Hand ischemia associated with elbow trauma in children

ObjectivesPrevious observational studies suggest that children with hand ischemia following elbow trauma can be safely observed if Doppler signals are present in the wrist arteries (pink pulseless hand, PPH). Nonoperative management of PPH is predicated on the assumption that PPH results from local arterial spasm, but the mechanism of arterial compromise has not been investigated. We hypothesized that PPH signifies a brachial artery injury that requires surgical repair.MethodsRetrospective review of operations performed on children with hand ischemia following elbow trauma at a level I trauma center pediatric hospital.ResultsBetween 2003 and 2010, 12 children (seven males, mean age 7.4 years) underwent brachial artery exploration for hand ischemia following elbow trauma (11 supracondylar fractures, one elbow dislocation) due to falls (n = 10) or motor vehicle crashes (n = 2). At presentation, three subjects had normal radial pulses, eight subjects had Doppler signals but no palpable pulses, and one had weak Doppler flow with advanced hand ischemia. Six of the nine subjects without palpable pulses also had neurosensory changes. All 12 subjects underwent brachial artery exploration either initially (n = 2) or following orthopedic fixation (n = 10) due to persistent pulselessness. At operation, eight of 12 patients (67%) had focal brachial artery thrombosis due to intimal flaps, and four had brachial artery and median nerve entrapment within the pinned fracture site. At discharge, all 12 subjects had palpable radial pulses, but three with entrapment had dense median nerve deficits. One of the three subjects with dense neurologic deficit had complete recovery of neurologic function at ten months. The other two subjects had residual median nerve deficits with partial recovery at 5 and 6 months follow-up, respectively. No patient developed Volkman's contracture.ConclusionsBrachial artery injuries should be anticipated in children with hand ischemia associated with elbow trauma. Neurovascular entrapment at the fracture site is a possible complication of orthopedic fixation. Absence of palpable wrist pulses after orthopedic fixation should prompt immediate brachial artery exploration. PPH should not be considered a consequence of arterial spasm in these patients

Management of parapneumonic collections in infants and children

Background/Purpose: Video-assisted thoracoscopic surgery (VATS) has a recognized role in treatment of empyema thoracis. The purpose of this report is to show the value of initial VATS as the primary treatment of parapneumonic collections. Methods: A retrospective review was done of 139 children who required surgical consultation for parapneumonic collections between January 1992 and July 1998. Management options were (M1) thoracentesis, chest tube drainage, or fibrinolytic therapy and delayed thoracotomy for unresolved collections; (M2) thoracentesis, chest tube drainage, fibrinolytic therapy with delayed VATS if the child remained ill; or (M3) primary VATS. Comparative data included age, duration of prehospital illness, oxygen requirements, white blood cell count, bacterial culture results, number of procedures performed per patient, duration of chest tube drainage, complications, and length of stay. Kruskal-Wallis 1-way analysis was used, with significance at P less than .05. Results: A total of 60 children were treated by M1, 38 by M2, and 41 by M3. Age, duration of prehospital illness, oxygen requirements, white blood cell count, bacterial culture results, and complication rates were comparable. The median length of stay was 12 days for M1, 11 days for M2, and 7 days for M3, with M3 significantly shorter at P\u3c .001. The number of procedures was a median of 2 in M1, 2 in M2, and 1 in M3, with M3 significantly fewer at P \u3c .001. Duration of chest tube drainage was a median 5 days for M1 and 3 days for M2 and M3, with M1 significantly longer at P \u3c .001. There were 9 thoracotomies in the M1 group, 3 in the M2 group, and none in the M3 group. One child in M3 required a second VATS. Conclusions: Primary VATS has significantly decreased the number of procedures, duration of chest tube drainage and length of stay for children with parapneumonic effusions. Primary VATS appears to be of value in management of bacterial pneumonia with effusion. Copyright (C) 2000 by W.B. Saunders Company

Prospective Multicenter Study of Surgical Correction of Pectus Excavatum: Design, Perioperative Complications, Pain, and Baseline Pulmonary Function Facilitated by Internet-Based Data Collection

Background: Given widespread adoption of the Nuss procedure, prospective multicenter study of management of pectus excavatum by both the open and Nuss procedures was thought desirable. Although surgical repair has been performed for more than 50 years, there are no prospective multicenter studies of its management. Study Design: This observational study followed pectus excavatum patients treated surgically at 11 centers in North America, according to the method of choice of the patient and surgeon. Before operation, all underwent evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, hospital complications, and perioperative pain. One year after completion of treatment, patients will repeat the preoperative evaluations. This article addresses early results only. Results: Of 416 patients screened, 327 were enrolled; 284 underwent the Nuss procedure and 43 had the open procedure. Median preoperative CT index was 4.4. Pulmonary function testing before operation showed mean forced vital capacity of 90% of predicted values; forced expiratory volume in 1 second (FEV1), 89% of predicted; and forced expiratory flow during the middle half of the forced vital capacity (FEF25% to 75%), 85% of predicted. Early postcorrection results showed that operations were performed without mortality and with minimal morbidity at 30 days postoperatively. Median hospital stay was 4 days. Postoperative pain was a median of 3 on a scale of 10 at time of discharge; the worst pain experienced was the same as was expected by the patients (median 8), and by 30 days after correction or operation, the median pain score was 1. Because of disproportionate enrollment and similar early complication rates, statistical comparison between operation types was limited. Conclusions: Anatomically severe pectus excavatum is associated with abnormal pulmonary function. Initial operative correction performed at a variety of centers can be completed safely. Perioperative pain is successfully managed by current techniques

