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.

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.

Angioneurotic oedema is a rare disease caused by Cl esterase inhibitor deficiency. Hereditary angioneurotic oedema includes type I (quantitative and functional) deficiency and type 11 (functional) deficiency. Its prophylactic treatment during pregnancy, based on danazol therapy if the fetus is male, may avoid acute attacks of generalized or laryngeal oedema. ⋯ Regional analgesia is indicated for labour or caesarean section to prevent pain and stress and to avoid the difficulties associated with laryngeal oedema and tracheal intubation. In the treatment of an acute attack, Cl esterase inhibitor concentrates (1500 units) may be given i.v. We present two cases, one of hereditary and one of acquired angioneurotic oedema, both presenting during pregnancy and both delivered vaginally under epidural analgesia with successful outcome.

To consider the evidence for the beneficial effects of the current management guidelines in traumatic brain injury, and to highlight the important issues. ⋯ The impact of management guidelines in traumatic brain injury on patient outcome has been difficult to determine. However, there is a large body of uncontrolled evidence that suggests secondary global cerebral ischaemia-hypoxic insults are the major determinants in influencing outcome and that therapeutic interventions that maintain and defend cerebral perfusion pressures may improve outcome.

To review the recent advances in ventilatory therapy for acute respiratory failure in children. ⋯ High frequency ventilation exists in three forms, although only high frequency oscillation appears to show any benefit in the management of acute respiratory failure refractory to conventional mechanical ventilation. Extracorporeal oxygenation has halved mortality in neonates with acute respiratory failure, and has been used successfully in non-neonate patients. Inhaled nitric oxide from 6 to 20 parts per million improves oxygenation in paediatric patients with acute respiratory failure and congenital heart disease (particularly in the presence of pulmonary arterial hypertension). Liquid ventilation or perfluorocarbon-associated gas exchange has also been used to treat acute respiratory failure in paediatric patients, with partial liquid ventilation particularly appearing to show promise.
