Document Summary
Objectives: describe the broad types of anesthesia (general, neuraxial and regional, understand the basic mechanism of action and complications associated with drugs during anesthesia. Types of anesthesia: general anesthesia (cid:862)drug-induced loss of consciousness during which patients are not arousable, even by pai(cid:374)ful sti(cid:373)ulatio(cid:374)(cid:863) american society of anesthesiologists, often used with drug-induced neuromuscular blockade, loss of respiration and protective airway reflexes, neuraxial anesthesia. Can be used as a sole anesthetic technique for surgery or to provide analgesia after surgery: subarachnoid: cerebrospinal fluid filled space around the spinal cord. These are termed spinal anesthetics and are often used for lower extremity surgery (e. g. joint replacements, caesarian sections: regional anesthesia. Injection of anesthetic medication in the area of surgery rather than around a specific nerve: this is often used for minor surgery (e. g. small mole removal) Anesthesia is defined as a lack of sensation. There are several goals that we consider when providing types of anesthesia.
