OBJECTIVES: The common femoral artery is the standard site for immediate vascular access when initiating adult venoarterial extracorporeal membrane oxygenation. However, this approach is fraught with problems such as femoral artery occlusion, distal limb ischemia, reperfusion injury resulting in compartment syndrome, retroperitoneal hemorrhage, thrombosis, embolization, and most importantly, pulmonary edema. Here, we show our preference of using the subclavian artery with a side graft as a different cannulation technique for outflow of extracorporeal membrane oxygenation, which can avoid complications associated with different access techniques...

We collected venous blood samples from 83 apparently healthy Mottled Ducks ( Anas fulvigula ) July 2012-August 2013 on the Texas, USA, Gulf Coast and measured blood gas, electrolyte, biochemical, and hematologic parameters. Age, sex, body condition score, capture year, capture type, and time of day had significant statistical, but not clinically relevant, effects on several analytes. Ducks caught by rocket net had findings consistent with greater stress compared with hand-caught ducks. These analyte data for healthy free-living Mottled Ducks may be useful in the assessment of Mottled Duck population health and in the management and treatment of individual ducks affected by environmental stressors...

Diagnosis and treatment monitoring of cerebrovascular diseases routinely require hemodynamic imaging of the brain. Current methods either only provide part of the desired information or require the injection of multiple exogenous agents. In this study, we developed a multiparametric imaging scheme for the imaging of brain hemodynamics and function using gas-inhalation MRI. The proposed technique uses a single MRI scan to provide simultaneous measurements of baseline venous cerebral blood volume (vCBV), cerebrovascular reactivity (CVR), bolus arrival time (BAT), and resting-state functional connectivity (fcMRI)...

In neonatology, blood gas analysis is a useful tool in the evaluation of the health of newborns and plays a key role in early detection of critically ill subjects. Because blood gas analysis parameters have not previously been studied in any depth in donkey foals, this study was performed on 16 healthy Martina Franca donkey foals born after an uncomplicated delivery. Arterial and venous blood samples were collected at 5 minutes and at 12, 24, 72, and 96 hours of age. Blood gas analysis was performed by a portable analyzer, measuring arterial and venous total carbon dioxide, carbon dioxide partial pressure (pCO2), oxygen partial pressure (pO2), oxygen saturation (sO2), bicarbonate, base excess (BE), pH, and lactate (LT)...

Cerebral air embolism (CAE) is an infrequently reported complication of routine medical procedures. We present two cases of CAE. The first patient was a 55-year-old male presenting with vomiting and loss of consciousness one day after his hemodialysis session. Physical exam was significant for hypotension and hypoxia with no focal neurologic deficits. Computed tomography (CT) scan of head showed gas in cerebral venous circulation. The patient did not undergo any procedures prior to presentation, and his last hemodialysis session was uneventful...

A 40-year-old woman withuntreated type II diabetes mellitus was discovered withcardiopulmonary arrest in her room. On admission, she had ventricular fibrillation. After cardiopulmonary resuscitation, her own pulse restarted. The plasma glucose was 722 mg/dl and venous PH was 6.704. Abdominal computed tomography revealed gas within the parenchyma of the left kidney. We diagnosed her with emphysematous pyelonephritis and conducted emergency nephrectomy. Urinary and blood cultures were positive for Escherichia coli...

Monitoring veno-venous extracorporeal membrane oxygenation (vvECMO) during 76 days of continuous support in a 42-years old patient with end-stage pulmonary disease, listed for double-lung transplantation. Applying a new monitor (Landing(®), Eurosets, Medolla, Italy) and describing how measured and calculated parameters can be used to understand the variable interdependency between artificial membrane lung (ML) and patient native lung (NL). During vvECMO, in order to understand how the respiratory function is shared between ML and NL, ideally we should obtain data about oxygen transfer and CO2 removal, both by ML and NL...

BACKGROUND: Xenon (Xe) in many respects is an ideal anaesthetic agent. Its blood/gas partition coefficient is lower than that of any other anaesthetic, enabling rapid induction of and emergence from anaesthesia. While the whole body kinetics during wash-in of inhalational anaesthesia is well known, data describing the pharmacokinetics of xenon in the cerebral compartment at the site of action are still largely missing. METHODS: In order to illuminate xenon´s cerebral pharmacokinetics, we anaesthetised five pigs and measured arterial, mixed- and sagittal sinus-venous blood, as well as end-expiratory gas concentrations of xenon by gas chromatography-mass spectrometry (GCMS) up to 30 minutes after starting the anaesthetic gas mixture...

Patients on chronic hemodialysis have a shortened survival compared to the general population. There are multiple sources of morbidity and mortality unique to the dialysis population that account for this. Reasons include the effects of blood membrane interactions, intradialytic hypotension, myocardial stunning, excessive interdialytic weight gain, high-flow arteriovenous fistulae, and impaired lipid break down by anticoagulation administered during HD. Another risk factor, not well appreciated, is the occurrence of microemboli of air (microbubbles) during HD...

BACKGROUND: Umbilical cord blood gas values are better indicators of perinatal asphyxia than Apgar scores. Many studies have reported normal ranges of umbilical cord blood gases, which vary greatly due to many factors. This study aimed to establish the reference values of umbilical cord blood gases of normal cesarean newborns in a university hospital setting. MATERIAL AND METHOD: Blood samples from the umbilical artery and vein were collected from 160 newborns delivered by elective cesarean section...
