An Easy Method of Draining Inaccessible Suppurating Cavities

Fit the nozzle of a 4 oz. or 8 oz. glass syringe into a Jacques' catheter of the required size and charge the catheter and the syringe with weak iodine solution. Introduce the catheter into the bottom of the cavity to be drained. Inject the solution slowly into it and draw the contents of the cavity into the syringe. Take the syringe out, leaving the catheter still in the cavity, and throw out its contents into a bucket close by. Charge it again with the iodine solution and refit the syringe into the catheter now in the cavity and draw out its contents again into the syringe and throw them out into the 'bucket. Repeat the process 6 to 8 times until the contents drawn from the cavity are nearly of the same colour
