TCA Overdose (Tricyclics)

9/2/2023

0 Comments

TCA Overdose

Tricyclic antidepressants (TCAs) are a class of drugs used to treat depression, chronic pain, and other neuropsychiatric disorders.
TCA overdose can lead to severe toxicity and even death.
In this lecture, we will discuss the clinical and ECG features of TCA overdose, as well as its management.

Clinical Features of TCA Overdose

Symptoms and signs of TCA overdose usually occur within 1-2 hours, which include:

Sedation and coma
Seizures
Hypotension
Tachycardia
Wide complex dysrhythmias
Anticholinergic syndrome (tachycardia, mydriasis, dry mouth)

TCAs are rapidly absorbed in the gastrointestinal tract.
Toxic effects are produced by blockade at muscarinic (M1), histamine (H1), and α1-adrenergic receptors.

ECG Features of TCA Overdose

An ECG is a vital tool in the prompt diagnosis of poisoning with sodium-channel blocking medications such as TCA, which cause CNS and cardiovascular toxicity in overdose in the form of seizures and ventricular dysrhythmias.
The most common ECG features of TCA overdose include:

Intraventricular conduction delay: QRS > 100 ms in lead II
Terminal R wave > 3 mm in aVR or R/S ratio > 0.7 in aVR
Sinus tachycardia secondary to muscarinic (M1) receptor blockade
Terminal right axis deviation of the QRS complex, which manifests as a dominant R’ wave in aVR due to the right-sided intraventricular conducting system being more susceptible to the effects of sodium channel blockade.

The degree of QRS widening on ECG is correlated with adverse events:

QRS > 100 ms is predictive of seizures.
QRS > 160 ms is predictive of ventricular arrhythmias (e.g. VT).

Management of Tricyclic Overdose
Overdose >10mg/kg with signs of cardiotoxicity (ECG changes) requires resuscitative management:

Patients need to be managed in a monitored area equipped for airway management.
Secure IV access, administer oxygen, and attach monitoring equipment.
Administer IV sodium bicarbonate.
Intubate as soon as possible and hyperventilate to maintain a pH of 7.50 to 7.55.
Once the airway is secure, place a nasogastric tube and give 50g (1g/kg) of activated charcoal
Treat seizures with IV benzodiazepines (e.g. midazolam 1-2mg)
Treat hypotension with a crystalloid bolus (10-20 mL/kg). If this is unsuccessful in restoring BP then consider starting vasopressors (e.g. noradrenaline infusion)
If arrhythmias occur, the first step is to give more sodium bicarbonate. Lidocaine (1.5mg/kg) IV is a third-line agent (after bicarbonate and hyperventilation) once pH is > 7.5
Avoid Ia (procainamide) and Ic (flecainide) antiarrhythmics, beta-blockers, and amiodarone as they may worsen hypotension and conduction abnormalities
Admit the patient to the intensive care unit for ongoing management

Take home message:

TCA overdose can lead to severe toxicity and even death.
The best markers for suspected overdose are a history of depression, suicidality, and overdose with a sudden deterioration in mental status and vital signs.
Clinical features of TCA overdose include sedation, seizures, hypotension, tachycardia, wide complex dysrhythmias, and anticholinergic syndrome.
An ECG is a vital tool in the prompt diagnosis of TCA overdose.

Management of significant TCA overdose requires resuscitative management, including IV sodium bicarbonate, intubation and hyperventilation, and treatment of seizures and hypotension.

Measles

Measles is a highly contagious disease caused by a virus. It spreads easily when an infected person breathes, coughs, or sneezes, potentially leading to severe complications and even death. While anyone can be affected, children are the most common victims of this disease.

Symptoms

The measles virus infects the respiratory tract and swiftly spreads throughout the body. Its symptoms include a high fever, cough, runny nose, Koplik spots in the mouth, and a maculopapular rash covering the entire body.
Koplik's spots seen inside the mouth are diagnostic for measles, but are temporary and therefore rarely seen. Koplik spots are small white spots that are commonly seen on the inside of the cheeks opposite the molars. They appear as "grains of salt on a reddish background."
The measles rash is a generalized red maculopapular rash that begins several days after the fever starts. It starts on the back of the ears and spreads to the head and neck before spreading to cover most of the body, often causing itching. The measles rash appears two to four days after the initial symptoms and lasts for up to eight days. The rash is said to "stain", changing color from red to dark brown, before disappearing. Overall, measles usually resolves after about three weeks.

