Expect the Unexpected
Neonatal Oral Mass Diagnosed at Birth

Anesthesiology May 2013

A full-term, 3.5-kg neonate was transferred for management of a large, mobile intraoral mass. The infant demonstrated no signs of airway obstruction or respiratory  distress and had normal oxygen saturation without support. The child did not seem dysmorphic and the mass was isolated  to the anterior maxillary alveolar ridge, easily mobilized out of mouth. A prenatal ultrasound at 20 weeks did not identify any anomalies. Adequate ventilation was achieved after mobilizing the mass extraorally and achieving adequate mask seal. At this point, a mask induction with spontaneous ventilation was performed, followed by uneventful intubation. The mass was considered low risk for airway obstruction during induction  because it did not disturb the airway anatomy, and was easily mobilized out of the mouth. Epulis, or congential granular cell tumor, is a rare tumor of variable size and number originating from gingival epithelial tissue seen in newborn infants, affecting female infants 8:1, and is rarely malignant.


Differential diagnosis for neonatal oral masses includes teratoma, hemangioma, lymphatic malformation, or congenital malformation or neoplasm.
 When diagnosed prenatally, consideration for airway obstruction  at birth may require intervention upon delivery. However, prenatal diagnosis is not always achieved. Considerations before induction of anesthesia focus on the anatomic location of the mass, distortion or obstruction of the airway, and signs of airway obstruction. Although computed tomography or magnetic resonance imaging studies may yield information about airway involvement, the infant may require an airway intervention before or during the study.

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body

Steroids In Perioperative period...The Multi-purpose Drugs

1-Steroids are not Bronchodilator ,but have well established usefulness in hyper-reactive airway. They are also said to have a permissive role for bronchodilator medication. They can be administered orally, parenterally or in aerosol form 2- Steroids have been commonly used in chemotherapy for prevention of nausea along with other anti-emetic agents . Dexamethasone was found to be highly effective when given immediately before induction rather than at the end of anesthesia . 3- Steroids do exert analgesic effects. Various routes of administration of steroids include parentral, local infiltration at operated site , as an adjuvant in nerve blocks and central-neuraxial blockade. 4 - Steroids cannot be the mainstay of therapy in anaphylaxis because of the delayed onset of action, so they are used as adjunct after initial treatment with epinephrine. 5- Steroids (Dexamethsone) are of value in reduction or prevention of cerebral edema associated with parasitic infections and neopla...
