RESUMO
INTRODUCTION: A nutritional assessment is a critical but often neglected aspect of a preoperative evaluation. Malnutrition is clearly associated with worse surgical outcomes in adults undergoing major abdominal surgery, whereas a paucity of evidence is available in the pediatric population. OBJECTIVE: The objectives were to describe the preoperative nutritional status of pediatric and adolescent patients undergoing continent urinary tract reconstruction and to determine the association among malnutrition, use of total parenteral nutrition (TPN), and surgical outcomes. STUDY DESIGN: A retrospective cohort study was performed for patients aged up to 20 years who underwent continent urinary tract reconstruction between January 2012 and November 2016. Malnutrition was classified with body mass index and height for age z-scores on admission as well as change in z-scores and weight over the 3-6 months before surgery. Primary outcomes included the duration of intensive care and hospitalization as well as readmissions and complications within 30 days. RESULTS: A total of 123 patients who underwent 130 continent urinary tract reconstructions were identified during the study period. Demographic and perioperative data are provided in the Table. Anthropometric and biochemical measurements as well as the early initiation of TPN (≤2 days) were not associated with any primary outcomes. In a subgroup analysis of patients with a bowel anastomosis, the early initiation of TPN was an independent predictor for duration of hospitalization (P < 0.0001) and 30-day complications (odds ratio 9.51, P = 0.005) after adjusting for other statistically significant and clinically relevant variables. DISCUSSION: The few available studies on surgical nutrition have primarily focused on infants and young children undergoing cardiac surgery and provided no consensus on a preoperative nutritional assessment. The findings on TPN from the present study favorably compare with a growing body of evidence in adult and pediatric critically ill and surgical patients. The limitations of the present study include its retrospective design at a single institution, potential misclassification of nutritional status, and selection bias from the initiation of TPN at the discretion of the primary surgeon. CONCLUSIONS: Malnutrition was identified in greater than 20% of pediatric and adolescent patients undergoing continent urinary tract reconstruction. Anthropometric and biochemical parameters were not associated with surgical outcomes, although the early initiation of TPN did not offer any benefit for nutritional support. In a subset of patients with a bowel anastomosis, TPN was associated with worse surgical outcomes, including a longer duration of hospitalization and development of 30-day complications.

Increased intra-abdominal pressure is a complication of thermal injuries that is most commonly noted during burn shock or sepsis. Severely elevated intra-abdominal pressure requires surgical treatment by laparotomy to avert cardiac, respiratory, and renal compromise. The purpose of this retrospective study was to examine the manipulation of the nutrition program and outcomes in response to such a procedure. Open laparotomy for increased intra-abdominal pressure was necessary for 6 patients admitted to a pediatric burn facility from March 1993 to April 1999. One patient was excluded from the review because he died 2 days after the burn injury (1 day after the laparotomy) and nutrition intervention was not initiated. Four of the five remaining patients received parenteral nutrition within 48 hours of surgery. One patient did not receive parenteral nutrition because the enteral regimen was at the goal by 5 days after the laparotomy. Trophic enteral feedings were initiated in all 5 patients within 48 hours of the operations. Tube feedings were gradually increased and the parenteral nutrition rate was decreased in accordance with gastrointestinal tolerance (abdominal girth, bowel motility). Enteral nutrition was started before abdomen closure in all of the patients. No mechanical, infectious, or mortality-related complications related to the initiation of enteral nutrition after open laparotomies were noted. Surgical intervention by open laparotomy interrupts the postburn nutrition regimen but does not preclude the safe postoperative delivery and advancement of enteral feedings.

The present study was undertaken to find if pregnant women's smoking habits were related to the presence of meconium in the amniotic fluid. The medical records of 58 women admitted to the OB service between January 1, 1992, and December 31, 1992, were reviewed. Data from the records was analyzed. Findings indicated that smoking was not related to the presence of meconium in the amniotic fluid. Some women who did not smoke had meconium stained amniotic fluid. Some women who smoked had no meconium staining. A relationship between meconium staining and maternal smoking habits was not supported.

A 10-year-old, 36-kg child with a malignant air leak who failed conventional mechanical ventilation and high-frequency jet ventilation was successfully treated with a neonatal high-frequency oscillatory ventilator for 31 days. Since the air leak resolved with minimal hemodynamic compromise, this technique may have application in the management of respiratory failure and air leak in the older and larger child for prolonged periods of time.
