Extracorporeal membrane oxygenation system is used for rescue treatment strategies for temporary cardiopulmonary function support to facilitate adequately oxygenated blood to return into the systemic and pulmonary circulation systems. Therefore, a servo flow regulator is used to adjust the roller motor speed, while support blood flow can match the sweep gas flow (GF) in a membrane oxygenator. A generalised regression neural network is designed as an estimator to automatically estimate the desired roller pump speed and control parameters...

Case: "Cannot intubate, cannot oxygenate" (CICO) is a rare, life-threatening situation. We describe a pediatric case of CICO and highlight some educational points.A 3-year-old boy who collapsed in the bathtub came to our emergency department. On admission, he went into cardiac arrest probably because of an airway obstruction. We judged his condition as CICO and carried out an emergent tracheostomy after several attempts to perform a cricothyroidotomy failed. We continued resuscitation; however, circulation did not return spontaneously...

BACKGROUND: Ventilation through small-diameter tubes typically precludes use of a cuff as this will impede the necessary passive outflow of gas alongside the tube's outer surface. Ventrain assists expiration and enables oxygenation and normoventilation through small-bore cannulas or catheters, particularly in obstructed airways. A small-bore ventilation catheter (SBVC; 40 cm long, 2.2 mm inner diameter) with a separate pressure monitoring lumen and a cuff was developed. Efficacy of oxygenation and ventilation with Ventrain through this catheter was investigated in sealed and open airways in a porcine cross-over study...

BACKGROUND: Nosocomial infections occurring during extracorporeal membrane oxygenation (ECMO) support have already been reported, but few studied infections directly related to ECMO devices. This study aims to evaluate the rate of both colonisations and infections related to ECMO devices at the time of ECMO removal. RESULTS: We included all consecutive adult patients treated with venovenous ECMO (VV-ECMO) for at least 48 h during a 34-month study. At the time of ECMO removal, blood cultures, swab cultures on insertion cannula site and intravascular cannula extremity cultures were systematically performed...

Lactic acid and base deficit (BD) values are frequently monitored in the intensive care unit and operating room setting to evaluate oxygenation, ventilation, cardiac output, and peripheral perfusion. Although generally obtained from an arterial cannula, such access may not always be available. The current study prospectively investigates the correlation of arterial and peripheral venous values of BD and lactic acid. The study cohort included 48 patients. Arterial BD values ranged from -8 to 4 mEq/L and peripheral venous BD values ranged from -8 to 4 mEq/L...

Two experiments were conducted to investigate the effect of combined supplementation of α-galactosidase and xylanase on nutrient digestibility and growth performance in growing pigs. Experiment 1 had a 2 × 2 Latin square design, where eight barrows (45.0 ± 0.52 kg body weight [BW]) were fitted with a simple T-cannula in the distal ileum and received a basal diet without or with supplementation of α-galactosidase (12 U/kg diet) and xylanase (15 AXC/kg diet) within two periods of 10 d. The apparent ileal digestibility (AID) and apparent total tract digestibility of nutrients, pH, viscosity of digesta and digestive enzyme activities were assessed...

The present study was conducted to investigate the postileal P digestion response of growing pigs to dietary P concentrations and sources. Twenty-four pigs (57.3 ± 1.9 kg initial BW) fitted with T-cannulas at the distal ileum were assigned to a duplicated 12 × 4 incomplete Latin square design with 12 diets and 4 periods. The 12 experimental diets consisted of 9 cornstarch-based diets using soybean meal (SBM), corn distiller's dried grains with solubles (DDGS), and canola meal (CM) as assay ingredients at 3 levels and 3 corn-SBM-based practical diets with 3 levels of dicalcium phosphate (DCP)...

OBJECTIVES: In patients with acute hypoxemic respiratory failure, noninvasive ventilation and high-flow nasal cannula oxygen are alternative strategies to conventional oxygen therapy. Endotracheal intubation is frequently needed in these patients with a risk of delay, and early predictors of failure may help clinicians to decide early. We aimed to identify factors associated with intubation in patients with acute hypoxemic respiratory failure treated with different noninvasive oxygenation techniques...

#18
Autumn Riddell
Apneic oxygenation during intubation is the application of oxygen via a nasal cannula, which is left in place throughout laryngoscopy. The flow rate of oxygen is set to at least 15 L/min and theoretically reduces the risk of oxygen desaturation and hypoxemia during the procedure. Over the last 5 years, there have been several studies published on this topic with differing results. Despite conflicting results, use of apneic oxygenation is becoming more prevalent and is being implemented into standard operating procedures in some clinical settings...

Sustained local delivery of drugs to the inner ear may be required for future regenerative and protective strategies. The round window is surgically accessible and a promising delivery route. To be viable, a delivery system should not cause hearing loss. This study determined the effect on hearing of placing a drug-delivery microcatheter on to the round window, and delivering either artificial perilymph (AP) or brain-derived neurotrophic factor (BDNF) via this catheter with a mini-osmotic pump. Auditory brainstem responses (ABRs) were monitored for 4 months after surgery, while the AP or BDNF was administered for the first month...
