Abstract

Amaç: 
Bu çalışmadaki amaç kardiyopulmoner bypass sırasında bir grup hastayı
%10 volüm diğer grup hastayı solunumu tamamen durdurularak pre-op ve bypass
sonrası TAS (Total Antioksidan Kapasite), TOS (Total Oksidatif Durum), OSİ (Oksidatif
Stres İndeksi) bakılarak Akciğer ventilasyonun Bypass sırasında gerekliğinin
belirlenmesidir.

Materyal ve Metod: Göğüs Kalp
Damar Cerrahisi bölümünde çeşitli sebeplerden dolayı kardiyopulmoner bypass
cerrahisi ile ameliyat olan toplam 30 (14 E + 16 K) hasta seçildi. Hastalar 2
gruba (akciğer ventilasyonu tamamen durdurulan grup ve akciğer %10 cc volum ile
çalıştırılan grup)  ayrıldı. İki gruba
ayrılan hastalardan kardiyopulmoner bypass öncesinde, pompaya giriş sırasında,
pompadan çıkış sırasında ve ameliyat sonrası olmak üzere toplam 4 jelsiz tüpe
kan alınarak bir çalışma grubu oluşturuldu. Alınan kanlar santrifüjde ayrıştırıldıktan
sonra plazmaları -80 °C’de saklanarak numunelerin çalışma gününde Erel
yöntemiyle Total oksidatif stress, Total antioksidan kapasite ve oksidatif
stres indeks çalışıldı.

Bulgular: TAS değeri 1,0945±0,25, TOS değeri
15,38±6,10 ve OSi değeri 1,4827±0,67 olarak bulunmuştur. Ventile edilmeyen
hastaların TAS değeri 1,1514±0,24, TOS değeri 25,73±9,25 ve OSi değeri
2,2993±0,85 olarak bulunmuştur. Hastalarda TOS değeri ventile edilmeyen
hastalarda artmıştır. Çalışmamızdaki TOS değerindeki artış TAS değeri üzerinde
herhangi bir değişiklik oluşturmamıştır. OSİ değeri üzerinde anlamlı fark
oluşmuştur. (p<0.05)

Sonuç: iki grup karşılaştırıldığında TAS
değerinde anlamlı bir değişkenlik olmazken, TOS ve OSİ değerleri açısından
anlamlı bir sonuç çıkmıştır. KPB sırasında ventile edilmeyen hastalar % 10
ventile edilen hastalara göre TOS ve OSİ değerleri yüksek ve anlamlı
bulunmuştur. Bu durum bize KPB sırasında % 10 ventile edilen hastalardaki
oksidatif stres parametrelerinin azaldığını göstermektedir.

The effect of lung ventilation on total oxidative condition, total antioxidant capacity and oxidative stress index during cardiopulmonary bypass

Abstract

Background:The aim in this study is to obtain the necessity
of pulmonary ventilation during cardiopulmonary bypass by starting respiration
of a group of patients with 10% volume and the other group stopping respiration
totally as well as by examining TAS (Total Antioxidant Status), TOS (Total
oxidative status), OSİ (oxidative stress index) in pre-op and after bypass. 

Methods:Totally 30 patients (14
M+ 16 F) that had cardiopulmonary bypass surgery in Thoracic and Cardiovascular
Surgery Department for various reasons, were chosen. The patients were
seperated into 2 groups (as pulmonary respiration was stopped completely and
pulmonary respiration was started by 10% cc volume). Before carrdiopulmonary
bypass working group was formed among patients seperated into 2 groups by
taking totally 4 tubes of blood before cardiopulmonary bypass, at pump inlet,
pump outlet and after operation. After eluting taken blood in centrifuge, they
were kept at  -80 °C. Then TAS, TOS and OSİ
were studied by using Erel method. 

 ResultsTAS value was found as
1,0945±0,25, TOS value as 15,38±6,10 and OSi value was found as
1,4827±0,67.  TAS value of unventilated
patients was found as 1,1514±0,24, TOS value was as 25,73±9,25 and OSi value
was found as 2,2993±0,85. TOS value in patients increased in unventilated
patients. The increase in  TOS value in
our study did not form any change on TAS value however there occured a
significant difference on  OSİ value.
(p<0.05)

Conclusions: As two groups were
compared there did not occur a significant difference on TAS value, there came
out a significant result in terms of TOS and OSİ values. During CPB, TOS and
OSİ values of unventilated patients were found high and significant compared to
10% ventilated patients. This situation shows that oxidative stress parameters
in 10% ventilated patients decreases during CPB.
