Background: Accidental intrathecal vincristine (VCR) administration results in severe neurotoxicity, usually fatal in outcome. No specific therapy for initrathecal VCR toxicity has been reported so far. In our recent report, complete in vitro degradation of VCR by hypochlorous acid (HOCl) was demonstrated.
Methods: In this comparative study, we examined the in vivo effectiveness of HOCl in the cerebrospinal fluid of 24 New Zealand rabbits following intracisternal VCR administration.
Results: There were no significant clinical or histopathologic abnormalities in the control and HOCl groups; however, multiple necrotic foci on histopathological examination of brain sections in the VCR group were determined. There were significantly lower numbers of necrotic foci in brain sections of rabbits which received HOCl administration than those without therapy.
Conclusion: Our results indicate that HOCl may reduce VCR neurotoxicity.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Background: Post-dural puncture headache (PDPH) after an accidental dural puncture (ADP) is a common complication in obstetric analgesia. It has been proposed that inserting an intrathecal catheter (ITC) after an ADP may reduce PDPH incidence and the need for therapeutic epidural blood patch (EBP). Our primary objective was to assess if the insertion of an ITC after an ADP reduces the incidence of PDPH in obstetric patients.

Tranexamic acid (TXA) is increasingly used in the management of haemorrhage during and after delivery and haemorrhage caused by other medical conditions due to its efficacy and safety. However, increasing report of fatal complications from inadvertent intrathecal TXA injection remains a cause of concern. The aim of this case report is to demonstrate clinical presentation and predictors of accidental intrathecal injection of TXA within the structure and processes of care in a health facility.

Purpose Of Review: Medication administration errors represent a significant yet preventable cause of patient harm in the peripartum period. Implementation of best practices contained in this manuscript can significantly reduce medication errors and associated patient harm.
Recent Findings: Cases of medication errors involving unintended intrathecal administration of tranexamic acid highlight the need to improve medication safety in peripartum patients and obstetric anesthesia.
