In the article “Prophylactic Intrathecal Morphine and Prevention of Post-Dural Puncture Headache: A Randomized Double-blind Trial” published in the May 2020 issue, the terms intrathecal morphine and intrathecal saline are reversed in the Abstract and Results section.

The results section of the Abstract currently reads: “Epidural blood patch was administered to 10 of 27 (37%) of subjects in the intrathecal morphine and 11 of 21 (52%) of the intrathecal saline group (difference 15%; 95% CI, −18% to 48%).” The correct statement should read: “Epidural blood patch was administered to 11 of 21 (52%) of the intrathecal morphine group and 10 of 27 (37%) of subjects in the intrathecal saline and (difference 15%; 95% CI, −18% to 48%).” This statement is consistent with what is reported in Table 2.

The same error is found in the Results section. It currently reads: “Epidural blood patch was administered to 36% of subjects in the intrathecal morphine and 52% of the intrathecal saline group (difference, 16%; 95% CI, −17% to 49%).” The correct statement should be: “Epidural blood patch was administered to 52% of subjects in the intrathecal morphine and 37% of the intrathecal saline group (difference 15%; 95% CI, −18% to 48%).”

The authors regret the error. The online version and PDF of the article have been corrected.
