Introduction: This study was undertaken to evaluate LOP (lowest occlusion pressure) is superior to the other ways of usage of Pneumatic Tourniquets in Orthopaedics surgery i.e. Fixed and Systolic BP variant.
Materials and Method: 120 cases of both upper and lower limbs operated from period September 2013 to October 2015 are randomly included in the study after full filling the inclusion and exclusion criteria and managed using Fixed, Systolic BP and LOP, each of the groups included 40 cases and results were analysed according to final outcome using Ishii et al. grading, VAS Score criteria.
Results: In our study 120 cases managed by LOP has a better result when compared to fixed variant and Systolic BP variant in terms of less pressure needed to keep tourniquet, good operative field, pain score (VAS) at tourniquet application region and skin injury(reddening). Bloodless field was excellent in 33 patients {[14 (35%) in LOP, 9(22.5%) in Systemic and 10 (25%) in Fixed Tourniquet variant. Among 120 patients, 11 (27.5%), 35 (87.5%) and 40 (100%) patients had experienced Skin abrasions/ Flaring were observed in the patient who underwent LOP, systemic and Fixed Tourniquet respectively. But no complications like compartment syndrome, deep vein disorder, paresis, nerve injury has occurred before and after surgery.
Conclusion: LOP is superior to all other ways of Tourniquet in terms of less pressure needed for elevating tourniquet, Good operative (bloodless) field, no skin abrasions.
