Interest of the Automated Management of Deep Neuromuscular Blockade Monitoring : A Pilot Pre-post Quasi Experimental Study (CURATP)
Neuromuscular blockade (NMB) recommendations updated in 2018 by the Société Française d'Anesthésie et Réanimation (SFAR) recommend the use of NMB agents to facilitate surgical procedure during abdominal surgery by laparotomy or laparoscopy.
This study aims to evaluate deep NMB monitoring with automated management of NMB depth measurement (ATP mode) versus non-automated monitoring (PTC/TOF), in order to improve the maintenance of deep NMB during abdominal surgery.
The beneficial effects of deep NMB on the surgical conditions and thus the per and post operative surgical morbidity have been demonstrated in several studies, but the evidence are not yet consistent enough to make recommendations.
The monitoring of per operative NMB remains the rule, using the Train Of Four (TOF) at the ulnar nerve at the adductor of the thumb. However, when deep NMB for the most resistant muscles of the body is required (diaphragm and abdominal wall), the Post Tetanic Count (PTC) should be used.
In order to better adjust the NMB to the conditions of muscle relaxation required during surgery, an automatic mode called ATP for Automatic TOF/PTC has been developed (TofScan, Idmed, Marseille, France).
The investigators hypothesized that the use of the ATP would be able to better insure deep NMB, and to limit interventions on patients and/or on the NMB monitor during surgical procedure.
