Sedation before nerve block significantly increases false-positive results, shows study

New research suggests that sedating patients before a nerve block needed to diagnose or treat chronic pain increases costs, risks and unnecessary surgeries, and sedation does nothing to increase patient satisfaction or long-term pain control.

Study reveals nearly 1 in every 100 anesthesiologist developed substance use disorder during training

According to a study conducted by Mayo Clinic and the American Board of Anesthesiology (ABA), nearly 1 in every 100 anesthesiology residents entering primary training from 1975 to 2009 developed substance use disorder (SUD) during training.

TopPac® 20 ml prefillable polymer syringe for infusion therapy introduced by SCHOTT

SCHOTT expanded its range of TopPac polymer syringes to include a 20 milliliter (ml) format that can be used in combination with syringe pumps for infusion therapy. SCHOTT TopPac® prefillable syringes (PFS) simplify the infusion therapy preparation process and can ultimately reduce costs for pharmaceutical companies and health care facilities.

MGH researchers identify probable mechanism for pain-induced cognitive impairment

The pain caused by a surgical incision may contribute to the risk of postoperative cognitive dysfunction, a sometimes transient impairment in learning and memory that affects a small but significant number of patients in the days following a surgical procedure.

Study: Liposomal bupivacaine can provide longer-lasting nerve blocks

Can a new liposomal bupivacaine product provide long-lasting nerve block with a single injection? An initial study in humans shows promise-but also some "confusing results," reports the November issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Less-healthy patients more prone to recovery room complications

Complications in the recovery room decreased by 58 percent between 1990 and 2010, according to a study presented at the ANESTHESIOLOGY 2013 annual meeting. In a previous study completed in the late 1980s, recovery room complications occurred in 23.7 percent of the patients.

New study on propofol drug may help develop effective anesthetics with fewer side effects

Researchers at Washington University School of Medicine in St. Louis and Imperial College London have identified the site where the widely used anesthetic drug propofol binds to receptors in the brain to sedate patients during surgery.

Research: Steroids in spinal shots may not provide relief from lower back pain

New research from Johns Hopkins suggests that it may not be the steroids in spinal shots that provide relief from lower back pain, but the mere introduction of any of a number of fluids, such as anesthetics and saline, to the space around the spinal cord.

Longer time sevoflurane preconditioning does not grant better neuroprotective effects, says study

Sevoflurane belongs to volatile anesthetics, and preconditioning with sevoflurane has been shown to exert protective effects against ischemic injury in the brain. But the mechanism is unclear.

Researchers explore distinctions between natural sleep and anesthetic unconsciousness

Falling asleep in your bed at night and being "put to sleep" under general anesthesia - as well as waking up in the morning or coming out of anesthesia - aren't quite the same thing, yet they share some important similarities. Max Kelz, MD, PhD, assistant professor of Anesthesiology and Critical Care at the Perelman School of Medicine at the University of Pennsylvania, along with colleagues from Penn, UCSD, Howard Hughes Medical Institute, and Thomas Jefferson University, explored the distinctions between anesthetic unconsciousness and sleep by manipulating the genetic pathways known to be involved in natural sleep and studying the resulting effects on anesthetic states.

SmartTots announces recipients of pediatric anesthesia research grants

SmartTots announces Lena Sun, MD and Jeffrey William Sall, PhD, MD as the recipients of its 2013/2014 round of pediatric anesthesia research grants. The research grants are intended to support investigations into the existence of a clinical signal suggesting poor neurocognitive outcomes as the result of early exposure to anesthesia.

Laughing gas is associated with increased risk for perioperative cardiac events

A clinical trial published in the July issue of Anesthesiology may shed some light on whether nitrous oxide ("laughing gas") causes an increased risk for cardiac events, including heart attacks after surgery, particularly among high-risk patients.

Use of longer-acting anesthetic shows no difference in duration of hospitalization

The use of a less-expensive, longer-acting anesthetic (isoflurane) resulted in no difference in duration of hospitalization compared to the use of a more expensive, shorter-acting anesthetic (desflurane or sevoflurane), according to a study from the July issue of Anesthesiology.

Nitrous oxide does not increase heart attack risk, study finds

Nitrous oxide - best known as laughing gas - is one of the world's oldest and most widely used anesthetics. Despite its popularity, however, experts have questioned its impact on the risk of a heart attack during surgery or soon afterward. But those fears are unfounded, a new study indicates.
