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.

Initial studies suggested that the use of processed electroencephalogram technology could significantly decrease the incidence of unintended intraoperative awareness events during general anesthesia. Subsequent work has cast doubts on these findings. This review will examine the current state of awareness monitoring. ⋯ Although awareness monitors such as the bispectral index monitor may have benefit in patients in whom volatile anesthetic agents must be minimized - such as in hemodynamically unstable patients, or patients undergoing total intravenous anesthesia - these monitors do not appear to be useful for all patients.

ReviewDay surgery regional anesthesia in children: safety and improving outcomes, do they make a difference?
The objective of this review is to provide an overview of recent developments in pediatric regional anesthesia and elucidate outcomes as it relates to patient safety and overall satisfaction. ⋯ Despite the limited number of randomized controlled trials evaluating the safety of individual regional anesthetic techniques, the growing body of data, such as presented in the Pediatric Regional Anesthesia Network database, suggests a high degree of safety in performing various regional anesthetic modalities. Modern medicine should continue to embrace the use of regional anesthesia, particularly in the ambulatory setting, to reduce perioperative pain and improve patient outcomes.

ReviewEnhanced recovery after surgery, perioperative medicine, and the perioperative surgical home: current state and future implications for education and training.
The purpose of this review is to summarize the current state of perioperative medicine, including the perioperative surgical home (PSH) and enhanced recovery after surgery pathways (ERAS) as well as the educational implications of these concepts for current and future anesthesiology trainees. ⋯ There is sufficient evidence to support widespread adoption of ERAS principles, although the specifics of local implementation may vary from site to site. There is significant uncertainty as to what the PSH actually is. However, perioperative medicine is a defined specialty in medicine that overlaps significantly with anesthesiology core training and practice and will be a significant focus in future education, research, and clinical care provided by anesthesiologists.

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.
