Obese, Asthmatic Kids Need Special Care Under Anesthesia

Posted 19 Oct 2011 by Drugs.com

WEDNESDAY, Oct. 19 – Obese children need special attention when they undergo anesthesia, two new studies suggest. In one study, researchers found that obese children with asthma suffer more complications from anesthesia than normal weight children with asthma. In the other study, researchers found that obese children require less of one type of anesthesia than normal weight kids. If a child is obese, has asthma or both, parents should expect close monitoring, said researcher Dr. Olubukola Nafiu, an assistant professor of pediatric anesthesiology at the University of Michigan. "Children who are obese and asthmatic have a twofold increased risk of developing respiratory problems when they are given anesthesia," Nafiu said. Both studies are scheduled for presentation Monday at the annual meeting of the American Society of Anesthesiologists in Chicago. To determine if complications were ... Read more

General Anesthesia Does Not Boost Cancer Risk, Study Finds

Posted 3 Oct 2011 by Drugs.com

MONDAY, Oct. 3 – Among patients given general anesthesia for surgery, the length or depth of sedation was not linked to an increased risk of developing cancer within five years of the operation, Swedish researchers report. "Neither duration of anesthesia nor increased cumulative time with profound sevoflurane anesthesia was associated with an increased risk for new malignant disease within five years after surgery in previously cancer-free patients," study author Maj-Lis Lindholm, of the Karolinska Institute in Stockholm, concluded in a news release from the International Anesthesia Research Society. In conducting the study, researchers looked at data on almost 3,000 cancer-free Swedish surgical patients who were given sevoflurane – one of the most widely used inhaled anesthetics. The news release said other studies have raised the theory that anesthesia might reduce immune responses ... Read more

Could Surgery, Anesthesia While Very Young Hamper Kids' Development?

Posted 3 Oct 2011 by Drugs.com

MONDAY, Oct. 3 – Children younger than 2 who undergo multiple surgeries requiring general anesthesia may be up to three times more likely than other children to develop speech and language problems as they grow up, a new study suggests. However, experts cautioned that the finding appears to be restricted to very small children who require more than one surgery. "A single exposure to anesthesia in surgery has not been shown to be problem, so parents can be reassured that this is not likely to cause any problems," said study author Dr. Randall Flick, an associate professor of anesthesiology and pediatrics at the Mayo Clinic in Rochester, Minn. "For children who have or will have repeated exposures to anesthesia, it's important that those families have a conversation with the surgeon and anesthesiologist to determine the risks and benefits in a broad context." The new findings are ... Read more

No Long-Term Effects Seen From Anesthesia in Infancy

Posted 29 Apr 2011 by Drugs.com

WEDNESDAY, April 27 – Exposing young children to a brief, single anesthetic does not seem to cause long-term harmful effects on the brain, a finding that should reassure parents, researchers say. Previous studies in young animals have found evidence that anesthetics can cause developmental and behavioral problems, but whether the same is true in young children has been uncertain. In this new study, researchers compared the academic performance of two groups of ninth-grade students in Denmark: 2,689 who had inguinal hernia repair before they were 1 year of age, and 14,575 in the general population. There was no statistically significant difference in academic performance between the two groups, and the majority of students who had hernia repair in infancy showed no signs of neurological impairment, the investigators found. The study is published in the May issue of the journal ... Read more

When Given Control, Women Use Less Epidural Anesthesia During Delivery

Posted 10 Feb 2011 by Drugs.com

THURSDAY, Feb. 10 – If women are given control of the amount of epidural anesthesia they get during labor and delivery, they use about 30 percent less medication than when given a standard dose from a doctor, a new study shows. "We looked at patient-controlled epidural anesthesia, and found the women were basically as comfortable as women on a continuous dose, and there was a 30 percent reduction in the amount of anesthesia used," said study author Dr. Michael Haydon, a perinatologist at Long Beach Memorial Medical Center in California. Haydon is scheduled to present the findings Thursday at the Society for Maternal-Fetal Medicine annual meeting in San Francisco. Research presented at meetings is generally preliminary, experts note, since it has not been subjected to the same rigorous scrutiny as research published in peer-reviewed medical journals. Epidural anesthesia is a common form ... Read more

New Anesthesia May Be Safer for Critically Ill

Posted 23 Jul 2009 by Drugs.com

THURSDAY, July 23 – A new variation of a common general anesthesia has been developed that may be safer for some patients. Preclinical studies done on rats put under with MOC-etomidate, a chemically altered version of the anesthetic etomidate, found the drug does not cause blood pressure to drop suddenly or slow adrenal gland activity, common side effects that can be fatal to the elderly or certain critically ill patients. "We have shown that making a version of etomidate that is broken down very quickly in the body reduces the duration of adrenal suppression while retaining etomidates benefit of keeping blood pressure much more stable than other anesthetics do," study leader Dr. Douglas Raines, of Massachusetts General Hospital's department of anesthesia, critical care and pain medicine, said in a hospital news release. Most general anesthetics cause blood pressure to fall, often ... Read more
