Cyclosporine A and cardiopulmonary bypass.

Another case report of interest was that of Shantha and Mani (3) in which a sterile Tuohy needle was passed over the epidural catheter and advanced to the epidural space, after which the Tuohy needle and lodged catheter were pulled out together. Although this method was carried out successfully, it has the obvious danger of possibly shearing the catheter and compounding the problem. I have found on occasion when extreme flexion in the lateral decubitus position was not adequate to facilitate removal of the epidural catheter, that rapidly injecting sterile saline, while at the same time exerting steady traction on the epidural catheter with the patient in the flexed position, enabled removal of the catheter. It would appear that increasing the turgor of the catheter by continuously filling it with saline, plus lubricating the surroundings of the catheter with the saline, allows the catheter to be released with greater ease. I hope that this simple technique will be of some clinical value to anesthesiologists who encounter the problem of trapped epidural catheters.
