Compensated shock in child

When the cardiopulmonary system can no longer adequately supply the mitochondria with glucose and oxygen to create adenosine triphosphate ATPa shock state has developed.

Because of the decreased glucose or oxygen delivery to the peripheral tissues, the patient can develop central nervous system injuryrespiratory failurerenal or hepatic dysfunctionand gastrointestinal ischemia. If left untreated, shock can be fatal in children. Shock in children can be considered as one of the most common presentations that are life-threatening to the emergency pediatric department.

Mortality increases significantly in children who present with shock compared to those who have the same disease but present without shock. The most common cause of shock in children is sepsis, followed by hypovolemic shock, distributive shock and, finally, cardiogenic shock. The prognosis of children presenting in shock has improved over the last decade, mainly due to the introduction of new classes of antibiotics and our recent advances in the understanding of the pathophysiology of sepsis and septic shock.

Shock can be classified into hypovolemiccardiogenicdistributive and obstructive based on the etiology. This shock is characterized with fluid losses caused by diarrhea and vomiting.

These losses are often exacerbated by decreased oral intake as well. Due to an increase in sympathetic discharge and catecholamine release, peripheral vasoconstriction and tachycardia are often adequate in mild or moderate volume loss to preserve relatively normal blood pressure. The diastolic component of the blood pressure may be the most noticeably decreased. Cardiogenic shock can result from congenital heart diseases or cardiomyopathies.

They are characterized by decreased cardiac output due to impaired systolic function of the heart and not because of decreased filling. This occurs when blood is unable to enter or leave the heart, despite normal intravascular volume and cardiac function. Both cardiac and pulmonary causes exist for obstructive shock, such as cardiac tamponade, tension pneumothorax, pulmonary hypertension, and coarctation of the aorta. The common causes of acute obstruction of pulmonary and systemic blood flow are cardiac tamponade, tension pneumothorax and massive pulmonary embolism.

Children who have either recently completed a prolonged course of steroid therapy or are on chronic steroid replacement therapy are at high risk for endocrinological shock.

The different consequences of shock can be attributed to either the inadequate delivery of substrates, such as glucose and oxygen, or the removal of toxins from peripheral tissues. In a normal physiologic state, the cellular metabolism is dependent on glucose and oxygen where adenosine triphosphate can be generated by the mitochondria via aerobic metabolism and the Krebs cycle.

When shock develops, the body can try to compensate via gluconeogenesis and glycogenolysis, but this is usually a limited compensation that fails. Due to the absence of oxygen in the shock state, pyruvate is converted to lactate instead of acetyl-CoA.

This pathway generates two adenosine triphosphate molecules per one molecule of glucose and is associated with the accumulation of lactate. The inadequate production of adenosine triphosphate and the production of lactate at the cellular level is associated with impaired cell membrane ion pump function and acidosis. Cellular edema eventually happens and cellular death can ensue if the shock state is not corrected.

Therefore, for cellular shock to happen, an impairment must occur in local tissue blood flow, the content of oxygen in the delivered blood, or the degree of oxygen demand in the peripheral tissue. In normal physiologic states, we can compensate to increased oxygen demand by increasing the heart rate and the cardiac stroke volume. In shock states, we might try to compensate to the increased oxygen demand by increasing the oxygen extraction ratio but the total arterial flow of oxygen becomes less controlled.

Increasing oxygen extraction usually fails in shock state and is associated with the accumulation of lactate in the blood and in hypoxic injury to the cells. An important part of history-taking in a child who presents with shock is the identification of the etiology of shock. Children who present with vomitingdiarrhea or both and have shock most likely have hypovolemic shock due to intravascular fluid loss.Make EMS1 your homepage.

When shock is suspected, it's important to identify which stage you're working with. The signs and symptoms of compensated and decompensated shock are different, and if shock is left untreated it can be lethal. For this reason, it is imperative that shock is treated as early as possible to avoid reaching the irreversible phase. Shock can occur in many emergency medical scenarios, including those with massive blood loss internal or external.

It can also occur when there are severe fractures, during a spinal, abdominal or chest injury, when a severe infection or major heart attack occurs, and during anaphylaxis. When shock is suspected or observed, taking frequent vital signs and assessing the mental state of the patient is the best way to monitor the progression of shock.

