Koroner Arter Bypass Grefti Cerrahisine Giden Diyabetik Hastalarda Preoperatif Sigara Kullanılmasının Postoperatif Serebrovasküler Olaylar Üzerine Etkisi

Year 2011, Yıl: 2011 Sayı: 3, 97 - 102, 01.11.2011

Abstract

AMAÇ: Bu çalıșma koroner arter bypass cerrahisi (KABC) uygulanan
diyabetik hastalarda gelișebilecek postoperatif serebrovaskü-
ler olay (SVO) ile preoperatif sigara içiminin ilișkisini araștırmak için
düzenlenmiștir.
YÖNTEM: Bu prospektif çalıșmada Ocak 2008 ve Temmuz 2011
tarihleri arasında KABC geçiren 135 hasta yer aldı. Hastalar iki gruba
ayrıldılar. Grup 1 sigara içenler (n=17), Grup 2 ise sigara içmeyenlerden
olușuyordu (n=118). Postoperatif öngörülen SVO riski
için Amerikan Kalp Derneği’nin 2004’de güncellediği ölçüt kullanıldı.
Kriterlere göre tahmini postoperatif SVO riski %0,6 ile %2 (bü-
tün hastalar için ortalama %1,04±0,4) arasında değiști. Bütün hastalar
postoperatif olası SVO’yu tanıyabilmek için ameliyat sonrası
60 günlük takip programına alındılar. SVO açısından belirti, bulgu
ya da șüphesi olan hastalar; radyoloji ve nöroloji bölümleri ile ișbirliği
altında multi-disipliner yaklașım ve seri kraniyal tomografilerle
değerlendirildiler. İstatistiksel analiz Student t, Fischer’in kesinlik,
Yates’in düzeltmeli ki-kare testi ve Mann Whitney U testleri kullanılarak
yapıldı. P değerinin 0,05’ten küçük olması anlamlı sayıldı.
BULGULAR: Katılımcıların 83’ü erkek ve 52’si kadındı. Hem sigara
içenlerin (%88,2) hem de içmeyenlerin (%57,6) grubunda erkekler kadınlara
göre anlamlı derecede daha fazlaydılar (p< 0,05). Sigara içenler
grubundaki erkek oranı, sigara içmeyenler grubundaki erkek oranından
da anlamlı derecede fazlaydı (p< 0,05). İnsüline bağımlı DM oranı
sigara içenler grubunda %52,9 ve içmeyenler grubunda %30,5’ti,
ancak iki grup arası fark istatistiksel olarak anlamalı değildi (p> 0,05).
Preoperatif olarak belirlenen tahmini postoperatif SVO oranı, intraoperatif
pompa ve çapraz klampleme zamanları açısından gruplar
arası anlamlı farklılık saptanmadı (p>0,05). Sigara içenler grubunda
iki (%11,8) ve içmeyenler grubunda iki (%1,7) postoperatif SVO gö-
rüldü. Postoperatif SVO oranı sigara içenlerde anlamlı derecede
yüksekti (p< 0,05).
SONUÇ: KABC için kardiyovasküler cerrahi bölümüne bașvurudan
önceki son altı ayda sigara içmek, diyabetik hastalarda postoperatif
SVO riskini arttırır.

The Effect of Preoperative Smoking on Postoperative Cerebrovascular Accidents in Diabetic Patients Undergoing to Coronary Artery Bypass Graft Surgery

Abstract

AIM: The study was designed to investigate the correlation between
preoperative cigarette smoking and postoperative cerebrovascular
accidents (CVA) after coronary artery bypass graft (CABG)
surgery in diabetic patients.
METHODS: This prospective observational study included 135 diabetic
patients underwent coronary artery bypass graft surgery between
January 2008 and August 2011. The participating patients
were divided into two groups as: Group 1 (n=17) smokers and Group
2 (n=118) non-smokers. Preoperative risk analysis for estimating the
post operative CVA was performed by using the criteria of American
Heart Association (ACC/AHA) updated in 2004. According to the
criteria, assumed postoperative CVA risks ranged between 0.6%
and 2% (mean rate for all patients was 1.04±0.4%). Until the
postoperative 60th day, all patients were integrated in a follow up
programme to scan and diagnose a probable CVA. Patients with
symptoms, signs and suspicions of CVA were evaluated by a series
cranial tomography scanning and a multi-disciplinary approach
in conjunction with the departments of radiology and neurology.
Statistical analysis was performed using Student’s t test, Fischer’s
exact test, Yates’ correction chi-square test and Mann-Whitney U
test. A p value < 0.05 was considered statistically signifi cant.
RESULTS: There were 83 male and 52 female participants. The
number of males was signifi cantly higher than the females in
both the smokers (88.2%) and the non-smokers groups (57.6%),
(p< 0.05). The rate of the male patients in the smokers group was
also signifi cantly higher than the rate of the smokers in the nonsmokers
group (p< 0.05). The rate of patients with insulin dependent
DM was 52.9% and 30.5% in the smokers and non-smokers
group, respectively, however the inter group difference was not
signifi cant (p> 0.05). The rate of preoperatively defi ned estimated
postoperative CVA risk, intra-operative pump use and crossclamping
durations did not show signifi cant differences between
the smokers and non-smokers (p> 0.05). There were two postoperative
CVA (11.8%) cases in the smokers and two CVA cases in
the non-smokers (1.7%) groups. The rate of CVA was signifi cantly
higher among the smokers in comparison with the non-smokers
(p< 0.05).
CONCLUSION: Smoking in the last six months before attending
to the department of cardiovascular surgery for isolated CABG
surgery increases the risk for post operative CVA in diabetic
patients.
