peridural dose

Patient-controlled analgesia (PCA) is a delivery system with which patients self-administer predetermined doses of analgesic medication to relieve their pain. Since its introduction in the early 1980s, the daily management of postoperative pain has been extensively optimised. The use of PCA in hospitals has been increasing because of its proven advantages over conventional intramuscular injections. These include improved pain relief, greater patient satisfaction, less sedation and fewer postoperative complications...

Specialized prenatal care and substitution programs improve the perinatal prognoses of pregnant drug-abusers and their infants. Although methadone is well documented, little is known about high-dose buprenorphine (HDB). This prospective, multicenter (n = 35) observational study included 259 women on maintenance during pregnancy: 39% on methadone and 61% on HDB. Major findings were: 46% of them received good prenatal care; 62% had peridural analgesia; 12.3% delivered prematurely (<37 weeks); mean gestational age, 38...

of this study was to evaluate the effectiveness and the safety of the association of buprenorphine transdermal delivery system (TDS) (Transtec TDS) and peridural infusion of morphine and naropine, for the control of ischemic pain in patients suffering from peripheral arteriopathy. The administration of an opioid, pure agonist, as morphine, with a partial agonist opioid, as the buprenorphine, was used. Buprenorphine has shown a higher liposolubility in supraspinal districts, while the morphine acts above all on the mu receptor subtype of the spinal cord...

Pain control during labor is a primary objective of antalgic therapy. The use of the peridural as an elective procedure for labor analgesia is now corroborated by the international scientific community. Sometimes a combined spinal-peridural procedure is used together with the intrathecal administration of opioids to also cover the first stage of labor. Unfortunately, patients and/or gynecologists often request analgesia in a late stage of labor. The aim of our study was to evaluate the possibility of using a subarachnoid block alone for labor analgesia when this is requested at a late stage, that is, in advanced labor with cervical dilation greater than 7 cm...

AIM: Combining an opioid with peridural local analgesia is an excellent technique to control post-operative pain. Sufentanil is a widely used opioid agent, but its optimal dosage has not yet been defined. In this study we wanted to determine the best dose of epidural sufentanil in major surgery. METHODS: Before the operation, 45 major abdominal surgery patients received blended anesthesia through an epidural chest catheter. The patients were randomized into 3 groups of 15 subjects according to different sufentanil doses [0...

Nikolai Alekseevich Lopatkin, Academician of the Russian Academy of Medical Sciences, has contributed much to development of prostatic cancer (PC) diagnosis and treatment in the Russian Federation. N. A. Lopatkin headed specialists from the Research Institute of Urology who were the first in Russia to introduce into clinical practice the method of interstitial radiotherapy (brachitherapy) of local prostatic cancer (PC). A total of 58 PC patients 42 to 76 years of age were treated. They had stages T1bN0M0 (n = 5), T2aN0M0 (n = 36), T2bN0M0 (n = 11), T3aN0M0 (n = 6)...

AIM: The authors performed a prospective study in a series of patients undergoing combined general and epidural anaesthesia for major abdominal surgery in order to define if the epidural catheter inserted for postoperative analgesia induced in the short-term (7-8 postoperative days) any cytopathologically appreciable inflammatory response. METHODS: From April to September 2001, 20 consecutive patients undergoing combined general and epidural anaesthesia for major abdominal surgery at the National Cancer Research Institute and Villa Scassi Hospital (Genoa), were recruited after obtaining Institutional Ethics Committee approval and written consent from the patients...

OBJECT: The authors of clinical studies have demonstrated a significant association between the presence of extensive post-lumbar discectomy peridural scar formation and the recurrence of low-back and radicular pain. Low-dose perioperative radiotherapy has been demonstrated to inhibit peridural fibrosis after laminectomy in animal models. The present study was designed to evaluate the clinical efficacy of preoperative irradiation in patients with failed-back surgery syndrome due to peridural fibrosis who underwent reexploration and nerve root decompression...

To verify the effectiveness and the incidence of complication in the transcutaneal celiac plexus block with CT-guided in the patient with intractable upper abdominal cancer, using alcoholic solutions to different concentrations (50% and 96%), previous insertion of the peridural catheter. From December 1997 to June 2002, studies were carried out on 24 patients with CT-guided percutaneous coeliac plexus neurolysis including 17 men and 7 women with inoperable abdominal malignancy and two with chronic pancreatitis...

