3 Stridor musical, monophonic, audible breath sounds (noisy breathing) caused by oscillations of narrowed large extrathoracic airwaysindicates a partial obstruction of the upper airways, glottis, or trachea
4 History CC : inspiratory stridor 1 day after birth PI : Maternal Hx. : 24 yr. G1P0A0Antenartal Hx : Adequate ANCGA 40 wks by dateC/S due to CPD
5 Term AGA female infantBW 3630 g (P75), HC 34 cm (P50), Lt 51 cm (P 50)Apgar 7 (color 2, RR1), 9 (RR1)O2 tubing 5 LPM and tactile stimulationAfter birth RR 48/min30 min after birth developed tachypnea and gruntingTransfer to nursery
6 At nursery: physical examination V/S : T 37.6 C, P 163/min, BP 61/36 mmHg, RR 52/minSp O2 65% (RA)GA : Active, central and peripheral cyanosis, no jaundice, no hemangioma at beard and neck regionHEENT : no midline defect, poor nasal airflow Rt. > Lt.
7 At nursery: physical examination RS : Dyspnea, subcostal retraction,no flaring of alar nasi, no grunting, normal breath sounds, no adventitious sound,no stridorCVS : Normal S1,S2, no murmurAbdomen : WNLNS : Normotonia, symmetrical movement, grasping reflex +ve, rooting reflex +ve, Moro reflex +ve

9 Cyanosis developed when she received spoon feeding and spontaneously recovered, then she was retained OG tube.Cyanosis and inspiratory stridor related with hoarse crying can be improved by prone position.
23 Congenital Vocal cord paralysis Unilateral-stridor and retraction are not markedweak & hoarse cry, aggravated by agitationFeeding difficulties
24 Congenital Unilateral Vocal cord paralysis Etiologyusually idiopathicsecondary to peripheral n. esp. recurrent laryngeal n.-Lt.sided : commonperhaps from birth trauma-Rt. Sided : complication of thoracic & neck surgeryMay be lesions in the mediastinum(tumors and vascular malformations)Prognosis – uncertain due to etiologies
25 Congenital Vocal cord paralysis Bilateral -much more serious conditionstridor at restnear-normal phonationprogressive airway obstructionpoor prognosis due to underlying and associated problems
26 Management in this patient SpecificNo specific treatment for vocal cord paralysisIx for underlying etiologySupportiveObserve respiratory: apnea, SpO2Retain OG tubeCorrect position
28 Take home messageUpper airway obstruction can be cured as conservative but when the patient develop - cyanosis when feeding- weak cry- hoarseness of voice- abnormal lat. neck film- biphasic stridorREFER
