ABSTRACT:
Background: Save blood-save life is one of the (Red
Cross Society) slogans. Trauma is a physical wound caused by external force or
violence, a painful emotional experience. Trauma is a leading cause of death in
people between the ages of 18-45 years. It is the fourth leading cause of death
in the world. Traumatic injury is the leading cause of death worldwide among
persons between 18-45 years of age and accounts for 10% of all deaths. Applying appropriate hemorrhage control
techniques are of much help to reduce the mortality rates, tourniquet
was highly effectiveness to control external bleeding among trauma patients.
Objectives: The present study aimed to assess the effectiveness of
tourniquet on external bleeding among trauma patients.
Design: True-experimental design, where Posttest only with control
Group design was used.
Participants: 40 trauma patients were included in the study.
Methods: Random allocation sampling technique was used in the
study. Tourniquet was applied for an Experimental group (Exp) with external
bleeding with duration of 10 min, 15 min and 20 min in exp-I, II and III
respectively in three groups.
Results: The data was obtained by using a demographic proforma and revised trauma scale for trauma patients.
After intervention Results showed in control group exp-I only 40% of the external
bleeding was controlled, and there was 90% of the external bleeding control in
experimental group II and III. The calculated unpaired ‘t’
test value showed that there is significant effectiveness of tourniquet in 15
min and 20 min (t=2.62, t=3.896 and tv=2.021) on
external bleeding among trauma patients.
Conclusion: Tourniquet
is an effective technique to reduce the level of external bleeding among trauma
patients.
KEYWORDS: Trauma, External bleeding, Tourniquet.
INTRODUCTION:
Trauma
is a very serious injury to a person's body that creates unpleasant experience. Traumatic injury is the leading cause of death
worldwide among persons between 5 and 44 years of age and accounts for 10% of
all deaths. It is the fifth leading cause of death in the India, with
uncontrolled bleeding it leads to potentially preventable death. (Lewis, 2004)
United
Nations Organization, (2009), in its Global Status Report on Road Safety,
estimated that over 90% of the world’s fatalities on the roads occur due to
uncontrolled hemorrhage. Predicts that road traffic injuries will rise to
become the fifth leading cause of
death by 2030. At the same time,
injuries are considered one of the most avoidable health problems.
Bleeding is the loss of blood from
circulatory system. Improving our
ability to control bleeding may represent the next major hurdle in reducing
trauma mortality. Uncontrolled or severe bleeding can contribute to shock, circulatory disruption, or more
serious health consequences such as damage to tissues and major organs, which
can lead to death, (Hilbert P, 2012).
According
to Indian express (2008), The number of road accident
deaths per lakh of population which is 10.5 in India.
As many as 51% of all
deaths in the first 48 hours of
hospitalization are related to lack of homeostasis in the early period
which is a golden hour. World Health Statistics During the year 2010,
there were around 5 lakh road accidents, which
resulted in deaths of 134, 513 people and injured more than 5 lakh persons in India. These numbers translate into 1 road
accident every minute and 1 road accident death every four minutes. The loss to
the Indian economy due to fatalities and accident injuries estimated at 3% of
GDP in 2000-2010 is particularly due to severe bleeding of 53.1% of road
accident victims and were in the age group of 25 to 65 years in 2010, (WHO,
2010).
Severe
bleeding accounts for about one third of in-hospital deaths due to trauma. It
is an important contributory factor for other causes of death. The cause of
external hemorrhage can be varied depending on the setting in which the injury
has taken place. Some of these causes include, but are not limited to,
gunshots, stabbings, shrapnel, vehicle accidents and blasts. Failure to start
appropriate early management in bleeding trauma patients is a leading cause of
preventable death from trauma, (David Prieto-Merino,
2011).
Failures
to stop bleeding within the first 24 hours are almost uniformly fatal. You must
also recognize the type of bleeding, apply the appropriate hemorrhage control
techniques, understand the varying degrees of risk associated with types of
hemorrhage, and how to estimate blood loss, (Thomas J, 2011). External bleeding can result in severe of
blood loss with resultant shock and subsequent death. Injury can cause damage
to vital organs, painful, swelling, weakness, faintness, increased thirst,
dropping of blood pressure, dilated pupils, nausea and vomiting. Mainly noticed
signs are Massive blood loss and obvious signs and symptoms of shock, (Joyce M
black, 2006). In 2008, 800000
injury related deaths in Europe accounted for 8.3% of total deaths (WHO,
2006). Gujarat it
stands in fourth place per road injuries causing death. Gujarat leads in India
and as fast growing cities more accidents and among surat is leading city with trauma and road traffic
accidents. Applying
appropriate haemorrhage control techniques are of
much help to reduce the mortality rates due to massive bleeding. Techniques
such as apply fingertip pressure directly on the point of bleeding, elevation
of bleeding extremity, packing the wound with sterile dressing, direct hand
pressure, pressure points, splints, pressure splints, and tourniquet
application, (Moore FA,
2010)
A
tourniquet acts as a constricting or compressing device used to control venous
and arterial circulation to an extremity for a period of time. A tourniquet
represents a simple and efficient method for acute external hemorrhage control.
