Informant: Mother % Reliability: 90%

I. General Data L.N. is a 13 days old, male, Filipino, Roman Catholic, born in Punta, Sta. Ana, Manila on December 27, 2005. He is presently residing at 1880-B Mayon St. Punta, Sta. Ana, Manila. He was admitted for the first time at OMMC on January 5, 2005 at about 9:00 am.

II. Chief Complaint Bleeding Umbilical Stump

III. History of Present Illness 17 hours PTA, the mother noticed that the patient’s umbilical stump was bleeding. According to her, it was continuously bleeding but the blood flow is of small quantity. She immediately cleaned it with Povidine Iodine (Betadine) many times but the bleeding did not stop. This prompted her to consult to the midwife who recommended her to apply Fusidic acid cream 2% (Fucidin) onto the patient’s umbilical stump. After several applications, the bleeding still would not stop, so the mother discontinued using it. The patient has no history of fever, vomiting and dyspnea. There were no other sites of bleeding noted. 13 hours PTA, the patient’s umbilical stump is still continuously bleeding, this time, in increased blood flow quantity. The mother only cleaned it with Povidine Iodine (Betadine) but it didn’t stop the bleeding. 9 hours PTA, the patient’s umbilical stump was still continuously bleeding. The mother then decided to seek consult to PGH. According to the doctor, it was just a peeled wound crust in the umbilicus and so the doctor only cleaned the wound and put a thick gauze pad on the patient’s umbilicus, and then sent them home. There were no other procedures done and no medications were given to the patient. The mother was not sure if the bleeding did stop because she did not inspect it anymore and went to sleep. 3 hours PTA, when the mother checked the wound dressing, she said it was already soaked with blood. She also noticed some drops of blood on the sides of the patient’s abdomen. She only cleaned the umbilicus and changed the wound dressing but it didn’t stop the bleeding. 1 hour PTA, patient’s umbilical stump is still continuously bleeding. The mother rushed him to OMMC and was subsequently admitted.

Bleeding umbilical stump Patient was born full term Patient is a neonate, 13 days old, male Patient is breastfed since birth Patient was not injected intramuscularly with Vitamin K at the time of birth

IX. Differential diagnoses Disease Hemorrhagic Disease of the Newborn resulting from deficiency in vitamin K Rule In  A moderate decrease of factors II, VII, IX and X normally occurs in all newborn infants by 48-72 hours after birth, with a gradual return to birth levels by 7-10 days of age. Prolongation results to spontaneous and prolonged bleeding.  Breast milk is a poor source of vitamin K, and hemorrhagic complications have appeared more commonly in breast-fed than formula-fed infants.  The disease is characterized by bleeding that tends to be gastrointestinal, nasal, intracranial.  Administering 1 mg of natural oil-soluble vitamin K intramuscularly at the time of birth prevents the fall in vitamin K-dependent factors in full-term infants. Rule Out

Hemophilia A

 Hemophilia A is an X-linked recessive disorders; therefore, they affect males almost exclusively.  Factor VIII does not cross the placenta, hence, bleeding tendency is evident in the neonatal period.  Significant deficiency in FVIII or FIX may be evident in the neonatal period and continue through the life of the affected individual.  At birth, neonates may present with prolonged bleeding from the cord or umbilical area.

 In 80% of cases, family history is positive for the disease.  Hematomas are common after injections or minor trauma.  The hallmark of hemophilia is hemarthrosis.

Disseminated Intravascular Coagulation

 The highest incidence of DIC is in the neonatal period.  There may be bleeding in the umbilical stump.

 More common in premature infants.  DIC usually occurs in the context of respiratory distress syndrome and sepsis.  Highly suspect presence of infection.  The patient's general appearance frequently is toxic.  The clinical picture is commonly one of bleeding with signs of shock out of proportion to the amount of blood loss, with poor perfusion, cold extremities, and poor tone in the neonate.  Purpura fulminans (severe, extensive hemorrhage into the skin associated with fever and hypotension) caused by infections (especially

meningococcemia), protein C deficiency, or cutaneous purpuric or hemorrhagic lesions may develop and spread rapidly, which may progress to frank gangrene.  DIC often is accompanied by renal, hepatic, pulmonary, or CNS manifestations; most patients are critically ill.

X. Diagnosis Hemorrhagic Disease of the Newborn resulting from vitamin K deficiency.

XI. Treatment Lab Studies:  Include prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen levels, and a platelet count in the initial workup for bleeding in a newborn. A thrombin clotting time (TCT) is optional. o A prolonged PT usually is the first laboratory test result to be abnormal in VKDB; however, no laboratory test can confirm the diagnosis of VKDB. Vitamin K direct assay is not useful because levels normally are low in newborns. Levels of protein induced by vitamin K antagonism (PIVKA) II are increased in VKDB, but this test generally is not available outside of research laboratories. Infants with VKDB typically have a prolonged PT with reference range platelet counts and fibrinogen levels. Thrombocytopenia or a prolonged aPTT should prompt workup for other causes of bleeding.



The diagnosis of VKDB is confirmed if administration of vitamin K brings a halt to the bleeding and reduces the PT value.

Imaging Studies:



Intracranial bleeding is rare and usually associated with other causes of bleeding, particularly the thrombocytopenias; however, ICH has been reported in VKDB and can be fatal. Investigate any neurologic symptoms with a CT scan

Medical Care:  Immediately administer a vitamin K SC dose for any infant in whom VKDB is suggested or with any sort of bleeding. o o  IM administration can result in a hematoma because of the coagulopathy. IV administration of vitamin K has been associated with anaphylactoid reactions.

Fresh frozen plasma may be considered for moderate-to-severe bleeding. o o Life-threatening bleeding may also be treated with prothrombin complex concentrates (PCC). Because the bleeding in classic VKDB usually is not life threatening, a single dose of parenteral vitamin K is sufficient to stop the bleeding and return PT values to the reference range.

Administering 1 mg of natural oil-soluble vitamin K intramuscularly at the time of birth prevents the fall in vitamin K-dependent factors in full-term infants but is not uniformly effective in the prophylaxis of hemorrhagic disease of the newborn in premature infants. The disease may be effectively treated with an intravenous infusion of 1-5 mg of vitamin K1, with improvement of coagulation defects and cessation of bleeding within a few hours. However, serious bleeding, particularly in premature infants or those with liver disease, may require a transfusion of fresh frozen plasma or whole blood. The mortality rate is low among treated patients. A particularly severe form of deficiency of vitamin K-dependent coagulation factors has been reported in infants born to mothers receiving anticonvulsive medications during pregnancy. There may be severe bleeding with onset within the first 24 hours of life, which is usually corrected by vitamin K1, although in some, the response is poor or delayed. A prothrombin time (PT) should be obtained on cord blood and the infant given 1-2 mg of vitamin K intravenously. If the PT is greatly prolonged and fails to improve, 10 ml/kg of fresh frozen plasma should be given.
