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.

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.
