Dental Needle Could be Replaced

I find this study to be quite interesting as I have had anesthesia delivered directly in my nose before in an attempt to prevent my constant 24/7 headache. New evidence has emerged that a common local anesthetic, when administered to the nose as nose drops or a nasal spray, travels through the main nerve in the face and collects in high concentrations in the jaw, teeth, and structures of the mouth. William H. Frey II and colleagues found that drugs administered to the nose travel along nerves and go directly to the brain, although I really don’t think this finding is novel. One of those nerves is the trigeminal nerve, which brings feelings to the face, nose and mouth. Until now scientists never paid much attention to intranasal drugs passing the nerve in the nose and how it might reach the teeth, gums and other areas of the face and mouth to reduce pain sensations in the face and mouth. Researchers in this study found that lidocaine or Xylocaine, sprayed into the noses of laboratory rats, quickly traveled down the trigeminal nerve and collected in their teeth, jaws, and mouths at levels 20 times higher than in the blood or […]

Six Year Old Dies After Dentist Visit

A six year old boy has died during a recent visit to the dentist.  This said story has been reported by several news sources such as MSNBC. An autopsy is currently being conducted to determine the specific cause of death. However, the boy was given anesthesia  during the dental procedure and died after the breathing tube was removed. This tragic story has occurred in Virginia. Sedation certainly caries risks when at the dentist and I have previously reported on this blog of a case where someone has died after undergoing anesthesia while having their wisdom teeth removed. If you are considering having anesthesia while visiting the dentist or oral surgeon you should be aware of the risks and potential harmful complications that can occur.

Childhood Exposure to Anesthesia linked to Learning Disabilities

Mayo Clinic researchers have found that children undergo multiple surgeries with anesthesia during their first three years of life are at higher risk of developing learning disabilities. Using data from the Rochester Epidemiology Project, researchers studied the medical records of over 5,000 children fromwho were born between 1976 and 1982. The research team, led by Robert Wilder, M.D., Ph.D., a Mayo Clinic anesthesiologist, found that although one exposure to anesthesia was not harmful, more than one almost doubled the risk that a child would be identified as having a learning disability before age 19. The risk also increased with longer durations of anesthesia. Even so it is unclear whether the anesthetic, the physiological stress of surgery, or the medical problems that required surgery necessary are responsible for the increased risk of learning disabilities. The general anesthesia chemicals in use during the study period were primarily halothane and nitrous oxide (known commonly as laughing gas). Halothane is no longer used in the U.S. but has been replaced by similar agents. Nitrous oxide is widely used throughout the world and commonly in the dental setting. Other studies have linked anesthesia exposure in young children to behavioral problems. The research team would like […]
