Opioids are effective analgesics, but they can have harmful adverse effects, such as addiction and potentially fatal respiratory depression. Naloxone is currently the only available treatment for reversing the negative effects of opioids, including respiratory depression. ⋯ Long-acting opioids, and those with a high affinity at the µ-opioid receptor and/or slow receptor dissociation kinetics, are particularly resistant to the effects of naloxone. In this review, the authors examine the pharmacology of naloxone and its safety and limitations in reversing opioid-induced respiratory depression under different circumstances, including its ability to prevent cardiac arrest.

Control of Breathing Using an Extracorporeal Membrane Lung. By T Kolobow, L Gattinoni, TA Tomlinson, JE Pierce. Anesthesiology 1977; 46:138-41. ⋯ A unique opportunity for research was the spontaneous birth of a network of scientists who became friends in the European Group of Research in Intensive Care Medicine. In this environment, it was possible to develop core concepts such as the "baby lung" and to understand the mechanisms underlying computed tomography-density redistribution in the prone position. Physiology guided us in the 1970s, and understanding mechanisms remains of paramount importance today.

Providing continuous health insurance coverage during the perinatal period may increase access to and utilization of labor neuraxial analgesia. This study tested the hypothesis that implementation of the 2010 Dependent Coverage Provision of the Patient Protection and Affordable Care Act, requiring private health insurers to allow young adults to remain on their parent's plan until age 26 yr, was associated with increased labor neuraxial analgesia use. ⋯ Implementation of the Dependent Coverage Provision was associated with a statistically significant increase in labor neuraxial analgesia use, but the small effect size is unlikely of clinical significance.
