ABSTRACT
BACKGROUND: Supraventricular cardiac arrhythmias are the most common rhythm disturbances in patients following thoracic surgery. The purpose of our study was to determine which of the clinical parameters are the most valuable in predicting postoperative atrial fibrillation (AF) after lung surgery. METHODS: Retrospective analysis was carried out on 987 patients after noncardiac thoracic surgery to define the prevalence, associated risk factors, and clinical course of postoperative arrhythmias. There were 822 men and 165 women, age 34 to 78 years (mean age: 61 ± 8 years). The patients were divided into two groups depending on the occurrence or absence of supraventricular arrhythmia. Group I consisted of 876 patients who were free from rhythm disturbances. The remaining 111 patients exhibited episodes of supraventricular arrhythmia (29 supraventricular tachycardia; 82 AF). These 111 patients were placed in Group II. Preoperative, operative, and postoperative data were reviewed. Statistical analysis was performed. RESULTS: A statistically significant difference was found between the two groups in age, previous history of heart disease, and lung resection, especially pneumonectomy. CONCLUSION: Age, history of prior heart disease, lung resection, and the extent of pulmonary resection are the main risk factors for postoperative supraventricular arrhythmia in patients undergoing major thoracic operations.

OBJECTIVE: To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality. METHODS: This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations. The study took place at Al-Hada Military Hospital, Taif, Kingdom of Saudi between May 2008 and January 2012. Data were statistically analyzed using Chi square (x2) test and multivariable logistic regression, to evaluate the postoperative morbidity and mortality risks associated with low serum creatinine levels. RESULTS: Postoperative mortality increased with high serum creatinine level >1.8 mg/dL (p
