Patients with intractable spasticity treated with intrathecal baclofen (ITB) need regular evaluation and aftercare in an outpatient clinic or pain clinic setting. Logistically, this can be challenging. A solution could be to perform treatment at the patient's home setting. In the Netherlands, a project of the Dutch Healthcare Authority was initiated to deliver ambulatory ITB-related services via a home-based Ambulant Care Clinic. This aftercare is performed by nurse practitioners (NP) with support from a medical specialist. The scope of the study was to investigate the efficiency and safety of ITB-care for patients with severe disabling spasticity in their home setting. ⋯ The concept of ITB aftercare on location demonstrated efficacy and safety in the described setting. For troubleshooting, close collaboration with a neuromodulation center is necessary and can be arranged in chain-based care.

We determined whether intrathecally delivering the same daily dose of morphine (MS) at a fixed concentration of 25 mg/mL by periodic boluses versus continuous infusion would reduce intrathecal mass (IMs) formation in dogs. ⋯ Using multiple bolus dosing, IMs were reduced as compared to continuous infusion, suggesting relevance of bolus delivery in yielding reduced intrathecal masses.

The approach to intrathecal (IT) drug delivery malfunction is complicated, particularly for iodine-allergic patients. In these situations, the current literature has not addressed the use of IT gadolinium. Case reports exist showing severe neurotoxic manifestations with IT gadolinium use. We sought to provide a resource for chronic pain physicians treating an iodine-allergic patient and considering the use of IT gadolinium. ⋯ Herein, we provide guidance on IT gadolinium usage and a framework for IT pump malfunction in iodine allergic patients.

Structural differences of implantable drug delivery systems (IDDSs) might have an impact on the efficiency of needle access to the reservoir fill port (RFP). The aim of this study was to assess the efficiency of RFP needle access with an ultrasound (US)-guided vs. a blind refill technique in IDDSs with a Recessed RFP (Recessed-RFP-IDDS). ⋯ The results of this study suggest that there is no difference in the RFP needle access efficiency between the US-guided and the blind refill technique in superficially located Recessed-RFP-IDDSs, if performed by experienced practitioners. However, the study did not address efficiency of the RFP needle access in IDDSs with aberrancy in pump location or refills performed by inexperienced staff.
