Abstract

Amaç: Bu çalışmamızda preoperatif serum
sodyum değeri ile postoperatif klinik durum arasındaki ilişkiyi saptamayı ve
hiponatremik hastaların operasyon sonrasında sol ventrikül ejeksiyon
fraksiyonundaki artışın normonatremik olgularla karşılaştırmayı amaçladık.

Gereç ve Yöntem: Şubat 2014 – 2015 tarihleri arasında
kliniğimize başvuran ve açık kalp cerrahisi operasyonu olan, transplantasyon,
yapay kalp implantasyonu yapılan olgular ve hemodiyaliz gerektiren kronik
böbrek yetmezlik olguları dışındaki tüm hastalar çalışmamıza dahil edildi.
Hastalar kan serum sodyum değerlerine göre operasyon öncesi iki gruba ayrıldı.
Demografik veriler, entübasyon süreleri, yoğun bakım süreleri, inotrop
kullanımı, oluşan komplikasyonlar, sol ventrikül ejeksiyon fraksiyonu değişimi,
intraaortik balon pompası kullanımı, kardiyopulmoner baypas süreleri, kross
klemp süreleri ve klinik sonuçlar arasındaki fark değerlendirildi.



Bulgular: Hiponatreminin
postoperatif EF de
ğişimi üzerine etkisi saptanmamıştır. Olguların serum sodyum değerine göre
NYHA sınıflaması karşılaştırıldığında olguların hiponatremik hastalarda yüksek
NYHA sınıfında olma arasında anlamlı fark saptanmıştır. Hiponatremik grupta
postoperatif dönemde entübasyon süreleri, kullanılan kan ürünü ve postop drenaj
miktarı anlamlı derecede fazladır. Hiponatremik hastalarda postoperatif akut
böbrek yetmezliği görülme sıkılığı artmıştır. Hiponatremik hastalarda
postoperatif mortalite oranları anlamlı derecede yüksektir.   



Sonuç: Çalışmamızda preoperatif
hiponatreminin, kalp cerrahisi hastalarında prognostik önemi olduğunu
düşünmekteyiz.

The effects of preoperative hyponatremia on left ventricular ejection fraction and relation with clinical outcomes

Year 2019, Volume: 58 Issue: 3, 251 - 256, 20.09.2019

Abstract

Aim: In this study, we aim to investigate the relation between preoperative
serum sodium levels and postoperative clinical follow-up; moreover, to compare
the left ventricular ejection fraction increment in hyponatremic and
normonatremic cases. Herein, we present one-year results of our clinic in open
cardiac surgery performed patients.

Materials and Methods:
This is a retrospective study of cases who
underwent open cardiac surgery between February 2014-2015 in our clinic. Transplantation
assist device implanted cases and hemodialysis receiving patients by reason of
chronic renal failure were excluded.

Patients were divided into two groups according to blood serum sodium
levels on admission day as normonatremic (135–145 mEq/L) or hyponatremic
<135 mEq/L. The demographic characteristics of the patients, duration of
intubation and length of intensive care unit (ICU) stay, need for inotropic
support, mediastinal drainage amount, alteration in left ventricular ejection
fraction (LVEF), intraaortic balloon pump (IABP) usage ratio, occurrence of
acute renal failure, cardiopulmonary bypass time, cross clamping time and
differences in clinical outcomes were examined.

Results: Hyponatremia was observed in 31,3% of patients and those had higher NYHA
classification score. There was no statistical difference between groups in
LVEF alteration was determined (p=0.756). Postoperative duration of intubation
(p=0.003), need of blood products transfusion(p=0.033), vasoactive inotropic
support (p=0.021) and postoperative amount of drainage was statistically higher
in hyponatremic cases surplus(p=0.018). Peroperatively, both aortic cross
clamping time (p=0.018) and cardiopulmonary bypass durations (p=0.026) were
higher in hyponatremic group. Furthermore, postoperative mortality was also
significantly higher (p=0.001).









Conclusion: We suggest that being hyponatremic has a prognostic importance in
patients who undergo open cardiac surgery.
