Clinical application of compressed spectral array in long-term EEG monitoring of comatose patients

Background: Long-term EEG monitoring (LTEM), including amplitude-integrated (aEEG) or conventional EEG (cEEG), is increasingly being used in critically ill neonates. Despite an abundance of studies regarding the clinical utility of LTEM, much is unknown regarding provider attitudes toward this tool. We aimed to evaluate neurologist and neonatologist opinions regarding LTEM in the NICU and describe current Canadian practices. Methods: A 15-item questionnaire was developed with input from neonatologists and pediatric neurologists at two Canadian centres. The questionnaire was piloted at our hospital and subsequently distributed to Canadian neonatologists and pediatric neurologists. Results: All 16 local respondents use LTEM in the NICU. Neonatologists were more likely to combine aEEG and cEEG, and monitor for longer durations than pediatric neurologists. However, most pediatric neurologists would like to monitor more (71%), compared to neonatologists who were more likely to say that current monitoring practices are sufficient. High rates of neonatologists (88%) and neurologists (85%) are interested in attending an education session on LTEM. Conclusions: Preliminary data suggests neonatologists and pediatric neurologists differ in their approach to LTEM. Results from our national questionnaire will be analyzed shortly, and may inform the development of educational materials as well as future studies that involve multi-centre efforts.

Long Term Experiment

Long-term experiments with the total artificial heart (TAH) are a source of valuable knowledge for later clinical application. Our observations result from 66 long-term experiments on calves and one goat ranging from 30 to 314 days, which have shown the main possible complications in the early period (one month) and later in the experiment. Problems until the second month of pumping concern the clinical pendant of the TAH as a bridge for transplantation, i.e. surgical problems, blood coagulation disorders, infection etc. Later problems are high venous pressure or arterial hypertension, infection with septic thromboembolization, mineralization of the driving diaphragm, etc., and are more closely comparable to the conditions of permanent clinical use of the TAH. Faultless surgery, device function and the regimen of pumping are essential factors in every long-term experiment, just as in clinical application. Infection is a threat throughout any experiment, as in clinical cases. The TNS-BRNO-VII/clin/80 TAH has been implanted in six patients.
