96 cases of croup were clinically observed for 8 years from 1960 to 1967. The summary of the clinical and laoaratory findings are as follows:
Analysis of the yearly prevalence revealed 62% of cases in 1967, which seems sufficient to reflect clear epidemic pattern. A preponderance of cases (83 cases, 86%) occured between December and March. Most frequent month was February (25 cases, 26%). This reflects the pattern of admission to this hospital for other acute respiratory disease. The most frequent age group was early childhood in the range of 3-5 years of age (51 cases, 53%) with the sex ratio of male 1, 3: female 1. Almost all cases developed in Cholla Puk Do, suggesting strongly the evidence of local epidemic and more frequently in rural area(57 cases, 59.3%). Most of the patients (77.1%) visited and admitted to the hospital within 48 hours after the initial complaints. The clinical picture is characterized by an abrupt onset, fulminating course, difficulty in breathing (90.6%), hoarseness (85.4%), barking cough (71.9%), larygeal stridor(50. 0%)and etc. The course, if untreated, is usually rapidly disastrous over the next several hours, resulting rapidly progressive respiratory obstruction, onset of cyanosis, shock and death shortly thereafter. Upon examination, there was definite swelling and redness of tonsils, pharynx and epiglottis (92%). Significant retraction of the intercostal spaces and of the accessory respiratory muscles was apparent in 58% of cases. Other findings are as follows:
Coarse breathing sound (43. 8%), excessive mucus in posterior pharynx (37. 5%), pseudomembrane (20%) and etc. Cervical adenitis was not so popular. On the peripheral blood counts, 80.2% of the patients had mild to moderate degree of anemia and polymorpho leukocytosis was detected on the 84. 4% of the cases with the range of 10, 000-25, 000/mm3. Corynebacterium diphtheriae and Hemophilus Influenzae were never detected in any of the cases. Throat smear and culture yielded streptococci (70.4%), staphylococci (11.3%), micrococcus tetragenus (5.6%) and etc. Immediately on admission to the hospital all patients were placed in a humidified atmosphere, given general supportive theraphyj and kept under constant nursing and medical surveilance. T.acheostomy was carried out on 40.6% of the patients. The cornerstone of treatment for the respiratory obstruction was tracheostomy in our experiences. It is our pinion that 2 cases of 4 death in this series rnight have been prevented by early tracheostomy. Bronchopneumonia was found in 43. 8% of cases by chest X-ray. Mild pneumoniediastimim (3. T%) and subcutaneous ernphysema(2. I%) were complicated during tracheostomy. 4 cases (4.2%) were expired.
