About this study

Official title: Observational Project on the Current Neuromuscular Monitoring Practice (Including Extubation Practice) Via TOF-ratio (Train-of-four) Measurements in Different Types of Surgery After Administration of Neuromuscular Blocking Agents With or Without Reversal (Protocol No. P06556)

The intent of this observational study is to collect prospective data regarding neuromuscular monitoring practices and extubation standards (Train-Of-Four [TOF] value) during surgery, in countries of Central and Eastern Europe, Middle East and Africa (CEE/EEMEA countries). Secondarily the study will observe, for which surgical procedures neuromuscular blocking agents (NMBAs), and reversal agents to such, are used. This study is a non-interventional clinical trial, and administration of NMBAs, and respective reversal agents, (as well as all drugs used during anesthesia) will be done in accordance with routine anesthesiology practice, and labeling guidelines. Neuromuscular transmission will be monitored according to routine anesthesiology practice by means of acceleromyography. The assignment of the participant to a particular therapeutic strategy is not decided in advance by a trial protocol, but falls within current practice and the prescription of the medicine is clearly separated from the decision to include the patient in the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • No neuromuscular blockade (NMB)-reversal agent usedOther

    Participants whose reversal from NMB is spontaneous (no reversal agent used)

  • SugammadexDrug

    Also called Bridion, SCH 900616

    Participants receive NMB-reversal agents at the discretion of the treating physician per label according to local guidelines, in accordance with routine anesthesiology practice.

    As this is a prospective observational study designed to collect data as part of routine clinical practice, the protocol does not assign which reversal agents, if any, are to be used. This intervention is associated with a cohort that is intended to include participants who receive the NMB-reversal agent sugammadex, administered according to the local clinical practice and drug product labeling.

  • Other NMB-Reversal Agents Used in Routine Anesthesiology PracticeDrug

    Participants receive NMB-reversal agents at the discretion of the treating physician per label according to local guidelines, in accordance with routine anesthesiology practice.

    As this is a prospective observational study designed to collect data as part of routine clinical practice, the protocol does not assign which reversal agents, if any, are to be used. This intervention is associated with a cohort that is intended to include participants who receive any NMB-reversal agent other than sugammadex, and represents multiple drugs whose use and administration may vary according to local clinical practice, product availability and product labeling.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With a Train-Of-Four (TOF)-Ratio <0.9 at Extubation

    Neuromuscular function assessment was performed according to routine anesthesiology practice. This typically involves application of repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve and assessment of twitch response at the adductor pollicis muscle. The TOF-ratio, expressed as a decimal from 0.0 up to 1.0, is the ratio of the magnitude of the fourth twitch (T4) to that of the first twitch (T1). The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade. The TOF-ratio was measured at the time of post-surgical extubation. TOF-ratio at time of extubation was to be recorded for each participant, if available, irrespective of the criteria used to make the decision to extubate the participant. TOF-ratio <0.9 at extubation is considered to indicate a high risk for development of postoperative residual curarization (i.e, residual neuromuscular blockade), which can result in respiratory complications.

    Measured: At extubation (approximately <1 to 125 minutes after end of surgery)

  2. Time From End of Surgery (End of Last Stitch) to Extubation

    This measure is the duration from the last surgical wound stitch to the post-surgical extubation of the participant. The time of extubation was to be recorded for each participant, irrespective of the criteria used to make the decision to extubate the participant. Data are presented by TOF-ratio <0.9 and ≥0.9 at extubation. The TOF-ratio is a measure of neuromuscular function ranging from 0.0 to 1.0. The greater the T4/T1 ratio the greater

    the recovery from neuromuscular blockade. TOF-ratio <0.9 at extubation is considered to indicate a high risk for development of postoperative residual curarization (i.e, residual neuromuscular blockade), which can result in respiratory complications.

    Measured: From end of surgery (end of last stitch) to extubation (duration of approximately <1 to 62 minutes)

  3. Type of Surgical Procedure Performed in Study Participants

    The type of surgical procedure performed in each study participant was recorded.

    Measured: Day of surgery (Day 1)

  4. Type of NMB-reversal Agent Administered to Study Participants

    For all participants who received an NMB-reversal agent, the specific agent administered was recorded.

    Measured: At administration of NMB-reversal agent (up to approximately 395 minutes after start of surgery)

Secondary outcomes (2)
  1. Time From NMB-reversal Agent Administration to Operating Room Dismissal

    This measure is the duration from NMB-reversal agent administration to dismissal of the participant from the Operating Room. The time of dismissal from the Operating Room was to be recorded for each participant, irrespective of the criteria used to make the decision to dismiss the participant.

    Measured: Post-surgical period (up to approximately 24 hours post-surgery)

  2. Time From NMB-reversal Agent Administration to Recovery Room Dismissal

    This measure is the duration from NMB-reversal agent administration to dismissal of the participant from the Recovery Room. The time of dismissal from the Recovery Room was to be recorded for each participant, irrespective of the criteria used to make the decision to dismiss the participant.

    Measured: Post-surgical and recovery period (up to approximately 170 hours post-surgery)

What does the primary outcome measure?

Number of Participants With a Train-Of-Four (TOF)-Ratio <0.9 at Extubation (time frame: At extubation (approximately <1 to 125 minutes after end of surgery)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Mar 2015.
