Paralysis of the right hemidiaphragm after liver transplantation: diagnosis and management / 中华肝胆外科杂志

ABSTRACT

Objective To review our experience in the diagnosis and management of paralysis of the right hemidiaphragm after liver transplantation. Methods 60 adult patients received liver transplantation from February 2001 to March 2007 in Sun Yat-sen Memorial Hospital were retrospectively analyzed. The pathophysiologic changes, clinical progress, and management of serious respiratory complications caused by post-transplant paralysis of the right hemidiaphragm were studied. Results Among 60 patients, 40 developed postoperative respiratory complications, and 5 were due to paralysis of the right hemidiaphragm. The 5 patients presented with paradoxical respiration and the ventilator supporting times were 14, 16, 34, 45, and 60 days, respectively. Tracheostomy was performed in 4. These patients developed pneumonia in 5, atelectasis in 4, acute respiratory distress syndrome (ARDS) in 4, hepatopulmonary syndrome in 4, and pulmonay interstitial edema in 3. Among the 5 patients, 4 patients survived and 1 patient died of ARDS and multiple organs failure 31 days after the transplantation. Conclusions After liver transplantation, strict monitoring of the respiratory function and timely use of a respirator for patients with the paralysis of the hemidiaphragm is very important. For patients with suspicious hemidiaphragm paralysis, tracheostomy should be decisively performed.
