MONITORING A NEUROMUSCULAR BLOCKADE STATUS

摘要

The present disclosure relates to various methods for determining a neuromuscular blockade status and systems suitable for performing such methods. The present disclosure further relates to electro-stimulation electrodes for stimulating a muscle of a patient, optionally in the context of at least some of the mentioned methods. The present disclosure still further relates to hybrid air-signal connectors for use in an electro-stimulation cuff which can be used in the context of at least some of the cited methods. The present disclosure also relates to electro-stimulation circuits comprising an electrode portion and a track portion suitable for pressure cuffs for electro-stimulation, and to pressure cuffs configured to be arranged around a limb of a patient and comprising an active electro-stimulation electrode and a passive electro-stimulation electrode. These electro-stimulation circuits and pressure cuffs may also be used in the context of at least some of the mentioned methods.

主权项

1. A method for automated determination of a neuromuscular blockade status for a patient to whom a muscle relaxant has been delivered, wherein
a plurality of neuromuscular blockade statuses are predefined, and for each of the neuromuscular blockade statuses there are predefined one or more stimulation cycles with a cycle periodicity and one or more criterions for changing from the neuromuscular blockade status to another neuromuscular blockade status, said one or more criterions including a first criterion or first set of criterions for changing the neuromuscular blockade status to a first other neuromuscular blockade status; the method comprising: automatically performing one or more stimulation cycles predefined for the neuromuscular blockade status; automatically determining one or more muscle responses to at least some of the performed stimulation cycles; automatically comparing the muscle responses with the one or more criterions for changing the neuromuscular blockade status; and if the muscle responses fulfil the predefined first criterion or first set of criterions, then automatically performing one or more stimulation cycles predefined for the first other neuromuscular blockade status.
