Clinical contrast analysis of spontaneous pneumothorax between senile and youth

Abstract

Objective To enhance recognition of pneumothorax of the senile by contrasting the clinical features of pneumothorax between the senile and the youth.Methods Contrasting the cause,inducement,clinical manifestation,type of pueumothorax,treatment method,complication,misdiagnosis rate and mortality of pneumothorax between the senile group(age≥60 years old,n=58)and the youth group(age≤40 years old,n=121).Results The ratio of secondary pneumothrax in the senile group was higher than that in the youth group(100%vs 29.8%,P＜0.01).Patients in the senile group had a significantly low ratio of inducement compared to those in the youth group(19.0%vs 42.1%,P＜0.01).The clinical manifestation:the incidence of chest pain and tachypnea,cough in the senile group and youth group were 41.4%vs 72.7%(P＜0.01)and 91.4%vs 20.7%(P＜0.01),96.6%vs 81.8%(P＞0.01),respectively.The tension pneumothorax in the senile group was more than that in youth group(21 vs 0)(P＜0.01).The thoracic close drainage in the senile group was more than that in youth group(81.0%vs 43.0%)(P＜0.01).The complication,misdiagnosis rate and mortality of the pneumothorax in the senile group were higher than those in the youth group(44.8%vs 9.1%,P＜0.01;25.9%vs 2.5%,P＜0.01 and 6 vs 0,P＜0.01).Conclusions As for pneumothorax in the senile,of which primary affection is COPD,the clinical manifestation features are less chest pain,more tachypnea and complication,higher misdiagnosis rate and mortality.
