[The experiment research of OB glue used in tracheoanastomosis].
Resect a segment of canine cervical trachea. The length of resected trachea is from 1-4cm and 5-8cm. In the first group, one dog was used for each length and two dogs were used for each length in the second group, therefore twelve were used in the experiment. The upper and lower ends were matched and seved by three stitches, and OB glue was used to coat in the anastomosis crevice, and at last the cre-vice was wrapped with a sheet of loose tracheal sheath. After the operation, irritating cough, barking, swallowing and free movement of neck didn't cause fistula. Nakedeyes and tissue examination showed that the healing of the anastomostic orifice was well and no stenosis was found. The glue membrane was absorbed completely within 1-2 months. Outside body anti-pulling force experiment (for 8 cases) showed that the anastomostic line can hold 100cm H2O stress and 2kg pulling strength if only OB glue was used to connect the resected ends. Hence, this experiment shows that the usage of OB glue for tracheal anastomosis is a safety, simple and convenient method.
