摘要
目的比较头后仰侧卧45°和头后仰平卧位麻黄碱滴鼻对高压氧（HBO）治疗时耳痛的影响，确定更为合理的麻黄碱滴鼻方法，为预防耳痛提供参考依据。方法将首次行HBO治疗的患者300例随机分为观察组和对照组各150例，2组患者均采用大型医用空气加压氧舱同舱治疗，HBO治疗的第1～3天进舱前予麻黄碱滴鼻，观察组采用头后仰侧卧45°体位，对照组采用头后仰平卧位，分别在每侧鼻腔内滴1％盐酸麻黄碱滴鼻液3滴，出舱后询问患者有无耳痛，检查鼓膜，并进行比较。结果观察组耳痛、鼓膜损伤发生率和鼓膜损伤程度均低于对照组，2组比较差异明显。结论HBO治疗前采用头后仰侧卧45°麻黄碱滴鼻，可减少HBO时耳痛的发生，该方法滴鼻符合咽鼓管的解剖与生理特点．比头后仰平卧位更合理有效，具有较高的实用价值。
Objective This paper aims to find a best position of ephedrine hydrochloride nasal drops by comparing earache occurred in hyperbaric oxygen（HBO）therapy while using ephedrine hydrochloride nasal drops in two positions： laying in lateral position of 45°with head leaning back; laying down fiat, so as to supply referenee for prevention of earache. Methods We selected 300 eases of HBO patients who were firstly treated by HBO and randomly divided into the observation group and the control group with 150 cases in each group. All these patients were treated by large medical hyperbaric oxygen tank. On the first to third day, ephedrine hydrochloride nasal drops were put into the patients before they were sent into the oxygen tank. Patients in the observation group lay in lateral position of 45°with their head leaning back, and those in the control group were in horizontal position. We put three drops of 1% of ephedrine hydrochloride nasal drops respectively into their nasal cavity. When they came out of the oxygen tank, we asked them if they felt earache and checked their tympanic membrane so as to make a comparison. Results It was found that earache, rate of tympanic membrane injury and the extent of such injury in the observation group was obviously less than that in the control group, there was difference in statistics between these two groups. Conclusions Before HBO treatment, ephedrine hydrochloride nasal drops that put in lateral position of 45°with patients head leaning back can reduce the possibilities of earache occurred in HBO. It was also observed that such position was an ideal one which had anatomical characteristics of Eustachian tube and was safer than laying down flat, so such position is more practical.
