the data were collected from 1992 to 2009 in burri, white boni and black boni sheep maintained at the regional research station in the central highlands of yemen. data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. the least square means for body weights (bw) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

Ventilator weaning protocols have the potential to expedite the weaning process and have been shown to reduce weaning time and the duration of mechanical ventilation in several studies. However, other studies have found no benefits from weaning protocols, and they may be particularly superfluous in highly staffed and structured intensive care units. Furthermore, for a protocol to improve outcom...

Experiments were undertaken to investigate whether a hypersensitivity response to dietary antigen might be a predisposing factor in the aetiology of post weaning diarrhoea. The results indicated that: 1. very small amounts of food given to baby pigs before weaning significantly increased the severity and accelerated the onset of the disease; 2. post weaning diarrhoea was dependent upon the pres...

BACKGROUND Therapist-implemented protocols have been used to extubate or wean patients in the ICU setting. Barlow Respiratory Hospital (BRH) functions as a center for weaning patients from prolonged mechanical ventilation (PMV) in the post-ICU setting of a long-term acute-care (LTAC) facility. A therapist-implemented patient-specific (TIPS) weaning protocol was developed at BRH to standardize w...

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 ...
