Some of the studies have shown that preloading
and co loading with colloid may be of more help to reduce the incidence of SIH and CVSE but the cost of colloid and risk of anaphylactic reaction with colloid do not make it a suitable and widely acceptable alternative of crystalloids (22).
The volume preloading
is not essential to prevent spinal induced hypotension during caesarean section.
After securing I.V access using 18G cannula, preloading
of Study group patients were started using 1 liter of ringer's lactate solution over a period of 15-20 min before spinal anesthesia whereas Patients in control group remained unpreloaded.
METHODOLOGY: A comparative study of volume preloading
prior to subarachnoid block in lower abdominal surgery with hetastarch (6%), polygelatin, ringer's lactate was undertaken after ethical committee clearance, institution approval and informed consent from the patients.
with hetastarch has been our standard regimen for elective CD for over two decades in our institution (10).
After 1 year, 14.0% of people in the preloading
group maintained long-term abstinence, compared with 11.3% in the control group.
He said: 'I don't want to bring the picture out yet, but those who said preloading
is not possible are not telling the truth.
Participants were randomized to either the control arm (893 participants) and received standard smoking cessation pharmacotherapy and behavioral support or to the preloading
arm (899 adults) who received the same treatment supplemented by four weeks of 21-mg nicotine patch use before quitting.
Two laboratory model tests, vacuum preloading
and geotextile tube tests, were carried out.
Some studies compared crystalloid preloading
to colloid preloading12.
* Using proven air-on-air preloading
in critical bearing elements improves turnaround and settling times over vacuum-preloaded designs.
