Factors affecting the distribution of continuous thoracic paravertebral block have never been examined. We designed this prospective, double-blind study to check whether continuous thoracic paravertebral block with a higher ropivacaine concentration would provide a wider segmental sensory block spread. Sixty consecutive patients undergoing pulmonary(More)
BACKGROUND The local anesthetic bupivacaine is thought not only to block sodium channels but also to interact with various receptors. Here, the authors focus on excitatory glutamatergic transmission in the superficial dorsal horn of the spinal cord with respect to its importance for nociceptive processing. METHODS The effects of bupivacaine on the(More)
A 26-year-old woman with Ehlers-Danlos syndrome (EDS) underwent posterior spinal fusion with instrumentation for scoliosis. General anesthesia was maintained using propofol and remifentanil. The procedure was performed examining the motor evoked potential (MEP) and somatosensory evoked potential (SSEP) of the lower extremities with the patient placed in the(More)
We evaluated an alternative technique for ultrasound-guided proximal level obturator nerve block that might facilitate needle visualisation using in-plane ultrasound guidance. Twenty patients undergoing transurethral bladder tumour resection requiring an obturator nerve block were enrolled into a prospective observational study. With the patient in the(More)
This is the first case report describing the epidural misplacement of an infusion catheter, which was intended to be located in the thoracic paravertebral space using an ultrasound-guided technique. The patient was a 57-year-old female undergoing a laparoscopy-assisted left partial nephrectomy. Before surgery, a Tuohy needle was inserted into the(More)
Emergence delirium (ED) is a common postoperative complication of ambulatory pediatric surgery done under general anesthesia with sevoflurane. However, perioperative analgesic techniques have been shown to reduce sevoflurane-induced ED. The primary objective of this investigation was to examine whether an ultrasound-guided ilioinguinal/iliohypogastric(More)
We report anesthetic management of a 6-month-old boy with Menkes disease who underwent three surgeries for vesicoureteral reflux, rupture of the bladder diverticulum, inguinal hernia, and gastroesophageal reflux. Menkes disease is a rare sex-linked disorder of copper absorption and metabolism. Anesthetic management of such patients is rather challenging(More)
BACKGROUND Nasogastric tube (NGT) insertion is an easy procedure that can be routinely performed under general anesthesia. However, for difficult cases, there are limited insertion techniques available in routine clinical practice, considering the flexibility of NGTs. The SUZY curved forceps are designed for the removal of pharyngolaryngeal foreign bodies(More)
Introduction: Transcranial motor evoked potential (TcMEP) monitoring is the gold standard for intra-operative neurological monitoring (IOM) of motor pathways during complex spine surgery because of its high sensitivity and specificity. However, although it is very low, the rate of false-negatives in TcMEP monitoring is not zero. Therefore, over-reliance on(More)
