Hypertonic saline prehydration before spinal anaesthesia

Hypertonic saline prehydration in patients undergoing transurethral resection of the prostate under spinal anaesthesia.

Thirty-three patients undergoing elective transurethral resection of the prostate were allocated randomly to receive either 0.9% isotonic saline 7 ml kg-1 (16 patients), or 3% hypertonic saline 7 ml kg-1 (17 patients) as a preload before spinal anaesthesia. After spinal anaesthesia, the incidence of systolic arterial pressure < 75% of control value was greater in the normal saline group than in...

Effects of Hypertonic Saline (7.5%) on Haemodynamics and Extracellular Water Volumes after Coronary Artery Bypass Grafting and before Spinal Anaesthesia

The comparison of hypertonic saline (7.5%) and normal saline (0.9%) for initial fluid administration before spinal anesthesia.

Hypertonic saline can be used for initial fluid administration before spinal anesthesia. It is effective in small-volume fluid resuscitation. This randomized double-blinded study compared the effects of 7.5% hypertonic saline (HS) and 0.9% normal saline (NS) in doses containing 2 mmol/kg of sodium in 40 ASA physical status I-II patients undergoing arthroscopy or other lower limb surgery under s...

Hypertonic saline and stroke.

Cytotoxic brain edema—swelling of nerve and glial cells—is among the very early pathophysiologic sequelae of focal cerebral ischemia. Once cell swelling has exhausted the cerebral compliance, intracranial pressure increases and, thereby, causes secondary ischemia. Hypertonic solutions, mannitol in particular, have long been used to reduce intracranial pressure. More recently, hypertonic saline ...

Hypertonic saline for craniotomy?

IN this issue of ANESTHESIOLOGY, Rozet et al. present the findings of a comprehensive study comparing two hyperosmolar agents, hypertonic saline (HS) and mannitol, for brain relaxation during craniotomy. This work calls into question whether sufficient information is now available to advocate substitution of mannitol with HS to promote brain relaxation during routine craniotomy. It was discover...
