Educational intervention with serial album about pregnant women positioning for spinal anesthesia: randomized clinical trial.

OBJECTIVE To evaluate effectiveness of using educational intervention serial album to positioning pregnant women for spinal anesthesia. METHOD Randomized clinical trial with 90 women casually assigned to control (CG) and intervention group (IG), in a maternity hospital located in Northeast region of Brazil. The primary endpoint was "achieve correct positioning to perform spinal anesthesia"; and secondary, "how number of spinal cord puncture attempts". Effectiveness was verified using the chi-square test, Fisher's exact test and likelihood ratio. RESULTS The positioning was correct in 37 women in each group. There was an association between women in control group remaining still, relaxing shoulders and flexing the spine; and women in intervention group should remain still and relax the shoulders; furthermore there was a statistical association achieved by correct positioning and the number of attempts to access the lumbar puncture. CONCLUSION Educational intervention with serial album was effective and contributed to immobility and positioning of pregnant women. Brazilian Registry of Clinical Trials (RBR-3Z7SRD).
