The auditory evoked potential in premature small for gestational age infants / 소아과

PURPOSE: This study aimed to evaluate the usefulness of auditory evoked potential (AEP) in clarifying neuronal development in premature small for gestational age (SGA), and appropriate for gestational age (AGA) infants. METHODS: A total of 183 premature infants who were born from August 2002 to July 2005, were examined with AEP. They were divided into three groups; AGA, symmetric-SGA and asymmetric-SGA group. RESULTS: Statistically significant differences in the head circumference were observed in three groups. Among the risk factors, prevalence of hypoglycemia and hypoalbuminemia between AGA and asymmetric SGA infants were significantly different. V absolute peak latency (APL) in the right side of AGA infants was delayed were than that of asymmetric SGA infants. III-V interpeak latency (IPL) of asymmetric SGA infants was delayed more than that of symmetric SGA infants. Moreover, I-V IPL on both sides of symmetric SGA infants was shortened more than that of AGA infants. However, all the results of AEP were within the reference range, according to gestational age. Birth weight of, only asymmetric SGA, was related to the III APL on both sides and the III-V IPL on right side. CONCLUSION: This study shows that the values of APL and IPL of premature SGA infants are different than that of premature AGA infants. These data could be an indicator in evaluating the neurologic functions of small for gestational age infants.

Primary peritoneal drainage as a treatment for perforated necrotizing enterocolitis with bacterial peritonitis in an extremely low birth weight infant: a case report / 소아과

Necrotizing enterocolitis(NEC) is the most common life-threatening surgical emergency in neonates, and remains a major cause of morbidity and mortality. In addition to conventional laparotomy, intraperitoneal drains have been used for the treatment of perforated NEC, especially in extremely low birth weight(ELBW) infants. We report a case of perforated NEC with bacterial peritonitis in an ELBW infant managed with primary peritoneal drainage(PD) without further need for surgery. To our knowledge, this is the first documented Korean case of an ELBW infant where PD was used as primary treatment for perforated NEC. Primary PD is effective and safe in ELBW infants with perforated NEC; although it is not considered a definitive procedure, it should be considered in all cases where infants are too unstable to tolerate anesthesia and surgery.

Usefulness of modified ambu(R) in patients who need artificial ventilation / 소아과

PURPOSE: The comatose mentality can be catastrophic, especially if the condition is severe or the duration is prolonged. Therefore, delayed diagnosis can result in a poor outcome or death. The best radiologic modality to differentiate from cerebral lesions in patients suffering from cerebral diseases is magnetic resonance imaging (MRI) rather than computed tomography (CT). Special apparatuses with metal materials such as ventilators, and cardiac pacemakers belonging to patients cannot be located in the magnetic field. We aimed to exhibit the possibility of examining MRI, maintaining ventilation at a relative long distance by means of modified Ambu(R). METHODS: Self-inflating bags as a sort of a manual ventilator, connected with relatively long extension tubes instead of mechanical ventilators, were adopted to obtain MRI. PVC (polyvinyl chloride) extension tubes had different lengths and diameters. Lengths were 1, 2, and 3 cm and diameters were 15, and 25 mm. The work of breathing and expiratory changes of expiratory tidal volume (TVe), minute volume of expiration (MVe), peak inspiratory pressure (PIP) were measured by use of the mechanical ventilator, Servoi(R), as the alteration of TVi (inspiratory tidal volume), extension tube lengths and diameters with other values fixed. RESULTS: Measured TVe and MVe by ventilator were the same values with control at every TVi, regardless of extension tube lengths and diameters, but PIP were increased with the rise of TVi, tube lengths, with decline of tube diameters, these were statistically significant. CONCLUSION: MRI examination can be carried out with a self-inflating bag connected with an extension tube at a long distance in patients who need artificial ventilation.

Lateral Thoracic Expansion Surgery for Jeune's Syndrome / 대한흉부외과학회지

Jeune's asphyxiating thoracic dystrophy is a rare, complex malformation with a broad spectrum of clinical expression. The degree of chest wall deformity is the most important prognostic factor and the only part which is correctable. A 11 month-old male infant was diagnosed as having Jeune's syndrome and received right side lateral thoracic expansion surgery. But because respiratory distress symptom was sustained postoperatively, we performed left side procedure 3 months after the initial operation. Respiratory distress symptom got worse after fracturing the left titanium plate which was inserted to fix the expanded thoracic wall and reimplantation was performed. The patient was discharged 6 months after the initial operation. He was readmitted and received ventilator care for respiratory failure and died 10 months after the initial operation.
