Where are you putting that Mars Bar?

I saw a recent suggestion that rectal administration of a chocolate bar could be used to reverse hypoglycaemia in a patient who was unable to take anything orally. This led to a range of comments from colleagues mostly of surprise. There were the suggestions that maybe a Poly Woffle has a better likeness to a […]

Thyroid Storm

Thyroid StormThyroid disease is a common consideration for the ill adult patient, but not as commonly considered in children.  That being stated, we have mentioned several conditions which may be related to thyroid disease in children (ex, Bulging Fontanelle, Fever of Unknown Origin, Bradycardia, Down’s Syndrome, Hypothermia in Neonate, and Hypertensive Crisis).  So, it obviously can be a significant issue, but rather challenging to diagnosis if we don’t consider it.  This is particularly true when managing the critically ill child.  Let us now consider Thyroid Storm.

 

Thyroid Storm: Basics

  • Thyroid hormone influences almost every tissue. [Bahn, 2011]
  • Cellular actions of thyroid hormone are mediated by T3, the active form of the hormone.
  • Thyrotoxicosis / Hyperthyroidism 
    • Thyrotoxicosis – clinical state resulting from high thyroid hormone action due to inappropriately high tissue hormone level. [Bahn, 2011]
    • Hyperthyroidism – a form of thyrotoxicosis due to high synthesis and secretion of thyroid hormone(s) by the thyroid gland. [Bahn, 2011]
    • Hyperthyroidism prevalence in USA – ~1% [Bahn, 2011]
    • Median age of onset of hyperthyroidism = ~11 years
    • CNS symptoms often prevalent in children with hyperthyroidism (adults often with more Cardiac symptoms).
      • Tremor, hyperreflexia
      • Anxiety and fragile emotional states
      • Frequent bowel movements
  • Thyroid Storm is a severe form of thyrotoxicosis.
    • Life-threatening crisis that requires rapid assessment and management.
    • Can lead to overt hemodynamic instability.
    • Since it’s symptoms can be similar to other critical illnesses (ex, sepsis, toxic ingestion), it take vigilance and active consideration to diagnosis it promptly.
    • ~1-2% of patients with hyperthyroidism will experience a thyroid storm event.

 

Thyroid Storm: Presentation

  • Individual symptoms are not often specific.
    • Fever, diaphoresis, weakness
    • Nausea, vomiting, abdominal pain
    • Tachycardia, hypertension
    • Extreme anxiety, confusion, altered mental status, seizures, coma
    • High-out congestive heart failurearrhythmias 
    • Hypotension may develop late
  • Characterized by MULTIsystem involvement! (remember the thyroid hormone influences nearly every organ system)
  • High index of suspicion is needed – keep it high on Ddx of patient with thyrotoxicosis and decompensation. [Bahn, 2011, Ureta-Raroque, 1997]
  • There is a Point Scale for the Diagnosis – see [Bahn, 2011]

 

Thyroid Storm: Precipitants

  • Often the precipitating cause of the Thyroid Storm can, itself, produce symptoms similar to the Thyroid Storm, making it challenging to consider.
  • Infection, Trauma and Surgery are commonly associated with Thyroid Storm.
  • Other physical or emotional stressors can lead to Thyroid Storm.
    • Anesthesia
    • Uncontrolled diabetes
    • Pre-eclampsia/eclampsia 
    • Medical reaction / side-effect (ex, taking over the counter cold-preparation medications) [Ureta-Raroque, 1997]
    • Abrupt cessation of antithyroid Rxs
    • Exogenous thyroid hormone ingestion [Majlesi, 2010]
    • Rarely following radioactive iodine therapy [Rohrs, 2014; Bahn, 2011]
    • Exposure to iodine-containing contrast (decompensation after CT??)

