Randomized Controlled TrialA study of low-dose S-ketamine infusion as "preventive" pain treatment for cesarean section with spinal anesthesia: benefits and side effects.
Attenuation of central sensitization with NMDA-active drugs such as S-Ketamine may play a role in postoperative analgesia and prevention of neuropathic pain. However, during cesarean section with neuraxial block, S-Ketamine might have adverse effects on the interaction between mothers and infants, including breastfeeding. ⋯ Preventive administration of S-Ketamine via 12-hour infusion was safe and may have anti-hyperalgesic action after cesarean section.

Non-invasive ventilation (NIV) is increasingly used in patients with acute respiratory failure, but few data exist regarding current sedation practices during NIV. Mask intolerance or claustrophobia, and delirium and agitation, may lead to NIV failure, requiring endotracheal intubation. Judicious use of sedation during NIV could be one of the valuable options for some of these patients at risk of intubation. ⋯ Pilot studies suggest that continuous infusion of a single sedative agent may decrease patient discomfort, with no significant effects on respiratory drive, respiratory pattern, or hemodynamics. In addition, gas exchange improved under NIV with sedation. While the current limited data available suggests that sedation during NIV is safe and feasible, more widespread application should await the results of randomized clinical trials.

ReviewProcalcitonin and sepsis: recent data on diagnostic utility prognostic potential and therapeutic implications in critically ill patients.
Procalcitonin (PCT) has emerged as the most specific biomarker for bacterial infection. As clinicians become more familiar with its use, a multitude of observational studies have reported on its diagnostic potential in distinct types of infections and various clinical situations, such as in neutropenia or in the postoperative period. In the Intensive Care Unit setting, however, the prognostic value of a single PCT measurement at the time of admission on a patient with sepsis is suboptimal. ⋯ The most recent significant development in the field of PCT monitoring, is the publication of several randomized controlled trials that investigated its use as a decision making tool for the initiation and/or the duration of antibiotic treatment. Currently, the available evidence suggests that the incorporation of PCT measurements to assist with the duration of antibiotic stewardship programs may decrease antibiotic use without compromising clinical outcomes. Nevertheless, this strategy still needs further validation in large prospective studies.

Little is known about current use of neuromuscular blocking agents by Italian anesthetists. This paper reports the results of a survey conducted to obtain information about current management of neuromuscular block in Italy. ⋯ Clinical signs are used by most of the Italian anesthetists to assess the recovery from neuromuscular blockade. There is poor awareness about their inability to indicate even a significant degree of residual neuromuscular block. A more extensive use of quantitative instrumental monitoring is required for the more rational use of neuromuscular blocking agents.
