Dilute Versus Concentrated Epidural Bupivacaine in Labor
This study studies labor epidural analgesia and compares dilute (0.0625%) with concentrated (0.25%) bupivacaine.
We hypothesize that patients randomize to receive the concentrated drug will require more drug, will have a more profound motor block, will be more likely to require instrumental delivery and will be less satisfied than those receiving dilute epidural drugs.
This study examines the effect of two different local anesthetic concentrations used for epidural analgesia in labor. Patients are randomized to receive epidural bupivacaine, either as a concentrated (0.25%), or a dilute (0.0625%) solution, both administered by patient-controlled epidural analgesia (PCEA).
Allocation: Randomized, Control: Dose Comparison, Endpoint Classification: Pharmacodynamics Study, Intervention Model: Parallel Assignment, Masking: Double-Blind

Medical and Biotech [MESH] Definitions
The relief of pain without loss of consciousness through the introduction of an analgesic agent into the epidural space of the vertebral canal. It is differentiated from ANESTHESIA, EPIDURAL which refers to the state of insensitivity to sensation.
Circumscribed collections of suppurative material occurring in the spinal or intracranial EPIDURAL SPACE. The majority of epidural abscesses occur in the spinal canal and are associated with OSTEOMYELITIS of a vertebral body; ANALGESIA, EPIDURAL; and other conditions. Clinical manifestations include local and radicular pain, weakness, sensory loss, URINARY INCONTINENCE, and FECAL INCONTINENCE. Cranial epidural abscesses are usually associated with OSTEOMYELITIS of a cranial bone, SINUSITIS, or OTITIS MEDIA.

Blood Patch, Epidural
The injection of autologous blood into the epidural space either as a prophylactic treatment immediately following an epidural puncture or for treatment of headache as a result of an epidural puncture.
A local anesthetic that is chemically related to BUPIVACAINE but pharmacologically related to LIDOCAINE. It is indicated for infiltration, nerve block, and epidural anesthesia. Mepivacaine is effective topically only in large doses and therefore should not be used by this route. (From AMA Drug Evaluations, 1994, p168)
Hematoma, Epidural, Spinal
A rare epidural hematoma in the spinal epidural space, usually due to a vascular malformation (CENTRAL NERVOUS SYSTEM VASCULAR MALFORMATIONS) or TRAUMA. Spontaneous spinal epidural hematoma is a neurologic emergency due to a rapidly evolving compressive MYELOPATHY.
The purpose of this study to compare the use of spinal-epidural versus traditional labor epidural on maternal and fetal effects. The hope is to determine the safest and most effective epid...
The purpose of this study is to examine 4 different epidural dosing regimes of local anaesthetic solution in a series of 3 epidural injections over a period of 12 months to determine the o...
We propose performing a study in which we compare the effects of bupivacaine and fentanyl with a different drug combination − bupivacaine and clonidine. The principal research questions...
The investigators hypothesis is that spinal tetracaine with fentanyl and epinephrine used for CSE labor analgesia volume will last a significantly longer period of time that that of spinal...
60 female that care for pain control during second stage of delivery, will choose between epidural or systemic analgesia. Continuous ECG (3 lead)monitoring will be recorded during the seco...
The case of a 45-year-old male patient (body weight 52 kg, height 1.61 m) with a locally invasive gastric carcinoma infiltrating into the retroperitoneal space is reported. Because of severe cancer...
OBJECTIVE: To compare the analgesic efficacy of bupivacaine, bupivacaine + morphine, or bupivacaine + dexmedetomidine administered epidurally in dogs undergoing pelvic limb orthopedic surgery. STU...
PURPOSE: We quantified the dose-sparing effect of epinephrine by comparing the median effective dose (ED(50)) of intrathecal hyperbaric bupivacaine co-administered with epinephrine with the ED(50) of...
PURPOSE: The epidural electrical stimulation test (EEST) is a highly specific and sensitive test for confirming placement of the epidural catheter in the epidural space. The purpose of this study was...
BACKGROUND: Combined spinal-epidural anaesthesia is commonly used for elective caesarean section. Intrathecal injection produces rapid onset with minimal doses of local anaesthetic and epidural admini...
