Sugammadex and Neostigmine at Shallow Neuromuscular Blockade (SUNDRO)

March 18, 2013 updated by: Technical University of Munich

Dose Finding Study for Sugammadex and Neostigmine at Residual Neuromuscular Blockade (T4/T1 = 0.5)

This study is designed to compare recovery times after reversal of a residual neuromuscular block (TOF-ratio 0.5) with different doses of either neostigmine or sugammadex.

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Muscle relaxants are integral part of modern anesthesia. They optimize intubating conditions, reduce laryngeal trauma and improve operating conditions. Drawback is a possible pharmacological (muscle relaxing) effect of these drugs beyond the end of the operation (i.e. post-operative residual curarization: PORC). Reportedly about 30% of all patients who received muscle relaxants show signs of PORC when arriving in the post-anesthesia care unit. PORC comprises the risk of impaired post-operative fine motor and coordinative skills with a possible impairment of swallowing pharyngeal secretions with an increased risk of aspiration after extubation. Possible deleterious effects of this could be pneumonia, bronchitis, myocardial infarction, cardiac insufficiency, stroke or re-operation.

In order to avoid PORC patients with residual neuromuscular block receive a muscle relaxant antagonist from the anesthetist at the end of the operation. However, these drugs (neostigmine, pyridostigmine, etc.) from the class of cholinesterase inhibitors have unwanted effects such as bradycardia, increased gastro-intestinal motility, post-operative nausea and vomiting, salivation etc. To decrease these unwanted side effects cholinesterase inhibitors have to be given in combination with parasympatholyics e.g. atropine or glycopyrrolate with their own spectrum of unwanted side effects.

From October 2008 on, Sugammadex, a completely new reversal drug was introduced in to clinical practice. Sugammadex, is a modified gamma-cyclodextrine able to specifically bind rocuronium (a steroidal muscle relaxant). The complex is eliminated via the kidneys. However, all studies so far have focussed on reversal of profound or deep neuromuscular blockade. This study is designed to compare recovery times after reversal of a residual neuromuscular block (TOF-ratio 0.5) with different doses of either the neostigmine or sugammadex.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 64 years (Adult)

Accepts Healthy Volunteers
