Lumbar disk herniation is common. Because of the posterior longitudinal ligament, migration usually occurs into the ventral epidural space. Rarely, fragments migrate into the dorsal epidural space. A 57-year-old man presented with lower back pain and weakness on right hip flexion and right knee flexion. He had lower back pain 1 day previously and received a transforaminal epidural block at a lo...

conclusions the results of our study indicate that for patients who are scheduled for hip surgery, both continuous paravertebral and continuous epidural analgesia are effective in controlling postoperative pain but that the former has several crucial advantages. results mean arterial pressure was significantly lower in the epidural group compared with the paravertebral group from 2 hours after ...

The recognition of needle entry into an epidural space is a pivotal moment in cervical, thoracic, or lumbar epidural injections. Its significance cannot be overestimated. Regardless of how experienced you are, realizing that you are approaching an epidural space makes your heart beat faster. The safety of the procedure and its success rate depends upon proper and reliable identification of the ...

are caused by trauma or iatrogenic interventions, and to the best of our knowledge, only 17 cases associated with bronchial asthma have been reported in the literature up to February 2012. The mechanism by which this condition is considered to develop is the exfoliation of transudative air in the posterior mediastinum space due to high bronchoalveolar pressure, and the subsequent invasion of th...

The incidence of epidural needle-induced post-dural puncture headache (PDPH) in parturients following dural puncture with a large bore (18-gauge) needle has been reported to range 76-85%. We describe seven cases in which the performance of epidural anesthesia in parturients was complicated by an unintentional dural puncture with an 18-gauge epidural needle. In all seven cases, the unintentional...

Lumbar epidural anesthesia is commonly used for labor analgesia. The 'loss-of- resistance' to air technique (LORA) is generally employed for recognition of the epidural space. One of the rare complications of this technique is pneumocephalus (PC). Here we describe the case of a parturient who developed a frontal headache when locating the epidural space using LORA. On the second day after epidu...

BACKGROUND We report a prospective, randomized study to evaluate ultrasound guidance for epidural catheter placement in children 0-6 yr of age. METHODS Epidural catheters were placed at lumbar or thoracic cord levels in 64 children undergoing major surgery, using either ultrasonography or loss-of-resistance (LOR) for guidance. Using a 5-10 MHz linear ultrasound probe, the neuraxial structures...

Vacuum disc phenomenon is a collection of gas in the intervertebral disc space but rarely causes nerve compression. However, some rare type of vacuum phenomenon in the spinal canal may bring about posterior gas displacement within the epidural space. The authors describe two patients with symptomatic epidural gas-containing cyst that seem to be originating from vacuum phenomenon in the interver...

BACKGROUND AND OBJECTIVES The objective of the present study was to evaluate the use of the ultrasound on the determination of the depth of the epidural space. METHODS Sixty patients were included in this prospective study; the L(3)-L(4) space was initially identified by palpation followed by the ultrasound measuring the depth of the epidural space (PU). After the epidural puncture the measur...
