Paravertebral blocks are becoming increasingly popular, especially as an anesthetic adjunct for breast procedures. New reports suggest additional reasons for adding this block to the anesthetic armamentarium. ⋯ Paravertebral blocks are a well established option to provide anesthesia and postoperative analgesia during breast surgery. Recent studies suggest additional benefits to this procedure. Not only is acute pain better controlled, but the development of chronic mastectomy pain syndrome and recurrence of cancer may be reduced by preoperative placement of paravertebral block. These studies provide additional reasons why this block should be considered as part of the anesthetic for breast surgery.

ReviewNon-anesthesiologist-provided pediatric procedural sedation: an update.
This review evaluates the past year's literature on the provision of pediatric procedural sedation outside of the operating room, especially as performed by non-anesthesiologist healthcare providers. ⋯ Pediatric procedural sedation practice as performed by non-anesthesiologists continues to grow. Ongoing efforts to understand the elements of sedation systems that lead to best practice, with the subsequent development of uniform practice approaches, are essential. A collaborative relationship between anesthesiologists and non-anesthesiologist providers of procedural sedation is essential for meeting common goals.

Sugammadex is a novel drug that binds selected neuromuscular blocking drugs and prevents them from acting at the neuromuscular junction. Due to its rapid onset and relative lack of side effects, this drug promises to change the method of anesthesia delivery. This review summarizes the literature on the drug and addresses some of the potential changes that it may bring. ⋯ Sugammadex binds neuromuscular blocking drugs and encapsulates them, making cholinesterase inhibitors unnecessary. Its rapid reversal of blockade makes it possible to keep patients profoundly muscle relaxed until drapes come down and it can enable a rapid return to spontaneous ventilation in a 'cannot intubate, cannot ventilate' situation. Costs and date of availability have yet to be determined.

ReviewBlood substitutes as pharmacotherapies in clinical practice.
To discuss the development and current status of blood substitutes, including hemoglobin-based oxygen carriers (HBOCs) and perfluorocarbons. Research in this field offers an important view into the future of transfusion medicine in the operating room, as well as in trauma and combat arenas. ⋯ Polymerized hemoglobin preparations have proven most successful in clinical trials due to their improved side-effect profile. The goal is to evaluate blood substitutes with enhanced intravascular retention, reduced osmotic activity, and attenuated hemodynamic derangements such as vasoconstriction. Although not without substantial morbidity and mortality, the current safety of allogeneic blood transfusion demands that comparative studies show minimal adverse effects, as well as efficacy and potential for novel applications.

ReviewThe nature of anesthesia and procedural sedation outside of the operating room.
Procedural sedation and monitored anesthesia care have become increasingly common in locations outside of the operating room. The different types of procedures are presented along with pertinent safety issues with the use of different drug combinations. ⋯ The number and types of procedures done outside of the operating room are steadily increasing. Sedation for these is often provided by nonanesthesiologists. A quality assurance system dedicated to track events associated with procedural sedation and anesthesia done outside of the operating room is instrumental for the maintenance of exemplary quality of sedation and safety of our patients.
