Common Nerve Blocks in General Surgery
The last few years have seen a dramatic development in the field of anaesthesia, especially nerve blocks. With sound anatomical knowledge, specific nerves can be blocked to impart selective anaesthesia to the area of surgery. There has been a progress from blind localization of nerves based on anatomical landmarks to the use of peripheral nerve locators and now the use of ultrasound guidance. Ultrasound can identify individual nerves, their anatomic variants and can help us to give real time injections as well as document them. These developments have opened up new horizons allowing us to administer nerve blocks to even the most morbid and high-risk patients without disturbing the rest of the anatomy as well as physiology. This technique of “selective anaesthesia” has been our principle at Abhishek Day Care Institute.
