The reason for failed treatment is that, the consumption of surface active material results in pulmonary collapse and the release of inflammatory mediators, barotrauma and shearing injury caused by mechanical ventilation aggregate lung injury, the release of endogenous NO of those patients is reduced, and moreover pulmonary arteriospasm
can induce pulmonary hypertension; therefore, mechanical ventilation alone is lowly effective for some newborns with severe respiratory failure.12,13
Lastly, elevation of sympathetic nerve activity during sexual intercourse may be accompanied with cerebral arteriospasm
, which further aggravates cerebral ischemia.
(27.) Nilson and Renclahi (1958): Retinal arteriospasm
(3) Complications following ABG sampling are rare but may include fainting, arteriospasm
(where reflex constriction of the artery prevents withdrawal of blood) and haematoma.
In fact, it has been known for decades that Phenergan[R] can cause gangrene when injected intra-arterially, (74) and the package insert specifically contraindicated intra-arterial injection: CONTRAINDICATIONS Under no circumstances should PHENERGAN Injection be given by intra-arterial injection due to the likelihood of severe arteriospasm
and the possibility of resultant gangrene (see WARNINGS--Severe Tissue Injury, Including Gangrene).
Also, I was taught that one should never use an evacuated tube to draw blood from an artery because there is a risk of causing arteriospasm
, but I cannot seem to find this anywhere in the literature.
by blocking arteriospasm
in the brain through the use of Ca+channel blockers (e.g., verapamil, flunarizine).
Besides lowering high blood pressure, adequate magnesium produces relaxation of the muscles, be it coronary arteriospasm
(Prinzmetal's angina) or otherwise, controls the most unresponsive tachyarrhythmia (rapid, irregular heart rate), can calm nervous tension, and help insomina.
