Mobitz II Second-Degree Heart Block During Total Hip Arthroplasty: ACase Report

Area of Science:

• Anesthesiology
• Cardiology
• Perioperative Medicine

Background:

• Mobitz II second-degree atrioventricular block is a rare intraoperative complication.
• Effective management is crucial due to its potentially fatal nature.
• Limited literature exists on perioperative management strategies for this arrhythmia.

Observation:

• An elderly patient without prior conduction abnormalities developed spontaneous Mobitz II second-degree atrioventricular block during total hip arthroplasty.
• The complication occurred unexpectedly during the surgical procedure.
• The patient had no preceding history of cardiac conduction issues.

Findings:

• Successful perioperative management of Mobitz II second-degree atrioventricular block was achieved, preventing morbidity and mortality.
• A practical management algorithm for this specific clinical scenario was developed.
• The case highlights the importance of prompt recognition and intervention.

Implications:

• The proposed algorithm serves as a valuable guide for anesthesiologists and anesthetists in managing similar critical situations.
• This case report contributes to the limited body of literature on intraoperative atrioventricular block.
• The findings can aid in the education and training of medical professionals dealing with cardiac arrhythmias during surgery.
