Tumours of the head and neck have been treated by a cytotoxic drug given via the arterial supply. A simple anaesthetic technique is described. Related problems are considered, such as difficulty in intubation, difficulty in assessing skin colour following the injection of dye, and acute respiratory obstruction after operation from reactionary oedema in the tumour. Indications for tracheostomy a...

Intravenous drug abuse unfortunately remains an extremely common problem worldwide, accounting for innumerable medical issues ranging from the transmission of human immunodeficiency virus (HIV) and other blood-borne diseases to skin necrosis to vasculitis to death [1]. We present a case of intra-arterial injection of alprazolam into the right femoral artery resulting in microembolization, acute...

To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...

Arterial cannulation is associated with complications including bacterial contamination, accidental intra-arterial injection and blood spillage. We performed a series of audits and experiments to gauge the potential for these, as well as assess the possible contribution of a new device, the Needle-Free Arterial Non-Injectable Connector (NIC), in reducing these risks. The NIC comprises a needle-...

Objectives: Drug injection carries with it many risks and therefore it is important to understand the initiating factors of injection and its origins. Thus,  the purpose of this study was to identify factors associated with the initiation of injection drug use among substance abusers. Methods:  Study method was a cross-sectional study. The research statistics universe constitutes a...

Introduction: Resistin, a complex multimeric structure which is secreted by adipose tissue and circulates in the blood, acts on the hypothalamus to increase sympathetic nerve activity, inhibit appetite and is associated with obesity, insulin resistance and cardiovascular disorders. In this study, we survey the cardiovascular effects of direct injection of resistin into specific cell group of th...
