Transverse thoracic muscle plane block as a routine strategy for cardiac enhanced recovery after surgery in...

The aim of this study is to retrospectively analyze and evaluate the effect of transverse thoracic muscle plane (TTP) block as a routine analgesic strategy for cardiac enhanced recovery after surgery in sternotomy.Patients received TTP block after general anesthesia and tracheal intubation were included in this study. The baseline clinical data of the patients, intraoperative use of sufentanil, internal mammary artery separating time, the postoperative duration of invasive ventilation, visual analogue scale, the compression times of patient-controlled intravenous analgesia in the first 3 days after surgery, and postoperative nausea and vomiting were recorded.A total of 104 cases was included and divided to G group (without TTP block) and TTP group (with TTP). Sufentanil use (sufentanil dose/min, sufentanil dose/kg body weight, sufentanil dose/[min kg]) in TTP group was significantly lower than that of G group. In G group, intraoperative use of sufentanil was correlated to the duration of anesthesia (P = .035). The postoperative visual analogue scale pain scores and the compression times of patient-controlled intravenous analgesia in the TTP group were significantly decreased compared with G group (P < .01). The postoperative duration of invasive ventilation of patients with normal and mildly impaired pulmonary function was significantly correlated to the use of sufentanil (P = .027, .009).TTP block has certain analgesic effect and can reduce sufentanil use in medium-length cardiac surgery and postoperative use of opioids. It is indicated that TTP block can be used as a routine enhanced recovery after surgery strategy for sternotomy in cardiac surgery.