Vulnerability

Complications tend to be most common in children under 5 and adults over 30. Those who are malnourished or have weakened immune systems, especially due to conditions like HIV, are at higher risk. Measles itself weakens the immune system, leaving children exceptionally vulnerable.

Transmission

Measles is one of the most contagious diseases that spreads through air and contact with infected secretions. The virus remains active on surfaces for up to two hours, making it highly infectious. Vaccination remains the most effective way to prevent its spread.

Treatment

Currently, there's no targeted treatment for measles. Treatments are supportive and focus on managing symptoms and preventing complications. Adequate hydration, a balanced diet, and antibiotics for complications such as pneumonia or ear infections are vital. Vitamin A supplements are essential to prevent complications and deaths.

Vaccination

Community-wide vaccination is pivotal in preventing measles. The vaccine is safe, effective, and affordable. Children require two doses for full immunity, and routine vaccination, coupled with mass campaigns, plays a crucial role in decreasing global measles deaths.

The "Identify-Isolate-Inform" tool

This tool is designed to help clinicians detect and manage measles patients presenting to the emergency department

1. Identify.

Recognize the signs and symptoms of measles. Clinicians should also inquire about immunization status, sick contacts, and travel to a region with measles.

2. Isolate.

Take appropriate infection control measures to prevent the spread of measles to other patients and healthcare workers. This may include placing the patient in a private room and using personal protective equipment. Isolated patients should have samples obtained urgently and sent to the local public health department laboratory for disease confirmation.

3. Inform.

Notify the local health department and the hospital's infection control. This allows for proper public health measures to be implemented, such as contact tracing and vaccination campaigns.

Summary

In summary, this lecture encourages clinicians to stay informed about measles and emphasizes the importance of quick diagnosis to prevent the spread of the disease in your community. One should stay up-to-date on clinical features and diagnosis of measles or other communicable diseases by attending orientation sessions and reviewing resources from trusted sources like CDC.

How to troubleshoot a ventilator alarm
As a healthcare provider, it is crucial to be able to troubleshoot a ventilator alarm quickly and efficiently. One helpful tool for remembering the potential causes of an alarm is the "DOPES" mnemonic. Here's what it stands for:

Dislodged/displaced ETT : The endotracheal tube (ETT) may become dislodged or displaced, leading to an alarm. Check the placement of the ETT to ensure it is in the correct position.
Obstructed ETT (mucus, blood, kink): An obstruction in the ETT can cause an alarm. Check for any mucus or blood in the tube, and ensure that it is not kinked or blocked in any way.
Pneumothorax: A pneumothorax, or collapsed lung, can cause an alarm. Check for any signs of decreased breath sounds or chest asymmetry.
Equipment failure (disconnect and try BVM): Sometimes, the ventilator itself may be the cause of the alarm. If this is suspected, disconnect the patient from the ventilator and try bag-valve-mask (BVM) ventilation instead.
Stacked breathing (auto-PEEP): Stacked breathing, or auto-positive end-expiratory pressure (auto-PEEP), can cause an alarm. This occurs when the patient is not exhaling completely before the next breath is delivered. Check for signs of increased work of breathing or decreased tidal volume.

Remembering the "DOPES" mnemonic can help healthcare providers troubleshoot a ventilator alarm quickly and effectively. By checking for these potential causes, providers can ensure that their patients receive the appropriate care and treatment.

Ecthyma gangrenosum

Ecthyma gangrenosum is a rare but serious cutaneous infection that is most commonly associated with Pseudomonas aeruginosa bacteremia. It usually occurs in patients who are critically ill and immunocompromised.
The lesions of ecthyma gangrenosum begin as painless, round erythematous macules and patches that develop into central pustules with surrounding erythema. A hemorrhagic vesicle appears at the center of the lesion and evolves into a gangrenous ulcer with a black eschar. Early lesions may progress to necrotic ulcers in as little as 12 hours. The lesions can be localized and solitary, or widespread.
Impaired humoral or cellular immunity leads to increased susceptibility to infections with Pseudomonas aeruginosa or other pathogens. In addition, breakdown of mechanical defensive barriers, such as the skin and mucosa, may allow infectious organisms to disseminate. The lesions of ecthyma gangrenosum result from perivascular bacterial invasion of arteries and veins in the dermis and subcutaneous tissues, producing a necrotizing vasculitis.
Ecthyma gangrenosum is typically and most commonly caused by Pseudomonas aeruginosa, but other bacteria, including Proteus species, Escherichia coli, and methicillin-resistant Staphylococcus epidermidis, have been implicated in similar lesions. A skin biopsy is taken for routine histology and special stains may also be done to rule out other organisms that may cause ecthyma gangrenosum-like lesions. Treatment of ecthyma gangrenosum involves prompt and aggressive antibiotic therapy, as well as supportive care.

