Anesthetic management of patient with hypertrophic cardiomyopathy and automatic implantable cardioverter defibrillator with a hand fracture

引用

World Journal of Anesthesiology 2013年第1期2卷 8-10页

作者： jaime ortiz Department of Anesthesiology Baylor College of Medicine Houston TX 77025 United States

A 26-year-old male with a history of hypertrophic cardiomyopathy(HCM) and ventricular arrhythmias s/p automatic implantable cardioverter defibrillator(AICD) placement presented for open reduction and internal fixation of an open third metacarpal fracture and extensor tendon repair. He underwent successful surgery after placement of an ultrasound-guided infraclavicular brachial plexus block with ropivacaine 0.5% as the main anesthetic. This case report discusses the anesthetic management of patients with HCM and AICD, different approaches available for brachial plexus blockade, and potential complications of anesthesia and surgery in this group of patients.

Management of a patient with perioperative saddle embolus

World Journal of Anesthesiology 2013年第1期2卷 11-13页

作者： Austin Lee jaime ortiz Department of Anesthesiology Baylor College of Medicine Houston TX 77030 United States

Pulmonary embolism is a major cause of morbidity and mortality. Risk factors include venous stasis, endothelial injury, and hypercoagulability. Prevention centers on the use of sequential compression devices and anticoagulation in the hospital patient. This is the case of a 45-year-old male who presented for open reduction and internal fixation of tibia plateau fracture. He developed a saddle embolus during the perioperative period which was diagnosed in the recovery room after workup for the cause of his poor oxygenation. A chest computed tomographic scan showed an extensive saddle embolus with partial occlusion of the bilateral main pulmonary arteries and all segmental pulmonary artery branches. This case report discusses his diagnosis, management and clinical course. In addition, risk factors, treatment and prevention for pulmonary embolus and described.

In the present work the synthesis of C60 produced in a conventional microwave oven from the decomposition of camphor resin is reported. The polycrystalline structure of the sample was determined by X-Ray Diffraction (XRD), the sample showed several phases, the main phase corresponds to fullerene C60 ordered in a Face-Centered Cubic structure (FCC), with two more structures: one orthorhombic system and the other the monoclinic system coexisting also with graphite 2H phase. It was observed in a Scanning Electron Microscopy (SEM), that the sample formed thin films of stacked carbon. Whereas in a High Resolution Transmission Electron Microscopy (HRTEM), measurements in Bright Field mode revealed that the main phase of the material is C60 ordered in FCC structure and the elemental composition and atomic bonding state can be determined by analyzing the energy with the electron microscope by Elesctron Energy- Loss Spectroscopy (EELS), technique allowed confirm all the phase C60 established with XRD observations.

New approach to assess sperm DNA fragmentation dynamics： Fine-tuning mathematical models

Background： Sperm DNA fragmentation（sDF） has been proved to be an important parameter in order to predict in vitro the potential fertility of a semen sample. Colloid centrifugation could be a suitable technique to select those donkey sperm more resistant to DNA fragmentation after thawing. Previous studies have shown that to elucidate the latent damage of the DNA molecule, sDF should be assessed dynamically, where the rate of fragmentation between treatments indicates how resistant the DNA is to iatrogenic damage. The rate of fragmentation is calculated using the slope of a linear regression equation. However, it has not been studied if s DF dynamics fit this model. The objectives of this study were to evaluate the effect of different after-thawing centrifugation protocols on sperm DNA fragmentation and elucidate the most accurate mathematical model（linear regression, exponential or polynomial） for DNA fragmentation over time in frozen-thawed donkey ***： After submitting post-thaw semen samples to no centrifugation（UDC）, sperm washing（SW） or single layer centrifugation（SLC） protocols, sD F values after 6 h of incubation were significantly lower in SLC samples than in SW or *** of determination（R-2） values were significantly higher for a second order polynomial model than for linear or exponential. The highest values for acceleration of fragmentation（aSDF） were obtained for SW, fol owed by SLC and ***： SLC after thawing seems to preserve longer DNA longevity in comparison to UDC and SW. Moreover,the fine-tuning of models has shown that sDF dynamics in frozen-thawed donkey semen fit a second order polynomial model, which implies that fragmentation rate is not constant and fragmentation acceleration must be taken into account to elucidate hidden damage in the DNA molecule.

＜正＞ Multiple alphal-adrenoceptors seem to contract rat tail artery. AlphalA- predominates and either alpha1B-,alpha1D-,or alpha1L-is the second population. We characterized alphal-adrenoceptors with selective agonists/antagonists in tail artery of young Wistar rat. Tail artery was exposed to A61603 （N-[5-（4.5- dihy-dro- 1H- imidazol - 2 - yl） - 2 - hydroxy - 5. 6. 7. 8 - tetrahydronaphthalen- 1 - yl] methanesulfonamide） or to phenylephrine （alphalA- and alphal- agonists ）, and to prazosin （alphal- antagonist）, the alphal A-antagonists 5 - methy-lurapidil,RS 100329 （5-methyl - 3 - [3 - [4 - [2 - （2,2,2,-trifluoroethoxy） phenyl] - 1-piperazinyl] propyl] - 2,4-（1H）-pyrimidinedione）,RS 17053 （N- [2（2-cyclopropylmethoxy） ethyl] - 5-chloro-a, a-dimethyl - 1H-indole - 3-ethylamine）, and the alpha1D-antagonist BMY 7378 （8-[2-[4-（2-methoxyphenyl） - 1-piperazinyl] ethyl] - 8 - azaspiro[4.5] decane - 7,9 -dione） . A61603 showed 100 fold higher affinity over PHE. Prazosin,RS100329,5-MU,and RS17053 displaced agonists with high affinity indicating alphal A-adrenoceptors while PHE activated alphal B-adrenoceptors since BMY 7378 had low affinity.
