Pulmonary oedema after high infusion rate of sulprostone.

symptoms such as headache or hypoacusia related to injection of saline boluses to be ‘serious complications from the procedure’. The mean duration of such ‘serious complications’ was 10 s, and in no case, these lasted for more than 30 s. These are well-known transient symptoms in patients during epiduroscopy or epidurolysis, especially in patients who are not under sedation, and are directly related to the pressure of injection. We did not mention cases of visual disturbance or intravascular injection because we did not have these complications. However, we included in the discussion a paragraph related to these transient symptoms and the importance of a more accurate control of the epidural pressure in order to avoid them. As for the possible risk of shearing the epiduroscope, it was not a problem in any case. We used an epidural needle (14 G RX COUDÉ) with special tip design that makes it possible to advance and withdraw the catheter without shearing it. We think epiduroscopy will find a place among the diagnostic and therapeutic tools in patients with chronic low back pain with or without radiculopathy, and especially in patients with failed back surgery syndrome. We have described a new method for performing epiduroscopy, which allows an interlaminar approach. It requires training and practice. In fact, we have improved on our personal results, now reaching 40% of very significant improvement in the last series with a very low incidence of side-effects.
