目的：确定硬膜外一次性镇痛法对食管癌病人术后的镇痛效果和减少并发症的意义。方法：９３ 例病人随机分成实验组（ Ｔ 组,５１ 例） 和对照组（ Ｃ 组,４２ 例） , Ｔ 组于手术结束缝合皮肤切口时经硬膜外导管于 Ｔ６ － ７ 水平注射吗啡１ ｍｇ 加１ ％ 普鲁卡因１０ ｍｌ, Ｃ 组用阿片类药物肌肉注射镇痛。结果： Ｔ 组病人术后疼痛明显减轻,各种并发症显著下降。结论：硬膜外一次性镇痛效果确切,操作方便,副作用少,对降低术后心肺并发症很有意义,尤其对年龄大、心肺功能差的病人较适合。     

腭裂术后语音的实验研究

提供一种易被患者接受、无害、科学客观的腭裂术后语音缺陷的诊断方法。方法：随机选择各种腭裂类型的腭裂术后患者４７例,将其语音输入ＫＡＹ７８００语图仪,分析其语音特点和语图表现。结果：腭裂术后语音有３大语音特点和８类语图表现。３大语音特点是残缺、代偿和干扰;８类语图表现是辅音残缺、共振峰残缺、送气代偿、浊化代偿、喉塞代偿、鼻音干扰元音、鼻音干扰辅音和噪音干扰。结论：腭裂术后患者口腔内的能量不足是造成以上语音缺陷的主要原因。     

噪声、振动复合因素对汉语语音清晰度影响的研究

目的 探讨噪声、振动复事因素下生成语音在听觉效果上的变化及变化规律。方法 在安静及信噪比分别为０ｄＢ和－６ｄＢ三种状态下进行清晰度测试,以研究噪声、振动复合因素组、单独噪声组、单独振动组及对照组４个组的语音材料清晰度变化规律。结果 和对照组相比,复合因素作用下语音清晰度有明显降低,检验结果非常显著;和单因素相比,多数情况下有显著性变化。研究还发现,清晰度的降低随听音环境的信噪比的降低而变得严重,当     

Finger bougie method compared with pyloroplasty in the gastric replacement of the esophagus

To elucidate the necessity of pyloroplasty for the gastric tube through the posterior mediastinum in esophageal surgery, gastric emptying and duodenogastric reflux (DGR) were evaluated in 16 cases undergoing an anterior pylorectomy (group P) and in 16 cases treated by the finger bougie method (group F). First, the obstruction and reflux symptoms were examined based on a patient questionnaire using a brief scoring system. The median value of the symptom score showed the patients in P to have more symptoms than those in F; however, the difference was not significant (8.0 vs 6.0). Secondly, the swallowed Tc O₄ ⁻ (85 MBq) was counted using a gamma camera at three sites on the sternal bone in the upright position based on a gastric transit scintigram. Both the descending time of the RI peak and the clearance rates were similar between the two groups. Thirdly, intragastric 24-h pH monitoring was carried out. Antimony pH sensors were anchored 5 and 15 cm below the esophagogastrostomy. We could not find any difference between the two groups in both the % time pH>4 and %time pH>7. These findings thus revealed no big difference between groups P and F. The finger bougie method to drain the vagotomized posterior mediastinal stomach was found to achieve results similar to conventional pyloroplasty, while it was also simpler and safer.     

Successful treatment of tracheomalacia associated with esophageal atresia without a tracheoesophageal fistula by aortopexy: Report of a case

Tracheomalacia (TM) is well known as a complication associated with esophageal atresia (EA) and tracheoesophageal fistula (TEF); however, the occurrence of TM requiring surgical treatment in a patient having EA without a tracheoesophageal fistula has never been reported. We describe herein a rare case of TM associated with EA without TEF. Respiratory distress was caused by compression of the trachea by a severely dilated upper esophageal pouch with weakness of the tracheal wall. Aortopexy was performed, and an excellent postoperative result was achieved.     

电化学疗法治疗中晚期食管癌和贲门癌42例

目的探讨应用电化学疗法治疗中晚期食管癌和贲门癌的临床疗效。方法电化学疗法治疗中晚期食管癌和贲门癌４２例,对其治疗前后的疗效进行比较。结果通过对比电化学治疗前后食管Ｘ线钡餐检查及进食改善情况显示,８８％的患者在接受电化学治疗后进食明显改善,８９％的患者食管狭窄扩大在０．５ｃｍ以上。结论电化学疗法治疗食管癌和贲门癌解除食管梗阻见效快,疗效显著,能恢复患者饮食,可为实施其他治疗创造条件,使其远期生存率提高。     

Swallowing,speech, and brainstem auditory-evoked potentials in spasmodic torticollis

To explore the controversial brainstem theory of spasmodic torticollis, eight consecutively referred patients were examined. Three independent examinations were conducted on the same day: a videofluoroscopic barium swallowing examination, an instrumental speech examination, and a brainstem auditory-evoked potential (BAEP) analysis. Swallowing was normal in two patients; speech physiology, in five; and BAEPs, in all. Normal BAEPs refute the brainstem theory, while abnormalities of speech and swallowing temper this conclusion. Several alternative explanations are proposed.The authors have no commercial or proprietary interest in any product mentioned in this article.

Esophageal pressure and apnea hypopnea index in sleep-disordered breathing

Severity of negative esophageal pressure (Pes) and apnea hypopnea index (AHI) were investigated in six cases of upper airway resistance syndrome (UARS) and 11 cases of obstructive sleep apnea syndrome (OSAS). The severity of negative Pes was represented by the highest peak (Pes Max) and the number of increased episodes (more than 13.5 cmH2O) per h (NPesI13.5). There was no significant correlation between Pes indices and AHI. Pes Max and NPesI13.5 were not different among severe OSAS (AHI > 30), mild OSAS (AHI < 30) and UARS. Apnea hypopnea index failed to represent the severity of negative Pes, which is an important aspect of the pathophysiology of sleep-disordered breathing.
