We were able to place the catheter tip at T5 behind the spinal cord but unable to direct it over to the left side. The pump contains isobaric bupivacaine produced by our pharmacist, M. Golaz at "Pharmacie Internationale", at a concentration of 40 mg/ml and a pH of 6.5. No preservatives have been added.
After purging the catheter this morning we have now started the pump with an initial rate of 4 mg/24 hours. The result is a bilateral sensory block from T5 to T8 and complete disappearance of pain as well as the sympathetic component in the form of sweating in the pain-full territory described in our first report from March 12. The orthostatic function is well maintained.
