Insights

Cold Application, Manual Pressure, and Shot Blocker effectively reduce pain and swelling from pediatric intramuscular (IM) injections. These simple, low-cost methods can improve children's injection experiences.

Area of Science:

  • Pediatric healthcare
  • Pain management
  • Injection techniques

Background:

  • Intramuscular (IM) injections are common in pediatric care but cause pain and distress.
  • Non-pharmacological methods like Cold Application, Manual Pressure, and Shot Blocker aim to reduce injection discomfort.
  • This study evaluated these methods against standard procedures for pain and adverse effects.

Purpose of the Study:

  • To compare the effectiveness of Cold Application, Manual Pressure, and Shot Blocker against a standard procedure in managing pain and swelling from pediatric IM injections.
  • To assess the impact of these interventions on pain perception, swelling, redness, tenderness, and lump formation.

Main Methods:

  • A randomized controlled trial involving 40 children aged 9-11 years.
  • Participants were assigned to Cold Application, Manual Pressure, Shot Blocker, or Control (Standard Procedure) groups.
  • Pain was measured using the Wong-Baker Faces Pain Scale (FACES) and a 0-10 Pain Rating Scale; physical effects were assessed via an observation checklist. Data were analyzed using Chi-square tests and ANOVA.

Main Results:

  • Manual Pressure and Shot Blocker groups reported significantly less pain than the Control Group.
  • Cold Application and Shot Blocker groups showed significantly reduced swelling.
  • No significant differences were observed in redness or tenderness, and no lumps formed.

Conclusions:

  • Cold Application, Manual Pressure, and Shot Blocker are effective, low-cost strategies for minimizing pain and swelling during pediatric IM injections.
  • These techniques can be integrated into routine practice by healthcare providers, schools, and community health centers.
  • Further multicenter trials are recommended to investigate long-term outcomes, including compliance and psychological well-being.
