Effectiveness of Different Types of Injected Anesthesia

I just want to comment that I have a genetic connective tissue disorder, Ehlers-Danlos Syndrome and it has been noted that Lidocaine does not work well on many of us with EDS. In myself, it takes much more to be effective, takes much longer to take effect and wears off much quicker than normal. EDS is not as rare as some doctors may think. Lately researchers are thinking that it may be as common as 1 in 500 people. Many people don't even know they are affected as it presents as various types (13 currently) and with varied presentation from mild to severe. Doctors are not usually taught to recognize it as it used to be thought of as 'too rare' to deserve much, if any, time in medical school.

The three most common types of EDS are Hypermobile (unusually flexible joints), Classical (soft very stretchy skin), or Vascular (prone to aortic dissections and people often don't live past 40). These identifiers I have listed in brackets are only one of the many characteristics of each type of EDS. There are many other characteristics and it often takes a geneticist to identify the Syndrome. Since it involves all the connective tissue, and the body is about 1/3 connective tissue, usually there are many systemic symptoms. Sometimes people who have been diagnosed with fibromyalgia actually have Hypermobile EDS, so it may be important to ask them if they also happen to be 'double jointed' either now or as children.

Anecdotally, Carbocaine is thought to work much better than Lidocaine. Also the nerves in EDS patients can sometimes not be in the expected locations. Just so you know.

I also have heard that redheads can have challenges with anesthesia as well...
