Acil Servise Nefes Darlığı İle Başvuran Hastaların Arter Kan Gazı Değerlerinin Noninvaziv Yöntemle Ölçülen Kan Gazı Değerleri İle Karşılaştırılması

Öz

Amaç

Çalışmamızda nefes darlığı ile başvuran hastalarda invaziv (arter) ve non-invaziv (transkütan) kan gazı sonuçlarını karşılaştırarak, non-invaziv kan gazı ölçümünün klinik kullanıma uygunluğunun belirlenmesi amaçlandı.

Materyal-Metod

Çalışmamızda dispne sebebiyle acil servise başvuran ve arteriyal kan gazı çalışılan 234 hasta dahil edildi. Hastaların tensor Tip MTX-Matrix cihazı ile parmak ucu sO2, PO2, PCO2 ve pH değerleri ölçülerek arteriyal kan gazı ile karşılaştırıldı. Sürekli verilerin normal dağılımının test edilmesinde Kolmogorov Smirnov testi kullanıldı. Grupların karşılaştırılmasında Wilcoxon testi kullanıldı. İnvaziv

(arter) ve non-invaziv (transkütan) kan gazı sonuçlarının uyumunu test etmede Bland Altman testi kullanıldı. Sonuçlar % 95’lik güven aralığında, anlamlılık p<0.05 düzeyinde değerlendirildi.

Sonuçlar

Çalışmamızda 234 hastanın yaş ortalaması 69,0±18,1 yıl olup, hastaların%42,7’si erkekti. Hastalarda dispne dışında belirlenen en sık semptom göğüs ağrısı, en sık saptanan tanı pnömoniydi. Arter kan gazı (AKG) ölçülen pH yerine, transkütan pH kullanılabileceği saptandı (p>0,05). AKG’de

ölçülen PCO2, PO2 ve sO2’nin yerine, transkütan PCO2, PO2 ve sO2 kullanılamayacağı saptandı (p<0,05).

Tartışma

Sonuç olarak transkütan olarak kan gazı parametrelerini değerlendirilen cihazlar dispneik hastalarda pH yerine kullanılabilir. Tüm kan gazı parametrelerinin değerlendirilmesi için cihazın geliştirilmesi gerekmektedir.

Comparison of Artery Blood Gas Values Measured Versus Noninvasive Blood Gas Values Measured Method in Patients With Dyspne to Admitted Emergency Department

Abstract

Purpose

We aimed to determine the suitability of non-invasive blood gas measurement for clinical use by comparing the results of invasive (arterial) and non-invasive (transcutaneous) blood gases in patients with dyspnea in our study.

Material and Methods

In our study, 234 patients were included who referred to emergency services due to dyspnea and whose arterial blood gas were measured. Tensor Type MTX-Matrix device was used to measure patients’ fingertip sO2, PO2, PCO2 and pH values and these values were compared with arterial

blood gases. Kolmogorov Smirnov test was used to test the normal distribution of continuous data. The Wilcoxon test was used to compare groups. The Bland Altman test was used to test the compatibilitiy of invasive (arterial) and non-invasive (transcutaneous) blood gas results. The

results were evaluated in a confidence interval of 95% and a significance level of p <0.05.

Results

The mean age of 234 patients in our study was 69.0 ± 18.1 years and 42.7% of the patients were male. The most frequent symptom except for dyspnea was chest pain, the most

common diagnosis was pneumonia. It was determined that transcutaneous pH could be used instead of pH measured in arterial blood gas (ABG) (p>0.05). It was found that, transcutaneous PCO2, PO2 and sO2 could not be used instead of PCO2, PO2 and sO2 level measured in ABG (p

<0.05).

Results

As a result, devices that evaluate blood gas parameters as transcutaneously can be used instead of pH in dyspneic patients. For the evaluation of all blood gas parameters, the device needs to be improved.
