Visceromotor and cardiovascular responses to colonic distension were measured in female rats, anesthetized with halothane in oxygen, in the proestrus, estrus, metestrus and diestrus phases of the estrous cycle. Ten rats were studied in each group and responses were measured at 5-min intervals for 60 min. A mixed model analysis of variance showed that there(More)
Sevoflurane causes a decrease in mean arterial pressure (MAP). We have studied in anaesthetized rabbits its interactive effects on MAP, the autonomic nervous system and baroreflexes. During sevoflurane administration changes in renal sympathetic nerve activity (RSNA) and heart rate (HR) were observed: (1) when the normal decrease in MAP occurred; (2) when(More)
A 27-year-old man complained of frequent chest pain and recurrent syncope for 3 months. He was in mild respiratory distress with a respiratory rate of 20/min and a heart rate of 94 bpm, regular in rhythm. His blood pressure was 120/70 mm Hg. Cardiac auscultation revealed a distinct early diastolic click followed by a grade 2/5 diastolic decrescendo murmur(More)
UNLABELLED We studied the effects of sevoflurane and remifentanil, alone and in combination, on phrenic nerve activity (PNA), resting heart rate (HR), arterial pressure (MAP), and changes in HR (delta HR) and MAP (delta MAP) evoked by electrical stimulation of tibial nerves in anesthetized rabbits. The 50% effective dose (95% confidence intervals) for the(More)
