Esmarch Bandages, Simple Leg Elevation
Conditions
Brief summary
To compare the adequacy of exsanguination in the surgical field between the use of the Esmarch bandages elevation and the simple leg elevation.
Interventions
OTHEREsmarch bandages
Esmarch bandage (also known as Esmarch's bandage for surgical haemostasis or Esmarch's tourniquet) in its modern form is a narrow (5 to 10 cm wide) soft rubber bandage that is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet.
OTHERsimple leg elevation
simple leg elevation 45 degree for 2 minutes is used to expel venous blood from a limb

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fromme-Boezaart surgical field scale | Immediate after surgery | Fromme-Boezaart surgical field scale is visual assessment of surgical field using a 6-point scale (min=0, max=5) 0 mean No bleeding 1. mean Slight bleeding ; no suctioning of blood required 2. mean Slight bleeding ; occasional suctioning required. Surgical field not threatened 3. mean Slight bleeding ; frequent suctioning required. Bleeding threatens surgical filed a few seconds after suction is removed 4. mean Moderate bleeding ; frequent suctioning required. Bleeding threatens surgical field directly after suction is removed 5. mean Severe bleeding ; constant suctioning required. Bleeding appears faster than can be removed by suction. Surgical field severely threatened and surgery not possible 0=best possible operating conditions and dryness of the surgical field; 5= worst possible conditions |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Numerical rating scale: NRS at 24 hrs | 24 hours after surgery | NRS is a pain intensity assessment of patients using a 11 point scale (min=0, max=10) 0=no pain 10= worst pain |
| Numerical rating scale: NRS at 72 hrs | 72 hours after surgery | NRS is a pain intensity assessment of patients using a 11 point scale (min=0, max=10) 0=no pain 10= worst pain |
