Analgesic Effects of Transversus Thoracic Plane (TTP) Block in Cardiac

Status Not yet recruiting

Clinical Trial Summary

The TTP block is a novel regional anesthetic technique that shows promise in providing analgesia for anterior chest wall incisions and median sternotomy. The investigators hope to show that by providing the TTP block, there will be reduced early postoperative pain, reduced sedation and shallow breathing, reduced time on breathing machine, leading to an increase in patient comfort and satisfaction. The investigators also hope the decreased need for pain medication and reduced time on the breathing machine will translate into decreased nursing workload.

Clinical Trial Description

In February 2015, Ueshima et al published an article regarding ultrasound guided transversus thoracic muscle plane (TTP) block for breast cancer resection. In this article, he showed that branches of the intercostal nerves (Th2-6) dominate the region of the internal mammary area. By administering local anesthetics between the internal intercostal and transversus thoracic muscle, analgesia in the anterior chest and sternum can be obtained. A cadaveric study shows injectate spread from the second to fifth intercostal spaces with a single 15mL injection between the third and fourth ribs next to the sternum. They further published a case series of two patients who successfully underwent median sternotomy for aortic valve replacement and thymoma resection using only the TTP block for analgesia. Fast- track cardiac surgery is now widely practiced, and evidence for its safety and efficacy has spurred its adoption. With the increased demand for health care resources including nursing manpower and ICU beds, postoperative patients are returning to the cardiac surgery intensive care unit (CSICU) on shorter acting anesthetic agents so that they can be awakened, following commands and spontaneously ventilating earlier. The TTP block fits in well with the fast- track paradigm. By providing adequate analgesia for median sternotomy, the TTP block may reduce narcotic requirements and consequent sedation and respiratory depression, hypercapnia and respiratory acidosis, prolonged mechanical ventilation and need for emergency advanced airway interventions. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
