Does General Anesthesia Affect Babies' Brains?

Posted 1 Sep 2017 by Drugs.com

FRIDAY, Sept. 1, 2017 – Babies who receive general anesthesia for surgery before they're 1 year old may have less white matter in their brains, a small study suggests. The researchers said they also found that the integrity, or structure, of the white matter might have been affected. White matter is tissue that connects different parts of the brain. "The most rigorous previous study in humans looked at the effects of general anesthesia during infancy on cognitive [brain] functions of 2-year-olds, and results showed no effect," said study first author Robert Block. He is an associate professor of anesthesia at the University of Iowa Carver College of Medicine. "This study is looking specifically at the white matter structure and how it is affected," Block said in a university news release. The University of Iowa Health Care study included 34 healthy children aged 12 to 15. Half of these ... Read more

A Shot of Caffeine May Speed Wake-Up After Anesthesia

Posted 21 Aug 2017 by Drugs.com

MONDAY, Aug. 21, 2017 – Caffeine may help patients wake up more quickly after general anesthesia, an animal study suggests. Adult rats were given a 3 percent concentration of a general anesthetic for one hour to simulate effects of a brief surgical procedure. During the last 10 minutes of anesthetic exposure, they received an injection of either caffeine or a salt solution (the control group). The experiment was repeated three times with increasingly higher amounts of caffeine. Each time, rats in the caffeine group woke faster than the others. At the highest dose, the rats in the caffeine group woke up 55 percent sooner than the control group. The researchers said caffeine appears to shorten anesthesia recovery time in two ways. Caffeine boosts levels of cyclic adenosine monophosphate (cAMP), a compound that regulates cell function. Previous studies have found an increase in cAMP ... Read more

What Men Need to Know About ED Drugs and Anesthesia

Posted 26 Jun 2017 by Drugs.com

MONDAY, June 26, 2017 – Men who take erectile dysfunction drugs need to alert the anesthetist before having surgery or other medical procedures, hospital experts say. Erectile dysfunction drugs such as Viagra and Cialis contain nitric oxide, which opens blood vessels and relaxes muscles. If they are combined with anesthesia and other medication used during surgery, a patient's blood pressure may become dangerously low, the American Association of Nurse Anesthetists said. The association said men must be forthright about their use of erectile dysfunction drugs and any other medications, including over-the-counter and herbal remedies. Men should stop taking erectile dysfunction drugs a few days before surgery, because they take at least 24 hours to clear the body, the group said. The association recommends that you make sure your spouse, a family member or friend knows you use an ... Read more

A Movie Instead of Anesthesia for Kids' Radiation Therapy

Posted 9 May 2017 by Drugs.com

TUESDAY, May 9, 2017 – For children with cancer, watching movies during radiation therapy might eliminate their need for general anesthesia, a new study suggests. Kid-friendly movies such as "SpongeBob SquarePants" and "Cars" helped reduce the risks, trauma and costs of treatment for kids evaluated in the small European study. Cancer is rare in children, but those who develop tumors in their brain, bone and other soft tissues may require radiation therapy. "Being treated with radiotherapy means coming in for a treatment every weekday for four to six weeks. The children need to remain motionless during treatment and, on the whole, that means a general anesthesia. That, in turn, means they have to keep their stomach empty for six hours before the treatment," said study author and radiation therapist Catia Aguas. "We wanted to see if installing a projector and letting children watch a ... Read more

Preparing for Anesthesia: 5 Tips You Should Know

Posted 7 Apr 2017 by Drugs.com

FRIDAY, April 7, 2017 – If you have surgery on your calendar, don't wait until the last minute to start preparing, especially if you're going to need anesthesia. The American Association of Nurse Anesthetists says you're more likely to avoid complications if you follow these five tips: Stop taking unnecessary medications. Only use necessary, approved prescriptions ahead of time. If you have had or currently have a problem with alcohol or drug abuse, tell the anesthesiologist. He or she will need to consider possible drug interactions that could affect your safety during and after surgery. Halt herbal supplements. Discontinue using alternative medicines at least two weeks prior to surgery. Some herbal products can cause complications during and after surgery, such as dangerously high or low blood pressure. Disclose your family medical history. Tell your anesthesiologist about any ... Read more

Steep Bills Surprise Patients Who Go 'Out-of-Network'

Posted 17 Jan 2017 by Drugs.com

TUESDAY, Jan. 17, 2017 – Patients using specialists outside their health-plan network often receive surprise bills for services that cost far more than what Medicare considers a fair rate, a new study suggests. Most insurers use rates set by Medicare – the publicly funded insurance program for the elderly – as the benchmark for what they'll pay health care providers. But a look at 400,000 U.S. physicians' charges found many doctors bill their private-paying patients two, three, even six times more than what Medicare pays for the same services, the study revealed. The highest markups – four or more times greater than the Medicare rate – were for certain specialty services, including anesthesiology, interventional radiology, emergency medicine and pathology. Anesthesiologists had the highest markup, charging six times what Medicare considers a reasonable amount, the researchers ... Read more

