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

• Status: Unknown status
• Trial end date: 2018-05-01
• Target enrollment: 0
• Participant gender: All

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.

Criteria

Inclusion Criteria:

• patients undergoing cardiac surgical procedures performed by a single conventional median sternotomy, and first case of the day patient because early postoperative pain scores are difficult to obtain overnight for patients admitted to the ICU in the evening.

Exclusion Criteria:
