Background and Goal of Study: The number of cardio surgical interventions in the world is increasing
every year, leading to a disability and a decrease in the quality of life [1,2]. The incidence of chronic
postoperative pain (CPOP) after thoracotomy and sternotomy is 5-65%, indicating severe pain in 10% of
all CPOP patients [3]. This study aims to analyze the incidence of CPOP in cardiac surgery.
Materials and Methods:107 case histories of patients, operated in Jan. 2015 – Jun. 2016, were
retrospectively analyzed. According to the surgery type, all the patients were divided into following
groups: bypass surgeries, aorta and cardiac valve replacements, Bentall procedures and combined
surgeries. We contacted the patients via phone calls in terms of ischemic/anginal pain in the surgical
approach area.
Results and Discussion:The majority of participants were men (79,4%). The mean age was 59,6
years. 37 (34,58%) respondents reported CPOP: 19 (37.25%) in the bypass group, 4 (26.7%) – with
aorta and cardiac valve replacement, 8 (33.3% ) – with Bentall procedures, 6 (35.3%) in the group of
combined operations. The patient's age, duration of hospitalization and surgery didn’t show any
statistical significance according to the Mann-Whitney criterion in the development of CPOP.
Conclusion(s):The incidence of CPOP in cardiac surgery is 34.58% that represents a coincidence with
the current world literature data. Considering the importance of CPOP prevention, future studies of its
predisposing factors are needed.
