MARCH Which of the following mnemonics can help the nurse prioritize care for a trauma patient with massive uncontrolled hemorrhage? What is kinematics? A branch of mechanics (energy transfer) that refers to motion and does not consider the concepts of force and mass of the object or body. What is Newton's First Law? A body at rest will remain at rest. A body in motion will remain in motion until acted on by an outside force. What is the Law of Conservation of Energy? Energy can neither be created nor destroyed. It is only changed from one form to another. What is Newton's Second Law? Force equals mass multiplied by acceleration of deceleration. What is kinetic energy (KE)? KE equals 1/2 the mass (M) multiplied by the velocity squared. What is the Mnemonic for the Initial Assessment? - Symptoms that help to locate area of injury in brain What are the interventions for Disability? - If assessment indicates a decreased LOC, conduct further investigation during secondary focused assessments - If pt is not alert or verbal, continue to monitor for any compromise to ABC's - If pt demonstrates signs of herniation or neurologic deterioration, consider hyperventilation. What is assessed and intervened for Expose/Environmental Controls? - Remove clothing - Ensure appropriate decontamination if exposed to hazardous material - Keep pt warm - Keep clothing for evidence What is the first thing assessed under the Secondary Assessment? FULL SET VS / FOCUSED ADJUNCTS / FAMILY PRESENCE - ABCDE should be completed - Labs, X-rays, CT, Foley, - Family Presence What is the second thing assessed under the Secondary Assessment? GIVE COMFORT MEASURES - Talking to pt - Pharmacologic/Nonpharmacologic pain management - Observe for physical signs of pain What is assessed under the Mnemonic "H"? HISTORY / HEAD-TO-TOE ASSESSMENT - MIVT - M = Mechanism of injury - I = Injuries sustained - V = Vital Signs - T = Treatment - Pt generated information - PMH - Head-to-toe assessment What is assessed under the Mnemonic "I"? INSPECT POSTERIOR SURFACES - While maintaining C-spine, logroll pt with assistance to inspect back, flanks, buttocks and posterior thighs. - Palpate vertebral column for deformity and areas of tenderness - Assess rectum for presence/absence of tone, presence of blood What she be done after the Secondary Assessment? Reassess: - Primary survey, - VS - Pain - Any injuries What are factors that contribute to ineffective ventilation? - AMS - LOC - Neurologic injury - Spinal Cord Injury - Intracranial Injury - Blunt trauma - Pain caused by rib fractures - Penetrating Trauma - Preexisting hx of respiratory diseases - Increased age What medications are used during intubation? LOAD Mnemonic: L = Lidocaine O = Opioids A = Atropine D = Defasiculating agents What are the Rapid Sequence Intubation Steps? PREPARATION: - gather equipment, staffing, etc. PREOXYGENATION: - Use 100% O2 (prevent risk of aspiration). 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? 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. What is a Laryngeal Mask Airway? 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. What is Needle Cricothyrotomy Percutaneous transtracheal ventilation. (temporary) Complications include: - inadequate ventilation causing hypoxia - hematoma formation - esophageal perforation - aspiration - thyroid perforation - subcutaneous emphysema Some causes: - MI - Blunt cardiac injury - Mitral valve insufficiency - dysrhythmias - Cardiac Failure Explain Obstructive Shock. Results from inadequate circulating blood volume because of an obstruction or compression of great veins, aorta, pulmonary arteries, or heart itself. 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. 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? 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? 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. 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. 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. 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. 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 someone in hypovolemic shock? (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)
