Purpose: This study aimed to analyze the risk factors influencing intraoperative hypothermia in patients undergoing breast cancer surgery. Methods: Data were collected from 129 patients who underwent breast cancer surgery at a general hospital in City B from May 7 to November 14, 2024. The collected data were analyzed using SPSS/WIN 27 with an independent t-test, a χ 2 test ( χ 2 -test), and logistic regression analysis. Results: A total of 61 (47.3%) out of 129 patients experienced intraoperative hypothermia. According to the results of the logistic regression analysis, lower BMI (odds ratio [OR]=0.85, CI=0.74~0.98, p=.028), a total amount of IV fluid of ≥500 mL (odds ratio [OR]=4.47,CI=1.07~18.75, p=.041), a surgery duration of ≥120 minutes (odds ratio [OR]=4.10, CI=1.02~16.51, p=.047), and intraoperative hypotension (odds ratio [OR]=3.64, CI=1.22~10.86, p=.020) were associated with an increased risk of intraoperative hypothermia. Conclusion To prevent intraoperative hypothermia, continuous observation and nursing intervention are required for patients with low BMI or those expected to undergo prolonged surgery. The use of warm fluids during surgery and proper intraoperative blood pressure management is also recommended.

BACKGROUND AND OBJECTIVES: Although an anterior linear ablation is an effective lesion set in radiofrequency catheter ablation (RFCA) for longstanding persistent atrial fibrillation (L-PeAF), its durability for bidirectional block (BDB) is only about 60% at repeat procedure. We hypothesized that changes in electrocardiogram (ECG) may predict an anterior line block state and the clinical outcome of L-PeAF ablation. SUBJECTS AND METHODS: We studied 304 L-PeAF patients (77% male, 60±10yrs), who consistently underwent RFCA Dallas lesion set (circumferential pulmonary vein isolation, posterior box lesion, and anterior line) protocol with subsequent comparison of pre-procedural and post-procedural P wave axes, and one year follow-up (n=205) sinus rhythm (SR) ECGs. RESULTS: 1. P wave axis shifted inferiorly at immediate post-procedure (p<0.001), and was independently correlated with BDB of anterior line (β=10.4, 95% confidence interval [CI] 2.79-17.94, p=0.008). 2. The degree of post-procedural inferior shift of P wave axis did not reflect clinical recurrence within one-year (n=205, p=0.923), potentially due to conduction recovery of an anterior line. However, among 160 patients without clinical recurrence within one-year, P wave axis at one-year ECG was independently associated with very late recurrence of AF after one-year (n=160, hazard ratio [HR] 0.98; 95% CI 0.97-0.99, p=0.001), during 45.6±16.7 months of follow-up. 3. Among 22 patients who underwent repeat procedures, P wave axis shift was more significant in patients with maintained BDB of an anterior line than in those without (p=0.015). CONCLUSION: An inferior shift of P wave axis reflects the achievement and the maintenance of an anterior line BDB, and is associated with better long-term clinical outcome after catheter ablation for L-PeAF based on Dallas lesion set.

PURPOSE: The purpose of this study was to investigate the extent and the nature of biological nursing science education for clinical nurses in general hospital. METHODS: Five advanced general hospitals located in Seoul and Gyeonggi province were conveniently sampled. Contents of education for nurses conducted by the hospital nursing department from January 1 to December 31 of 2015 were collected. Contents of education included biological nursing science and the scope of inclusion and time of assignment were analyzed. RESULTS: A total of 271 cases of nursing education data were collected and 223 cases were analyzed after excluding 48 cases whose contents were not confirmed. Biological nursing science was included in the contents of education for 117 cases (52.5%), but not for 106 cases (47.5%). Regarding the frequency of the biological nursing science education contents, ‘pathophysiology’was the most frequently included (n=286), followed by ‘structure and function of the human body’ (n=191), ‘mechanisms and effects of drugs’ (n=114) and ‘clinical microbiology’ (n=43). CONCLUSION: Results of this study confirmed that the education for clinical nurses included a lot of biological nursing science related contents. These results can be used as basis for the development of curriculum and training course for nurses.

PURPOSE: Electric cardioversion has been successfully used in terminating symptomatic atrial fibrillation (AF). Nevertheless, largescale study about the acute cardiovascular events following electrical cardioversion of AF is lacking. This study was performed to evaluate the incidence, risk factors, and clinical consequences of acute cardiovascular events following electrical cardioversion of AF. MATERIALS AND METHODS: The study enrolled 1100 AF patients (mean age 60+/-11 years) who received cardioversion at four tertiary hospitals. Hospitalizations for stroke/transient ischemic attack, major bleedings, and arrhythmic events during 30 days post electric cardioversion were assessed. RESULTS: The mean duration of anticoagulation before cardioversion was 95.8+/-51.6 days. The mean International Normalized Ratio at the time of cardioversion was 2.4+/-0.9. The antiarrhythmic drugs at the time of cardioversion were class I (45%), amiodarone (40%), beta-blocker (53%), calcium-channel blocker (21%), and other medication (11%). The success rate of terminating AF via cardioversion was 87% (n=947). Following cardioversion, 5 strokes and 5 major bleedings occurred. The history of stroke/transient ischemic attack (OR 6.23, 95% CI 1.69-22.90) and heart failure (OR 6.40, 95% CI 1.77-23.14) were among predictors of thromboembolic or bleeding events. Eight patients were hospitalized for bradyarrhythmia. These patients were more likely to have had a lower heart rate prior to the procedure (p=0.045). Consequently, 3 of these patients were implanted with a permanent pacemaker. CONCLUSION: Cardioversion appears as a safe procedure with a reasonably acceptable cardiovascular event rate. However, to prevent the cardiovascular events, several risk factors should be considered before cardioversion.
