To the Editor:
I read with great interest the article by Hart and Owen (1) and commend the authors for their initiative to improve the safety of patients undergoing cesarean delivery under general anesthesia through introduction of an aviation-style checklist. However, I question whether inclusion in the checklist of the two items “Oxytocin” and “Nondepolarizing muscle relaxant” under the heading “Drugs drawn up” may present a potential risk, rather than improvement, for patient safety. Drug errors are among the most common threats to patient safety in anesthesiology (2,3), often involving muscle relaxants (3) as well as oxytocin in obstetric anesthesia (4). Neither oxytocin nor nondepolarizing muscle relaxants are mandatory components of the induction of anesthesia for cesarean section, and inadvertent administration of either drug may yield catastrophic outcomes. In a recent systematic review of strategies to minimize anesthetic drug errors, “removal of dangerous drugs from the operating theaters” was identified as one of four classified “strongly recommended” (5). On the basis of these findings, the items “Oxytocin” and “Nondepolarizing muscle relaxant” may perhaps be more safely included in a checklist under a separate heading such as “Drugs readily available.”
