  103. Hypoglycemiamay-
    develop during anesthesia or postoperatively from in-adequate carbohydrates or excessive administration of in-sulin. Hyperglycemia, which can increase the risk for surgi-cal wound infection, may result from the stress of surgery,which can trigger increased levels of catecholamine.
  104. Corticosteroids-
    Prednisone (Deltasone) Cardiovascular collapse can occur if discontinued suddenly. Therefore, a bolus of corticosteroid may be administered intravenously immediately before and after surgery.

  109. Antibiotics-
    Erythromycin (Ery-Tab) When combined with a curariform muscle relaxant, nerve transmission is interrupted and apneafrom respiratory paralysis may result.
  110. Anticoagulants-
    Warfarin (Coumadin) Can increase the risk of bleeding during the intraoperative and postoperative periods; should bediscontinued in anticipation of elective surgery. The surgeon will determine how long before theelective surgery the patient should stop taking an anticoagulant, depending on the type ofplanned procedure and the medical condition of the patient.
  111. Antiseizure Medications-
    Intravenous administration of medication may be needed to keep the patient seizure-free in theintraoperative and postoperative periods.
  112. Thyroid Hormone-
    Levothyroxine sodium (Levothroid) Intravenous administration may be needed during the postoperative period to maintain thyroid levels.
  113. Opioids-
    Long-term use of opioids for chronic pain (6 mo or greater) in the preoperative period may alter the patient’s response to analgesic agents.
  114. The patient is transferred to the holding area about ___minutes
    The patient is transferred to the holding area or presurgical suite in a bed or on a stretcher about 30 to 60 minutes be-fore the anesthetic is to be given.
  115. malignant hyperthermia:
    a rare life-threatening conditiontriggered by exposure to most anesthetic agents induc-ing a drastic and uncontrolled increase in skeletal muscle oxidative metabolism that can overwhelm the body’scapacity to supply oxygen, remove carbon dioxide, andregulate body temperature, eventually leading to circula-tory collapse and death if untreated. Malignanthyperthermia is often inherited as an autosomaldominant disorder
  116. moderate sedation:
    previously referred to as conscioussedation, involves use of sedation to depress the levelof consciousness without altering the patient’s ability tomaintain a patent airway and to respond to physicalstimuli and verbal commands
  117. monitored anesthesia care-
    • moderate sedation adminis-tered by an anesthesiologist or
    • anesthetist

    the substance, such as a chemical orgas, used to induce anesthesia
  128. anesthetist-
    health care professional, such as a nurseanesthetist, who is trained to deliver anesthesia and tomonitor the patient’s condition during surgery
  129. circulating nurse (or circulator)-
    • registered nurse who co-ordinates and documents patient
    • care in the operatingroom
  130. epidural anesthesia:-
    • state of narcosis, analgesia, relaxation,and loss of reflexes
    • achieved by injecting an anestheticagent into the epidural space of the spinal cord
  131. general anesthesia-
    • state of narcosis, analgesia,relaxation, and loss of reflexes
    • produced by pharmaco-logic agents
  132. local anesthesia-
    • injection of a solution containing theanesthetic agent into the
    • tissues at the planned incisionsite
  133. Airborne bacteria are a concern. To decrease the amount of bacteria in the air,
    • standard OR ventilation pro-vides 15 air exchanges per hour, at least three of which are fresh air (Phillips, 2007). A room temperature of 20C to24C (68F to 73F),
    • humidity between 30% and 60%, and positive pressure relative to adjacent areas are maintained. Staff members shed skin scales, resulting in about 1000bacteria-carrying particles (or colony-forming units[CFUs]) per cubic foot
    • per minute. With the standard air exchanges, air counts of bacteria are reduced to 50 to 150CFUs per cubic foot per minute. Systems with high-efficiency particulate air (HEPA) filters are needed to remove particles larger than 0.3 µm
  134. Stage I: beginning anesthesia-
    As the patient breathes in the anesthetic mixture, warmth, dizziness, and a feeling of detachment may be experienced. The patient may have a ringing, roaring, or buzzing in the ears and, although still conscious, may sense an inability to move the extremities easily. During this stage, noises are exaggerated; even low voices or minor sounds seem loud and unreal. For this reason, unnecessary noises and motions are avoided when anesthesia begins.
