    In this article, we discuss the emerging role of lung point-of-care ultrasonography for regional anesthesiologists and pain management specialists. Lung ultrasonography is a well-established clinical tool that is used on a routine basis in emergency rooms and critical care units internationally to evaluate patients with respiratory distress; however, its benefits to the regional anesthesiologist and pain specialist are not as well known and are practiced less frequently. This review article covers the clinical evidence in support of lung point-of-care ultrasonography as a rapid and superior tool to traditional imaging modalities such as chest radiography and fluoroscopy. As anesthesiologists routinely perform nerve blocks that put patients at potential risk of complications such as pneumothorax or diaphragmatic paresis, it is important to understand how to use lung ultrasonography to evaluate for these conditions, as well as to differentiate between other potential causes of respiratory distress, such as interstitial syndrome and pleural effusions. This article describes the normal and pathological findings that can be used to quickly and confidently evaluate a patient for these conditions.

  • Prilocaine spinal anesthesia for ambulatory surgery: A review of the available studies ANAESTHESIA CRITICAL CARE & PAIN MEDICINE Boublik, J., Gupta, R., Bhar, S., Atchabahian, A. 2016; 35 (6): 417-421


    Transient neurologic symptoms (TNS) led to the abandonment of intrathecal lidocaine. We reviewed the published literature for information about the duration of action and side effects of intrathecal prilocaine, which has been recently reintroduced in Europe. Medline and EMBASE databases were searched for the time period from 1966 to 2015. Fourteen prospective and one retrospective study were retrieved. The duration of the surgical block can be adjusted using doses between 40 and 80mg. Hyperbaric prilocaine in doses as low as 10mg can be used for perianal procedures. Four cases of TNS in 486 patients were reported in prospective studies, and none in 5000 cases in a retrospective data set. Spinal prilocaine appears to be safe and reliable for day case anesthesia. However, as chloroprocaine has a shorter duration and a lower risk of TNS and urinary retention, the indications for prilocaine remain to be defined.

  • Bioartiticial grafts for transmural myocardial restoration: a new cardiovascular tissue culture concept (Retracted article. See vol. 40, pg. 1555, 2011) EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY Kofidis, T., Lenz, A., Boublik, J., Akhyari, P., Wachsmann, B., Stahl, K. M., Haverich, A., Leyh, R. G. 2003; 24 (6): 906-911


    Survival of bioartificial grafts that are destined to restore cardiac function stands and falls with their nutrient supply. Engineering of myocardial tissue is limited because of lack of vascularization. We introduce a new concept to obtain bioartificial myocardial grafts in which perfusion by a macroscopic core vessel is simulated.We have designed an experimental reactor with multiple chambers for the production of bioartificial tissue or tissue precursors. By introduction of in- and output lines of distinct diameter and insertion of a core vessel into each chamber, we established pulsatile, continuous flow through the embodied three-dimensional tissue culture. In the present study, collagen components served as the ground matrix wherein neonatal rat cardiomyocytes were inoculated. For the assessment of cellular viability and distribution in comparison to static, non-perfused culture, fluor-desoxy-glucose-positron-emission-tomography and life/dead assays were employed.We obtained 3D constructs of 8-mm thickness, which display high viability and metabolism (6.0+/-1.3(e-03) in the perfused vs. 4.0+/-0.3(e-03) in the unperfused chambers). The core vessel has the size of a human coronary and remained patent during the entire culture process. We observed centripetal migration of the embedded cardiomyocytes to the site of the core vessel. Cardiomyocytes partially resumed a spindle like form without additional stretch.The present dynamic tissue culture concept is highly effective in manufacturing thick, viable grafts for cardiac muscle restoration, which could be surgically anastomosable. The bioreactor may accommodate multiple types of cells and tissues for innumerable in vitro and in vivo applications.

  • Pulsatile perfusion and cardiomyocyte viability in a solid three-dimensional matrix BIOMATERIALS Kofidis, T., Lenz, A., Boublik, J., Akhyari, P., Wachsmann, B., Mueller-Stahl, K., Hofmann, M., Haverich, A. 2003; 24 (27): 5009-5014


    The manufacture of full thickness three-dimensional myocardial grafts by means of tissue engineering is limited by the impeded cellular viability in unperfused in vitro systems. We introduce a novel concept of pulsatile tissue culture perfusion to promote ubiquitous cellular viability and metabolism.In a novel bioreactor we established pulsatile flow through the embedded three-dimensional tissue culture. Fibrin glue served as the ground matrix wherein neonatal rat cardiomyocytes were inoculated. Fluor-Deoxy-Glucose-Positron-Emission-Tomography (FDG-PET) and life/dead assays were employed for comparative studies of glucose uptake resp. cell viability.A solid 8 mm thick structure resulted. Cellular viability significantly increased in the perfused chambers. We observed centripetal migration of the embedded cardiomyocytes to the site of the core vessel. However, cellular viability was high in the periphery of the tissue block too. FDG-PET revealed enhanced metabolic activity in perfused chambers.The present concept is highly effective in enhancing cellular viability and metabolism in a three-dimensional tissue culture environment. It could be utilized for various co-culture systems and the generation of viable tissue grafts.

  • Clinically established hemostatic scaffold (tissue fleece) as biomatrix in tissue- and organ-engineering research (Retracted article. See vol. 18, pg. 1529, 2012) TISSUE ENGINEERING Kofidis, T., Akhyari, P., Wachsmann, B., Mueller-Stahl, K., Boublik, J., Ruhparwar, A., Mertsching, H., Balsam, L., Robbins, R., Haverich, A. 2003; 9 (3): 517-523


    Various types of three-dimensional matrices have been used as basic scaffolds in myocardial tissue engineering. Many of those are limited by insufficient mechanical function, availability, or biocompatibility. We present a clinically established collagen scaffold for the development of bioartificial myocardial tissue. Neonatal rat cardiomyocytes were seeded into Tissue Fleece (Baxter Deutschland, Heidelberg, Germany). Histological and ultrastructural examinations were performed by DAPI and DiOC(18) staining and electron microscopy, respectively. Force measurements from the spontaneously beating construct were obtained. The constructs were stimulated with agents such as adrenalin and calcium, and by stretching. Passive stretch curves were obtained. Spontaneous contractions of solid bioartificial myocardial tissue (BMT), 20 x 15 x 2 mm, resulted. Contractions continued to week 12 (40% of BMTs) in culture. Histology revealed intercellular and also cell-fibril junctions. Elasticity was similar to that of native rat myocardium. Contractile force increased after topical administration of Ca(2+) and adrenaline. Stretch led to the highest levels of contractile force. In summary, bioartificial myocardial tissue with significant in vitro longevity, spontaneous contractility, and homogeneous cell distribution was produced using Tissue Fleece. Tissue Fleece constitutes an effective scaffold to engineer solid organ structures, which could be used for repair of congenital defects or replacement of diseased tissue.
