Text: Compared with no treatment, pain scores were lower in the morphine and tetracaine-morphine groups during skin preparation (mean difference, -0. 22 ; 95 % confidence interval [CI], -0. 4 to -0. 04 ; P =. 02 and -0. 29 ; 95 % CI, -0. 49 to -0. 09 ; P =. 01, respectively), and needle puncture (mean difference, -0. 35 ; 95 % CI, -0. 57 to -0. 13 ; P =. 003 and -0. 47 ; 95 % CI, -0. 71 to -0. 24 ; P <. 001, respectively), but pain scores did not differ statistically for tetracaine alone vs no treatment.
