Role of tranexamic acid in craniosynostosis surgery: Systematic review and meta-analysis

Perioperative Care for Children With Syndromic Craniofacial Synostosis Undergoing Le Fort III Surgery: A Retrospective Cohort Study

OBJECTIVE

To present characteristics, surgical variables, complications, and postoperative care in pediatric patients with craniofacial synostosis undergoing Le Fort III osteotomy.

BACKGROUND

Craniofacial synostoses are a group of genetic syndromes that result in premature fusion of cranial and facial sutures, leading to craniofacial deformities and associated complications. Midface advancement through Le Fort III osteotomy is the most frequent surgical option for these conditions.

METHODS

Retrospective monocentric cohort study including patients with syndromic craniofacial synostosis who underwent Le Fort III osteotomy between 2009 and 2022 in a specialized referral center. Data collection encompassed surgical time, blood loss, intraoperative transfusions, fluid balance, and postoperative parameters such as duration of invasive mechanical ventilation and intensive care unit (ICU) length of stay.

RESULTS

Twenty-six children were included in the analysis. The median surgical time was 345 minutes (300-360), with an estimated blood loss of 15 (9.9-24) mL/kg. Patients required a median transfusion of 12.63 (7.1-24.5) mL/kg of packed red blood cells and 19.82 (11.1-33) mL/kg of fresh frozen plasma. Intraoperative fluid balance was + 12.5 (0.8-22.8) mL/kg, with a median infusion of 30.4 (23.9-38.7) mL/kg of crystalloids. All patients were transferred to the ICU after surgery to ensure a safe environment for extubation. The median duration of mechanical ventilation in the ICU was 30 (20.25-45) hours, and postoperative ICU length of stay was 2 (2-4) days, and complications were infrequent, with only one extubation failure recorded.

CONCLUSION

Le Fort III osteotomy in craniofacial synostosis patients may be characterized by a complex perioperative course. A multidisciplinary approach in the care of these patients allows for minimizing complications in the perioperative phase. Further research is needed to enhance perioperative management in this unique patient population.

The early postoperative effects of rinsing the breast pocket with tranexamic acid in prepectoral prosthetic breast reconstruction

BACKGROUND

The efficacy of tranexamic acid (TXA) has been reported in breast surgery; however, its application and duration have varied across studies. This study aimed to assess the early postoperative outcomes of rinsing the breast pocket with TXA during prepectoral prosthetic breast reconstruction using an acellular dermal matrix (ADM).

METHODS

A retrospective chart review was conducted in consecutive patients who underwent immediate prosthetic prepectoral reconstruction between August 2021 and December 2022. For cases performed during the earlier part of the study period (up to April 2022), TXA was not administered (non-TXA group), whereas those performed after April 2022 received topical TXA application during surgery (TXA group). Postoperative outcomes including hematoma, seroma, drainage volume, and drain maintenance duration were compared between the two groups using propensity score matching (PSM).

RESULTS

A total of 674 breasts were analyzed; 280 in the TXA group and 394 were in the non-TXA group. There were 251 breasts in each group after PSM, and their characteristics were similar. The incidence of hematoma in the first 24 hours and total drain output were significantly lower in the TXA group than the non-TXA group. In cases of direct-to-implant cases, the TXA group showed a significantly lower seroma rate.

CONCLUSIONS

Rinsing the breast pocket with TXA can potentially reduce the occurrence of hematoma and decrease drain output in prepectoral ADM-assisted prosthetic breast reconstruction. Moreover, this approach may be beneficial in lowering the incidence of seroma in direct-to-implant reconstruction.

Intravenous Application of Tranexamic Acid in Patients Undergoing Plastic Surgery: A Systematic Review and Meta-analysis with GRADE Quality Assessment

BACKGROUND

Tranexamic acid (TXA) is a versatile antifibrinolytic agent that is widely used in modern surgeries. This review assessed the safety and efficacy of intravenous (IV) TXA in plastic surgery versus controls.

METHODS

This review selected English-language Randomized controlled trials (RCTs) evaluating IV TXA effects in plastic surgery from four electronic databases, PubMed, Web of Science, Embase, and Cochrane Library up to April 9, 2023. Primary outcomes were blood loss volume (BLV) and transfusion occurrence, with operation time and surgical field assessment as secondary outcomes. IV TXA-related complications were also important indicators. Meta-analyses and qualitative analyses were conducted and the quality of the evidence was assessed.

RESULTS

Thirty RCTs with 2150 patients were included. The total standard mean difference (SMD) of BLV and pooled relative risk of transfusion occurrence between the IV TXA and the control groups were - 1.11 (95% CI, - 1.42 to - 0.80) and 0.36 (95% CI, 0.23 to 0.55) respectively, indicating a significant blood loss reduction with IV TXA treatment, while an ambiguous outcome of operation time was observed, with an SMD of - 0.22 (95% CI, - 0.42 to - 0.02). The quality of evidence for BLV and transfusion occurrence was low and medium, respectively. A quantitative analysis of surgical field assessment was not performed because of the substantial heterogeneity in scoring methods. No IV TXA-related complications were observed.

CONCLUSIONS

In plastic surgery, IV TXA administration results in less blood loss, reduced need for transfusion and better surgical fields but probably does not increase the risk of adverse events.