If responding to an emergency in which shock is suspected, a quick assessment of the patient should be completed to measure the level of consciousness, mental state and vital signs. For treating compensated shock, the initial step is going to be identifying the cause of shock and treating it.

Once that is done, measures to treat shock can be taken. During transport, this is typically applying high-flow oxygen and warming blankets to maintain a temperature in the normal range. Inadequate ventilation can be a major factor in the development and progression of shock. Continue to monitor vital signs and mental state every few minutes and note any changes. With compensated shock, the body is able to take measures to maintain blood pressure, however as shock worsens, the body becomes unable to keep up.

At this point, perfusion of vital organs is no longer maintained. With decompensated shock, it may be necessary to request advanced life support measures for the patient. Priority should be given to management of the airway and treatment of the underlying cause of shock. A decrease in blood pressure is often an indication of late-stage shock and treatment should start well before this is detected. If the condition remains untreated, it will progress into irreversible shock which ultimately leads to death of the patient.

The key toward successfully treating shock is a rapid response. If it can be treated before reaching the decompensated phase, that is best.

In many major life-threatening situations, the development of shock should be anticipated. This requires a speedy assessment of the patient and quick transport to a trauma facility.

In a child who is critically injured there is the potential for many serious or life-threatening injuries. The initial focus must always be to stabilize the child's airway and breathing and, then, rapidly identify shock and aggressively correct volume deficits. Failure to recognize and manage shock is a major cause of preventable deaths in pediatric trauma patients. Knowledge of the unique physiologic and anatomic features of children will allow the clinician to rapidly assess and effectively manage the pediatric trauma patient in shock.

This article will review the unique aspects of children, pediatric anatomic and physiologic differences that affect recognition of shock in children versus adults, and how these differences translate into patient management strategies. The care of a trauma patient must always proceed from assessing airway, breathing, and circulation to identification and delineation of all injuries and appropriate management.

Although pediatric patients are far more likely to suffer problems with inadequate ventilation than circulatory failure, 1 inappropriate resuscitation or unrecognized shock is a major cause of preventable death. A patient's vital signs must be considered in conjunction with age, as well as other factors.

Age variations in vital signs and weight, as well as the presence of fever, crying, or an inappropriately sized blood pressure cuff can all affect vital signs, complicating the picture, and making shock challenging to recognize. Care of the pediatric patient requires knowledge of appropriately sized equipment for any given age, as well as excellent ED organization of supplies, so that immediate access to equipment is ensured.

Injury mechanisms for children differ from those of adults. The term "unintentional injury" was coined as an alternative to "accident" to emphasize that these injuries can be prevented. Unintentional injury represents the leading cause of death in all children except those younger than 1 year 3 and accounts for more deaths than all other mechanisms combined. Childhood injury follows different patterns depending on age, sex, and developmental stage. In infants and toddlers, falls are a common cause of severe injury, while older children and adolescents experience severe injury from bicycle and motor vehicle accidents.

Within the category of "unintentional injury," motor vehicle traffic accidents accounted for Children aged 1 to 4 years had significant rates of death caused by drowning Homicide, often traumatic in nature, is the second cause of death in children and young adults aged 15 to 24 years.

Suicide is the third ranked cause of death in children and young adults aged 10 to 14 years and 15 to 24 years.A low blood pressure is not diagnostic, especially in children: given remarkable ability to compensate. Children who have been appropriately fluid resuscitated AND are refractory to vasopressor should be started on stress dose steroids for secondary adrenal insufficiency.

Target fluid resuscitation based on CVP indirect measure of preload. Signs: capillary refill, skin turgor, skin temperature, pulse characteristics, hyperdynamic precordium, urine output, altered level of consciousness, increased respiratory effort. If central line is in SVC, check venous saturation.

Based on exam and blood pressure initiate either norepinephrine, epinephrine, or milrinone see ACCM algorithm. After addressing ABCs move onto identifying source for infection and laboratory investigation.

Send blood work CBC, DIC, type and screen may need to optimize oxygen carrying capacity as pathophysiology evolvesCMP, magnesium, ionized calcium, glucose, phosphorus, lactate, UA, CRP, urine culture, blood culture, respiratory culture, endotracheal tube culture if intubated.

