Anesthetic concerns for pediatric neurosurgery are multifold and become more challenging with syndromic children like in Edward syndrome (Trisomy 18), which include airway problems (micrognathia), congenital heart disease, craniofacial anomalies, visceral abnormalities, and mental retardation. A 4-day old, preterm neonate weighing 1.39 kg, was posted for emergency repair of leaking meningomyelocele. There was difficulty in suckling and feeding since birth. Antenatal maternal ultrasound revealed hydrocephalus, ventriculomegaly, and disorganized lumber and sacral vertebre. On physical examination, he had a lumbar meningomyelocele which was leaking since birth, along with skeletal dysplasia, micrognathia with proximal shortening of lower limbs, and bilateral “Rocker bottom foot.” Pre-operative vital parameters were: heart rate - 131/min, respiratory rate - 48/min, blood pressure -57/31 mmHg, Spo2 - 97% on room air, blood sugar (random) - 94 mg/dL, on blood gas analysis pH was 7.28, pCo2 - 41.3 mmHg, po2 - 40.32 mmHg. All other laboratory investigations were within normal limits. Cardiac 2-D echocardiogram revealed that he had a 4 mm of ostium secundum atrial septal defect (ASD) and 2 mm of patent ductus arteriosus (PDA) with mild tricuspid regurgitation (TR). On ultrasound examination of the cranium, there was gross dilatation of third and fourth ventricles. A diagnosis of Edward syndrome was made by the pediatric team.
After thorough pre-anesthetic evaluation, the child was shifted to a pre-warmed operating room. Precordial stethoscope was placed along with standard ASA monitoring and difficult airway cart was kept ready. For temperature monitoring, we placed temperature probe in axillary region. Following preoxygenation, modified rapid sequence induction was performed using 1.5 mcg/kg of fentanyl, etomidate 0.3 mg/kg, and 0.6 mg/kg rocuronium IV. A 3.5 mm uncuffed endotracheal tube was inserted and oral packing was done [Figure 1]. Anesthesia was maintained with sevoflurane + air + oxygen mixture. After intubation, cannulation of right femoral vein and right radial artery were done under strict aseptic precautions. Patient was made prone with adequate padding. Hypothermia prevention methods like warm intravenous fluids, forced air warmer, and covering of exposed body parts were used. Anesthestic considerations for congenital heart disease with left to right shunt were followed, including keeping all the lines free of air bubbles and stabilizing hemodynamics (maintenance of systemic vascular resistance (SVR), peripheral vascular resistance (PVR) and heart rate). The entire perioperative period was uneventful. Postoperatively, oral pack was removed and the neonate was shifted to NICU (neonatal intensive care unit) intubated for elective ventilation and monitoring in view of preoperative and intraoperative ABG findings (acidosis). The neonate was extubated the next day with normal vital parameters. He was later referred to cardiology/cardiac surgery department for definitive management of congenital heart disease.
Edward syndrome is the second most common autosomal trisomy after down syndrome. It consists of congenital heart disease, craniofacial anomalies, muscular hypotonia, mental retardation, and extremity deformities. Congenital heart disease can present in the form of atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA). There is a need for thorough pre-anesthesia planning in a case of child with Edwards syndrome with multiple defects in order to prevent any drastic hemodynamic changes. There is also the possibility of difficult airway because of micrognathia. There is concern regarding patient positioning to prevent rupture of meningomyelocele sac. Few previous reports show that succinylcholine should be avoided in cases of Edward syndrome, because it may cause muscle rigidity. Hence, we used Rocuronium in place of succinylcholine. There is dearth of the literature available for the anesthesia management of a child with Edward syndrome with multiple systemic defects.
