Brief summary:
Use of Muscle relaxant and reversal with Sugammadex at end of airway procedures will reduce the time to extubation after end of procedure

Detailed description:
This is a prospective, clinical interventional, randomized single blinded single center study.

Hypotheses:

Primary Hypothesis: Use of Muscle relaxant and reversal with Sugammadex at end of airway procedures will reduce the time to extubation after end of procedure

Secondary Hypotheses:

Surgeon will report optimal surgical conditions for ease of exposure

Have less hemodynamic changes in the OR and PACU. ∆ in BP, HR and CO2 from base-line and incidence /frequency of 20% change in BP from baseline vitals (baseline= pre-induction vitals)

Decrease the amount of inhaled anesthetics

Decreased narcotics needed intra-operatively and post operatively

Decrease the total OR time

Subjects will meet ALDRETE PACU discharge criteria quicker in the PACU

Subject will have less adverse events and severe adverse events such as - hypotension, arrhythmia, hypoxia, stridor and re-intubation.

We note that the nurses in PACU will be blinded to whether the subjects were in Group 1 or 2.

Group 1: Inhaled anesthetics: sevoflurane at 1 MAC, remifentanil and intubation with rocuronium at 0.6-1.2 mg/kg (vitals maintained within 20% of baseline). Group 1 will receive reversal with neostigmine (0.04 mg/kg and glycopyrrolate (0.01 mg/kg)

Group 2: Inhaled anesthetics: sevoflurane at 1 MAC, remifentanil and intubation with rocuronium at 0.6 -1.2 mg/kg (vitals maintained within 20% of baseline). Group 2 will receive reversal with sugammadex 4mg/kg

Both groups will receive standard anti-nausea prophylaxis - Ondansetran and Decadran intraoperative.

After induction, the amount of inhaled anesthetic and remifentanil used will be titrated based on hemodynamic parameters (maintained within 20% from baseline) and a BIS monitor.

All subjects will have TOF testing done every 5 minutes throughout the procedure and tabulated in the Electronic Medical Record (EMR).

At the end of the procedure patient will be extubated when the subject meets the following criteria:

Tidal volume : \> 5 cc /Kg Respiratory rate: \>8 /min O2sat \> 95% ON 100% inspired oxygen

With vitals at 20% of baseline. Extubation will begin when the surgeon states, "We are done". This usually coincides with the withdrawal of the scope. The start and end times for extubation will be recorded in the Electronic Medical Record.

The PACU nurses will evaluate ALDRETE discharge criteria and make a note in the electronic medical records for the subject discharge time from PACU. The nurses in PACU will be the only evaluators of the subject who will be blinded to the two groups

Section #2- Core Protocol 
 
2.1 Objectives & 
Hypotheses  
 
 
 
 
2.1 List the objectives.  
 
Outcome measures measured in the two groups: 
 
Primary outcome 
 
Time to extubation after end of procedure 
 West Virginia University Hospitals use an electronic medical record 
(EMR) to chart the end of the procedure.  When the surgeon states 
“We are done”, always at withdrawal of the scope, extubation 
begins.  From the time we chart end of procedure to the time of 
extubation is the extubation time.  The start and end times for 
extubation will be recorded in the EMR. 
 
The OR time is billed in 15 minute increments and it is a tremendous 
cost saving even for every 5 minutes saved.  It is anticipated that 
extubation using sugammadex will provide at least a 5 min reduction 
in extubation time when compared to the combination of 
neostigmine and glycopyrrolate (8, 11).  This translates to a possible 
45.8 % reduction (12, 13, 14).  
 
 
 Secondary outcomes 
 
1. Subjective interpretation of optimal surgical conditions as evaluated 
by the surgeon for ease of exposure graded from  1-10 ( 1 being 
difficult and 10 being the best  surgical conditions) 
2. Hemodynamic parameters – intra-op and post-op. ∆ in BP, HR and 
CO2  from base–line and incidence /frequency of 20% change in BP 
from baseline vitals ( baseline= pre-induction vitals) 
3. Respiratory parameters – intra op and post op 
4. Inhaled anesthetic concentration  intra-op 
5. Narcotics required intra op and post op  
6. Total OR time 
7. Time taken to meet ALDRETE criteria in PACU 
8. Time to discharge from PACU 
9. Any adverse event and severe adverse events such as - hypotension, 
arrhythmia, hypoxia, stridor and re-intubation will be compared in 
both groups

Sugammadex at end of airway procedures will reduce the time to 
extubation after end of procedure

➢ Have less hemodynamic changes in the OR and PACU. ∆ in BP, HR and 
CO2  from base–line and incidence /frequency of 20% change in BP 
from baseline vitals (baseline= pre-induction vitals) 
➢ Decrease the amount of inhaled anesthetics  
➢ Decreased narcotics needed intra-operatively and post operatively

as - hypotension, arrhythmia, hypoxia, stridor and re-intubation. 
 
