电视硬质气管镜治疗大气道良性肿瘤

目的探讨电视硬质气管镜在大气道良性肿瘤治疗中的价值.方法2002年9月～2005年4月,我院应用电视硬质气管镜治疗大气道良性肿瘤7例,其中气管1例,隆突1例,左主支气管3例,右主支气管2例.手术采用静脉全身麻醉,喷射通气供氧,探查评估气道后,首先冷冻或电凝肿瘤,破坏肿瘤血供,再以活检钳分块取出,蒂部采用冷冻或氩气凝固处理;对于宽蒂肿瘤,内镜下将肿瘤主体清除后中转开胸行气管局部切除吻合术.结果7例手术均顺利,无一例死亡和严重并发症发生.6例气管窄蒂良性肿瘤镜下完整摘除,1例气管膜部宽蒂平滑肌瘤先内镜清除肿瘤主体后中转开胸行气管局部切除.术后病理为错构瘤2例,平滑肌瘤3例,嗜酸性肉芽肿性腺瘤1例,炎症组织1例.7例随访3～36个月,平均17.3月,无肿瘤复发.结论电视硬质气管镜治疗大气道良性肿瘤安全可靠.     

Ilizarov技术矫正儿童僵硬型马蹄内翻足畸形

[目的]探讨Ilizarov技术矫正僵硬性马蹄内翻足畸形的方法和效果。[方法]作者在2000年3月～2005年3月间，使用Ilizarov技术矫正9例11足重度僵硬性马蹄内翻足畸形，将连接于胫骨、跟骨、跖骨的外固定环互相连接、组合成复杂的三维外固定架，通过逐渐调整外固定架矫正畸形，从而使患足达到或接近正常足的外形和功能。[结果]按Garceau标准评定疗效，优6足，良4足，差1足。[结论]Ilizarov外固定架三维矫正马蹄内翻足畸形效果确实，尤其适用于大年龄儿童之僵硬、复发或难治性马蹄内翻足，有一定的临床应用价值。     

Measurement of axial edge lift of rigid corneal lenses*

A simple but reliable method was used to measure the axial edge lift at the total diameter over a range of back optic zone radii of several proprietary designs of rigid gas-permeable corneal lens. One of these was found to have a constant axial edge lift construction.     

Flexible versus rigid endoscopes for outpatient hysteroscopy: a prospective randomized clinical trial

To evaluate patient acceptance, optical properties and the clinical feasibility of flexible compared with rigid hysteroscopes, 142 patients undergoing outpatient hysteroscopy were included in a prospective, randomized clinical trial. The flexible hysteroscope was used in 70 patients, and the rigid instrument in 72. At different stages of the hysteroscopy the level of pain experienced by the women was assessed using a 10 cm visual analogue scale. Optical properties characterized by the parameters intrauterine visibility, hysteroscopic view and diagnostic accuracy were ranked by the surgeons using a 5-point scale (1 = excellent to 5 = insufficient), and duration of the hysteroscopy was measured. Hysteroscopy was successful in 87.5 and 100% of patients in the flexible and rigid groups respectively. With the use of rigid telescopes, discomfort at introduction and during the hysteroscopy was significantly greater (median 1.7 versus 0.7, P = 0.003; 3.1 versus 1.2, P < 0.001 respectively), but optical properties were judged to be far superior (P < 0.001 for all three comparisons) and procedure time was significantly shorter (median 70 versus 120 s, P = 0.003). In conclusion, outpatient hysteroscopy seems to be less painful when using flexible telescopes. However, rigid hysteroscopes provide superior optical qualities and permit a more rapid performance with higher success rates at much lower cost.

光导纤维支气管镜经口和经鼻气管插管患儿心血管反应的比较

目的比较小儿光导纤维支气管镜(FOB)经口和经鼻气管插管的心血管反应。方法选择美国麻醉医师协会(ASA)身体状态分级为Ⅰ级、在全身麻醉下施择期整形外科手术的患儿65例,随机分为经口组(n=36)和经鼻组(n=29)。在常规静脉麻醉诱导后实施FOB气管插管。测定麻醉诱导前(基础值)、后,气管插管时和气管插管后5 min内(测定间隔为1 min)血压(BP)和心率(HR),记录气管插管时间。结果经鼻组气管插管时间显著长于经口组(P<0.05)。FOB气管插管导致两组BP和HR均比麻醉诱导前基础值显著升高(P均<0.05)。与经口组相比,气管插管致BP增高和HR增快反应在经鼻组较轻,持续时间较短。经口组气管插管时BP和HR及观察过程中BP和HR最大值均显著高于经鼻组(P均<0.05)。结论FOB经口和经鼻气管插管均可引起小儿BP和HR显著升高,但FOB经鼻气管插管时心血管反应较FOB经口气管插管时轻。
