The use of HFOV for the treatment of CDH has proved to be a valuable technique for pre-operative stabilisation and for intra- and postoperative respiratory treatment, above all for newborns with CDH.
The chances of predicting CDH outcome are fairly high. During prenatal age, only a few findings may be obtained. Conversely, many postnatal indexes and scores can reliably predict such outcome.
Although longer follow-up to evaluate continence is to come, laparoscopically assisted anorectal pull-through should be considered for the correction of the high imperforate anus and, according to our experience, it represents the gold standard. It offers the advantage of good visualization of the fistula and the surrounding structures and minimally invasive abdominal and perineal wounds. With the laparoscopic Peña stimulator the direct observation of the contraction of the puborectalis sling allows an evaluation of the functional contractility and an accurate colonic pullthrough in the center of the muscle complex.
Neonatal CDH with a postero-lateral diaphragmatic defect allows the NAVA catheter to obtain a correct EAdi signal and develop a viable NAVA ventilation. The lower risk of lung injury in NAVA appears compatible with current ventilatory strategies considered useful in CDH.
We examined cardiovascular changes associated with intra-abdominal insufflation in 20 children (mean age 6.1+/-4.7 years, ASA physical status I or II) undergoing laparoscopic surgery with general anaesthesia using echocardiography with a transthoracic approach. Intra-abdominal pressure never exceeded 10 mmHg. Systolic blood pressure, diastolic blood pressure, endtidal CO2, peak, and mean airway pressure increased during intra-abdominal insufflation (P < 0.001). Pneumoperitoneum was associated with increases (P<0.001) in left ventricular enddiastolic volume, left ventricular end-systolic volume and left ventricular endsystolic meridional wall stress. In addition, before, during and after intra-abdominal insufflation, left ventricular fractional shortening and left ventricular ejection fraction, underwent slight, insignificant changes. Pneumoperitoneum in children has a major impact on cardiac volumes and function, mainly through the effect on ventricular load conditions. The sharp increase in intra-abdominal pressure affects both preload and afterload, while systolic cardiac performance remains unchanged.
We report a 5-year-old child with pancreatic trauma from a blunt abdominal injury that was monitored with contrast-enhanced sonography. Unenhanced US failed to demonstrate the abnormality that was recognized by CT and MRI. The injury was well demonstrated by contrast-enhanced US which was therefore used for follow-up until its healing.
Tracheal agenesis is a potentially lethal congenital anomaly, appearing only at birth. We describe a newborn preterm infant who presented with immediate respiratory distress and no audible cry. There was almost complete tracheal agenesis with a very short segment of distal trachea (only two tracheal rings) arising from the anterior wall of the esophagus, before dividing into the mainstem bronchi. The anomaly was unsuspected prenatally, as the scan showed pyloric atresia and complex congenital cardiac disease. Despite the patient's difficult course, with correction of the rare-associated malformations (cardiac and gastrointestinal tract anomalies), the fact that the child is lively and neurologically normal for her age, requires that we now consider the patency of the airway and the possibility of surgical correction, in accordance with a good quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
