Nerves are very delicate and they can be quite easilydamaged during the surgeries. Things like scalpel cuts or contusions orinflammation of areas surrounding those nerves can bring a considerable harm tothem. But the source of nerve damage does not have to be strictly physical.Another thing that can provoke nerve damage is anesthesia, whether it isthrough its medication or the syringe which inserts it into the body. Theunfortunate thing is that nerve damage can often be irreparable.
Types of nerve damages
There are three kinds of nerve damages and they areneuropraxia, neurotmesis and axonotmesis. What happens in neuropraxia does notaffect the composition of the nerves. When the nerve obtains such an injurywhich leads to neuropraxia, it means that the conveyance of the nerve impulsehas been disrupted, causing problems with supplying the blood to the nerve inquestion, as well as nerve compression. Luckily, this kind of nerve damage canbe fixed. Neurotmesis is the most serious and the most intense kind of nervedamage. It is followed by stretching, bruising and tearing. However, it istreatable. Finally, axonotmesis causes disturbance in the function of theso-called axon, which is the connecting fiber of a nerve cell, but the core ofthe fiber stays well-protected. This type of nerve damage is extremelydangerous and leads to paralysis, and it affects sensory, motor and autonomicnerves.
Symptoms of nerve damage
Nerve damage is not noticeable during surgery, only afterdoes it become apparent. A very strong burning pain in the damaged area is verycharacteristic for nerve damage, but on the other hand, some may experiencenumbness and itching. Also, even though it is the most likely alternative, thesensations which signify the presence of nerve damage do not necessarily haveto manifest themselves in the exact areas which are affected. Finally, anothersymptom of nerve damage is inability to walk properly, and it is usuallymanifested through some kind of issue with the feet, like weakness, dragging orfoot drop, which is the dropping of the front of the foot due to muscle damage.The nerve damage which affects the legs in any way leads to a condition calledfemoral nerve dysfunction. Femoral nerve dysfunction most commonly happensduring surgeries in which the patient is required to remain in a position wherehe is on his back with bent legs. Damage to the femoral nerve means disruptionin the sensation of thighs and lower part of the legs.
