The PATHFINDER Study: A Feasibility Trial (PATHFINDER)

27. januar 2021 oppdatert av: Balachundhar Subramaniam, Beth Israel Deaconess Medical Center

Perioperative Multimodal General Anesthesia Focusing on Specific CNS Targets in Patients Undergoing Cardiac Surgeries

The main purpose of this study is to determine whether a rational strategy of EEG guided multimodal general anesthesia using target specific sedative and analgesics could result in enhanced recovery after anesthesia and surgery, decrease in postoperative delirium, and decrease in long term postoperative cognitive dysfunction up to 6 months following cardiac surgery.

Detaljert beskrivelse

The main purpose of this study is to determine whether a rational strategy of EEG guided multimodal general anesthesia using target specific sedative and analgesics could result in enhanced recovery after anesthesia and surgery, decrease in postoperative delirium, and decrease in long term postoperative cognitive dysfunction up to 6 months following cardiac surgery.

Specific Aim 1: The feasibility of implementing multimodal general anesthesia strategy in the Operating Rooms (OR) Specific Aim 2: The feasibility of implementing EEG guided sedation until extubation in the Intensive Care Unit (ICU) Specific Aim 3: The enhancement of recovery after surgery (shorter ventilation time, ICU stay, hospital length of stay) Specific Aim 4: To estimate the effect size of decrease in postoperative day (POD) and postoperative cognitive dysfunction (POCD) to power future large randomized trials

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Multimodal General Anesthesia

Intraoperative

The anesthesiologists involved in this study will be trained to infer differences in anti-nociception, unconsciousness movement and changes during other perioperative events by monitoring EEG. They will also be trained in titrating hypnotic and nociceptic medications based on changes in EEG.

  1. Routine anesthetic induction
  2. Bilateral Pectoro-interfascial block (PIFB) with 20 mL of 0.25% ropivacaine on either side of the sternum after anesthetic induction but before surgical incision
  3. Ketamine (0.06 to 0.12 mg.kg/hr)
  4. Remifentanil (0.05-0.2 mcg/kg/min)
  5. Dexmedetomidine (0.2-1.0 mcg/kg/hr)
  6. Rocuronium intermittent bolus (TOF)
  7. Propofol infusion ± Sevoflurane titrated based on EEG monitoring

Postoperative

  1. Standard pain management protocol
  2. Dexmedetomidine infusion 0.2-1.4 mcg/kg/hr (EEG guided)
  3. Infusion continued till extubation
  4. Propofol infusion may be added/used for sedation based on the treating physician's discretion

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Incidence of Delirium
Tidsramme: Participants will be followed for the duration of the hospital stay, an average of 5 days
Incidence of delirium will be analyzed in patients treated with the multi-modal approach. Delirium will be defined as an acute change in pre-operative baseline condition with additional features of inattention and either disorganized thinking and altered loss of consciousness, as defined by the Confusion Assessment Method (CAM)Assessment Method (CAM) algorithm postoperatively until discharge.
Participants will be followed for the duration of the hospital stay, an average of 5 days

Montreal Cognitive Assessment (MoCA)
Tidsramme: On the day of discharge, an average of 6 days
MoCA scores (total possible score is 30 points; a score of 26 or above is considered normal) at discharge will be reported in order to assess the occurrence of postoperative cognitive decline. Study staff trained in administering the assessments will collect the data.
