Akut Astım Atağı Nedeniyle Yoğun Bakımda Takip Edilen Hastaların Özellikleri

Abstract

Asthma attack is a serious reason for morbidity and mortality when it is not treated effectively at the right time. The data about efficiency of noninvasive mechanical ventilation in respiratory insufficiency due to asthma attack are scant. In this study we investigated if there is a relation between age, sex, comorbidities, asthma duration, asthma treatment, compliance to this treatment, NIV/IMV treatment efficiency if performed and its relation with severity of asthma attack, length of hospital stay and mortality. In this study we investigated the characteristics of patients with severe asthma who were treated in Hacettepe University Medical Intensive Care Unit(ICU) between January 2002 and December 2012 by reviewing the patients’records retrospectively. A total of 22 patients were included in this study. Besides medical treatment, noninvasive positive pressure ventilation (NPPV) was provided to 8 (36.6%), invasive mechanical ventilation was to 5 (22.7%) and both were provided to 5 (22.7%) patients. Four (18.1%) patients died in the ICU. In conclusion, we did not observe any relation between these parametres and length of hospital stay and mortality. Only the first and the difference of PaCO2, pH and HCO3¯ changes were significant which shows the correct and effective use of NIV/IMV. There was no relation between these and mortality which revealed that the reasons of death of the patients were not respiratory, but rather infection or comorbidity.
