General anaesthesia is a state of controlled unconsciousness that is administered to a patient when undergoing some treatment, during which you feel nothing and have no memory of whatever happened during the process. Local anaesthesia on the other hand is administered directly to that small part of the body that needs to be treated. The patient is conscious and can respond to both verbal and physical instructions from the doctor and people around.


General anaesthesia is mostly used during major operations on the lungs, brain, heart, or abdomen. This helps in saving the patients from the terrifying experiences and pain during the process. Local anaesthesia is used on minor medical procedures such as tooth extraction or a root canal, and minor eye operations such as cataract removal among others.

General anaesthesia can only be administered by a specialist doctor who’s supported by a team of trained staff such as theatre nurses, operating department practitioner and recovery room staff who takes care of the patient until the end of the operation. Local anaesthesia can be administered by dentists, anaesthetists and other doctors and can be given in form of injections, creams sprays or ointments.

General anaesthesia will esquire a lot of preparations since it involves major treatment procedures which will also take a long time to complete. The medication may also take time to respond unlike in local anaesthesia where fewer preparations take place. The treatment under local anaesthesia takes less time too and the patient can leave the hospital immediately.

During treatment, the general anaesthesia administered patients will experience a significant blood loss as compared to those on local anaesthesia.

General anaesthesia has more risks than the local one. Older people are at a higher risk of heart attack, postoperative confusion, pneumonia and stroke, especially if the patient had pre-existing conditions such as diabetes, cardiac problems, high blood pressure, obesity or overweight, kidney or lung conditions, among others. On the other hand, local anaesthesia has temporary side effects like dizziness, blurred vision, headaches, drowsiness, weakness or pins and needles.
