Thoracic Epidural Space Identification

thoracic, epidural space, loss of resistance technique, CompuFlo® technology
Brief summary
The aim of this non inferiority trial is to assess the efficacy of CompuFlo® technology to identify the thoracic epidural space in relation to the gold standard loss of resistance technique.
Detailed description
This non inferiority trial shouts to adress whether the CompuFlo® technology to identify the thoracic epidural space is less efficacious to the gold standard loss of resistance technique (LOR). After informed signed consent patients that will be subjected to gynecological operations and meet the inclusion criteria will be eligible to participate. All operations will be performed under general anesthesia and thoracic epidural analgesia regardless of study arm. Patients will be randomly allocated into two study groups. In the first study group (Group LOR) the thoracic epidural space will be identified by the LOR technique and in the second study group (Group C) by the CompuFlo® technology. The primary outcome is the percentage of thoracic epidural space identification success in either study group.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of successful thoracic epidural space identification | Loss of sensation to cold 20 min after the first dose administered through the epidural catheter | The success of the thoracic epidural space identification |
Secondary
| Measure | Time frame | Description |

| Number of attempts to successful thoracic epidural space identification | Number of attempts to successful thoracic epidural space identification up to a maximum of 3 adressed as loss of sensation to cold 20 min after the first dose administered through the epidural catheter | Number of attempts to successful thoracic epidural space identification |
| Time to identify the thoracic epidural space | Time to insertion of epidural needle (Tuohy) in the supraspinous ligament to insertion of the epidural catheter | Time to identify the thoracic epidural space |
