Objective: Patients presenting with total body surface area (TBSA) >40% burns require significant surgical treatment. Two substantial challenges during these surgeries are limiting blood loss and maintaining core temperatures. To overcome these challenges, several techniques have been developed, ranging from the Pitkin syringe method to the pneumatic tourniquet strategy for large-volume hyperthermic insufflation. Here, we compare the pneumatic tourniquet method to a roller pump method for maintenance of intraoperative normothermia and control of bleeding. Methods: We conducted a retrospective chart review of 20 patients presenting with TBSA >40% burns, 10 of whom were treated with the rapid infusion roller pump and 10 of whom were treated with the pneumatic tourniquet technique. Patients from each group were controlled for % TBSA, presence of inhalation injury, age, and date of admission. We reviewed transfusion requirement and the intraoperative temperatures, as well as the average intraoperative drop in temperature. Results: We observed improvement in the infusion volume, operative time, intraoperative temperature drop, minimum intraoperative temperature, estimated blood loss, and amount of required transfusion. Conclusions: Our study suggests that the rapid infusion roller pump technique is capable of achieving superior intraoperative bleeding control and temperature maintenance compared to the pneumatic tourniquet technique, resulting in decreased transfusion requirement.

Abstract Introduction Prior studies of burn patients with < 20% total body surface area (TBSA) burns have found that 15.4% of patients have major psychiatric illness (MPI) and 27.6% have Substance Use Disorder (SUD). In patients with small burns, SUD is associated with larger burn size and secondarily with longer length of stay while MPI is associated with longer lengths of stay while not increasing burn size. The purpose of this study was to determine whether MPI or SUD dependence affects outcomes such as mortality in patients with major burn injuries (≥20% TBSA). Methods A secondary analysis from the prospective, randomized, multicenter Transfusion Requirement in Burn Care Evaluation (TRIBE) study was conducted. Patients with MPI and SUD were compared with patients without these disorders. Statistical analysis with chi-square for categorical variables and student’s t-test for continuous variables was conducted. Mortality between those with and without MPI and SUD were analyzed with a multivariable regression analysis. Results A total of 347 patients with a mean age of 43±17 years, 274 men and 73 women, were analyzed. The mean total body surface area burn (TBSA) was 38±18%, and 23% had inhalation injury. In this study population, 29.1% had SUD, 7.5% had MPI, and 2.3% had both. There was no difference with respect to age, gender, TBSA, frailty, or assignment to the liberal or restrictive transfusion strategy based on the presence of MPI, SUD, or both. Inhalation injury was more common in patients with MPI (27%) or SUD (35%) when compared with patients without these comorbidities (18%) or those who have both (11%) (p=0.006). Patients with MPI were more likely to die of their burn injuries (27%) when compared with those with SUD (17%), both (11%), or neither (8%) (p=0.014). On multivariate analysis for mortality controlling for TBSA and inhalation injury, MPI was found to be an independent predictor of death with an odds ratio of 5 (95% confidence interval 1.7–15, p=0.003). Conclusions In burns >20% TBSA, both MPI and SUD influence patient’s likelihood of sustaining inhalation injury. MPI is also independently associated with mortality in the study. Further work must be done to mitigate the effects of mental illness on burn outcomes.

AbstractBackground: The use of a tourniquet during total knee arthroplasty (TKA) continues to be a matter of debate. Advantages of tourniquet use include improved visualization, decreased intraoperative and total blood loss, and possibly decreased transfusion requirement. However, the recent widespread adoption of antifibrinolytic therapy with tranexamic acid (TXA), may negate these benefits. The purpose of this study was to evaluate perioperative blood loss and transfusion requirement with two different tourniquet application strategies, and surgery without the use of a tourniquet during routine, primary cemented TKA.Methods: A retrospective cohort study was performed of 300 patients undergoing TKA at a single institution after the implementation of a routine intravenous TXA administration protocol and consisted of three groups based on tourniquet usage: tourniquet inflation before incision and deflation following cement hardening (TQ), tourniquet inflation prior to cement application and deflation following hardening (Partial TQ), and no tourniquet usage (No TQ). Each group consisted of 100 consecutive patients. Perioperative blood loss, change in hematocrit and transfusion requirement were compared between groups. Results: Total blood loss (estimated blood loss and drain output) was lowest in the TQ group, however this was only due a slight decrease in intraoperative estimated blood loss. There was no difference in post-operative drain output, or change in hematocrit levels from preoperative values. There were no transfusions in the Partial TQ and No TQ groups, whereas there were 5 transfusions in the TQ group.Conclusions: In the era of routine TXA administration during TKA, tourniquet usage does not appear to have a benefit in regards to perioperative blood loss or transfusion requirement.

