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.
