To discuss the reasons why 250 ml 7.5% hypertonic saline was chosen as a pre-hospital resuscitation fluid for head injured patients in a multicentred, prospective, randomised controlled trial investigating its long term effects on central nervous system outcome. ⋯ Pre-hospital resuscitation of head injured and hypotensive trauma patients using hypertonic saline, has the potential to reduce long term cerebral injury and reduce social and financial costs to the community.

To determine whether the addition of intravenous dexamethasone to standard emergency department (ED) migraine therapy would decrease the incidence of severe recurrent headache 24 to 48 hours after initial treatment. ⋯ Migraine recurrence is common after "successful" ED treatment. Inflammation may be a critical factor in migraine genesis. Intravenous dexamethasone decreases the incidence of severe recurrent headache after ED treatment and should be offered to patients thought to be at risk of recurrent headache.

Intrathecal drug delivery improves pain relief, reduces suffering, and enhances quality of life in the small proportion of patients who do not respond well to oral analgesics, including oral morphine. Although morphine is the "gold standard," and the only drug approved for intrathecal pain therapy in the United States, off-label use of alternative agents appears promising, particularly in patients with neuropathic pain. Careful patient selection and management are significant determinants of successful treatment outcomes. ⋯ In addition, all patients (those with cancer or nonmalignant pain) must exhibit a positive response to an epidural or intrathecal screening test. A multidisciplinary team approach, involving psychologists, nurses, physical therapists, social workers, and spiritual leaders should be used to manage patients. Current practices for patient selection and management, screening tests, and dosing guidelines for intrathecal drug delivery systems are discussed.

Intrathecal drug delivery is effective for the treatment of cancer and nonmalignant pain in patients who do not respond well to oral opioids, in patients who cannot tolerate the side effects associated with opioids, or in patients who show a large, permanent increase in dosage. Although intrathecal drug delivery is associated with pharmacological side effects and complications, its benefits far outweigh its risks. There are three main categories of potential adverse events associated with intrathecal drug delivery: pharmacologic side effects, surgical complications, and device-related complications. ⋯ Many adverse events either resolve on their own or can be managed with dosage or device adjustment. More serious complications may require surgical intervention or discontinuation of therapy. This paper will provide an overview of adverse events and complications, their origins, detection, manifestations, and management.

Although opioid therapy has been accepted for the treatment of patients with cancer pain, its use for nonmalignant pain is still regarded as controversial due to concerns about the development of tolerance and psychological dependence. However, recent studies indicate that there is a low incidence of addiction in patients who do not have a history of addictive disorders, and opioid use is increasing for long-term treatment in patients with nonmalignant pain. ⋯ These studies demonstrate that intrathecal opioid delivery produces short-term relief of specific symptoms and improves long-term outcomes such as patient functioning (measured by increases in activities of daily living [ADLs] and capacity to work), mood, treatment satisfaction, and quality of life, as well as decreases in oral opioid use. Furthermore, these studies showed there was no development of tolerance or addiction in patients who received long-term intrathecal opioid delivery.
