Description of intervention(s) / exposure
Train of four count ratio (TOFR) and count (TOFC) measured on patients who arrive in Recovery Unit after general anaesthesia requiring muscle relaxant.
TOFR and TOFC will be measured using the GE Neuromuscular monitor (NMT).
TOFR will be performed in patients on arrival in Recovery by a scholarly selective medical student face to face with the patient. The initial TOFR will be measured. If it is less than 90% (0.9) then the TOFR will be measured at 1 minute intervals until the TOFR reaches 90%.

Outcomes
Primary outcome [1] 302892 0
Incidence of post-operative residual curarisation (PORC) in PACU after general anaesthesia requiring muscle relaxant.
Incidence of PORC will be assessed using the TOFR which will be measured with the GE NMT monitor.
Timepoint [1] 302892 0
Every minute from arrival in PACU until discharge from PACU
Secondary outcome [1] 337351 0
Prevalence of neuromuscular monitoring in the operating theatre complex of a tertiary hospital will be assessed by the review of the anaesthetic charts.
This review will be performed by the scholarly selective medical student.
Timepoint [1] 337351 0
From start of anaesthesia induction until patient is transferred to PACU
Secondary outcome [2] 337352 0
Incidence of adverse airway events in PACU
Oxygen saturation less than 92% as seen on pulse oximeter
Need for airway support such as jaw thrust or chin lift in PACU
Need for re-intubation in PACU
Timepoint [2] 337352 0
From arrival in PACU until patient is discharged from PACU
Secondary outcome [3] 338334 0
Time taken for TOFR to reach 0.9 in PACU was measured using the GE NMT monitor
Timepoint [3] 338334 0
Even minute from arrival in PACU until discharge from PACU

Summary
Brief summary
We aim to determine the incidence of post-operative residual curarisation (PORC) in Peri-anaesthesia care unit (PACU) after general anaesthesia requiring a muscle relaxant. We will also measure the incidence of adverse airway events in PACU and determine if there is an association with PORC.
As this was deemed to be a low risk study, patient consent was not required prior to recruitment. Patients were followed up in PACU after transfer from the operating theatre. Once in PACU, a neuromuscular monitor was placed and the train-of-four ratio (TOFR) was measured. This measurement was performed at 1 minute intervals until TOFR reached 0.9. The time then for TOFR to reach 0.9 was measured.
