    Experiences with the new inhalational agents in low-flow anesthesia and closed-circuit technique. Monitoring and technical equipment.
    Appl Cardiopulm Pathophysiol 1995 ;5 Suppl 2:47-57
    Institute of Anesthesiology, Technische Universität München, Germany.
    During recent years interest has focused on two completely fluorinated ethers, desflurane and sevoflurane, which promise a shorter induction of and emergence from anesthesia. Their physicochemical properties differ from isoflurane, enflurane and halothane, thus requiring new technical equipment and leading to a change in anesthesiological procedures. Low-flow anesthesia with desflurane can be performed, the technical equipment is available, especially vaporizers and gas analyzers. Read More

    Gas monitoring and uptake.
    Appl Cardiopulm Pathophysiol 1995 ;5 Suppl 2:31-9
    Cattedra di Anestesiologia e Rianimazione, Università degli Studi di Pisa.
    The breath-by-breath monitoring of anesthetic gases can provide information, beyond the usual safety control. The study of the decay and concentration effects along the circuit can be useful to evaluate their kinetics. The presence of unexpected gases coming from the patient's tissues is another important topic. Read More

    Heparin removal in three intraoperative blood savers in cardiac surgery.
    Appl Cardiopulm Pathophysiol 1993 ;5(1):5-8
    Anes. Dept. Cardiovascular surgery, Rangueil Hospital, Toulouse, France.
    The aim of the study was to compare the residual heparin in the composition of autologous blood retransfusion units harvested during cardiac surgery under extra-corporeal circulation with three different intraoperative autologous blood savers. In this institutionally approved study, thirty patients undergoing CABG were randomly assigned to three groups according to the intraoperative blood saver used during the procedure: {HAEMONETICS Cell Saver IV (n=10)--DIDECO/SHILEY STAT (n=11)--BRAT 250 (n=9)}. Anaesthesia and conduct of bypass were identical for all patients. Read More

    Intravascular oxygenation: adjunct in acute respiratory failure.
    Appl Cardiopulm Pathophysiol 1992 ;4(4):287-91
    Department of Cardiothoracic Surgery, Cleveland Clinic Foundation, Ohio 44195.
    The IVOX device represents an early prototype of an intravascular membrane oxygenator that is capable of transferring significant amounts of O 2 and CO 2. It employs new hollow-fiber membrane technology and thromboresistant coatings that should allow the development of a membrane oxygenator that can be placed either intravascularly or ex vivo to provide significant gas exchange without the adverse effects seen in prior ECMO studies including bleeding from heparinization and plasma breakthrough resulting in the gradual deterioration of gas exchange. It may well be that this technology will eventually supplant conventional mechanical ventilation in the support of patients requiring intensive ventilator assistance or in those that are long term weaning problems, thus avoiding the not insignificant problems associated with high intensity and/or long term mechanical ventilation.

    Lung transplantation: state of the art.
    Appl Cardiopulm Pathophysiol 1992 ;4(4):263-71
    Department of Cardiothoracic Surgery, Cleveland Clinic Foundation, Ohio 44195.
    Since the first long term successful single lung transplant in 1983, followed by a successful double lung transplant in 1986, lung transplantation has become established world-wide as an accepted option in the treatment of end-stage respiratory disease of various etiologies. Both procedures carry acceptable morbidity and mortality rates with the actuarial 5 year survivor rate of 80%. Single or double lung transplantation offers many advantages over heart-lung transplantation and is gradually supplanting the latter in most centers with certain exceptions. Read More

    Transfer of 99mTc-DTPA, lung surfactant and lung injury: a review of the literature.
    Appl Cardiopulm Pathophysiol 1991 ;4(2):155-60
    Dept. of Clinical Physiology, University of Lund, Sweden.
    Measurement of the alveolo-capillary transfer of radiolabelled solutes provides information about the integrity of the alveolo-capillary barrier. The transfer of 99mTc-diethylen triamine penta-acetate ( 99mTc-DTPA) can be easily measured after tracer delivery in aerosol form and external monitoring of radiation over the lung. Although the technique has been used extensively for more than ten years, the basic mechanisms for pulmonary clearance of 99mTc-DTPA remain incompletely understood. Read More

    Continuous hemodynamic monitoring: an integrated invasive-noninvasive approach using the Fick principle.
    Appl Cardiopulm Pathophysiol 1991 ;3(4):351-9
    Dept of Surgery, Albany Medical College, New York 12208.
    This paper reviews a continuous integrated computer based approach to monitoring oxygen supply (DO 2) and consumption (VO 2) relationships. A description of the technologic methodology and potential advantages over intermittent thermodilution monitoring are discussed. Lastly, the preliminary results of investigations in two populations (abdominal aortic surgery and adult respiratory distress syndrome) are presented. Read More

