ObjectiveThis study aimed to compare the effects of remifentanil and dexmedetomidine on awareness during the induction of general anaesthesia.Material and MethodsNinety patients scheduled for elective caesarean section under general anaesthesia were included and randomly divided into three anaesthesia groups: 2 mg/kg propofol (control group); 2 mg/kg propofol and 1 µg/kg dexmedetomidine (dexmedetomidine group); and 2 mg/kg propofol and 1 µg/kg remifentanil (remifentanil group). All patients received routine monitoring, and Apgar scores at 1 and 5 minutes were recorded. The bispectral index and the isolated forearm technique were used to determine the depth of anaesthesia.ResultsBispectral index values at skin and uterine incisions and at delivery were similar among the groups. The number of patients who responded positively to the isolated arm technique during the induction period was also similar. One-minute Apgar scores in the control group were significantly lower and 5-minute Apgar scores significantly higher than those in the other groups.ConclusionThe effects of remifentanil and dexmedetomidine added to propofol on maternal awareness, neonatal Apgar scores, and bispectral index values were similar compared with propofol alone. However, it was observed that remifentanil controlled the haemodynamic responses to sympathetic stimuli in a better manner than dexmedetomidine.
Progressive supranuclear palsy (PSP) is a rare clinical syndrome characterized by postural instability and mild dementia. The classical clinical picture of PSP includes severe gait and balance disorder, general bradykinesia, frontal dementia, visual disorders, dysarthria and dysphagia. Aspiration pneumonia is the leading cause of death in advanced PSP. We aimed to present our experiences in a 72-year-old patient with PSP using MAO-B inhibitor as an update for anaesthesiologists. We recommend that it should be taken into consideration that patients with PSP have a high risk of aspiration due to dysphagia and use of various medical treatments with high drug interaction and regional anaesthesia should be preferred. At the same time, we recommend the careful use of opioids during general or regional anaesthesia if the drug cannot be discontinued in patients using MAO-B inhibitor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
