Sustained Neuromuscular Blockade after Vecuronium Use in a Premature Infant.

Background Prolonged use of neuromuscular blocking agents (NMBAs) is very common in critically ill children both in pediatric and neonatal intensive care units. There are no guidelines available for use of NMBAs in children or neonates in the US, and the data for their safety in this age group is limited. Case Description Our case describes prolonged neuromuscular blockade following concurrent use of a NMBA along with aminoglycosides and steroids in the setting of renal failure in a premature infant. Conclusion Prolonged use of NMBAs in preterm infants should be avoided if possible or should be restricted to the shortest possible duration and the smallest possible physiologically effective dose. Concurrent use of NMBAs with aminoglycoside and steroids should be avoided, especially in the setting of renal failure.

Crew resource management improved perception of patient safety in the operating room.

To improve safety in the operating theater, a company of aviation pilots was employed to guide implementation of preprocedural briefings. A 5-point Likert scale survey that assessed the attitudes of operating room personnel toward patient safety was distributed before and 6 months following implementation of the briefings. Using Mann-Whitney analysis, the survey showed a significant (P < .05) improvement in 2 questions (of 13) involving reporting error and 2 questions (of 11) involving patient safety climate. When analyzed by occupation, there were no significant changes for faculty physicians; for resident physicians, there was a significant improvement in 1 question (of 13) regarding error reporting. For nurses, there were significant improvements in 3 questions (of 4) involving teamwork, 1 question (of 13) involving reporting error, and 3 questions (of 11) regarding patient safety climate. These results suggest that aviation-based crew resource management initiatives lead to an improved perception of patient safety, which was largely demonstrated by nursing personnel.

Symptomatic persistent sciatic artery in a newborn.

Persistent sciatic artery is an unusual anatomical anomaly first noted in 1832. Approximately 60 to 70 cases have been documented in the literature, but none described symptomatic persistent sciatic artery presenting in the neonate. We report a case of a newborn infant who presented after birth with an atrophic right lower extremity and ischemia. Ultrasound with Doppler and magnetic resonance angiography revealed a right persistent sciatic artery with hypoplastic external iliac artery. The common femoral artery was reconstituted above the bifurcation into the superficial femoral and profunda femoral artery via collaterals from the internal iliac and the persistent sciatic artery. The infant's blood flow to the right extremity gradually improved for the next 4 days without treatment and continues to have adequate blood flow.

Are routine cranial ultrasounds necessary in premature infants greater than 30 weeks gestation?

The purpose of this study was to validate the recommendation of the American Academy of Neurology and the Child Neurology Society that screening cranial ultrasonography be performed routinely on all infants of less than 30 weeks gestation at 7 to 14 days of age and again between 36 and 40 weeks postmenstrual age, and, by using this practice parameter, to determine the number of babies with a clinically significant abnormal screening cranial ultrasound (US) who would otherwise have been missed. A retrospective study of 486 infants of 30 to 33 weeks gestation born January 1, 1999 to June 30, 2004 was done. All had screening cranial ultrasounds. Grade III and/or grade IV intraventricular hemorrhage (IVH) occurred in 4 (0.8%) infants of 30 to 31 weeks gestation. Infants with significant IVH had either risk factors for brain injury or symptoms that would eventually warrant US during their hospitalization. Seven (1.4%) infants had periventricular leukomalacia (PVL). All infants with a final diagnosis of PVL had pre- and/or perinatal risk factors associated with PVL. There was a significant trend toward fewer abnormal cranial ultrasounds from 30 to 33 weeks gestation (p=0.04). Our study supports the recommendation by the American Academy of Neurology and the Child Neurology Society that screening US can be limited but suggests that the gestational age cut off should be 30 weeks or less.

Outcome of gastroschisis: a 20-year case review of infants with gastroschisis born in Galveston, Texas.

BACKGROUND/PURPOSE: In the past decade, the preferred method of closure of gastroschisis at our institution has been staged reduction using a silo with repair on an elective basis (SR) rather than primary surgical closure (PC). We performed a 20-year case review of infants with gastroschisis at a university hospital to compare these shifts in management and to determine factors affecting outcome. METHODS: Seventy-two cases were reviewed from 1983 to 2003. Times to first and full feeds were outcome variables for statistical analysis. RESULTS: The prevalence of gastroschisis increased from 0.03% to 0.1% since 1983. Patients had low birth weights (mean = 2294 g) and were borderline premature (mean = 35.8 weeks). Only 3% of the infants were African American. There was a high rate of cesarean deliveries (57%). Ten patients (15%) had gastroschisis complicated by liver herniation, intestinal atresia(s), and/or necrosis/perforation. Most patients were managed by SR (67%). Eight percent of the infants died, 9% developed necrotizing enterocolitis, and 50% had other gastrointestinal complications. Twenty-seven percent of the infants managed with SR did not need initial mechanical ventilation. However, the patients who underwent SR were ventilated longer after birth as compared with those who underwent PC (P < .08). Infants with a complicated gastroschisis had significantly longer times to first and full feeds (P < .001). Patients managed with SR took significantly longer to reach full feeds (P = .001), and there was a trend of starting feeds later (P = .06). When patients with a complicated gastroschisis were excluded, the differences between the SR and PC groups were even greater (P = .01; P < .001). CONCLUSIONS: In our patient population, the prevalence of gastroschisis increased by more than 400% since 1983. The defect was rare in African-American infants. Management by SR was associated with longer ventilation times and longer times to first and full feeds for both uncomplicated and complicated gastroschisis cases.

Gardnerella vaginalis-infected scalp hematoma associated with electronic fetal monitoring.

Infections in the neonate caused by the vaginal commensal Gardnerella vaginalis are rare and mostly consist of bacteremia. A 4130-g term neonate developed an infection of a scalp hematoma with G. vaginalis. The infection developed in association with electronic fetal monitoring. The only clinical sign was an increase in size of the hematoma.
