#1: Vital signs in childrenThe heart rate (per minute) is defined depending upon age and if the child is awake or asleep.
- Newborns up to 3 months old, the heart rate is 85–205 while awake and 80–160 while asleep.
- Age 3 months to 2 years old, the heart rate changes and becomes 100–190 while awake and 75–160 while asleep.
- The heart rate begins to fall between the ages of 2 to 10, and becomes 60–140 while awake and 60–90 while asleep.
- Falling further, children aged 10 years and above become 60–100 while awake and 50–90 while asleep.
Respiratory rate (breath per minute) has a similar progression.
- Infant, 30–60.
- Toddler, 24–40.
- Preschooler, 22–34.
- School-aged, 18–30.
- Adolescent, 12–16.
Hypotension in children is determined by age and systolic blood pressure (BP), measured in mmHg.
- Term neonates (0 to 28 days): The systolic BP is < 60 mmHg.
- Infants (1 to 12 months): Systolic BP is < 70 mmHg.
- Children 1 to 10 years (5th BP percentile): Systolic BP is *< 70 mmHg + (age in years x 2).
- Children > 10 years: Systolic BP is < 90 mmHg.
*For example, you use the following calculation to determine hypotension by systolic blood pressure for a 7 year old:
70 mmHg + (7 years of age x 2)
70 mmHg + (14)
Therefore, a 7-year-old child is hypotensive when the systolic blood pressure is less than 84 mmHg.
Modifications in glasgow coma scale for infants and children eye opening:
- For spontaneous eye opening, the score is 4 in both children and infants.
- If eye opening involves speech, the score is 3 for both.
- If eye opening is with pain, the score is 2 in both.
- If there is no eye opening, the score is 1 in both.
Scoring pattern for verbal response:
- The score is 5 if the verbal response is oriented and appropriate in children; and is 5 with coos and babbles in infants.
- The score becomes 4 for confusion in children and irritable caries in infants.
- The score is 3 if children respond with inappropriate words and infants cry in response to pain.
- Making of incomprehensible sounds by children and moaning in response to pain by infants lowers the score to 2.
- If there is no verbal response, the score becomes 1 in both.
Scoring pattern for motor response:
- The score is 6 in children obeying commands and in infants showing purposeful and spontaneous movements.
- The score is 5 in children who vocalizes due to painful stimuli and in infants withdrawing with touch.
- The score is 4 in both children and infants withdraw due to pain.
- The score is 3 in children whose flexion is in response to pain and in infants showing abnormal flexion posture due to pain.
- The score is 2 in children who show extension during pain and in infants showing abnormal extension posture due to pain.
- The score is 1 in both the absence of any motor response.
#2: Summary of steps of cardiopulmonary resuscitation (CPR) for adults, children, and infantsThis algorithm outlines the differences between the CPR steps in adults, children, and infants.
- Recognition of unresponsiveness for adults involves absence of normal breathing, any breathing, or gasping. Recognition for children and infants is gasping or no breathing.
- In all the age groups if no pulse is felt within the first 10 seconds, the CPR sequence should be initiated—compressions of the chest, providing airway, and breathing (C-A-B).
- The compression rate should be at least 100/min for both children and adults.
- For adults, the depth of compression should be at least 2 inches (5 cm); for children, it should be 1/2 of anterior-posterior chest diameter or about 2 inches; for infants, it is at least 1/3 of the anterior-posterior chest diameter or about 1 and 1/2 inches (4 cm).
- In all the age groups, the chest should be allowed to recoil completely between compressions.
- The compressors may be rotated in 2 minutes intervals. Interruptions between compressions should be minimized as much as possible and should be restricted to less than 10 seconds.
- Airway may be provided through a head-tilt-chin-lift method while in case of suspected trauma, the jaw-thrust method should be used. Until the placement of advanced airway, the compression to ventilation ratio should be maintained at 30:2 (with 1-2 rescuers in action) for adults; for children and infants, the ratio needs to be at 30:2 (single rescuer in action) while 15:2 (2 rescuers in action).
