There are significant misunderstandings about the management of perioperative do-not-resuscitate orders. This paper reviews some of the difficulties generated by the halting acceptance and inconsistent implementation of an ethically appropriate perioperative do-not-resuscitate policy that mandates reconsideration of existing do-not-resuscitate orders. It also offers strategies for empowerment of such a policy. ⋯ A well written perioperative do-not-resuscitate policy is essential for surmounting obstacles to a well functioning perioperative do-not-resuscitate system.

The purpose of this current opinion on sacroiliac joint pain and dysfunction is to assist interventional pain physicians to apply appropriate treatment decisions and rationale to their patients in pain. Discussion of relevant scientific data and controversial positions will be provided. ⋯ Discussion will provoke support or criticism of the relevant scientific data, and general recommendations for interventional pain management physicians should be considered within the context of the individual practitioners skill and practice patterns. Current Opinion is not intended to provide a standard of care.

The present overview describes recent contributions to the literature with regard to choice of anesthetic techniques, approaches to anesthetic management of elderly outpatients undergoing arthroscopy and other procedures, reconsideration of the problem of postoperative delirium in the elderly patient, and a general summary of perioperative management and assessment of anesthetic risk in older adults. ⋯ The efficiency and speed with which outpatient surgery and anesthetic recovery can be conducted in older adults continue to improve. Monitors of depth of anesthesia, ultra-short-acting agents, and combined techniques have minimized minor complications such as nausea and vomiting, and have improved the speed with which these patients recover from anesthesia. A small proportion of elderly surgical outpatients remain at risk for residual postoperative cognitive dysfunction.

Development of new drugs and special techniques, as well as changes in health care organization have markedly influenced the use of spinal block and its indications. The present review overviews recent developments in local anesthetic drugs, side effects and special techniques for intrathecal anesthesia. ⋯ The changes in health care organization observed during the past few years have forced us to change the indications for and clinical uses of intrathecal anesthesia techniques in accordance with the changing needs of surgery. The development of new drugs and special techniques for spinal anesthesia will further improve the clinical use of this old but trusted technique.

Naturally occurring opiates (endorphins) diminish testosterone levels by inhibiting both hypothalamic gonadotrophin releasing hormone production and testicular testosterone synthesis. Heroin addicts treated with a single daily dose of methadone and nonaddicts receiving continuous intrathecal opioids quickly develop low luteinizing hormone and total testosterone levels. A similar pattern was sought in men consuming commonly prescribed oral opioids. ⋯ Either TT or E(2) level was subnormal in all 28 men consuming the equivalent of 100 mg of methadone daily and in 19 of 26 (73%) consuming smaller opioid doses. Eighty-seven percent (39 of 45) of opioid-ingesting men who reported normal erectile function before opioid use reported severe erectile dysfunction or diminished libido after beginning their opioid therapy. Commonly prescribed opioids in sustained-action dosage forms usually produce subnormal sex hormone levels, which may contribute to a diminished quality of life for many patients with painful chronic illness.
