Abstract

Amaç: Karbonmonoksid (CO) zehirlenmelerine, özellikle soğuk
havalarda olmak üzere acil servis birimlerinde sıklıkla karşılaşılır.
Çalışmamızda, bazı meteorolojik faktörlerin CO zehirlenmesinin kaynakları ile
ilişkisini araştırdık.

Yöntem: Retrospektif gözlemsel çalışmamızda, son üç yılda acil servise
CO zehirlenmesi ile başvuran 1153 hastayı dahil edildi. Bölgenin atmosferik
basıncı, rüzgarın yönü ve hızı, nem düzeyi ve hava sıcaklığı değerleri ve CO
zehirlenme tipi karşılaştırıldı.

Bulgular: Hastaların yaş ortalaması 39,5±16,3; kadın cinsiyet %65,7
(n=761) idi. CO kaynağının kaynağı en sık doğalgaz ısıtıcıları (n=628; %54,4);
daha sonra ocak (n=393; %34,1), şofben (n=94; %8,4) ve yangındı (n=38; %3,3).
En sık görülen rüzgar yönü kuzey-kuzeydoğu yönü (poyraz)idi. Atmosferik basınç
tüm zehirlenme tiplerinde benzerdi. Yangınlarda nem düzeyleri istatistiksel
anlamlı düşüktü ve hava sıcaklığı anlamlı yüksekti. Rüzgar hızı yangın tipinde
en hızlı ve şofben tipinde en yavaştı.

Sonuç: Karbonmonoksid zehirlenmeleri ciddi morbidite ve mortaliteye
neden olabilen acil servis başvuru nedenlerindendir. Başlıca nedeni ev
ısıtıcılarıdır. Risk altındaki insanlar CO zehirlenmeleri hakkında ve önemli
meteorolojik değişikliklerde ısıtıcaların riskleri hakkında
bilgilendirilmelidir. Zehirlenme bulguları görüldüğünde acil servise
başvurulmalıdır.

The Effect of Carbonmonoxide Sources and Meteorologic Changes in Carbonmonoxide Intoxication: A Retrospective Study

Abstract

Objective: Carbon monoxide (CO)
poisoning is frequently seen in emergency departments (ED) especially in cold
weather. We investigated the relationship of some of the meteorological
factors with the sources of CO poisoning.

Methods: In this
retrospective observational study, we included 1153 patients who were admitted
to ED due to CO poisoning in a three year period. Atmospheric pressure, wind
direction and speed, humidity level and air temperature of the region at
exposure time were compared with CO poisoning type.

Results: Mean age of the
patients was 39.5±16.3; females were 65.7% (n=761) of the patients. Most
frequent source of CO was natural gas heaters (n=628; 54.4%); others were
stove (n=393; 34.1%), geyser (n=94; 8.4%) and blaze (n=38; 3.3%). Most
frequent direction of the wind was North-North-East (euroclydon). Atmospheric
pressure was similar in all of the poisoning types; in blaze, humidity levels
was significantly lower, air temperature was significantly higher. Wind speed
was faster in blaze and slowest in geyser type poisoning.

Conclusion: Carbon monoxide
poisoning is an important cause of emergency visits which can result in
serious morbidity or mortality. Main sources are home heating systems. People
should be informed about the risks of these heaters and symptoms of CO
poisoning and also in case of important meteorological changes. They should
apply to an ED in case of occurrence of intoxication symptoms.
