腹腔镜胰腺外科的应用解剖   总被引:1,自引:1,他引:0  
腹腔镜手术效果与开腹手术相比,其优势不容置疑。迄今为止,在微创外科中,腹腔镜技术的应用最为普及,效果最好。然而,由于胰腺位置深在,毗邻关系复杂,给手术带来很大的难度,成为提高手术质量和普及的瓶颈。同时受手术费用、特殊腹腔镜器械等因素的制约,腹腔镜胰腺手术的开展落后于其他腹腔镜手术,其优势难以充分发挥,  相似文献

<正>目前,我国减重代谢手术的开展规模迅速扩大。代谢手术开展规模的快速扩大得益于其优秀的治疗效果。除了标准的手术操作和正确的手术方式选择以外,规范持续的术后随访指导,也是确保手术治疗效果的重要因素。不能依从术后指导的病人,其减重效果和复胖情况与其他病人存在显著差异[1]。由于减重代谢手术的术式不断更新发展,不同手术的术后并发症情况和注意事项明显不同。目前,  相似文献

Summary In order to find out whether the concentration of bone gla-protein (BGP) is elevated in blood derived directly from bone tissue compared to peripherically sampled blood a peroperative model was used. Blood was collected simultaneously from an armvein and from the osteotomized surface of the bone during total hip replacement in 18 patients Peripheral blood was also collected before the anaesthetic procedure. The anaesthetic and/or the operative procedure slightly decreased the level of BGP in the peripheral blood during this short time interval, but serum BGP was not different in the bone-marrow derived blood and in the peripheral blood taken simultaneously. These data suggest that BGP released from bone into the circulation is rapidly cleared from the marrow and that peripheral serum BGP is a valid index of the bone-derived levels of BGP.  相似文献

Using the rat as an animal model, the elimination kinetics of sevoflurane and halothane from brain, blood, and adipose tissue were compared. Elimination of sevoflurane and halothane from blood and brain was biexponential. The rapid, alpha-elimination rates of sevoflurane from blood and brain were faster than the corresponding rates for halothane. However, the slower beta-elimination rates from brain and blood, as well as the elimination rates from adipose tissue, were similar for both volatile anesthetics. Thus, the potential for residual postoperative impairment from subanesthetic tissue concentrations of halothane and sevoflurane may be similar even though sevoflurane is initially eliminated more rapidly from blood and brain.  相似文献

In 90 patients, to whom blood transfusion was done while the thoracic operation conduction, the blood hemoglobin (Hb) content was analysed. In the patients, to whom intraoperatively the blood preparations transfusion was done, Hb concentration in the blood was lower than in patients with similar blood loss, but who was not blood transfused. While the own blood transfusion conduction, which was reinfused from the pleural cavity, the Hb level lowering was not observed. In 1998, comparing with 1984, the blood transfusion rate had lowered from 14.7 to 4.1% while the intraoperative complications rate lowering. The anastomosis sutures insufficiency occurrence rate had reduced also after reconstructive operations on trachea from 7.6% (in 1978-1987) down to 1.8% (in 1988-1998).  相似文献

We studied the effect of blood transfusions (BT) from different H-2 donors on the induction of suppressor cells (SC) and of MLC inhibitory activity in serum in a drug-unmodified mouse model. Balb/c (H-2d) mice were transfused at weekly intervals with whole blood from donors of three strains using two transfusion protocols. In protocol I, blood was transfused first from C3H/HeJ (C3H) (H-2k), then C57Bl (H-2b), and then SJL (H-2s) strain mice, and in protocol II the order of blood donors was reversed. Spleen cells and serum samples were obtained from the transfused mice one and two weeks after the last BT. In both transfusion protocols, the kinetics of responses of cells from recipient transfused mice to cells from the blood donors in MLC were similar to those of cells from nontransfused mice. The peak responses of cells from transfused mice were consistently lower than those of cells from nontransfused mice. In cell-mixing experiments, radiosensitive SC capable of inhibiting responses of Balb/c mice to cells from all three blood donors in MLC could be demonstrated one week after the last transfusion in both protocols. Two weeks after the last BT, SC were demonstrable only against the first (C3H) blood donor in protocol I, and against all three blood donors in protocol II. Serum obtained one week after transfusion in protocol I inhibited responses of Balb/c mice to stimulator lymphocytes from all three blood donors in MLC. Serum obtained two weeks after BT, however, inhibited responses of recipient mice only to the first blood donor. In contrast, in protocol II, serum obtained both one and two weeks after BT did not cause inhibition of responses of cells from Balb/c mice to blood donor cells in MLC. Similar results were obtained when Balb/c mice were transfused at weekly intervals with whole blood from either C3H or from SJL mice. The data suggest that the induction of SC and/or MLC-inhibitory activity in the serum after BT is dependent on the H-2 type of the first blood donor.  相似文献

[摘要] 目的 对心脏术后床旁血气检测结果的差异性进行分析,提高床旁血气检测管理规范执行的依从性,从而提高结果准确度。方法 选择2018年1月至2月心脏重症监护室363例术后患者作为研究对象,每例患者同一时间分别进行床旁血气分析电解质检测和送检验科进行血液生化、血常规检测,对比使用床旁血气分析仪与检验科生化血常规检测分析这两种方法获得的钠、钾、血糖、细胞压积结果的差异性,并分析不同操作者对检测结果差异性的影响。收取2018年1月至6月六个月的床旁血气检测质量管理评定的评分进行对比。结果 两种检测方法仅血钠及红细胞压积两个结果之间存在差异,具有统计学意义。操作者客观因素中,只有基础学历影响具有统计学意义。床旁血气检测质量管理评定评分由原来的55分上升至93分。结论 通过对床旁血气检测与检验科两种检测方法结果的差异分析,临床据此制定严谨的床旁血气分析管理规范,提高其执行的依从性。  相似文献

In patients heparinized for surgery on the infrarenal aorta, the degree of anticoagulation by heparin of stasis blood (taken from below the aortic clamp) was compared with that obtained in circulating blood taken from a forearm artery. A measurement of activated partial thromboplastin time (APTT) was made on a venous blood sample taken from each patient before 5000 units of heparin was administered intravenously. Further measurements of APTT from static blood and from circulating arterial blood were made at 3, 15, 30, and 60 minutes after heparinization. Samples taken below the aortic clamp showed measurements of APTT lower than those from circulating arterial blood at 15, 30, and 60 minutes (p less than 0.05 paired Wilcoxon rank sum test). Current methods for administering and monitoring heparin may not provide an adequate degree of anticoagulation in static blood during vascular surgery. The consequences, if any, of inadequate anticoagulation in vascular surgery need further study.  相似文献
