简要总结
Few works have studied the area of analgesia covered by the spinal erector block in an objective manner, especially on the cephalo-caudal spread. The available data are dissection works or subjective data such as thermoalgesic or epicritic sensitivity.
This information would however be relevant in order to propose a better analgesia. Indeed, it could explain certain failures by insufficient diffusion of the block. The use of a multistage block could be relevant, especially in the case of osteosynthesis on several vertebral levels.
详细描述
Pupillometry makes possible to monitor analgesia based on the pupillary dilation reflex to pain. The goal is to establish an objective mapping of these type of analgesia from these data.

结局指标
主要结局
variation of the pupil size (in percentage)
时间窗: During the surgery
Evaluation the territory covered by the spinal erector block by variation of the pupil size (in percentage). Variation of the pupil size on stimulation will allow to deduce if the dermatome is covered by the spinal erector block analgesia.
