The effect of cryotherapy application before versus after subcutaneous anticoagulant injection on pain intensity and hematoma formation: A quasi-experimental design.

ABSTRACT:

Objective

To investigate the effect of cryotherapy application before versus after subcutaneous anticoagulant injection (SCAI) on pain intensity and hematoma formation.

Methods

A quasi-experimental design was utilized. A convenient sample of 105 adult patients, who were admitted to one of the biggest teaching hospitals in Cairo and receiving SCAI, were recruited over a period of six months. Patients were randomly allocated into three groups: A Control group who received the routine hospital care (G1,n?=?35) and two intervention group who received cryotherapy for 5-min (G2: cryotherapy applied before SCAI, n?=?35; G3: cryotherapy applied after SCAI, n?=?35). Demographic and medical history data sheet, Pain Numeric Rating Scale and Hematoma Formation and Size Assessment Scale were used to collect the data.

Results

The pain intensity among the patients in the two intervention groups (G2: Median?=?1.0; G3: Median?=?0) was significantly lower than in the control group (G1, Median?=?3.0). No significant difference was found between G2 and G3(P?=?0.728). Applying cryotherapy after SCAI (G3) decreased the frequency of hematoma formation (48hrs?=?31.4% & 72hrs?=?28.5%) compared to applying it before injection (G2, 100%) or not applying it (G1, 100%). The size of hematoma in G3 was smaller than that in G2 (P?ConclusionApplying cryotherapy significantly decreased pain intensity and hematoma occurrence/size. Applying cryotherapy after injection was more effective in preventing hematoma formation and decreasing its size than applying it before injection.
