To assess whether a preoperative bilateral thoracic paravertebral block (TPVB) would improve postoperative analgesia in infants and small children undergoing open cardiac surgery in the protocol of an ultra-fast track cardiac anesthesia (UFTCA). A single-center, prospective, randomized, controlled study. At a tertiary children's medical center. A total of 180 children undergoing cardiac surgery, aged 1 month to 3 years. Patients are allocated randomly to TPVB and parent- and/or nurse-controlled intravenous analgesia (PNCA) group (Group T) or PNCA group (Group P). The primary outcome is the postoperative pain scores. The secondary outcome are intraoperative consumption of sufentanil, time to extubation, using of neostigmine, cumulative total and invalid PCA attempts in 24 and 48 hours after surgery, hospitalization characteristics, perioperative blood glucose, postoperative arterial oxygen partial pressure, arterial carbon dioxide partial pressure (PaCO2) and brain natriuretic peptide (BNP). The postoperative pain scores within 24 hours, intraoperative consumption of sufentanil, total, and invalid PCA attempts in 24 and 48 hours, perioperative blood glucose and BNP on the seventh day in Group T were all significantly lower than those in Group P (p < 0.001). The time to extubation, the use of neostigmine, and PaCO2 on the sixth hour, postoperatively, were significantly smaller in Group T than those in Group P (p < 0.05). There were no significant differences in the hospitalizations between the 2 groups. A combination of bilateral single dose TPVB and PNCA pain management is superior to a PNCA pain management alone in infants and small children undergoing open cardiac surgery and contributes to a rapid recovery with preferable perioperative outcomes in the protocol of UFTCA.
