Abstract

Introduction: Thoracic surgery is a specialty with specific anesthetic management requirements. This is a recent specialty in Togo, with a multi-skilled anesthetic team.


Aim: To describe the anesthetic management and morbidity of thoracic surgery.


Methods: A descriptive, prospective and observational study was conducted on a cohort of patients who underwent a thoracic surgery between June 1 and August 31, 2022, at the national referral hospital in Lomé. The study examined pre-anesthetic assessment, surgical, anesthetic, and postoperative data.


Results: Twenty-five patients with a mean age of 40 ±13 years were included. The surgery was elective in 69% of cases. The anesthetic assessment showed anemia (64%) and a reduced forced expiratory volume in one second (60%)


All patients were operated on under general anesthesia with controlled ventilation, including 64% of one-lung ventilation. Surgical procedures included pleural decortication (28%), pericardial drainage (16%), pneumonectomy (16%), and pulmonary lobectomy (12%).  Twenty-three patients (92%) experienced intraoperative complications, including arterial hypotension (80%), shock (56%), and hypoxia (24%).


Multimodal analgesia including paracetamol (100%), nefopam (92%), morphine (76%), paravertebral analgesia (20%), and thoracic epidural analgesia (8%), was used postoperatively.


Seventeen patients (68%) experienced postoperative complications, including anemia (20%), pneumonia (12%), and parietal infection (12%). Three patients (12%) died.


Conclusion: General anesthesia with, one-lung ventilation in most cases, was the anesthetic technique in thoracic surgery. Complications, mainly cardiovascular, occurred intraoperatively, with high postoperative mortality.
