Background: Although cardiac surgery has been
improved in both surgical and anesthesia technique. It is
still categorized as the major surgery with high risk for
postoperative complications. Suratthani Hospital has
performed open heart surgery for many years but still lacks
data on postoperative complications.
Objectives: To explore the postoperative complications
after open heart surgery at Suratthani Hospital and identify
risk factors.
Methods: The electronic database of the hospital between
October 2017 and September 2018 were reviewed
retrospectively. The collected data were preoperative
status, intraoperative events and postoperative major
Results: One hundred and forty patients were enrolled.
The overall postoperative complication was 68.6%. They
were categorized as: cardiovascular system 54.3%;
respiratory system 29.3%; neurological system 1.4%;
renal system 25.7%; infection 5%; and reoperation 7.9%.
The mortality rate was 7.9%. The risk factors for postoperative
complications were preoperative hypertension (OR 2.896,
95%CI 1.386-6.052, p=0.004) and arrhythmia (OR 3.151,
95%CI 1.018-9.750, p=0.041), cardiopulmonary bypass
time >150 min (OR 3.476, 95%CI 1.515-7.975, p=0.003),
and aortic cross-clamping time >90 min (OR 3.516, 95%CI
1.437-8.600, p=0.005)
Conclusions: The incidence of postoperative complications
in open heart surgery was 68.6% with mortality rate of
7.9%. The identified risk factors were preoperative

hypertension, arrhythmia, cardiopulmonary bypass time
>150 min and aortic cross-clamping time >90 min.
