An analgesic mixture of nitrous oxide and oxygen (Entonox) has been used in nine ambulances in Gloucestershire for self-administration by patients in severe pain. Over a period of three and a half months 66 patients have been treated. In all cases the pain was wholly or partially relieved, and in no instance was the patient's condition worsened. No undesirable side-effects attributable to Entonox were produced. It is recommended that other ambulance authorities should consider the use of Entonox in this context.
一种由一氧化二氮和氧气组成的止痛合剂（安桃乐）已在格洛斯特郡的9辆救护车上供剧痛患者自行使用。在三个半月的时间里，共治疗了66名患者。所有病例的疼痛都得到了全部或部分缓解，且患者的病情均未恶化。未产生任何可归因于安桃乐的不良副作用。建议其他救护部门也考虑在这种情况下使用安桃乐。
