Sažetak
Dystocia in reptiles is defined as any situation that prevents the female to lay or absorb unfertilized eggs. This is a very common phenomenon in snakes in captivity and can be caused by many factors. The diagnostics of dystocia is very complicate due to its multifactorial origin. The diagnostics may be facilitated by the case history, for example, if the owner gives the information that the oviposition has occurred recently but has not been completed and if the swellings are visible caudally in the celome cavity. X-ray is also used in the diagnostics. If the snake does not complete the oviposition within 48 hours, an intervention is required. The first line of treatment is a physical manipulation. The laying is tried to be induced by gentle massaging the eggs, by running the finger down the abdomen. The risk of such treatment is high because, if not gentle enough, this may result in oviduct rupture. If manual stimulation fails, the hormonal stimulation is applied. Oxytocin is administered in combination with calcium. The efficacy of oxytocin is better if it is administered within the first 48 hours form the onset of dystocia, although even in this setting its effectiveness is the lowest in snakes. If, following oxytocin treatment, the snake does not lay eggs, it is recommended to insert a needle through a snake's ventrum and to aspirate the egg contents. During this procedure caution is recommended to avoid the contamination of celomic cavity by the egg contents. The aspiration must be performed within 48 hours from the onset of dystocia because the egg contents begin to harden themselves after this time, making the aspiration impossible. Ones the egg contents are removed the snake can be leaved to pass the eggshells naturally or by the aid of oxytocin or, if the eggs are visible in cloaca, they can be removed manually by a forceps.
