ABSTRACT
Introduction: Hip trauma is a
debilitating event that leads to a major limitation in patient’s functional
ability. The incidence of hip fractures increases with advancing age and are
more common in old age individuals. Closed-suction drainage has been routinely
used in total hip arthroplasty to prevent hematoma formation and surgical site
infections (SSI).
Objective: To compare the
frequency of surgical site infections in patients undergoing hip surgery with
closed suction drain placed at surgical site and without drain.
Study Design: Randomized controlled
trial.
Place and Duration: The study was
completed at department of Orthopedic Surgery Unit III, Bolan Medical College
Hospital Quetta, Pakistan. The duration of study was from 1-April-2016 to
31-October-2017.
Subjects and Methods: A total number of 176
patients who underwent hip arthroplasty were included in this study. Group A
(n=88) patients underwent hip surgery with placement of drain and Group B
patients underwent hip surgery without the placement of drains. Data analysis
was carried out using SPSS v20.0. Chi-square test was applied to compare
surgical site infections in drain group and without drain group. Effect
modifiers were controlled by stratification. Post stratification Chi-square
test was applied taking P-value <0.05 as significant.
Results: The mean age of
patients in this study was 42.26 (SD 9.86) years. There were 135 males (76.7%)
patients in this study and 41 (23.3%) female patients. The mean duration of
fracture was 39.41 (SD 7.74) days. There were 63 (35.8%) patients who presented
with greater/lesser trochanteric fractures, 64 (36.4%) presented with
sub-trochanteric fractures and 49 (27.8%) were presented with
inter-trochanteric fractures. SSIs occurred in 7 patients in whom drain was inserted
after surgery and in only 2 patients in whom drain was not inserted (p-value
0.08). There was no effect of confounder variables on the occurrence of SSIs.
Conclusion: The risk of surgical
site infections is same in patients undergoing hip surgery with closed suction
drain placed at surgical site and without drain.
