Abstract
Surgical correction of craniosynostosis can involve significant blood loss. Rates of allogenic blood transfusion have been reported to approach 100%. Multiple interventions have been described to reduce blood loss and transfusion requirements. The aim of this study was to analyze various approaches over the last 4 decades to optimize blood loss and management during craniosynostosis surgery. PRISMA guidelines for systematic reviews were followed. PubMed and Cochrane database searches identified studies analyzing approaches to minimizing blood loss or transfusion rate in craniosynostosis surgery. Primary outcomes included rate or amount of allogenic or autologous blood transfusion, estimated blood loss (EBL), postoperative hemoglobin (Hg), or hematocrit (Hct) levels. Secondary outcomes were examined when reported. Fifty-two studies met inclusion criteria. There was marked heterogeneity regarding design, inclusion criteria, surgical intervention, and endpoints. The majority of the studies were nonrandomized and noncomparative. Four studies analyzed erythropoietin (EPO), 6 analyzed various cell-saver (CS) technologies, 18 analyzed antifibrinolytics (tranexamic acid [TXA], aminocaproic acid [ACA], and aprotinin [APO]), 8 analyzed various alternatives, and 16 analyzed multimodal pathways & protocols. Some studies analyzed multiple approaches. Although the majority of studies reviewed represent level III/IV evidence, several high-quality level I studies were identified and included. Level I evidence supported an improvement in blood outcomes by utilizing EPO, CS, and TXA, individually or in concert with one another. Thus, this review suggests that a multi-prong approach may be the most effective means to optimize blood loss and transfusion outcomes in craniosynostosis surgery.

Tranexamic Acid Dosing in Craniosynostosis Surgery: A Systematic Review with Meta-analysis. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2022; 10:e4526. [PMID: 36262683 PMCID: PMC9575957 DOI: 10.1097/gox.0000000000004526] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 07/27/2022] [Indexed: 11/26/2022]
Abstract
This study aimed to compare operative time, blood loss, and transfusion requirement in patients receiving a high tranexamic acid (TXA) dose of greater than 10 mg/kg versus those receiving a low dose of 10 mg/kg or less. Methods PubMed, Cochrane Central, and Embase were queried to perform a systematic review with meta-analysis. Studies reporting outcomes of TXA use in craniosynostosis surgery were included. TXA dosing, operative time, blood loss, and transfusion requirement were the primary outcomes studied. Other variables studied included age and types of craniosynostosis. Results In total, 398 individuals in the included articles received TXA for craniosynostosis surgery. TXA loading doses ranged from 10 mg/kg to 50 mg/kg. Overall, administration of TXA was not associated with changes in operative time, but was associated with decreased blood loss and transfusion requirement on meta-analysis. Comparison of high dose TXA (>10 mg/kg) versus low dose (10 mg/kg or less) showed no statistical differences in changes in operative time, blood loss, or transfusion requirement. Conclusions Overall, TXA reduced blood loss and transfusion requirement in patients undergoing surgery for craniosynostosis. There was no difference in outcomes between high dose and low dose regimens amongst those receiving TXA. Low dose TXA appears adequate to achieve clinical efficacy with a low adverse event rate.

Abstract
Abstract
Background We compared intraoperative and postoperative anesthetic parameters between simple (S-single suture) and complex (C-more than one suture) craniosynostosis cases.
Materials and Methods Data was collected from a retrospective review of anesthetic and postoperative records of patients who underwent craniosynostosis correction surgery between April 2014 and August 2019. Pearson’s chi-square and independent sample t-tests were used for analysis.
Results We analyzed data of 98 patients (S-simple craniosynostosis: 40 and C-complex craniosynostosis: 58). Statistically significant differences between simple and complex cases were seen only in the incidence of difficult airway, failed extubation, and requirement of postoperative ventilation. Massive blood loss (S: 23.21 mL/kg; C: 22.71 mL/kg) and difficult airway (S: 2.04%; C: 19.39%) were the most common intraoperative adverse events encountered. Metabolic abnormalities, hemodynamic instability, and hypothermia occurred in few patients. The most common postoperative issue was pyrexia (S: 15.31%; C: 17.35%). Anemia and coagulopathy needing transfusion of blood products and vitamin K injection were seen in a significant number of cases. Three nonsyndromic patients developed seizures.
Conclusion The incidence of difficult airway and failed extubation with postoperative ventilation is more frequent following surgery for complex craniosynostosis than simple craniosynostosis. Complications secondary to blood loss and airway issues were the primary cause of morbidity and mortality. A staged approach to surgical management resulted in decreased surgical blood loss among the children with complex craniosynostosis.

