weaning ultrasound

Sara I Williams, R Luzbel de la Sota
Ultrasonography was used to study follicular dynamics from the beginning of estrus to ovulation in pubertal gilts and post-weaning sows. Ultrasound turned out to be a useful tool to determine patterns of growth of preovulatory follicles, to predict ovulation time, and to design protocols for fixed time insemination.

Diaphragm function is crucial for patient outcome in the ICU setting and during the treatment period. The occurrence of an insufficiency of the respiratory pump, which is predominantly formed by the diaphragm, may result in intubation after failure of noninvasive ventilation. Especially patients suffering from chronic obstructive pulmonary disease are in danger of hypercapnic respiratory failure. Changes in biomechanical properties and fiber texture of the diaphragm are further cofactors directly leading to a need for intubation and mechanical ventilation...

BACKGROUND: We report the case of a giant intrathyroidal parathyroid adenoma weighing 59 g in a young woman presenting acutely with severe hypercalcemia requiring correction and adequate preoperative management prior to surgery. Parathyroid adenomas account for 85 % of cases of primary hyperparathyroidism. Those weighing more than 3.5g are classified as giant parathyroid adenomas. There are only 25 cases of parathyroid adenomas weighing over 30g reported in the literature. With the wide availability of biochemical screening tests in Western countries, mildly elevated calcium levels are often discovered incidentally...

BACKGROUND: Diaphragmatic dysfunction is often underdiagnosed and is among the risk factors for failed weaning. The purpose of this study was to determine the prevalence of diaphragmatic dysfunction diagnosed by B-mode ultrasonography and to determine whether prolonged weaning subjects with diaphragmatic dysfunction have increased duration of mechanical ventilation compared with those without diaphragmatic dysfunction. METHODS: This was a prospective observational study in mechanically ventilated subjects who failed ≥3 spontaneous breathing trials or required >7 d of weaning after the first spontaneous breathing trial...

PURPOSE: To assess the ability of diaphragmatic ultrasound (US) to predict weaning failure in mechanically ventilated patients undergoing a first spontaneous breathing trial (SBT). METHODS: During a 4-month period, 67 consecutive patients eligible for a first SBT underwent US measurements of maximal diaphragmatic excursion (MDE) by a right anterior subcostal approach. Weaning failure was defined as either the failure of SBT or the need for resumption of ventilatory support for acute respiratory failure or death within 48h following successful extubation...

PURPOSE: Diaphragmatic dysfunction (DD) has a high incidence in critically ill patients and is an under-recognized cause of respiratory failure and prolonged weaning from mechanical ventilation. Among different methods to assess diaphragmatic function, diaphragm ultrasonography (DU) is noninvasive, rapid, and easy to perform at the bedside. We systematically reviewed the current literature assessing the usefulness and accuracy of DU in intensive care unit (ICU) patients. METHODS: Pubmed, Cochrane Database of Systematic Reviews, Embase, Scopus, and Google Scholar Databases were searched for pertinent studies...

BACKGROUND: Cushing's syndrome is rare during pregnancy and more commonly due to adrenal pathology, in contrast to the non-pregnant population. Increased levels of cortisol-binding globulin and placental production of corticotropin-releasing hormone and adrenocorticotropic hormone complicate the diagnostic strategies usually employed. CASE: A 32-year-old G1P0 at 15/40 gestation presented with severe peripheral oedema and excessive weight gain. Examination revealed pitting oedema to the abdominal wall, wide violaceous striae, moon facies and acne...

Rationale Ventilator-induced Diaphragm Dysfunction is a significant contributor to weaning difficulty in ventilated critically ill patients. It has been hypothesized that electrically pacing the diaphragm during mechanical ventilation could reduce diaphragm dysfunction. Objectives We tested a novel, central line catheter-based, transvenous phrenic nerve pacing therapy for protecting the diaphragm in sedated and ventilated pigs. Methods Eighteen Yorkshire pigs were studied. Six pigs were sedated and mechanically ventilated for 2...

PURPOSE: Ultrasonographic assessment of diaphragm function with patients on low levels of pressure support (PS) predicts extubation outcomes, but similar information regarding extubation success under other conditions is lacking. The purpose of this study was to determine whether ultrasound (US) measurements of the diaphragm made on various levels of PS can predict time until successful extubation. METHODS: Fifty-six intubated patients underwent ultrasound of the right hemidiaphragm during a PS wean at varying levels of pressure support (PS 5/5 cm of H2O, 10/5 cm of H2O, and 15/5 cm of H2O)...

Reduced summer farrowing rates may be due to inadequate corpora luteal (CL) support. Porcine CL become dependent on LH from 12 d of pregnancy and the embryonic estrogen signal for maternal recognition of pregnancy (MRP) is initiated at about 11-12 d after insemination. We hypothesised that injection of the LH analogue human chorionic gonadotropin (hCG) would induce growth of estrogenic follicles and, by mimicking the signal for MRP and stimulating progesterone secretion, increase primiparous sow fertility. In Experiment 1, during a 28 d lactation 53 mixed parity sows were full-fed either throughout lactation (n=16) or until 18 d and then feed restricted during the last 10 d of lactation (n=36)...

BACKGROUND: Breast engorgement is a painful condition affecting large numbers of women in the early postpartum period. It may lead to premature weaning, cracked nipples, mastitis and breast abscess. Various forms of treatment for engorgement have been studied but so far little evidence has been found on an effective intervention. OBJECTIVES: This is an update of a systematic review first published by Snowden et al. in 2001 and subsequently published in 2010. The objective of this update is to seek new information on the best forms of treatment for breast engorgement in lactating women...

INTRODUCTION: Mechanical ventilation is a therapy for vital support used in a significant proportion of critically ill patients. The right time to successfully discontinue this therapy is a challenge for the intensive care specialist. For this reason it is still a subject for research. The echocardiographic evaluation of the diastolic dysfunction, the diaphragm, and the lung have become an invaluable tool for weaning from mechanical ventilation protocols, especially in patients with difficult or prolonged weaning from mechanical ventilation...

BACKGROUND: Life-threatening bleeding caused by liver injury due to chest compressions is a rare complication in otherwise successful cardiopulmonary resuscitation. Surgical intervention has been suggested to achieve bleeding control; however, reported mortality is high. In this report, we present a brief literature review and a case report in which use of a less invasive strategy was followed by an uneventful recovery. CASE PRESENTATION: A 37-year-old white woman was admitted after out-of-hospital cardiac arrest...

The endotracheal balloon catheter (A-view®) is a device developed to locate atherosclerotic plaques of the ascending aorta (AA) in cardiac surgery to prevent stroke. The saline-filled balloon is located in the trachea and combines the advantages of transoesophageal echocardiography (e.g. used before performing the sternotomy) and intraoperative epiaortic ultrasound scanning (e.g. complete view of the AA). We report the first severe complication after the use of A-view®. This is a case of a 66-year old woman who underwent elective myocardial revascularization complicated by an intraoperative iatrogenic tracheal rupture of 6 cm, after uncomplicated intubation and the use of an endotracheal balloon catheter (A-view®), which required direct surgical repair with a posterolateral thoracotomy after the myocardial revascularization was completed, weaning from bypass and closure of the median sternotomy...
