Pain, Postoperative, Cardiac Surgery
Conditions
Brief summary
The primary objective of this study is to determine if the addition of PECS2 block provides superior post-operative analgesia for cardiac surgery patients after midline sternotomy compared to only standard-of-care post-operative pain medication.
Detailed description
The current study is a prospective, double-blind study investigating the use of pectoral nerves (PECS) block 2 to alleviate post-operative pain in cardiac surgery patients. The investigators anticipate enrolling a total of 220 participants in one of two groups, an interventional PECS block group and a control group not receiving the block. The intervention will occur in the operating room after the completion of the cardiac procedure and prior to the transfer of the participants to the cardiothoracic intensive care unit (CTICU). Both groups will receive the standard-of-care (SOC) pain regimen; the intervention with receive the PECS block in addition to SOC pain regimen. The procedure takes approximately five to ten minutes and will be conducted by the attending cardiac anesthesiologist. Pain will then be monitored hourly in the post-operative period in the CTICU. Additional measures will be investigated that are regularly logged in the electronic medical record.
Interventions
PROCEDUREPECS2 block
Superficial peripheral nerve block placed at the interfascial plane between the pectoralis major and minor muscles and the plane between the pectoralis minor and serrates anterior muscles. Targeted nerves include the lateral and medial pectoral nerves in addition to the long thoracic nerve, thoracodorsal, and thoracic intercostal nerves from T2 to T6.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Score on Critical-Care Pain Assessment Tool (CPOT) | 24 hours | Measured at least hourly prior to extubation. This is an 8-item pain inventory seen as one of the top modalities for measuring pain in critical care patients. Minimum score of 0 and a maximum score of 8 (higher score = higher pain level). |
| Score on Visual Analog Scale (VAS) | 24 hours | Measured at least hourly after extubation. 10 point pain analog scale (0-10, where 0 is no pain and 10 is highest pain level) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of operating room time | 5-7 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is a time scale with the time of 0 corresponding to the into operating room time and the final time being the out of operating room time |
| Total intraoperative fentanyl dose | Intraoperative duration | Documented by anesthesia physician as standard of care - will be retrieved in the EMR. The scale is an absolute dosing scale in grams. It will be corrected for by weight (kilograms). |
| Duration of ICU stay | 24-48 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is time. Time zero is out of operating time and end time is time of downgrade or discharge from the hospital. |
| Duration of hospital stay | 5-7 days post-operative | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is a time with time zero corresponding to admission to hospital time and end time being the time of discharge from the hospital. |
| Time to first opiate dose for breakthrough pain | 24-48 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is time. Time zero will be out of operating room time and end time will be time of administration of first opiate pain medication. |
| Ventilatory duration post-operatively | 0-6 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is a time scale with the time of 0 corresponding to the out of operating room time and the final time being the time period from the 0 time to the time when the patient is extubated. |
| Number of episodes of post-operative breakthrough pain | 24-48 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is an absolute number documenting the number of documented episodes of breakthrough pain. |
| Total post-operative opiate dose | 5-7 days post-operative | Documented by registered nurse as standard of care - will be retrieved in the EMR. The scale is an absolute dosing scale in grams. It will be corrected for by weight (kilograms). |
| Score on Critical-Care Pain Assessment Tool (CPOT) at 24-48h | 24-48 hours | This is an 8-item pain inventory seen as one of the top modalities for measuring pain in critical care patients. Minimum score of 0 and a maximum score of 8 (higher score = higher pain level). Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR |
| Score on Visual Analog Scale (VAS) at 24-48h | 24-48 hours | 10 point pain analog scale (0-10, where 0 is no pain and 10 is highest pain level) Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR |
| Number of adverse events related to safety of the nerve block | 5-7 days post-operative | Adverse events including but not limited to hemodynamic instability, respiratory depression, allergic reaction, shivering. |
| Time to first analgesic post-operatively | 24-48 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR. The scale is time. Time zero will be out of operating room time and end time will be time of administration of first breakthrough pain medication. |
| Duration of surgery | 4-6 hours | Documented by nursing, physician assistants, physician, and/or respiratory staff as standard of care - will be retrieved in the EMR (Electronic Medical Records). The scale is a time scale with the time of 0 corresponding to the first incision time and the final time being the time period from the 0 time to the time when the PECS2 block is completed. |
