The novel case report of a temporary arrhythmia that developed after a positional change in a patient under general anesthesia emphasizes the possibility of potentially lethal cardiac arrhythmias that may develop owing to caudal movement of the peripherally inserted central venous catheter ([CVC] PICC) tip when changing patient positions. We present a case of temporary arrhythmia that developed after a positional change in a 44-year-old female patient scheduled for laparoscopic adrenalectomy under general anesthesia. She had undergone preoperative insertion of a PICC using an electrocardiogram (ECG)-guided tip confirmation system (TCS).

Background: Non-response to cardiac resynchronization therapy (CRT) is an important issue in the treatment of heart failure with reduced ejection fraction (HFrEF) and non-left bundle branch block (LBBB). Electrocardiogram-gated myocardial perfusion single-photon emission computed tomography imaging (G-MPI SPECT) is typically used to assess left ventricular (LV) dyssynchrony. This study aimed to determine whether G-MPI parameters are associated with non-responsiveness to CRT.

Article Synopsis
  • * This study analyzed data from 224 PAF patients who underwent their first transcatheter RFA, focusing on the average heart rate (AHR) measured before the procedure and its potential impact on recurrence rates of AF post-surgery.
  • * Results indicated that higher preoperative AHR was associated with lower rates of AF recurrence after ablation, suggesting a significant inverse relationship between AHR and the risk of AF returning in patients with PAF.

Preoperative autonomic failure in neonates with critical congenital heart disease.

Electronic address:

Background: Neonates with critical congenital heart disease (cCHD) undergo a complicated transition to ex-utero life. However, continuous monitoring of autonomic tone using heart rate variability is currently lacking.

Materials And Methods: We retrieved continuous electrocardiograms from the time of admission or from 10 days prior to surgery for neonates with dextro-transposition of the great arteries (d-TGA) and hypoplastic left heart syndrome (HLHS).

Preoperative evaluation: Impact on early perioperative hemodynamic and respiratory complications.

BMC Anesthesiol

November 2024

Faculty of Medicine, Department of Anesthesiology and Reanimation, Samsun University, Samsun, Turkey.

Background: The impact of routine preoperative anesthesia evaluations on potential perioperative complications remains unclear. This study aimed to investigate the effect of preoperative evaluation on early perioperative hemodynamic and respiratory complications.

Methods: This prospective observational study analyzed data from patients aged 18 to 80 who underwent elective surgery between October 15, 2023, and February 15, 2024.
