Major dopamine system helps restore consciousness after general anesthesia, study finds

Researchers may be one step closer to better understanding how anesthesia works.  A study in the August issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), found stimulating a major dopamine-producing region in the brain, the ventral tegmental area (VTA), caused rats to wake from general anesthesia, suggesting that this region plays a key role in restoring consciousness after general anesthesia.  Activating this region at the end of surgery could provide a novel approach to proactively induce consciousness from anesthesia in surgical patients, researchers say.

Surgical patients more likely to follow medication instructions when provided a simple, instruction sheet, study finds

A study in the July issue of Anesthesiology revealed that patients who receive a simple, multicolor, standardized medication instruction sheet before surgery are more likely to comply with their physician’s instructions and experience a significantly shorter post-op stay in recovery. These findings are important because surgical patients often fail to follow their doctor’s medication instructions for preexisting conditions such as diabetes and hypertension on the day they are having surgery – a costly mistake that can lead to surgery cancellation, complications and longer hospital stays.

Researchers identify new compound to treat depression

There is new hope for people suffering from depression.  Researchers have identified a compound, hydroxynorketamine (HNK), that may treat symptoms of depression just as effectively and rapidly as ketamine, without the unwanted side effects associated with the psychoactive drug, according to a study in the July issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®).  Interestingly, use of HNK may also serve as a future therapeutic approach for treating neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases, the authors note.

Surgical safety checklists significantly reduce post-op complications, new review finds

Patients experience fewer postoperative complications when a surgical safety checklist is used by their surgical team, reports the first large-scale review on the subject published in the June issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®). By following a simple checklist, health care providers can minimize the most common postoperative risks such as wound infection and blood loss.

For frail, high-risk seniors, surgery decisions should be patient-centered, team-based and physician-led

Surgery for frail, senior citizen patients can be risky. A new patient-centered, team-based approach to deciding whether these high-risk patients will benefit from surgery is championed in an April 10 Perspective of the New England Journal of Medicine. The Perspective suggests that the decision to have surgery must balance the advantages and disadvantages of surgical and non-surgical treatment as well as the patient’s values and goals in a team-based setting that includes the patient, his or her family, the surgeon, the primary care physician and the physician anesthesiologist.

85 Percent of Heart Attacks and Injuries After Surgery Go Undetected Due to Lack of Symptoms

Without administering a simple blood test in the first few days after surgery, 85 percent of the heart attacks or injuries patients suffer could be missed, according to a study in the March issue of Anesthesiology. Globally, more than 8 million adults have heart attacks or injuries after surgery every year, and 10 percent of those patients die within 30 days.

Research reveals doctors in training want real-time feedback

Anesthesiology residents want frequent feedback on their clinical performance, as well as evaluations of their performance compared to their fellow residents as a whole, according to a study in the January issue of Anesthesiology. The study conducted by faculty in the Vanderbilt University School of Medicine demonstrates how an automated case evaluation tool can fulfill some of the new assessment requirements in the Milestones system of the Accreditation Council for Graduate Medical Education (ACGME), which begins in July 2014 for all anesthesiology residencies.
