Effect of Hypericum Perforatum Oil on Ecchymosis and Pain

April 15, 2024 updated by: HATİCE DEMİRDAĞ, Uskudar University

Effect of Hypericum Perforatum Oil on Prevention Ecchymosis and Pain Associated With Subcutaneous Low Molecular Weight Heparin Injection: a Self-controlled Single-blind Study

Low molecular weight heparin is a drug with anticoagulant and antithrombotic effects. This drug is frequently administered subcutaneously to patients by nurses. Complications such as pain, ecchymosis and hematoma may commonly occur at the injection site. This study investigated the effect of Hypericum Perforatum oil in preventing pain and ecchymosis after subcutaneous injection low molecular weight heparin. This quasi-experimental and single blinded study was conducted with 160 patients in a coronary intensive care unit. The researcher nurse applied 5-6 drops of Hypericum Perforatum oil to one arm of the patients 2 hours before the injection. The other arm of the patient was considered as the control arm. A total of 320 injections were administered. The evaluation of the injection sites was performed by two other researchers at 48th hours. The data were analyzed using Wilcoxon and McNemar test.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Experimental: Hypericum Perforatum Oil group
This research is a self-controlled study. One injected arm of the patient will be assigned to the intervention group and the other arm to the control group. İn the experimental arm, the research nurse working in the Coronary Intensive Care unit (CICU) applied 5-6 drops of HP oil on one arm of the patient with a patting motion 2 hours before the injection. The area was left open for the oil to be absorbed. Only this nurse who administered the injection knows on which arm the oil was applied. The assessment of ecchymosis and pain at the injection site was performed by two other investigators at the 48th hour of the injection (Single blind).
Other: Topical hypericum perforatum oil intervention
The research nurse working in the CICU applied 5-6 drops of hypericum perforatum oil on one arm of the patient with a patting motion 2 hours before the injection. The area was left open for the oil to be absorbed. Only this nurse who administered the injection knows on which arm the oil was applied.
No Intervention: Control group
This research is a self-controlled study. One injected arm of the patient will be assigned to the intervention group and the other arm to the control group.In the control arm, no treatment was performed before injection.The assessment of ecchymosis and pain at the injection site was performed by two other investigators at the 48th hour of the injection (Single blind).

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain point
Time Frame: 48 hours after injection
The patient's pain was evaluated with Visual Analogue Scale (VAS) 48 hours after the injection. Visual Analogue Scale is a reliable pain assessment scale to determine the pain felt by patients at the injection site. The VAS is a self-report scale consisting of a horizontal line (10 cm long) with anchor points "no pain" and "worst possible pain". The patient is asked to mark the place on this line that best describes the intensity of pain. A marking of "0" means "no pain". Marking "10" means "'intolerable pain". In this way, the patient scores his/her pain between 1-10.
48 hours after injection
Ecchymosis
Time Frame: 48 hours after injection
Ecchymosis was evaluated at 48th hours after injection in the study. A transparent ruler that allows millimetric measurement was used to measure the ecchymosis at the injection site. The discoloration at the injection site was measured in millimeter. Ecchymosis was defined as an area of discolored skin of more than 2 mm appearing 48th hours after administration. The maximum horizontal extent (diameter) of the bruise was recorded regardless of whether the bruise was regular or uneven in shape at the time of measurement. According to previous studies, bruise size was analyzed according to 3 categories: no bruise (0-1 mm), small bruise (2-5 mm) and large bruise (>5 mm). In our study, bruises >2 mm in size was accepted as ecchymosis.
