Crystalloids Versus Colloids Versus Hypertonic Saline as a Co-load During Spinal Anesthesia.
A study testing Normal saline, hydroxyethyl starch and Hypertonic saline in people with Spinal Anaesthesia, run by National Cancer Institute, Egypt at 1 site in Egypt.
Trial summary
Spinal anesthesia is commonly accompanied by hypotension due to vasodilation that follows sympathetic blockade and decreased systemic vascular resistance. Prevention of hypotension is usually achieved through administration of fluids and vasopressors .There is an ongoing debate concerning both the proper fluid timing… Read more about this study

About this study
Official title: Crystalloids Versus Colloids Versus Hypertonic Saline Co-load During Spinal Anesthesia: Which is More Effective
Spinal anesthesia is commonly accompanied by hypotension due to vasodilation that follows sympathetic blockade and decreased systemic vascular resistance. Prevention of hypotension is usually achieved through administration of fluids and vasopressors .There is an ongoing debate concerning both the proper fluid timing, pre-load against co-load and fluid type crystalloids against colloids .This study aims at comparing the effectiveness of co-loading of crystalloids versus colloids versus hypertonic saline 3% in preventing hypotension induced by spinal anesthesia.
Read the detailed description
Spinal anesthesia is commonly accompanied by hypotension due to vasodilation that follows sympathetic blockade and decreased systemic vascular resistance. Prevention of hypotension is usually achieved through administration of fluids and vasopressors . Fluids are either administrated before initiation of spinal anesthesia which is defined as fluid pre-loading or at time of initiation of spinal anesthesia which is defined as fluid co-loading .There is an ongoing debate concerning both the proper fluid timing, pre-load against co-load and fluid type crystalloids against colloids. Fluid preloading with colloids appears to have superior effect on that of crystalloids as the later shows a shorter intravascular half-life. While both colloid and crystalloid co-loading show comparable results .Although crystalloid preloading has been the traditional regimen for long time, it failed to reduce the incidence of hypotension. This is because crystalloids rapidly distribute out of the intravascular compartment to the interstitial space. Superiority of fluid co-loading might be explained by decrease of the extravascular crystalloid redistribution secondary to the simultaneous vasodilatation response to sympathetic block.This study aims at comparing the effectiveness of co-loading of crystalloids versus colloids versus hypertonic saline 3% in preventing hypotension induced by spinal anesthesia.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hypotension (time frame: 3 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2018; AzTrials last refreshed its copy on 30 Oct 2026.
