout the book to help readers apply the knowledge they have learned to their own practice.It will be valuable reading for undergraduate nurses, and essential for those taking continuing professional development and postgraduate courses in pain management.
