PRETREATMENT: - Decrease S/E's of intubation PARALYSIS WITH INDUCTION: - Pt has LOC, then administer neuromuscular blocking agent PROTECTION AND POSITIONING: - Apply pressure over cricoid cartilage (minimizes likelihood of vomiting and aspiration PLACEMENT WITH PROOF - Each attempt NOT to exceed 30 seconds, max of 3 attempts. Ventilate pt 30-60 seconds between attempts. - After intubation, inflate the cuff - Confirm tube placement w/exhaled CO2 detector. POSTINTUBATION MANAGEMENT: - Secure ET tube - Set ventilator settings - Obtain Chest x-ray - Continue to medicate - Recheck VS and pulse oxtimetry What is a Combitube? - correct answer A dual-lumen, dual-cuff airway that can be placed blindly into the esophagus to establish an airway. If inadvertently placed into trachea, it can be used as a temporary ET tube. There are only two sizes: small adult and larger adult. Some causes: - Cardiac tamponade (may compress the heart during diastole to such and extent that atria cannot adequately fill, leading to decreased stroke volume). - Tension pneumothorax may lead to inadequate stroke volume by displacing inferior vena cava and obstructing venous return to right atrium. - Air embolus may lead to obstruction of pulmonary artery and subsequent obstruction to right ventricular outflow during systole, with resulting obstructive shock Explain Distributive Shock. - correct answer Results from disruption in SNS control of the tone of blood vessels, which leads to vasodilation and maldistribution of blood volume and flow. (Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? - correct answer As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? - correct answer Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. - correct answer When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. - correct answer Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose. In a compensatory response to shock, hepatic vessels constrict to redirect blood flow to other vital areas. Explain Pulmonary Response. - correct answer Tachypnea happens for 2 reasons: 1. Maintain acid-base balance 2. Maintain increased supply of oxygen * Metabolic acidosis from anaerobic metabolism will be a stimulus for the lungs to increase rate of ventilation. Increased RR is an attempt to correct acidosis + augments oxygen supply to maximize oxygen delivery to alveoli. Explain Irreversible Shock. - correct answer Shock uncompensated or irreversible stages will cause compromises to most body systems. - Inadequate venous return - inadequate cardiac filling - decreased coronary artery perfusion - Membranes of lysosomes breakdown within cells and release digestive enzymes that cause intracellular damage. How would you assess a pt in hypovolemic shock? - correct answer (Use Initial Assessment) and then: Inspect: - LOC - Rate and quality of respirations - External bleeding? - Skin color and moisture - Assess jugular veins and peripheral veins Auscultate: - BP - Pulse pressure - Breath sounds - Heart sounds - Bowel sounds Percuss: - Chest and abdomen Palpate: - Central pulse (carotid or femoral) - Positive inotropic effect (force of contraction) may be evidence by a bounding central pulse - Palpate peripheral pulses - Palpate skin temp and moisture Diagnostic Procedures: - Xrays and other studies - Labs Planning and Implementation - Oxygen - IV's with warmed replacement fluids - Control external bleeding with direct pressure - Elevate LE's - NGT - Foley - Monitor and pulse oximeter - Monitor for development of coagulopathies - Surgery? ICP is a reflection of what three volumes? What happens when one increases? - correct answer 1. Brain 2. CSF 3. Blood within the nonexpansible cranial vault As volume of one increases, the volume of another decreases to maintain ICP within normal range. As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia and lethal secondary insult. Hypotensive pt w/marginally elevated ICP can be harmful. Slightly elevated BP could protect against brain ischemia in a pt with high ICP. Cerebral ischemia can lead to increased concentration of CO2 and decreased concentration of O2 in cerebral vessels. CO2 dilates cerebral blood vessels = increase blood volume and ICP. What are the early signs and symptoms of increased ICP? - correct answer - Headache - Mild to severe memory impairment, cognitive, behavioral, and intellectual deficits What is a cerebral contusion and its S/S? - correct answer A common focal brain injury in which brain tissue is bruised and damaged in a local area. Mainly located in frontal and temporal lobes. May cause hemorrhage, infarction, necrosis and edema. Max effects of bleeding & edema peak 18-36 post injury. S/S: - Alteration in LOC - Behavior, motor or speech deficits - Abnormal motor posturing - Signs of increased ICP What is an epidural hematoma and its S/S? - correct answer Results when a collection of blood forms between the skull and the dura mater.

Usually venous, and not necessarily from a fx. Formation may be acute or chronic. Acute pt's hematoma manifest 48 hrs post injury S/S: - Altered LOC or steady decline in LOC - S/S of increased ICP - Hemiparesis or hemiplegia on opposite side of hematoma - Unilateral fixed and dilated pupil on same side of hematoma Chronic pt's " " up to 2 wks post injury - H/A - Progressive decrease in LOC - Ataxia - Incontinence - Sz's What are intracerebral hematoma's and its S/S? - correct answer Occur deep within brain tissue, may be single or multiple and commonly associated with contusions (frontal & temporal lobes).

Larger pneumo who are unstable or likely to deteriorate a chest tube is placed. - correct answer Simple pneumo interventions: Pt is at hospital in the right amount of time, right care, right trauma facility, right resources - correct answer Safe Care: What is vascular response? - correct answer As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. Uncontrolled Hemorrhage - correct answer Major cause of preventable death: What is renal response? - correct answer Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. reorganize care to C-ABC - correct answer If uncontrolled hemorrhage ..

A Alert. If the pt is alert he or she will be able to maintain his or her airway once it is clear. 2. V responds to verbal stimuli responds to pain. If the patient needs verbal stimulation to respond, an airway adjunct may be needed to keep the tongue from obstructing the airway. 3. P responds to pain. If the pt. responds only to pain, he or she may not be able to maintain his or her airway adjunct may need to be placed while further assessment is made to determine the need for intubation. 4. U Unresponsive. If the pt. is unresponsive, announce it loudly to the team and direct someone to chk in the pt is pulseless while assessing if the cause of the problem is the airway. - correct answer Airway and AVPU: What is a Laryngeal Mask Airway? - correct answer Looks like an ET tube but is equipped with an inflatable, elliptical, silicone rubber collar at the distal end. It is designed to cover the supraglottic area. ILMA, does not require laryngoscopy and visualization of the chords. ask pt to pen his or her mouth - correct answer While assessing airway the patient is alert and responds to verbal stimuli you should.. A 14 gauge needle that is inserted into the 2nd intercostal space in the midclavicular line on the affected side over the top of the rib to avoid neuromuscular bundle that runs under the rib. Prepare for chest tube placement. - correct answer Tension pneumo intervention jaw thrust maneuver to open airway and assess for obstruction. If pt has a suspected csi, the jaw thrust procedure should be done by two providers. One provider can maintain c-spine and the other can perform the jaw thrust maneuver. - correct answer While assessing airway pt is unable to open mouth, responds only to pain, or is unresponsive you should.. Explain adrenal gland response. - correct answer When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. 1.
