Occurrence regularity and risk factors of new-onset atrial fibrillation in early stage after brain and spinal surgery

Abstract

Objective To explore the occurrence regularity and risk factors of new-onset atrial fibrillation in early stage after brain and spinal surgery of Neurosurgery Department so as to provide a basis for carrying out predictive nursing for high-risk population. Methods From March to June 2019, we selected 107 patients with brain or spinal surgery of Neurosurgery Department at a Class Ⅲ Grade A hospital in Beijing by convenience sampling. Data were collected including electrocardiogram of patients 12 hours after surgery, general information and clinical data. We analyzed the incidence and characteristics of atrial fibrillation, hospital stay as well as incidences of complications. Logistic regression model was used to analyze the risk factors. Results A total of 107 patients were included. The incidences of new-onset atrial fibrillation in early stage after surgery and persistent atrial fibrillation were 16.80% (18/107) and 1.87% (2/107) respectively. The average onset time of new-onset atrial fibrillation after surgery was 261.00 (87.00, 419.00) min after surgery. The incidence (50.00%) of atrial fibrillation within 4 h after surgery was the highest, and decreased progressively after that. The average duration of atrial fibrillation every time was 3.00 (1.50, 8.30) min, and the total duration was 5.50 (3.00, 11.25) min. The risk factors of new-onset atrial fibrillation after surgery of Neurosurgery Department included the high levels of blood phosphate and lymphocyte percentage before surgery, lesion located in brainstem or insular lobe as well as a low level of fasting blood glucose after surgery (P<0.05) . Conclusions New-onset atrial fibrillation after brain and spinal surgery of Neurosurgery Department mostly occurred within 8h after surgery. Pay attention to heart rhythm after surgery of patients with high levels of blood phosphate and lymphocyte percentage before surgery, lesion located in brainstem or insular lobe as well as a low level of fasting blood glucose after surgery.
