Giriş: Obezitenin insanlık için iyi bilinen bir tehdit
unsuru olduğu kanıtlanmış bir gerçektir. Ancak yıllar içinde yapılan birtakım
araştırmalarda obezitenin belirli durumlarda koruyucu rolü olduğu gibi çelişik
durumlar gözlemlenmiştir. Bu çalışmada artmış beden kitle indeksi (BKİ)
değerleri ile koroner arter baypas greftleme (KABG) cerrahisi sonrası göğüs
tüpü drenajı arasındaki ilişkiyi ortaya koymayı amaçladık.

Hastalar ve Yöntem: Aralık 2015-Aralık 2016 tarihleri
arasında, izole KABG operasyonu geçirmiş 421 hastanın verileri retrospektif
olarak tarandı. BKİ değerleri, Amerikan Kalp Derneği ve Dünya Sağlık Örgütü
tarafından belirlenen alt sınıflara gruplandırıldı. Bu alt gruplar; zayıf (<
20 kg/m2), normal (20-25 kg/m2), fazla kilolu (25-30 kg/m2), obez (30-35 kg/m2)
ve morbid obez (> 35 kg/m2) olarak kabul edildi. Postoperatif göğüs tüpü drenaj
değeri KABG sonrası ilk 24 saatte ölçülen değer olarak kaydedildi.

Bulgular: Çalışmaya katılan ortalama hasta yaşı 61.6 ± 1.06
idi. Hasta popülasyonunun çoğunluğunu 251 (%59.6) hasta ile erkekler
oluşturmaktaydı. Hastalar önce kabaca obez (> 30 kg/m2) (n= 136) ve non-obez
(< 30 kg/m2) (n= 193) olmak üzere iki gruba ayrıldı. Obez olmayan grupta
postoperatif ortalama göğüs tüpü drenaj miktarı 630 ± 360 mL iken, obez hasta
grubunda 463 ± 303 mL bulundu. BKİ ile KABG sonrası göğüs tüpü drenajı
arasındaki ilişkinin analizi için bağımsız t-test kullanıldı. Test sonucunda
ortaya çıkan ilişki istatistiksel olarak anlamlı idi. Bunun üzerine ileri
analiz amaçlı olarak KABG sonrası göğüs tüpü drenajının beş farklı BKİ alt
grubu ile ilişkisini değerlendirmeye karar verdik. Bunun için varyans analizi
(ANOVA) yapıldı ve sonuçların istatistiksel olarak anlamlı olduğu görüldü.

Sonuç: BKİ ile KABG sonrası göğüs tüpü drenajı arasında
negatif bir korelasyon bulunmaktadır. BKİ’nin ileride planlanabilecek kanama
öngörü skorlarında kullanılabileceğini düşünmekteyiz.

Negative Correlation Between Body Mass Index and Chest Tube Out-put After Coronary Artery Bypass Graft Surgery

Öz

Introduction: The
obvious threat of obesity to human life is well-known, but some contradictory
outcomes have been encountered during previous medical research. Interestingly,
obesity was recognized as a protective factor for some specific obesity-related
situations. We aimed to correlate increased body mass index (BMI) and chest
tube out-put after coronary artery bypass grafting (CABG).

 

Patients and Methods:
We retrospectively collected data of 421 patients who underwent isolated CABG
surgery between dates of December 2015 and December 2016. Obtained BMI values
were grouped into: underweight (< 20 kg/m2 ), normal weight (20-25 kg/m2 ),
overweight (25-30 kg/m2 ), obese (30-35 kg/m2 ), and severely obese (> 35 kg/m2
) subclasses. The postoperative chest tube output volume corresponded drainage
at first 24 hours after the CABG surgery.

 

Results: The mean age
was 61.6 (± 1.06) years. Female to male ratio was found 40, 9/59, 6 (n=
170/251). The patient population was divided into 2 groups as BMI below and
above 30 kg/m2 to approximately evaluate the relation between BMI and chest
tube out-put. Overall, 193 patients were in the non-obese group, and 136
patients were in the obese group. The mean drainage amounts of non-obese and
obese groups were 630 ± 360 and 463 ± 303 mL, respectively. We ran independent
t-test to evaluate the relationship between BMI and chest tube out-put. It was
statistically significant. The relationship between drainage and five different
BMI subgroups was evaluated. Analysis of variance (ANOVA) showed statistically
significant chest tube output difference between the normal and obese groups as
well as the severely obese group.

 

Conclusion: BMI is
negatively correlated with bleeding after CABG surgery and should be considered
in future bleeding prediction systems.
