Fifty-one patients (60.2 卤 14.2 years, 42 males and 9 females) who experienced cardiogenic cardiac arrest, including both shockable and non-shockable cardiac arrest, were enrolled in this study. Forty patients were treated with TH using the Arctic Sun 2000庐 for surface cooling, while the other 11 patients were treated with TH using conventional standard cooling blankets. The patients鈥?clinical courses during TH and the neurological outcomes were compared between the two groups.
The body temperature before TH was not significantly different between the two groups; however, the minimal body temperature during TH was significantly lower in the patients cooled with conventional standard blankets than in those cooled using the Arctic Sun 2000庐. The rates of catecholamine administration, left ventricular ejection fraction, and mechanical support were not significantly different between the two groups; however, the maximum infusion dose of dobutamine was significantly lower in the patients with the Arctic Sun 2000庐 than in those treated with standard cooling blankets.
The use of TH with the Arctic Sun 2000庐 following cardiac arrest is safe and effective in precisely maintaining the target body temperature, and can be used to reduce the infusion dose of dobutamine to treat heart failure during TH.
