Abstract
The present study aimed to evaluate and compare single dilator percutaneous tracheostomy, multiple dilators percutaneous tracheostomy and surgical tracheostomy with regard to duration of procedure, incidence of complications, and outcome of tracheostomy.
A total of 48 ICU patients who were indicated for tracheostomy were randomly assigned for one of three equal groups: SPDT group, MPDT group and surgical tracheostomy group.
All of the three groups of the study were matched regarding demographic data, cause of ICU admission, cause of endotracheal intubation and reason for tracheostomy.
Tracheostomy for patients in the surgical group took significantly longer time when compared to patients in SPDT and MPDT groups. SPDT and MPDT were comparable regarding procedure time. This finding makes PDT adventitious and superior to surgical tracheostomy.
All techniques of tracheostomy were devoid of life threatening complications. Only one case in the surgical group was reported to have significant intra-tracheal hemorrhage to which surgical re-exploration was done for proper heamostasis.
Patients in the surgical group were intubated for significantly longer periods than these in SPDT, MPDT groups, while there was no statistically significant difference between SPDT and MPDT groups regarding days of Intubation Prior to tracheostomy.
Hemodynamic stability was noted among majority of patients in the three groups of the study throughout the duration of the procedure.
Tracheal and stomal closure following surgical tracheostomy was delayed when compared to both SPDT and MPDT techniques with no significant difference between both PDT techniques.