 

Thyroid Storm: Therapy

  • Multimodality approach is recommended. [Bahn, 2011]
  • Beta-Adrenergic Blockade
    • Propanolol – thought to also block peripheral conversion of T4 to T3.
    • Esmolol is an alternative
  • Antithyroid Drug Therapy
    • Proplthiouracil (PTU)
      • Blocks new hormone synthesis AND peripheral conversion of T4 to T3
      • In patients with Graves Disease, use has been associated with Hepatotoxicity and, therefore, not recommended. [Glinoer, 2012]
    • Methimazole – Blocks new hormone synthesis. Do NOT use in pregnancy.
  • Inorganic Iodine
    • Potassium iodine (ex, SSKI) – Blocks synthesis and release of hormone.
    • May use Lithium if patient has allergy to iodine.
    • Start 1 hour AFTER giving Antithyroid Rx [Bahn, 2011]
  • Corticosteroids
    • Stress dose Hydrocortisone or Dexamethasone.
    • May block peripheral conversion of T4 to T3
    • Used to empirically treat possible adrenal suppression.
  • Supportive Measures
    • Aggressive Cooling Measures
      • Acetaminophen
      • Cooling blankets and ice packs!
    • Volume Resuscitation
    • Respiratory Support
    • Treat heart failure and/or arrhythmia
  • Treat Precipitating Events
    • Don’t overlook the issue that caused the decompensation.
    • Consider empiric antibiotics if unclear inciting event.

 

Moral of the Morsel

  • While the critically ill child will appropriately generate concern for the usual suspects (ex, Sepsis, Hypovolemia, Mechanical Obstruction, Cardiogenic, Adrenal Crisis, Intussusception/Bowel injury), don’t overlook the potential for other offenders!
  • History of conditions related to thyrotoxicosis should raise your concern!
  • Feel the anterior neck too… maybe you’ll just find the answer when you palpate an enlarge thyroid gland. (see case described by Ureta-Raroque, 1997)
  • As always… be Vigilant!

Aairwayjawthrust

Pediatric airway management is a skill that integrates the three types of knowledge as described by the ancient Greeks:

Episteme — theoretical knowledge

Techne — technical knowledge

Phronesis — practical wisdom — also called prudence.

Here we’ll invoke each type of knowledge and understanding as we go beyond the anatomical issues in pediatric airway management – to the advanced decision-making aspect of RSI and the what-to-do-when the rubber-hits-the road.

 

Case 1: Sepsis

Laura is a 2-month-old baby girl born at 32 weeks gestational age who today has been “breathing fast” per mother.  On arrival she is in severe respiratory distress with nasal flaring and intercostal retractions.   Her heart rate is 160, RR 50, oxygen saturation is 88% on RA.  She has fine tissue-paper like rales throughout her lung fields.  Despite a trial of a bronchodilator, supplemental oxygen, even nasal CPAP and fluids, she becomes less responsive and her heart rate begins to drop relatively in the 80s to 90s – this is not a sign of improvement, but of impending cardiovascular collapse.

She is in respiratory failure from bronchiolitis and likely viral sepsis.  She needs her airway taken over.

Is this child stable enough for intubation?

We have a few minutes to optimize, to resuscitate before we intubate.

Here’s an easy tip: use the sterile flushes in your IV cart and push in 20, 40, or 60 mL/kg NS.  Just keep track of the number of syringes you use – it is the fastest way to get a meaningful bolus in a small child.

Alternatively, if you put a 3-way stop-cock in the IV line and attach a 30 mL syringe, you can turn the stop cock, draw up stream from the IV bag into the syringe, turn te stop cock, and push the fluid in the IV.

Induction Agent in Sepsis

The consensus recommendation for the induction agent of choice for sepsis in children is ketamine.

Etomidate is perfectly acceptable, but ketamine is actually a superior drug to etomidate in the rapid sequence intubation of children in septic shock.  It rapidly provides sedation and analgesia, and supports hemodynamic stability by blocking the reuptake of catecholamines.

