| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Spinal Ultrasound | Diagnostic Test | Spinal Ultrasound is performed by an observer who records ultrasound characteristics of the intervertebral space chosen by the anesthetist who will practice spinal anesthesia | ||
| Spinal Anesthesia | Procedure | Spinal anesthesia is performed by an anesthetist after the observer recorded ultrasound characteristics of the intervertebral space chosen by the anesthetist, who is blinded to the ultrasound evaluation. |
| Measure | Description | Time Frame |
|---|---|---|
| Ultrasound View | Ultrasound visibility of Dura Mater complexes on the intervertebral space chosen for spinal anesthesia | 10 minutes |
| Difficulty in performing spinal anesthesia | Difficult spinal anesthesia includes: failure, procedure lasting more than 400 seconds from the insertion of the needle to the deliquoration; a number of needle replacements greater than 10; a change of the clinician practicing spinal anesthesia. | 20 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Failure Rate | Failed Spinal Anesthesia | 20 minutes |
| Duration | Spinal anesthesia duration (expressed in seconds) from the insertion of the needle to the deliquoration |
