Nursing Clinical Practice for Dengue Hemorrhagic Fever: Summary of Symptoms, Observation, Care, Treatment, and Precautions (For Nursing Students)
Nursing Clinical Practice for Dengue Hemorrhagic Fever: Summary of Symptoms, Observation, Care, Treatment, and Precautions (For Nursing Students)
Hello, I am Takashi Harada. With 20 years of experience as a certified nurse in stroke rehabilitation and extensive involvement in student guidance, I will explain the key points for first-year nursing students that are truly useful for clinical practice and documentation, focusing on Dengue Hemorrhagic Fever.
[The case introduced here is a fictional scenario for learning purposes]
A patient model you might encounter during clinical practice
Ms. A, a 25-year-old woman. She returned from an overseas trip one week ago and has had a high fever, generalized joint pain, and a red rash on her skin for the past two days. She was resting at home, but visited the hospital due to persistent nosebleeds, bleeding gums, and black stools. She was diagnosed with Dengue Hemorrhagic Fever and admitted for management, and you have been assigned to handle her care and observation during your student clinical practice.
1. What is Dengue Hemorrhagic Fever? [Basic knowledge of the disease for clinical practice]
Dengue Hemorrhagic Fever (DHF) is a severe condition caused by infection with the dengue virus.
It is primarily transmitted to humans by mosquitoes (Aedes mosquitoes) in tropical and subtropical regions such as Southeast Asia and Central and South America.
About 1 to 5% of dengue fever patients develop the severe form, 'Dengue Hemorrhagic Fever'.
In Japan, it is common among returnees with a history of overseas travel, and in recent years, cases of domestic infection have also been reported occasionally.
Analogy: If you compare a mosquito to a 'delivery person,' it carries a 'package' called the dengue virus, and the person who receives it develops symptoms. Hemorrhagic fever is like a situation where 'the contents of the package are broken, damaging blood vessels throughout the body.'
2. Symptoms and Observation Points for Clinical Practice
Main Symptoms
High fever (persistent fever of 39–40°C)
Headache, pain behind the eyes, muscle pain, joint pain, and generalized malaise
Rash (patchy on the trunk, face, and limbs; petechiae and purpura are also common)
Nosebleeds, bleeding from gums, bloody stools, and abnormal menstrual bleeding
Nausea, vomiting, and abdominal pain
In severe cases, low blood pressure, shock, and impaired consciousness may also occur
Observation Points
Continuous observation of vitals such as body temperature, respiration, pulse, and blood pressure
Changes in bleeding sites, volume, and color (nose, gums, skin, stool, vomit, etc.)
Spread of rashes and presence of purpura or petechiae
Trends in fluid intake, urine output, and body weight (to assess dehydration and circulatory status)
Report abdominal pain, vomiting, or impaired consciousness immediately
Respond carefully to the concerns and anxieties of patients and their families
Student feedback: 'I compared and recorded Patient A's rashes and bleeding at the same time and site every day. I felt the impact of my records leading to changes in treatment and care.'
3. Treatment Flow and Basics of Care
Core of Treatment
Currently, there are no drugs or specific vaccines that act directly on the virus itself.
**Symptomatic treatment (rest, fluid replacement, antipyretics, analgesics)** is the mainstay.
To prevent rapid dehydration/shock, fluid management is extremely important.
Intensive care is required if signs of bleeding or shock appear.
Nursing and Care Points
Monitoring vital signs and signs of bleeding: Report and record changes immediately
Maintaining rest and environmental adjustment: Keep movement to a minimum, prevent falls and accidents
Checking fluid and electrolyte balance: Urine output, skin dryness, thirst, edema
Managing IV drips and blood draws: Compression hemostasis at puncture sites and observation for signs of bleeding
Skin and mucosal care: Be careful of friction and irritation as rashes and purpura form easily
Psychological support: Empathize with and encourage patients regarding their anxiety over 'risk of sudden change' and long-term bed rest, as well as inconveniences
Clinical practice episode: 'During a blood draw, I noted that Patient A was prone to bleeding and practiced applying pressure for a longer period to stop the bleeding. My instructor praised me, saying, "You have a good grasp of the observation points."
4. Challenges and Growth Nursing Students Often Experience in Clinical Practice
Struggling with "how much to observe and at what timing to report" the signs of shock or sudden bleeding
Difficulty choosing the right words when explaining the necessity of bed rest to the patient and their family
Noticing the difference in pressure and observation procedures after blood draws or IVs (longer and more reliable hemostasis than usual) and being able to put it into practice
Experiencing the realization that "my observations and records are directly linked to a patient's life"
Student feedback: "When Patient A complained of 'sudden lightheadedness,' I was able to coordinate with my senior nurse by providing hydration, taking vital signs, and reporting immediately. I realized once again that the speed of observation and action is crucial."
5. Care and Observation Examples & Precautions Useful for Clinical Practice
Perform vital sign measurements and skin observations frequently and compare them over time
Check if new bleeding sites have appeared, and record observations on their "color and size"
Continuously record vomiting, diarrhea, abdominal pain, and urine output to detect "signs" of dehydration early
Do not overlook even the "slightest redness" from bleeding at IV sites, mucous membranes, stool, or urine; record and report immediately
Share information on how to maintain bed rest and how to divide care tasks within the team during mini-conferences
When explaining to family members, also include the importance of "mosquito-borne infection" and "infection prevention and control"
6. Q&A: Frequently Asked Questions
Q. What is the difference between dengue hemorrhagic fever and dengue fever?
A. Dengue fever presents with relatively mild symptoms such as fever, rash, and muscle pain, whereas hemorrhagic fever causes severe bleeding and shock due to thrombocytopenia and increased vascular permeability.
Q. What are the observation points and recording methods for clinical practice?
A. Focus on "chronological and evidence-based records," including changes in vitals, bleeding sites, skin symptoms, urine output, fluid intake, nausea/vomiting, and patient complaints.
Q. What should nursing students be careful about regarding care and treatment?
A. Preventing bleeding during blood draws and IVs, reporting sudden drops in blood pressure, early detection of dehydration signs, psychological support, and infection control measures (including guidance for patients and families).
Q. Are there any aftereffects or recurrences of dengue hemorrhagic fever?
A. While most patients recover with appropriate care, in rare cases of severe illness, liver damage or serious complications may remain, and it is said that the risk of severe illness increases with reinfection.
7. Conclusion: A Message to Nursing Students
In nursing for dengue hemorrhagic fever, the keys to growth are "early detection of bleeding and dehydration," "thorough observation of vitals and symptoms," "the ability to record and report even the smallest changes without missing them," and "kind explanations and preventive guidance for patients and their families." Please experience many "realizations" during your clinical practice that lead to safe and secure nursing.
