RESUMEN
Objective:To study the effects of cold spray on pain after non-coring needle insertion.Methods:This was a randomized controlled study. Patients with totally implantable access port (TIAP) were randomly divided into the experimental group and the control group. The experimental group were given cold spray, while the control group were given eutectic mixture of local anesthetics cream (EMLA). The severity of pain, comfort and satisfaction, right-first-time insertion rate and skin reaction incidence were compared between groups.Results:29 patients were included in each of the two groups. The pain assessed with numeric rating scale in the experimental group was less severe than the control group ([1.52±1.02] vs [2.24±1.62]). However, there was no significant difference (d=-0.02 [95% CI:-0.55~0.51], P=0.109). The right-first-time insertion rate was 100% for both groups. The incidence of skin reactions in experimental group was lower (ARR=27.6% [95% CI: 11.32%~43.86%], P=0.008), and comfort scores ( d=-0.97 [95% CI: -0.42~-1.52], P<0.01) and satisfaction scores(ARR=13.8% [95% CI: 1.24%~26.34%], P=0.013) were significantly higher compared with control group. Conclusions:There was no statistically significant difference in the analgesic effect of cold spray and EMLA on pain from non-coring needle insertion. Cold spray acted quickly, comfortably and safely, resulting in better patient satisfaction.
