A Comparison of Remifentanil and Dexmedetomidine for Craniotomy Perioperative Hemodynamics and Postoperative Pain (RemivsDex)

26 de octubre de 2016 actualizado por: The Cleveland Clinic
This will be a randomized blinded clinical trial. Patients will be randomized to receive either a remifentanil or dexmedetomidine infusion for general anesthesia. The anesthesia team will know the result of randomization at induction. Data will be gathered by research personnel who will be blinded to the anesthetic method used. Patients will be blinded to the anesthetic they receive till they are discharged from the PACU when they will have the option to be unblinded. The Data Safety and -Toxicity Committee will review all serious adverse events and toxicity reports as well as annual reviews.

Descripción detallada

Anesthesia for craniotomy presents a unique challenge to the anesthesiologist. Anesthesia for neurosurgical procedures should provide optimal surgical conditions while maintaining appropriate cerebral oxygen supply and stable systemic hemodynamics. (1) It is important to prevent patient response to noxious stimuli during the procedure like pinning, drilling of the bone, opening and manipulation of the dura etc., avoid coughing and bucking during surgery and during extubation thus necessitating a deeper level of anesthesia and analgesia. At the same time it is desirable to have the patient fully awake toward the end of the surgery in order to facilitate neurologic evaluation. Management of the above presents a challenge during induction, maintenance and extubation and also during multiple critical stages of surgery Fear of the side effects of analgesic drugs frequently leads to the under-treatment of post-craniotomy pain. (2) Nevertheless, this pain continues to be commonly observed, is frequently severe, and, if unrelieved, may cause distress for the neurosurgical patient and serious complications for the operative brain. (2) There is a need for larger trials to delineate safety and efficacy of analgesic therapies with a focus on short- and long-term outcomes.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Hemodynamics
Periodo de tiempo: 15, 30, 45, 60, and 90 minutes after extubation.
Hemodynamics were defined as mean arterial pressure (MAP), measured in milimeters of mercury (mmHg). This outcome was analyzed using a repeated measures ANOVA approach. In the outcome measure data table, mean ± standard deviation MAP was reported as the aggregate mean across time points.
15, 30, 45, 60, and 90 minutes after extubation.
Postoperative Pain
Periodo de tiempo: 15, 30, 45, 60, and 90 minutes after extubation.
Pain was measured using the visual analogue scale (VAS), where 0 is defined as no pain and 10 is defined as worst pain imaginable. This outcome was analyzed using a repeated measures ANOVA approach. In the outcome measure data table, mean ± standard deviation pain was reported as the aggregate mean across time points.
15, 30, 45, 60, and 90 minutes after extubation.
Total Opioid Consumption
Periodo de tiempo: Initial 90 minutes of recover after surgery
Total opioid consumption was defined as the sum of all opioid doses given within the first 90 minutes after surgery, converted to milligram morphine equivalents.
Initial 90 minutes of recover after surgery

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Heart Rate
Periodo de tiempo: 15, 30, 45, 60, and 90 minutes after extubation.
Heart rate was determined from the arterial catheter and measured as beats per minute. This outcome was analyzed using a repeated measures ANOVA approach.
15, 30, 45, 60, and 90 minutes after extubation.
Modified Short Orientation Memory Concentration Test (SOMCT)
Periodo de tiempo: 15, 30, 45, 60, and 90 minutes after extubation.
The Modified Short Orientation Memory Concentration Test (SOMCT) is a validated questionnaire that discriminates among mild, moderate, and severe cognitive deficits. SOMCT is based on 6 questions and produces a total score ranging from 0 (worst possible function) to 28 (best possible function). Scores > 20 are considered normal. This outcome was analyzed using a repeated measures ANOVA approach.
15, 30, 45, 60, and 90 minutes after extubation.
Aldrete Score
Periodo de tiempo: 15, 30, 45, 60, and 90 minutes after extubation.
The Aldrete score measured level of sedation and fitness and is used to assess the appropriate departure time from the post anesthesia care unit. The score ranges from 0 to 10, where 0 indicates poor fitness (and such patients are transferred to the ICU), while 10 indicates good fitness. This outcome was analyzed using a repeated measures ANOVA approach.
15, 30, 45, 60, and 90 minutes after extubation.
Nursing Workload Comparison
Periodo de tiempo: 90 minutes after extubation
To evaluate the nurses workload when either of the two drugs are given in terms Nursing Research Usage form's therapeutic index scoring system. This score ranges from 0 (minimal interventions and time spent by nurses on study patient) to 22 (maximum interventions and time spent by nurses on the study patient).
90 minutes after extubation
Drug Stop Time to Open Eyes
Periodo de tiempo: Anesthesia drug stop time to open eyes. Time is measured continuously until patients eyes open, regardless of how long it takes.
time until patient first opened their eyes, squeezed a hand, or wiggled their toes in response to verbal commands after surgery
Anesthesia drug stop time to open eyes. Time is measured continuously until patients eyes open, regardless of how long it takes.
Drug Stop Time to Recall
Periodo de tiempo: Time between extubation until patients could say their names.

Time between extubation until patients could say their names.
Drug Stop Time to Fitness to Discharge
Periodo de tiempo: Anesthesia drug stop time to fitness to discharge. Time is measured continuously until fitness for discharge is reached, regardless of how long it takes.
Anesthesia drug stop time to fitness to discharge. Time is measured continuously until fitness for discharge is reached, regardless of how long it takes.
End Case to Post Anesthesia Care Unit (PACU) Discharge
Periodo de tiempo: End case to post anesthesia care unit (PACU) discharge. Time is measured continuously until PACU discharge, regardless of how long it takes.
Post Anesthesia Care Unit (PACU) Discharge time is the timing at which patients are discharged from the PACU. This outcome is the amount of time (minutes) from end case to PACU discharge.
