BACKGROUND Despite the widespread use of implanted pumps for continuous intrathecal drug delivery, there have been no studies aimed at defining the effect of baricity and posture on drug distribution in the cerebrospinal fluid and spinal cord during the very slow infusion rates typically used for chronic intrathecal drug administration. METHODS Intrathecal microdialysis probes were placed at ...

Since the late 1980s, intrathecal (IT) analgesic therapy has improved, and implantable IT drug delivery devices have become increasingly sophisticated. Physicians and patients now have myriad more options for agents and their combination, as well as for refining their delivery. As recently as 2007, The Polyanalgesic Consensus Conference of expert panelists updated its algorithm for drug selecti...

We have developed a drug delivery system using a vasodilating drug that can be implanted intracranially at the time of surgery for aneurysm clipping, without systemic side effects or side effects associated with long-term intrathecal drug administration. We started our project on 1994 for making a slowly releasing drug delivery system in vitro because cerebral vasospasm occurs 4-14 days followi...

BACKGROUND Spinal anesthesia was considered as a reasonable anesthetic option in severe preeclampsia when cesarean delivery is indicated, and there is no indwelling epidural catheter or contraindication to spinal anesthesia. However, the ideal dose of intrathecal bupivacaine has not been quantified for cesarean delivery for severe preeclamptic patients. This study aimed to determine the ED 50 a...

in the long-term management of ulcerative colitis patients, repeat dosing maybe required. since 5-asa is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. the aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-asa deliver...

Background: Adding morphine as adjuvant intrathecal drug for cesarean section is a gold standard for post-operative analgesia according to literature, but because of frequent incidence of nausea, vomiting and pruritus, it has limited popularity. Various mechanisms have been demonstrated for the opioid-induced pruritus, with a variety of medications with different mechanisms of actions for preve...

Introduction: The use of epidural analgesia in patients with implanted intrathecal delivery devices is somewhat controversial. Major concerns include the risk of damaging the intrathecal catheter, the risk of infection, and the potential for interaction between the epidurally-administered and the intrathecally-delivered medication. In children with cerebral palsy, intrathecal administration of ...
