Transcript: Chemical Formula Objectives Anesthesia-medicines that can numb pain locally or cause unconsciousness and decrease pain over the entire body Austin Callahan Nathan Stratton General-used during medical and surgical procedures that would be too painful to endure while awake, (mask over nose and mouth) Local-given by injection to numb parts of the body during surgery and dental procedures, (needle). Can also be used to numb eye before certain examination. *Ointments, sprays, and lotions are also local anesthetics What is anesthesia What was used before anesthesia How anesthesia works The main types of anesthesia Most common anesthesia Chemical Formula of anesthesia Types of Anesthetics Desflurane Soporifics and Narcotics-marijuana, belladonna and jimsonweed Mesmerism or hypnosis Knock patient unconcious with physical strike Counterirritants such as stinging nettles Alcohol and opium (most common) *Unfortunately, the large doses of alcohol needed to produce stupefaction were likely to cause nausea, vomiting and death instead of sleep. Opium, while a strong analgesic, had significant side effects itself and was typically not powerful enough to completely blunt a surgical stimulus. Local Before anesthesia Nitrous oxide (N20) -Discovered towards the end of the 18th century and is still being used today -Colorless, odorless gas -Discovered by Joseph Priestley -Nicknamed laughing gas (Humphrey Davy realized it had psychological effects) -Used as a sale product in traveling medicine shows and carnivals (before use was found for medical purposes) diethyl ether Conclusion Anesthesia Chem Study Anesthesia How Anesthesia Works Most Common Anesthetic Anesthesia works by preventing sodium ions from going from one nerve cell to the next. An easy explanation would be that the anesthetic molecules bind to a nerve cell and block the openings through which the sodium ions are released. Anesthesia-pain killer for surgery Alcohol and opium (most common), among other options Types of Anesthesia: -General (nose and mouth mask, leads to unconciousness) -local (needles, creams, lotions, sprays, applied to specific area) Most common anesthesia-Nitrous oxide Chemical formula-varies, but sodium ions inhibit the nerve cells in all to prevent sensitivity to surgical procedure General

Epidural Anesthesia Presentation

Transcript: Epidural anesthesia decreases pulmonary function during labor. Lung function is decreased during the procedure due to the motor blockade. Women that have severe asthma or chronic pulmonary disease need to put this information into consideration. An epidural anesthesia is the best method of anesthesia for postoperative outcome and has the lowest chance of postoperative pulmonary complications (Groeben 290). The purpose of this analysis is to provide an overview for anesthesiologists, obstetrics professionals, and women considering an epidural anesthesia (Merrill 1). Anesthesia and analgesia are interchangeable terms, analgesia is just one general aspect of anesthesia. Works Cited Thesis Statement Epidural Anesthesia and Health Risks Neurological Deficits Following Epidural or Spinal Anesthesia (Halpern et al.) Effects of Epidural vs Paternal Opioid Analgesia on the Progression of Labor Epidural anesthesia provides numerous benefits for women in labor. It prevents both, the adverse biochemical changes and stress during labor. The procedure also prepares women for the possibility of forceps, cesarean section, or the delivery of a second twin without the need for general anesthesia. This method is also beneficial for women with pre-eclampsia; this method suppresses noradrenaline contractions, instead producing beneficial haemodynamic changes ( Reynolds 751). Epidural Analgesia in Obstetrics Paralysis can occur after an epidural anesthesia procedure. The paralysis occurs in three out of fifty thousand women that have an epidural anesthesia during labor. The paralysis has lasted from seventy two hours up to four months after the procedure (Kane 150).The paralysis could have been caused by being administered a toxic chemical or by a chemical contamination of the anesthesia (Kane 159). " Epidural anesthesia for women in labor may be beneficial at the time of labor, but it is not always beneficial for women in the long run" (Merrill 1). Epidural Anesthesia and Pulmonary Function Women that experience labor at night have to deal with the increased risk of an unintentional dural puncture in the lower back. The unintentional dural puncture is caused from the anesthesiologist being fatigued, motor skills not as sharp, and less focused. A dural puncture can occur at any time of day this causes backaches and headaches for an unspecified duration after the epidural anesthesia procedure (Aya 666). Increased Risk of Unintentional Dural Puncture in Night-time Obstetric Epidural Anesthesia Epidural Analgesia Compared With Combined Spinal-Epidural Analgesia During Labor in Nulliparous Women Epidural anesthesia prevents walking during labor, for the procedure causes a motor blockade. A combined spinal-epidural anesthesia injection is a one time injection that allows for movement. This procedure is a one time injection, unlike an epidural anesthesia which remains in during labor. Since this method does not cause a motor blockade their is no chance of paralysis (Nageotte et al.). Images found on google images
