Anesthetic management of tracheoesophageal fistula repair in a newborn with hypoplastic left heart syndrome

Let us save the brain with cerebral oximeter: Two case reports

In the neonates, tracheal atresia and tracheoesophageal fistula (TEF) surgery may result in hemodynamic instabilization, leading to cerebral perfusion insufficiency due to the retraction of the pulmonary vessels and truncus brachiocephalicus. We represented one male and one female neonates which were performed thoracoscopic primary repair of TEF through right thoracotomy at the 3^th and 4^th postpartum day. Anesthesia was induced using sodium thiopental (5 mg/kg), fentanyl 4 mcg, and rocuronium (0.5 mg/kg) given through intravenous route. Sevoflurane 2% and 50% O₂in air were used for the maintenance therapy. During the right lung compression to expose posterior esophagus, no value was observed on the pulse oximeter (PO) probe placed on the right hand, and radial artery was not palpated. At the same time, oxygen saturation was observed as 96%-97% on the left foot probe. As the right cerebral oximeter values (rSO₂) were rapidly decreased to 31%, the lung compression was ceased. Right pulse oximeter and right rSO₂measurements return to the baseline levels. For the second case - different from the first case -both left and right rSO₂was rapidly decreased to 40% levels and return to the baseline levels after was removed the retractors. Right PO and right and left cerebral rSO₂values returned to baseline immediately when the retractor compression was ended During the operations involving the great vessels in neonates, cerebral perfusion could be preserved using cerebral oximeter. Cerebral oximeter is more efficient than pulse oximeter for detecting cerebral tissue oxygenation and could be helpful to minimize neuronal damage in the neonates.

Emergency laparotomy for necrotising enterocolitis in a newborn with hypoplastic left heart syndrome

Necrotising enterocolitis (NEC) and congenital heart disease are two distinct disease processes, but they appear to be inter-related, particularly in patients with the congenital heart condition known as hypoplastic left heart syndrome (HLHS). Both NEC and HLHS are causes of significant morbidity and mortality in the neonatal population. As medical and surgical advances allow for the palliation and correction of complex heart lesions at an earlier gestational age and lower birth weight, the already high-risk of NEC in this population is likely to increase. In this article, we report a case of a neonate with unpalliated HLHS who underwent emergency laparotomy for NEC. We also discuss the pathophysiology of these two diseases and the perioperative care of this rare group of patients.

Anesthetic management of tracheoesophageal fistula repair in a newborn with a double-outlet right ventricle

A case of a newborn with a double-outlet right ventricle and tracheoesophageal fistula is presented. The pathophysiology of double-outlet right ventricle and its anesthetic implications for tracheoesophageal fistula repair are discussed.

Anesthetic management of congenital tracheoesophageal fistula

This article reviews (a) risk factors and preoperative considerations of the patient with tracheoesophageal fistula, (b) anesthetic management, including (i) airway management, (ii) induction of anesthesia and monitoring and (iii) postoperative disposition, (c) considerations for concomitant congenital heart disease, (d) considerations for thoracoscopic repair and (e) long-term outcomes and considerations of the patient with repaired esophageal atresia/tracheoesophageal fistula.

Anesthesia for major general surgery in neonates with complex cardiac defects

Centers with large cardiac workloads may be presented with neonates who need major general surgery before correction or palliation of a serious cardiac defect. This is still a rare situation with only three short case reports available in the medical literature (1-3). We have reviewed the anesthetic and analgesic regimens of 18 such neonates who presented to the Birmingham Children's Hospital in the 4-year period 2004-2007. These children require meticulous preoperative evaluation and although it might be anticipated that they would pose a serious challenge to anesthetists, in reality with thorough investigation, preparation, and careful management, they tolerate general anesthesia well. These children may be transferred to centers of specialist pediatric cardiac anesthesia to be benefited from experience obtained there.
