The most recent advances in the field of epidural analgesia are described in this book. Epidural analgesia is a type of pain relief process managed through the space encircling the dural sheath either by direct injection or through catheter. The agent, when executed, can cause both a loss of sensation (anesthesia) and redemption of pain (analgesia), by reversibly interrupting the transmission of signals through nerves in or near the spinal cord. This form of pain relief has been found effective in many clinical situations. This book provides a detailed review of the contemporary knowledge on epidural analgesia. The use of this form of analgesia has been explored by authors from diverse points of view, including labor and delivery, postoperative analgesia in both pediatric and geriatric patients and its role during anesthesia and surgery. With an aim to provide a comprehensive medical view, this book has been edited by a veteran in the field of contemporary medical science.
