However, before giving the medicine, anesthesiologist carefully examines the condition of the pregnant woman to whom anesthesia is to be given. Epidural anesthesia during labor and normal delivery does not cause unconsciousness; thus, patients do not lose their psychological alertness (Halpern and Douglas 2008). Dissertation Part According to (Orebaugh 2011), epidural anesthesia is commonly administered by injecting the medicine in the lumbar region of the back, specifically in the epidural region.

In year 1799 anesthetic properties of Nitric Oxide were discovered by Humphery Davy (1778-1829) he advised that the by using nitric oxide, pain and shock of the surgical procedure can be negated. Third person who continue with Morton and Wells philosophy was Charles T. Jackson. The Fourth man who contributed to anesthetics was Thomas Mortan (Blatner, 2009). In the year 1848 James Simpson used chloroform in obstetric surgery, he

(Stremler, Halpern, Weston, Yee & Hodnett, 2009, p. 391). (De Sevo, M. & Semeraro, 2010, p. 11) the implications being that the overmedicalization of the labor and delivery process has been well intrenchend in nursing culture and may influence increased rather than decreased medical intervention use for women, even when they would not necessarily have needed it. The challenge to nursing is then to begin to support a reduction

Cardiac Stress Response: The Use of Anesthetic Technique to Promote Positive Outcome; Analyzing the Pros and Cons of Technique Cardiac surgery by nature elicits a powerful stress response resulting from activation of stress hormones including epinephrine, norpinephine and cortisol hormones among others. Surgical trauma and blood loss may contribute to this stress response. Some surgeons have suggested that cardio pulmonary bypass surgery in and of itself activates an inflammatory response that

elective or emergency childbirth, a choice between general and local anesthesia is often called for. Cognizing the surroundings helps the birthing process. Therefore, a local anesthetic administered via an intrathecal spinal injection or through a catheter in the epidural space will prove an advantage. Ratcliffe and Evans at John Radcliffe Hospital in Oxford, England attempted tested this advantage on more than 90 elective Cesarean parturients. (Ratcliffe & Evans, 1993)

For example, in these procedures it is often difficult to open the patient's mouth wide enough for laryngoscopy and intubation, thus creating the possibility that cardiopulmonary changes may be present and the "probability o lesions in oesophagus, bowel, kindneys, skin and joints." This information would not be known if not for this study and its reported findings. The study's conclusion is that the use of thoracic epidural anesthesia to sevoflurane