'Don't Cut Yet, Doc, I Can Hear You'

Posted 20 Dec 2016 by Drugs.com

MONDAY, Dec. 19, 2016 – Far fewer surgical patients become conscious while under general anesthesia than previously believed, researchers report. Of 260 patients examined on the operating table, less than 5 percent showed consciousness in response to stimuli, an international team of researchers found. The patients were tested before the start of surgery. None of them remembered being awake afterward. That rate is much lower than the 37 percent found in earlier studies, the researchers said. "Although we view such consciousness during surgery as an important issue, we urge caution in the interpretation of these results," said study leader Dr. Robert Sanders, from the University of Wisconsin School of Medicine and Public Health. "We looked at a very brief 'snapshot' of the time patients spend under anesthesia. In addition, these patients likely had very different experiences from those ... Read more

FDA Issues Anesthesia Warning for Pregnant Women, Kids Under 3

Posted 14 Dec 2016 by Drugs.com

WEDNESDAY, Dec. 14, 2016 – Repeated or lengthy use – longer than three hours – of general anesthetic and sedation drugs may harm the developing brains of fetuses and children younger than 3 years old, the U.S. Food and Drug Administration warned Wednesday. After reviewing the latest published studies, the agency announced that these warnings need to be added to the labels of these drugs. The agency also issued a Drug Safety Communication to inform health care providers, parents and caregivers of the potential danger. "We recognize that in many cases these exposures may be medically necessary, and these new data regarding the potential harms must be carefully weighed against the risk of not performing a specific medical procedure," Dr. Janet Woodcock said in an agency news release. She is director of the FDA's Center for Drug Evaluation and Research. "Parents and caregivers are often ... Read more

Anesthesia Safe for Kids, Doctors' Group Says

Posted 16 Jul 2016 by Drugs.com

FRIDAY, July 15, 2016 – Anesthesia eases the pain of millions of children who must have surgery every year, but parents who are worried about the safety of these medications should talk to their anesthesiologist about their fears, experts advise. "Particularly in infants and toddlers, surgery is only recommended when necessary for the child's health, so parents should not avoid an important procedure out of fear," said Dr. Randall Flick. He is chair of the Committee on Pediatric Anesthesia at the American Society of Anesthesiologists (ASA). "Physician anesthesiologists have completed years of special training to ensure safe, high-quality care, which should set parents' minds at ease," said Flick, who is also associate professor of pediatrics and anesthesiology at the Mayo Clinic in Rochester, Minn. There are many important details about children's health that anesthesiologists should ... Read more

Anesthesia Safe for Infants, Toddlers, Study Says

Posted 7 Jun 2016 by Drugs.com

TUESDAY, June 7, 2016 – General anesthesia doesn't seem to harm young children's mental development, new research concludes. "A number of animal studies have suggested that exposure to commonly used anesthetic agents in early development could lead to deficits in learning, memory, attention and other cognitive functions," said study author Dr. Lena Sun. She is a professor of pediatric anesthesiology and pediatrics at Columbia University Medical Center in New York City. "However, few clinical studies have adequately addressed whether this is also true in humans," Sun said in a Columbia news release. The new study findings are "good news for parents whose children need anesthesia for elective surgery or a diagnostic procedure," she added. Still, the study leaves some important questions unanswered, Sun said. "We need to take a closer look at the effect of anesthesia on cognitive function ... Read more

'Preemie' Babies May Face Long-Term Anesthesia Risks

Posted 25 Feb 2016 by Drugs.com

THURSDAY, Feb. 25, 2016 – Children born prematurely may be at risk for complications from anesthesia and sedation at least into young adulthood, a new study suggests. "Perhaps we should look at these children differently and provide different care to them," said study lead author Dr. Jeana Havidich, a pediatric anesthesiologist at Dartmouth-Hitchcock Medical Center in Lebanon, N.H. Premature babies often face medical issues that require diagnostic tests and procedures, even as they grow older, the study noted. And physicians know prematurity puts these people at higher risk when they need to be sedated, Havidich said. "We have a sense of heightened awareness, a gut feeling that these children are more challenging to manage," she added. But it's not clear, she said, at what point that risk goes away. The new study attempted to answer that question. The researchers examined the medical ... Read more

Minds of Older Women Fuzzier After General Anesthesia Than Men's

Posted 21 Jul 2015 by Drugs.com

TUESDAY, July 21, 2015 – Older women are much more likely than men to suffer brain dysfunction after surgery with general anesthesia, a new study finds. Researchers who analyzed data from hundreds of older adults in the United States found faster declines in mental function and brain volume for both women and men who had surgery with general anesthesia compared to those who had no surgery. But the long-term decline was much greater in women than in men. The mental fall-off was especially severe among women who had multiple surgeries with general anesthesia, the researchers said. "This is one of the first studies to suggest that among older adults, women are at a higher risk for postoperative brain dysfunction than men," study author Dr. Katie Schenning of Oregon Health & Science University, said in an association news release. "Our research clearly shows an association between surgery, ... Read more
