BACKGROUND:
Surgery in patients affected by amyotrophic lateral sclerosis (ALS) presents a particular anesthetic challenge because of the risk of post-operative pulmonary complications.
AIMS OF THE STUDY:
We report on the use of non-invasive ventilation (NIV) to prevent post-operative pulmonary complications (PPCs) in nine patients affected by ALS enrolled in a phase-1 clinical trial with stem cell transplantation.
METHODS:
All patients were treated with autologous mesenchymal stem cells implanted into the spinal cord with a surgical procedure. Anesthesia was induced with propofol and maintained with remifentanil and sevoflurane. No muscle relaxant was used. After awakening and regain of spontaneous breathing, patients were tracheally extubated. Non-invasive ventilation through nasal mask was delivered and non-invasive positive pressure ventilation and continuous positive pressure ventilation were started.
RESULTS:
The average time on NIV after surgery was 3 h and 12 min. All patients regained stable spontaneous breathing after NIV discontinuation and had no episodes of respiratory failure until the following day.
CONCLUSIONS:
Our case series suggest that the use of NIV after surgery can be a safe strategy to prevent PPCs in patients affected by ALS. The perioperative procedure we chose for these patients appeared safe even in patients with advanced functional stage of the disease.
