“…O dispositivo de náilon aparentemente não demonstrou fragilidade após ser submetido ao processo de esterilização. Pesquisas demonstraram que a poliamida náilon 6.6 é resistente à temperatura de até 260°C [26]. A abraçadeira de náilon, também mostrou-se resistente à tração tanto nos testes físicos como para cerclagem na fixação interna de fraturas oblíquas de fêmur e prático, de baixo custo, fácil e rápida aplicação na orquiectomia [16,24,25].…”

RESUMOEm alguns criatórios os métodos de orquiectomia em eqüinos ainda são realizados por leigos e de forma empírica, sem atenção à higiene e a hemostasia preventiva dos vasos que compõem o cordão espermático, resultando muitas vezes em óbito do animal. O objetivo desse estudo foi avaliar a eficácia da abraçadeira de náilon, na orquiectomia em eqüinos, como método hemostático, possíveis complicações pós-operatórias e o custo do procedimento. Foram empregados 24 animais machos não castrados, sem raça definida (SRD), clinicamente saudáveis, com peso corporal variando entre 300 kg e 400 kg e faixa etária entre três a oito anos. Avaliou-se os resultados dos procedimentos cirúrgicos por meio de exames clínicos, hematológicos e a ocorrência de complicações trans e pós-operatórias. Além da presença de edema nos eqüinos de todos os grupos, ocorreu um óbito quando se utilizou o emasculador. A abraçadeira de náilon subjetivamente avaliada mostrou-se resistente a tração exercida no local da aplicação e quando comparada ao uso do emasculador e categute apresentou menor custo e reduziu o tempo de duração do procedimento.Descritores: castração, eqüino, hemostasia, poliamida náilon. ABSTRACTIn some horse breeding farms, the orchiectomy methods is still being practiced not scientifically by unprofessional people, without attention to hygiene and preventive hemostasy of the vessel from the spermatic cord, which usually results in death. The aim of this study was to evaluate the efficacy of the nylon clamp as an hemostatic method on the orchiectomy in equines, to describe possible post operative complications and the cost of the surgical procedure. 24 non castrated male equines, not defined breed, clinically health, between 300 and 400 kg of corporal weight and between three and eight years old were studied. The results of the surgical procedures were evaluated by clinical and hematologic exams and the occurrence of trans and post operative complications. There was edema in the animals of all groups and one death when the emasculator was employed. The nylon clamp was subjectively evaluated and have shown resistance to traction upon the place of the ligature when compared to the use the emasculator and catgut, lower cost and have decreased the time of surgical procedure. .

Nylon Clamps for Orchiectomy Hemostasis in Swines

et al. 2018

Orchiectomy is often employed in zootechnical activities with the main objective of carcass improvement; therefore, the search for alternatives that minimize surgical trauma, operative time and mainly decrease operating costs is pertinent. The nylon clamp is a tensile strength device, well tolerated by the body and inexpensive. It has been used as a hemostatic method in several surgical procedures. The aim of this study was to evaluate the operability and functionality of this device for the preliminary hemostasis of the spermatic cord in the open orchiectomy, comparing it to the surgical nylon thread. Twenty male pigs were divided into 2 experimental groups: GI (clamp - 10 animals) and GII (surgical nylon thread - 10 animals). The surgical time, the degree of hemostasis, the size of the incision, the presence or absence of edema and secretions, besides the weight gain were evaluated. For analysis of inflammatory response, fibrinogen was assessed. Compared to surgical nylon, the clamps presented advantages over surgical time and blood loss. It was concluded that the use of nylon clamps for hemostasis of the spermatic cords of pigs submitted to orchiectomies reduced the total time of surgeries, as well as hemorrhages, when compared to hemostasis with nylon thread. Furthermore, weight gain and induction of inflammatory response were not influenced by the hemostasis method used.

“…Adjustable nylon ties are devices produced from the same material of surgical nylon wire, polyamide 6.6 [19,21,30] and can be sterilized in the autoclave without loose the tensile strength [1,25,27]. This device have been used in different surgical procedures of soft tissues in small animals [1,4,5,9,15,17,25,27,29]; orthopedic surgical procedures in human patient [22,28] and in small animals [10,16].…”

Background: Adjustable nylon ties polyamide 6.6 is devices produced from the same material of surgical nylon wire and have been used in different surgical procedures in small animals and in human patient. Reports regarding the use of these devices as secondary fixation technique of femoral diaphyseal fractures in animals are rare in the literature. The aim of the present report case was to describe the use of adjustable nylon tie polyamide 6.6 as secondary fixation technique in a 3-year-old dog and 4-month-old cat, diagnosed with femoral diaphyseal fractures.Cases: Case 1. A 3-year-old female dog was presented with reluctance to support the left hind limb, with 5 days’ duration. Pain and edema on the left femoral diaphyseal region was identified. The limb was submitted to radiographic exam and revealed a closed, complete and comminuted fracture of the diaphysis of the femur, and was decided to perform a surgical stabilization by open reduction through primary fixation with intramedullary pin, and secondary fixation of bone fragments with adjustable nylon ties polyamide 6.6, as a substitute of steel cerclage wire. The bone fragments were alignment and fixated with five polyamide nylon ties. The excess was removed with a scalpel blade along the lock. Seven days after surgery the skin sutures were removed and were observed reluctance to support the left hind limb. Physiotherapy sessionswere prescribed. Forty days after the surgery was performed a radiographic exam of the left hind limb which revealed alignment of the bone axis. Six months after the surgery, the owner reported that the dog supported the left hind limb.Case 2. A 4-month-old female cat was presented with history of trauma, with 24 h’s duration, and reluctance in supporting the left hind limb. On physical examination there was identified pain on the left femoral diaphyseal region. Radiographic examination revealed a closed, complete and simple fracture of the diaphysis of the femur, and a surgical stabilization through primary fixation with intramedullary pin, and secondary fixation with three polyamide nylon ties was performed.Seven days after the surgery were observed reluctance to support the left hind limb. Three months after the surgery, the owner was contacted and he reported that the cat was supported the limb.Discussion: Adult dogs are more susceptible to diaphyseal fractures and so does the dog in the present report. On the other hand, young cats present high metaphyseal fracture rates due to the metaphyseal growth plate. However, the cat in the present report was different since it was 4-month-old and presented diaphyseal fracture. Different from steel cerclagewires, polyamide nylon ties were used as secondary fixation in diaphyseal fractures for the reason that of their stability in this kind of fracture, no tissue reaction and minimal tissue trauma. The adjustable nylon ties polyamide 6.6 were already used in different surgical procedures in human patients and animals. Complications reported in the literature due to theiruse were associated with erroneous surgical techniques. Adjustable nylon ties polyamide 6.6 proved to be efficient as bone cerclage device in diaphyseal multiple and simple fracture, as well as gave stability to the herein assessed adult dog and young cat, besides not inducing foreign body reactions.Keywords: small animals, polyamide, bones, cerclage, surgery.
