ReviewResidual neuromuscular blockade: management and impact on postoperative pulmonary outcome.
To revise the current literature on concepts for neuromuscular block management. Moreover, consequences of incomplete neuromuscular recovery on patients' postoperative pulmonary outcome are evaluated as well. ⋯ New evidence has emerged about the pathophysiological implications of incomplete neuromuscular recovery. Not only are the pulmonary muscles functionally impaired, but respiratory control is also affected. Residual paralysis endangers the coordination of the pharyngeal muscles and the integrity of the upper airway. However, neuromuscular monitoring and whenever needed pharmacological reversal prevent residual paralysis.

Perioperative prediction models can help to improve personalized patient care by providing individual risk predictions to both patients and providers. However, the scientific literature on prediction model development and validation can be quite technical and challenging to understand. This article aims to provide the necessary insight for clinicians to assess the value of a prediction model that they intend to use in their clinical practice. ⋯ Clinicians can assess the value of a prediction model for their practice by first identifying what the usage of the model will be. Second, they can recognize which performance characteristics are relevant to their assessment of the model. Finally, they need to decide whether the available scientific evidence sufficiently matches their clinical practice to proceed with implementation.

Needle-based and cannula-based eye blocks are 'blind' techniques prone to rare but serious complications. Ultrasound, an established adjunct for peripheral nerve block, may be beneficial for ophthalmic anesthesia application. The present review details the evolution of ultrasound-guided eye blocks, outlines safety issues, and reviews recent studies and editorial opinions. ⋯ Ultrasound-guided ophthalmic regional anesthesia is evolving beyond simple visualization of the anatomy. Recent research emphasizes the imprecision of needle tip location without ultrasound and the key role of imaging local anesthetic dispersion. There is ongoing debate in the literature regarding the utility of routine ultrasound for eye blocks.

ReviewAssessing the value of risk indices of postoperative nausea and vomiting in ambulatory surgical patients.
Postoperative and postdischarge nausea and vomiting have profound impact on the efficient delivery of quality healthcare. In addition to patient dissatisfaction, physical morbidities as well as unplanned hospital admissions may result. It is important to risk stratify and intervene on patients at risk. The aim of this review is to explore the benefits and shortcomings of the scoring systems commonly used today. ⋯ Risk-stratifying scoring systems seek to identify patients at risk for postoperative/postdischarge nausea and vomiting. A protocol-based approach is recommended. A number of risk stratification systems have been validated and have been simplified for widespread adoption. Some institutions report a decrease in postoperative nausea and vomiting rates when an algorithm is followed based on one of the three scoring systems. By identifying at risk patients, an anesthetic can be better planned. A reduction in the incidence of postoperative/postdischarge nausea and vomiting will have a direct effect upon patient satisfaction, morbidity, and healthcare costs.
