Overview
Brief Summary
The goal of this clinical trial is to compare the effect of cold application at different periods of time on the occurrence of bruising, haematoma and pain in the subcutaneous low molecular weight heparin (LMWH) injected patients.
Detailed Description
The study was a single-blind randomised control trial. Patients were allocated randomly to three groups: (i) Cold was applied for two minutes before the injection in the first group (n=26); (ii) Cold was applied for 5 min before the injection in the second group (n=26); and (iii) control group (n=26). All participating patients were injected 40 mg enoxaparin sodium in 0.4 ml in the pre-filled syringes using standard LMWH injection protocol. Post-injection VAS (Visual Analogue Scale) assessment and assessment of the presence and size of bruise and haematoma were conducted at 48th and 72nd hours after the injections for all groups.

- •not to have any visual or auditory disorders
- •not to have any foreknown coagulation disorders
- •to have platelet, PTT and international normalized ratio (INR) values within the normal limits for beginning enoxaparin sodium injections

Exclusion Criteria

Outcomes
Primary Outcomes
Compare of the bruise sizes change of the patients at 48th and 72nd hours.
Time Frame: after 48th and 72nd hours from injection
If bruise developed after heparin injection, its size was measured 2 times at 48th and 72nd hours and recorded.
Compare of the bruise occurrence change at 48th and 72nd hours after the heparin injection.
Time Frame: after 48th and 72nd hours from injection
It was evaluated whether bruise occurred 2 times at 48th and 72nd hours after heparin injection.
Compare of the Visual Analogue Scale pain scores of the patients
Time Frame: after 1 minute from injection administration
The level of pain felt after the heparin injection administration was measured with the visual analogue scale. Visual Analogue Scale (VAS) was used to measure the extent of pain during the injection. VAS is widely used to measure the clinical symptoms such as pain, panic, depression, and fatigue. VAS consists of 100 mm on a horizontal line. On the scale "0" means no pain and "100" shows severe pain. The patients were asked to mark the extent of pain they had immediately after the subcutaneous injection on the scale with 'X'. The distance from "no pain" to the place that the patient has marked quantitatively represents the pain of the patient.
Secondary Outcomes
- Occurrence of haematoma at 48th and 72nd hours after the heparin injection.(after 48th and 72nd hours from injection)