Superior Vena Cava Syndrome

Superior vena cava (SVC) syndrome is a condition caused by the obstruction of the superior vena cava. SVC plays a vital role in facilitating blood flow from the upper body to the heart.
The hallmark symptoms of SVC syndrome include facial swelling and shortness of breath. Facial swelling can serve as an early indicator of SVC syndrome. Shortness of breath results from compromised blood flow and requires immediate attention. Venous distention, manifested through swelling of the neck and upper chest, provides diagnostic clues. Headaches and lightheadedness are also common. Symptoms of SVC syndrome usually evolve over time gradually.
Malignant tumors, such as lung cancer (most commonly small cell carcinoma) and non-Hodgkin's lymphoma (most commonly diffuse large B-cell lymphoma), are the primary causes of SVC syndrome. These tumors can compress the superior vena cava, leading to obstruction. Non-malignant causes of SVC syndrome are often due to the increased use of intravascular devices. Thrombosis resulting from these devices can lead to obstruction. Uncommonly, infectious diseases like syphilis and tuberculosis can cause SVC syndrome.
Pemberton's sign, also known as Pemberton's maneuver, is a clinical test used to assess for SVC syndrome. During the test, the patient raises both arms above their head for one minute. If this maneuver leads to facial flushing, bluish skin discoloration, or difficulty breathing, it may indicate obstruction of the superior vena cava.
Chest X-rays are used as a foundational tool in the initial assessment of SVC syndrome. They provide insights into mediastinal widening and potential causes. Some patients with SVC syndrome may present with normal chest X-rays, posing a diagnostic challenge. A comprehensive understanding of the syndrome's presentation is necessary to overcome this challenge. CT scans play a vital role in diagnosing SVC syndrome, complementing chest X-rays. Enhanced with contrast, these scans provide a comprehensive view of the affected areas and reveal the extent of disease progression. Advanced diagnostic approaches, such as transbronchial needle aspiration and mediastinoscopy, offer valuable insights into the underlying causes of SVC syndrome.
The treatment of SVC syndrome includes drug therapy and surgical interventions tailored to address the underlying causes and relieve symptoms. Glucocorticoids, such as prednisone and methylprednisolone, reduce the inflammatory response associated with SVC syndrome. Their efficacy depends on the tumor's responsiveness to steroid treatment. Diuretics, such as furosemide, alleviate pressure by reducing venous return to the heart. In select cases, endovascular stenting provides swift resolution to SVC syndrome symptoms. This interventional procedure has minimal associated risks. Endovascular stenting involves inserting a small, flexible tube stent into the obstructed area of the superior vena cava. The stent helps to widen the vein and restore blood flow. Radiation therapy plays a vital role in providing symptomatic relief for SVC syndrome patients. It alleviates symptoms and improves patients' quality of life.
In cases of SVC syndrome, it is generally advisable to avoid administering intravenous (IV) fluids or medications through the upper limbs (arms) whenever possible. This is because the obstruction in the SVC can impede blood flow from the upper body back to the heart. If IV fluids are administered through the upper limbs, it could exacerbate the swelling and pressure in the veins, potentially leading to further complications.

Summary

In conclusion, the symptoms of SVC syndrome are usually relieved with radiation therapy within one month of treatment. However, even with treatment, the prognosis for SVC syndrome is poor. Most patients die within two and a half years. This relates to the cancerous causes of SVC.