The purpose of this report is to introduce the technique of superselective embolization (SSE) and to review our experience in surgically treating glomus jugulare tumors with and without preoperative SSE. Retrospective chart review was performed to determine estimated blood loss and operative time, and illustrative case reports are presented. The technique of preoperative SSE represents an important advance in the surgical management of glomus jugulare tumors. In our experience, surgical ligation of tumor-feeding vessels or nonselective embolization of the external carotid system is unsatisfactory. Inadequate devascularization and excessive risk of complications have caused us and others to abandon these procedures. However, SSE performed by an experienced neuroradiologist can produce effective and safer tumor devascularization. Preoperative SSE results in shrinkage of tumor size and significantly decreases blood loss. The advantages to the surgeon include improved visualization and ease of dissection as well as increased confidence that complete tumor excision has been achieved.

Objective To evaluate the ability of estimated blood loss (EBL) and quantitative blood loss (qBL) to predict need for blood transfusion in women with postpartum hemorrhage (PPH). Study Design This is a retrospective chart review that identified women with PPH (>1,000 mL for vaginal or cesarean delivery) between September 2014 and August 2015, reported by EBL (n = 92), and October 2015 and September 2016, reported by qBL (n = 374). The primary metric was the area under the receiver-operating characteristic curve for blood transfusion. Results The rate of PPH by EBL and qBL was 2.8 and 10.8%, respectively (p < 0.01). The rate of transfusion for women meeting criteria for PPH by EBL and QBL were 2% (66/3,307) and 2.7% (93/3,453), respectively (p = 0.06). Postpartum transfusion was predicted by an EBL of 1,450 mL with AUC 0.826 and qBL 1,519 mL with AUC 0.764, for all modes of delivery. Postpartum vital signs and change in pre- and postdelivery hematocrit were poor predictors for transfusion. Conclusion The rates of PPH increased with the implementation of qBL. Overall, qBL did not perform better than EBL in predicting the need for blood transfusion.

Object Children with craniosynostosis may require cranial vault remodeling to prevent or relieve elevated intracranial pressure and to correct the underlying craniofacial abnormalities. The procedure is typically associated with significant blood loss and high transfusion rates. The risks associated with transfusions are well documented and include transmission of infectious agents, bacterial contamination, acute hemolytic reactions, transfusion-related lung injury, and transfusion-related immune modulation. This study presents the Children's Hospital of Richmond (CHoR) protocol, which was developed to reduce the rate of blood transfusion in infants undergoing primary craniosynostosis repair. Methods A retrospective chart review of pediatric patients treated between January 2003 and Febuary 2012 was performed. The CHoR protocol was instituted in November 2008, with the following 3 components; 1) the use of preoperative erythropoietin and iron therapy, 2) the use of an intraoperative blood recycling device, and 3) acceptance of a lower level of hemoglobin as a trigger for transfusion (< 7 g/dl). Patients who underwent surgery prior to the protocol implementation served as controls. Results A total of 60 children were included in the study, 32 of whom were treated with the CHoR protocol. The control (C) and protocol (P) groups were comparable with respect to patient age (7 vs 8.4 months, p = 0.145). Recombinant erythropoietin effectively raised the mean preoperative hemoglobin level in the P group (12 vs 9.7 g/dl, p < 0.001). Although adoption of more aggressive surgical vault remodeling in 2008 resulted in a higher estimated blood loss (212 vs 114.5 ml, p = 0.004) and length of surgery (4 vs 2.8 hours, p < 0.001), transfusion was performed in significantly fewer cases in the P group (56% vs 96%, p < 0.001). The mean length of stay in the hospital was shorter for the P group (2.6 vs 3.4 days, p < 0.001). Conclusions A protocol that includes preoperative administration of recombinant erythropoietin, intraoperative autologous blood recycling, and accepting a lower transfusion trigger significantly decreased transfusion utilization (p < 0.001). A decreased length of stay (p < 0.001) was seen, although the authors did not investigate whether composite transfusion complication reductions led to better outcomes.

Caloric Requirements

Abstract Introduction Caloric intake has been a vital component for burn wound healing and recovery. The hypothesis was that caloric requirements are based on injury severity & post-burn week as predicated by indirect calorimetry (IC)/predictive equations. Methods This was a retrospective chart review of 115 burn patients (2012–2017). Caloric requirements were determined by the Curreri equation [which includes % total body surface area (TBSA)] and IC for a 5-week period provided mainly by enteral nutrition. Patients received supplements and total parenteral nutrition as needed. Results The mean ±sd age was 43±18 years, 41±18 % TBSA, Body Mass Index of 28±7 kg/m2, and mortality of 26 (23%). The major mechanisms of injury were flame/flash/explosions. There were 59 (51%) of patients with &lt; 40 % TBSA burns, [median Injury Severity Score (ISS) 9; Apache score 14], and 56 (49%) with ≥40 % TBSA (median ISS 25; Apache score 21), p &lt; .0001. The Respiratory Quotient (RQ) had a median of 0.94 (range 0.79 to 1.02). The median number of surgeries for the &lt; 40 % TBSA group was 5 versus 12 for the ≥40 % TBSA, p &lt; .0001. The Injury Factor did not differ from weeks 1–5 (1.8 for &lt; 40 % TBSA and 2.0 for the ≥ 40 % TBSA). The Curreri equation calculation for this study was a median 3640 (range 2161–5950) calories. The Curreri equation resulted in significantly increased caloric recommendations for the ≥ 40 %TBSA compared to the &lt; 40 %TBSA patients, p &lt; .0001. The &lt; 40 %TBSA group had caloric requirements ranging between 1500- 2700 calories compared to the ≥ 40 %TBSA group, whose calories ranged between 2000–3700. The total daily caloric recommendations were also significantly increased in the ≥40 %TBSA compared to the &lt; 40 %TBSA patients. The maximum levels of resting energy expenditure (REE) from IC, total daily calories recommended by the dietitian and average calories ranged between 3000–4500 in the &lt; 40 %TBSA group and 3600–6700 in the ≥ 40 %TBSA group. The caloric recommendations increased for all patients from week 1 to week 3 and leveled off during weeks 4–5. Conclusions Patient caloric requirements were dependent not only on the severity of the burn injury but also the post-burn hospitalization during which surgeries, debridement/grafting, and infectious complications occurred. They increased until the third week post-burn and leveled off in the recovery period. The study caloric recommendations and requirements were consistent with the REE and Curreri equation assessments.

