Intra-operative evoked potential studies of newborn infants with myelomeningocele.

Somatosensory evoked potentials were studied in seven infants during surgery for repair of thoraco-lumbar myelomeningocele. All were operated on during the first 24 hours of life. Because anaesthetics were known to suppress somatosensory evoked potentials, narcotics and muscle relaxants were used for anesthesia. Before surgical dissection, stimulation of median nerves evoked cortical responses in five of the seven patients. After dissection, evoked potentials could be retrieved from the neural plaque with peroneal nerve stimulation in five of the seven infants. Stimulation of the neural plaque produced cortical responses in five of the seven but cortical responses with long latencies could be obtained from peroneal nerve stimulation in only two of the seven patients. In two patients lumbar-root stimulation distal to the plaque produced low-amplitude and delayed-latency cortical responses. These findings indicate that the distal nerves and neural plaque may have intact afferent connections with the cortex: therefore at surgical repair the neural plaque has been meticulously preserved.

Shunt system patency testing by lumbar infusion.

A simple and reliable bedside infusion test is described to evaluate shunt-system patency in adult patients with treated "normal" pressure hydrocephalus. Fifteen consecutive patients with ventriculoperitoneal shunts were tested by a two-part infusion test between 2 days and 32 months after shunt surgery. When we used the criteria presented, shunt patency could be established with certainty, and shunt malfunction could be established with relative certainty. Shunt malfunction was verified surgically.

Improving the nurse-patient relationship: a multi-faceted approach.

AIM: A Corporate Education Session was held to provide concrete strategies for overcoming several specific barriers in the daily nurse-patient relationship that negatively affect the patient, nurse, or both, and to provide the latest information about best practice as it affects nurses in renal care. METHODOLOGY: The session was led by a moderator who presented three video case studies to the audience. Communication strategies for recognising and overcoming nurse-patient communication barriers were presented. The audience expressed their views about each case study using voting pads, and a panel of experts addressed the comments of the audience and discussed guidelines for best practice in renal care. The panel comprised three experienced renal nurses, a senior nephrologist, and an expert in social interaction. CONCLUSIONS: Optimal treatment of patients with renal disease should include early treatment of anaemia, adequate levels of dialysis, and a multidisciplinary approach, responding to both the medical and the social needs of the patient.

Cranial computed tomographic demonstration of intracranial penetration by an orbital foreign body.

A 9-year-old boy suffered intracerebral penetration by a stick driven into his right orbit. Diagnosis was obtained by cranial computed tomography (CT), and this test directed appropriate immediate surgical intervention. Combined orbital exploration and craniotomy was followed by a gratifying recovery. The importance of CT in orbital and possible intracranial trauma is stressed.
