BACKGROUND
In patients with severe chronic lung diseases even a small pneumothorax can result in life-threatening respiratory distress. It is important to treat the attack by chest tube drainage until the lung expands. Pneumothorax with a persistent air leak that does not resolve under prolonged tube thoracostomy suction is usually treated by open operation to excise or oversew a bulla or cluster of blebs to stop the air leak. Pleurodesis by the instillation of chemical agents is used for the patient who has persistent air leak and is not good candidate for surgical treatment. When the primary trial of pleurodesis with common agent fails, it is uncertain which agent should be used f or stopping the air leak by pleurodesis. It is well known tbat inappropriate drainage of hemothorax results in severe pleural adhesion and thickening. Based on this idea, some reports described a successful treatment with autologous blood instillation for pneumothorax patients with or without residual pleural space. We tried pleurodesis with autologous blood for pneumothorax with persistent air leak and then we evaluated the efficacy and safety. METHODS: Fifteen patients who had persistent air leak in the pneumothorax complicated from the severe chronic lung disease were enrolled. They were not good candidates for surgical treatment and doxycycline pleurodesis failed to stop up their air leaks. We used a mixture of autologous blood and 50% dextrose for pleurodesis. Effect and complications were assessed by clinical outcome, chest radiography and pulmonary function tests. RESULTS: The mean duration of air leak was 18.4 :1:6.16 days before ABP (autologous blood and dextrose pleurodesis) and 5.2 ± 1.68 days after ABP, The mean severity of pain was 2.3 ± 0.70 for DP(doxycycline pleurodesis) and 1.7 ± 0.59 for ABDP (p<0.05). There was no other complication except mild fever. Pleural adhesion grade was a mean of 0.6 ± 0.63. The mean dyspnea scale was 1.7 ± 0.46 before pneumothrax and 2.0 ± 0.59 after ABDP (p>0.05). The mean FEV1 was 1.47 ± 1.01 before pneumothorax and 1.44 ± 1.00 after ABDP (p>0.05). Exɡpt in 1 patient, 14 patients had no recurrent pneumothorax. CONCLUSION: Autologous blood pleurodesis (ABP) was successful for treatment of persistent air leak in the pneumothorax. It was easy and inexpensive and involved less pain than doxycycline pleurodesis. It did not cause complications and severe pleural adhesion. We report that ABP can be considered as a useful treatment for persistent air leak in the pneumothorax complicated from the severe chronic lung disease. |
