Understanding Infant Colic

Colic in Infants

• Colic is a distressing condition in infants, marked by intense crying, usually in the late afternoon or evening.
• Commonly manifests within the first few weeks of life, causing stress and anxiety for caregivers.
• Exact causes are unclear; believed to stem from gastrointestinal discomfort, immature nervous systems, or environmental influences.

Definition and Characteristics

• Defined by Wessel et al.: crying for more than three hours a day, three days a week, lasting for three weeks.
• Excessive, paroxysmal crying typically occurs in otherwise healthy infants aged 2 weeks to 4 months, often unidentifiable in cause.
• Equally likely in breastfed and formula-fed infants.

Pathophysiology

• The term "colic" is derived from the Greek word "kolikos," indicating a possible disturbance in the gastrointestinal tract.

Management Strategies

• Encourage caregivers to take breaks to avoid exhaustion.
• Consistent follow-up support from a sympathetic physician is crucial for managing colic.
• Dicyclomine hydrochloride has shown efficacy but may cause serious side effects; not widely recommended.

Dietary Considerations

• Maternal low-allergen diets (excluding dairy, soy, eggs, peanuts, wheat, and shellfish) might alleviate excessive crying in some infants.

Pharmacologic Management

• Simethicone aids gas expulsion by altering surface tension of gas bubbles.
• Herbal remedies like chamomilla, bitter apple, and fenugreek have cultural significance, but their safety and efficacy require further research.

Nursing Care

• Address acute pain from abdominal distention; provide comfort measures and rest.
• Educate caregivers about colic and effective coping strategies.
• Enhance parenting skills by identifying concerns, offering education on child development, and encouraging positive parenting practices.

Goals of Nursing Care

• Aim to reduce and relieve pain through immediate acknowledgment and comfort positioning.
• Assess caregiver’s ability and readiness to learn; create a tailored education plan in a peaceful environment.
• Foster parental engagement in caregiving activities to build confidence.

Evaluation of Care

• Monitor achievement of care goals via:
  • Individual behavioral assessments and interactions.
  • Documentation of intake and output.
  • Consideration of cultural beliefs influencing care plans.
  • Reviewing responses to interventions and teaching effectiveness.

Dengue Hemorrhagic Fever (DHF) Overview

• Severe form of dengue fever that can be fatal, marked by bleeding and hypovolemic shock.
• Caused by one of the four serotypes of the dengue virus, a member of the Flavivirus genus.
• Transmitted primarily by Aedes mosquitoes, especially Aedes aegypti, which breed in stagnant water.
• Also known as Breakbone Fever, Hemorrhagic Fever, Dandy Fever, and Infectious Thrombocytopenic Purpura.

Pathophysiology

• Initial phase resembles typical dengue fever; viremia occurs within days of mosquito bite.
• Symptoms appear around the fifth day after infection.
• Hemorrhagic symptoms and plasma leakage develop shortly after fever subsides.
• Vascular leakage may result in hemoconcentration, serous effusions, and circulatory collapse.
• Untreated DHF can progress to dengue shock syndrome.

Statistics and Incidence

• Reportable disease in the U.S.; suspected cases must be reported to public health authorities.
• 2.5 to 3 billion people in approximately 112 countries experience dengue transmission.
• Annually, 50-100 million infections occur globally.
• Mortality rate for dengue fever is less than 1%.
• Mortality for DHF is 2-5% with treatment, rising to 50% if untreated.
• Dengue fever affects all ages but is more common in children.

Causes

• Etiological agent is the dengue virus, classified as a Flavivirus, identifiable by its nonsegmented RNA structure.
• Aedes aegypti is the primary mosquito vector, identifiable by white dots on wings and bands on legs.
• Incubation period ranges from three to ten days post-exposure.

Clinical Manifestations

• Symptoms appear 4-6 days post-infection and may last up to 10 days.
• Diagnostic methods include:
  • Blood tests for dengue virus isolation from serum, plasma, or leukocytes.
  • Immunoglobulin titer changes in paired serum samples.
  • Immunohistochemistry or immunofluorescence to identify virus antigen in tissues.
  • Polymerase chain reaction (PCR) to detect viral genomic sequences.
  • Complete blood count showing increased hematocrit and decreased platelet count.
  • Guaiac test for occult blood in stool for suspected cases.

Medical Management

• Early detection is crucial for effective management.
• Oral rehydration therapy indicated for moderate dehydration.
• Intravenous fluids necessary for severe dehydration.
• Blood transfusions may be required in cases of hemorrhage or coagulopathy.
• Patients advised to avoid aspirin and NSAIDs due to increased hemorrhage risk.

Nursing Management

• Essential for patient recovery, requiring careful monitoring and supportive care.
