Survey of Parent Experiences in Prenatal Visits for Infants With Cleft Lip and Palate.

OBJECTIVE: The purpose of this study was to identify the factors that influence the parent's choice of cleft team/surgeon. DESIGN: A 10-question survey was used to elucidate factors that influenced parents in choosing their cleft surgeon. No identifiers of the origin of the study were used to improve parent objectivity. SETTING: The setting for this study was an online survey. PARTICIPANTS: Participants in this study were the parents of children who were born with cleft lip and/or palate. INTERVENTIONS: Parents were contacted anonymously via national, established social media websites that were independently run by the parents themselves. MAIN OUTCOME MEASURES: The main outcome measures were information regarding choice of cleft team/surgeon, source of patient referrals, and use of online media in decision making. RESULTS: A total of 112 responses were received. Of the parents, 77% sought prenatal evaluation with at least one cleft surgeon. Maternal-fetal medicine specialists were the most frequent (42%) referral source, followed by primary obstetricians (14%) and pediatricians (12%). The surgeon/cleft team's experience level and overall personality were ranked as the most important, whereas the least important was distance traveled. Of the parents, 95% used the Internet or social media for research prior to their prenatal visit; 96% of the parents found the prenatal visit helpful, and the most useful topics discussed were treatments (surgical, nonsurgical) and feeding techniques. CONCLUSION: This study identifies factors used to choose a cleft team/surgeon. Parents are more concerned with the experience level, reputation, and environment of the cleft team/surgeon than the distance traveled to get to the center.

Admission rapid thrombelastography can replace conventional coagulation tests in the emergency department: experience with 1974 consecutive trauma patients.

OBJECTIVE: Injury and shock lead to alterations in conventional coagulation tests (CCTs). Recently, rapid thrombelastography (r-TEG) has become recognized as a comprehensive assessment of coagulation abnormalities. We have previously shown that admission r-TEG results are available faster than CCTs and predict pulmonary embolism. We hypothesized that r-TEGs more reliably predict blood component transfusion than CCTs. METHODS: Consecutive patients admitted between September 2009 and February 2011 who met the highest-level trauma activations were included. All had admission r-TEG and CCTs. We correlated r-TEG values [activated clotting time (ACT), r, k, α, maximal amplitude (MA), LY30] with their corresponding CCTs [prothrombin time (PT)/activated partial thromboplastin time (aPTT), international normalized ratio (INR), platelet count and fibrinogen] for transfusion requirements. Charges were calculated for each test. Demographics, vital signs, and injury severity were recorded. RESULTS: We studied 1974 major trauma activations. The median injury severity score was 17 [interquartile range 9-26]; 25% were in shock; 28% were transfused; and 6% died within 24 hours. Overall, r-TEG correlated with CCTs. When controlling for age, injury mechanism, weighted-Revised Trauma Score, base excess and hemoglobin, ACT-predicted red blood cell (RBC) transfusion, and the α-angle predicted massive RBC transfusion better than PT/aPTT or INR (P < 0.001). The α-angle was superior to fibrinogen for predicting plasma transfusion (P < 0.001); MA was superior to platelet count for predicting platelet transfusion (P < 0.001); and LY-30 (rate of amplitude reduction 30 minutes after the MA is reached) documented fibrinolysis. These correlations improved for transfused, shocked or head injured patients. The charge for r-TEG ($317) was similar to the 5 CCTs ($286). CONCLUSIONS: The r-TEG data was clinically superior to results from 5 CCTs. In addition, r-TEG identified patients with an increased risk of early RBC, plasma and platelet transfusions, and fibrinolysis. Admission CCTs can be replaced with r-TEG.

Closed-loop control of fluid therapy for treatment of hypovolemia.

Closed-loop algorithms and resuscitation systems are being developed to control IV infusion rate during early resuscitation of hypovolemia. Although several different physiologic variables have been suggested as an endpoint to guide fluid therapy, blood pressure remains the most used variable for the initial assessment of hemorrhagic shock and the treatment response to volume loading. Closed-loop algorithms use a controller function to alter infusion rate inversely to blood pressure. Studies in hemorrhaged conscious sheep suggest that: (1) a small reduction in target blood pressure can result in a significant reduction in volume requirement; (2) nonlinear algorithms may reduce the risk of increased internal bleeding during resuscitation; (3) algorithm control functions based on proportional-integral, fuzzy logic, or nonlinear decision tables were found to restore and maintain blood pressure equally well. Proportional-integral and fuzzy logic algorithms reduced mean fluid volume requirements compared with the nonlinear decision table; and (4) several algorithms have been constructed to the specific mechanism of injury and the volume expansion properties of different fluids. Closed-loop systems are undergoing translation from animal to patient studies. Future smart resuscitation systems will benefit from new noninvasive technologies for monitoring blood pressure and the development of computer controlled high flow intravenous pumps.
