arterial versus venous fluid resuscitation; restoring cardiac contractions in cardiac arrest following exsanguinations

چکیده
conclusions ia fluid resuscitation is superior to iv resuscitation in hemorrhagic shock induced cardiac arrest. results while iv rl infusion failed to restore chest motion in mice (n = 5), ia rl infusion restored chest motion in all mice examined (n = 6) (p = 0.0067). in three mice, iv rl infusion after cardiac arrest showed no effect on cc. after failure of venous infusion, ia rl infusion was performed which resulted in restoration of cc for 13.33 ± 1.76 minutes. in eight mice, intermittent ia infusion of rl after cardiac arrest, sustained cc for 31.43 ± 10.9 minutes (p = 0.017). objectives we hypothesized that ia fluid resuscitation is more effective than iv resuscitation in restoring cardiac contractions (cc) of cardiac-arrested mice following severe hemorrhagic shock. methods mice (n = 22) were anesthetized using ketamine/xylazine. arterial and venous systems accessed through cannulation of the carotid artery and the jugular vein, respectively. as much blood as possible was aspirated from the carotid artery access. mice were observed until the complete cessation of chest wall motions. following 30 seconds delay, iv (n = 5) and ia access (n = 6) were used for fluid resuscitation using ringer lactate (rl) in a similar volume to the aspirated blood. mice were observed for restoration of chest wall motions. in phase-iiof the study, after cessation of chest motions, mice (n = 11) underwent a thoracotomy and ccs were observed. in three mice, iv rl infusion after cardiac arrest failed to restore ccs and was followed by ia rl infusion. in eight mice, following cardiac arrest intermittent ia rl infusion was performed. background arterial cannulation and intra-arterial (ia) fluid and blood resuscitation in the patients with severe shock is an easier approach compared with the intravenous (iv) access if concerns regarding the efficiency and safety of this approach are addressed.

Background: Arterial cannulation and intra-arterial (IA) fluid and blood resuscitation in the patients with severe shock is an easier approach compared with the intravenous (IV) access if concerns regarding the efficiency and safety of this approach are addressed.

متن کاملThe Aassociation between Pre-Cardiac Arrest Comorbidity and Unsuccessful Cardiopulmonary Resuscitation in Patients with Cardiac Arrest
Background and Objective: Patients suffering from cardiac arrest (CA) have poor prognosis and survival. The association of pre-arrest comorbidity with unsuccessful resuscitation in patients with CA is far from clear. The aim of the present study was to investigate the association between pre-existing comorbidity and unsuccessful resuscitation following CA in Iranian patients. Materials and Met...

Arthur B. Sanders The modern era of cardiopulmonary resuscitat ion (CPR) has been marked by the development of closed-chest cardiac massage, art if icial respiration, and electrical defibri l lation into a practical set of techniques for the treatment of patients in cardiac arrest. After i ts introduction in 1960, closed-chest CPR was shown to be successful in resuscitating approximately 25% of...
متن کاملCerebral blood flow in humans following resuscitation from cardiac arrest.
Cerebral blood flow was measured by xenon-133 washout in 13 patients 6-46 hours after being resuscitated from cardiac arrest. Patients regaining consciousness had relatively normal cerebral blood flow before regaining consciousness, but all patients who died without regaining consciousness had increased cerebral blood flow that appeared within 24 hours after resuscitation (except in one patient...

Association between arterial hyperoxia following resuscitation from cardiac arrest and in-hospital mortality.
CONTEXT Laboratory investigations suggest that exposure to hyperoxia after resuscitation from cardiac arrest may worsen anoxic brain injury; however, clinical data are lacking. OBJECTIVE To test the hypothesis that postresuscitation hyperoxia is associated with increased mortality. DESIGN, SETTING, AND PATIENTS Multicenter cohort study using the Project IMPACT critical care database of inte...
