INTRODUCTION Postoperative nausea and vomiting (PONV) is the most common and unpleasant postoperative complication. There is much controversy on preoperative fluid therapy. The aim of this study was to examine the effect of crystalloid fluid (Ringer solution) versus colloid (Haemaccel solution) on the incidence of postoperative nausea and vomiting in patients receiving spinal anesthesia. METH...

The goal of this study was to assess the effect of extracellular glucose and K+ ((K)o) on the intracellular osmolyte content and cell volume maintenance and regulation in a human embryonic kidney cell line (tsA201a). Cell volume maintenance was studied by isotonic (313 +/- 5 mOsm) replacement of culture media by a glucose-free Ringer solution containing (in mM) 0, 3, 6, or 10 K+. Cell volume re...

The correlation between gap junction morphology and the state of electrical coupling was investigated in the frog auricle, which presents an atypical gap-junction organization. Electrical uncoupling of the tissue was achieved by perfusion with CO2-saturated Ringer medium. The tissue was fixed with glutaraldehyde and freeze-fractured before and during the application of CO2-saturated Ringer medi...

BACKGROUND Though hypertonic and isotonic crystalloids are used nowadays in resuscitating patients in hemorrhagic shock, yet there is no sufficient data in support of either. The aim of this study was to compare the hemodynamic effects of hypertonic saline 5% and lactated ringer solutions when used for the resuscitation of patients in hemorrhagic shock. METHODS In a double-blinded randomized ...

BACKGROUND/AIMS To compare two intraocular irrigating solutions, Balanced Salt Solution Plus (BSS Plus) versus Lactated Ringer's (Ringer), for the preservation of corneal integrity after phacoemulsification. METHODS 110 patients undergoing phacoemulsification were randomised to either BSS Plus (n=55) or Ringer (n=55) as the irrigating solution. Patients were examined at baseline and at 1, 8, ...

Procaine, cocaine, pyribenzamine, antistine, and phosphate decrease the uptake of water by frog sartorii in a Ringer solution in which potassium has been substituted for sodium; all but the last two leave the swelling in hypotonic Ringer practically unaltered. They also decrease the depolarizing action of potassium. These effects are considered indicative of reduced membrane permeability to pot...
