Skin simulation for minor surgical procedures.

A simulated skin preparation is described which is made by bonding siliconized rubber to a latex foam base. This composite material, which simulates both the dermis/epidermis and subcutaneous fat, provides a realistic model which can be used to teach excision of skin lesions and a variety of suturing methods. We believe that this simulator is of value not only for surgeons in-training but also will allow general practitioners to improve their technical skills in performing minor surgical procedures.

Surgical simulation for general practitioners.

The White Paper (1) and its implementation means that general practitioners will perform many more minor procedures. Training and retraining will be required in the manual skills necessary to handle instruments and remove such conditions as surface lesions. We describe a training aid based on porcine dermis which allows a practitioner the opportunity to acquire such skills. It may also be useful for training paramedical personnel.

Simulation in surgical training using freeze dried material.

The acquisition of manual dexterity and surgical skills is usually achieved in the operating theatre under supervision. We describe an efficient way of learning intestinal anastomosis procedures with the use of gamma irradiated, lyophilized porcine or bovine tissues together with a purpose designed holding jig. Preliminary evaluation of this method with untrained subjects showed that they were able to improve their performance. Because the tissues are sterile, health hazards are avoided and no special laboratory facilities are required. This approach has promise as an aid to evaluation as well as training.

Clinical experience in neurosurgery with absele: a new absorbable haemostatic bone sealant.

Control of bleeding from the cut end of bone in neurosurgery is a necessity. In certain clinical situations, control of bleeding may be difficult because of the underlying pathology. Existing methods of control of haemorrhage with standard bone wax can interfere with subsequent healing. This paper presents the clinical results in 259 patients in whom a new absorbable bone sealant, Absele, has been used. Absele is a paste made from stabilised fibrin and soluble collagen and absorbs totally with minimal tissue reaction in approximately three weeks.

Properties of bovine fibrin absorbable implants.

The assimilation characteristics of absorbable bovine fibrin implants in an experimental situation are described, and the effect of delaying absorption with formaldehyde treatment is demonstrated. Essentially, in vivo in the rat, Biethium fibrin implants are absorbed in approximately four to eight weeks because of the polymorphonuclear leukocyte digestion. An indication of the clinical uses in stress incontinence and hemorrhage of the liver are given, together with a look at the future of some of the other areas in which this absorbable, biologic plastic may fit into the surgeon's armamentarium to replace deficient or destroyed tissue.

Ethibond--a new polybutylate coated polyester suture.

This paper describes a new plastic polymer coating, polybutylate (polytetramethylene adipate), which, when applied to braided polyester fibre produces a new suture material--Ethibond. The advantages of this new suture material are improved handling properties, reduced tissue drag and minimal tissue reactivity. The paper details the physical and biological properties of the material.
