Does brain surgery cause loss of movement in arms and legs?|மூளை அறுவை சிகிச்சையால் கை கால்கள் செயலிழக்க வாய்ப்புள்ளதா?| Dr.Roopesh Kumar #Neuromonitoring #ionm #DrRoopeshKumar The minute we say a surgery needs to be done, they ask, “does the surgery cause the limbs to become immobile? Does the surgery result in speech loss?” Here is the answer for such questions. We understood about FMRI. We also understood tractography. How do we use it inside the operation theatre? For example, an electrician will come to a house and they check if there is a power supply in a specific electrical point using a tester. They will check using the tester. “This electric point isn't working. There is no electricity supply. We will have to use a different power line” is what they would say. That is called a tester. Something similar can be used for the brain. Like I have mentioned before, the circuits in the brain are similar to electrical circuits and there is a switch for the legs and wire-like connections. How is it checked then? We insert two needles like electrodes in the leg. When it is stimulated in the brain, vibrations are felt in the leg. That is shown in the computer in the form of a graph. This is called 'motor evoked potentials'. Sensations are also similar to this. Such evoked potentials can be monitored on the computer inside the theater by inserting a needle continuously by a dedicated doctor, the physiologist. In the majority of the operation theaters they have become an important member. Not just the anesthetist, but the electrophysiologist is also present. So what is their role? When we suggest a surgery, the patients immediately ask, Will the surgery lead to paralysis of the limbs? Will the surgery lead to loss of speech? For such questions this is the answer. So when such a surgery is done, if we check the 'evoked potentials', “are the nerves affected when the surgery is done? how close or how far is the nerve to the location of surgery?” Can be understood. We call it ‘intraoperative neuro monitoring’ or IONM. In the recent 5 years, there has been great development and there are advancements made on a daily basis. So, using an instrument like this, we receive continuous live feedback. For us, the operating surgeons, they keep telling us, “all motors are functional and the machine readings are good and the sensory potentials are correct” which means that we can continue to remove the tumor safely. When we near the tracks or the wires they tell us, "sir in 2 to 3 millimeters you will be coming close to the nerves," then we become cautious. So we alert ourselves. So we stop at that stage itself. We will not remove the tumor after that point. So a small rim or if a small part of the tumor around the nerve is left as such, so that the nerves going to the hands and legs can be protected and the nerves connected to speech can be protected. All these are called, 'intraoperative neuro monitoring'.
