A simple modification to the standard 'in-out' exchange transfusion technique is described which requires cannulation of the umbilical vein only, yet provides many of the theoretical and practical advantages of a 2-catheter arteriovenous technique. The advantages include a reduction of cardiovascular disturbance; a reduction of the inevitable pressure changes in the portal venous system (probab...
Mountain, K. R., and Campbell, D. G. (1970). Archives of Disease in Childhood, 45,134. Reliability ofoxygen tension measurements on arterialized capillary blood in the newborn. Samples of blood were obtained from newborn infants simultaneously from an umbilical artery catheter, an 'arterialized' heel, an unprepared heel, and from an 'arterialized' thumb. The correlation between the arterial oxy...
strict surgical asepsis, the use of transparent catheter (polyvinyl feeding tube with a rounded end and side holes) for umbilical catheterization was strongly suggested, as it enabled easy identification of the air bubbles that can cause of air embolism if pushed into the circulation. The clearance of blocked catheters (clots in the circulation) using pressure was strongly reprehended. In situa...
conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...
We induced percutaneous spinal cord injuries (SCI) using a balloon catheter in 45 rats and transplanted human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) at the injury site. Locomotor function was significantly improved in hUCB-MSCs transplanted groups. Quantitative ELISA of extract from entire injured spinal cord showed increased expression of brain-derived neurotrophic fac...
A 90-year-old wheelchair bound male was brought to the emergency department with complaints of worsening abdominal pain over the last 2-3 days. The patient also had difficulty in passing urine. Abdominal examination revealed tenderness in the umbilical and hypogastric area without rebound tenderness or guarding. Computed tomography (CT) of the abdomen showed a loop of colon interpositioned betw...
Caudal anaesthesia (CA) is epidural anaesthesia of the cauda equina roots in the sacral canal, accessed through the sacral hiatus. CA is a common paediatric regional technique that is quick to learn and easy to perform, with high success and low complication rates. CA provides high quality intraoperative and early postoperative analgesia for sub-umbilical surgery. In children, CA is most effect...
