Spinal anesthesia, on the other hand, involves the injection of local anesthetics directly into the cerebrospinal fluid, resulting in rapid and profound anesthesia of the lower body. Nerve blocks entail the precise deposition of anesthetic agents near peripheral nerves, offering targeted pain relief for specific regions of the body [3-5].

The proficiency and knowledge of Resident Anesthetists in Himachal Pradesh regarding these regional anesthesia techniques are of paramount importance. The effective utilization of these techniques demands a deep understanding of anatomy, pharmacology and clinical applications. Moreover, staying abreast of the latest advancements in the field is essential to provide patients with the best possible care.

This study embarks on a journey to explore the realm of regional anesthesia among Resident Anesthetists in Himachal Pradesh. The primary aim is to assess their levels of awareness and knowledge regarding epidurals, spinals and nerve blocks and their applications. By doing so, we seek to gain insights into the readiness of these anesthesia professionals to harness the potential of regional anesthesia techniques to improve patient care.
