AbstractOne hundred and one (6%) of 1,678 patient studied had bilateral reexpansion pulmonary oedema(RPO). On the whole, one thousand, seven hundred and seventy nine (1,779) pleural spaces were studied, fifteen pleural spaces (0.8%), with mean age of 23 +/- 4.5 years had RPO. Among these 15 patients with RPO, the mean period of lung collapse before pneumothorax (PThx) was evacuated was 31.8 +/- 21.8 days and for hydrothorax (HThx) was 31.3 +/- 30.1 days; for 15 patients without RPO (controls), matched for age and sex, the mean period of lung collapse before CTTD was 7.5 +/- 4.1 days and 5.4 +/- 1.3 days respectively for PThx and HThx. The differences in the period of lung collapse among patients with RPO and those without, for each pleural disease was statistically significant (P < 0.03). Volume of pleural fluid drained before RPO was noticed was 2196 +/- 1103 mls, for the 15 matched patients without RPO (controls), it was 1060 +/- 115 mls (p < 0.05). Volume of pleural fluid drained among the patients with SR (Severe response), MR (mild to moderate response) and RD (radiological diagnosis) did not correlate with severity of response. We conclude that prevention of RPO is the desired goal in the management of pleural effusion or Pneumothorax. RPO is commonest among young patients who have had lung collapse for 7 or more days. In these circumstances RPO is prevented, its incidence and severity reduced by methods of gradual evacuation of PThx or pleural fluid drainage.
