What this trial studies

This clinical trial investigates the effectiveness of ketamine and tramadol in preventing post-spinal anesthesia shivering in patients undergoing elective cesarean sections. The study aims to reduce discomfort and anxiety associated with shivering by utilizing these medications, which work by blocking nerve signals and affecting temperature regulation in the brain. Participants will receive either ketamine or tramadol to assess their impact on shivering response and overall patient satisfaction during recovery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 18 to 40 years undergoing elective cesarean sections with an ASA classification of 1 or 2.

Not a fit: Patients requiring general anesthesia for their cesarean section or those with a history of cardiovascular disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance patient comfort and satisfaction during recovery from spinal anesthesia.

How similar studies have performed: While the use of ketamine and tramadol for shivering prevention is a novel approach, similar studies have shown promising results in managing post-anesthesia complications.
