Comparing the effectiveness of three pain relief methods for inserting a needle into the implanted venous access chemoport: A randomized controlled trial

Abstract

Aims: Effective methods for relieving pain in inserting a needle for chemotherapy in cancer patients have been studied. This study examined the pain relief effects during needle insertion into the implanted venous access chemoport by comparing three methods.

Methods: This randomized controlled trial included 120 cancer patients who were randomly assigned. The experimental groups received applications of lidocaine cream (n = 30), cryotherapy (n = 30) and cutaneous stimulation therapy (n = 30); the control group (n = 30) received routine care. Premeasurements and postmeasurements were evaluated using a visual analogue pain scale and nurses' careful observations of patients' pain behaviour checklists during needle insertion.

Results: Pain levels were reduced by all three interventions, with the level of relief depending on the type of application. All experimental groups showed significant reduction in pain compared with the control group. Lidocaine cream had the strongest effect, followed by cryotherapy and then cutaneous stimulation.

Conclusion: Lidocaine cream, cryotherapy and cutaneous stimulation therapy all reduced cancer patients' pain levels during insertion of an implanted central venous access chemoport needle. Nurses can apply cryotherapy and cutaneous stimulation therapy independently to reduce the pain associated with this procedure. Future studies should consider using these methods to control for any individual differences that may exist.
