Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bupivacaine is the most widely used local anesthetic agent across majority of the Cardiac Implantable Electronic device (CIED) implant procedures in the United States. It is hypothesized that the combination of Bupivacaine-Ketorolac-Ketamine (BKK) is more effective in alleviating perioperative and postoperative pain as compared to the use of bupivacaine alone.

A few studies have been done to look for the effectiveness of BKK in abdominal surgical procedures. However, no study has been done to evaluate its efficacy and effectiveness in patients undergoing CIED insertion.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Bupivacaine is a widely used local anesthetic and is often administered by spinal injection prior to major surgical procedures. Ketorolac is a potent NSAID which is used for the short-term relief of moderate to severe pain. It's used for long term duration is generally limited due to its potential to cause GI ulcers/perforation and renal failure. A single dose of perioperative Ketorolac has been found to be effective in reducing opioid consumption. Ketamine is NMDA receptor antagonist and is used for its anesthetic, analgesic, and psychotomimetic effects. It is primarily used for induction and maintenance of anesthesia and induces a trance like state providing pain relief, sedation, and amnesia.

Although an effective local anesthetic agent, bupivacaine has weak analgesic effect and is used in combination with several analgesic agents for effective perioperative and postoperative analgesia. A common drug used in this analgesic regimen usually includes opioids such as morphine, oxycodone, and fentanyl. Over the last few decades the United States has witnessed an opioid epidemic and post-surgical opioid prescription is one of the major contributors of this epidemic. An opioid free combination of Bupivacaine-Ketorolac-Ketamine (BKK) is thought to be effective in alleviating perioperative and postoperative pain.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Bupivacaine Alone

This is the control group of patients receiving 20 cc of 0.5% bupivacaine (Bupivacaine HCL 100 mg \[5mg/ml\] alone. The dose and number of doses of the medicines will be adjusted as per discretion of the operator.

Group Type OTHER

Bupivacaine alone OR Bupivacaine-Ketorolac-Ketamine (BKK) Combination

Intervention Type DRUG

The plan will be to stratify patients in two groups: intervention group receiving 20 cc combination of BKK (Bupivacaine HCl 60 mg \[3 mg/mL\], Ketorolac Tromethamine 24 mg \[1.2mg/mL\], Ketamine HCl 24 mg \[1.2 mg/mL\]) vs the control group receiving 20 cc of 0.5% bupivacaine (Bupivacaine HCL 100 mg \[5mg/ml\]. The dose can be repeated multiple times during the procedure as per operator's discretion. The patients will be further stratified into sub-groups based on type of procedure they had undergone. Analgesia/anesthesia strategy will be local infiltration of the drug along with a sedating agent based on institutional standard of care. The dose of the medicines will be adjusted as per discretion of the operator to maintain adequate anesthesia/analgesia during and after the procedure.

Bupivacaine-Ketorolac-Ketamine (BKK) Combination

This is the intervention group of patients receiving 20 cc combination of BKK (Bupivacaine HCl 60 mg \[3 mg/mL\], Ketorolac Tromethamine 24 mg \[1.2mg/mL\], Ketamine HCl 24 mg \[1.2 mg/mL\]).The dose and number of doses of the medicines will be adjusted as per discretion of the operator.

Group Type EXPERIMENTAL
