RESUMO

PURPOSE: Oxygen delivery through a Frova Intubating Introducer may be life-saving, and gas flow characteristics through this device have been described. Nevertheless, the feasibility of using a self-inflating resuscitation bag to deliver air or oxygen through this device has not been assessed. We compared volumes of air delivered and peak pressures generated with normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer. METHODS: In this bench research study, the proximal end of the 14-F Frova Intubating Introducer was connected to the self-inflating resuscitation bag, and the distal end was connected to a flow analyzer fitted with an adult test lung. Thirty-five anesthesia health care providers (staff/trainees) squeezed the self-inflating resuscitation bag with three normal and three maximal bimanual compressions. Endpoints of interest included the delivered volume of air and generated peak pressure. RESULTS: Normal bimanual compression resulted in a smaller mean (standard deviation) volume of air and peak pressure compared with maximal bimanual compression [554 (131) vs 955 mL (121); mean difference - 400.4; 95% confidence interval [CI], - 441.8 to - 359.0; P < 0.001; and 22.0 (3.4) vs 41.8 cmH2O (13.3); mean difference - 19.7; 95% CI, - 23.5 to - 15.9; P < 0.001, respectively]. CONCLUSION: Clinically useful, life-sustaining volumes of air can be delivered using normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer.

RéSUMé: OBJECTIF: L'administration d'oxygène au travers d'un introducteur (bougie) Frova pour intubation peut sauver une vie et les caractéristiques du débit de gaz à travers ce dispositif ont été décrites précédemment. Néanmoins, la faisabilité de l'utilisation d'un ballon de réanimation pour administrer de l'air ou de l'oxygène à travers ce dispositif n'a pas été évaluée. Nous avons comparé des volumes d'air délivrés et les pressions maximales générées avec une compression bimanuelle normale ou maximale d'un ballon de réanimation autogonflant relié à un introducteur Frova pour intubation de 70 cm. MéTHODES: Dans cette étude expérimentale, l'extrémité proximale de l'introducteur Frova 14F pour intubation a été connectée au ballon de réanimation autogonflant et son extrémité distale a été connectée à un analyseur de débit adapté à un poumon adulte artificiel. Trente-cinq prestataires d'anesthésie (patrons/résidents) ont comprimé le ballon de réanimation avec trois compressions bimanuelles normales et trois compressions maximum. Les critères d'évaluation ont inclus le volume d'air délivré et la pression maximum générée. RéSULTATS: La compression bimanuelle normale a fourni un volume d'air moyen (ET) et une pression maximum moyenne (ET) inférieurs à la compression bimanuelle maximum (554 [131] contre 955 mL [121]; différence des moyennes, -400,4; intervalle de confiance [IC] à 95 % : ­441,8 à − 359,0; P < 0,001; et 22,0 [3,4] contre 41,8 cmH2O [13,3]; différence des moyennes, ­19,7; IC à 95 % : − 23,5 à − 15,9; P < 0,001). CONCLUSION: Des volumes d'air cliniquement utiles pour le maintien en vie peuvent être administrés par compression bimanuelle normale et maximum d'un ballon de réanimation autogonflant connecté à un introducteur Frova pour réanimation de 70 cm.

RESUMO

BACKGROUND: Polydactyly is the most common malformation of the limbs. "Crossed" polydactyly of hands and feet, i.e., preaxial in one and postaxial in the other, is extremely rare. It has not been included in the standard classification of hand and feet anomalies. METHODS: We report an Indian family with 7 affected members across 4 generations who had "crossed polysyndactyly". All but one affected member had involvement of all four limbs. There were no other congenital anomalies in any of the family members. RESULTS: Familial crossed polysyndactyly appeared to follow an autosomal dominant transmission. This is probably the first case of familial crossed polysyndactyly without any associated anomalies. CONCLUSION: Familial crossed polysyndactyly is a rare malformation and all family members should be screened for other congenital malformations.
