An abrupt increase in end-tidal CO2 (EtCO2; from 35 to 58 mm Hg) followed by a sudden fall (to 18 mm Hg) was noted during retroperitoneoscopic adrenalectomy under general anaesthesia in a 23-year-old patient with adrenal hyperplasia. This was accompanied by hypotension (systolic blood pressure of 60 mm Hg), desaturation (88% SpO2) and ST depression (3.5 mm). The patient was resuscitated with fluids and vasopressor drugs and about 4 mL of air was aspirated through the central venous catheter, confirming the diagnosis of an intraoperative gas embolism...

BACKGROUND: Sitting position is preferred during posterior fossa surgeries as it provides better anatomical orientation and a clear surgical field. However, its use has been declining due to its propensity to cause life-threatening complications. This study was carried out to analyze the perioperative complications and postoperative course of children who underwent neurosurgery in sitting position. MATERIALS AND METHODS: Medical records of 97 children (<18 years) who underwent neurosurgery in sitting position over a period of 12 years, were retrospectively analyzed...

Primary medullary hemorrhage is a rare event that may result in ataxic respiration. Although it remains controversial whether primary medullary hemorrhage should be managed conservatively or surgically, recent advancements in neuroimaging and microsurgical techniques have shown promise for improving outcomes and prognosis following surgery. The present report discusses the case of a 70-year-old woman admitted to our institution due to sudden-onset nausea and vomiting. The patient underwent surgical removal of a right medullary hematoma for the treatment of daytime respiratory depression and nocturnal apnea while in the half-sitting position...

Cerebral air embolism is a rare clinical entity in day-to-day practice. The introduction of air into the venous or the arterial system can cause cerebral air embolism leading to severe neurological deficits. The common causes reported in the literature are iatrogenic; it can be caused by positive pressure maneuvers performed during cardiac resuscitation, lung biopsy, and the placement of venous catheters in the presence of a patent foramen ovale. We report a case of cerebral air embolism which has occurred secondary to lung laceration...

Cerebral air embolism is caused by gas bubbles in the vascular system. These bubbles can cause cerebral ischemia by obstructing encephalic blood vessels. It is frequently associated with blunt and penetrating chest trauma as well as iatrogenic interventions. Lung trauma involving laceration of the respiratory tract, lung parenchyma, and blood vessels may result in direct communication of these structures, driving air or gas into the pulmonary venous system. We report a case of a blunt chest trauma that led to massive arterial air embolism that was possible to recognize with the help of postmortem computed tomographic scan examination...

BACKGROUND: Thromboelastography (TEG) in venous air embolism (VAE) has been poorly studied. We induced coagulation abnormalities by VAE in a rat model, assessed by TEG with and without mexiletine, a lidocaine analogue local anesthetic. METHODS: Twenty-three Sprague Dawley rats instrumented under isoflurane anesthesia and allowed to recover five days prior to the experiments were randomized into three experimental groups: 1) VAE (n = 6); 2) VAE and mexiletine (n = 9); and 3) normal saline (NS) alone (control group, n = 8)...

Venous air embolism is a dreaded condition particularly relevant to the field of nephrology. In the face of a favourable, air-to-blood pressure gradient and an abnormal communication between the atmosphere and the veins, air entrance into the circulation is common and can bring about venous air embolism. These air emboli can migrate to different areas through three major routes: pulmonary circulation, paradoxical embolism and retrograde ascension to the cerebral venous system. The frequent undesirable outcome of this disease entity, despite timely and aggressive treatment, signifies the importance of understanding the underlying pathophysiological mechanism and of the implementation of various preventive measures...

OBJECTIVES: Oxygenator failure during cardiopulmonary bypass constitutes a life-threatening event, especially when perfusion is conducted under normothermia. An alternative solution to emergency oxygenator changeover is described. METHODS: A supplementary oxygenator is added in the venous line without interrupting perfusion. De-airing is achieved through the cardiotomy reservoir. Oxygen supply is adapted to ensure physiologic partial oxygen pressure. RESULTS: On 5 occasions in the past 4 years, Capiox Baby FX 05 oxygenator (n = 4) and Capiox FX15 (n = 1) failed to exchange blood gases after bypass run ranging from 290 min to 563 min...

Intravenous catheterization is a necessity for continuous administration of intravenous fluids and for intermittent intravenous access to avoid discomfort and potential complications of repeated needle insertions into the vein. Intravenous catheterization is commonly performed and well tolerated in horses, but catheter associated complications have been reported. The most commonly reported complication is thrombophlebitis, but others such as venous air embolism, exsanguination and catheter fragmentation may also occur...

Cerebral air embolism (CAE) is a potentially fatal iatrogenic complication related to common procedures including central venous catheter (CVC) removal. We report an interesting case of CAE related to CVC removal that was further complicated with status epilepticus. Neuroimaging of CAE and status epilepticus could pose diagnostic dilemmas and require consideration of wide diagnostic differentials. We discuss the clinical presentation, mechanism, and diagnostic approach, especially neuroimaging to differentiate various etiologies in CAE patients...

Etiologic diagnosis of an eosinophilic pleural effusion (EPE) presents a diagnostic challenge when intrapleural air and blood have been ruled out as its proximate causes. Among the causes of EPE, those that require immunosuppression for the underlying disease include connective tissue diseases, sarcoidosis, vasculitis, and eosinophilic pneumonia. We present a case of clinically suspected Behcet's syndrome based on a 10-year history of recurrent multiple oral ulcers and human leukocyte antigen-B51 positivity who presented with only an EPE...

In recent years, several studies have consistently described the chronobiologic aspects of many cardiovascular diseases. Several studies have also assessed the circadian and circannual patterns of occurrence and mortality of deep vein thrombosis and pulmonary embolism, but the results have been less univocal. Different mechanisms have been proposed to explain these possible patterns, including oscillation of coagulation proteins, the role of meteorologic parameters, and air pollution. This article summarizes the available evidence on chronobiologic aspects of venous thromboembolism and discusses the casual mechanism...

Cerebral gas embolism (CGE) from the thoracic cavity is commonly associated with invasive procedures, and cases of spontaneous CGE are rare. A 78-year-old man presented with severe spontaneous CGE associated with combined pulmonary fibrosis and emphysema (CPFE). To the best of our knowledge, the comorbidity of CGE in a CPFE patient has not been documented until now. The patient became unconscious with left hemiparesis at approximately 2 a.m. Computed tomography scan revealed minute air densities scattered in the deep white matter of the right frontal lobe...
