  • 气管插管固定器在中毒洗胃中的应用

    目的研究在洗胃过程中应用气管插管固定器固定胃管的可行性。 方法将2014年1月-2015年1月就诊的急性中毒需要洗胃的80例患者随机分为研究组和对照组,每组各40例。研究组洗胃采用气管插管固定器固定胃管,对照组采用传统手持牙垫固定,观察比较两种固定方法的稳妥性、安全性、口腔损伤例数、意外拔管率。计数资料采用χ2检验进行分析。 结果研究组的固定性(97.5%)、方便性(90.0%)均优于对照组(分别为22.5%、20.0%),恶心发生率(5.0%)、呕吐发生率(5.0%)、咽喉部刺激反应发生率(25.0%)和并发症发生率(12.5%)均低于对照组(分别为72.5%、65.0%、85.0%、40.0%),差异均有统计学意义(P<0.05)。两组一人独立操作性、一次性插管成功率、堵管率、胃管脱出率、辅助器材使用率比较,差异无统计学意义(P>0.05)。 结论在洗胃中使用气管插管固定器固定胃管优于传统固定方式,值得在临床推广应用。

  • A BIOMECHANICAL STUDY OF STABILITY OF ATLANTOAXIAL JUNCTION FIXATION WITH ANTERIORAPPROACH SCREW FIXATION THROUGH C2 VERTEBRAL BODY TO C1 LATERAL MASS AND GALLIE’STECHNIQUE

    【Abstract】 Objective To determine the three-dimensional stabil ity of atlantoaxial reconstruction withanterior approach screw fixation through C2 vertebral body to C1 lateral mass and Gall ie’s technique (ASMG) for C1,2instabil ity. Methods Twenty-five human cadaveric specimens (C0-3 ) were divided randomly into 5 groups (n=5). Thethree-dimensional ranges of motion C1 relative to C2 were measured under the five different conditions:the intact state group (group A), type II odontoid fracture group (group B), posterior C1,2 transarticular screw fixation group (group C), ASM group (group D) and ASMG group (group E). The three-dimensional ranges of motions C1 relative to C2 by loading ± 1.5 Nm were measured under the six conditions of flexion/extension, left/right lateral bending, and left/right axial rotation. The obtained data was statistically analyzed. Results In each group, the three-dimensional ranges of motion C1 relative to C2 under the six conditions of flexion/extension, left/right lateral bending, and left/right axial rotation were as follows: in group A (8.10 ± 1.08), (8.49 ± 0.82), (4.79 ± 0.47), (4.93 ± 0.34), (28.20 ± 0.64), (29.30 ± 0.84)°; in group B (13.60 ± 1.25), (13.80 ± 0.77), (9.64 ± 0.53), (9.23 ± 0.41), (34.90 ± 0.93), (34.90 ± 1.30)°; in group C (1.62 ± 0.10), (1.90 ± 0.34), (1.25 ± 0.13), (1.37 ± 0.28), (0.97 ± 0.14), (1.01 ± 0.17)°; in group D (2.03 ± 0.26), (2.34 ± 0.49), (1.54 ± 0.22), (1.53 ± 0.30), (0.80 ± 0.35), (0.76 ± 0.30)°; in group E (0.35 ± 0.12), (0.56 ± 0.34), (0.44 ± 0.15), (0.55 ± 0.16), (0.43 ± 0.07), (0.29 ± 0.06)°. Under the six conditions, there were generally significant differences between group A and other four groups, and between group B and groups C, D and E (P lt; 0.001), and between group E and groups C, D in flexion/ extension and left/right lateral bending (P lt; 0.05). There was no significant difference between group E and groups C, D in left/right axial rotation (P gt; 0.05). Conclusion In vivo biomechanical studies show that ASMG operation has unique superiority in the reconstruction of the atlantoaxial stabil ity, especially in controll ing stabil ity of flexion/extension and left/right lateral bending, and thus it ensures successful fusion of the implanted bone. It is arel iable surgical choice for the treatment of the obsolete instabil ity or dislocation of C1, 2 joint.

  • Clinical application of nitinol memory alloy two foot fixator combined with Kirschner wire in treatment of trans-scaphoid perilunate dislocation

    ObjectiveTo evaluate the effectiveness of nitinol memory alloy two foot fixator combined with Kirschner wire in the treatment of trans-scaphoid perilunate dislocation.MethodsBetween September 2011 and October 2018, 17 patients with trans-scaphoid perilunate dislocation were treated with nitinol memory alloy two foot fixator and Kirschner wire. There were 12 males and 5 females, with an average age of 32.6 years (range, 23-52 years). The disease duration was 8 hours to 9 days, with an average of 6.5 days. The causes of injury included 6 cases of falling injury, 4 cases of traffic accident injury, 3 cases of stress injury of wrist caused by sports, 2 cases of violent injury of wrist caused by machine impact, 1 case of military training injury, and 1 case of other injury. One case was complicated with nerve injury. According to Herbert’s classification, all the fractures were type B4. At 1 week before operation, 3 months, 6 months after operation and last follow-up, the wrist function was evaluated according to the Krimmer scale score.ResultsAll the 17 patients were followed up 10.5-48 months, with an average of 18.6 months. There was no loosening or infection of the internal fixator, no necrosis of the scaphoid and lunate. The periosteal dislocations of the patients were well reduced and the scaphoid fractures all healed. The healing time was 4-18 months, with an average of 11.3 months. The Krimmer wrist scores were 37.5±4.4, 61.3±7.2, 83.3±9.3, 87.3±8.2 at 1 week before operation, 3 months, 6 months after operation and last follow-up, respectively. The Krimmer wrist score at each time point after operation was significantly improved when compared with that before operation (P<0.05), and at 6 months after operation and last follow-up than at 3 months after operation (P<0.05). There was no significant difference between at 6 months and last follow-up (P>0.05). At last follow-up, the Krimmer wrist function was excellent in 13 cases, good in 2 cases, fair in 1 case, poor in 1 case, and the excellent and good rate was 88.23%.ConclusionNitinol memory alloy two foot fixator combined with Kirschner wire in the treatment of trans-scaphoid periosteal dislocation has definite effectiveness, simple operation, and good recovery of wrist function after operation.

  • PRELIMINARY APPLICATION OF THREE-DIMENSIONAL PRINTING PERSONALIZED EXTERNAL FIXATOR IN SERIOUS TIBIOFIBULA FRACTURES

    ObjectiveTo explore a new method of treating serious tibiofibula comminuted fracture by using three-dimensional (3-D) printing personalized external fixator. MethodsIn April 2015, a male patient (aged 18 years with a height of 171 cm and a weight of 67 kg) with left tibiofibula comminuted fracture was included in the study. Computer-assisted reduction technique combined with 3-D printing was used to develop a customised personalized external fixator for fracture reduction. The effectiveness was observed. ResultsThe operation time was about 10 minutes without fluoroscopy, and successful reduction was obtained. The patient had equal limb length after operation. X-ray films showed that the posterior angulation of distal fracture was corrected 37°, and the eversion angle was corrected 4°. The tibial fractures had good paraposition or alignment, and the lower limb force line was corrected completely. No new fracture displacement occurred. The clinical healing time of fracture was 3.5 months and the bone union was achieved after 8 months. The function of affected limb recovered well after operation. ConclusionA personalized external fixator for serious tibiofibula comminuted fracture reduction made by 3-D printing technique has the merits of easy manipulation, high individuation, accurate reduction, stable fixation, and no need of fluoroscopy.
