(b)(4).Event took place 3 years ago in (b)(6) and has been reported now by hospital/ patient´s advocate.On (b)(6) 2014 "h l.00 am", the anesthetist inserted a peridural catheter for labor analgesia on the patient.Positioning was easy and according to usual guidelines.At testing the dose of 2% lidocaine, the anesthetist could not inject the anesthetic; in the hypothesis that there may be obstruction at the filter level,she replaced it, but without any benefit.So she hypothesized it could be the obstruction of the catheter due to malposition (kneeling, loop), so she retracted and then removed it completely.At extraction, she found that the catheter was sliced about 6-7 cm from the tip, probably by the tuohy cannula tip.
