AI Article Synopsis
- Atrial fibrillation (AF) is a common heart rhythm issue that can be difficult to control during surgery using standard treatments.
- Two case studies are presented where dexmedetomidine, a medication typically used for sedation, successfully stabilized heart rates in AF patients when other options failed.
- This suggests dexmedetomidine may have untapped potential for managing AF during surgeries, highlighting the need for further research on its use and proper dosing in such scenarios.
Article Abstract
Atrial fibrillation (AF) is a common arrhythmia requiring effective heart rate (HR) management. Conventional therapies may not always achieve the desired HR control during intraoperative conditions. We present two cases of AF patients in whom dexmedetomidine, an alpha-2 receptor agonist, was utilized during surgery when conventional treatments proved ineffective. In Case 1, a 65-year-old male with multiple comorbidities underwent surgery. Despite receiving intraoperative medications for AF, his HR remained uncontrolled. Dexmedetomidine successfully stabilized his HR without complications. In Case 2, a 75-year-old male with heart disease experienced a sudden HR surge during surgery, which remained uncontrolled despite conventional treatment. Dexmedetomidine effectively managed his HR, ensuring a safer surgical course. While the primary indication of dexmedetomidine is not arrhythmia management, this case report suggests its potential in challenging cases. Further research is needed to explore its therapeutic role in tachyarrhythmia management and establish appropriate dosing strategies.

Preterm births constitute a major public health issue and a chronic, cross-generational condition globally. Psychological and biological factors interact in a way that women from low socio-economic status (SES) are disproportionally affected by preterm delivery and at increased risk for the development of perinatal mental health problems. Low SES constitutes one of the most evident contributors to poor neurodevelopment of preterm infants.

Background: Motor imagery is the mental representation of a movement without physical execution. When motor imagery is performed to enhance motor learning and performance, participants must reach a temporal congruence between the imagined and actual movement execution. Identifying factors that can influence this capacity could enhance the effectiveness of motor imagery programs.

Previous studies have provided relatively limited evidence in examining the impact of preoperative serum albumin levels on the length of hospital stay (LOS) in patients with hip fractures. This study aimed to elucidate the association between preoperative serum albumin levels and LOS in elderly patients with hip fractures. This retrospective cohort study included 1444 elderly patients undergoing surgical treatment for hip fractures at the Second People's Hospital of Shenzhen from January 2012 to December 2021.

Understanding the differences between children with severe and non-severe types of neonatal pneumonia is crucial for clinical treatment and disease management. In this study, we retrospectively analyzed the clinical data of infants with neonatal pneumonia diagnosed as respiratory syncytial virus infection at Wuhan Children's Hospital between December 1, 2022 and November 30, 2023. Further, the recruited subjects were categorized into severe and non-severe groups based on the severity score.