  135. Stage II: excitement. The excitement stage-
    • characterized variously by struggling, shouting, talking, singing, laughing, or crying, is often avoided if the anesthetic agent is administered smoothly and quickly. The pupils dilate, but they contract if exposed to light; the pulse rate is rapid, and respirations may be irregular. Because of the possibility of uncontrolled movements of the patient during this stage, the anesthesiologist or anesthetist must always be
    • assisted by someone ready to help restrain the patient. Manipulation increases circulation to the operative site and thereby increases the potential for bleeding
  136. Stage III: surgical anesthesia-
    • reached by continued administration of the anesthetic vapor or gas. The patient is unconscious and lies quietly on the table. The pupils are small but contract when exposed to
    • light. Respirations are regular, the pulse rate and volume are normal, and the skin is pink or slightly flushed. With proper administration of the anesthetic agent, this stage may be aintained for hours in one of several planes, ranging from light (1) to deep (4), de-pending on the depth of anesthesia needed.
  137. Stage IV: medullary depression-
    • This stage is reached if too much anesthesia has been
    • administered. Respirations become shallow, the pulse is weak and thready, and the pupils become widely dilated and no longer contract when exposed to light. Cyanosis develops and, without prompt intervention, death rapidly follows. If
    • this stage develops, the anesthetic agent is discontinued mmediately and respiratory and circulatory sup-port is nitiated to prevent death. Stimulants, although rarely used, may be administered; narcotic antagonists can be used if the over dosage is due to opioids.
  138. During anesthesia, the patient’s temperature may fall.
    Glu-cose metabolism is reduced, and, as a result, metabolic aci-dosis may develop. This condition is called hypothermiaand is indicated by a core body temperature that is lower than normal
  139. Malignant hyperthermia-
    • is a rare inherited muscle dis-order that is chemically induced by anesthetic agents(Rothrock, 2007). MH can be triggered by myopathies, emo-tional stress, heatstroke, neuroleptic malignant syndrome,strenuous exercise exertion, and
    • trauma. Susceptible people include those with strongand bulky muscles, a history of muscle cramps or muscle weak-ness and unexplained temperature elevation, and an unex-plained death of a family member during surgery that was ac-companied by a febrile response
  140. This disruption ofcalcium causes clinical symptoms of
    hypermetabolism,which in turn increases muscle contraction (rigidity) andcauses hyperthermia and subsequent damage to the centralnervous system.
  141. nursing diagnosesmay include the following:
    Anxiety related to surgical or environmental concerns•Risk of latex allergy response due to possible exposureto latex in OR environment
  142. dehiscence-
    partial or complete separation of wound edges
  143. evisceration-
    protrusion of organs through the surgical incision
  144. first-intention healing-
    method of healing in which woundedges are surgically approximated and integumentarycontinuity is restored without granulation
  145. Phase I PACU-
    area designated for care of surgical patientsimmediately after surgery and for patients whose condi-tion warrants close monitoring
  146. Phase II PACU-
    area designated for care of surgicalpatients who have been transferred from a phase IPACU because their condition no longer requires theclose monitoring provided in a phase I PACU
  147. Phase III PACU-
    • setting in which the patient is cared for inthe immediate
    • postoperative period and then preparedfor discharge from the facility
  148. postanesthesia care unit (PACU)-
    • area where postopera-tive patients are monitored as they
    • recover from anes-thesia; formerly referred to as the recovery room orpostanesthesia recovery room
  149. second-intention healing-
    method of healing in whichwound edges are not surgically approximated andintegumentary continuity is restored by the processknown as granulation
  150. third-intention healing-
    method of healing in which surgi-cal approximation of wound edges is delayed andintegumentary continuity is restored by apposing areasof granulation

    • phase I PACU,used during the immediaterecovery phase, intensive nursing care is provided.
    • In thephase II PACU,the patient is prepared for self-care orcare in the hospital or an extended care setting.
    • In phaseIII PACU,the patient is prepared for discharge.