Tourniquet should be left in place until surgical control of bleeding is
achieved, (Holcomb, 2008).
Reported a systematic review and
Meta-analysis published randomized
controlled trials evaluating the efficacy of tourniquet in reducing blood loss
and transfusion in limb injury patients. The data were evaluated using the generic evaluation
tool designed by the Cochrane Bone, Joint and Muscle Trauma Group. We
identified 11 clinical trials which were suitable for detailed extraction of
data. A total of seven studies (comprising 350 patients) were eligible for the
blood loss outcome data. The use of tourniquet reduced intra-operative blood
loss by a mean of 104 ml (95% confidence interval (CI) −164 to −44,
p = 0.0006, heterogeneity ( 0%),
postoperative blood loss by a mean of 172 ml (95% CI −263 to −81, p
= 0.0002, heterogeneity ( 63%)
and total blood loss by a mean of 289 ml (95% CI −440 to −138, p
< 0.0002, heterogeneity (54%). tourniquet led to a significant reduction in
the proportion of patients requiring allogeneic blood
transfusion (risk difference −0.20, 95% CI −0.29 to −0.11, p
< 0.00001, I2 15%).
There were no significant complications among the study groups, (M. Sukeik, 2010).
Smith (2009), conducted a random-effects
meta-analysis study in Norfolk &
Norwich University Hospital, United Kingdom. This study compares the intra- and
post-operative outcomes of upper limb orthopaedic
surgical procedures performed with and without tourniquet assistance. A
systematic review was undertaken assessing the electronic databases Medline,
CINAHL, AMED and EMBASE. The evidence-base was critically appraised using the
Cochrane Bone, Joint and Muscle Trauma Group quality assessment tool. Study
heterogeneity was statistically tested using chi- square statistics. Where
appropriate random-effects meta-analysis was undertaken to pool results of
primary studies assessing mean difference of each outcome. Two studies
investigating 55 patients undergoing upper limb surgery were identified. The
limited findings suggest that the use of tourniquets will reduce 76% (i.e CI = 3.1, MD= 0.1) (P= <0.001). Therefore the
researcher is interested in application of tourniquet to control external
bleeding as it is a preventable by taking proper measures in right time which
is so called “GOLDEN HOUR”

Comparison
of mean, SD, and mean percentage of control and experimental group-I post test
scores reveals that, in control group post test the mean score was (9.4 ±
1.05), which is 78.3%, in experimental group-I post test the mean score was (9
± 0.24), which is 75%, showing a difference of 3.3 on reduction of external
bleeding. experimental group-II, post test the mean score was (10.7 ± 1.20),
which is 89.1%, showing a difference of 10.8 on reduction of external bleeding,
where as in experimental group-III, post test the mean score was (11.2 ± 1.05),
which is 93.3%, showing a difference of 15% on reduction of external bleeding.
It seems that tourniquet
was effective on external bleeding among trauma patients.
CONCLUSION:
·
In experimental
group I most of the trauma patients with external bleeding were males, in the
age group 18-27 years and 28-36 years, and lower limb injury.
·
In experimental
group II most of the trauma patients with external bleeding were males, in the
age group 37-45 years, and lower limb injury.
·
In experimental
group III most of the trauma patients with external bleeding were males, in the
age group 37-45 years, and had lower limb injury.
·
In control group
most of the trauma patients with external bleeding were males, in the age group
28-36 years, and had lower limb injury.
·
There was no
significant effectiveness of tourniquet on external bleeding among trauma
patients in control group with routine procedures and experimental group-I with
tourniquet after 10 minutes of time duration.
·
There was a mild
significant effectiveness of tourniquet on external bleeding among trauma
patients in experimental group-II (15 minutes).
·
There was a
moderate significant effectiveness of tourniquet on external bleeding among
trauma patients in experimental group-III (20 minutes).
·
There was no
significant association between post test scores on external bleeding among
experimental group and control group with their selected demographic variables
such as age in years, gender and site of bleeding.
