Good functional outcome following open‐chest cardiopulmonary resuscitation in a dog with pleural space disease

A 5‐year‐old neutered male German Hound was referred for management of pyothorax. After needle thoracocentesis and intubation for a computed tomography scan, a paraesophageal abscess and lung consolidation were identified. The dog experienced cardiopulmonary arrest (CPA), likely from tension pneumothorax. Sinus bradycardia led to asystole within 60 s. Open‐chest cardiopulmonary resuscitation (OCCPR) was immediately performed through a right‐sided thoracotomy, with direct cardiac compressions, manual ventilation and administration of atropine and adrenaline per RECOVER guidelines. Spontaneous circulation returned within 6 min. The paraesophageal abscess was addressed surgically through a sternotomy, with lavage of the thoracic cavity, chest tube placement and closure of both thoracic entry points. Postoperative care included oxygen therapies, transfusions and fluids. The dog was discharged 6 days post‐CPA and remained healthy 6 months later. This case indicates that OCCPR can be effective for CPA in dogs with pleural space disease when performed via a right‐sided thoracotomy, in conjunction with intensive post‐arrest care.
