Suturing

Considerable practice is required to suture incisions and lacerations quickly and accurately. Yet these skills are not beyond the reach of the average layman gifted with manual dexterity or an interest in mastering the art. If possible, practice your suturing techniques on a piece of sponge rubber, upholstery, or even a pillow. Some surgeons become skilled in knot tying, practicing on door handles or in the automobile while traveling. The accompanying diagrams, located on pages 178 to 189, help demonstrate the principles of the three basic methods of surgical knot tying. The one described as an “instrument tie” utilizes a hemostat or needle holder, while the others require only skillful fingers for proper use. I would suggest that a novice begin with the two-handed tie and instrument tie, adding more complex forms as skill is gained.
Avoid tying the sutures so tightly that insufficient blood flow to the skin edges results. This would cause delayed and incomplete healing of the wound.
“Approximate, don’t strangulate” is the watch word for closure of lacerations with sutures. Human bites, animal bites, and lacerations opened longer than 12 hours, or those grossly contaminated are not sutured, but allowed to granulate and heal by secondary intention.
The placement of sutures and selection of suture material will be described in the following sections, as the various types of lacerations and their special care are considered. In a home-like setting it is possible to make the appropriate needles, like bending a sewing needle, sharpening the point in a chisel fashion to better penetrate the skin. Silk or cotton can be boiled along with the needle, thus sterilizing it for use in suturing. Prepared packages, that come already sterile, are available from suture manufacturing companies and can be obtained in various sizes and needle styles. Remember to consult the suture use manual for aid in selecting the appropriate sutures.