2.2 Background & 
Rationale, 
Significance of 
Selected Topic & 
Preliminary Data  
 
Microlaryngoscopy and rigid bronchoscopy for vocal cord and tracheal 
procedures causes an intense sympathetic response during the procedure 
(1). Abrupt increases in heart rate, blood pressure can be seen in these 
procedures(1). Patients have to be extremely still for these highly stimulating 
procedures and hence have to be deeply anesthetized(2) (3). Ideal surgical 
exposure often depends on relaxation of muscles of mastication. Most of 
these procedures are done as outpatient procedures and many of these 
patients have significant co-morbidity. 
Deeply anesthetizing these patients can cause profound hypotension which 
can worsen the medical status of the patient and have longer PACU stay and 
can cause increased post-operative complications. 
Muscle relaxation with non-depolarizing muscle relaxants are rarely used in 
these procedures as the duration of action of the muscle relaxant is 
significantly longer than the actual procedure and time to extubation from 
end of procedure is significantly longer than without using muscle relaxation 
or a Succinylcholine drip.(4)  
Muscle relaxants are synergistic with inhaled anesthetics, and narcotics. 
Hence, the total amount of anesthetics and narcotics used can be 
significantly reduced when combined with muscle relaxants if we are able to 


       
fully reverse the paralysis at the end of the procedure.(5) 
 
2.3 Study Design 
 
 
This is a prospective, clinical interventional, randomized single blinded single 
center study.  We note that the nurses in PACU will be blinded to whether 
the subjects were in Group 1 or 2. 
 
After IRB approval, subjects will be consented in the clinic by the PI or CO-I 
for the study.  
 
After written consent is obtained and a copy provided to the subject; the 
following inclusion and exclusion criteria will be reviewed. The subject must 
meet all inclusion criteria and no exclusion criteria to qualify for the 
treatment phase. The subject that does not qualify will not be included in 
this study. 
Inclusion Criteria: 
➢ Age 18 years or older,  
➢ ASA physical status I-III 
➢ Ability to give written informed consent.  
 
Exclusion criteria: 
➢ Known or suspected neuromuscular disease/pre-existing weakness, 
➢ Creatinine clearance less than 30 ml/min,  
➢ Bradycardia of less than 40 beats/min, 
➢ Pregnancy, breast feeding women, 
➢ Known or suspected allergy to BRIDION® (sugammadex), neostigmine 
or rocuronium. 
➢ Patients with contraindications towards sugammadex, neostigmine 
or rocuronium 
➢ Patients included in another trial within the last 30 days 
➢ Patients with legal guardians or surrogate decision making 
➢ Patients who refuse to use non-hormonal contraceptive method or 
back-up method of contraception (such as condoms and spermicides) 
for the next 7 days if receiving sugammadex.  Ref (6)  
 
 
Patients will be randomized, using a block randomization scheme, to one of 
the two anesthetic groups.  The block randomization scheme will use 
random block sizes varying from 2 to 6 patients per block.  Subjects will 


       
receive a unique study id number (subject 1: i.e. 0001-{3 initial i.e. A-B-C}).  
The randomization scheme will be developed by the statistician; the master 
list of study ids and reversal treatment allocations will be held by the PI and 
research coordinator.  Strict adherence to the sequence of treatment 
allocations will be maintained. 
 
Group 1: Inhaled anesthetics: sevoflurane at 1 MAC, remifentanil and 
intubation with rocuronium at 0.6-1.2 mg/kg (vitals maintained within 20% 
of baseline).  Group 1 will receive reversal with neostigmine (0.04 mg/kg and 
glycopyrrolate (0.01 mg/kg)  
 
Group 2: Inhaled anesthetics: sevoflurane at 1 MAC, remifentanil and 
intubation with rocuronium at 0.6 -1.2 mg/kg (vitals maintained within 20% 
of baseline). Group 2 will receive reversal with sugammadex 4mg/kg  
 
Both groups will receive standard anti-nausea prophylaxis – Ondansetran 
and Decadran intraoperative. 
 
