AMAÇ: Spinal immobilizasyon cihazlarýnýn solunum fonksiyonlarý üzerindeki etkileri araþtýrýldý.
GEREÇ VE YÖNTEM: Bu çalýþma, saðlýklý gönüllü kiþilerde yapýlan kesitsel bir çalýþmadýr, 60 gönüllü dahil edildi. Yatar pozisyondayken tam spirometre uygulandý ve tüm deneklerde zorlu vital kapasite (FVC), zorlu birinci saniye ekspiratuvar hacim (FEV1) ve FEV1/FVC kaydedildi. Sonra, Philadelphia tipi boyunluk (Philly) ve travma yeleði (Kendrick extrication device=KED) tüm deneklere uygulandý. Boyunluk ve KED uygulamasýndan sonra 5. ve 30. dakikada tüm deneklerde FVC, FEV1 ve FEV1/FVC ölçüldü. Bir saat dinlenme zamanýndan sonra, tüm deneklere Philly ve uzun omurga tahtasý tekrar uygulandý. Boyunluk ve uzun omurga tahtasý uygulandýktan sonra tüm deneklerde 5. ve 30. dakikada FVC, FEV1 ve FEV1/FVC ölçüldü.
BULGULAR: Bazal deðerler KED uygulandýktan sonra ölçülen 5. ve 30. dakika deðerleri ile karþýlaþtýrýldý. KED uygulandýktan sonra FEV1 (p=0,000) ve FVC deðerlerinde (p=0,000) önemli derecede istatiksel anlamlý düþme bulundu, ama FEV1/FVC deðerlerinde belirgin deðiþiklik yoktu. Uzun omurga tahtasý uygulandýktan sonra 5. ve 30. dakikada ölçülen deðerleri bazal deðerlerle karþýlaþtýrýldý. Uzun omurga tahtasý
uygulandýktan sonra FEV1 (p=0,000) ve FVC deðerlerinde (p=0,000) önemli derecede istatiksel anlamlý düþme bulundu, fakat FEV1/FVC deðerlerinde belirgin deðiþiklik
yoktu.
SONUÇ: KED ve uzun omurga tahtasýnýn solunum fonksiyonlarýný azalttýðýný belirledik.

Anahtar Kelimeler: Travma tahtasý, travma yeleði; akciðer fonksiyonu; omurga sabitleme

BACKGROUND: We aimed to investigate the effects of spinal immobilization devices on pulmonary functions.
METHODS: This study was a cross-over trial in healthy volunteer subjects; 60 volunteers were included. We performed a full spirometry in the supine position, and forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and FEV1/FVC were recorded in all subjects. Then, Philadelphia type cervical collar (Philly) and Kendrick extrication device (KED) were applied to all subjects. We measured FVC, FEV1, FEV1/FVC in all subjects in the supine position at the 5th and 30th minutes after application of cervical collar and KED. After a one-hour relaxation period, Philly
and long spinal backboard with straps were applied to all subjects. FVC, FEV1, FEV1/FVC were measured again in all subjects at the 5th and 30th minutes after application of
cervical collar and long spinal backboard.
RESULTS: After application of KED, baseline levels were compared with levels at the 5th and 30th minutes. Statistically significant decreases were determined in FEV1 (p=0.000) and FVC levels (p=0.000) after application of KED, but there were no significant differences in FEV1/FVC levels. After application of the long spinal backboard, a comparison of baseline levels and levels at the 5th and 30th minutes demonstrated statistically significant decreases in FEV1 (p=0.000) and FVC levels (p=0.000), but no significant difference in FEV1/FVC levels.
CONCLUSION: We determined that both KED and long spinal backboard cause a decrease in pulmonary functions.
