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).

with retrograde cerebral perfusion or selective antegrade cerebral perfusion," Annals of Thoracic Surgery, vol.
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 .
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).
Partial cardiopulmonary bypass, hypothermic circulatory arrest
, and posterolateral exposure for thoracic aortic aneurysm operation.
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.
