Intraoperative heparin in replantation surgery--an experimental study.

An experimental study to define the usefulness of heparin in microvascular surgery was undertaken. Fifty-four rabbits underwent replantation of an amputated ear. The animals were randomly divided into two groups--"heparin" and "no heparin," with 27 animals in each group. Arterial patency was recorded based on direct microscopic observation of the anastomosed vessels prior to wound closure and on subsequent viability or necrosis of the ear during the surgical procedure was markedly enhanced by the use of intraoperative heparinization. The overall patency rate for the heparin group was 74%, whereas that of the no-heparin group was 44%--a statistically significant difference. This study confirms the value of intraoperative heparin in experimental replantation surgery using a rabbit ear model.

Crossed fingers and other tests of ulnar nerve motor function.

All tests for ulnar nerve motor function require demonstration and explanation if they are to be carried out reliably. The tests used most commonly may be difficult to elicit, particularly in children or in the presence of an acute injury. The authors have found that the ability to cross the middle over the index finger is a reliable test of ulnar nerve function. This maneuver of "crossing the fingers" is in common usage from childhood on as a good luck sign and is elicited easily in the presence of an intact ulnar nerve. An annotated table is included of other tests that may be useful in evaluating ulnar nerve integrity.

Effect of nerve graft polarity on nerve regeneration and function.

To evaluate the effect of the polarity of nerve grafts, a 1.0 cm segment of sciatic nerve of 40 adult male Sprague-Dawley rats was excised. In 20 animals the nerve was sutured, maintaining the original polarity. In the order 20 the graft was reversed and sutured into place. Four to 6 months later, the nerves were exposed and directed conduction velocity and amplitude studies were done across the graft. No difference was found between the two groups. Comparison with the control side showed return of 70% to 75% of conduction velocity and amplitude. Nerve graft function was independent of nerve graft polarity.

Delayed definitive reconstruction of the burned hand: evolution of a program of care.

Experience gained in treating patients with hand burns admitted to an active Regional Burn Center has resulted in the development of a biphasic approach which separates early healing and later reconstructive surgical procedures. This schedule permits late definitive surgery on healed functioning hands and is accomplished in a single operation in most cases. This biphasic approach has led to better results at our institution in terms of hand function and appearance, and to a decrease in total numbers of surgical procedures. Reports of others using alternative methods and schedules, also with satisfactory results, are discussed.

Microsurgical anastomosis of vas deferens: an experimental study in the rat.

A patency rate of more than 90 per cent was achieved after 52 vasovasostomies. Satisfactory results were shown in both internally stented and nonstented anastomoses. A higher incidence of foreign body reaction was associated with silk sutures. Sperm granulomas and reduced patency were noted when superficial sutures were used indicating that a leakproof anastomosis is essential.

Cat scratch disease with involvement of intra-parotid lymph nodes. Case report.

A case of cat scratch disease, presenting as a parotid tumor, is described. In its oculo-glandular form, this disease may be associated with swelling of the intraparotid lymph nodes, and the possibility should be considered in the differential diagnosis of parotid tumors in children. A careful history, and skin testing with cat scratch antigen, may aid in the diagnosis of this condition.