Increasing Severity of Pectus Excavatum Is Associated with Reduced Pulmonary Function

Objective To determine whether pulmonary function decreases as a function of severity of pectus excavatum, and whether reduced function is restrictive or obstructive in nature in a large multicenter study. Study design We evaluated preoperative spirometry data in 310 patients and lung volumes in 218 patients aged 6 to 21 years at 11 North American centers. We modeled the impact of the severity of deformity (based on the Haller index) on pulmonary function. Results The percentages of patients with abnormal forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory flow from 25% exhalation to 75% exhalation, and total lung capacity findings increased with increasing Haller index score. Less than 2% of patients demonstrated an obstructive pattern (FEV1/FVC \u3c67%), and 14.5% demonstrated a restrictive pattern (FVC and FEV1 \u3c80% predicted; FEV1/FVC \u3e80%). Patients with a Haller index of 7 are \u3e4 times more likely to have an FVC of ≤80% than those with a Haller index of 4, and are also 4 times more likely to exhibit a restrictive pulmonary pattern. Conclusions Among patients presenting for surgical repair of pectus excavatum, those with more severe deformities have a much higher likelihood of decreased pulmonary function with a restrictive pulmonary pattern

Multicenter study of pectus excavatum, final report: complications, static/exercise pulmonary function, and anatomic outcomes.

BackgroundA multicenter study of pectus excavatum was described previously. This report presents our final results.Study designPatients treated surgically at 11 centers were followed prospectively. Each underwent a preoperative evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, complications, and perioperative pain. One year after treatment, patients underwent repeat chest CT scan, pulmonary function tests, and body image survey. A subset of 50 underwent exercise pulmonary function testing.ResultsOf 327 patients, 284 underwent Nuss procedure and 43 underwent open procedure without mortality. Of 182 patients with complete follow-up (56%), 18% had late complications, similarly distributed, including substernal bar displacement in 7% and wound infection in 2%. Mean initial CT scan index of 4.4 improved to 3.0 post operation (severe >3.2, normal = 2.5). Computed tomography index improved at the deepest point (xiphoid) and also upper and middle sternum. Pulmonary function tests improved (forced vital capacity from 88% to 93%, forced expiratory volume in 1 second from 87% to 90%, and total lung capacity from 94% to 100% of predicted (p < 0.001 for each). VO2 max during peak exercise increased by 10.1% (p = 0.015) and O2 pulse by 19% (p = 0.007) in 20 subjects who completed both pre- and postoperative exercise tests.ConclusionsThere is significant improvement in lung function at rest and in VO2 max and O2 pulse after surgical correction of pectus excavatum, with CT index >3.2. Operative correction significantly reduces CT index and markedly improves the shape of the entire chest, and can be performed safely in a variety of centers

This study evaluated changes in both physical and psychosocial quality of life reported by the parent and child after surgical repair of pectus excavatum. METHODS. As part of a multicenter study of pectus excavatum, a previously validated tool called the Pectus Excavatum Evaluation Questionnaire was administered by the research coordinator, via telephone, to parents and patients (8–21 years of age) before and 1 year after surgery. Eleven North American children\u27s hospitals participated. From 2001 to 2006, 264 patients and 291 parents completed the initial questionnaire, and 247 patients and 274 parents completed the postoperative questionnaire. Responses used a Likert-type scale of 1 to 4, reflecting the extent or frequency of a particular experience, with higher values conveying less-desirable experience. RESULTS. Preoperative psychosocial functioning was unrelated to objective pectus excavatum severity (computed tomographic index). Patients and their parents reported significant positive postoperative changes. Improvements occurred in both physical and psychosocial functioning, including less social self-consciousness and a more-favorable body image. For children, the body image component improved from 2.30 ± 0.62 (mean ± SD) to 1.40 ± 0.42 after surgery and the physical difficulties component improved from 2.11 ± 0.82 to 1.37 ± 0.44. For the parent questionnaire, the child\u27s emotional difficulties improved from 1.81 ± 0.70 to 1.24 ± 0.36, social self-consciousness improved from 2.86 ± 1.03 to 1.33 ± 0.68, and physical difficulties improved from 2.14 ± 0.75 to 1.32 ± 0.39. Ninety-seven percent of patients thought that surgery improved how their chest looked. CONCLUSIONS. Surgical repair of pectus excavatum can significantly improve the body image difficulties and limitations on physical activity experienced by patients. These results should prompt physicians to consider the physiologic and psychological implications of pectus excavatum just as they would any other physical deformity known to have such consequences
