[Place of automatic oxytocin perfusion devices in the artificial induction of labor]

Automatic and self-regulated ocytocin perfusion sets, currently available, are able to precisely analyze the uterine activity in 15 minutes and automatically reduce the ocytocin output when a stable and effective uterine activity is obtained. The authors report the results of 41 inducements with the Autosoma pump and compare them with 358 inducements with manually controlled pumps. The duration and the amount of ocytocin perfused with Autosoma are comparable to the results obtained with manually controlled pumps. The frequent release of Autosoma alarms at the beginning of the experiment partially explains the lack of advantages of the automatic perfusion set.
