Blood transfusion following major orthopaedic surgery in cerebral palsy: a retrospective analysis

The Effect of Tranexamic Acid on Estimated Blood Loss and Transfusion Rates in Children with Cerebral Palsy Undergoing Single-Event Multi-Level Surgery, a Retrospective Study

Purpose: Multiple osteotomies are frequently associated with single-event multi-level surgery (SEMLS) in children with cerebral palsy (CP). However, appropriate management of perioperative blood loss is crucial for decreasing the length of hospital stay and early rehabilitation. Tranexamic acid (TxA) has been proven to significantly reduce perioperative bleeding in multiple major orthopedic surgeries. The aim of this study was to investigate the effectiveness of TxA in decreasing blood loss in children with CP undergoing SEMLS procedures. Materials and Methods: Between September 2016 and September 2022, 101 consecutive children with CP who underwent SEMLS were identified-50 patients did not receive TxA peri-operatively (Control Group, from September 2016 to September 2018), and 51 patients received TxA (TxA Group since September 2018). Bleeding, hemoglobin levels, transfusion rate, length of hospital stay and postoperative hematocrit were compared between the groups. The predictive factors of blood transfusion were determined. Results: The transfusion rate significantly decreased in the TxA Group (43.3% vs. 4%, p < 0.001). The use of TxA and epidural analgesia were the identified factors for a significant transfusion rate decrease. Bleeding (estimated red cell loss) was decreased in the TxA group in comparison to the control group 22.3 [17.3-27.3] versus 33.78 [27.4-40.2], p < 0.05). The hospital length of stay significantly decreased in the TxA group (7.3 vs. 6 days, p = 0.01). No TxA-related complications occurred in any of the patients. Conclusions: A blood loss prevention strategy based on a low dose of TxA in children scheduled for SEMLS significantly decreased bleeding and transfusion rates, allowing an earlier discharge from the hospital for patients.

Blood loss in hip reconstructive surgery in children with cerebral palsy: when do I need to be prepared for blood transfusion?

The hip is the second most common joint involved in pediatric patients with cerebral palsy (CP). Hip reconstructive procedures are performed to improve function and comfort level. Blood loss can occur leading to blood transfusion in close to 1/3 of children with CP undergoing hip reconstruction. The purpose of this study was to report the rate and risk factors for blood transfusion after hip reconstruction in a large cohort of children with CP. We conducted a retrospective chart review of pediatric patients at our tertiary referral children's hospital who underwent reconstructive hip osteotomy over an 8-year period. Binary logistic regression was employed to compare and model differences in transfusion between age greater than 4 or 6 years and the number of osteotomies. A total of 180 patients met our inclusion criteria. Thirty-seven patients (20.6%) received blood transfusion. Incidence of transfusion increased as number of osteotomies increased from 1 to 4 (3.7%, 7.3%, 34.0%, 58.3%, respectively). We did not find a significant effect of age greater than 4 or 6 years on the rate of blood transfusion (P = 0.676 and P = 0.323, respectively). The number of osteotomies was a significant factor in the rate of blood transfusion in both models (P < 0.001). Number of osteotomies and not age was a significant risk factor in the rate of blood transfusion. This data can help the orthopedic surgeons in preoperative planning for the possibility of blood transfusion in these patients.

Perioperative blood conservation strategies for pediatric scoliosis surgery

PURPOSE

Many pediatric patients with severe scoliosis requiring surgery have baseline anemia. Pediatric scoliosis fusion surgery is associated with perioperative blood loss requiring transfusion. As such, many patients in this surgical population could benefit from a perioperative blood conservation program.

METHODS

Here we present a narrative review of perioperative blood conservation strategies for pediatric scoliosis surgery involving nurses, transfusion medicine physicians, anesthesiologists, surgeons, dieticians, perfusionists and neurophysiologists spanning the pre-, intra- and postoperative phases of care.

RESULTS

The review highlights how perioperative blood conservation strategies, have the potential to minimize exposures to exogenous blood products. Further, we describe a relevant example of blood conservation related to the care of a Jehovah's Witness patient undergoing staged scoliosis repair. Lastly, we outline areas which would benefit from clinical studies to further elucidate perioperative blood conservation interventions and their outcomes relevant to pediatric scoliosis surgery patients.

CONCLUSION

Interdisciplinary communication and meticulous blood conservation strategies are proving to be a means of reducing if not eliminating the need for allogeneic blood products for surgical correction of pediatric scoliosis.
