Residual Block in Postoperative Anaesthetic Care Unit

NCT02930629 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 400

Last updated 2017-05-01

No results posted yet for this study

Summary

The purpose of this study is to assess the incidence of residual block in patients arriving in the Post Anaesthetic Care Unit (PACU) following surgery, and in those who have received neuromuscular blocking drugs (muscle relaxants). Residual block (decreased motor function) due to residual levels of muscle relaxants is associated with increased morbidity.

Conditions

  • Neuromuscular Blockade

Interventions

DEVICE

Train-of-Four (TOF) Watch

For patients, on arriving in PACU after having had muscle relaxants during general anaesthesia * Two ECG electrodes will be placed 4 cm apart over the path of the ulnar nerve of the wrist after cleaning the skin with alcohol swabs. * The TOF force transducer will be placed on the volar aspect of the thumb. * The TOF Watch leads will be attached to the ECG electrodes. * A TOF stimulus will be applied: four twitches at 2Hz (every 0.5 seconds), each twitch lasting 0.2ms, and at a current of 50 mA. As far as possible, this will be done when patients are still slightly drowsy from the effects of anaesthesia. * Two TOF ratio will be elicited (two sets of four twitches 15 seconds apart), and an average of the two taken
