It has been claimed that syncope is liable to occur from too CHLOROFORM I4I marked intermittance in the administration. Incomplete anaes-thesia appears to be associated with complications of all de-grees of severity, much more so under chloroform than underether. Vomiting, which is often an evidence of incomplete chlo-roform anaesthesia, may be the starting point of other compli-cations of both the respiration and circulation. It is very important that the requisite degree of anaesthesiashould have been reached before the operation commences, andthat this should be maintained during the operation. Attemptsto hasten the recovery from the anaesthetic by shaking thepatient or flipping with a towel should not be made. Children are very sensitive to the irritations of chloroform. Fig. 40.—Annandales Trachea Canula and Tube. Fig. 40. A full-size silver tracheotomy-tube, with its upper end ex-tended about Yz in. beyond its shield, is employed. There is a silver caphaving a short tube of silver projecting at right angles, and to the smallend of this cap a rubber tube can be connected. Fig. 40-I shows thetracheotomy-tube with the cap fitted upon it. This cap can be turned toeither side, thus permitting the India-rubber tube to project on the sidewhich will be most convenient to the operator. India-rubber tubing of thediameter of about ^2 in. is used. One end of this tube is fastened to the ap-paratus ; the other end is placed in a tumbler containing a small piece ofabsorbent wool at the bottcm, upon which chloroform or ether is from timeto time sprinkled. The whole apparatus is shown in Fig. 40-II. Annan-dale prefers to use chloroform. In beginning the administration the capis taken from the tracheal tube, and the
