In endoscopic neurosurgery problems with haemostasis due to poor access exist. We have developed a system which allows the delivery of a variety of haemostatic agents in a more efficacious manner. The system has been used successfully in endoscopic skull base surgery and endoscopic surgery within the parenchyma of the brain using tube systems.

A 24-year-old primigravida presented with subacute ectopic pregnancy and had salpingectomy for a ruptured tubal pregnancy involving the ampullary portion of the left fallopian tube. Post-operative follow-up revealed continuing symptoms of pregnancy and increasing uterine size. A diagnosis of multiple pregnancy was confirmed by abdominal ultrasonography. The patient was managed to term and had n...

Introduction Percutaneous endoscopic gastrostomy (PEG) has becoming the most common way of feeding patients who cannot take adequate oral nutrition in the intensive care unit (ICU). According to ESPEN guidelines after complicationfree placement of a PEG system,delivery of nutrients via the tube can commence within 1 hour. But traditionally many clinicians are waiting 24 or more hours to start f...

In order to use tracheal gas insufflation (TGI) in a safe and effective manner, it is important to understand potential interactions between TGI and the mechanical ventilator that may impact upon gas delivery and carbon dioxide (CO2) elimination. Furthermore, potentially serious complications secondary to insufflation of cool, dry gas directly into the airway and the possibility of tube occlusi...

The male gametophytes of gymnosperms are characterized by the diversities in pollen morphology, cellular composition and pattern of cell division, pollen tube morphology, sperm delivery, growth pattern through the ovule and nucellus, and pollen tube wall composition both within and among the four living orders, i.e., Cycadales, Ginkgoales, Coniferales, and Gnetales. At dehiscence, gymnosperm po...

The current state of commercially available needle-free liquid jet injectors for drug delivery offers no way controlling the output pressure device in real time, as driving mechanism these provides a fixed profile. In order to improve efficiency well precision targeted tissue depth, it is necessary develop power source that can accurately control plunger velocity. duration injection vary from 1...

OBJECTIVE To determine the effect of endotracheal-tube cuff deflation on airflow and F(IO2) during high-frequency percussive ventilation (HFPV), and explore methods of correcting the cuff-deflation-associated decrease in mean airway pressure and F(IO2) at the carina. METHODS Using a mechanical lung model in our respiratory research laboratory, we measured circuit pressure near the connection ...
