In B is shown the oval raw surface left to be brought together by sutures (_d_) after the buried suture (_b'_) has been tied. (_Diagrammatic._) ] Great care must be taken to see that no bleeding points are left unsecured, and a current of hot 1 in 4,000 perchloride solution should be allowed to play over the surface, after which the sutures are tied. Each suture should be left about an inch and a half long in order to facilitate removal later on. A gauze drain should be passed into the vagina and an antiseptic gauze pad placed over the perineum. [Illustration: FIG. 34. LACERATION OF THE PELVIC FLOOR. The double triangular surface has been denuded. (_Semi-diagrammatic, from a photograph._) The sutures, 1-5, on the operator’s right side are passed and tied; those on the left are passed but not tied. _a._ Anus _c._ Cervix _h._ Site of hymen. _p_{1}-p_{3}._ Sutures passed through the quadrilateral denuded surface. _r._ recto-vaginal wall. _s._ Speculum (Pozzi’s anterior retractor). _t_, _t._ Tenacula. The arrow denotes the direction in which the sutures are passed. ] =After-treatment.= The patient’s knees should be tied together, the urine drawn off by a catheter every six hours for the first 48 hours, and the wound kept as dry as possible. Throbbing and pain in the perineum with slight rise of temperature are generally indicative of suppuration taking place either between the flaps or along the sutures. A smart purge should be given on the morning of the third day and daily afterwards. If there are any scybala left in the rectum it is better to inject a little warm olive oil into it through a catheter before the bowels are expected to act. The patient should be allowed to get up on the twenty-first day. There should be proper control of flatus and motions from the date of operation. OPERATION FOR LACERATION OF THE PELVIC FLOOR The objects of this operation are twofold: first, to secure the torn ends of the levator ani to the lateral vaginal sulcus and perineum; and, secondly, to draw up or lift the pelvic floor, which is more or less depressed.