- For all the age groups, with advanced airway in place, 8-10 breaths/min should be provided, that is 1 breath every 6–8 seconds. The breathing needs to be asynchronous with chest compressions, around 1 second per breath with visible rise in chest.
- As soon as available, the AED leads should be attached and put to use. Before and after shock, interruptions between chest compressions should be minimized. Immediately following each shock, CPR should be resumed with chest compressions.
#3: Pediatric septic shock Algorithm
This algorithm outlines the steps required for the care of children with septic shock.
Assess the child and recognize any change in the mental status or perfusion, blood flow through the circulatory system. The child should be provided with adequate ventilation and oxygen while establishing vascular access. Resuscitation should be immediately initiated as per the guidelines of PALS.
Ionized calcium, lactate, glucose, arterial blood gasses (ABG) or venous blood gasses (VBG), complete blood count (CBC), and cultures may also be considered.
In the first hour of septic shock, repeated isotonic crystalloid boluses are administered at 20 mL/kg to the child. If no respiratory distress, rales (small clicking, bubbling, or rattling sounds in the lungs), or hepatomegaly (enlarged liver); 4 or more boluses may be given.
Hypocalcemia and hypoglycemia need to be corrected.
The first dose of antibiotics should be administered STAT.
Consideration for ordering stress-dose hydrocortisone and STAT vasopressors drip may be made. If there is anticipation for a vasoactive infusion, a second vascular site needs to be established.
After the first hour, if the child shows a response to fluid administration (i.e., hemodynamics or normalized perfusion); ICU monitoring may be considered. However, if the child is not responsive to fluid, then therapy with vasoactive drugs should be initiated and titrated for the correction of poor perfusion or hypotension. Consideration of central and arterial venous access is warranted.
If the child is normotensive, having a normal BP, then therapy may begin with dopamine; norepinephrine may be considered if the child is hypotensive with vasodilated (warm) shock; norepinephrine may be replaced with epinephrine if the child is hypotensive with vasoconstricted (cold) shock.
Following vasoactive drug therapy, venous oximetry should be performed to check for central venous oxygen saturation (ScvO2). Generally, for warm shock, if the ScvO2 ≥ 70% with low BP, additional boluses of norepinephrine should be given with or without vasopressin. Generally, for cold shock, if ScvO2 < 70% with poor perfusion and low BP, a blood transfusion may be given (generally not indicated when the hemoglobin (hgb) concentration is above 10 g/dL) while optimizing arterial oxygen saturation. Additional boluses of fluid may be considered, either dobutamine along with norepinephrine or epinephrine alone may be considered.
Adrenal insufficiency is suspected if the child shows fluid-refractory shock. In such condition, baseline cortisol should be drawn and stimulation with adrenocorticotropic hormone (ACTH) should occur. Tests may be carried out if not sure of the steroid needs. Hydrocortisone (around 2 mg/kg bolus up to a maximum of 100 mg) may be given when adrenal insufficiency is suspected.

#5: Drugs used in PALS (Continued)
This algorithm outlines the doses and indications for the different drugs used in the treatment of children.
Etomidate: is indicated for the treatment of repetitive strain injury (RSI). It is used as an infusion of 0.2–0.4 mg/kg IV/IO over a period of 30–60 seconds with a maximum dose of 20 mg. This dosage is good enough to produce a sedative effect lasting 10–15 minutes.

Lidocaine: is indicated in VF/pulseless VT and in wide complex tachycardia at a bolus of 1 mg/kg IV/IO. Maintenance should be an infusion of 20–50 mcg/kg IV/IO per minute; the bolus dose may be repeated if infusion is started after 15 minutes after the initial bolus. If intubated, dose should be 3–5 mg/kg ET.
Magnesium sulfate: is indicated in asthma (refractory status asthmaticus), hypomagnesemia, and torsades de pointes. For treating pulseless VT, a bolus dose of 25–50 mg/kg IV/IO up to a maximum dose of 2 g may be given; the treatment should be over 10–20 minutes for VT with pulses; and for treating asthma, it should be carried out with a slow infusion over 15–30 minutes.