Abstract
Congenital cardiac malformations have been reported in 8% of patients with craniosynostosis undergoing cranial vault remodeling (CVR), but associations with surgical outcomes are unknown. This study evaluated postoperative complications in patients who underwent CVR for craniosynostosis with or without cardiac risk factors (CRF) using the National Safety Quality Improvement Program-Pediatric (NSQIP-P) database. NSQIP-P database was queried for patients <2 years with craniosynostosis who underwent CVR from 2012 to 2016 based on diagnosis and procedure codes. The primary outcome was a composite of available NSQIP-P complications. Analysis compared patients with craniosynostosis based on the presence or absence of CRF. Univariate and multiple logistic regression identified risk factors associated with postoperative complications. A total of 3293 patients met inclusion criteria (8% with CRF). Two-thirds of patients experienced at least 1 complication, though patients with CRF experienced a greater proportion (74% vs 66%, P = 0.001). Univariate analysis identified associations between post-operative complications and age, ASA class, supplemental oxygen, neuromuscular disorders, preoperative nutritional supplementation, interventricular hemorrhage, and CRF. On multivariate regression, only older age (OR 1.17, 95% CI 1.01-1.36) and longer operative duration (OR 1.01, 95% CI 1.01-1.01) were associated with greater odds of postoperative complications. The most common complication in patients with craniosynostosis who undergo CVR is bleeding requiring transfusion. Older age and longer operative duration were associated with postoperative complications. Although patients with CRF have more postoperative complications, CRF was not a risk factor on adjusted analysis.

Abstract
OBJECTIVE In this paper the authors review their 16-year single-institution consecutive patient experience in the endoscopic treatment of nonsyndromic craniosynostosis with an emphasis on careful review of any associated treatment-related complications and methods of complication avoidance, including preoperative planning, intraoperative management, and postoperative care and follow-up. METHODS A retrospective chart review was conducted on all patients undergoing endoscopic, minimally invasive surgery for nonsyndromic craniosynostosis at Rady Children's Hospital from 2000 to 2015. All patients were operated on by a single neurosurgeon in collaboration with two plastic and reconstructive surgeons as part of the institution's craniofacial team. RESULTS Two hundred thirty-five patients underwent minimally invasive endoscopic surgery for nonsyndromic craniosynostosis from 2000 to 2015. The median age at surgery was 3.8 months. The median operative and anesthesia times were 55 and 105 minutes, respectively. The median estimated blood loss (EBL) was 25 ml (median percentage EBL 4.2%). There were no identified episodes of air embolism or operative deaths. One patient suffered an intraoperative sagittal sinus injury, 2 patients underwent intraoperative conversion of planned endoscopic to open procedures, 1 patient experienced a dural tear, and 1 patient had an immediate reexploration for a developing subgaleal hematoma. Two hundred twenty-five patients (96%) were admitted directly to the standard surgical ward where the median length of stay was 1 day. Eight patients were admitted to the intensive care unit (ICU) postoperatively, 7 of whom had preexisting medical conditions that the team had identified preoperatively as necessitating a planned ICU admission. The 30-day readmission rate was 1.7% (4 patients), only 1 of whom had a diagnosis (surgical site infection) related to their initial admission. Average length of follow-up was 2.8 years (range < 1 year to 13.4 years). Six children (< 3%) had subsequent open procedures for perceived suboptimal aesthetic results, 4 of whom (> 66%) had either coronal or metopic craniosynostosis. No patient in this series either presented with or subsequently developed signs or symptoms of intracranial hypertension. CONCLUSIONS In this large single-center consecutive patient series in the endoscopic treatment of nonsyndromic craniosynostosis, significant complications were avoided, allowing for postoperative care for the vast majority of infants on a standard surgical ward. No deaths, catastrophic postoperative morbidity, or evidence of the development of symptomatic intracranial hypertension was observed.