OBJECTIVE: To evaluate the effectiveness of uterine artery embolization in women with uterine myomas in terms of the clinical results for the relief of related symptoms. DESIGN: A pilot study on 26 women affected by uterine single myoma. SETTING: Tertiary level care in an university hospital. PATIENT(S): Twenty-six patients, aged 32 to 54 years, suffering of menorrhagia, pelvic pain, and abdominal mass for single myoma, intramural localization...

OBJECTIVES: To describe pharmacology and toxicology of ropivacaine. To assess the clinical efficacy of ropivacaine when used for postoperative epidural analgesia and to provide recommendations for clinical practice. DATA SOURCES: Search in the Medline data base of original articles in French and English published since 1995, using the following key words: ropivacaine, postoperative analgesia, epidural, caudal block. STUDY SELECTION: Prospective randomised studies in adults and children were selected...

We studied the selective block on patients receiving epidural Ropivacain (R) infusion for postoperative analgesia after major abdominal surgery. Twenty patients received R and twenty patients received Bupivacain (B) via peridural catheter during and after surgery. The patients' age ranged between 40 and 80 and they belonged to ASA I, II and III risk group. The epidural catheter was inserted one day before surgery and the proper position was tested by 80 mg Lidocaine. The epidural needle was inserted via T10-L1 interspaces in upper abdominal surgery and through L1-L3 interspaces in lower abdominal surgery...

UNLABELLED: Perinatal prognosis of pregnant drug abusers is better with intensive prenatal care and substitution maintenance programs. There is a large body of data in the literature on methadone (MTD), but very little on high-dose buprenorphine (HDB). The objective of this study was to compare 2 groups of pregnant women maintained on MTD or HDB for perinatal events. STUDY DESIGN: Prospective multicentric study; all neonates (NN) whose mothers has been maintained during pregnancy on MTD or HDB were included by 34 French perinatal centers with specialized staff for care of these pregnant drug abusers...

The prescription of heparin during pregnancy is an uncommon situation but a difficult one to manage because there are no reported therapeutic trials. The main indications are thromboembolic disease, valvular or congenital heart disease, cardiac arrhythmias and patients at high risk of thrombosis with blood clotting disorders. Non-fractionated heparin is the commonest form of anticoagulation in these circumstances as it does not cross the placental barrier; there are no teratogenic or haemorrhagic risks to the foetus...

PURPOSE: The scar tissue that forms after lumbar dissection is a severe complication and a cause of lumbar and radicular pain. It was recently shown that radiotherapy could inhibit peridural fibrosis after laminectomy. In this study, the efficiency of external irradiation was compared with spinal membrane application. METHOD AND MATERIALS: Thirty male New Zealand rabbits underwent L5 laminectomy. Ten rabbits each received a single fraction of 900-cGy external irradiation administered by 9-MeV electron beam 24 h after the surgery...

PURPOSE: To propose uterine myoma embolization as an alternative to myomectomy or hysterectomy in the treatment of symptomatic myomas; to evaluate the efficacy of the procedure in terms of clinical outcome, adopting all procedural and technical precautions to ensure minimal X-ray exposure and preserve reproductive potential. MATERIAL AND METHODS: Between April 1998 and February 2000, 26 patients, age range 32-54 years (mean 41 years), underwent uterine arterial embolization for menorrhagia, pelvic pain, and sensation of mass and pressure...

Epidural analgesia (EDA) is the most effective method of intrapartum pain relief. Its influence on the course of labor continues to be controversial. Although a cause-and-effect relationship has not been proven, this form of analgesia has been blamed for a host of adverse maternal/fetal events during labor, including prolonged first and second stage of labor, dystocia, malrotation of the fetal head and an increased risk of operative delivery (instrumental delivery, Caesarean section). Our own data from the Department of Obstetrics and Gynaecology at the University of Leipzig demonstrate that women with epidural analgesia had a longer duration of labor (the greater proportion taking more than 13 hours), although labor was often already protracted before the start of epidural analgesia...

OBJECTIVE: The critical analysis of the authors' standard protocol of termination of pregnancy during the second trimester. DESIGN: The prospective nonrandomised study. SETTING: Department of Gynecology and Obstetrics, 1th Faculty of Medicine, Prague. METHODS: We used a synthetic prostaglandin analog carboprost, 15-methyl-prostaglandin F2 alpha for induction of abortion during second trimester. It was administered in a single dose 500 micrograms...
