Insights
Therapeutic hypothermia (TH) for sudden cardiac arrest (SCA) survivors showed improved glycemic control with a specific insulin protocol. This approach reduced blood glucose alterations during TH stages, with low hypoglycemia rates.
Area of Science:
- Cardiology
- Intensive Care Medicine
- Endocrinology
Context:
- Therapeutic hypothermia (TH) is a critical intervention for sudden cardiac arrest (SCA) survivors.
- Glycemic control in patients undergoing TH is not well-established.
- This study investigates glycemic management during TH.
Purpose:
- To evaluate the effectiveness of a specific insulin protocol for glycemic control in SCA survivors treated with TH.
- To analyze glycemic levels across different stages of TH (induction, maintenance, rewarming).
Summary:
- A retrospective analysis of 49 SCA survivors treated with TH and a specific insulin protocol was conducted.
- High rates of glycemic alteration were observed during the induction stage, decreasing significantly by the rewarming stage (95.9% to 69.4%).
- The protocol resulted in low rates of severe hypoglycemia (12%), in-hospital mortality (20%), and anoxic encephalopathy (27%).
Impact:
- The findings suggest that a dedicated insulin protocol can improve blood glucose management in patients undergoing TH.
- Further research is warranted to confirm the clinical impact of such protocols on patient outcomes.
- This study provides valuable insights for optimizing care protocols in post-SCA management.
Objective:
Therapeutic hypothermia (TH) is recommended to improve survival and neurologic prognosis in sudden cardiac arrest (SCA) survivors. There are few data aboutglycemic levels in these patients. The aim of this study is to evaluate the glycemic control using a specific protocol in this group ofpeople.
Method:
A retrospective analysis of the patients receiving TH in our institution, between January 2010 and March 2013,. was performed. Baseline characteristics, in-hospital prognosis and glycemic levels during different stages of the TH were analyzed.
Results:
From a total of 55 patients suffering a SCA, 49 patients underwent TH and received a specific insulin protocol. The mean age was 57.5 ± 12.8 years, the main cause of SCA was ischemic (76%) and ventricular fibrillation was the most frequent first rhythm detected (55%). Regarding glycemic alterations as each stage of TH, a high rate of glycemic alteration was observed in the induction stage, decreasing after starting the insulin protocol (induction stage: 95.9%; maintenance stage: 89.8%; rewarming stage: 69.4%; p = 0.001). With respectto clinicresults, there were low rates of severe hypoglycemia (12%), in-hospital mortality (20%) and anoxic encephalopathy (27%), with a high rate of infections (75%).
Conclusions:
The implementation of a specific insulin protocol in patients receiving TH contributes to improve the blood glucose levels. Further studies are needed to evaluate the clinical impact of these protocols in this group ofpatients.
