简要总结

The goal of this clinical trial is to assess how the location of local anesthetic medication affects pain control capabilities in adult patients undergoing thoracic(chest)-only minimally invasive surgery. The main questions it aims to answer are:

  • Is pain decreased when local analgesia is provided as a combination of serratus anterior plane block and intercostal nerve block when compared to either block administered individually?
  • How does location of local analgesia administration impact length-of-stay, cost-of-care, and quality-of-life?

Researchers will compare three treatment options including long-acting local anesthetic (Exparel®) administered as (1) intercostal nerve block, (2) serratus anterior plane block, or (3) combination of intercostal nerve block and serratus anterior plane block to see if pain and opioid use are reduced dependent upon treatment group.

All participants will receive a local anesthetic nerve block. Participants will be asked to describe their pain after surgery and to answer various questionnaires before and after surgery.

Arm 1 "LipoB-I": Liposomal Bupivacaine via Multi-Level Intercostal Nerve Block

Experimental

Patients randomized to Arm 1 "LipoB-I" will receive Liposomal Bupivacaine (LipoB) as an intra-operative multi-level intercostal nerve block containing 266mg (20mL) of Liposomal Bupivacaine (Exparel®) combined with 50mg (20mL) of 0.25% Bupivacaine Hydrochloride, for a total of 40mL for the block.

Arm 2 "LipoB-S": Liposomal Bupivacaine via Serratus Anterior Plane Block

Experimental

Patients randomized to Arm 2 "LipoB-S" will receive Liposomal Bupivacaine (LipoB) as an intra-operative serratus anterior plane block containing 266mg (20mL) of Liposomal Bupivacaine (Exparel®) combined with 50mg (20mL) of 0.25% Bupivacaine Hydrochloride, for a total of 40mL for the block.

Arm 3 "LipoB-C": Liposomal Bupivacaine via Combination Block

Experimental

Patients randomized to Arm 3 "LipoB-C" will receive Liposomal Bupivacaine (LipoB) as an intra-operative combination block (multi-level intercostal nerve block [ICNB] and serratus anterior plane block [SAPB]) with half the dose of Liposomal Bupivacaine administered in each block. Block solutions are as follows:

10mL LipoB mixed with 10mL 0.25% Bupivacaine Hydrochloride and 20mL of saline, administered as SAPB by anesthesiologist immediately prior to incision while in the operating room

AND

10mL LipoB mixed with 10mL 0.25% Bupivacaine Hydrochloride and 20mL of saline administered as ICNB prior to closure in at least 5 intercostal spaces as determined by administering surgeon while in the operating room.

结局指标

主要结局

NRS AUC 72

时间窗: Post-operative day 0 to post-operative day 3 (if still present in the hospital)

The investigators will obtain the NRS NRS AUC 72 (units: NRS·hours) (units 0-10) from time 0, entry into the recovery room, to 72 hours after entry into the recovery room. Pain will be assessed by the nursing staff, typically every 4 hours, and by research staff at least once on post-operative days 1-3. The times t0,t1,…,tk in hours within the range of 0 to 72 hours will correspond to NRS scores y0,y1,…,yk. Using the trapezoidal rule over the observed interval (assuming irregular and irregular timing), where: AUC=∑i((yi+yi+1)/2)(ti+1-ti), the maximum NRS·hours would be 10 x 72 hours + 720. If an individual patient measurement is taken off-schedule, the actual time stamps will be utilized. The trapezoidal rule naturally accommodates irregular spacing. If a patient is discharged early, or there is missing data, the AUC will be computed over the observed intervals and reported as time-standardized AUC = (AUC over observed time)/observed hours x 72.

Numeric Rating Scale (NRS)

时间窗: Post-operative day 0 to post-operative day 3 (if still present in the hospital)

A pain numeric rating scale will be administered to all patients in the trial from post-operative day 0 to post-operative day 3 in the hospital. Study personnel will gather a NRS value once a day for post-operative day 1-3 and nursing staff will gather a NRS value multiple times a day, typically every 4 hours, per their protocol. Average and maximum values (Likert scale 0-10) will be recorded each day.

次要结局

  • Quality-of-Life (Measured by Quality of Recovery Scale)(Post-operative day 1 to post-operative day 3 (if still present in the hospital), as well as at clinic follow-up at 2-5 weeks and via telephone at 90, 180, and 365 days post-operatively)
  • Pain Interference via PROMIS Pain Interference (PROMIS-PI)(Clinic follow-up at 2-5 weeks and via telephone at 90, 180, and 365 days post-operatively)
  • Quality of Sleep via PROMIS Sleep Disturbance Short Form (SF)(Post-operative day 1, as well as at clinic follow-up at 2-5 weeks and via telephone at 90, 180, and 365 days post-operatively)
  • Opioid Usage(Post-operative day 0 up to 14 days post-operation)
  • Cognitive Function via Neurologic Electrical Response(During surgery (intra-operative EEG) with follow-up assessments (minimal mental state exams) post-operatively up to 14 days post-operation.)
  • Respiratory Function via Incentive Spirometry(Post-operative day 0 up to 14 days post-operation)
  • Adverse Events(Post-operative day 0 to clinic follow-up at 2-5 weeks post-operatively)
