New doctoral thesis reveals potential treatment for stress-induced cardiomyopathy

New doctoral thesis reveals potential treatment for stress-induced cardiomyopathy

Stress induced cardiomyopathy after cerebral hemorrhage has been shown to increase the risk of further brain damage. These patients can now be identified by a simple blood test, and a possible treatment for stress induced cardiomyopathy has been discovered - a different kind of anesthesia than that currently being used. A new doctoral thesis at Sahlgrenska Academy has explored these issues. [More]
Combatting viral and bacterial lung infections with volatile anesthetics: an interview with Dr Chakravarthy

Combatting viral and bacterial lung infections with volatile anesthetics: an interview with Dr Chakravarthy

Inhaled anesthetics are fairly common all over the world for minor and extensive surgical procedures in patients of all age groups. In the olden days when anesthesia was first developed, ether was the first inhaled anesthetic. That has been replaced, with the more recent discoveries of sevoflurane, isoflurane, and desflurane.

Brief exposure to general anesthesia during infancy does not affect neurological development

Brief exposure to general anesthesia during infancy does not affect neurological development

Although the medical community has raised concerns about the safety of anesthesia on the developing brains of young children, new research presented at the ANESTHESIOLOGY 2015 annual meeting, found brief exposure to general anesthesia during infancy did not impair neurological development. This is the first prospective, randomized, controlled clinical trial to assess the long-term, neurological effects of anesthesia in children. [More]
Limited use of general anesthesia does not cause developmental problems for children

Limited use of general anesthesia does not cause developmental problems for children

An international team of researchers that includes a pediatric anesthesiologist from the University of Colorado School of Medicine and Children's Hospital Colorado is reporting that limited use of general anesthesia with an infant does not cause developmental problems for the child. [More]
Discovery may provide noninvasive approach to assessing toxic effects of anesthetic agents in children

Discovery may provide noninvasive approach to assessing toxic effects of anesthetic agents in children

Could looking at the eyes provide a new way of studying how anesthesia affects the developing brain? The retinas of immature mice exposed to one widely used general anesthetic show evidence of "programmed cell death," or apoptosis, reports a study in Anesthesia & Analgesia. [More]
Innovative technologies offer hope to people living with chronic pain

Innovative technologies offer hope to people living with chronic pain

More than 100 million people in this country have pain that won't go away. Many of these chronic pain sufferers fail to get relief from pills, shots and even surgery, while others temporarily trade the pain for side effects such as drowsiness or digestive problems. [More]
Repeated exposure to anesthesia early in life causes long-term behavioral changes

Repeated exposure to anesthesia early in life causes long-term behavioral changes

Repeated exposure to anesthesia early in life causes alterations in emotional behavior that may persist long-term, according to a study from the Icahn School of Medicine at Mount Sinai in collaboration with the Yerkes National Primate Research Center, and published in the Online First edition of Anesthesiology, the official medical journal of the American Society of Anesthesiologists.

Volatile anesthetics may combat viral and bacterial infections in the lung

Volatile anesthetics may combat viral and bacterial infections in the lung

In use for more than a century, inhaled anesthetics like nitrous oxide and halothane have made modern surgery possible. Now, in experiments in mice, researchers at Johns Hopkins and elsewhere have added to evidence that certain so-called "volatile" anesthetics -- commonly used during surgeries -- may also possess powerful effects on the immune system that can combat viral and bacterial infections in the lung, including influenza and pneumonia.

Research reveals why older adults who undergo general anesthesia experience postoperative delirium

Research reveals why older adults who undergo general anesthesia experience postoperative delirium

Newly published research from the Department of Geriatrics and Gerontology at the Rowan University School of Osteopathic Medicine explains why up to half of older adults who undergo general anesthesia develop postoperative delirium - the sudden onset of confusion, aggression or agitated behavior that could progress to dementia. The findings indicate that older patients who are undergoing surgery may benefit from a less-potent, slower-acting anesthetic. [More]
MGH papers reveal the way anesthetics affect brains of older patients and children

MGH papers reveal the way anesthetics affect brains of older patients and children

Recent Massachusetts General Hospital (MGH) investigations into the neurobiology underlying the effects of general anesthesia have begun to reveal the ways different anesthetic agents alter specific aspects of the brain's electrical signals, reflected by EEG (electroencephalogram) signatures. While those studies have provided information that may lead to improved techniques for monitoring the consciousness of patients receiving general anesthesia, until now they have been conducted in relatively young adult patients.