Methylprednisolone: is indicated in asthma (status asthmaticus) and anaphylactic shock. The dose should be 2 mg/kg IV/IO/IM up to a maximum of 60 mg while methylprednisolone acetate should only be given IM; the maintenance is at 0.5 mg/kg IV/IO for 6 hours duration up to a maximum of 120 mg.
Milrinone: is indicated during increased SVR/PVR and myocardial dysfunction. The loading dose should be 50 mcg/kg IV/IO over 10–60 minutes, which may be followed by an infusion of 0.25–0.75 mcg/kg per minute IV/IO.
Naloxone: is used in the reversal of narcotic (opiate). For total reversal (i.e., secondary to overdose narcotic toxicity), subcutaneous bolus dose of 0.1 mg/kg IV/IO/IM is given for 2 minutes up to a maximum of 2 mg. If total reversal is not needed (i.e., therapeutic narcotic induced respiratory depression), subcutaneous dose of 1–5 mcg/kg IV/IO/IM is given and titrated to the desired effect. In order to maintain reversal, an infusion of 0.002–0.16 mg/kg per hour IV/IO is used.
Nitroglycerin: is indicated in cardiogenic shock and congestive heart failure. The drug is given as an infusion initially at 0.25–0.5 mcg/kg per minute IV/IO and as per tolerance titrated by 1 mcg/kg per minute for a period of 15–20 minutes. The usual dose range is 1–5 mcg/kg per minute with a maximum dose of 10 mcg/kg per minute. The dose should begin at 5–10 mcg per minute in adolescents with a maximum dose of 200 mcg per minute.
Nitroprusside: is indicated in severe hypertension and cardiogenic shock (associated with high SVR). The initial dose should be given at 0.3–1.0 mcg/kg per minute and titrated up as needed to 8 mcg/kg per minute.
Norepinephrine: is indicated in hypotensive shock (i.e., fluid refractory and low SVR) and used as an infusion of 0.1–2 mcg/kg per minute, titrated to the desired effect.
Procainamide: is indicated in VT (with pulses), SVT and atrial flutter; and given at a dose of 15 mg/kg IV/IO over 30–60 minutes. However, it should not be routinely used in combination with amiodarone.
Prostaglandin E1 (PGE1): is used in all forms of ductal-dependent congenital heart disease and given initially in an infusion of 0.05–0.1 mcg/kg per minute and then followed by 0.01–0.05 mcg/kg per minute IV/IO.
Sodium bicarbonate: is indicated in hyperkalemia and severe metabolic acidosis. It is administered as a slow bolus of 1 mEq/kg IV/IO; in the overdose of a sodium channel blocker (e.g., tricyclic antidepressant) a bolus dose of 1–2 mEq/kg IV/IO is used until the serum pH is greater than 7.45 (for cases of severe poisoning, it should be between 7.5–7.55). This is followed by an infusion of 150 mEq IV/IO NaHCO3/L solution and titrated for maintaining alkalosis.
Terbutaline: is indicated in hyperkalemia and asthma (status asthmaticus). An infusion dose of 0.1–10 mcg/kg per minute IV/IO while considering a bolus of 10 mcg/kg IV/IO over 5 minutes.

#6: Pediatric cardiac arrest Algorithm
The pediatric cardiac arrest algorithm outlines the steps of care and management of infants with cardiac arrest.
Upon finding a child in cardiac arrest, one should shout for help and immediately activate the emergency response team. Meanwhile, initiate CPR, attach AED leads, and provide oxygen. If the rhythm is Ventricular Fibrillation (VF)/Ventricular Tachycardia (VT) then provide shock followed by CPR for 2 min along with IO/IV access. At this stage, a second shock may be given followed by another round of CPR for 2 min along with the administration of epinephrine every 3–5 min. Advanced airway may also be considered. Again, if the rhythm is shockable, another shock may be given followed by CPR for 2 min along with amiodarone administration.