After induction, the amount of inhaled anesthetic and remifentanil used will 
be titrated based on hemodynamic parameters (maintained within 20% from 
baseline) and a BIS monitor.  
 
All subjects will have TOF testing done every 5 minutes throughout the 
procedure and tabulated in the Electronic Medical Record (EMR). 
 
At the end of the procedure patient will be extubated when the subject 
meets the following criteria: 
 
Tidal volume : > 5 cc /Kg 
Respiratory rate: >8 /min 
O2sat > 95% ON 100% inspired oxygen 
 
With vitals at 20% of baseline.  Extubation will begin when the surgeon 
states, “We are done”.  This usually coincides with the withdrawal of the 
scope.  The start and end times for extubation will be recorded in the 
Electronic Medical Record. 
 
 
The PACU nurses will evaluate ALDRETE discharge criteria and make a note 
in the electronic medical records for the subject discharge time from PACU. 
The nurses in PACU will be the only evaluators of the subject who will be 
blinded to the two groups 
 
 


       
Independent Data and Safety Committee Monitoring: 
Data and safety monitoring is a requirement of our institutional IRB (WVU 
IRB) and is standard for all clinical studies.  Independent Data and Safety 
Monitoring Committee: Individuals not involved with the study will review 
the data and make recommendations to continue or stop the study to the 
Principal Investigator.  
 
Following the WVU IRB Independent Data and Safety Monitoring Plan, a 
quality assurance audit will be performed by the IDSMC when 20% of the 
patients have been recruited (n=17).  This audit will include, but not be 
limited to, the review of informed consent process, eligibility confirmation, 
adherence to protocol procedures and treatment plans, pharmacy records 
and storage, and regulatory documentation. Adverse events and severe 
adverse events such as - hypotension, arrhythmia, hypoxia, stridor and re-
intubation will be compared in both groups. 
 
No analysis related to or involving the primary outcome is required or will 
be performed at this time.  
 
ADVERSE EVENT ASSESSMENT: any unfavorable and unintended medical 
occurrence, symptom or disease temporally associated with the use of a 
medical treatment of the subjects whether or not it is associated related to 
the medical treatment. The Principal Investigator will identify and make 
adverse events assessments. Adverse events and severe adverse events such 
as - hypotension, arrhythmia, hypoxia, stridor and re-intubation will be 
compared in both groups. 
 
 
SINGLE BLIND: The nurses in PACU will be the only evaluators of the subject 
who will be blinded to the two groups. The PACU nurses will evaluate 
ALDRETE discharge criteria and make a note in the electronic medical 
records for the subject discharge time from PACU.

2.6 Study Duration 
The estimate time for subject enrollment is 12 months, publication and 
presentation of data will follow completion of data analysis. 
 
2.7 Statistical 
Analysis and 
Sample Size 
Justification  
Power/Sample Size: 
 
All patients have a clearly defined time at which extubation begins and ends 
(See Section 2.3, Study Design).  There will be no patients with unobserved 
end points (e.g. no loss to follow-up, attrition, or right censoring).  
Additionally, the Data and Safety Monitoring does not require the analysis of 
the primary research question prior to the completion of the study (See 
Section 2.3, Study Design, Data and Safety Monitoring subsection).   
 
Based on these considerations, powering for the primary outcome of 
extubation time used the log-rank test, Schoenfeld’s method, and balanced 
allocation of patients to each group (9-10).  With minimum power of 80%, an 
alpha-level of 0.05, and an effect size of 0.542, a total of 84 patients are 
required providing 42 patients per group.   
 
The effect size was derived using median times-to-extubation to estimate 
the hazard ratio.  An estimate of the median extubation time for 
sugammadex is 6.4 minutes (8, 11) with a minimum differential of 5.4 
minutes for the combination of neostigmine and glycopyrrolate (i.e. 11.8 
min).  The 5.4 min differential is twice the differential between sugammadex 
and pyridostigmine (8), and is motivated by longer extubation times for 
neostigmine and glycopyrrolate when compared against pyridostigmine (15).  
The anticipated minimal differential has positive clinical and financial 
ramifications (Section 2.1 Objective & Hypotheses). 
 
