A questionnaire was sent to all centres of cardiac surgery in the United Kingdom, enquiring into their current use of hypothermia. Moderate hypothermia without cardiopulmonary bypass and the Drew technique of profound hypothermia are becoming less popular, each technique being used in only two of the 30 centres which replied. Moderate hypothermia as an integral part of the cardiopulmonary bypass is used on occasions in 24 centres. Although some centres use moderate hypothermia out of habit, the main benefits from its use are considered to be the protection afforded to the myocardium and a greater safety margin in the event of technical difficulties. Profound hypothermia, usually induced by means of the pump oxygenator, followed by circulatory arrest is becoming increasingly popular for the correction of complex congenital anomalies in infants.
一份调查问卷被发送到英国所有心脏外科中心，询问它们目前对低温技术的使用情况。不使用体外循环的中度低温以及德鲁深低温技术正变得不那么流行，在回复的30个中心中，每种技术仅在两个中心使用。作为体外循环组成部分的中度低温在24个中心偶尔使用。尽管一些中心出于习惯使用中度低温，但其使用的主要益处被认为是对心肌的保护以及在出现技术困难时更大的安全边际。深低温通常通过泵氧合器诱导，随后进行循环停止，在纠正婴儿复杂先天性畸形方面越来越受欢迎。
