OBJECTIVE Blood loss in hepatic resection is an important determinant of operative outcome. OBJECTIVE To clarify whether reducing the tidal volume would be effective in decreasing blood loss during liver transection. METHODS Randomized controlled trial. METHODS University hospital. METHODS Eighty

A 60-year-old male developed chronic respiratory failure due to central hypoventilation after cerebellar bleeding. We implanted a diaphragm pacemaker (radio-frequency type) to the patient, and his respiratory status was improved. Although this apparatus devised by Glenn has been widely used in the

"Permissive hypoventilation" in a swine model of hemorrhagic shock.

BACKGROUND Many penetrating trauma patients in severe hemorrhagic shock receive positive pressure ventilation (PPV) upon transport to definitive care, either by intubation (INT) or bag-valve mask (BVM). Using a swine hemorrhagic shock model that simulates penetrating trauma, we proposed that

Cerebral oxygenation during hemorrhagic shock: perils of hyperventilation and the therapeutic potential of hypoventilation.

OBJECTIVE Prophylactic hyperventilation of patients with head injuries worsens outcome, presumably by exacerbating tissue hypoxia. Oxygen tension in brain tissue (PbrO2) provides a direct measurement of cerebral metabolic substrate delivery and varies with changing end-tidal carbon dioxide tension

[Central alveolar hypoventilation as a complication of massive intracerebellar hemorrhage: report of a case treated by diaphragm pacing].

The author reported a case of central alveolar hypoventilation (Ondine's curse) which was treated by diaphragm pacing. A 59-year-old man was admitted because of sudden deep coma and tetraparesis. Neurological examination on admission showed miotic pupils with absent light reaction, no oculocephalic

Effect of hemorrhagic hypotension and hypoventilation on lower esophageal sphincter pressure.

Dysfunction of the lower esophageal sphincter has been demonstrated in the cat shock model. Analogies have been drawn to reflux and aspiration in the critically ill patient. In a cat shock model, lower esophageal sphincter pressure is reduced and response to bethanechol is impaired. Upon

OBJECTIVE This study was undertaken to discover if impaired blood clearance functions and killing capacity of the reticuloendothelial system contribute to the high occurrence rate of septic complications after shock, trauma, and thermal injury. METHODS Prospective, randomized, controlled

In this article, we describe a case of a subarachnoid hemorrhage (SAH) in an acute severe asthma patient following mechanical hypoventilation. A 49-year-old man was admitted to an Intensive Care Unit with an acute exacerbation of asthma. After 3 days of mechanical ventilation (hypercapnia and

A quantitative study of some factors affecting the outcome of experimental epidural bleeding in swine.

During an experimentally induced aggressive epidural bleed the effect on outcome of haematoma volume, cerebral perfusion pressures, intracranial pressure gradients and ventilation were examined in a swine model. Two groups of experiments were performed using either spontaneous ventilation (group 1,

Cardiopulmonary interventions to decrease blood loss and blood transfusion requirements for liver resection.

BACKGROUND Blood loss during liver resection is one of the most important factors affecting the peri-operative outcomes of patients undergoing liver resection. OBJECTIVE To determine the benefits and harms of cardiopulmonary interventions to decrease blood loss and to decrease allogeneic blood

Effect of intraventricular hemorrhage on pulmonary function in newborn piglets.

Intracranial hemorrhage in the premature infant is often associated with respiratory failure and need for mechanical ventilation. We therefore addressed the question of possible interactions with and pulmonary consequences of intraventricular hemorrhage. Newborn piglets were studied during

A 29-year-old woman, addicted to heroin since the age of 15 years, presented with a 4-day history of acute inspiratory chest pain, dyspnoea and vomiting associated with hypoventilation. She died 3 h after admission to the intensive care unit in spite of active resuscitative measures. The main

An 18-month-old male Belgian horse was anesthetized and placed in dorsal recumbency for cryptorchidectomy. Xylazine was used for sedation and guaifenesin with thiamylal for induction of anesthesia. A surgical plane of anesthesia was maintained with halothane. During anesthesia, second-degree

Central Hypoventilation Syndrome Complicated with Lateral Medullary Infarction after Endovascular Treatment of the Vertebral Artery Dissecting Aneurysm: A Case Report.

Lateral medullary infarction rarely leads to central hypoventilation syndrome (CHS). CHS is a life-threatening disorder characterized by hypoventilation during sleep. We report the first case of CHS as a complication of lateral medullary infarction after endovascular treatment. A 65-year-old man

Effect of venous hypercarbia and hyperventilation on myocardial contractility in canine haemorrhagic shock.

To study the effect of venous hypercarbia on myocardial contractility, haemorrhagic shock was produced in six healthy mongrel dogs by ex-sanguination of 15 ml of blood/kg body weight every 20 minutes till a loss of 45 ml/kg was achieved. After recording haemodynamic and respiratory parameters, the