 
 
 
 
 
Statistical Analysis: 
 


       
We will use univariate statistics (e.g. mean, median, standard deviation, 
interquartile range) to summarize the collected data.  Balance between the 
two groups for key patient variables (see Section 2.1 for examples) will be 
assessed using a two-sided two-sample t-test using unequal variances and 
the Welch modification to the degrees of freedom.  For categorical variables, 
the Chi-square test will be used.  If non-parametric tests or exact methods 
are required, we will use the Mann-Whitney U test and the Fisher-Freeman-
Halton exact test respectively. 
 
The primary comparison of extubation time between the two groups will be 
assessed using the Kaplan-Meier method and log-rank test.  Statistical 
significance will be assessed using a two-sided test with an alpha-level of 
0.05. All statistical analysis will be performed using the R software 
environment for statistical computing and graphics (7).

Introduction 
You,____________________, have been asked to participate in this research study, which has been explained 
to you by ______________________________________________.  This study is being conducted by Dr. 
Ranganathan Department of Anesthesiology at West Virginia University with funding support and Sugammadex 
(Bridion®) provided by Merck Investigator Studies Program. 
 
 
 
Purpose(s) of the Study 
The main purpose for this study is to collect data on the use of muscle relaxants and 2 types of Food And Drug 
Administration (FDA) approved reversal agents (1- Neostigmine, 2- Sugammadex) to see if Sugammadex will  
reduce the time to removal of breathing tube after the end of surgical procedures with micro laryngoscopy 
(examination of the airway, interior of the larynx with a laryngoscope with binocular magnification) as 
explained to you by your surgeon. 
 
Researchers will collect data on the time when the surgeons are done with the procedure to the time the 
breathing tube is removed from the  airway. The surgeons' reports as optimal surgical conditions for ease 
looking at  your airway, changes in vital signs if there is any from your baseline vital signs, amount of 
anesthetics used, total amount narcotics needed intra-operatively and post operatively, the total Operating 
Room time, PACU time and adverse events. 
 
WVU expects to enroll approximately 84 completed subjects. WVU is the only site. 
 
 
Description of Procedures 
This study involves collecting data on subjects that are going to have a procedure that require 
intubation and examination of airway and related airway structures. 
You are eligible to participate  in this study since you  are  going to  have  a  procedure to  look at  your throat,  
vocal cords and voice box structures. You are also eligible because you are 18 years of age or older and don't 
have an allergy to any of the medications that we may use as part of your anesthetic. 
Screening phase:  You  will discuss this consent with the  research staff  in the  clinic or surgery suite. You  may 
take a copy of this form home to read and make a decision prior to your procedure date. 
Participation is voluntary and if you decide to participate please inform the staff who will go through the 
consent process with you.

Treatment phase: Surgery 
 
You will have your surgery as your surgeon requires and you will be randomized (like flipping a coin) into 1 of 2 
groups: Both groups will receive standard of care treatments. The research team will collect data on the 
groups. You will be given a unique study ID number, i.e. 0001-ABC, to  help keep your identification confidential. 
The  principal  investigator and study coordinator will have access to the master code that links you to the 
research code. It will be on a computer 
and is password protected. 
 
 
Both groups will receive a standard general anesthetic. Both groups will receive all other standard 
medications given as part of a general anesthetic. 
 
Group 1 will receive reversal of paralysis with a medication called 
neostigmine. Group 2 will receive Reversal of paralysis with a medication 
called Sugammadex. 
Follow-up: 
 
Post anesthesia care unit (PACU): 
The nursing staff will document when you are ready for discharge from this area. These nurses will not know 
what group you are in. That information will be kept confidential and coded. 
You may receive a phone call within 30 days if you have had an adverse event such as low blood pressure, 
palpitations, shortness of breath, low oxygen levels after procedure, or needed to be re-intubated (replace tube  in 
throat  to  help you breath). If  you  have  not  had  an  adverse  event you will  be finished  with  the  study after 
discharge from the  post anesthesia care unit. 
Your participation may be terminated by the investigator  without  regard to  your consent at  any time if the  
investigator feels it is necessary. 
 
 
Risks and Discomforts 
Drugs often have side effects. The drugs used in this program may cause all, some, or none of the side effects 
listed. In addition, there  is always the  risk of  uncommon  or  previously  unknown  side effects.   There  may  be  
reasonably foreseeable invasive or non-invasive risks or discomforts due to your surgery. You will discuss and 
sign a surgery consent with your surgeon. 
 
Neostigmine Side effects 
Serious side effects may include: muscle weakness, slurred speech, vision problems, feeling like you 
might pass out, severe stomach cramps or diarrhea, trouble breathing, cough with mucus, fast or slow 
heart rate, convulsions,
