Review Meta AnalysisProphylactic Ondansetron for the Prevention of Intrathecal Fentanyl- or Sufentanil-Mediated Pruritis: A Meta-Analysis of Randomized Trials.
Pruritus is a common side effect of intrathecal fentanyl or sufentanil that decreases patient satisfaction and may delay hospital discharge. There are conflicting reports about the efficacy of prophylactic ondansetron in reducing the incidence of pruritus. This meta-analysis aimed to assess the effect of prophylactic ondansetron on the incidence of intrathecal fentanyl- or sufentanil-mediated pruritus and the need for rescue treatment. ⋯ IV 8 mg prophylactic ondansetron does not decrease the incidence of fentanyl- or sufentanil-mediated pruritus but may decrease the need for pruritus rescue medication, particularly in specific subgroups. Randomized trials are needed to confirm these results.

Randomized Controlled Trial Comparative StudyThe Effect of Anesthetic Choice (Sevoflurane Versus Desflurane) and Neuromuscular Management on Speed of Airway Reflex Recovery.
Nonintubated patients receiving sevoflurane have slower protective airway reflex recovery after anesthesia compared with patients receiving desflurane. We asked whether this difference would remain significant among intubated patients receiving rocuronium or whether the impact of variable neuromuscular recovery would predominate and thus minimize differences between anesthetics. ⋯ Compared with sevoflurane, desflurane allowed faster recovery of airway reflexes after anesthesia in intubated patients. Clinical management of neuromuscular block, including full reversal and the use of quantitative TOF, affects airway reflex recovery-an effect that may be at least as profound as the choice of potent inhaled anesthetic.

Multicenter StudyCurrent Use of Pain Scores in Dutch Intensive Care Units: A Postal Survey in the Netherlands.
Pain is a common problem for critically ill patients treated in the intensive care unit (ICU) and can have serious consequences. For this reason, the appropriate recognition and treatment of pain is of extreme importance. However, pain assessment in critically ill patients can be challenging because these patients are often unable to self-report. To identify attitudes and practices regarding the assessment and management of pain in ICU patients unable to self-report, we surveyed all adult ICUs in the Netherlands. ⋯ In the Netherlands, most ICUs used a standardized pain score in patients able to self-report. Nonteaching hospitals used pain assessment tools more often than teaching hospitals. In patients unable to self-report, pain is not routinely measured with a validated behavioral pain assessment tool. Almost all nurses in our survey felt that their assessment of patient pain was more accurate than behavioral pain assessment tools in patients unable to self-report. More research is needed to identify factors preventing more widespread acceptance of validated behavioral pain scores in patients unable to self-report.

ReviewUnraveling Interactions Between Anesthetics and the Endothelium: Update and Novel Insights.
The vascular endothelium is one of the largest organs in the body and consists of a single layer of highly specialized cells with site-specific morphology and functions. Endothelial cells play a vital role in the regulation of vascular tone in arterial, venous, microvascular, and lymphatic vascular beds. The endothelium also coordinates angiogenesis and controls cell adhesion, fluid homeostasis, and both innate and adaptive immunity. ⋯ Finally, there is experimental evidence to suggest important effects of anesthetics on the regulation of vascular permeability, proliferation of stem cells, including endothelial progenitor cells, and promotion or inhibition of tumor growth, potentially related to alterations in angiogenesis. However, most of these findings are from in vitro experiments and await confirmation in an in vivo setting. Thus, the clinical implications of these interactions remain uncertain.