Paralytic Agent in Sepsis

The succinylcholine versus rocuronium debate…

Succinylcholine and its PROS

Succinylcholine and its CONs

  • Raises serum potassium in everyone, typically 0.5 to 1 mEq/L.  That is not usually a problem, but for those with preexisting or inducible hyperkalemia, it can precipitate an arrest, as in renal failure, underlying neurologic or myopathic conditions like multiple sclerosis, muscular dystrophy, ALS, or those who had a stroke or a burn more than 72 hours prior. We often have limited information in critical situations.
  • Succinylcholine gives us a false sense of security.  In children, there really is no “safe apnea” period.
  • Succinylcholine’s effect on the nicotinic receptors results in mydriasis, tachycardia, weakness, twitching and hypertension, and fasciculations (Think nicotine overdose: M/T/W/Th/F).
  • Succinylcholine’s effect on muscarinic receptors manifest (as in organophosphate overdose): SLUDGE – salivation, lacrimation, urination, defecation, GI upset or more apropos here: DUMBBELLS – diarrhea, urination, miosis, bradycardia, emesis, lacrimation, lethargy, salivation.
  • Second dose of succinylcholine – beware of the muscarinic effects and bradycardia. Co-administer atropine, 0.01 mg/kg, up to 0.5 mg IV.

Coda: succinylcholine is not that bad – we would not have had such great success with it during the early years of our specialty if it were such a terrible drug.  The side effects are rare, but they can be deadly.  So, what’s the alternative?

Rocuronium and its PROs

  • It has none of the side-effects of succinylcholine

Rocuronium and its CONs

  • Argument 1: the duration is too long if there is a difficult airway, since rocuronium can last over an hour.
    Still need to intubate, and now your patient is potentially worse.
  • Argument 2: succinylcholine produces better intubating conditions at 45 seconds compared to rocuronium.
    At 0.6 mg/kg, rocuronium is inferior to succinylcholine at all time intervals. At 1.0 mg/kg, rocuronium is still inferior at 45 seconds.  1.2 mg/kg rocuronium is the dose now commonly recommended; per a study byHeier et al. in Anesthesia and Analgesia in 2000, rocuronium produced excellent intubating conditions in higher doses.

Case 2: Multitrauma

Joseph is a 3-year-old boy who is excited that there are so many guests at his home for a family party and when it’s starting to wind down and the guests begin to leave, he is unaccounted for.  An unsuspecting driver of a mini-van backs over him.

He is brought in by paramedics, who are now bagging him.

Induction Agent in Trauma

  • Need something that is hemodynamically stable – agents such as midazolam or propofol would cause too many problems.
  • Etomidate is a short-acting imidazole derivative that acts on GABA-A receptors to induce loss of consciousness in 5-15 seconds. It can cause apnea, pain on injection, and myoclonus.
  • Etomidate reduces cerebral blood flow, reduces intracranial pressure, and reduces cerebral oxygen consumption, all while maintaining arterial blood pressure and cerebral perfusion pressure.
  • Ketamine is reasonable as well: there is no contraindication to ketamine except for known hydrocephalus. It is safe in head trauma.  It is a good choice for the hypotensive trauma patient.  TBI is not a contraindication.
  • In the case of the critically injured child who is normotensive, ketamine will raise his blood pressure and perhaps foster further bleedingThe goal is a good general perfusion and a balanced resuscitation, ensuring enough cerebral perfusion without disrupting nascent clots.  On the other side of the spectrum, permissive hypotension is not described in children, as hypotension is a late and dangerous sign of shock.

Paralytic Agent in Trauma

Are your surgeons in an uproar about a long-acting agent and the pupillary response?  Relax, it’s a myth.

Caro et al. in Annals of Emergency Medicine in 2011 reported that the majority of patients undergoing RSI preserved their pupillary response.  Succinylcholine actually performed worse than rocuronium.  In the rocuronium group, all patients preserved their pupillary response.

In the critically ill, rethink your dosing of both the sedative and the paralytic.

In a critically ill child or adult, perfusion suffers and it affects how we administer medications.  The patient’s arm-brain time or vein-to-brain time is less efficient; additionally, as the patient’s hemodynamic status softens, he becomes very sensitive to the effects of sedatives.

We need to adjust our dosing for a critically ill patient:

Decrease the sedative to avoid falling over the hemodynamic compensation cliff.

Increase the paralytic to account for prolonged arm-brain time.


Case 3: Cardiac/myocarditis/congenital heart disease

Jacob is a 6-year-old-boy with tricuspid atresia s/p Fontan procedure who’s had one week of runny nose, cough, and now 2 days of high fever, vomiting, and difficulty breathing.

