In this study, the neuroanatomy of the swine lumbar spinal cord, particularly the spatial orientation of dorsal roots was correlated to the anatomical landmarks of the lumbar spine and to the magnitude of motor evoked potentials during epidural electrical stimulation (EES). We found that the proximity of the stimulating electrode to the dorsal roots entry zone across spinal segments was a critical factor to evoke higher peak-to-peak motor responses. Positioning the electrode close to the dorsal roots produced a significantly higher impact on motor evoked responses than rostro-caudal shift of electrode from segment to segment...

BACKGROUND: Women laboring with epidural analgesia experience fever much more frequently than do women who chose other forms of analgesia, and maternal intrapartum fever is associated with numerous adverse consequences, including brain injury in the fetus. We developed a model of noninfectious inflammatory fever in the near-term pregnant rat to simulate the pathophysiology of epidural-associated fever and hypothesized that it would produce fetal brain inflammation. METHODS: Twenty-four pregnant Sprague-Dawley rats were studied at 20 days gestation (term: 22 days)...

Pneumocephalus is defined as air in the cranial cavity. Pneumocephalus can result from inadvertent dural puncture during lumbar epidural anesthesia or epidural steroid injection. Presently described is case of 41-year-old woman who had undergone lumbar disc hernia operation but due to ongoing complaints, was diagnosed as having failed back surgery syndrome. Percutaneous epidural neuroplasty was performed. In the operating room, under sterile conditions and under sedoanalgesia, Racz catheter was inserted in caudal area and guided to epidural area with scope...

Background: The primary aim of this study was to objectively assess the different spinal and caudal volumes that are of interest for caudal block volume dosing. Methods: Three directly assessed (volume of spinal canal/caudal space, volume of the dural sac and volume of spinal cord) and two derived volumes (volume of the epidural space and cerebrospinal fluid volume) were determined from magnetic resonance images (MRI) in 20 children (zero - three yr of age). The assessed volumes were correlated to age, height and weight...

We report the use of continuous electrical stimulation to assist with the preoperative placement of a thoracic epidural which was used to provide postoperative analgesia in a patient undergoing excision of a large scapular sarcoma. The size of the sarcoma and the surrounding area required to maintain a sterile surgical field necessitated that the epidural catheter be inserted several vertebral interspaces caudal to the level of desired catheter tip termination. The use of electrical stimulation allowed for sequential intercostal muscle stimulation during threading, which enabled the placement of the catheter tip at the appropriate spinal level to optimize analgesia...

BACKGROUND: Various factors influencing the distribution of sensory blockade in epidural anesthesia have been identified; however, reports on the effects of gravity and different postures in thoracic epidural anesthesia have been rare. Medications may be injected with the lateral decubitus or the neutral position; however, it is unclear whether the distribution range of medication is similar or significantly different between these 2 postures. OBJECTIVE: We focused on identifying the effect of different postures on the distribution of local anesthetics using epidurography at the thoracic level...

Persistent hiccup is uncommon, and the mechanism is poorly understood. We present the case of a 43-year-old male patient referred to the Algology department due to chronic back pain who developed what we believe a rare case of persistent hiccup secondary to caudal epidural steroid injection (CESI). The causes of hiccup are many and include electrolyte derangement, nutritional deficiencies, gastrointestinal disorders and instrumentation, cardiovascular disorders, renal impairment, central nervous system disorders, and drugs; however, the cause may be unknown...

BACKGROUND: Hypertonic dextrose injection (prolotherapy) is reported to reduce pain including non-surgical chronic low back pain (CLBP), and subcutaneous injection of 5% dextrose is reported to reduce neurogenic pain, hyperalgesia and allodynia. The mechanism in both cases is unclear, though a direct effect of dextrose on neurogenic pain has been proposed. This study assessed the short-term analgesic effects of epidural 5% dextrose injection compared with saline for non-surgical CLBP...

Thoracic paravertebral block (TPVB) is an efficient alternative to epidural anesthesia. The location of a catheter within the thoracic paravertebral space (TPVS) has been examined in the human cadaver studies, but it is unclear how it goes into the TPVS during catheterization. In this report, thoracoscopy was used to observe the thoracic cavity in real-time during a parasagittal in-plane approach of ultrasound-guided TPVB. During thoracoscopy, we observed whether a paravertebral catheter could be advanced caudally beyond the ribs into the neighboring TPVS...

Cervical injuries are the most common form of SCI. In this study, we used a neuromodulatory approach to promote skilled movement recovery and repair of the corticospinal tract (CST) after a moderately severe C4 midline contusion in adult rats. We used bilateral epidural intermittent theta burst (iTBS) electrical stimulation of motor cortex to promote CST axonal sprouting and cathodal trans-spinal direct current stimulation (tsDCS) to enhance spinal cord activation to motor cortex stimulation after injury. We used Finite Element Method (FEM) modeling to direct tsDCS to the cervical enlargement...

BACKGROUND: Caudo-lumbar and caudo-thoracic epidural anesthesia is an established technique that carries a low risk of dural puncture or spinal cord trauma in infants. Traditionally catheter advancement is based on external measurements. However, malpositioning of catheters are known to occur. We hypothesized that caudal-epidural catheters inserted under real-time ultrasound guidance may be more accurate than the accuracy of the measurements traditionally used for their placement. METHODS: We studied 25 patients, aged 2 days to 5 months, posted for abdominal or thoracic surgery, receiving general anesthesia followed by caudo-epidural continuous block...

BACKGROUND This study compared the efficacy and safety of 3 different anesthesia techniques used in total hip arthroplasty (THA). MATERIAL AND METHODS We allocated 198 patients preparing to undertake THA into 3 groups: general anesthesia group (GA group, n=66), caudal epidural anesthesia group (CEA group, n=66), and spinal-epidural anesthesia group (SEA group, n=66). We compared postoperative adverse effects occurring in patients of the 3 anesthesia groups. The Visual Analog Scale (VAS) score, Minimum Mental State Examination (MMSE) score, and β-amyloid (Aβ) expression were calculated to determine the effects of different anesthesia on the postoperative pain and cognitive dysfunction of patients...

BACKGROUND: Chronic lumbar radiculopathy has a lifetime prevalence of 5.3% in men and 3.7% in women. It usually resolves spontaneously, but up to 30% cases will have pronounced symptoms even after one year. AIMS: A prospective randomized single-blind study was conducted to compare the efficacy of caudal epidural steroid injection and selective nerve root block in management of pain and disability in cases of lumbar disc herniation. METHODS: Eighty patients with confirmed single-level lumbar disc herniation were equally divided in two groups: (a) caudal epidural and (b) selective nerve root block group, by a computer-generated random allocation method...