    Oxygen delivery and utilization.
    Appl Cardiopulm Pathophysiol 1991 ;3(4):345-50
    Department of Medicine, Long Island Jewish Medical Center, New Hyde Park, NY 11042.
    Under normal circumstances, O 2 transport (TO 2 = cardiac output x arterial O 2 content) is regulated to provide sufficient O 2 to meet the demands of oxidative phosphorylation, quantified as the O 2 consumption (VO 2). When metabolic demands increase, TO 2 is augmented and in addition, the fractional extraction of the delivered O 2 by the tissues, the O 2ER, also increases, to levels as high as 0.80 at maximum VO 2.

    Shock: new developments in the management of shock.
    Appl Cardiopulm Pathophysiol 1991 ;4(2):103-7
    Department of Medicine, University of Health Sciences/The Chicago Medical School, Illinois.
    Circulatory shock represents critical reductions of blood flow to tissues with curtailed delivery of energy substrate and especially oxygen. Generation of lactic acid highlights the onset of anaerobic metabolism and represents the clinical hallmark of perfusion failure. For the purpose of classification, prognostication and management, we now recognize four mechanisms by which circulatory shock may evolve. Read More

    Recent advances in cardiopulmonary resuscitation.
    Appl Cardiopulm Pathophysiol 1991 ;4(2):97-102
    Department of Medicine, University of Health Sciences/The Chicago Medical School, Illinois.
    Reversal of cardiac arrest is contingent on rapid and effective restoration of myocardial blood flow. Thirty years have elapsed since closed-chest cardiopulmonary resuscitation (CPR) was introduced in clinical practice. Because of its technical simplicity and noninvasiveness, CPR was rapidly implemented and almost universally utilized for cardiac resuscitation. Read More

    Use of PEEP in management of life-threatening status asthmaticus: a method for the recovery of appropriate ventilation-perfusion ratio.
    Appl Cardiopulm Pathophysiol 1991 ;4(1):79-83
    Department of Medical Intensive Care Unit and Department of Physiology, University of Liège, Belgium.
    In 15 patients with asthma attack, evidence of the uneven distribution of air flow during controlled ventilation was obtained by detection of ventilatory asynchronism expressed by the incurvated profile of tracheal pressure waves associated with the repetitive interruptions of air flow. It was observed that low values of PEEP (mean: 5 +/- 2.5 cm H 2O) induced an increase in transbronchial pressure able to overcome ventilatory asynchronism. Read More

    Nuclear medicine in ARDS: clinical applications.
    Appl Cardiopulm Pathophysiol 1991 ;4(1):55-62
    C.N.R. Instituto di Fisiologia Clinica, Universitá di Pisa, Italy.
    ARDS is still characterized by an exceedingly high mortality rate. Methods are then needed to detect ARDS at the earliest clinical stage. Over the last decade, radioisotopic techniques have developed, aimed at demonstrating an abnormal neutrophil sequestration in the lung or detecting functional alterations of the pulmonary alveolar-capillary barrier, which likely precede the onset of respiratory distress.

    Surgical and catheter ablative techniques for treating supraventricular tachycardia.
    Appl Cardiopulm Pathophysiol 1991 ;4(1):27-32
    Electrophysiology Laboratory, Division of Cardiology, University of Texas Medical School at Houston.
    Although antiarrhythmic drugs are commonly used in patients with supraventricular tachycardia, their use is limited due to inefficacy, side effects and patient compliance problems. Nonpharmacologic therapies used in the treatment of supraventricular tachycardia include: antitachycardia pacing, DC and radiofrequency catheter ablation and surgical therapy. Although certain pacing techniques can prevent the initiation of tachycardia, antitachycardia pacing is primarily used to terminate the supraventricular tachycardia once it has occurred. Read More

    A critical appraisal of the cardiac arrhythmia suppression trial (CAST).
    Appl Cardiopulm Pathophysiol 1991 ;4(1):9-16
    The Electrophysiology Laboratory, Division of Cardiology, University of Texas Medical School at Houston.
    The presence of ventricular ectopic activity in the post-myocardial infarction patient, especially associated with left ventricular dysfunction, has been associated with a high incidence of sudden cardiac death. To test the PVC hypothesis, that PVC suppression in asymptomatic patients with ventricular arrhythmias post-myocardial infarction might reduce sudden death rate, the cardiac arrhythmia suppression trial (CAST) was performed. In patients treated with encainide or flecainide, total mortality at 10 months was 7. Read More