Pay attention particular attention to ionized calcium and glucose in first few minutes of assessing child. Infants higher likelihood of hypoglycemia. Chest radiograph. Additional imagining studies will depend on signs and symptoms i. CT of abdomen or head. O 2 content CAO 2 — [1. Too much load on the muscle fibers depresses function. SvO 2 commonly assumed to represent the mean tissue PO 2. Pulmonary arterial sample.

Considerations in the Management of Shock in the Pediatric Trauma Patient

It must be remembered that the SvO 2 measures oxygen saturation present in venous drainage of all tissues beds, thus is influenced by relative contributions from tissues with differing metabolic needs.

In carotid sinus, aortic arch. Decreased vagal tone, increased HR, decreased coronary resistance, improving myocardial oxygen supply. Progresses to increased sympathetic tone, increase in peripheral skin and muscle bed vasoconstriction, increasing circulating blood volume. Osmotic pressure becomes greater than hydrostatic pressure, reabsorption of fluids occurs in the capillary beds. Renal conservation of water by the release of aldosterone stimulated by vasopressin causes sodium reabsorption in the renal distal tubule and water follows.

Shock is a state the body can enter into as a response of either serious trauma or intense pain. Shock is a very real and deadly condition, and should not be treated lightly. Shock can often occur as a deadly side effect to an otherwise non-fatal injury, such as a broken leg.

Below are the most common symptoms of shock:. Shock is a very serious condition and needs to be addressed immediately. Shock can result in death, whether or not the injury that caused the shock was life threatening.

If you suspect your child is going into shock, call immediately. While you are waiting for emergency crews, you should Keep your child warm by covering them with a blanket. Normal respiratory rates in children and adults. This is the rate at which a person breathes. It increases with fever, illness, and shock. To determine the respiratory rate in your child, remove their shirt, and count the number of times the chest rises in 1 full minute.

Or do this for 15 seconds and multiply that number by 4 to get a rate per minute. Normal newborn respiration rate: breaths per minute Normal year old respiration rate: breaths per minute 7 years to adult respiration rate: breaths per minute Of course, respiratory rates will also increase with physical activity, so you have to factor this into your account.

Former Vegas bookmaker Micah Roberts previews Thursday's NFL Kickoff game and shares his top play on Chiefs-Patriots.

ETThe Patriots start their championship defense at home against the Chiefs on Thursday night in a spot where the spread has been rising following a trend from last season.

New England comes into the game with a key player out while Kansas City is starting a rookie running back. It's a battle between two of the most opportunistic defenses, but best of all it's the first NFL game of the year. Let's get this 2017 party started. LAS VEGAS ACTION"We opened the Patriots -7. Station Casinos have reached the highest in town at Pats -9. The Westgate SuperBook opened New England -7 with a total at 50 on April 20 when the NFL schedule was first announced and is now dealing -9.

ROBERTS' RATINGI've got the Patriots 4 points better than the Chiefs and I give the Patriots a full 3 points for home field, so it's an easy 7-point spread for me.

ADVANCED COMPUTER MODEL PICKS EVERY WEEK 1 GAMEUsually, I would jump on an opportunity like this where there's over 20 percent of perceived value at the books compared with my number, but the Patriots are a different story.

Their 2016-17 season was incredible, as they went 15-3-1 ATS against inflated spreads.

What AGT didn't tell you about Archie Williams - America's Got Talent 2020

GREATNESS DEFINEDTom Brady and Bill Belichick won their fifth Super Bowl together last season in what was their sixth consecutive year of making the AFC Championship game.

They've had at least 12 wins for the past seven regular seasons. They've made the playoffs in 13 of their past 14 seasons. They've become an expectant dominator, but I don't think they get the full credit they deserve. This is the greatest dynasty in the NFL. And last year's run against-the-spread where they killed the sports books weekly was new territory for me -- it's when I realized just how good they are.

If you can beat Las Vegas weekly when the spreads keep getting inflated along the way, that's impressive. Las Vegas normally doesn't lose in those situations, but the Patriots did it like no other team.
