Post-weaning performance of piglets from systems where lactation is disrupted (e.g. from multisuckling systems) is superior to conventionally reared piglets. The objective of this study was to establish whether restricted growth prior to weaning caused by disruption of suckling was an important factor in post-weaning performance and also whether there were related changes in gastro-intestinal d...

RATIONALE AND OBJECTIVES Duration of weaning from mechanical ventilation may be reduced by the use of a systematic approach. We assessed whether a closed-loop knowledge-based algorithm introduced in a ventilator to act as a computer-driven weaning protocol can improve patient outcomes as compared with usual care. METHODS AND MEASUREMENTS We conducted a multicenter randomized controlled study ...

BACKGROUND For weaning patients from prolonged mechanical ventilation, we previously designed a respiratory-therapist-implemented weaning protocol that decreased median weaning time from 29 days to 17 days. An acceleration step at the start of the protocol allowed patients with a rapid shallow breathing index (RSBI) of < or = 80 to advance directly to spontaneous breathing trials (SBTs). METH...

AIMS To assess compliance with Department of Health guidelines on weaning practice in a representative sample of 127 infants from Glasgow, and to identify factors influencing timing of weaning. METHODS Questionnaires on feeding and weaning were completed during home visits. Ninety eight mothers completed a further questionnaire on attitudes to weaning. RESULTS Median age at introduction of ...

BACKGROUND The CO2 response test measures the hypercapnic drive response (which is defined as the ratio of the change in airway-occlusion pressure 0.1 s after the start of inspiratory flow [ΔP(0.1)] to the change in P(aCO2) [ΔP(aCO2)]), and the hypercapnic ventilatory response (which is defined as the ratio of the change in minute volume to ΔP(aCO2)). OBJECTIVE In mechanically ventilated pati...

introduction  mechanical ventilation may be lifesaving intervention,it can be associated with complications,thus,successful weaning is constitutive.one of the factors which is  important in successful weaning is  method of weaning. it is shown that  weaning is conducted successfully by using spontaneous breathing trial (sbt) through t-piece and pressure support (ps) ventilation.but few studies ...

Data from 158 predominantly Angus fall-calving beef cows were used in 4 consecutive years to determine the effects of weaning date and cow age class on cow and calf performance. Treatments were arranged in a 2 x 2 factorial with 2 weaning dates and 2 age classes (young cows or=4 yr). Weaning dates were 1) normal weaning in mid-April at 210 d of age (NW) and 2) late wea...

Background Weaning failure is a crucial hindrance in critically ill patients. Rapid shallow breathing index (RSBI), a well-known weaning index, has some limitations in predicting weaning outcomes. A new weaning index using point-of-care ultrasound with diaphragmic thickening fraction (DTF) has potential benefits for improving weaning success. The aim of this study was to evaluate the efficacy o...

INTRODUCTION A recent meta-analysis showed that weaning with SmartCare™ (Dräger, Lübeck, Germany) significantly decreased weaning time in critically ill patients. However, its utility compared with respiratory physiotherapist-protocolized weaning is still a matter of debate. We hypothesized that weaning with SmartCare™ would be as effective as respiratory physiotherapy-driven weaning in critica...

Early weaning is used to advance postpartum ovulation in beef cows, but triggers a stress response, affecting cows' and calves' welfare. Our aim was to compare the response to early weaning in multiparous and primiparous cows. Seventy-one days after birth, calves from 14 primiparous and 11 multiparous cows were weaned. Since birth, cow's body weight (BW), body condition (BC), milk yield and cal...
