It is well documented that pressure-controlled ventilation (PCV) improves oxygenation and ventilation compared to volume-controlled ventilation and reduces peak airway pressure in gynecological laparoscopy. PCV with moderately inversed inspiratory-expiratory (I: E) ratio can successfully recruit collapsed alveoli and has been proved to be beneficial in intensive care. We tested the ...

AIMS: (±)-Tramadol hydrochloride (tramadol) is a widely used analgesic that stimulates the µ-opioid receptor and inhibits the reuptake of serotonin and noradrenalin. Although tramadol is also known to inhibit the micturition reflex in rats, its effects on urethral continence function have not been reported. We therefore examined whether intravenous tramadol ...

Aims: Oxidative stress has been recently postulated to be an important factor in the pathogenesis and development of arteriosclerosis. Although urinary 8-hydroxydeoxyguanosine (8-OHdG) is clinically used as a marker of oxidative stress, its usefulness in diagnosing arteriosclerosis has not been fully examined. This study aimed to evaluate the association between ...

Vesicouterine fistula after obstructed labor is very rare. Hysterosalpingography is the investigation of choice. Cystography primarily does not demonstrate the fistula because the intrauterine pressures are higher than the vesical pressure. A 38-year-old woman presented to us with vecisovaginal fistula and vesicouterine fistula that had developed 13 years earlier after ...

I.V. fluid therapy does not result in the extracellular volume distribution expected from Starling's original model of semi-permeable capillaries subject to hydrostatic and oncotic pressure gradients within the extracellular fluid. Fluid therapy to support the circulation relies on applying a physiological paradigm that better explains clinical and research observations. The ...

In a healthy human, deep inspirations produce bronchodilation of contracted airways, which probably occurs due to the transient distension of the airway smooth muscle (ASM). We hypothesised that deep expiratory manoeuvres also produce bronchodilation due to transient airway wall and ASM compression. We used porcine bronchial segments to assess the ...

We report two cases of normal perfusion pressure breakthrough phenomenon after total brain arteriovenous malformation removal. Hereby, we demonstrate that not only autoregulation impairment in the ipsilateral hemisphere occurs but also contralateral remote vessels response does. Such findings may be observed at 2-4 weeks and may resolve after 1-3 months.

RATIONALE: In spite of its ability to reduce overall ventilation time, protocol-guided weaning from mechanical ventilation is not routinely used in daily clinical practice. Clinical implementation of weaning protocols could be facilitated by integration of knowledge-based, closed loop-controlled protocols into respirators. OBJECTIVE: To determine whether automated weaning decreases overall ventilation ...

Manual blood pressure (BP) is gradually disappearing from clinical practice with the mercury sphygmomanometer now considered to be an environmental hazard. Manual BP is also subject to measurement error on the part of the physician/nurse and patient-related anxiety which can result in poor quality BP measurements and office-induced (white coat) ...

INTRODUCTION: As several international guidelines on hypertension have now recommended, singlepill/fixed-dose combination antihypertensive therapies may be particularly beneficial as firstline therapy in high-risk patients, in whom more rapid and pronounced blood pressure (BP) control is desired. Upon the single-pill combination of amlodipine and valsartan becoming available, the authors conducted this ...
