In this review, we attempted to summarize the effectiveness and the limitation of end-tidal carbon dioxide monitoring during cardiopulmonary resuscitation. End-tidal carbon dioxide can be an indicator of the real return of spontaneous circulation and can also be an indicator of the effectiveness of cardiac massage. We cannot, however, estimate the prognosis of cardiopulmonary resuscitation from the end-tidal carbon dioxide value. We concluded that cardiopulmonary resuscitation should never be abandoned for the sole reason that the end-tidal carbon dioxide value is low.

Health care delivery is undergoing a revolutionary change. It is focusing rapidly all over the world towards outpatient and home care. One of the most obvious results of these changes has been the relative explosion office-based surgery and anesthesia; however, these are not new concepts. ⋯ These guidelines should be based on the specific type of surgery, the level of anesthetic required and the design of the office. This way the provision of adequate quality of care is ensured. Office-based anesthesia and surgery will no doubt continue to evolve because it is safe, pleasing and convenient for the patient and of low cost.

Recent advances in the application of regional anesthesia to the care of patients undergoing shoulder surgery are discussed. New techniques for the management of postoperative pain are highlighted, with an emphasis on interscalene patient-controlled analgesia and suprascapular block. ⋯ Intraoperative hypotension and bradycardia caused by activation of the Bezold-Jarisch reflex is considered. The ongoing debate regarding the use of paresthesia versus nerve-stimulator techniques is examined.

Anaesthetists who manage acute and chronic pain need to be familiar with current research and practice guidelines in these areas. New local anaesthetics and new routes of administration for opioids and adjuvants may further improve our management of acute pain. ⋯ The limitations of nerve blocks are acknowledged and guidelines for managing chronic pain and opioids are available. Anaesthetists must recognize psychological difficulties as a significant perpetuating factor in chronic pain.
