I developed a method for aspirating the egg while still inside the female so it will pass. Most vets don't want to perform the procedure because they are concerned about sepsis from the leaking egg.
When we have done it, we've always followed up with general antibiotic injections. So far, I haven't had any die that can be attributed definitvely to infections. When one has (rarely) died in the past, it was due more to just not being able to pass the egg even with it reduced in size.

Some vets try oxytocin, but I have never heard of much success in snakes using that method.
When combined with Calcium gluconate, we have had much better success than with Oxytocin alone. Small sample size, but I always start with Calcium gluconate BEFORE giving Oxytocin because (1) sometimes that takes care of the problem, (2) it is less likely to harm the snake than oxytocin, and (3) it is known to improve the efficacy of oxytocin in other animals.
On another note unrelated to the above, the newer vet references (check whatever the most recent Mader happens to be) are stressing the importance of waiting more. I have to agree with this: lots of snakes will pass them if given a few extra days. Granted, this needs to be decided on a case by case basis. We rarely have this problem in our colony (knock on wood, but I suspect it is due in part to larger cages for and a lack of obesity in our females), but waiting has done more good than all other methods combined. I think that's because many of us THINK they are eggbound when they just haven't passed an egg YET. There is no good biological definition of when a snake is eggbound as compared to "just hasn't laid the last egg yet." I don't know if such a definition can be made, but I wish there was one!
I have taken a more relaxed view towards when a female starts to worry me, and it seems the problems often DO solve themselves. Knock on wood. Also, I've found that the females that look like they are going to die with an egg in them the day after they laid the other ones are likely to die whether I do anything or not. In those cases, sadly, I suspect that the retained egg is a symptom and not the cause.