The Fontan procedure is the last in a series of three palliative procedures in a child with complex cyanotic congenital heart disease with a single-ventricle physiology.

The procedure reroutes venous blood to flow passively into the pulmonary arteries, because the right ventricle has been surgically repurposed to be the systemic pump.  The other most common defect with an indication for a Fontan is hypoplastic left heart syndrome.

Typical “normal” saturations for post-operative CHD can be 75 and 85% on RA.  The Fontan procedure improves saturations, which are typically 88-95%.  Ask the parents or caregiver.

Complications of the Fontan procedure include heart failure, superior vena cava syndrome, hypercoagulable state, and others.
A patient with a Fontan can present in cardiogenic shock from heart failure, distributive shock from an increased risk of infection, hypovolemic shock from over-diuresis or insensible fluid loss – or just a functional hypovolemia from the fact that his venous return is all passive – and finally obstructive shock due to a pulmonary thromboembolism.

Types of shock: this is how people COHDeCardiogenic, Obstructive, Hypovolemic, Distributive.

Do we give fluids?

Children after palliative surgery for cyanotic heart disease are volume-dependent.  Even if there is a component of cardiogenic shock, they need volume to drive their circuit.  Give a test dose of 10 mL/kg NS.

Pressors in Pediatric Shock

  • Children compensate their shock state early by increasing their SVR.
  • Epinephrine (adrenaline) is great at increasing the cardiac output (with minimal increase in systemic vascular resistance; tachycardia)  In children the cardiac deleterious effects are not pronounced as in adults.  Later when the child is stabilized, other medication such as milrinone (ionotrope and venodilator) can be used.
  • Epinephrine is also fantastic for cold shock when the patient is clamped down with cold extremities – the most common presentation in pediatric septic shock.
  • Norepinephrine (noradrenaline) is best used when you need to augment systemic vascular resistance, such as in warm shock, where the patient has loss of peripheral vascular tone.

Induction Agent in Cardiogenic Shock

A blue baby – with a R –> L shuntneeds some pinking up with ketamine

A pink baby – with a L –> R shunt – is already doing ok – don’t rock the boat – give a neutral agent likeetomidate.

Myocarditis or other acquired causes of cardiogenic shock – etomidate.  Ketamine is an acceptable alternative, but watch for tachydysrythmias.

Case 4: Status Epilepticus

Jessica is a 10-year-old girl with Lennox-Gastaut syndrome who arrives to your ED in status epilepticus.  She had been reasonably controlled on valproic acid, clonazepam, and a ketogenic diet, but yesterday she went to a birthday party, got into some cake, and has had stomach aches – she’s been refusing to take her medications today.

On arrival, she is hypoventilating, with HR 130s, BP 140/70, SPO2 92% on face mask.  She now becomes apneic.

Induction Agent in Status Epilepticus

Many choices, but we can use the properties of a given agent to our advantage. She is normo-to-hypertensive and tachycardic.  She has been vomiting. A nice choice here would be propofol.

  • Propofol as both a sedative and anti-epileptic agent works primarily on GABA-A and endocannabinoid receptors to provide a brief, but deep hypnotic sedation.  Side effects can include hypotension, which is often transient and resolves without treatment.  Apnea is the most common side-effect.
  • Ketamine would be another good choice here, for its anti-epileptic activity.

Paralytic Agent in Status Epilepticus

Rocuronium (in general), as there are concerns of a neurologic comorbidity.

Housekeeping in RSI

What size catheter do I use?  Based on ETT size, it is just a matter of multiplication by 2, 3, or 4.

Remember this: 2, 3, 4 – Tube, Tape, Tap

The NG/OG/Foley is 2 x the ETTtube

The ETT should be secured at a depth of 3 x the ETT sizetape

A chest tube size 4 x the ETTtap

In summary, in these cases of sepsis, multitrauma, cardiogenic shock, and status epilepticus:

  • Resuscitate before you intubate
  • Use the agent’s specific properties and talents to your benefit
  • Adjust the dose in critically ill patients: decrease the sedative, increase the paralytic
  • Have post-intubation care ready: analgesia, sedation, verification, NG/OG/foley
