Brachycephalic airway syndrome (BAS) is characterized by increased upper airway resistance due to conformational abnormalities occurring in brachycephalic dogs (BD). In this prospective study, we evaluated pulse oximetry (SpO2 ) and arterial blood gas values in 18 healthy BD and compared these values with those of 18 healthy mesocephalic and dolichocephalic dogs (MDD). All dogs were assigned a BAS score based on an owner questionnaire. Inclusion criteria included presentation to the hospital for a problem unrelated to the respiratory system and unremarkable blood analyses and physical examination...

As the mechanism of aged black garlic (ABG) extract affecting lipid metabolism in adipocytes remains unclear, this study evaluated the effect of ABG extract on lipid metabolism and the expression of related proteins in mature 3T3-L1 adipocytes. ABG extract treatments at 0, 0.625, 1.25, and 2.5, and 5 mg/mL had no effect on cell morphology or viability in adipocytes. ABG extract suppressed lipogenesis and induced lipolysis in a dose-dependent manner compared to control. Furthermore, ABG extract at 2.5 and 5 mg/mL significantly reduced protein expression of proliferator activated receptor γ (PPARγ) and perilipin in mature 3T3-L1 adipocytes...

Neck haematoma following thyroid surgery can present with respiratory distress which is generally attributed to airway obstruction. We recently had a 63-year-old female patient who underwent total thyroidectomy for toxic nodular goitre. However, within 4 hours of surgery, she developed sudden respiratory distress which was managed by prompt evacuation of the neck haematoma. Just before the haematoma evacuation, the patient had hypertension and bradycardia along with the distress. The arterial blood gas analysis sampled at that time was normal...

Traditional validation of umbilical cord blood samples with positive veno-arterial (V-A) ΔpH and A-V ΔpCO2 values confirms the source of samples, where negative Δvalues represent mix-up of samples. To investigate whether this is true, the distributions of V-A ΔpO2 and A-V Δlactate were also explored and related to clinical characteristics. In addition, different cord blood sampling techniques were evaluated MATERIAL AND METHODS: Register study with cord blood acid-base and clinical data from 27 233 newborns...

BACKGROUND: The open lung approach (OLA) reportedly has lung-protective effects against acute respiratory distress syndrome (ARDS). Recently, lowering of the driving pressure (ΔP), rather than improvement in lung aeration per se, has come to be considered as the primary lung-protective mechanism of OLA. However, the driving pressure-independent protective effects of OLA have never been evaluated in experimental studies. We here evaluated whether OLA shows protective effects against experimental ARDS even when the ΔP is not lowered...

BACKGROUND: Theoretical disadvantages are associated with the use of heat-crimped piston prostheses in stapedotomy. Loose crimping could result in prosthesis displacement or slippage. Alternatively, overly tight crimping may cause trauma to the incus with resultant necrosis. OBJECTIVES: 1) Analyze outcomes of patients undergoing stapedotomy with heat-activated piston-style prostheses, and 2) compare outcomes between prostheses made by different manufacturers. STUDY DESIGN: Retrospective...

BACKGROUND AND PURPOSE: Experienced freedivers can endure prolonged breath-holds despite severe hypoxemia and are therefore ideal subjects to study apnea-induced cerebrovascular reactivity. This multiparametric study investigated CBF, the spatial coefficient of variation as a correlate of arterial transit time and brain metabolism, dynamics during prolonged apnea. MATERIALS AND METHODS: Fifteen male freedivers (age range, 20-64 years; cumulative previous prolonged breath-holds >2 minutes and 30 seconds: 4-79,200) underwent repetitive 3T pseudocontinuous arterial spin-labeling and 31 P-/1 H-MR spectroscopy before, during, and after a 5-minute breath-hold (split into early and late phases) and gave temporally matching venous blood gas samples...

Arterial blood gas (ABG) analysis is the traditional method for measuring the partial pressure of carbon dioxide. In mechanically ventilated patients a continuous noninvasive monitoring of carbon dioxide would obviously be attractive. In the current study, we present a novel formula for noninvasive estimation of arterial carbon dioxide. Eighty-one datasets were collected from 19 anesthetized and mechanically ventilated pigs. Eleven animals were mechanically ventilated without interventions. In the remaining eight pigs the partial pressure of carbon dioxide was manipulated...

Background: CO2 insufflation could provide a better surgical field during single-incision thoracoscopic surgery (SITS) with small tidal two-lung ventilation (ST-TLV). Here we compared the surgical field and physiological effects of ST-TLV with and without CO2 during SITS. Methods: Patients underwent scheduled SITS bullectomy. Surgery under ST-TLV general anesthesia performed without CO2 (group NC) or with CO2 insufflation (group C). The surgical field was graded at thoracoscope introduction and at bulla resection as follows: good (more than half of the 1st rib visible; bleb easily grasped with the stapler), fair (less than half of the 1st rib visible; some manipulation needed to grasp the bleb with the stapler), or poor (1st rib non-visible; bleb ungraspable)...

BACKGROUND AND OBJECTIVE: Chronic respiratory failure (CRF) with hypoxaemia is an important pathophysiology in patients with chronic obstructive pulmonary disease (COPD), and existing mild hypoxaemia may be a sign of future CRF development. However, little is known about the trajectory of partial arterial pressure of oxygen (PaO2 ) decline in patients with COPD. We assessed decline in PaO2 and the impact of short-term reductions in PaO2 to predict future decline in PaO2 . METHODS: A total of 172 outpatients with COPD from a prospective cohort study were enrolled...