  152. Nursing Diagnoses
    • Based on the assessment data, major nursing diagnoses mayinclude the following:
    • •Risk for ineffective airway clearance related to de-pressed
    • respiratory function, pain, and bed rest
    • •Acute pain related to surgical incision
    • •Decreased cardiac output related to shock or hemorrhage •Risk for activity intolerance related to generalizedweakness secondary to surgery
    • •Impaired skin integrity related to surgical incision
    • and drains
    • •Ineffective thermoregulation related to surgical envi-ronment and anesthetic agents
    • •Risk for imbalanced nutrition, less than body require-ments related to decreased intake and increased needfor nutrients secondary to surgery
    • •Risk for constipation related to effects of medications,surgery, dietary change, and immobility
    • •Risk for urinary retention related to anesthetic agents
    • •Risk for injury related to surgical procedure/positioningor anesthetic agents
    • •Anxiety related to surgical procedure•Risk for ineffective management of therapeutic regi-men related to wound care, dietary restrictions, activ-ity recommendations, medications, follow-up care, orsigns and symptoms of complications
    • Collaborative Problems or Potential Complications Based
    • on the assessment data, potential complications mayinclude the following:
    • •Pulmonary infection/hypoxia
    • •Deep vein thrombosis (DVT)
    • •Hematoma or hemorrhage
    • •Infection
    • •Pulmonary embolism
    • •Wound dehiscence or evisceration
  153. anaphylactic shock-
    circulatory shock state resulting froma severe allergic reaction producing an overwhelmingsystemic vasodilation and relative hypovolemia
  154. biochemical mediators-
    messenger substances that maybe released by a cell to create an action at that site orbe carried by the bloodstream to a distant site beforebeing activated; also called cytokines
  155. cardiogenic shock:
    shock state resulting from impairmentor failure of the myocardium
  156. circulatory shock-
    shock state resulting fromdisplacement of blood volume creating a relative hypov-olemia and inadequate delivery of oxygen to the cells;also called distributive shock
  157. colloids-
    intravenous solutions that contain molecules thatare too large to pass through capillary membranes
  158. crystalloids-
    intravenous electrolyte solutions that movefreely between the intravascular compartment and interstitial spaces
  159. hypovolemic shock-
    shock state resulting from decreasedintravascular volume due to fluid loss
  160. multiple organ dysfunction syndrome-
    presence ofaltered function of two or more organs in an acutely illpatient such that interventions are necessary to supportcontinued organ function
  161. neurogenic shock-
    shock state resulting from loss of sym-pathetic tone causing relative hypovolemia
  162. septic shock-
    circulatory shock state resulting fromoverwhelming infection causing relative hypovolemia
  163. shock-
    physiologic state in which there is inadequate blood flow to tissues and cells of the body
  164. systemic inflammatory response syndrome-
    overwhelming inflammatory response in the absence of infectioncausing relative hypovolemia and decreased tissue perfusion
  165. management in all types and all phases ofshock includes the following-
    • •Support of the respiratory system with supplementaloxygen and/or mechanical ventilation to provide optimal oxygenation •Fluid replacement to restore intravascular volume •Vasoactive medications to restore vasomotor tone and improve cardiac function
    • •Nutritional support to address the metabolic requirements that are often dramatically increased in shock
  166. When vasoactive medications are administered-
    When vasoactive medications are administered, vitalsigns must be monitored frequently (at least every 15 minutes until stable, or more often if indicated). Vasoactive medications should be administered through a central venous line, because infiltration and extravasation of some asoactive medications can cause tissue necrosis and sloughing. An IV pump or controller should be used to ensure that the medications are delivered safely and accurately
  167. Hemodynamic Monitoring-
    • is initiated to assess the patient’sresponse to treatment. In many
    • institutions, this is per-formed in the intensive care unit (ICU), where an arterialline can be inserted.
  168. Medications commonly combined to treat cardiogenic shock include
    dobutamine, nitroglycerin, and dopamine.
  169. Dobutamine-
    produces in otropic effects by stimulating myocardial beta-receptors, increasing the strength of myocardial activity and improving cardiac out-put.
  170. Nitroglycerin.
    IV nitroglycerin in low doses acts as a venousvasodilator and therefore reduces preload. At higher doses,nitroglycerin causes arterial vasodilation and therefore re-duces afterload as well.
  171. Dopamine-
    is a sympathomimetic agent that hasvarying vasoactive effects depending on the dosage. It may be used with dobutamine and nitroglycerin to improve tissue perfusion.
  172. vasoactive agentsthat may be used in managing cardiogenic shock include-
    norepinephrine, epinephrine, milrinone, vasopressin, and phenylephrine.
  173. Drotrecogin alfa(Xigris) -
    Drotrecogin alfa-
    • Drotrecogin alfa(Xigris)- acts as an antithrombotic, anti-inflammatory, andprofibrinolytic agent.
    • Drotrecogin alfa- acts as an anti-inflammatory cytokine, it stimulates
    • fibrinolysis- restoring bal-ance in the coagulation–anticoagulation homeostatic processof the body’s inflammatory response to injury and infection.
    • Drotrecogin alfa- has provided a significant breakthroughin the successful pharmacologic treatment of patients with sepsis.
  174. It is important to elevate and maintain the head of the bed at least __ degrees to prevent neurogenic shock when a patient receives spinal or epidural anesthesia.
    It is important to elevate and maintain the head of the bed at least 30 degrees to prevent neurogenic shock when a patient receives spinal or epidural anesthesia.
  175. what are some inhalation anesthetic drugs?
    halothane, enflurane
