Abstract:
Objective:To investigate the epidemiology and clinical features of pulmonary hemorrhage in children at pediatric intensive care unit(PICU).
Methods:A retrospective cohort case analysis was performed in order to investigate the incidence, primary disease, clinical manifestations and clinical characteristics of pulmonary hemorrhage in children at PICU of Shengjing Hospital of China Medical University from January 2008 to September 2017.
Results:Among the 73 cases, 39 cases were male (53.4%) and 34 cases were female(46.6%), and the average age was 31(5, 72)months.The conditions of 14 cases(19.2%) were improved and discharged, 17(23.3%) cases died during the hospitalization period, and 42 cases gave up treatment halfway.The primary causes of pulmonary hemorrhage included severe heart failure in 17 patients (23.3%), acute respiratory distress syndrome (ARDS) in 12 patients (16.4%), severe sepsis in 10 patients (13.7%), hematological diseases in 10 patients (13.7%), intracranial hemorrhage occurred in 5 patients (6.8%), cardiac arrest in 5 patients (6.8%), coagulation dysfunction in 5 patients(6.8%), renal disease in 3 patients(4.2%) and other diseases in 6 patients(8.3%). The symptoms of all cases (73 cases) of pulmonary hemorrhage included dyspnea, moist rales and decreased blood oxygen saturation.Nasal bleeding or coffee ground like material drawn out from nasal stomach tube could be found in 32 cases(43.8%, 32/73 cases), 36 cases(49.3%, 36/73 cases)were complicated by shock and 9 cases (12.3%, 9/73 cases) were combined with convulsions, and 47 cases (64.4%, 47/73 cases) were given cardiopulmonary resuscitation.The positive end expiratory pressure in ARDS group was(10.2±2.4) cmH2O(1 cmH2O=0.098 kPa), which was higher than that in other groups (F=4.59, P<0.01). The oxygen concentration in acute respiratory distress syndrome group was(0.9±0.1)% , which was higher than that in other groups (F=3.16, P<0.01). International normalization ratio was 1.9±0.7 in severe sepsis group, which was higher than that in other groups (F=2.96, P<0.01). Blood platelets in hematological disease group was (52.0±46.8)×109/L, which was lower than that in other groups (F=8.23, P<0.01) and hemoglobin in hematological disease group was (81.6±15.6) g/L, which was lower than that in other groups (F=5.48, P<0.01). Chest X-ray examinations showed decreased lung permeability, multiple exudative lesions in 61 cases and increased bronchovascular shadows in 5 cases.
Conclusions:Pulmonary hemorrhage may be a complication of many diseases. Severe heart failure, ARDS, severe sepsis and hematological diseases are the first four primary causes of pulmonary hemorrhage at PICU. Different causes of pulmonary hemorrhage manifest different characteristics.If the symptom of a patient shows heart rate increase, dyspnea, moist rales and blood oxygen saturation decreased with bleeding tendency and pulmonary infiltration by chest X-ray, he can be suspected of pulmonary hemorrhage.
