Effects of inhaled nitric oxide on oxygenation and haemodynamic performance during one-lung ventilation in pigs
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: K Schwarzkopf --- Department of Anaesthesiology and Intensive Care Medicine, Germany T Schreiber --- Institute for Experimental Animals, University of Jena, Germany H Schubert --- Institute for Experimental Animals, University of Jena, Germany N Preussler --- Department of Anaesthesiology and Intensive Care Medicine, Germany L Hueter --- Department of Anaesthesiology and Intensive Care Medicine, GermanyObjective: To study the effects of 20 ppm inhaled nitric oxide (iNO) on haemodynamics and systemic oxygenation during one-lung ventilation (OLV) in vivo. Design: Prospective animal study with a cross-over design. Setting: Animal laboratory of a university hospital. Subjects: Eight... -
Anaesthesia and subglottic airway obstruction
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: BA Bulbulia --- Garden City Clinic, South Africa R Ahmed --- Chris Hani Baragwanath Hospital, South AfricaIn this article, we describe the anaesthetic management and laser excision of a subglottic tumour that caused upper airway obstruction. Stridor was the presenting feature. A good history and careful assessment will reduce the likelihood of erroneous or delayed diagnosis... -
Difficult airways: a reliable “Plan B”
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: DG Bishop --- Pietermaritzburg Metropolitan Department of Anaesthesia, Critical Care and Pain Management, Z Farina --- Pietermaritzburg Metropolitan Department of Anaesthesia, Critical Care and Pain Management, RD Wise --- Pietermaritzburg Metropolitan Department of Anaesthesia, Critical Care and Pain Management,Percutaneous transtracheal jet ventilation (PTJV) is an accepted method of rescue ventilation following unsuccessful attempts to secure the airway through conventional methods. Pre-emptive use of PTJV in the difficult airway has also been described as using either a specifically designed... -
The Laryngeal Mask Airway Supreme™: safety and efficacy during gynaecological laparoscopic surgery
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: JM Beleña --- Department of Anaesthesiology and Critical Care, Spain M Núñez --- Department of Anaesthesiology and Critical Care, Spain JL Gracia --- Department of Anaesthesiology and Critical Care, Spain JL Pérez --- Department of Anaesthesiology and Critical Care, Spain J Yuste --- Department of Anaesthesiology and Critical Care, SpainBackground: Laryngeal Mask Airway Supreme™ (LMA Supreme™) is a new single-use polyvinyl chloride supraglottic device that offers gastric access. To date, studies that have tested the LMA Supreme™) for use in laparoscopic surgery have been reported. We present the largest... -
Another method to maintain positive-pressure ventilation through the Montgomery® T tube
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: R Saroa --- Department of Anaesthesia and Critical Care, S Singhal --- Department of ENT, S Palta --- Department of Anaesthesia and Critical Care, IndiaWe describe airway management in a patient who had a Montgomery® T tube in situ. The main concern pertaining to these patients is the inadequate depth of anaesthesia and ventilation, in view of loss of volume of air and gases,... -
Are lung-protective ventilation strategies worth the effort?
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: P Slinger --- University of Toronto,Nonphysiological ventilation in healthy lungs induces acute lung injury (ALI). Protective lung ventilation in patients with ALI improves outcome. Protective lung ventilation in noninjured lungs and in the absence of a primary pulmonary insult may initiate ventilation-induced lung injury (VILI),... -
Intubation and mechanical ventilation: knowledge of medical officers at a South African secondary hospital
Item type: Journal Article • Journal: South African Family Practice • Authors: Linda van Deventer --- Department of Critical Care, South AfricaBackground: Medical officers frequently need to initiate the management of critically ill patients requiring endotracheal intubation and mechanical ventilation. The knowledge of hospital-based medical officers at a South African secondary hospital was evaluated on indications for endotracheal intubation and the... -
Hypoxia tolerance of introduced Nile perch: implications for survival of indigenous fishes in the Lake Victoria basin
Item type: Journal Article • Journal: African Zoology • Authors: Pamela J. Schofield --- Department of Zoology, U.S.A. Lauren J. Chapman --- Department of Zoology, U.S.A.The introduction of predatory Nile perch (Lates niloticus) into the Lake Victoria basin coincided with a dramatic decline in fish diversity. However, remnant populations of indigenous fishes persist in lagoons and satellite lakes separated from the main lakes by extensive... -
Perioperative ARDS and lung injury: for anaesthesia and beyond
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: Robert Wise --- Perioperative Research Unit, Metropolitan Department of Anaesthetics, Critical Care and Pain Management, Pietermaritzburg, South Africa David Bishop --- Perioperative Research Unit, Metropolitan Department of Anaesthetics, Critical Care and Pain Management, Pietermaritzburg, South Africa Gavin Joynt --- Department of Anaesthesia and Intensive Care, Hong Kong Reitze Rodseth --- Perioperative Research Unit, Metropolitan Department of Anaesthetics, Critical Care and Pain Management, Pietermaritzburg, South AfricaPostoperative pulmonary complications are common and may be associated with significant cost. Acute respiratory distress syndrome (ARDS), a life-threatening respiratory disease process characterised by hypoxaemia and reduced lung compliance, is one of the more serious pulmonary complications. The development of... -
The effect of different anaesthetic mask shapes on the anatomical dead space using infant, child and adult part-task trainers
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: L Botes --- School of Medicine, South Africa J Jacobs --- School of Medicine, South Africa R Rademeyer --- School of Medicine, South Africa S Van der Merwe --- School of Medicine, South Africa L Van Heerden --- School of Medicine, South Africa BJS Diedericks --- Department of Anaesthesiology, South AfricaDead space is the portion of tidal volume that does not participate in alveolar gas exchange. The purpose of this study was to compare the dead space contribution of differently shaped masks, of the same size, by measuring the volume... -
Cold storage for low-cost air-conditioning
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Daniel M. Madyira --- Department of Mechanical Engineering Science, South AfricaBuilding heating, ventilation and air-conditioning (HVAC) consumes 50% of the building energy consumption. Such high costs are based on the conventional HVAC cycles for air cooling based on grid connected buildings. However, there are alternative passive and active cold storage... -
