Anesthesia in Young Children is Not Linked to a Lower IQ

  • Having a child with health issues can be extremely stressful on parents and guardians, especially when the young child needs to undergo a serious procedure that requires anesthesia. While parents are often apprehensive about the effects anesthesia may have on their child in the future, a new study from the Mayo Clinic shows anesthesia in young children is not linked to a lower IQ. This topic is often researched, and the results from this particular study should be reassuring to parents with children in need of surgery. This particular study researched a group of 997 children born between 1994 and 2007, all from the same county. 380 of these children had been exposed to anesthesia once before the age of three, 206 children had been exposed to anesthesia two or more times, and 411 children had never been exposed to anesthesia in their lifetime. 42% of those studied had received anesthesia due to a surgery for medical conditions involving the ears, nose, and throat. The group was given brain function tests between age 8 and 12 and again between age 15 and 20. When the results from this study were assessed, there were no significant differences between the three groups in the areas of intelligence, memory, and other brain functions that were measured. Children exposed to anesthesia multiple times before the age of three did, however, have a slight decrease processing speed of the brain and in fine motor coordination. These children also had a greater likelihood of behavioral problems and learning difficulties.  This is evidence that anesthesia in young children is not linked to a lower IQ. “These secondary outcomes must be interpreted cautiously,” write the researchers, “but [they] suggest … that exposure to multiple procedures requiring general anesthesia is associated with a subtle, specific pattern of injury that may have consequences for subsequent learning and behavior.” This was an observational study, which means the results that showed lower scores in motor skills and brain processing, could be unrelated to the multiple exposures to anesthesia. Dr. David Warner, the study’s lead author and a pediatric anesthesiologist at the Mayo Clinic Children’s Center in Rochester doesn’t want this study’s findings to scare parents.  “The last thing I want to do is prevent any child who needs an operation from getting it because of this,” he said. “Overall, the results are pretty reassuring,” said Dr. David Warner,“There’s not much evidence that a single exposure is associated with any harmful outcome.” Of children that need surgery before the age of three, more than 80% of children only undergo that one procedure. While this topic is still being researched, this study should give parents some peace of mind wthat anesthesia in young children is not linked to a lower IQ. The results show that when the benefits of the surgery outweigh the risks of anesthesia, parents should be able to make the decision with less stress and worry.

  • Studies on anesthesia are continuously providing us with new information and a better understanding of the effects it may have on patients undergoing surgery. Many people are apprehensive before undergoing any procedure, but especially when it requires general anesthesia. Many studies have been conducted to answer the question can anesthesia cause memory problems? A new study shows that any cognitive changes in patients after anesthesia are very small and insignificant. The study analyzed a group of middle-aged men and women, with an average age of 54 years old. 312 who had had one or more procedures that require general anesthesia and 652 people who had never been under general anesthesia. None of the people studied had ever had neurological or heart surgery, because both can affect cognitive performance. At the start of the study, all participants had normal cognitive functioning. The results of the study showed that on average, the participants who had been under general anesthesia had small declines in immediate memory over a four year period. It also showed that people who were exposed to general anesthesia for longer periods of time, for longer surgeries, showed greater declines in executive functioning, which includes skills like planning and focusing. While small changes were seen, study author Dr. Kirk Hogan, a professor of anesthesiology at the University of Wisconsin-Madison School of Medicine and Public Health, said “the cognitive changes after surgery are small — most probably asymptomatic and beneath a person’s awareness,” Although this study did show some minor declines, researchers say the study results still cannot directly tie cognitive performance declines to anesthesia. Other conditions, the surgery itself, and other factors may affect these declines in the people involved in the study. This topic will continue to be studied, but this should give patients some peace of mind knowing that if there is some type of cognitive decline due to anesthesia, it is very insignificant and not noticeable to the average person.

  • In today’s modern world, the use of anesthesia during a medical procedure has become a necessity and is extremely common. The luxury of being “asleep” and feeling no pain during a surgery is something we can’t imagine living without this day in age. This was not always the case, and the first use of anesthesia took place in 1846 during a procedure to remove a tumor in a patient’s neck. At that time, the drug of choice was ether which did indeed knock the patient unconscious, but unfortunately was extremely dangerous. Today, there are many options anesthesiologists can use, however it is still not completely clear how the process of anesthesia works. A recent study has shown like humans, plants react to general anesthesia. Scientists and doctors are continuously researching the science of anesthesia and we are constantly finding out more about the process. One group of researchers formed a study that explored the effects of anesthesia on plants and concluded that plants react to general anesthesia. Scientists have known for some time that plants are affected by anesthesia, in fact, Claude Bernard discovered this over one hundred years ago. This new study explored this fact even further and had the goal of understanding the link between the plant and animal system in terms of anesthesia. One of the plants used in this study was Dionaea muscipula, also known as the venus flytrap. Researchers first observed the venus flytrap as it functions normally, where triggering hairs in the plants trap causes it to snap shut. After exposing the plant to diethyl ether gas, the plant is unresponsive to the trigger. After 15 minutes, it seems the plant recovers and then responds to a trigger. The team of scientists conducting this research, hope their results from this study will help unlock the mystery of how anesthesia works in humans. The team of researchers from Germany, Japan, the Czech Republic, and Italy published their study in Annals of Botany. This ongoing research is helpful to doctors and anesthesia providers, as well as to patients. The more information patients have on the process of anesthesia, the more they can be at ease when preparing for a procedure.
