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 What is Surgical Cricothyrotomy? - ✔✔Making an incision in cricothyroid membrane and placing a cuffed endo or trach tube into trachea. This is indicated when other methods of airway management have failed and pt cannot be adequately ventilated and oxygenated.Complications include: - Aspiration - Hemorrhage or hematoma formation or both - Lac to trachea or esophagus - Creation of a false passage - Laryngeal stenosis How do you confirm ET Tube/Alternative Airway Placement? - ✔✔- Visualization of the chords - Using bronchoscope to confirm placement - Listening to breath sounds over the epigastrum and chest walls while ventilating the pt - CO2 detector - Esophageal detection device - Chest x-ray How do you inspect the chest for adequate ventilation? - ✔✔Observe: - mental status - RR and pattern - chest wall symmetry - any injuries - patient's skin color (cyanosis?) - JVD or tracheal deviation? (Tension pneumothorax) What are you looking for when auscultating lung sounds? - ✔✔Absence of BS: - Pneumothorax - Hemothorax - Airway Obstruction Diminished BS: - Splinting or shallow BS may be a result of painWhat are you looking for when percussing the chest? - ✔✔Dullness: - hemothorax Hyperresonance - Pneumothorax What are you looking for when palpating the chest wall, clavicles and neck? - ✔✔- Tenderness - Swelling - subcutaneous emphysema - step-off deformities = These may indicate: esophageal, pleural, tracheal or bronchial injuries. Palpate trachea above suprasternal notch. Tracheal deviation may indicate a tension pneumothorax or massive hemothorax. What is the DOPE mnemonic? - ✔✔D - Displaced tube O - Obstruction: Check secretions or pt biting tube P - Pneumothorax: Condition may occur from original trauma or barotrauma from ventilator E - Equipment failure: pt may have become detached from equipment or there's a kink in the tubing Explain Hypovolemic Shock. - ✔✔Most common to affect a trauma pt cause by hypovolemia.. Hypovolemia, a decrease in amount of circulating blood volume, may result from significant loss of whole blood because of hemorrhage or from loss of semipermeable integrity of cellular membrane leading to leakage of plasma and protein from intravascular space to the interstitial space (as in a burn). Some causes: - Blood loss - Burns, etc. Explain Cardiogenic Shock. - ✔✔Syndrome that results from ineffective perfusion caused by ineffective perfusion caused by inadequate contractility of cardiac muscle.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) - 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? - ✔✔1. Brain2. 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? - ✔✔- Headache - N/V - Amnesia regarding events around the injury - Altered LOC - Restlessness, drowsiness, changes in speech, or loss of judgement What are the late observable signs of symptoms of increased ICP? - ✔✔- Dilated, nonreactive pupil - Unresponsiveness to verbal or painful stimuli - Abnormal motor posturing patterns - Widening pulse pressure - Increased systolic blood pressure - Changes in RR and pattern - Bradycardia What is Cushing's phenomenon or Cushing's Reflex? - ✔✔Triad of progressive HTN, bradycardia and diminished respiratory effort. What are the two types of herniation that occurs with ICP? - ✔✔1. Uncal herniation2. Central or transtentorial herniation Why does herniation occur? What are the symptoms? - ✔✔Because of uncontrolled increases in ICP. S/E's - Unilateral or bilateral pupillary dilation - AsyDimmetric pupillary reactivity - Abnormal motor posturing - Other evidence of neurologic deterioration Define uncal herniation. - ✔✔The uncus (medial aspect of the temporal lobe) is displaced over the tentorium into the posterior fossa. This herniation is the more common of the two types of herniation syndromes. Define central or transtentorial herniation. - ✔✔A downward movement of the cerebral hemispheres with herniation of the diencephalon and midbrain through the elongated gap of the tentorium. Disruptions of the bony structures of the skull can result in what? - ✔✔Displaced or nondisplaced fx's causing CSF leakage b/c of lac to the dura mater, creating a passage for CSF. CSF leaks through the nose (rhinorrhea) or the ears (otorrhea). A potential entrance for invading bacteria. Also: meningitis or encephalitis or brain abscess Define Minor Head Trauma. - ✔✔GCS 13-15 Define Moderate Head Trauma - ✔✔Postresuscitative state with GCS 9-13. Define Severe Head Trauma. - ✔✔Postresuscitative state with GCS score of 8 or less.What is a concussion and its signs and symptoms? - ✔✔A temporary change in neurologic function that may occur as a result of minor head trauma. S/S: - Transient LOC - H/A - Confusion and disorientation - Dizziness - N/V - Loss of memory - Difficulty with concentration - Irritability - Fatigue What are the signs and symptoms of postconcussive syndrome? - ✔✔- Persistent H/A - Dizziness - Nausea - Memory impairment - Attention deficit - Irritability - Insomnia - Impaired judgement - Loss of libido - Anxiety - Depression What is diffuse axonal injury and its signs and symptoms? - ✔✔(DAI) is widespread, rather than localized, through the brain. Diffuse shearing, tearing and compressive stresses from rotational or accerleration/deceleration forces resulting in microscopic damage primarily to axons within the brain. S/S: - Immediate unconsciousne [Show More]
