Technical Modification of Routine Chest Radiography for Pneumothorax detection

บทคัดย่อ

Abstract

           This study is applied research. From the problem of detecting Pneumothorax pathology in secondary hospital is the lack of standard equipment like a computed tomography. The ability of chest radiography to determine Pneumothorax pathology depends on position and exposure technique. The early and accurate diagnosis of Pneumothorax is essential in preventing respiratory failed and potential death. Thus this study aimed to modify chest x-ray technique and study in 2 positions CXR PA upright compare with CXR AP supine for Pneumothorax detection. To constructed CXR modified technique for chest x-ray 16 patients with suspected Pneumothorax were recruited.
The method CXR modified technique was used in patient x-ray. Collect data using Pneumothorax evaluation form. Interpreted result by four individual readers in blinded test method. Evaluation of CXR modified technique for Pneumothorax detection by sensitivity, specificity and accuracy. The results show sensitivity of CXR modified in detecting pneumothoraxes is 70%, 60%, 60% and 80% respectively. Specificity of CXR modified is 67%, 50%, 83.33% and50%. Accuracy value is 68.75%, 56.25%, 68.75% and 68.75% respectively.  A Pneumothorax was detected 90% (9 of 10). In summary, this study indicated that the developed of CXR modified technique is beneficial for patients to early and accurate detection Pneumothorax.
