background activation of stress response during cardiac surgeries such as cardiopulmonary bypass (cpb) can increase myocardial oxygen demand and consumption through induced tachycardia and augmented peripheral vascular resistance. these physiologic consequences may lead to increased morbidity and mortality by putting too great a strain on the already compromised organ systems. material and meth...

INTRODUCTION Studies have shown that, at low doses and with careful titration, combination therapy with intrathecal ziconotide and morphine results in rapid control of opioid-refractory cancer pain. However, there is a lack of published data regarding the efficacy and safety of intrathecal ziconotide specifically for the treatment of neuropathic cancer pain. CASE SERIES Case reports of zicono...

BACKGROUND Intrathecal ziconotide is used to manage severe chronic pain. Although ziconotide is approved by the US Food and Drug Administration for monotherapy, it is sometimes used in combination with other intrathecal drugs for the management of intractable pain conditions in clinical practice. OBJECTIVES Evaluate the safety and tolerability of ziconotide combination therapy. STUDY DESIGN...

IMPLICATIONS Our report describes for the first time the continuous long-term intrathecal application of S(+)-ketamine in a patient with chronic pain and morphine tolerance. Intrathecally applied S(+)-ketamine led to a significant pain reduction and consecutively reduced the doses of intrathecal morphine required for pain relief even several weeks after the cessation of the 24-day period of int...

background: central nervous system (cns) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, intrathecal chemotherapy and cranial irradiation. the purpose of this study was to compare the effectiveness of intrathecal (it) cns chemotherapy alone versus combination of it chemotherapy with cranial irradiation for prevention of cns rel...

We investigated the capacity of intrathecal arachidonyl-2'-chloroethylamide (ACEA), a cannabinoid-1 receptor (CB1R) agonist, to inhibit referred hyperalgesia and increased bladder contractility resulting from acute acrolein-induced cystitis in rats. 24 female rats were divided into 4 groups: 1) intrathecal vehicle/intravesical saline; 2) intrathecal vehicle/intravesical acrolein; 3) intrathecal...

There is some evidence for the use of intrathecal morphine as a means to provide prolonged analgesia in selective cardiac surgical patients; however, hemodynamic effects are not well defined. This study was designed effect on parameters surgery patients. In prospective, double-blind study, 100 adult patients were randomized receive either 40 mg 0.5% hyperbaric bupivacaine alone (intrathecal [IT...

BACKGROUND AND OBJECTIVES The use of reduced intrathecal doses is advised for spinal anesthesia during cesarean delivery. However, there are inadequate data regarding the minimum effective dose of intrathecal bupivacaine for cesarean delivery. Preeclampsia is caused by an endothelial dysfunction leading to generalized vasoconstriction. Whether this can offset the pregnancy-induced decrease in i...

Neuropathic pain is caused by lesion or inflammation of the nervous system and characterized by the symptoms of allodynia, hyperalgesia and spontaneous pain. SIRT1 (Sir2) is a NAD-dependent deacetylase and is reported to regulate a wide variety of cellular processes including inflammation, aging and lifespan extension. Nevertheless, the role of SIRT1 in neuropathic pain is not fully understood....

BACKGROUND This study was designed to assess the postoperative analgesic effect of low-dose intrathecal morphine after scoliosis surgery in children. METHODS Thirty children, 9-19 yr of age, scheduled for spinal fusion, were randomly allocated into three groups to receive a single dose of 0 (saline injection), 2, or 5 microg/kg intrathecal morphine. After surgery, a patient-controlled analges...
