改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值

目的探讨改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值。方法回顾45例输卵管阻塞性不孕患者,应用常规法行介入再通术,其中输卵管开口插管失败采用改良双腔球囊导管行介入再通,统计分析常规法组与联合改良双腔球囊导管法组(联合法组)的输卵管开口插管成功率、输卵管阻塞的开通率。结果输卵管阻塞性不孕患者45例,共阻塞输卵管90条,采用常规法输卵管开口插管成功32条,其中开通成功31条,插管成功率为35.56%,开通率96.88%。采用联合法输卵管开口插管成功90条,输卵管开通83条,插管成功率为100%,开通率92.22%,7条输卵管因阻塞病情严重无法开通,其中双侧均未能开通1例。所有患者术中均无严重并发症发生。随访12个月,妊娠率48.65%。常规法组与联合法组输卵管开口插管成功率差异具有统计学意义(χ^2=85.574,P=0.000),而输卵管开通率差异无统计学意义(χ^2=0.248,P=0.619)。结论对于常规法输卵管开口插管失败者,采用联合改良双腔球囊导管可提高输卵管开口插管成功率。采用改良双腔球囊导管介入再通与常规法开通效果相当,可作为常规介入再通输卵管开口插管失败的备选方案。     

一次性根管与常规根管治疗后冠修复对隐裂性牙髓炎患者的影响

目的 探讨一次性根管与常规根管治疗后冠修复对隐裂性牙髓炎患者的治疗效果。方法 选取2014年5月至2017年5月诊治的187例隐裂性牙髓炎患者随机分为观察组和对照组,观察组给予一次性根管治疗后冠修复,对照组给予常规根管治疗后冠修复,比较两组术前及术后1周Mohd Sulong疼痛分级、术后3个月临床疗效、术后6个月X线改变、术后2年治疗成功率。结果 术前两组Mohd Sulong疼痛分级无统计学差异(P＞0.05),冠修复术后1周两组疼痛分级无统计学差异(P＞0.05),术后3个月观察组临床疗效总有效率为97.83%较对照组88.41%显著提高(P＜0.05),术后6个月观察X线改变率为3.26%较对照组14.74%显著降低(P＜0.05),术后2年观察组治疗成功率为94.57%较对照组82.11%显著提高(P＜0.05)。结论 一次性根管治疗后冠修复能够缓解隐裂性牙髓炎疼痛,提高临床疗效,提高患者咀嚼功能和生活质量,值得在临床上推广。     

一次性湿热交换器在新生儿机械通气长途转运中应用的效果分析

目的探讨研究一次性湿热交换器在新生儿机械通气长途转运中应用的临床意义。方法 2017年1月-2017年12月,我院120转运中心长途转运接收786例机械通气新生儿,786例患儿随机分为常规气道护理(对照组)和转运途中应用一次性湿热交换器组(治疗组),对比转运过程中的吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率。结果研究数据显示治疗组吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率有显著性差异(P<0.05)明显低于对照组。结论在机械通气新生儿长途转运中,一次性湿热交换器的可减少转运患儿吸痰次数发生率、降低肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率具有明显优越性,值得推广。     

气雾熏蒸法与浸泡消毒法消毒吸痰管效果比较

目的比较2%强化戊二醛(下称戊二醛)气雾熏蒸法与浸泡消毒法消毒吸痰管的效果.方法消毒按5周期(1个周期12 d)进行,每周期将200根使用过的吸痰管经初步处理,即5% 84消毒液浸泡30 min后清水冲洗干净晾干.将每周期200根吸氮管随机均分为实验组和对照组,实验组采用戊二醛原液气雾熏蒸法消毒4 h,对照组采用戊二醛原液浸泡消毒30 min,12 d为1个周期.两组分别于第1、6、12天对消毒后的吸痰管及消毒过程中的戊二醛采样行细菌菌落数计数,并观察有无细菌生长.结果两组每周期第1、6天吸痰管和消毒液标本均未检测出细菌,且无致病微生物生长;每周期第12天对照组吸痰管和消毒液标本均检测出细菌,实验组未检测出细菌.结论气雾熏蒸法消毒灭菌效果可靠,具有节约开支、使用方便、有利于吸痰管的保存与放置等优点.     

IMPROVED BALLOON‐TIPPED TRANS‐ANAL ILEUS TUBE

Background: For management of bowel obstruction due to colorectal cancer, endoscopic trans‐anal decompression technique has been first reported by Lelcuk et al. in 1986 using balloon dilatation technique. Since then, various types of trans‐anal decompression tubes have been clinically used for patients suffering from left side obstructing colorectal cancer as an emergent decompressing device. At present, two types of trans‐anal ileus tube (trans‐anal decompression tube) have been available for clinical use, but they have two main problems that are late colon perforations caused by the tip of the tube and tube obstruction by stool. Methods: Analysis on three late colon perforations experienced with the use of conventional devices drew possible improvements to make a trans‐anal ileus tube less harmful. To overcome the pitfalls inherent to conventional tubes, the author has developed an improved trans‐anal ileus tube with a balloon installed at the very end of the tube (‘balloon‐tipped type’) made of silicone, measuring 1200 or 1700 mm in total length and 22 Fr in outer diameter. It has been used for 12 cases with obstructing colorectal cancer etc. and its outcomes were compared with those obtained by the use of conventional trans‐anal ileus tube. Results: No late perforations have been encountered, but tube obstruction did occur in one of 12 cases. Conclusion: The new trans‐anal ileus tube with a balloon installed at the tip of ileus tube is considered to be safer and especially effective in preventing late colon perforation and tube obstruction.

Iniencephaly and long-term survival: a rare case report

Introduction Iniencephaly, a neural tube defect involving occiput and inion and combined with rachischisis of the cervical, thoracic spine, and retroflexion position of the head is a very rare congenital abnormality of the fetus–newborn with a 0.1–10 of 10,000 prevalence. This abnormality’s prognosis is thought to be dismal. This abnormality can be associated with other abnormalities such as anencephaly, encephalocele, hydrocephalus, cyclopia, absence of the mandible, cleft lip and palate, cardiovascular disorders, diaphragmatic hernia, renal abnormalities, overgrowth of the arms compared to the legs, and club food and gastrointestinal atresia. Discussion Most of the patients are dead born, and the others die in a few hours. There are only six previously documented long-term survivors. In our case, our patient with iniencephalic signs and findings is still living. She is 2 years old now. We think that this patient presents a mild form of iniencephaly.     

Thyroid Artery Erosion by Esophageal Cancer: Management with Interventional Radiology

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel.     

鼻胃管胃肠减压在择期腹部手术中的应用价值

鼻胃管胃肠减压曾被常规应用于择期和急诊的腹部手术后，目的是预防急性胃扩张的发生、治疗梗阻、降低吻合口压力等。但是，鼻胃管置入也会带来一些副作用，如呼吸道并发症、胃-食道反流、体液和电解质的丢失、声带的损伤，以及越来越被重视的患者的不适感。近年来的研究结果也对择期的腹部手术后常规应用鼻胃管胃肠减压提出不同的看法。现重新评价应用鼻胃管胃肠减压的理论基础及相关临床研究的结果，并对鼻胃管胃肠减压在择期腹部手术中的价值作一综述。
