WebPhenylephrine is a synthetic noncatecholamine α1 agonist and produces dose-dependent vasoconstriction of cutaneous, muscular, mesenteric, splanchnic, and renal vasculature (see Table 22-1 ). Systemic arterial vasoconstriction increases systolic, diastolic, and mean arterial pressures, with reflex bradycardia. WebFeb 19, 2024 · Phenylephrine may cause reflex bradycardia, decreased CO, local tissue necrosis with extravasation, peripheral, renal, mesenteric, or …
WebPhenylephrine is the vasopressor of choice in spinal anaesthesia–induced maternal hypotension. However, it results in reflex bradycardia and decrease in cardiac output (CO), an effect that is perhaps less evident with the use of norepinephrine. We sought to evaluate the effect of phenylephrine and norepinephrine infusion on maternal systolic ... WebMay 27, 2024 · Consistently, inhibiting PATs with 2-bromopalmitate caused a blunted vasoconstriction response to phenylephrine in small arteries isolated from human kidneys. Therefore, DHHC21 contributes to...
WebFeb 12, 1998 · We conclude that, unlike the effects of administering norepinephrine under baseline conditions, norepinephrine infusion during endotoxic shock actually increases renal blood flow and that this effect is not the result of an increase in perfusion pressure alone. WebJul 13, 2024 · Decreased renal perfusion Variable CO Phenylephrine [ 2] Receptors: Strong alpha-1 Increased SVR, significantly No effect on PVR Increased BP No effect on HR No …
WebAug 1, 2011 · Arterial hypotension is a common anesthetic complication. Perfusion of vital organs depends largely on arterial blood pressure. Mean arterial blood pressure (MAP) below 60 mmHg and systolic blood pressures below 80 mmHg can result in reduced perfusion of the vital organs. Oxygen debt can ensue in morbidity and mortality.
WebTo maintain a high perfusion pressure, we decided to use a phenylephrine infusion; this drug is commonly used in clinical practice to increase the blood pressure during cardiopulmonary bypass (CPB). We thought that it would be interesting to compare its use with the use of dopamine in patients with preoperative abnormal renal function. the process or way of detecting radioactivityPhenylephrine is widely believed to reduce renal blood flow and thereby impair renal function. However, phenylephrine doesn't vasoconstrict the renal vasculature more than other vascular beds. Thus, it is possible that the effect of phenylephrine on renal blood flow, similar to the effect on cardiac output, may be context … See more Make no mistake, I'm not very fond of phenylephrine. I rarely use it (mostly for hypotensive atrial fibrillation). However, understanding phenylephrine is a prerequisite to understanding related vasopressors, … See more Poterman 2015 performed a RCT comparing norepinephrine vs. phenylephrine among sixty patients undergoing anesthesia with propofol and remifentanil.
