    ABSTRACT: Surgical correction of craniosynostosis in children is associated with substantial intraoperative bleeding. Tranexamic acid (TXA) decreases intraoperative blood loss during cardiac or orthopedic surgery in children. We hypothesized that intraoperative TXA would reduce blood transfusion relative to placebo in patients pretreated with erythropoietin. Forty consecutive children, American Society of Anesthesiologists status 1 or 2, scheduled to undergo surgical correction of craniosynostosis were randomly assigned to receive either intravenous TXA or saline, 0.9%, intraoperatively. All children received preoperative erythropoietin (600 U/kg once a week for 3 weeks before surgery). Perioperative blood loss, number and volume of transfusions, percentage of children who underwent transfusion, and side effects were noted after surgery and at the end of the study. Surgeon satisfaction and cost of treatment were also recorded. There was no significant difference between groups in demographic or surgical data. In the TXA group, the volume of packed erythrocytes transfused was significantly reduced by 85% (from 11 to 1.6 ml/kg) intraoperatively and by 57% (from 16.6 to 7.2 ml/kg) throughout the study period (P < 0.05). Compared with the placebo group, the percentage of children requiring blood transfusion was lower in the TXA group during surgery (9 [45%] of 20 vs. 2 [11%] of 19 children; P < 0.05) and during the whole study period (14 [70%] of 20 vs. 7 [37%] of 19; P < 0.05). Preoperative and postoperative hematologic parameters were comparable in both groups. There were no adverse events. In children undergoing surgical correction of craniosynostosis and pretreated with erythropoietin, intraoperative TXA reduces the transfusion requirement.

    ABSTRACT: Congenital cleft palate (CP) is a common and painful surgical procedure in infants. CP repair is associated with the risk of postoperative airway obstruction, which may be increased with administration of opioids, often needed for analgesia. No described regional anesthesia technique can provide adequate pain control following CP repair in infants. The primary aim of this prospective and descriptive study was to observe the effectiveness of bilateral maxillary nerve blocks (BMB) using a suprazygomatic approach on pain relief and consumption of rescue analgesics following CP repair in infants. Analgesic consumption was compared to retrospective data. Complications related to this new technique in infants were also reviewed. The landmarks and measurements recently defined in a three-dimensional study using computed tomography in infants were used. After general anesthesia, a BMB was performed bilaterally with 0.15 ml x kg(-1) 0.2% ropivacaine in infants scheduled for CP repair. Postoperative analgesia, administration of rescue analgesics, adverse effects, and time to feed were recorded in the 48-h period following surgery and compared to retrospective data. Thirty-three children, mean age 5 +/- 1.8 months and weight 8.3 +/- 1.2 kg, were studied. Eighteen patients out of 33 (55%) did not require additional opioids intra-operatively, vs two out of 20 (10%) without block. None needed morphine postoperatively, and intravenous nalbuphine was required in only six children (18%), vs 16 (80%) without block. Median time to feed was 8 h (range 2-24 h), vs 13 h (4-25) without block. No technical failure or complication related to the BMB was reported. BMB using a suprazygomatic approach seems to improve pain relief, to decrease peri-operative consumption of opioids, and to favor early feeding resumption after CP repair in infants.
