The barriers to utilizing the recommended therapy of hypothermia in post cardiac arrest patients

More evidence is needed to define the optimal duration of hypothermia treatment in humans.

Induced Hypothermia for Patients With Cardiac Arrest

The rate of all-cause death through a mean follow-up of days did not differ between the two groups according to target temperature. He opened his eyes to verbal and tactile stimuli.

AHA: No Gain With Aggressive Cooling After Cardiac Arrest

Outcomes of in-hospital ventricular fibrillation in children. In addition, hypothermia can impair neutrophil and macrophage function, reducing white blood cell count [ 32 ]. A disruption in equilibrium of vaso-active substances such as endothelin, thromboxane A2 TxA2and prostaglandin I2, following an ischemic or traumatic event, can lead to vasoconstriction, hypoperfusion, and thrombogenesis in injured areas of the brain [ 3637 ].

The study included adults mean age 64 who were resuscitated after an out-of-hospital cardiac arrest and remained unconscious. Recent major surgery within 14 days - Hypothermia may increase the risk of infection and bleeding.

The nurses in the unit had 2 full-length body-surface-cooling ice blankets precooling.

Hypothermia and pediatric cardiac arrest

Ischemia-reperfusion also leads to substantial rises in cerebral lactate levels that are shown to be reduced during cooling [ 41 ]. Tajik M, Cardarelli MG. Survival also depends on other factors such as actual duration of CPR, quality of CPR administered and the extent of necessary pharmacologic intervention needed during CPR.

Monitor vital signs and oxygen saturation and place the patient on a continuous cardiac monitor, with particular attention to arrhythmia detection and hypotension. Conversely myocardial contractility decreases when chronotropic agents are administrated or a pacing is placed; if an increase in heart rate is necessary rewarming the patient to a slightly higher temperature may be sufficient.

Several studies showed how hypothermia affects the local secretion of these agents in the brain and in other sites reproducing the natural haemostasis of vasoactive agents [ 38 ]. This alternative temperature probe can be any core temperature monitor eg, esophageal.

Cardiac Arrest and Duration of Hypothermia Therapy

Eur J Cardio-Thorac Surg. His co-authors reported relationships with the Asmund S. Six hours after rewarming started, SB had a core temperature of The overall population-based incidence of non-traumatic pediatric out-of-hospital cardiac arrest is 8 perpediatric person-years compared to peradult patient-years.

Posters were developed that showed the new order set and a list of the journal articles used to develop the protocol. The practitioner should consider the most likely etiology of the cardiac arrest.

With the fall in energy stores, the release of excitatory neurotransmitters such as N-methyl-D-aspartate NMDA [ 23 ] occurs and mitochondrial dysfunction also develops. One large cohort study of cardiac arrest patients found that targeted temperature management TTM was not associated with good outcome in nonshockable patients.

Appropriate attention must be taken in wound care [ 68 ].

Targeted Temperature Management (Therapeutic Hypothermia)

Numerous animal experiments and some clinical studies showed that hypothermia suppresses ischemia-induced inflammatory reactions and release of pro-inflammatory cytokines and decreases the production of nitric oxide, which is a key agent in the development of post-ischemic brain injury [ 31 ].How Low Should We Go?

Hypothermia or Strict Normothermia After Cardiac Arrest? the evidence underpinning use of hypothermia in cardiac arrest patients was subsequently criticized. though still slow by modern standards. Of note, a small pilot study published recently in Circulation randomized post-CA patients to target temperatures of.

Rapid warming is harmful and can negate the benefits of therapeutic hypothermia. 4,5 In addition, were all consecutive patients with cardiac arrest and return of spontaneous circulation screened.

Therapeutic Hypothermia to Improve Survival After Cardiac Arrest in Pediatric Patients-THAPCA-OH [Out of Hospital] Trial (THAPCA-OH) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.

Post cardiac arrest therapeutic hypothermia in adult patients, state of art and practical considerations a recent survey carried out on all UK intensive care units showed that 85% of departments considered TH as a part of post cardiac arrest management with a major medium, or fast re-warming following post-traumatic hypothermia therapy.

Perceived barriers to therapeutic hypothermia for patients resuscitated from cardiac arrest: A qualitative study of emergency department and critical care workers* resuscitatibr care of post cardiac arrest patients?

Probes: Are you aware of the guidelines for TH? Therapeutic Hypothermia After Cardiac Arrest: Best Practices Deborah Klein, RN, MSN, ACNS-BC, CCRN, CHFN, FAHA nonshockable rhythm or cardiac arrest in hospital.

•TH is recommended in combination with primary PCI, comatose post-arrest patients with a TTM goal.
