Redheads Require More Anesthesia
By Kaye Nemec
It seems ridiculous to say out loud, but the fact of the matter is that studies have proven that redheads actually require more anesthesia than blondes, brunettes etc. In 2004 a study was published in Anesthesiology that found that up to 20% more anesthetic was needed to achieve the same result in redheads that had been achieved in the blondes and brunettes taking part in the study.
So how does this make any sense? Without getting all scientific (those details can be found here) the bottom line is that redheads have specific mutations on the MCR1 gene that not only increase expression of red pigment but may also be involved with the function of the central nervous system.
This study opened the door for scientists to learn more and more about anesthesia and how it affects different patients. Do you know people who swear Tylenol or Ibuprofen doesn’t do anything for them? How about people who swear they have to take more than the recommended dosage in order for the medicine to take effect? Perhaps there is some truth to their claims after all. This study is a breakthrough in what could be a detailed explanation of how different people are affected by different medications.