The treatment options for shock

The treatment options for shock depend on the type of shock and the underlying cause. Here are some of the common treatment options for shock:
Crystalloid resuscitation restores intravascular volume and improves blood pressure in hypovolemic or septic patients.
Point-of-care ultrasound (Po-Cus) is a diagnostic tool that can help identify the underlying cause of shock, such as obstructive shock.
In cases of hemorrhagic shock, blood products such as packed red blood cells may be administered to replace lost blood volume.
Norepinephrine is a vasopressor medication that can be used to constrict blood vessels and increase blood pressure. Dobutamine is an inotropic medication that can increase cardiac output.
Vasopressin is another vasopressor medication that can be used to increase blood pressure.
Epinephrine is a medication that can be used to treat anaphylaxis, asthma, or atrioventricular block.
Methylene blue is a medication that can be used to treat distributive shock caused by nitric oxide overproduction.
High-dose insulin euglycemic therapy, HIET, is a treatment strategy that involves administering high doses of insulin to improve myocardial contraction, especially in cases of overdose from beta-blockers or calcium channel blockers.
Extracorporeal life support, ECLS, is a life support technique that can be used in cases of refractory shock to provide temporary support for the heart and lungs.

Summary

The specific treatment approach for shock depends on the underlying cause and severity of the condition.

Types of Shock

Shock is a critical medical condition which consists of a range of categories, each with distinct triggers, manifestations, and therapeutic implications. The 5 types of shock are hypovolemic shock, cardiogenic shock, distributive shock, septic shock, and obstructive shock. Distributive shock includes anaphylactic shock, neurogenic shock, and the early stage of septic shock (warm shock).

1. Hypovolemic Shock:

Hypovolemic shock occurs when there is a significant loss of blood and body fluids, often due to trauma or injury. For example, a severe car accident resulting in massive internal bleeding can trigger this type of shock. When a person loses approximately one-fifth or more of their blood volume, the heart has difficulty pumping enough blood to vital organs. This deficiency in oxygen-rich blood circulation can cause organ dysfunction and even failure.
The early signs of hypovolemic shock include low blood pressure, rapid heart rate, and pale, cool skin.
Immediate fluid replacement through intravenous (IV) fluids is a cornerstone of treatment.

2. Cardiogenic Shock:

Cardiogenic shock is a life-threatening condition that occurs when the heart cannot pump enough blood to meet the body's needs. For example, the heart's muscles can be severely damaged during a heart attack, impeding its pumping efficiency. Additionally, conditions like severe heart failure can also contribute to cardiogenic shock.

ECG and cardiac biomarker levels are two important tools for diagnosis of cardiogenic shock.
Treatment for cardiogenic shock is aimed at improving the heart's pumping ability and restoring blood flow to the body. Medications include inotropic agents, such as dobutamine and epinephrine, and vasopressors, such as norepinephrine. Coronary angioplasty and stenting may be used to open blocked arteries.

3. Distributive shock

Distributive shock, also known as vasodilatory shock, is characterized by the impaired distribution of blood flow and excessive vasodilation.
In this type of shock, the body is unable to get enough blood to the heart, brain, and kidneys, leading to inadequate tissue perfusion.
Examples of distributive shock include anaphylactic shock, neurogenic shock, and the early stage of septic shock.

3-1. Anaphylactic Shock:

Anaphylactic shock is a life-threatening systemic allergic reaction, triggered by substances like foods, insect stings, or medications. For instance, a peanut-allergic individual consuming even trace amounts of peanuts can experience anaphylactic shock.
Symptoms of anaphylactic shock include hives, swelling, abdominal pain, difficulty breathing, airway constriction (bronchospasm), angioedema, and severe hypotension.

Anaphylactic shock is a medical emergency and requires prompt treatment. The first-line treatment of anaphylactic shock is intramuscular epinephrine, 0.3 to 0.5 mg in adults; 0.01 mg/kg in children (maximum: 0.3 mg).
Educate patients with known allergies about carrying an epinephrine auto-injector and avoiding allergens.

3-2. Neurogenic Shock:

Neurogenic shock occurs in patients with spinal cord injury above the T6 level.
The disruption in autonomic nervous system control results in widespread vasodilation, relative bradycardia, and hypotension.

In patients with suspected spinal cord injury, immobilize and stabilize the spine to prevent further damage during initial assessment and management.
Intravenous fluids and vasopressors, such as dopamine and norepinephrine, may be necessary to restore and maintain blood pressure and heart rate.

