Abstract
Background: Spinal anesthesia is a kind of central neuraxial anesthesia and a better choice for
operations below the umbilicus. However most patients refuse it for future surgeries because of
post-spinal back pain.
Objective: To assess the Incidence, severity and associated factors of back pain after spinal
anesthesia in surgical patients at Addis Ababa governmental hospitals.
Methods: Multi-center prospective observational study was conducted in 404 patients operated
under spinal anesthesia at selected Addis Ababa governmental hospitals from February 1-April
30,2021. A systematic random sampling technique was used to select the patients. A structured
questionnaire was used to collect the data. Back pain after Spinal anesthesia was assessed using a
numeric pain rating scale. The data was analyzed with Statistical software version 24. The data
was described by texts, tables, and graphs. Binary logistic regression was used to see the
association between each independent variable with dependent variable. A P-value < 0.05 was
considered statistically significant.
Results: The overall incidence of back pain was 42.32%. The Mean severity of back pain in each
three post-operative days was mild to moderate. Body mass index, history of backache, spinal
needle size, number of attempts, and number bone contacts were associated with the incidence of
acute post-spinal backache.
Conclusion: The incidence of back pain was high at Addis Ababa governmental hospitals. To
minimize this, the anesthesia provider should use fine-gauge spinal needle, minimize multiple
attempts and multiple bone contacts.
