Refractory Hypotension During Propofol/Fentanyl Anesthesia. A Report of Two Cases
Although serious hypotension or cardiovascular collapse during anesthesia induction with propofol is not rare, refractory hypotension during propofol anesthesia has not been reported. We describe two cases of refractory hypotension during propofol/fentanyl anesthesia which were refractory to lowering infusion rate of propofol and administration of vasopressors. We speculate that long-term hemodialysis and aortic regurgitation may be related to the refractoriness of hypotension in these cases, respectively. We emphasize the importance of discontinuation of propofol infusion and switching to an inhalational aneshetic technique in such cases.
