Brief Summary:
Comparing during anesthesia in the same patient 2 neuromuscular monitors on the same arm.

Condition or disease Intervention/treatment
Neuromuscular Blockade Diagnostic Test: measuring neuromuscular block

Detailed Description:

NMT (neuromuscular transmission) depth can be measured at the same arm with two different methods during clinical practice.

the first (TOF Watch) measures the musculus adductor pollicis acceleration while the second method (TOF Cuff Monitor) uses a blood pressure cuff to measure the pressure changes induced by the upper arm muscles.

During general anesthesia when NMB (neuromuscular block) is required both methods are used. Every 5 minutes, if clinical required, the NMB is monitored by TOF-PTC. If the measurement of TOF is zero the monitor continues by measuring PTC ( the system will measure TOF followed by PTC if TOF is zero) TOF-PTC is recorded and later compared for identity or systematic difference in one or the other direction.

The measured answer can be TOF 4 (4 answers) with a ratio between answer 1 and 4 expressed and a percentage, TOF 3 (3 answers), TOF 2, TOF 1, TOF 0 + PTC 20, TOF 0 + PTC 19, up to TOF 0 + PTC 0

Study Type : Observational
Estimated Enrollment : 20 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Observational Study Measuring Neuromuscular Block Depth by a TOF or PTC Monitor on the Thumb and on the Upper Arm of the Same Side.
Actual Study Start Date : March 1, 2018
Estimated Primary Completion Date : December 30, 2019
Estimated Study Completion Date : December 31, 2020

Intervention Details:
  • Diagnostic Test: measuring neuromuscular block
    During anesthesia patients are monitored with two instead of one NMT monitor. the difference in measured TOF-PTC is compared

Primary Outcome Measures :
  1. TOF-PTC value [ Time Frame: From induction of anesthesia (intubation with ETT) till end of anesthesia (extubation of ETT) most frequent between 1 and 2 hours, max 6 hours in duration ]
    Difference in TOF-PTC measured by two different devices during anesthesia.
