Dengue Fever: Nursie!

Dear Auntie:

If you or someone you love has dengue, you may want to know what the nurse who is at your bedside most of the day is doing to take care of you.



Let's talk about the major priorities of nursing care for patient's with Dengue Fever.

Nurses are primarily concerned about managing the side effects of the disease while other treatments given to you by physicians help to stop the dengue virus from spreading in your body.

Let's talk about what the nurse might do to help manage the symptoms of dengue:
1. Nausea,vomiting: The nurse might offer a prescribed medication to help control these feelings and assist the dengue patient to find a diet that they can tolerate that does not cause feelings of nausea.
2. Constipation: The nurse will suggest walking to help relieve constipation
3. Bleeding: The nurse will look for the source of the bleeding and stop it if possible. However, with dengue the bleeding may be from multiple sources or internal. In that case, the nurse will administer IV saline or red blood cells by order of the physician. The nurse will also try to minimize chances for bleeding by having the patient brush his or her teeth with a soft tooth brush or soft sponge, reduce the chances of the patient falling and bruising himself, offer stool softeners (not to the extent that the patient gets diarrhea), the nurse will also suggest that the patient try not to blow the nose to prevent nose bleeds.
4. Joint and Muscle Pains: The nurse will offer inflammation reducing medications by order of the physician, such as acetaminophen or ibuprofen. These may help to reduce the pain. The nurse will also suggest a mixture of warm and cold on the joints to help reduce the pain.
5. Signs of Shock: The nurse will monitor your blood pressure, temperature, pulses, and capillary refill time frequently to ensure that the fluid volume in the body is not so low that the patient is going into hypovolemic (too little volume) shock. The nurse will also monitor anxiety level because this can be a sign of shock. If the nurse feels that the fluid volume in the body is too low based on these indicators, normal saline will be given through an IV.

Those are just some of the things the nurse will be doing at the bedside to take care of anyone with dengue fever. The goal is to prevent bleeding, fluid loss, and shock as well as reduce the amount of dengue virus in the body so that the patient begins to feel better and can be sent home from the hospital.

Dengue Fever: Treatment

Dear Auntie:

I know all this talk about Dengue Fever has you worried. The following is the flow-chart clinicians use to determine the clinical picture for a patient with dengue.

That is super complicated and scary! So let's talk about treatment in place and simple terms.

Dengue patients are categorized into three groups - Group A, group B, and group C.

Patients in Group A may be sent home while they recover. Patients are categorized intro group A if they can take oral fluids and pass urine at least every 6 hours. These patients require a lot of rest too. They may be offered acetaminophen (tylenol) at no more than 4 grams a day to manage the pain and other side effects of acute infection, but generally it will resolve on its own with adequate rest and hydration.

Patients in Group B require encouragements and close monitoring for oral fluid intake to prevent dehydration. They may need IV fluid therapy with normal saline to keep their fluid volume in the blood at an appropriate level and prevent dehydration if they cannot drink enough fluid. After the fluid volume is correct, as evidenced by a normal blood pressure and heart rate, the patient can be sent home just like a Group A patient.

Patients in Group C have a more difficult course of treatment, usually in the hospital. These patients are generally hemorrhagic, so they are losing a lot of blood. They require an IV to be started right away for administration of either normal saline OR a blood transfusion. If a lab value called the hematocrit is low, they need blood that is type and cross matched to their blood in order to save their life. They will continue receiving blood until their hematrocrit starts to increase and remain stable without blood transfusions. The patient can be sent home, like a group A patient, when their hematrocrit is stable and they are able to manage without IV fluids.

Aunite, the very best treatment for Dengue Fever is prevention! We really want to keep from getting sick altogether. The following video outlines some basic Dengue Fever prevention strategies.
