Background: Blunt abdominal trauma (BAT) is physical injury caused by transfer of
energy to and within the person involved by non-penetrative mechanism to the
abdomen. BAT remains one of the commonest causes of morbidity and mortality in
patients with multiple injuries. Three mechanisms are involved, deceleration, crushing
and compression. MTRH handles a significant proportion of these patients and local
data is not available on their characteristics, management and outcome. This study
was therefore necessary to generate MTRH data which will form the baseline in
management of patients with BAT.
Objective: To determine the characteristics, management and outcome of patients
with blunt abdominal trauma at the MTRH.
Methods: The study was carried out at the emergency department and surgical wards
at MTRH. The study included Patients who presented with blunt abdominal trauma
and met the inclusion criteria at the MTRH between October 2013 and September
2014.This was an observational cross sectional study that used the consecutive
sampling technique. A total of 34 patients met the inclusion criteria and were all
included. Data was collected using a standardized questionnaire, clinical examinations
and review of medical records. The data was analyzed and presented in form of
percentages and ratios.
Results: A total of 34 patients, (29 males, 5 females) were studied, with a male to
female ratio of 6:1.A median age of 29yrs (IQR 13, 36) with a range of 3yrs to 65yrs.
Majority of patients 19 (55.9%) presented to the hospital more than 12hrs after injury.
The commonest mechanism of injury was Road traffic accident 16 (46.1%) and they
comprised of 8 (23.5%) motor bike accidents 6 (17.6 %) public service vehicles and 2
(5.9 %) personal vehicles while the spleen and mesentery were the commonest
location of injury 13 (38.3%). Majority of patients 19(55.9%) presented to hospital
more than 12 hours after injury. During presentation 30 (88.2%) patients were
hemodynamically stable. The main presentation was abdominal pain 34 (100%) and
vomiting 11(32.4%). Nausea was the least presentation 3 (8.9%).Tenderness and
guarding were the main signs at 31(91.8%) and 12 (35.3%) of patients respectively. A
total of 16 patients underwent laparotomy giving an operative management rate of
47.1%. Non operative management rate of 53%with a non-operative management
failure rate of 11.1%. Complications occurred in 4 patients giving a complication rate
of 11.8%. An overall mortality of 2.9% was observed in this study and this was
attributed to multiple injuries, delayed presentation and a low Glasgow coma scale.
Conclusion: Road traffic accident is the leading cause of blunt abdominal trauma at
MTRH with the spleen and mesentery as the commonest injured intra-abdominal
organs. Late presentation and multiple injuries were associated with poor outcome in
patients with blunt abdominal trauma.
Recommendation: Creation of public awareness on the importance of early
presentation to hospital after BAT. Timely diagnosis and management of blunt
abdominal trauma should be encouraged to reduce on morbidity and mortality. Nonoperative
mode of management to be encouraged. |