Abstract Introduction In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). Methods This was a multi-center retrospective study of adult patients at 7 burn centers admitted between January 1, 2016 and July 25, 2019 who had a 25-hydroxyvitamin D (25OHD) concentration drawn within the first 7 days of injury. Patients were excluded if admitted for a non-burn injury, total body surface area (TBSA) burn less than 5%, pregnant, incarcerated, or made comfort care or expired within 48 hours of admission. The primary endpoint was to compare hospital LOS between burn patients with vitamin D deficiency (defined as 25OHD &lt; 20 ng/mL) and sufficiency (25OHD ≥ 20 ng/mL). Secondary endpoints include in-hospital mortality, ventilator-free days of the first 28, renal replacement therapy (RRT), length of ICU stay, and days requiring vasopressors. Additional data collected included demographics, Charlson Comorbidity Index, injury characteristics, form of vitamin D received (ergocalciferol or cholecalciferol) and dosing during admission, timing of vitamin D initiation, and form of nutrition provided. Dichotomous variables were compared via Chi-square test. Continuous data were compared via student t-test or Mann-Whitney U test. Univariable linear regression was utilized to identify variables associated with LOS (p &lt; 0.05) to analyze further. Cox Proportional Hazard Model was utilized to analyze association with LOS, while censoring for death, and controlling for TBSA, age, presence of inhalation injury, and potential for a center effect. Results Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p &lt; 0.001), acute kidney injury (AKI) requiring RRT (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p &lt; 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, the best fit model included only deficiency and days until vitamin D initiation. Conclusions Patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with sufficient vitamin D concentrations.

Aim To assess the relationship of preoperative hematology laboratory results with intraoperative estimated blood loss and transfusion volumes during posterior spinal fusion for pediatric neuromuscular scoliosis. Methods Retrospective chart review of 179 children with neuromuscular scoliosis undergoing spinal fusion at a tertiary children’s hospital between 2012 and 2017. The main outcome measure was estimated blood loss. Secondary outcomes were volumes of packed red blood cells, fresh frozen plasma, and platelets transfused intraoperatively. Independent variables were preoperative blood counts, coagulation studies, and demographic and surgical characteristics. Relationships between estimated blood loss, transfusion volumes, and independent variables were assessed using bivariable analyses. Classification and Regression Trees were used to identify variables most strongly correlated with outcomes. Results In bivariable analyses, increased estimated blood loss was significantly associated with higher preoperative hematocrit and lower preoperative platelet count but not with abnormal coagulation studies. Preoperative laboratory results were not associated with intraoperative transfusion volumes. In Classification and Regression Trees analysis, binary splits associated with the largest increase in estimated blood loss were hematocrit ≥44% vs. <44% and platelets ≥308 vs. <308 × 109/L. Conclusions Preoperative blood counts may identify patients at risk of increased bleeding, though do not predict intraoperative transfusion requirements. Abnormal coagulation studies often prompted preoperative intervention but were not associated with increased intraoperative bleeding or transfusion needs.

Objectives: were to (a) determine incidence of postpartum hemorrhage (PPH) in all women delivering between 2009 and 2015, and (b) determine the amount of Estimated Blood Loss (EBL) and duration of the third stage of labor in each subgroup for women with or without PPH, and (c) compare EBL and duration of 3rd stage of labor between subgroups in groups of women with or without PPH. Design: A retrospective chart review conducted using codes for atonic PPH. Setting: Records from a University based tertiary setting, 264 charts were reviewed and data from 154 charts were analyzed. One-way ANOVAs followed with post-hocs and a 2-way ANOVA were conducted. Results: PPH rate increased by 47.50% from 2009–2015. For women with PPH, EBL was lower in skin to skin contact (SSC) + Breastfeeding (BF) subgroup. For women without PPH, EBL was lower in SSC only subgroup. Third stage of labor duration was longer in women with PPH. Conclusions: Study confirmed the increasing trends of PPH due to uterine atony and proposed role of SSC and BF in decreasing EBL and shorten the duration of the 3rd stage of labor for PPH women, usefulness of SSC and BF as physiologic practices merit further study.
