circulatory arrest

Also found in: Dictionary, Thesaurus, Encyclopedia.

cir·cu·la·to·ry ar·rest

1. cessation of the circulation of blood as a result of ventricular standstill or fibrillation.
2. intentional cessation of circulation by temporarily stopping cardiopulmonary bypass flow during certain thoracic aortic operations; used with intentional profound total-body hypothermia to protect vital organs.

In univariate analysis, Deep Hypothermic Circulatory Arrest (P=0.026), positive inotropic drugs (P=0.031), postoperative stroke (P=0.016), postoperative acute renal failure (P=0.031), postoperative respiratory failure (P=0.000), showed significant univariate influence (Table 3).

The final consequence of all these conditions is that they determine a dramatic brain edema and cerebral parenchyma swelling with uncontrollable intracranial hypertension, leading to cerebral circulatory arrest and consequent cessation of brain electrical activity [15].
The use of cardiopulmonary bypass and circulatory arrest during surgery for tumor thrombi of the inferior vena cava extending above the diaphragm, in some cases, is accompanied by serious complications (coagulopathy, neurological disorders, and multisystem failure).
Cardiopulmonary bypass is first established then systemic cooling is elicited through hypothermic circulatory arrest (HCA.) HCA has to be timed correctly to avoid neurological insult.
Age, weight, male/female distribution, and CPB, clamping, and circulatory arrest durations did not differ between the 2 groups (Table 1).
Fatiguing handgrip performed at [40% of maximal voluntary contraction (MVC)] followed by circulatory arrest did not evoke an increase in CVR (P = not significant).
He presented a proof-of-principle study in which he trained 115 patients to recognize the prodrome of sudden circulatory arrest and initiate self-resuscitative cough CPR.
Those 10 variables were: (a) primary cardiac diagnosis (see Table 1), (b) type of surgical intervention (see Table 2), (c) age at surgery (days), (d) weight at surgery (kilograms), (e) duration of intubation postoperatively (days), (f) duration of stay in the critical care unit postoperatively (days), (g) evidence of vocal chord injury (yes/no) (by direct visualization of the chords by an ENT specialist), (h) duration of circulatory arrest (minutes), (i) evidence of diaphragm injury (yes/no), and (j) duration of oral feeding preoperatively (days).
For example, it remains unclear what length of time is safe for deep hypothermic circulatory arrest. Most studies have shown that children who undergo circulatory arrest for 30 minutes don't have any long-term problems.
