BACKGROUND Guidelines for cancer pain management include nonsteroidal antiinflammatory drugs with opioids administered in a time-contingent manner. This study was designed to evaluate the role of oral ketamine or transdermal nitroglycerin polymer, a nitric oxide donor, as coadjuvants to oral morphine in cancer pain therapy. METHODS After institutional(More)
STUDY OBJECTIVE To examine analgesia and adverse effects of combination epidural pain therapy consisting of administration of morphine with either low dose of ketamine, neostigmine, or midazolam in terminal cancer pain patients. DESIGN Randomized double-blind study. SETTING Teaching hospital. PATIENTS 48 terminal cancer patients suffering from chronic(More)
This study was designed to examine postoperative analgesia with intrathecal neostigmine in a randomized, blinded trial with morphine as the active control in patients undergoing anterior and posterior vaginoplasty. A secondary aim was to provide preliminary data on the interaction between these two drugs. The incidence of adverse effects was also assessed.(More)
BACKGROUND Sufentanil is a potent but short-acting spinal analgesic used to manage perioperative pain. This study evaluated the influence of transdermal nitroglycerine on the analgesic action of spinal sufentanil in patients undergoing orthopedic surgery. METHODS Fifty-six patients were randomized to one of four groups. Patients were premedicated with(More)
BACKGROUND Intrathecal neostigmine causes analgesia by inhibiting the breakdown of acetylcholine. Experimental data suggest that the production of endogenous nitric oxide is necessary for tonic cholinergic inhibition of spinal pain transmission. The purpose of this study was to determine whether association of transdermal nitroglycerine would enhance(More)
STUDY OBJECTIVES To examine analgesia and adverse effects following transdermal application of nitroglycerine (a nitric oxide generator) combined with oral morphine, in cancer pain patients. DESIGN Randomized, double-blind study. SETTING Teaching hospital. PATIENTS 36 patients suffering from cancer pain. INTERVENTIONS Patients were divided into two(More)
BACKGROUND AND OBJECTIVES The efficacy of operatively administered spinal neostigmine to provide analgesia and that of different antiemetics to prevent neostigmine-related nausea and vomiting were evaluated in patients undergoing tibial or ankle reconstruction. METHODS One hundred patients were randomized to five groups (n = 20). The intravenous(More)
BACKGROUND Intrathecal neostigmine produces analgesia in volunteers and patients. However, the use of epidural neostigmine has not been investigated. The purpose of the current study was to define the analgesic effectiveness of epidural neostigmine coadministered with lidocaine and side effects in patients after minor orthopedic procedures. METHODS After(More)
UNLABELLED We examined the postoperative analgesia of a controlled delivery ketamine transdermal patch after minor abdominal gynecological surgery using lidocaine epidural blockade. Fifty-two patients were randomized to one of two groups. Epidural anesthesia was performed with 25 mL 2% plain lidocaine. At the end of the surgical procedure, a controlled(More)
