    Analysis of cardiac and pulmonary injuries resulting from an experimental penetrating thoracic injury
    (2014) Tokur, Mahmut; Ergin, Mehmet; Okumuş, Mehmet
    BACKGROUND: This study was planned to analyze the internal and external anatomical findings of cardiac injuries and the presence of accompanying pulmonary injuries in intentionally inflicted thoracic injuries to swine models. METHODS: We inflicted a penetrating heart injury in six suis domesticus female swine models. Two cardiac injuries, one on the left paratracheal of fourth intercostal space (ICS) and the other on the right side were inflicted on each model by the same researcher using a 20-cm long scalpel. All animals were then sacrificed for morphological evaluation. RESULTS: After strikes to the left fourth ICS, external evaluation showed that 50% of the subjects suffered a single laceration and that 33% suffered multiple lacerations. Internal evaluation showed additional intracardiac injuries in all five subjects. However, the subject that suffered a single laceration on the outer surface of the heart had multiple internal injuries while another subject that had multiple outer lacerations had only one intracardiac injury. Only three subjects suffered cardiac injuries and only two out of those three with pulmonary injuries after right fourth intercostal intrusions. CONCLUSION: This experiment has shown that external evaluation of the heart tissue may not alone be sufficient to determine the extent of cardiac injuries and accompanying pulmonary injuries caused by penetrating thoracic injuries.

    Approach to pleural effusions in the emergency department
    (2013) Tokur, Mahmut; Ergin, Mehmet; Girişgin, Abdullah Sadık; Demiröz, Mustafa
    Benign ve malign hastalıklar neticesinde plevral boşlukta sıvı salınım-emilim dengesinin bozulması sonucu oluşan plevral efüzyon sıklıkla karşılaşılan bir du- rumdur. Torasentez hem efüzyon tanısını teyit etme hem de efüzyonun niteliği hakkında ön bilgi edinme amacıyla yapılmalıdır. Alınan numuneden yapılan biyokimyasal, mikrobiyolojik ve sitolojik incelemeler tedavinin etiyolojiye yöne- lik olarak belirlenmesine yardımcı olur. Benign nedenlerin tedavisi altta yatan etiyolojiye yönelik iken, malign durumlarda ise ilk önce sıvı drenajı ve takiben yeniden sıvı birikiminin önlenmesine yönelik ileri tedavi gerekir.

    An experimental comparative study on classic tube thoracostomy and thoracostomy with a newly designed thorax drainage catheter
    (2016) Dündar, Zerrin Defne; Tokur, Mahmut; Ergin, Mehmet; Okumuş, Mehmet
    Background/aim: The collection of fluids, blood, pus, or air in the pleural cavity is a pathological condition requiring pleural drainage. A newly designed thorax drainage catheter in the prototype phase was used in this experimental study to test its efficacy. Materials and methods: A hemopneumothorax was first caused by a penetrating injury on the frontal axis of the sixth intercostal space on the right hemithorax with a scalpel on 6 female Sus domesticus swine subjects. After resting for 5 min, a tube or catheter was inserted. The same procedure with a tube thoracostomy or thorax drainage catheter was repeated on the left hemithorax. The time periods were recorded. After all procedures were completed, the thoracic organs were assessed for iatrogenic injuries. Results: In terms of time elapsed for procedure, statistically significant differences between the tube thoracostomy and thorax drainage catheter applications were identified (P0.05). Additional iatrogenic injuries were nonexistent for both groups. During the thorax drainage catheter application, a surgical set or the use of sutures was not required. Conclusion: This study showed promising results regarding the efficacy of the thorax drainage catheter for convenient use in prehospital and hospital settings by physicians with little experience with tube thoracostomy.

    A pilot experimental study of a catheter to facilitate treatment for penetrating cardiac injury
    (2014) Dündar, Zerrin Defne; Tokur, Mahmut; Ergin, Mehmet; Kürkçüoğlu, İbrahim Can
    Background/aim: Penetrating heart injuries result in high mortality. We designed a new catheter to facilitate the treatment of penetrating cardiac injuries and provide more effective initial bleeding control and fluid replacement. Materials and methods: The cardiac injury model was applied to 8 female 1-year-old Sus domesticus pigs. Subjects were grouped according to whether a Foley catheter or a newly designed catheter was placed into the heart through cardiac lacerations. Changes in systolic blood pressures, mortality, and problems encountered during surgery and other intraoperative findings were recorded. Results: There were higher mean blood pressure measurements in the newly designed catheter group during stages IV to VII. All subjects had tamponade and cardiac activity after completion of the repair of all lacerations in the catheter group, whereas in the other group only one subject did. Intraoperative direct fluid infusion to the heart through the catheters in the diastole was performed in all subjects of both groups. However, regurgitation from the cardiac cavity in the systole was seen only in the Foley catheter group. All of the intraoperative complications were seen in the same group. Conclusion: The newly designed catheter can provide effective initial bleeding control, better initial vital sign stabilization, and fewer intraoperative problems during primary repair of cardiac lacerations.
