Obsolete Cold Injury Syndrome of Newborn: A Historical Perspective

Cold injury syndrome of newborn, also known as cold stress or hypothermia, was a condition that affected newborn infants exposed to cold temperatures. This disorder was characterized by a range of symptoms, including:

• Erythema: Redness and inflammation of the skin [9]
• Pallor: Pale or washed-out complexion
• Edema: Swelling due to fluid accumulation in tissues
• Scleredema: A condition marked by thickening of the skin

In severe cases, cold injury syndrome could lead to more serious complications, such as:

• Frostnip: Numbness and tingling sensations in extremities
• Frostbite: Permanent damage to skin and underlying tissues due to prolonged exposure to cold temperatures
• Gangrene: Death of tissue due to lack of blood supply

The condition was often associated with pre-term infants, who were more susceptible to temperature fluctuations [3][4]. However, it could also affect full-term newborns exposed to extreme cold.

Prevention and Treatment

Prevention involved identifying high-risk infants and providing them with proper care and attention. In cases where the condition did occur, intensive care was often necessary to prevent further complications [15].

It's worth noting that the term "cold injury syndrome of newborn" is now considered obsolete, as modern medical practices have improved significantly in preventing and treating hypothermia in newborns.

[3] Mann (1953) - First used the term "cold injury syndrome" to describe the condition observed in pre-term, newborn infants exposed to cold. [4] Mann and Elliot (1955-1957), Smallpiece and Jones (1955-1957) - Further research on the condition was conducted during this period. [9] Derratologic presentations of cold injury syndrome included erythema, pallor, edema, and scleredema.

Early Signs and Symptoms

Cold injury syndrome, also known as neonatal hard edema, can manifest in various ways. According to medical guidelines [1], early signs and symptoms may include:

• Poor weight gain or weight loss: Infants with cold injury syndrome may experience a decline in weight due to inadequate nutrition and energy expenditure.
• Excessive sweating (hyperhidrosis): Newborns with cold stress may exhibit excessive sweating, which can be an indicator of their body's attempt to regulate its temperature [2].
• Sleepiness and jitteriness: Infants with subtle signs of cold injury syndrome may appear sleepy or irritable, which can be a sign of their body's response to the condition [3].

Chronic Signs

If left untreated, cold injury syndrome can lead to more severe chronic signs, including:

• Neonatal hard edema: A condition characterized by swelling and discoloration of the skin, often accompanied by pain and discomfort.
• Respiratory distress: Infants with cold injury syndrome may experience respiratory difficulties, such as tachypnea (rapid breathing), nasal flaring, and chest wall retractions [4].

Other Complications

Untreated cold injury syndrome can lead to further complications, including:

• Tissue necrosis: In severe cases, cold injury syndrome can cause tissue death due to inadequate blood flow.
• Complex regional pain syndrome (CRPS): Some infants with cold injury syndrome may develop CRPS, a condition characterized by chronic pain and inflammation in the affected area [5].

It is essential to seek medical attention immediately if you suspect your newborn has cold injury syndrome. Early detection and treatment can significantly improve their chances of recovery.

Diagnostic Tests for Cold Injury Syndrome of Newborn

Cold injury syndrome, also known as neonatal cold injury or hard edema, is a condition that affects newborns due to exposure to cold temperatures. The diagnostic tests for this condition are crucial in identifying the affected infants and providing timely treatment.

• Low-reading thermometer: A low-reading thermometer is essential in diagnosing cold injury syndrome of newborn. This device helps measure the baby's temperature accurately, which is critical in determining the presence or absence of the condition [5].
• Chest X-rays: Chest X-rays are another diagnostic tool used to identify cold injury syndrome of newborn. These tests help detect any abnormalities in the lungs and other organs that may be affected by the condition [13].
• Blood tests: Blood tests, including complete blood count and coagulation tests, are also used to diagnose cold injury syndrome of newborn [12].
• Peripheral smear: A peripheral smear is a diagnostic test that examines the baby's blood cells. This test helps identify any abnormalities in the blood cells that may be related to the condition [12].

Other Diagnostic Criteria

In addition to these diagnostic tests, other criteria are used to diagnose cold injury syndrome of newborn. These include:

• Temperature lower than 35°C: A temperature lower than 35°C is a key indicator of cold injury syndrome of newborn [14].
• Symptoms such as placid, poor nursing, good color, and cool skin: Infants with cold injury syndrome may exhibit symptoms such as being placid, having poor nursing, maintaining good color, and having cool skin [14].

It's essential to note that a diagnosis of cold injury syndrome of newborn requires a comprehensive evaluation of the baby's overall health, including their temperature, respiratory status, hydration status, and other vital signs.

Treatment of Neonatal Cold Injury Syndrome

Neonatal cold injury syndrome, also known as hypothermia overshoot or cold-injury syndrome, is a condition that can occur in newborn infants when they are exposed to cold temperatures. The treatment for this condition focuses on rewarming the infant and managing any potential complications.

• Rewarming: The primary treatment for neonatal cold injury syndrome is rewarming the infant using an incubator or radiant warmer [10]. This helps to restore normal body temperature and prevent further complications.
• Monitoring and Treatment of Complications: Infants with neonatal cold injury syndrome may require monitoring and treatment for potential complications such as hypoglycemia, hypoxemia, and increased blood viscosity [6][8].
• Neonatal Encephalopathy: In some cases, neonatal encephalopathy (NE) can occur in infants who have experienced hypothermia. Therapeutic hypothermia is the only known treatment for NE, and it involves cooling the infant's body temperature to a certain level [9].

Medications Used

While there are no specific medications used to treat neonatal cold injury syndrome directly, some medications may be used to manage related complications or conditions.

• Ibuprofen: Ibuprofen is sometimes used to manage pain and inflammation in infants with hypothermia [12].
• Morphine: Morphine may be used to manage pain in infants who have experienced hypothermia [12].

Important Note

It's essential to note that the treatment for neonatal cold injury syndrome should only be administered by a qualified healthcare professional, such as a pediatrician or neonatologist. Any attempts to treat this condition without proper medical supervision can lead to further complications and harm.

Differential Diagnosis of Obsolete Cold Injury Syndrome of Newborn

The differential diagnosis of obsolete cold injury syndrome of newborn (CISS) involves considering various conditions that may present with similar symptoms to CISS. Some of these conditions include:

• Immersion foot syndromes: These are a group of disorders caused by exposure to cold water, which can lead to tissue damage and necrosis. Immersion foot syndromes can be classified into two main types: non-freezing cold injury (NFCI) and warm water-related injuries [2].
• Frostbite: This is a condition caused by exposure to temperatures at least several degrees below freezing, especially in cold air. Frostbite can cause damage to the skin and underlying tissues, leading to pain, numbness, and discoloration [6].
• Respiratory Distress Syndrome (RDS): This is a condition that affects newborns, characterized by difficulty breathing due to inadequate pulmonary surfactant. RDS can present with symptoms such as tachypnea, nasal flaring, chest wall retractions, expiratory grunting, central cyanosis, and apnea [7].
• Accidental hypothermia: This is a condition caused by exposure to cold temperatures, which can lead to a drop in body temperature below 95°F (35°C). Accidental hypothermia can be classified into four stages: mild, moderate, severe, or profound [15].

It's worth noting that CISS is an obsolete term and has been replaced by more specific and accurate diagnoses. The differential diagnosis of cold-related conditions should take into account the individual symptoms and presentation of each case.
