Anesthesia and Its Role in Clinical Sciences


Anesthesia or anaesthesia (from Greek "without sensation") is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes. It may include analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), or unconsciousness. A patient under the effects of anesthetic drugs is referred to as being anesthetized.

Anesthesia enables the painless performance of medical procedure that would otherwise cause severe or intolerable pain to an unanesthetized patient, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist:

  • General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation. A patient receiving general anesthesia can lose consciousness with either intravenous agents or inhalation agents.
  • Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness.
  • Regional and local anesthesia, which blocks transmission of nerve impulses from a specific part of the body. Depending on the situation, this may be used either on its own (in which case the patient remains conscious), or in combination with general anesthesia or sedation. Drugs can be targeted at peripheral nerves to anesthetize an isolated part of the body only, such as numbing a tooth for dental work or using a nerve block to inhibit sensation in an entire limb. Alternatively, epidural, spinal anesthesia, or a combined technique can be performed in the region of the central nervous system itself, suppressing all incoming sensation from nerves outside the area of the block.

In preparing for a medical procedure, the clinician chooses one or more drugs to achieve the types and degree of anesthesia characteristics appropriate for the type of procedure and the particular patient. The types of drugs used include General Anesthetics, Local Anesthetics, hypnotics, sedatives, neuromuscular-blocking drugs, narcotics, and analgesics.

Our esteemed journal PULACR is looking forward for the upcoming issue (Volume3: Issue 1) for the upcoming issue as all the authors are invited to submit their recent scientific work through manuscripts in the mode of Research/Case Reports/Case Studies/Reviews/Short Review/ Short Communications/Commentaries/Short Commentaries/Letters to Editor/ Image articles etc.,

Our Journal welcomes submissions of manuscripts on the topics covering Anesthesia ,Anesthetics, Local Anesthesia, Spinal Anesthesia, Critical Care, Perioperative medicine, Airway Management, etc., In the quality perspective, the journal is determined to maintain an exceptionally high standard in both facts and ethics. Accuracy and authenticity in the scientific reports of present journal are conserved above all nominal needs of the time.

A standard editorial manager system is utilized for manuscript submission, review, editorial processing and tracking which can be securely accessed by the authors, reviewers and editors for monitoring and tracking the article processing. Manuscripts can be uploaded online at Editorial Tracking System  or as email attachment to
