Lidocaine spray effective in pain management related to radial arterial puncture: Study

Results of the study are:

The research was performed with 67 patients (34 patients in the lidocaine group, 33 patients in the placebo group) who were admitted to the emergency department and required ABG analysis. Forty-three patients were men, and 24 were women. The ages of the patients ranged between 19 and 86 years, and the mean (± standard deviation) age was 56.3 ± 16.6 years. Pain levels, as measured by VAS, were significantly lower in the lidocaine group (24.00 mm IQR:[14.75–33.75]) compared with the placebo group (33.00 mm IQR:[22.00–61.50]) during radial arterial puncture (p = 0.011).

Thus, the researchers concluded that the level of pain perceived during radial arterial puncture was significantly lower in those who were administered lidocaine spray.
