PRACTICE OF PHYSIC. 



a danger may arise from too large a wound being made in the 

 vessels of the lungs ; from a quantity of red blood being left to 

 stagnate in the cavity of the bronchiae ; and particularly, from any 

 determination of the blood being made into the vessels of the 

 lungs, which, by renewing the haemorrhagy, may have danger- 

 ous consequences. In every instance therefore of haemoptysis, 

 the effusion is to be moderated by the' several means mentioned 

 (DCCXCII. to DCCXCV.). 



DCCCXLVII. These measures are especially necessary 

 when the haemoptysis arises in consequence of predisposition ; 

 and in all cases where there is the appearance of a large effu- 

 sion, or where the haemorrhagy frequently returns, the effusion 

 is not only to be moderated, but to be entirely stopped, and the 

 returns of it prevented by every means in our power. See 

 DCCXCVII. and following. 



DCCCXLVIII. To stop an haemoptysis, or prevent the 

 returns of it, two medicines have been frequently employed ; 

 neither of which I can approve of. These are, chalybeates, 

 and the Peruvian bark. As both of them contribute to increase 

 the phlogistic diathesis of the system, they can hardly be safe 

 in any case of active haemorrhagy, and I have frequently found 

 them hurtful. 



DCCCXLIX. As the haemoptysis which happens in con- 

 sequence of predisposition, is always attended with a phlogistic 

 diathesis ; and as the bad consequences of the disease are 

 especially to be apprehended from the continuance of that 

 diathesis ; so this is to be industriously taken off by blood- 

 letting, in greater or smaller quantity, and more or less fre- 

 quently repeated, according as the symptoms shall direct. At 

 the same time, cooling purgatives are to be employed, and 

 every part of the antiphlogistic regimen is to be strictly en- 

 joined. The refrigerants may also be administered ; taking 

 care, however, that the acids, and more especially the nitre, do 

 not excite coughing. 



DCCCL. From what was observed in DCCXCV. it will 

 appear, that blistering upon the breast or back may be a remedy 

 of haemoptysis, when it is present ; and that issues in the same 

 places may be useful in preventing the recurrence of it when it 

 has ceased.
