Analgesia is a pain-free condition, whereas anesthesia is a state attained when there’s a loss of touch, pain, and temperature, sensations with or without loss of awareness. Anesthesia is associated with some grade of analgesia but not vice versa.


Mechanism of Action of Analgesics and Anesthetics

The most widely used class of analgesics namely, NSAIDs, Opioids etc. which helpsto reduce the stimulation of free nerve endings and blocks the transmission of pain signals.On the other hand, it’s act on both the peripheral nerves and the brain and alters pain perception [1].

When local anesthetics are injected around a nerve, they block the sodium channels present on the nerve. This blocking effect is voltagedependent, which means that thin nerve fibers that conduct signals faster, such as the pain fibers, are blocked significantly more effectively than larger nerves [1]. General anesthetics can be administered as a gas or intravenously. They produce a loss of pain, touch, temperature, and reflexes accompanied by loss of memory and consciousness.General anesthetics depress the central nervous system mainly through their effects on the inhibitory neurotransmitter GABA [1].

Combining Analgesia and Anesthesia

General anesthetics area unit seldom administered as sole agents for advanced operative procedures. A mix of adjuvants, like analgesics and/or muscles relaxants, area unit coadministered to realize the specified state of surgical anesthesia. Local and regional anesthesia may be used as another or additionally to standard pain management throughout and when surgery and also the immediate amount when birth. Analgesic opioids given as regional physiological condition and blood vessel patient-controlled physiological condition (PCA) have incontestible effective management of surgical pain [2,3]. Epidural physiological condition also can be used because the sole drug for surgeries and may be used because the primary anesthetic for surgeries from the chest to the lower extremities. This methodology of mixing opioid/non-opioid analgesics with anesthesia helps to reduce the pain with the dose and side effects of opioid analgesics, like nausea, vomiting, retardation of bowel movements resulting in constipation, and sedation [4,5].
