Excerpt
We thank Prof. Hilary P. Grocott for his interest in the consequence of phenylephrine for muscle oxygenation as determined by near infrared spectroscopy (NIRS; SmO2) [
1,
2]. Phenylephrine is an α-adrenergic agonist and we expected SmO2 to decrease in response to administration of phenylephrine but, as indicated by Prof. Grocott, veins are also sensitive to α-adrenergic stimulation. …
