Clinical Trial Summary

This study will assess the residual neuromuscular blockade (NMB) Train-Of-Four (TOF) ratios at tracheal extubation when anesthesiologists have determined that full recovery of neuromuscular function has occurred using standard clinical criteria for participants whose non-depolarizing-induced NMB is either not reversed or reversed with an acetylcholinesterase inhibitor administered as per standard routine care.


Description:

This is a prospective, multi-site, anesthesiologist and PACU nurse TOF-Watch SX® blinded observational study of surgical patients undergoing elective laparoscopic or open abdominal procedures requiring general anesthesia and non-depolarizing neuromuscular blockade. There are two temporal aspects to the data collection: a prospective data collection in the OR and PACU; and a retrospective chart review one week after hospital discharge.

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With Residual Neuromuscular Blockade (NMB)(Train of Four [TOF] Ratio <0.9) at Time of Tracheal Extubation Neuromuscular functioning was monitored at time of tracheal extubation by applying three TOF electrical stimulations to the ulnar nerve and assessing twitch response at the adductor pollices muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from NMB, with a higher ratio indicating greater recovery from NMB. A T4/T1 Ratio of <0.9 is indicative of residual NMB. Immediately prior to tracheal extubation in the OR No
Secondary Percentage of Participants With Residual NMB (TOF Ratio <0.9) Upon Arrival to the Post-anesthesia Care Unit (PACU) Neuromuscular functioning was monitored at time of PACU arrival by applying three TOF electrical stimulations to the ulnar nerve and assessing twitch response at the adductor pollices muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from NMB, with a higher ratio indicating greater recovery from NMB. A T4/T1 Ratio of <0.9 is indicative of residual NMB. Immediately upon PACU arrival No
Secondary Percentage of Participants With Residual NMB at Various TOF Ratios (<0.6, =0.6 to <0.7, =0.7 to <0.8, =0.8 to <0.9) at Tracheal Extubation Neuromuscular functioning was monitored at time of tracheal extubation by applying three TOF electrical stimulations to the ulnar nerve and assessing twitch response at the adductor pollices muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from NMB, with a higher ratio indicating greater recovery from NMB Immediately prior to tracheal extubation in the OR No
Secondary Percentage of Participants With Residual NMB at Various TOF Ratios (<0.6, = 0.6 to <0.7, = 0.7 to <0.8, =0.8 to <0.9) Upon Arrival to the PACU Neuromuscular functioning was monitored at time of PACU arrival by applying three TOF electrical stimulations to the ulnar nerve and assessing twitch response at the adductor pollices muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from NMB, with a higher ratio indicating greater recovery from NMB. Immediately upon PACU Arrival No
