Special Populations Flashcards
(123 cards)
Define Neonate, Infant, Toddler, Preschool age, school age, and adolescent?
Neonate: first month of life
Infant: 1 month to 12 months
Toddler: 1-2 years
Preschool: 3-5 years
School age: 6-12 years
Adolescent: 13-18 years
What are some nonspecific behaviours that may indicate a serious underlying illness or injury?
Feeding changes
Sleep pattern changes
Ordinary behaviour changes
What is significant about an infant’s head?
An infant’s head is already 2/3 of the size it will be in adulthood
Traumatic brain injury is the leading cause of death and significant disability in pediatrics
What is the paediatric assessment triangle? (PAT)
An assessment tool used for forming a general impression from the doorway.
The triangle includes Appearance, Circulation, Work of breathing.
What is the TICLS mnemonic? What does it mean?
The TICLS mnemonic highlights the most important features of a child’s appearance.
Tone (does the child have good muscle tone)
Interactiveness (how alert is the child)
Consolability (can crying or agitation be relieved)
Look or gaze (does the child fix their gaze on you or is there a vacant stare)
Speech or cry (is the child’s cry spontaneous and strong)
What is the significance of grunting?
Grunting involves exhaling against a partially closed glottis. Lower airway obstructions are suggested by grunting. Grunting may present as a symptom of pneumonia, bronchiolitis, and pulmonary edema.
Define Pallor, Mottling, and Cyanosis?
Pallor: white or pale skin or mucous membranes from inadequate blood flow
Mottling: lacy pattern of skin discolouration
Cyanosis: blue or purple discolouration of skin and mucous membranes
What is a length based resuscitation tape?
A tool used to estimate a child’s weight and identify correct size for pediatric equipment and medication doses
Why might only counting 10-15 seconds give you a falsely low respiratory rate in an infant?
Healthy infants may show periodic breathing or variable respiratory rates with short periods of apnea for less than 20 seconds.
What is the formula for determining the lower limit of acceptable blood pressure for children ages 1-10?
Minimum systolic blood pressure = 70 + (2 x age)
Explain the difference between resp. Distress, resp. Failure, and resp. Arrest?
Resp. Distress: increased work of breathing to maintain oxygenation or ventilation
Resp. Failure: a patient can no longer compensate for the problem causing increased work of breathing
Resp. Arrest: the patient has stopped breathing spontaneously
How do you clear an obstruction in the airway of a responsive infant?
5 back slaps followed by 5 chest thrusts
If the patient becomes unresponsive, start CPR
What is croup? Who and what does it affect?
Croup is a viral infection of the upper airway and the most common cause of upper emergencies in young children. Most commonly affects children ages 6 months to 6 years and most cases occur in the fall and winter. Has an affinity for the subglottic space (narrowest part of the airway).
What is epiglottitis?
Severe inflammation of the supraglottic structures due to bacterial infection.
Rare in children since the introduction of the childhood vaccine against mophilus influenzae type B
How does the pathophysiology of an upper airway emergency differ from a lower airway emergency?
Upper: restriction of airflow into the lungs (inhalation)
Lower: restriction of airflow out of the lungs (exhalation)
How many children are affected by Asthma? What are the 3 components that lead to obstruction and poor gas exchange?
5-10% of children are affected by asthma
The three components leading to obstruction are:
Bronchospasm
Mucous production
Airway inflammation
What is Bronchiolitis?
Inflammation of the bronchioles due to viral infection. Most commonly caused by the respiratory syncytial virus (RSV).
Signs and symptoms are similar to asthma however Bronchiolitis is common in children younger than 2 years and asthma is rare in children less than 1 year old.
What special precautions is taken to align the airway of a child younger than 2 years?
Place a hon layer of padding under the shoulders or upper torso to align the airway
What are the 2 most common ways of delivering oxygen to a a pediatric patient?
Blow by technique or non-rebreathe mask
At what rate should you deliver BVM breaths for infants and children?
12-20 bpm
Avoid excessive tidal volumes to reduce risk of distension, vomiting, and aspiration
Explain the DOPE mnemonic used for troubleshooting a tracheal tube?
Displacement: re-auscultate, if breath sounds are louder in the right pull the tube out slightly, if breath sounds are absent and gurgling is heard remove the tube and BVM with 100% oxygen
Obstruction: if thick secretions interfere with your ability to ventilate perform tracheobronchial suctioning
Pneumothorax: ventilation compliance may be decreased, call ALS for needle decompression, suspect if breath sounds are louder on the left and decreased on the right
Equipment failure: check the reservoir bag, ensure delivery of 100% oxygen
Why is hypovolemic shock the most common type of shock in infants and young children?
Due to their relatively small blood volume (70 ml/kg), excessive fluid loss and poor intake can result in shock relatively quickly.
May be lethargic and appear mottled or cyanotic with compensatory tachypnea.
What are the best sites for IV starts in infants and children?
Hands
Antecubital fossa
Saphenous veins
Ankle and feet
How might a child in disruptive shock appear?
Early: warm flushed skin and bounding pulses
Late: appear similar to hypovolemic shock (lethargic, cyanotic)
