Hypertonic saline solutions in shock resuscitation.
Hypertonic saline solutions (HSS) have several characteristics that may improve the survival of patients during the initial treatment of certain types of shock. The use of isotonic crystalloids for resuscitation has several limitations: large infusion volumes are needed to increase the intravascular space; these large volumes cannot be given rapidly; and the fluid rapidly redistributes througho...
متن کاملSaline solutions: the quest for fresh water.
Despite steady advances in the technology, desalination remains one of the most expensive ways to produce potable water. But as water scarcity forces communities to find new sources of drinking water, scientists are developing innovations that may soon make desalination a reasonable option for many more communities. The newest approach to desalination is membrane systems, which include reverse ...
متن کاملErythrocyte stability in ethanol-saline solutions.
Sir,—In a clinical evaluation of ethanol as an anaesthetic agent, Isaac and Dundee (1969) and Dundee and coworkers (1970) established that 8% w/v (10% v/v) ethanol in Hartmann's solution was the most satisfactory concentration for i.v. infusion in man and was associated with a low frequency of thrombophlebitis. Sanderson and co-workers (1970) confirmed that in vitro ethanol solutions in concent...
متن کاملComparative Efficacy of Hypertonic Saline and Normal Saline Solutions in Experimentally Induced Endotoxic Shock in Dogs
This study was contemplated to determine the comparative beneficial effects of hypertonic saline solution and sterile saline solution in induced endotoxic shock in dogs. For this purpose, 12 healthy Mongrel dogs were randomly divided into two equal groups (A and B). All the animals were induced endotoxaemia by slow intravenous administration of Escherichia coli endotoxins 0111:B4. Group A was t...
متن کاملMicrowave and Ultrasound Augmented Leaching of Complicated Zinc Oxide Ores in Ammonia and Ammonium Citrate Solutions
Recovery of zinc from low grade zinc oxide ore is attempted with ammonia and ammonium citrate solutions augmented by microwave roasting and ultrasound radiation. The influence of the ammonia-ammonium ratio, roasting temperature, ultrasound power, and leaching time were assessed on the recovery of zinc. A maximum zinc recovery of 88.57% could be achieved at a roasting temperature of 673 K, leach...
