Angiotensin receptor blockers (ARBs) are commonly prescribed for the management of hypertension. However, refractory hypotension during general anesthesia caused by renin-angiotensin system blockade is a well-known potential complication in patients concurrently taking ARBs or angiotensin-converting enzyme inhibitors. 1 – 5 Therefore, it has been recommended that ARBs preferably be withheld for 24 hours prior to the induction of general anesthesia. 1 – 5 However, some reports suggest that continued preoperative administration of ARBs does

Administration of dexmedetomidine (DEX) is associated with the onset of bradycardia, biphasic blood pressure responses (brief hypertension followed by hypotension), and other cardiovascular complications. 1 – 4 Cardiovascular agonists must be appropriately used for treatment in the event of such issues. However, literature regarding ventricular tachycardia (VT) caused by cardiovascular agonists in patients under DEX-induced sedation is scarce. We present the case of a patient who received intravenous (IV) ephedrine to treat low

individuals on antihypertensive therapy, consideration should be given to patients taking ACEIs or ARBs who present for ambulatory dental surgery under general anesthesia. Continued perioperative use of ACEIs and ARBs has been associated with reduced or abnormal physiological responses to common intraoperative vasopressors, such as ephedrine, phenylephrine, and epinephrine, and is otherwise known as refractory hypotension. 3 We present the cases of 2 patients taking an ACEI or ARB with refractory hypotension successfully managed with the addition of vasopressin

predominates when combined with epinephrine, causing dilation of peripheral blood vessels in skeletal muscle and inducing hypotension. Therefore, epinephrine-containing local anesthetics should be carefully administered in patients concurrently taking antipsychotics, such as those with schizophrenia, autism, intellectual disability, and dementia. The Japanese Dental Society of Anesthesiology conducted a retrospective survey on the administration of epinephrine-containing lidocaine for dental patients taking antipsychotic medications at dental school hospitals and

We previously described the case of a patient with primary hypertension managed with telmisartan in which refractory hypotension during general anesthesia was not avoided despite withholding telmisartan for 24 hours before induction. 1 Telmisartan has the longest half-life of angiotensin receptor blockers (ARBs), and in that particular patient's case, withholding telmisartan for 5 days before a second general anesthetic positively resulted in the avoidance of severe refractory hypotension. Azilsartan has the second longest half-life of all

reported that intraoperative hypotension is likely to occur due to sympathetic inhibitory effects and impairment of baroreflex regulatory mechanisms. 13 Conversely, remimazolam, a new ultrashort-acting intravenous (IV) benzodiazepine, provides improved hemodynamic stability and is less likely to lower blood pressure compared to propofol. 14 Although known PONV risk factors include females, nonsmokers, history of PONV/motion sickness, and postoperative opioid use, intraoperative hypotension may be another risk factor. 15 It is not clear whether remimazolam and

in dentistry (>60%) 6 and is often induced by fear of or pain during the injection of local anesthesia. 7 VVS stems from abrupt changes in autonomic activity: increased parasympathetic activity (ie, increased vagal tone) that leads to bradycardia and decreased sympathetic activity that causes arterial relaxation resulting in hypotension. If the drop in cardiac output and blood pressure (BP) is severe, cerebral blood flow is substantially reduced, and loss of consciousness may occur. Because VVS is a reflex, signs and symptoms are usually observed rapidly (seconds
