This Is Your Brain on Anesthesia: Study Sheds Light on How Brain Reacts During Anesthetic Induction and Emergence

A study presented at this year’s Annual Meeting of the American Society of Anesthesiologists strengthens emerging evidence that the act of going under anesthesia and coming out of anesthesia are distinct neurobiological processes. It also found that the parietal region of the brain may play a critical role in how anesthesia suppresses consciousness.

Research Shows a Woman’s Ethnicity and Genetics Can Impact Labor Progression and Pain

Results from a clinical study presented at ANESTHESIOLOGY 2010 suggest that a women’s labor experience is tied to her ethnicity as well as genetics.

Surgery in Infants and Young Children Heightens Neurodevelopmental Risk

When children undergo anesthesia during surgery, the long-term effects that anesthetics have on the developing brain is relatively unknown. A study presented at this year’s American Society of Anesthesiologists Annual Meeting assesses the association between exposure to anesthesia in children 3 years old and younger and their risk for developmental and behavioral disorders.

Studies Reveal a Need to Identify and Implement a Screening Procedure for Obstructive Sleep Apnea Prior to Surgery

As Americans get heavier and heavier, the incidence of obstructive sleep apnea increases, and results from two clinical studies presented at ANESTHESIOLOGY 2010 reinforce the need for physicians to screen for the disorder prior to surgery in order to appropriately manage the patient in the operating room.

Mayo Clinic Finds Early Success with Laser That Destroys Tumors with Heat

Physicians at Mayo Clinic’s Florida campus are among the first in the nation to use a technique known as MRI-guided laser ablation to heat up and destroy kidney and liver tumors. So far, five patients have been successfully treated — meaning no visible tumors remained after the procedure.

Surface Electromyography Can Maximize Physical Therapy for Knee Surgery Patients

Following knee surgery, fear of pain and reinjury can inhibit recovery. Patients who experience chronic pain and disability may avoid physical activity and develop deconditioning syndrome—decreased muscle strength and range of motion, and even weakness of the cardiovascular system. Surface electromyography (SEMG) biofeedback training, in conjunction with rehabilitation efforts, can assist the postoperative recovery process by helping patients reduce or overcome muscle inhibition. This can achieve increased strength and range of movement, along with a return to more normal functioning of the knee.

Rates of Blood Transfusions For CABG Surgery Varies Widely Among U.S. Hospitals

A study that includes data on more than 100,000 patients who underwent coronary artery bypass graft surgery finds that there is wide variability among hospitals in the U.S. on the use of blood transfusions, without a large difference in the rate of death, suggesting that many transfusions may be unnecessary, according to a study in the October 13 issue of JAMA.

Restrictive Use of Blood Transfusions During Cardiac Surgery Shows Comparable Outcomes

Use of stricter guidelines for the use of red blood cell transfusions for patients undergoing cardiac surgery was associated similar rates of death and severe illness compared to patients who received more transfusions, according to a study in the October 13 issue of JAMA.

Long-Lasting Mechanical Heart Device Implanted for the First Time in Canada in Advanced Heart Failure Patient

In a Canadian first, the Peter Munk Cardiac Centre used a new kind of left ventricular assist device (LVAD) to treat a patient with advanced heart failure. The new device is longer lasting than older generation LVADs and may eliminate the need for a second LVAD – a major drawback with the old technology.

Carotid Stents Linked With Greater Risk of Stroke or Death Than Carotid Endarterectomy Surgery

For patients with blockages in the carotid artery that supplies blood to the brain, carotid artery stenting (a non-surgical treatment) appears to be associated with an increased risk of both short- and long-term adverse outcomes when compared with surgical treatment (carotid endarterectomy), according to a meta-analysis of previously published studies that was posted online today and will appear in the February 2011 print issue of Archives of Neurology, one of the JAMA/Archives journals.