4. Septic Shock:

Septic shock results from widespread infection, usually due to bacteria, leading to a systemic inflammatory response. It primarily affects vulnerable populations such as infants, the elderly, and those with compromised immune systems. For instance, a severe urinary tract infection can progress to sepsis and subsequently to septic shock.
The early stage of septic shock, also known as warm or hyperdynamic shock, is a type of distributive shock, in which the pulse pressure is widened due to vasodilation.

Signs of sepsis include fever, chills, hypothermia, confusion, hyperventilation, warm skin in the early stage, and clammy skin in the late stage.
Early recognition and management of sepsis may prevent progression to septic shock.
Swift administration of broad-spectrum antibiotics is pivotal while awaiting culture results.
Identify the source of infection and treat it with surgery if indicated.
Monitor patients closely for signs of multi-organ dysfunction, as septic shock can lead to organ failure.

5. Obstructive shock

Obstructive shock is characterized by a significant reduction in blood flow to the body's tissues and organs due to obstruction of blood flow within the circulatory system. This obstruction can occur within the heart, major blood vessels, or other structures that affect the heart's ability to pump blood.
Examples of obstructive shock include: pulmonary embolism, cardiac tamponade, tension pneumothorax, vena cava compression syndrome, and mediastinal tumors.
The definitive treatment of obstructive shock depends on the underlying cause and may include surgical drainage or pericardiocentesis to remove pericardial fluid or air, removal of an embolism with surgery or a catheter, or replacing a severely narrowed aortic valve.

Take Home Message

In conclusion, understanding the different types of shocks is crucial for healthcare professionals to provide timely and effective interventions. Recognizing the underlying triggers, clinical presentations, and appropriate management strategies ensures optimal patient outcomes.

Treatment of Acute Lung Edema: The POND Mnemonic

Acute lung edema is a condition where fluid accumulates in the lungs, making it difficult to breathe. The POND mnemonic is a useful tool for remembering the key treatments for acute lung edema.

P: Position / PPV

The first step in treating acute lung edema is to position the patient upright or in a semi-upright position. This helps to reduce the amount of fluid in the lungs and improve breathing. Positive pressure ventilation (PPV) may also be used to help improve oxygenation in patients who are struggling to breathe.

O: Oxygen

High-flow oxygen should be administered initially to improve oxygenation. Oxygen saturation should be monitored and titrated to keep it between 92-96%. If oxygen saturation cannot be maintained within this range, CPAP or BiPAP may be used in a critical care unit or high dependency unit.

N: Nitroglycerin

Nitroglycerin is a vasodilator that can help to reduce the workload on the heart and improve blood flow. Use nitroglycerin sublingual followed by infusion. High-dose nitroglycerin can be used to treat sympathetic crashing acute pulmonary edema (SCAPE) with SBP >160 mm Hg, but it should be used with caution in patients with low blood pressure or other contraindications. High dose NTG is 600-1000 mcg IV bolus followed by 100 mcg/min infusion, titrate as needed.
Contraindications to NTG use include severe aortic stenosis, recent use of phosphodiesterase type 5 inhibitors (e.g. sildenafil, tadalafil, vardenafil), hypertrophic obstructive cardiomyopathy, or hypotension at any time.

D: Diuretics

Diuretics are medications that help to remove excess fluid from the body. They are a key treatment for acute lung edema. Furosemide is the most commonly used diuretic in this setting. The recommended dose is 40-80 mg IV bolus, with additional doses given as needed.

Take Home Message

In summary, the POND mnemonic is a useful tool for remembering the key treatments for acute lung edema. Positioning the patient upright, administering high-flow oxygen, using high-dose nitroglycerin, and administering diuretics are all important steps in managing this condition. However, it is important to remember that treatment should be tailored to the individual patient, and that other treatments may be necessary depending on the severity of the condition and the underlying cause.

