Use of coagulant spray glue (Glubran 2) for aerostatic purposes in pulmonary parenchyma resections in pigs: a preliminary study

BACKGROUND: The aim of our study was to test the aerostatic validity of a cyan-acrylic glue (Glubran 2), applied by means of a spray catheter, on an experimental pig model. MATERIALS AND METHODS: 15 young pigs were divided into three study groups of 5 based on surgical techniques: (1) atypical pulmonary resection with mechanical suturing and reinforcement with continuous suturing; (2) resection of the pulmonary parenchyma with a cold scalpel, followed by local application of Glubran 2; (3) atypical pulmonary resection with mechanical suturing followed by application of Glubran 2. RESULTS: The mean aerostasis time was calculated at 3.5 +/- 1.26 s. The histopathological analysis did not show any particular differences when comparing the effects of the treatments carried out with Glubran 2 spray glue and the standard treatments. No statistically significant differences were recorded in the short- and medium-term survival of pigs treated with Glubran 2 compared with the respective control groups. CONCLUSIONS: The application of Glubran 2 spray on wounds caused by pulmonary resections in pigs proved to have a rapid and effective influence for the purposes of aerostasis without significant differences in air losses and survivals.
