Background: Pectoral nerve (PECS1) block has been used for patients undergoing cardiac implantable electronic device (CIED) insertions, however, PECS1 block alone may lead to inadequate analgesia during tunneling and pocket creation because of the highly innervated chest wall. Transversus thoracis muscle plane (TTM) block targeting the anterior branches of T2-T6 intercostal nerves can be effectively used in combination with PECS1 for patients undergoing CIED insertion. The present study hypothesized that combined PECS1 and TTM blocks would provide effective analgesia for patients undergoing CIED insertion compared to PECS1 block alone. Materials and Methods: Thirty adult patients between the age group of 18–85 years undergoing CIED insertion were enrolled in the study. A prospective, randomized, comparative, pilot study was conducted. A total of 30 patients were enrolled, who were randomized to either Group P: PECS1 block (n = 15) or Group PT: PECS1 and TTM blocks (n = 15). The intraoperative requirement of midazolam and local anesthetic and level of sedation by Ramsay sedation score were noted. The pain was assessed by visual analog scale (VAS) at rest and during a cough or deep breathing at 0 h, 3 h, 6 h, 12 h, and 24 h after the procedure. Results: VAS scores at rest were significantly lower in group PT at 0, 3, 6, and 12 h postprocedure, and during cough at 0, 6, and 12 h after the procedure (P < 0.05). At 24 h, VAS scores were comparable between both groups. Intraoperative midazolam consumption was higher in group P compared to group PT (P= 0.002). Fourteen patients in group P received local anesthetic supplementation in comparison to only one patient in group PT (P = 0.0001). Thirteen patients in group P received the first rescue analgesia in comparison to three patients in group PT (P = 0.0003). Conclusion: Combined PECS1 and TTM blocks provide superior analgesia, reduced net consumption of local anesthetic, sedative agents, and rescue analgesics compared to PECS1 block alone in patients undergoing CIED insertion.
