Aim: To explore * the frequency of use of objective neuromuscular monitoring for assessment of depth of neuromuscular blockade in general anaesthesia * the incidence of residual neuromuscular blockade, and * the timing of reversal of the neuromuscular blockade at the end of anaesthesia. We will collect data from 7 Danish anaesthesia departments, using data from the Anaesthesia Information Management System (AIMS).

Herlev Hospital
Herlev, Denmark
Number of Participants With and Without Objective Neuromuscular Monitoring (Acceleromyography) in Cases Receiving a Non-depolarizing Neuromuscular Blocking Agent (NMBA) (Yes/no)
Time frame: in the period from induction of anaesthesia to termination of anaesthesia, usually 2 hours
Number of Participants With and Without Objective Neuromuscular Monitoring (Acceleromyography) in Cases Receiving a Depolarizing NMBA (Succinylcholine) (Yes/no)
Time frame: in the period from induction of anaesthesia to termination of anaesthesia, usually 2 hours
Last Recorded Train-of-four (TOF) Ratio Before Tracheal Extubation or Removal of Supraglottic Airway Device in Patients Receiving a Non-depolarizing NMBA
The train-of-four (TOF) ratio is the ratio between the last and first measurements after four stimuli of the ulnar nerve at 2 Hz. The ratio should be at least 0.9 before tracheal extubation.
Time frame: in the period from induction of anaesthesia to termination of anaesthesia, usually 2 hours
Number of Participants With and Without Administration of Sugammadex in Cases Receiving a Non-depolarizing NMBA (Yes/no)
Time frame: in the period from induction of anaesthesia to discharge from the post-anaesthesia care unit, usually 5 hours
Number of Participants With and Without Administration of Neostigmine in Cases Receiving a Non-depolarizing NMBA (Yes/no)
Time frame: in the period from induction of anaesthesia to discharge from the post-anaesthesia care unit, usually 5 hours
Time in Minutes From Tracheal Extubation or Removal of Supraglottic Airway Device to Discharge From Post-anaesthesia Care Unit in Cases Involving a Non-depolarizing NMBA With and Without Neuromuscular Monitoring, Respectively
Time frame: in the period from induction of anaesthesia to discharge from the post-anaesthesia care unit, usually 180 minutes
