Abstract

Objectives: Irrigation and debridement constitute an important part of treatment of open fractures. We investigated the ef&#64257;- ciency of different irrigation methods and durations in cleansing contaminated bovine femur cancellous bone samples and the extent of tissue damage associated with irrigation. Methods: A total of 72 samples of 4x4x1 cm size were obtained from fresh frozen bovine distal femoral cancellous bone. The top surface of the samples were sawed to a 2-mm depth to cre- ate four squares equal in size. All the samples were contami- nated with construction sand using the same method and were then randomized to three irrigation groups (bulb syringe irriga- tion, high-pressure pulsatile lavage, and low-pressure pulsatile lavage), each consisting of 24 samples. The duration of irriga- tion was set as 3, 6, or 9 minutes for every eight samples of each group. After the irrigation procedure, the images were trans- ferred to a computer screen with a video-microscope camera and the number of sand particles on the samples were counted and irrigation-related macroscopic bone damage was assessed. Results: The lowest number of sand particles was found on the samples irrigated by high-pressure pulsatile lavage (p<0.001). The duration of irrigation did not affect the ef&#64257;ciency of cleansing in all the groups (p>0.05). The least irrigation-related bone dam- age was observed in samples irrigated by low-pressure pulsatile lavage for 3 minutes (p<0.01). The amount of bone damage was similar in all groups after irrigations beyond 3 minutes (p>0.05). Conclusion: Our &#64257;ndings showed that the most ef&#64257;cient method of cleansing contaminated bone samples was high-pressure pul- satile lavage and that prolonged irrigations did not enhance the ef&#64257;ciency of the irrigation method; however, high-pressure irriga- tion of 3 minute duration resulted in the greatest bone damage.

Özet

Amaç: Açık kırıklarda yıkama ve debridman, tedavinin önemli bir bölümünü oluşturur. Bu çalışmada, farklı yıkama yöntemlerinin ve farklı sürelerde yıkamanın kirletilmiş sığır femur spongiöz kemik örneklerinin temizlenmesindeki etkin- liği ve yıkamaya bağlı oluşabilecek kemik hasarı araştırıldı. Çalışma planı: Taze donmuş sığır distal femurundan 4x4x1 cm boyutlarında 72 adet spongiöz kemik örneği alındı ve her bir örneğin üst yüzeyi 2 mm derinliğinde oyularak eşit büyüklükte dört kare oluşturuldu. Bütün kemikler aynı yöntem kullanılarak inşaat kumu ile kirletildi. Örneklerden rastgele seçimle 24 adet- lik üç grup oluşturuldu. Bir gruba 20 ml’lik plastik şırınga ile yıkama uygulanırken, bir gruba düşük basınçlı (DBY), bir gru- ba yüksek basınçlı (YBY) yıkama uygulandı. Yıkama her bir gruptaki sekizer örneğe farklı sürelerde (3, 6 ve 9 dakika) uygu- landı. Yıkama işleminden sonra kemik örneklerinin görüntüle- ri video-mikroskop kamera ile bilgisayar ekranına aktarılarak üzerinde kalan kum tanecikleri sayıldı ve yıkama sonrası ke- mikte oluşan makroskobik doku hasarı değerlendirildi. Sonuçlar: Yüksek basınçlı yıkama uygulanan örneklerde, diğer iki yönteme göre anlamlı derecede düşük sayıda kum taneciği bulundu (p 0.05). Yıkama sonucu kemikte en az doku hasarı 3 dk’lık yıkamada DBY yönteminde görüldü (p 0.05). Çıkarımlar: Bulgularımız, kum taneciklerinin temizlenme- sinde en etkili yöntemin YBY olduğunu ve yıkama süresini artırmanın ek yarar sağlamadığını; ancak, YBY yönteminin 3 dakikalık yıkamada kemik dokusuna en fazla zarar veren yöntem olduğunu göstermiştir.
