tSEUDO-PERICARDlTlS. S93 



Prognosis. Although grave, the prognosis is less so than in true 

 pericarditis. 



Treatment. If clearly recognised, both suhpleural and subperi- 

 cardial abscesses seem cm-able. By freely puncturing the pus-filled 

 cavity through an intercostal space, the liquid may be evacuated and 

 recovery may occur. Healing is favoured by carefully washing out the 

 cavity with a non-irritant disinfectant. 



The only precaution required in making such punctures is to avoid 

 the internal thoracic artery and vein, the intercostal artery, and the 

 lower cul-de-sac of the pleura.