However, if the rhythm is asystole or pulseless electrical activity (PEA) then no shock should be given. Instead, CPR should be administered for 2 min along with the provision of IO/IV. Epinephrine may be given every 3–5 min and advanced airway may be considered. If after this stage, the rhythm becomes shockable, shock is administered, followed by CPR. If the same rhythm persists, continue CPR for 2 min.
The assessment should be made based on the rhythm detected. If the AED shows an organized rhythm, pulse should be checked. If the pulse is present, post-cardiac arrest care should be given.
#7: Details and doses of the pediatric cardiac arrest Algorithm
Quality of CPR: pushing should be at least 1/2 of the anterior-posterior chest diameter to allow a complete recoil of the chest. Interruptions between compressions should be minimized as much as possible, while avoiding excessive ventilation. In every 2 minute interval, compressor may be rotated. In absence of any airway, the compression-ventilation ratio is 15:2, while in presence of advanced airway, continuous chest compressions and 8–10 breaths per minute should be maintained.
Defibrillation (unsynchronized cardioversion—high energy shock): the first shock is of 2 J/kg followed by 4 J/kg (second shock). Subsequent shocks should be greater than 4 J/kg but not more than 10 J/kg.
Drug therapy: epinephrine IO/IV dosage: 0.01 mg/kg (0.1 mL/kg of 1:10000 concentration) may be administered; repeated after each 3–5 minutes. ET dose may be given (0.1 mg/kg) if IO/IV access is unavailable and endotracheal tube is in place.
Amiodarone IO/IV dosage: during cardiac arrest, 5 mg/kg bolus is given, which may be repeated for pulseless VT or refractory VT up to 2 times.
Provisions of advanced airway: supraglottic advanced airway or endotracheal airway may be warranted. A capnometry or waveform capnography may be used for confirming and monitoring the placement of endotracheal tube. One breath every 6–8 seconds should be given once the advanced airway is in place (i.e., 8–10 breaths per minute).
Provisions of ROSC (return of spontaneous circulation): pulse and blood pressure are present. Intra-arterial monitoring shows the presence of spontaneous arterial pressure waves.
Reversible causes include: acidosis (hydrogen ion), hypoxia, hypovolemia, hypothermia, hypo/hyperkalemia, hypoglycemia, toxins, cardiac tamponade, pneumothorax tension, coronary thrombosis, and pulmonary thrombosis.
#8: PALS systematic approach Algorithm
The PALS systematic approach algorithm outlines the steps required for the caring of a critically injured or ill child.
The initial assessment includes color, breathing, and consciousness. If the child is unresponsive with only gasping and no breathing, then the caregiver should immediately shout for help and activate emergency response. If there is a pulse, airway should be opened and the child provided with oxygen and ventilation support as needed. If the pulse is <60/min, and the patient shows signs of poor perfusion despite adequate oxygenation and ventilation, CPR should be immediately initiated.
Also, if there is no pulse, CPR (C-A-B) should be initiated, followed by pediatric cardiac arrest algorithm. Following ROSC, the evaluate-identify-intervene sequence should be initiated—the evaluation stage includes primary and secondary assessments and diagnostic tests. If the child shows signs of breathing during the initial assessment then the sequence of evaluate-identify-intervene sequence should be started thereof. If cardiac arrest is identified at any point during this process, then CPR should be started.
#9: Pediatric bradycardia with a pulse and poor perfusion Algorithm
This algorithm outlines the evaluation and care for bradycardia in children with the presence of a pulse and poor perfusion.
In such cases, the first step should be the identification of the underlying cause and its subsequent treatment. A patent airway should be maintained along with assisted breathing or oxygen as necessary. Heart rhythm should be identified along with monitoring blood pressure and oximetry. If available, proceed with a 12-lead ECG without delaying therapy. IV/IO access is required.
If the child is no longer in a state of cardiopulmonary compromise (as indicated by symptoms of shock, hypotension, or acutely altered mental status), then the child may be put under supportive observation and provided with oxygen while awaiting consultation with an expert healthcare provider.
