Purpose: Gamma knife radiosurgery (GKR) requires frame positioning because the treatment target should be as close as possible to the center of the frame. The purpose of this study was to identify the level of pin-fixing (PFP) and removal pain (PRP), and the associated factors with the pain undergoing GKR.
Methods: A total of 116 patients who underwent GKR for their brain tumor were recruited from C University hospital located in H city, J province. The level of pain was measured by the 10 cm VAS.
Results: The level of PFP and PRP were 6.36 and 3.26 points, respectively. Step-wise multiple regressions found that the group who have not perceived numbness after applying 5% EMLA cream was the highest associated factor with PFP, following the time from lidocaine injection to pin-fixation, which explained 21% of total variance of the level of PFP. On the other hand, a group who did not perceive numbness after applying 10% lidocaine spray was the highest factor with PRP, among female patients, which explained 27% of total variance of the level of PRP.
Conclusion: Both of PFP and PRP of the stereotactic frame were moderate so that nurses should consider diverse strategies to reduce pain among patients undergoing gamma knife radiosurgery.
