ABSTRAKLatar belakang dan tujuan: Modalitas radiografi toraks merupakan pemeriksaan
rutin dan tersedia di hampir setiap rumah sakit. Pengukuran secara kuantitatif
berupa vascular pedicle width (VPW), cardiothoracic ratio (CTR) maupun
vascular pedicle-thoracic ratio (VPTR) melalui radiografi toraks dapat membantu
dalam membedakan jenis edema paru dengan mengetahui titik potong rerata
VPTR berdasarkan kombinasi VPW dan CTR.
Metode: Penelitian dilakukan retrospektif dengan descriptive cross sectional pada
100 pasien dengan klinis edema paru yang telah melakukan radiografi toraks di
ICU Rumah Sakit CiptoMangunkusumo (RSCM) dalam rentang waktu Januari
2013 ? Desember 2015. Subjek dibagi menjadi edema kardiogenik dan non
kardiogenik berdasarkan kombinasi pengukuran VPW dan CTR. Kemudian
dilakukan pengukuran VPTR dan ditentukan titik potong rerata VPTR, sensitivitas
dan spesifisitas berdasarkan kombinasi VPW dan CTR dalam membedakan edema
paru.
Hasil: Dari total 100 subjek penelitian di ICU RSCM dengan metode Receiver
Operating Curve (ROC) didapatkan titik potong VPTR sebesar 25,1% dengan
sentivitas 90,5% dan spesifisitas 86,1% dalam membedakan edema paru
kardiogenik dan non kardiogenik. Selain itu diperoleh juga proporsi edema paru
kardiogenik sebesar 21%, sedangkan edema paru non kardiogenik sebesar 79%.
Kesimpulan: Titik potong VPTR berdasarkan kombinasi VPW dan CTR memiliki
sensitivitas dan spesifisitas yang cukup tinggi dalam membedakan edema paru
kardiogenik dan non kardiogenik.
ABSTRACTBackground and purpose: Pulmonary edema in critically ill patient were
challenging in intensive care unit (ICU). Radiography of thorax is routine
examination and widely available in almost every hospital. Measurement
quantitatively of vascular pedicle width (VPW), cardiothoracic ratio (CTR) and
vascular pedicle-thoracic ratio in thorax radiography can help in differentiating
the type of pulmonary edema through the cut off of VPTR based on combination
VPW and CTR.
Methods: Descriptive cross sectional restrospective in 100 patients with clinically
pulmonary edema which have examined by thorax radiography at ICU RSCM in
January 2013 to Desember 2015. Subject divided to cardiogenic and non
cardiogenic pulmonary edema based on combination VPW and CTR. Then,
VPTR were measured and the cut off of VPTR determined based on combination
VPW and CTR in differentiaiting pulmonary edema.
Results: From total 100 subject study at ICU RSCM using Receiver Operating
Curve (ROC) metode, the cut off of VPTR is 25,1% with sensitivity 90,5% and
specificity 86,1% in differentiating cardiogenic and non cardiogenic pulmonary
edema. Beside that, the prevalence of cardiogenik pulmonary edema is 21% and
non cardiogenic pulmonary edema is 79%.
Conclusion : The cut off of VPTR based on combination VPW and CTR have
significant sensitivity and specificity in differentiating cardiogenic and non
cardiogenic pulmonary edema."
