Effect of topical magnesium sulphate dressing on thrombophlebitis among patients with intravenous cannulation: a quasi-experimental study

Background Thrombophlebitis is a common complication of intravenous (IV) cannulation, characterized by pain, redness, swelling, induration, and warmth along the vein. It increases patient discomfort, prolongs hospital stay, and may lead to serious complications if untreated. Topical magnesium sulphate has anti-inflammatory and osmotic properties that may help reduce local inflammation. This study aimed to evaluate the effectiveness of topical magnesium sulphate dressing on thrombophlebitis among hospitalized patients.

Methods A quasi-experimental one group pretest–posttest design was adopted in a tertiary care hospital. Patients diagnosed with thrombophlebitis were recruited using purposive sampling and divided equally into experimental and control groups. A structured thrombophlebitis assessment scale was used to measure severity (pain, redness, swelling, induration, warmth). The experimental group received topical magnesium sulphate dressing, while the control group received routine hospital care. Data were analyzed using descriptive and inferential statistics including paired and unpaired tests and chi-square test.

Results The experimental group demonstrated a statistically significant reduction in mean thrombophlebitis scores after intervention compared to pretest scores (p<0.05). Posttest comparison between groups showed a significant difference favoring the experimental group. Selected demographic variables showed significant association with severity.

Conclusions Topical magnesium sulphate dressing was effective in reducing thrombophlebitis severity. It can be recommended as a simple, cost-effective nursing intervention in clinical settings.