Abstract
OBJECTIVE To compare minimally invasive endoscopic and open surgical procedures, to improve informed consent of parents, and to establish a baseline for further targeted improvement of surgical care, this study evaluated the complication rate and blood transfusion rate of craniosynostosis surgery in our department. METHODS A prospective complication registration database that contains a consecutive cohort of all pediatric neurosurgical procedures in the authors' neurosurgical department was used. All pediatric patients who underwent neurosurgical treatment for craniosynostosis between February 2004 and December 2014 were included. In total, 187 procedures were performed, of which 121 were endoscopically assisted minimally invasive procedures (65%). Ninety-three patients were diagnosed with scaphocephaly, 50 with trigonocephaly, 26 with plagiocephaly, 3 with brachycephaly, 9 with a craniosynostosis syndrome, and 6 patients were suffering from nonsyndromic multisutural craniosynostosis. RESULTS A total of 18 complications occurred in 187 procedures (9.6%, 95% CI 6.2-15), of which 5.3% (n = 10, 95% CI 2.9-10) occurred intraoperatively and 4.2% (n = 8, 95% CI 2.2-8.2) occurred postoperatively. In the open surgical procedure group, 9 complications occurred: 6 intraoperatively and 3 postoperatively. In the endoscopically assisted procedure group, 9 complications occurred: 4 intraoperatively and 5 postoperatively. Blood transfusion was needed in 100% (n = 66) of the open surgical procedures but in only 21% (n = 26, 95% CI 15-30) of the endoscopic procedures. One patient suffered a transfusion reaction, and 6 patients suffered infections, only one of which was a surgical site infection. A dural tear was the most common intraoperative complication that occurred (n = 8), but it never led to postoperative sequelae. Intraoperative bleeding from a sagittal sinus occurred in one patient with only minimal blood loss. There were no deaths, permanent morbidity, or neurological sequelae. CONCLUSIONS Complications during craniosynostosis surgery were relatively few and minor and were without permanent sequelae in open and in minimally invasive procedures. The blood transfusion rate was significantly reduced in endoscopic procedures compared with open procedures.

Abstract
BACKGROUND Surgical correction for craniosynostosis is often associated with significant perioperative hemorrhage. We implemented a transfusion strategy with a strict protocol including transfusion triggers, frequent assessment of coagulation tests, and the use of a novel transfusion unit, the mixed pediatric unit. AIM The aim of the study was to evaluate if the applied transfusion strategy could reduce total blood loss and number of blood donors. METHODS Children <1 year old admitted for craniosynostosis surgery were included for the study. On the day before surgery, an adult red blood cell unit was mixed with plasma and split into two mixed pediatric units-one intended for intraoperative use and the other saved for the postoperative period. A series of blood samples were obtained for standard coagulation parameters as well as thromboelastography to evaluate potential coagulopathy. Estimated blood loss, the number of additional standard packed red cell units opened in the first 24 h after surgery, the volume of fluid administered, and the total transfusion volumes were compared to a historical control group with similar age and characteristics. RESULTS Nineteen infants were included in the study group, and were compared to 21 historical controls. There was a significant reduction of intraoperative transfusion volume. Twelve patients were transfused postoperatively, but in 8 of these additional exposure to packed red cell donor blood was avoided by using the saved mixed pediatric unit. In the historical controls, a total of 10 packed red cell units were used in nine patients postoperatively. No additional transfusions of plasma, platelets, fibrinogen, or tranexamic acid were needed in either group, and the coagulation parameters including thromboelastography remained within their respective normal ranges in the study group. CONCLUSION For craniofacial surgery in infants, moderate perioperative blood loss and avoidance of coagulopathy is possible when a multifactorial approach is implemented. In this setting, intraoperative, but not total perioperative blood loss was reduced with the studied protocol. The study indicates that there may be a role for mixed pediatric units to reduce exposure to multiple donors although the reduction in total donor exposure was not significant.

Abstract
PURPOSE Recent interventions have aimed at reducing the need for blood transfusions in the perioperative period in patients with craniosynostosis undergoing cranial vault remodeling. However, little is known regarding whether the receipt of a blood transfusion influences the length of hospital stay. The purpose of this study was to assess whether the receipt of a blood transfusion in patients undergoing cranial vault remodeling is associated with an increased length of stay. MATERIALS AND METHODS To address the research purposes, we designed a retrospective cohort study using the 2014 Pediatric National Surgical Quality Improvement Program (NSQIP Peds) dataset. The primary predictor variable was whether patients received a blood transfusion during cranial vault remodeling. The primary outcome variable was length of hospital stay after the operation. The association between the receipt of blood transfusions and length of stay was assessed using the Student t test. The association between other covariates and the outcome variable was assessed using linear regression, analysis of variance, and the Tukey test for post hoc pair-wise comparisons. RESULTS The sample was composed of 756 patients who underwent cranial vault remodeling: 503 who received blood transfusions and 253 who did not. The primary predictor variable of blood transfusion was associated with an increased length of stay (4.1 days vs 3.0 days, P = .03). Other covariates associated with an increased length of stay included race, American Society of Anesthesiologists status, premature birth, presence of a congenital malformation, and number of sutures involved in craniosynostosis. CONCLUSIONS The receipt of a blood transfusion in the perioperative period in patients with craniosynostosis undergoing cranial vault remodeling was associated with an increased length of stay.
