Insights
Fever occurred in 29.9% of patients after coronary artery bypass graft (CABG) surgery, with sternal infections being the most common cause. Antibiotic use before and after CABG was linked to febrile syndrome development.
Area of Science:
- Cardiology
- Infectious Diseases
- Surgical Outcomes
Background:
- Coronary artery bypass graft (CABG) is a prevalent surgery for coronary artery disease.
- Ensuring high survival rates and successful outcomes is crucial due to the surgery's expense and impact on quality of life.
Purpose of the Study:
- To evaluate the incidence of fever (febrile events) post-CABG.
- To identify causes of fever, including pneumonia, wound infection, bacteremia, urinary tract infection, and inflammatory responses without infection.
Main Methods:
- A descriptive-analytical study involving 107 patients who underwent CABG.
- Data collected included patient characteristics (age, sex, underlying diseases), surgery duration, and antibiotic consumption patterns.
- Analysis focused on febrile events and incidence of infectious syndromes.
Main Results:
- The overall frequency of febrile events after CABG was 29.9%.
- Sternal infections were identified as the most common cause of fever.
- A significant correlation was observed between preoperative and postoperative antibiotic administration and the occurrence of febrile syndrome.
Conclusions:
- Fever affects nearly one-third of patients following CABG surgery.
- Antibiotic management strategies before and after surgery appear to influence the development of postoperative fever.
- Further research into optimizing antibiotic protocols may help reduce febrile complications.
Background:
Nowadays, coronary artery bypass graft (CABG) is a frequent surgery in treatment of coronary artery disease. According to high expense of this surgery and its important role in patients' quality of life, high survival rate of patients and success of surgery are necessary. The aim of this study was the evaluation of fever incidence (febrile events) due to incidence of pneumonia, wound infection, bacteremia, urinary tract infection and inflammatory response without infection after CABG.
Methods:
In an intergrades descriptive-analytical study, 107 patients who underwent coronary artery bypass graft (CABG) were enrolled in the study. The patients then were examined by the febrile events and also their characteristics including age, sex, duration of surgery, underlying diseases, and frequency distribution of antibiotics consumptions in pre-surgical and postsurgical periods, and incidence of infectious syndromes.
Results:
Frequency distribution of febrile events after CABG was 29.9 percent. The most common administered antibiotic before the surgery was cephalothin (Keflin) and then, cefazolin. The most common administered antibiotic after the surgery was cephalothin (Keflin) and cephalexin (47.7%) and then, cephalothin-gentamicin-cephalexin (31.8%). The average age of patients without febrile syndrome was 60.53 years and in those with febrile syndrome was 59.31 years. In terms of gender, 74.8% of the patients were males. So that 32.5% of males and 22.2% of females had fever. The incidence time of fever in most cases was in the postoperative fourth day. In terms of underlying diseases, 13 percent of them had hypertension and hyperlipidemia, 14 percent had only hypertension, 11.2 percent had only hyperlipidemia and 6.5 percent had diabetes.
Conclusion:
This study showed that the prevalence of fever in patients undergoing CABG was 29.9 percent and the most common cause of fever was sternal infections. There was a significant correlation between administered antibiotics in preoperative and postoperative periods and febrile syndrome.
