[A method for the treatment of oviduct obstruction in cattle using CO2 insufflation into the uterus].

The investigations were carried out on 59 cows from Holstein half-breed, establishing that 8 cows suffered salpinx obstruction (5 cases with unilateral obstruction and 3 cases with bilateral obstruction). The authors are using an apparatus made by themselves, for insufflation of air in the obstructed uterus, and which is useful in desobstruction treatment, too. For diagnosis, CO2 was introduced inside of uterus. The authors used for treatment PBS (saline phosphate buffer) in addition with penicillin G, hydrocortisone and trypsin. Before air insufflation in uterus there will be infused 10-20 ml 2% Lidocaton. The cows must be examined in oestrus period, or 2 days after PGF2 alfa administration. The gas must be introduced under rectal palpation, and pressure must not be higher than 500 mm H2O column. If there is a permeable oviduct, after 15-20 sec. from gas introduction, ist is possible to palpate the filled oviduct. From ovary we can perceive a rustle produced by gas crossing in abdominal cavity. In case of salpinx obstruction, the treatment must be start as soon as possible. The utilized liquid for treatment will be introduce by gas pressure, inside of uterus and oviducts. Using this method, it managed the repermeability of oviducts at 3 from 8 treated cows. In each case, there were used 3 treatments at 48 h interval. After the second insemination (I.A.) 2 cows remained pregnant.
