The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pe...

Schwannomas (neurilemmomas) are benign tumors arising from the Schwann cells of the neural sheath. They are typically, well-encapsulated lesions which rarely adhere to the adjacent structures. In the chest, schwannomas are often seen within the posterior mediastinum and commonly originating along intercostal nerves. Several operative approaches have previously been described for the resection o...

Lower thoracic spinal cord stimulation (SCS) results in the generation of large positive airway pressures (Paw) and may be a useful method of restoring cough in patients with spinal cord injury. The purpose of the present study was to assess the mechanical contribution of individual respiratory muscles to pressure generation during SCS. In anesthetized dogs, SCS was applied at different spinal ...

Although preservation of the sensitivity of the nipple and areola is an important goal in breast surgery, only scant and contradictory information about the course and distribution of the supplying nerves is found in the literature. The existing controversy might be due to the difficulty in dissecting the thin nerves and to frequent anatomic variations that bias the results if only a small numb...

OBJECTIVE Applications for Abdominal Wall Vascularized Composite Allotransplantation may expand if a functional graft with decreased immunosuppressive requirements can be designed. We hypothesize that it is anatomically feasible to prepare a functional, innervated, and vascularized abdominal composite graft using a multilayered component separation technique. Including vascularized bone in the ...

Many clinical studies focus on the effects of acupuncture on digestive disorders. However, few studies describe the mechanism by which these effects are produced. We present some recent experimental work on the mechanism of acupuncture for reflex regulation of gastroduodenal function in anesthetized rats. In anesthetized rats, it has been proven that acupuncture to the abdomen excites sympathet...

Our intent is to report a case of intercostal neuralgia occuring as a complication of splanchnic radiofreqency ablation (RFA), due to a breach in the integrity of the insulating sheath of the RFA needle.A 48-year-old man presented to our pain clinic with upper abdominal pain due to chronic pancreatitis, recalcitrant to medical management. We decided to perform bilateral splanchnic nerve RFA in ...

Introduction: Diaphragm and lateral abdominal muscles frequently show sparing effects to muscle relaxants. This study compared visual estimation of neuromuscular transmission corrugator supercilii adductor pollicis (AP) with electromyographic measurements wall during recovery from vecuronium-induced intense block. Methods: 60 patients undergoing elective surgeries under general anesthesia were ...

These patients have suffered complete disconnection of the upper limb from the brain and spinal cord. Restoration of function involves reinnervation of muscles for control of the shoulder, the elbow and of the hand. The preponderance of root avulsions implies that there is a serious deficiency of donor nerves. Traditional nerve transfers using the spinal accessory nerve and the phrenic or the i...