However, if the cardiopulmonary compromise continues with a heart rate greater than 60/min, despite adequate ventilation and oxygenation, then CPR should be administered. Even after CPR, if the bradycardia persists, epinephrine or atropine (for primary AV block or increased vagal tone) may be administered.
The basic idea should be to treat the underlying cause along with the consideration of transvenous pacing/transthoracic pacing. If bradycardia does not persist, then the patient should be put under observation and supported with ABCs while awaiting consultation with an expert healthcare provider.
Cardiac arrest algorithm may be followed if pulseless arrest develops.
Details of the dosage:
Atropine IV/IO dosage: 0.02 mg/kg may be administered, which may be repeated once more. The minimum dose is 0.1 mg while the maximum dose is 0.5 mg.
Epinephrine IO/IV dosage: 0.01 mg/kg (0.1 mL/kg of 1:10000 concentration) may be administered; repeated after each 3–5 minutes. ET dose may be given (0.1 mg/kg) if IV/IO access is unavailable and endotracheal tube is in place.
#10: Pediatric tachycardia with a pulse and poor perfusion Algorithm
The approach of evaluation and care for tachycardic children with pulse but poor perfusion is as follows.
The first step is identification of the underlying cause and its subsequent treatment. Quickly, a patent airway should be maintained with assisted breathing or with oxygen.
Heart rhythm should be identified along with monitoring blood pressure and oximetry. There should be access to IV/IO. If available, proceed with a 12-lead ECG without delaying therapy.
Next, the QRS duration needs to be assessed. If the duration is narrow (≤ 0.09 sec), then proceed with a 12-lead ECG or monitor the heart rhythm.
Sinus tachycardia is suspected if: consistent with known cause; there is compatible history, constant PR but variable R-R, and P waves are normal or present. For children, the rate is usually greater than 180/min and for infants the rate is generally greater than 220/min. If sinus tachycardia is present, the cause needs to be found and then treatment initiated.
Supraventricular tachycardia is suspected if: there is a history of abrupt rate changes or compatible history (nonspecific, vague); non-variable HR; P waves are absent or abnormal; for children the rate is usually ≥ 180/min and for infants, the rate is generally ≥ 220/min. If it is supraventricular tachycardia, vagal maneuvers should be considered without delay. Adenosine should be administered in presence of access to IV/IO. However, if adenosine is found to be ineffective or there is no IV/IO access, synchronized cadioversion should be considered.
If the QRS duration is wide (> 0.09 sec), ventricular tachycardia is suspected, which may be caused by cardiopulmonary compromise. If that is the reason, then there will be symptoms of shock, hypotension, and acutely changed mental status. In such a case, synchronized cardioversion should be considered. However, if the QRS is monomorphic and the heart rhythm is regular, adenosine may be considered.
Subsequently, one should consult an expert and consider amiodarone or procainamide.
Details of the dosage to be administered:
For synchronized cardioversion (low energy shock): one may initiate with 0.5-1.0 J/kg and increases up to 2 J/kg if the initial dose is found ineffective. Sedation may be provided but without any delays in cardioversion.
For adenosine IV/IO dosage: initiate with a rapid bolus dose of 0.1 mg/kg and increase up to a maximum of 6 mg/kg. This should be followed by a second bolus dose of 0.2 mg/kg and increased up to a maximum of 12 mg/kg.
Procainamide IV/IO dosage: over a duration of 30–60 min, administer 15 mg/kg.
Amiodarone IV/IO dosage: over a duration of 20–60 min, administer 5 mg/kg. However, procainamide and amiodarone should not be routinely administered together.
#11: PALS post-resuscitation care
The PALS management of shock after ROSC algorithm outlines the steps of evaluation and care following cardiac arrest.
Depending on the patient’s hydration status and clinical condition, the composition and rate of intravenous fluid administration may be adjusted after the initial stabilization.
In case of infants, generally a continuous infusion of solution containing dextrose may be provided. For critically ill children, hypotonic solutions should be avoided. For all patients, isotonic solutions, such as lactated Ringer’s with or without dextrose or normal saline (0.9% NaCl), may be provided based on the child's clinical status.