Pitfalls in the Diagnosis and Management of Aortic Dissection
Aortic dissection, a grave medical emergency, demands swift and accurate diagnosis and treatment. However, a multitude of potential pitfalls exist that can derail effective management or lead to misdiagnosis. Here are some common pitfalls to be aware of when encountering aortic dissection:

Failure to consider aortic dissection: Aortic dissection can present with a wide range of symptoms, including chest pain, back pain, abdominal pain, stroke, and other neurological deficits such as syncope. It is important to have a high index of suspicion for aortic dissection, especially in patients with risk factors such as hypertension, connective tissue disorders, or a family history of aortic disease.
Misdiagnosis as other conditions: Aortic dissection can mimic other conditions such as myocardial infarction, pulmonary embolism, and musculoskeletal pain. It is crucial to differentiate aortic dissection from these conditions, as the management and prognosis can be significantly different.
Reliance on clinical findings alone: Clinical findings alone are not sufficient to diagnose aortic dissection. A thorough physical examination is important, including blood pressure measurement in both arms and auscultation for aortic regurgitation. Imaging studies, such as computed tomography angiography (CTA) or transesophageal echocardiography (TEE), are necessary to confirm the diagnosis.
Delay in obtaining imaging studies: Aortic dissection is a time-sensitive condition, and delays in obtaining imaging studies can lead to delays in diagnosis and treatment. If aortic dissection is suspected, imaging studies such as CTA and TEE should be obtained promptly.
Misinterpretation of imaging studies: Interpreting imaging studies for aortic dissection can be challenging, especially in cases of atypical presentations or subtle findings. It is important to have expertise in interpreting these studies or to consult with a specialist if there is uncertainty.
Inadequate blood pressure control: Blood pressure control is crucial in the management of aortic dissection. Hypertension can worsen the dissection and increase the risk of complications. It is important to initiate antihypertensive therapy promptly and titrate to target blood pressure levels. Recommended antihypertensive medications include: beta-blockers, such as metoprolol or labetalol, calcium channel blockers, such as diltiazem or verapamil, and nitroprusside.
Failure to consider surgical intervention: Surgical intervention is often necessary in cases of aortic dissection, especially in those with complications such as aortic rupture or malperfusion. It is important to involve a cardiovascular surgeon early in the management of aortic dissection to determine the need for surgical intervention.
Inadequate pain management: Aortic dissection can cause severe pain, and inadequate pain management can lead to increased sympathetic activity and aortic wall stress, resulting in increased morbidity and mortality. It is important to provide adequate pain relief, often with intravenous opioids, while monitoring for potential adverse effects.
Lack of multidisciplinary approach: Aortic dissection requires coordination of care among multiple specialties, including cardiologists, cardiovascular surgeons, radiologists, and other specialists. Collaboration among these specialties is crucial for optimal management and outcomes.
Failure to address long-term management: Aortic dissection is a chronic condition that requires long-term management to prevent complications such as recurrent dissection or aneurysm formation. Regular follow-up imaging studies and blood pressure control are essential in the long-term management of aortic dissection.
Lack of patient education: Patients with aortic dissection require education about their condition, including the importance of blood pressure control, the need for regular follow-up imaging studies, and the signs and symptoms of complications. Inadequate patient education can lead to poor adherence to treatment and increased risk of complications.
Failure to address underlying risk factors: Aortic dissection is often associated with underlying risk factors such as hypertension, connective tissue disorders, or atherosclerosis. It is important to address these risk factors to prevent recurrent dissection or other cardiovascular events. Lifestyle modifications, such as regular exercise, a healthy diet, and smoking cessation, should be encouraged. Medications to control hypertension and lipid levels may also be prescribed.
Inadequate communication with the patient: Aortic dissection can be a frightening and overwhelming diagnosis for patients and their families. It is important to communicate clearly and compassionately with the patient and involve them in the decision-making process. Provide information about the condition, treatment options, and potential complications in a way that the patient can understand.
Lack of awareness of emerging therapies: Emerging therapies such as thoracic endovascular aortic repair (TEVAR) or hybrid procedures may be appropriate in select cases of aortic dissection. It is important to stay up-to-date on these emerging therapies and refer patients to centers with expertise in these procedures when appropriate.
Inadequate monitoring of vital signs: Vital signs such as blood pressure, heart rate, and oxygen saturation should be closely monitored in patients with aortic dissection. Sudden changes in these parameters can indicate worsening of the dissection or the development of complications.
Inadequate evaluation and management of complications: Complications such as aortic rupture, malperfusion, or stroke can occur in patients with aortic dissection. It is important to manage these complications promptly and appropriately to prevent further morbidity and mortality.

In conclusion, aortic dissection is a complex and potentially life-threatening condition that requires a high index of suspicion, prompt diagnosis, and multidisciplinary management. By being aware of the potential pitfalls in the diagnosis and management of aortic dissection, healthcare providers can improve patient outcomes and reduce the risk of complications.
