Wounds. 



Simple Operative Wounds-The hair should be shaven from the 

 surrounding area. The skin should be washed with green soap and 

 water, with 50 per cent, alcohol and finally with pure ether or, better, 

 Harrington's solution, 216. The operator's hands should be 

 cleansed likewise and covered with rubber gloves. The wound 

 should be handled as little as may be. All hemorrhage must be 

 arrested. If the wound is deep, it should be closed by layers of 

 buried catgut sutures, the skin by silk-worm gut sutures (inter- 

 rupted). Drainage should be avoided unless the conditions are very 

 unfavorable. Cover the wound with dry aseptic gauze and band- 

 age. Secure rest by splints if possible. Leave dressings in place 

 for a week or two, unless they become soiled and displaced. 



Accidental Wounds— If the wound is fresh, arrest hemorrhage 

 by hot (or even boiling) water; ice water; actual cautery, in very 

 vascular or deep seated parts, using a dull-red heat; rubber tourni- 

 quet; acupressure; pressure by fingers or hemostatic forceps; tor- 

 sion; or chemicals — as adrenalin solution. Long and continuous 

 cleansing of the wound with corrosive solution (1-5,000), lysol or 

 creolin (2 per cent.), and swabbing the wound with pure hydrogen 

 dioxide, are essential to remove macroscopic and microscopic for- 

 eign matter and germs. The skin surrounding the wound should 

 first be treated as for operative wounds (see above). Divided struc- 

 tures, as tendons, nerves and muscles, should be sutured with sterile 

 catgut (as St. John Leavens). If the surroundings are favorable 

 and the wound can be bandaged, it should be closed as an opera- 

 tive wound without drainage. If the wound is deep, and the con- 

 ditions unfavorable, drainage by a sterile rubber tube placed into 

 the deeper parts of the wound, and the rest of the wound sutured 

 — should be the rule. It is always easy to reopen a wound and re- 

 move sutures, if infection occurs, but to secure a first intention is 

 impossible when the wound has become generally infected. The 

 first dressing should always be retained as long as possible to avert 

 infection.
