The low frequency cerebral blood flow velocity (CBFV) oscillations in neonates are commonly attributed to an under-dampened immature linear type cerebral autoregulation, and the 'instability' is regarded as causative for peri-intraventricular haemorrhage/periventricular leukomalacia. In contrast, oscillations susceptible to frequency entrainment are a fundamental part of the stable function of ...

BACKGROUND Hospital electrical power failure represents an important challenge in the intensive care unit. Despite the presence of backup generators, total electrical power failure may still occur. Life-support equipment should have a reliable internal battery to ensure patient safety. We tested the duration of operation of the internal battery of 4 intensive care ventilators. METHODS In our ...

In 1954, I was extremely fortunate to be appointed to Green Lane Hospital to provide technical assistance to an emergent cardiac surgical unit, the first such appointment in New Zealand. My background was in electronics and instead of servicing radar equipment, I found myself involved in a far more interesting and fascinating field. At that time, a small team headed by surgeon D. Robb (later Si...

A palpable dicrotic pulse was observed in 18 patients after open heart operation, usually after prosthetic replacement for aortic regurgitation (14 of 18 patients). Two patients had a ventricular septal defect, one had aortic stenosis, and one, mitral insufficiency. The ages of the patients ranged from 9 to 63 years, but the dicrotic pulse was more prominent and persisted longer in younger pati...

conclusions the result of this study indicated that nephrotoxicity rate among patients treated with vancomycin is under the influence of the poisoning by nephrotoxicants. higher vancomycin trough level was associated with increasing nephrotoxicity rate. results one hundred and fifty-four vap patients’ profiles were reviewed, of whom 110 were eligible. the median age was 33.50 (12 to 94) years a...

The surgical closure of patent ductus arteriosus (PDA) is provided more frequently in extremely low birth weight babies who are usually deemed unsuitable for pharmacological closure. We have adopted subaxillary mini-thoracotomy in order to lessen surgical trauma in these babies; and its clinical results were analyzed. From April 2004 to August 2008, out of 50 babies at the neonatal intensive ca...

Patient-ventilator asynchrony/dysynchrony is a mismatch between the patient and ventilator's delivered breaths ability of ventilator to meet demands. Any factor that alters harmony these two components produces asynchrony, which can cause discomfort an increase in patient's work breathing. Delayed cycling occurs when neural time less than mechanical ventilator. Keywords: ventilator, delayed cyc...

This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan province,center of Iran, close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study, first grinding circuit and its performance parameters are evaluated. Laboratory and corrected operating Bond work index subsequently were calcu...
