Vasopressor use following traumatic injury - A single center retrospective study

Objectives

Vasopressors are not recommended by current trauma guidelines, but recent reports indicate that they are commonly used. We aimed to describe the early hemodynamic management of trauma patients outside densely populated urban centers.

Methods

We conducted a single-center retrospective cohort study in a Canadian regional trauma center. All adult patients treated for traumatic injury in 2013 who died within 24 hours of admission or were transferred to the intensive care unit were included. A systolic blood pressure <90 mmHg, a mean arterial pressure <60 mmHg, the use of vasopressors or ≥2 L of intravenous fluids defined hemodynamic instability. Main outcome measures were use of intravenous fluids and vasopressors prior to surgical or endovascular management.

Results

Of 111 eligible patients, 63 met our criteria for hemodynamic instability. Of these, 60 (95%) had sustained blunt injury and 22 (35%) had concomitant severe traumatic brain injury. The subgroup of patients referred from a primary or secondary hospital (20 of 63, 32%) had significantly longer transport times (243 vs. 61 min, p<0.01). Vasopressors, used in 26 patients (41%), were independently associated with severe traumatic brain injury (odds ratio 10.2, 95% CI 2.7–38.5).

Conclusions

In this cohort, most trauma patients had suffered multiple blunt injuries. Patients were likely to receive vasopressors during the early phase of trauma care, particularly if they exhibited signs of neurologic injury. While these results may be context-specific, determining the risk-benefit trade-offs of fluid resuscitation, vasopressors and permissive hypotension in specific patients subgroups constitutes a priority for trauma research going forwards.

Lengthening technique for long gap esophageal atresia and early anastomosis

BACKGROUND/PURPOSE

The treatment of long gap esophageal atresia remains a major surgical challenge. Whereas many approaches have been used for this problem, none are ideal. The authors used a technique originally described by Dr John E. Foker and accomplished early repair in 3 infants with long gap atresia.

METHODS

Three infants with esophageal atresia underwent thoracotomy shortly after birth and had a long gap preventing primary anastomosis. External traction sutures were placed on each esophageal pouch and exteriorized through the thoracic wall. The esophageal ends were approximated 1 to 2 mm daily by traction on the sutures. Anastomosis was performed when the 2 ends came together.

RESULTS

Three infants were included (31, 34, 37 weeks gestation, weights 1.38 kg, 1.9 kg, and 2.3 kg, respectively). The esophageal gaps were 3, 5, and 4.5 cm, respectively. Definitive anastomosis was performed at 14, 17, and 10 days, respectively. Two patients had anastomotic leaks that were treated conservatively. One patient had an esophageal stenosis that required dilatation.

CONCLUSIONS

This technique allowed rapid esophageal lengthening in these 3 cases and led to early repair of long gap esophageal atresia, avoiding the need for a prolonged hospitalization or eventual replacement as well as long-term swallowing difficulties.

Childhood adrenocortical tumors: case series and reevaluation of prognosis--a 24-year experience

Adrenocortical neoplasms are rare in childhood and adolescence. The prognostic significance of tumor size, weight, and histological grade are still very much unclear. Eleven patients, (3 boys, 8 girls), with a median presentation age of 7 years (range, 0.8 to 16 years) were identified. Six presented with virilizing symptoms, two with cushingoid symptoms, one with both, and two others had nonspecific symptoms. The interval between onset of symptoms and diagnosis was an average of 18 months (median, 8 months). Hormonal profile correlated well with clinical presentation in nine patients. Two patients with nonspecific symptoms had an aldosterone-producing lesion and an androgen-secreting tumor. Ten patients underwent complete surgical excision, with one intraoperative spillage. Median tumor weight was 94.5 g (range, 4 to 750 g). Three lesions were less than 5 cm in maximal width, six were between 5 and 10 cm, and two were greater than 10 cm. Two tumors had capsular or vascular invasion. Three patients received chemotherapy: one who had inoperable metastatic disease, and two based on clinical and histopathologic findings. Ten patients are doing well, without evidence of recurrent disease with a median follow-up of 3 years (range, 9 months to 15 years), eight patients have been followed up for more than 2 years. The medically treated patient who had metastatic disease died 3 years after diagnosis. A review of the pediatric literature, in some cases, indicates that larger tumors have a worse prognosis, while other investigators claim histological grade is more important. The authors' results do not support these conclusions, but rather suggest that in the pediatric population, when excision is complete, guarded optimism is warranted even with tumors larger than 5 cm. Addendum: Since submission of the manuscript, patient 4 has been operated on twice for local recurrences 13 and 16 months after the initial surgery. She was the only patient in the series to have an intraoperative capsular tear. All other surgical patients remain free of disease.

Intrahepatic biliary-enteric bypass for complete extrahepatic biliary obstruction in children

Intrahepatic biliary-enteric anastomosis is rarely practiced in pediatric surgery. The authors report on two children who have been successfully treated using this method. First described by Longmire and Sandford in 1948, intrahepatic biliary-enteric anastomosis is possible in children. This procedure is only indicated as a last recourse for circumstances in which the extrahepatic biliary tree is completely obstructed.
