Impact of spinal anesthesia on heart electrical activity in pregnant women undergoing cesarean sections

Comparison of the Effect of Spinal Anesthesia Applied in Elective Cesarean Cases on Frontal QRS Angle in Anemic and Non-Anemic Patients

Observational Sanliurfa Mehmet Akif Inan Education and Research Hospital · NCT06434870

This study is testing how spinal anesthesia affects heart electrical activity in pregnant women having cesarean sections, especially looking at those who are anemic and those who are not.

What this trial studies

This observational study investigates the effect of spinal anesthesia on the frontal QRS-T angle, a marker of myocardial repolarization, in both anemic and non-anemic patients undergoing elective cesarean sections. The study aims to assess how spinal anesthesia influences cardiac electrical stability during this common surgical procedure. By utilizing 12-lead electrocardiography, researchers will measure the QRS-T angle to evaluate potential arrhythmia risks associated with anesthesia in pregnant patients. The findings could provide insights into the cardiovascular implications of anesthesia methods in this population.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women aged 18-45 years with an ASA II classification who are scheduled for elective cesarean sections.

Not a fit: Patients with existing rhythm disorders, electrolyte disturbances, liver or renal failure, obesity, trauma, cancer, or those classified as ASA III-IV will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety of anesthesia practices during cesarean sections, potentially reducing the risk of arrhythmias in pregnant patients.

How similar studies have performed: While the specific approach of this study may be novel, previous studies have indicated the importance of monitoring cardiac stability during anesthesia in pregnant patients, suggesting potential for meaningful insights.
