Challenges of airway management in a patient with temporomandibular joint ankylosis complicating forceps delivery: a case report / Retos en el tratamiento de las vías respiratorias en una paciente con anquilosis de la articulación temporomandibular complicando el parto con fórceps: reporte de un caso

Ankylosis of the temporomandibular joint following forceps delivery is a rare anomaly. The aetiopathogenesis involves wrongful application of the forceps or forceful closure of the forceps handle against the condyle with haemathrosis, organisation and subsequent ankylosis. Because of the lack of epidemiological data, there is little information about the true incidence and the management of this rare anomaly. The purpose ofthis presentation is to report the challenges encountered in the airway management of a six-year old female with right temporomandibular joint ankylosis following forceps delivery in a private hospital setting.

La anquilosis de la articulacion temporomandibular tras el uso de forceps siguientes es una rara anomalia. La etiopatogenesis implica la aplicacion indebida de los forceps o el cierre forzoso del mango de los forceps contra el condilo con hemartrosis, organizacion y subsiguiente anquilosis. Debido a lafalta de datos epidemiologicos, hay poca informacion acerca de la verdadera incidencia y el tratamiento de esta rara anomalia. El objetivo de esta presentacion es informar los problemas encontrados en el tratamiento de las vias respiratorias de una niha de seis ahos con anquilosis de la articulacion temporomandibular derecha tras de un parto con forceps en el contexto de un hospital privado.

Mecanismos patogénicos de la parálisis braquial congénita: [revisión] / Pathogenic mechanisms of congenital brachial palsy: [review]

Antecedentes: Se define clásicamente a la parálisis braquial congénita como la paresia flácida de una extremidad superior secundaria al estiramiento traumático del plexo braquial durante el parto, en la extracción del hombro anterior, en relación a la distocia de hombro. Numerosas series han reportado la falta de relación entre la parálisis braquial congénita y el estiramiento traumático del plexo braquial durante la distocia de hombro. Objetivo: Realizar una revisión de la literatura para identificar las causas relacionadas con la parálisis braquial congénita. Resultados: Hasta en un 50 por ciento de los casos la parálisis braquial congénita no se asocia a distocia de hombro. Estos casos, son de peor pronóstico, afectan principalmente al hombro posterior y se presentan en recién nacidos de menor peso al nacer, pudiendo presentarse en un parto cesárea. La parálisis braquial congénita no asociada a distocia de hombro reconoce múltiples mecanismos patogénicos como: postura viciosa fetal in útero, tracción del hombro posterior por el promontorio sacro, neoplasias fetales, tumores uterinos, y otras. Conclusión: La parálisis braquial congénita, debe ser entendida como un síndrome, clínicamente caracterizado por parálisis flácida de una de las extremidades superiores detectada en el recién nacido, que responde a diferentes mecanismos patogénicos y de pronóstico variable según el caso.

Background: Classically congenital brachial palsy was defined as a flaccid paresis of the upper limb, secondary to traumatic brachial plexus stretching during delivery of the anterior shoulder in the context of shoulder dystocia. Numerous series have reported the lack of relationship between congenital brachial palsy and traumatic stretching of the brachial plexus during shoulder dystocia, in a significant number of cases. Objective: To review the literature to identify the causes related to congenital brachial palsy. Results: Up to 50 percent of cases of congenital brachial palsy are not associated to shoulder dystocia. These cases, have worse prognosis, mainly affect the posterior shoulder, presents in infants of lower birth weight and may even be in a cesarean delivery. Congenital brachial palsy not associated with shoulder dystocia recognizes multiple pathogenic mechanisms such as: vicious fetal position in utero, traction of the posterior shoulder on the sacral promontory, fetal tumors, uterine tumors, and others. Conclusion: Congenital brachial palsy, should be understood as a syndrome, clinically characterized by flaccid paresis/paralysis of one upper limb detected in the newborn, being the consequence of different pathogenic mechanisms and having variable prognosis.

Forceps or vacuum extraction: a comparison of maternal and neonatal morbidity

To compare maternal and neonatal morbidity associated with forceps and vacuum delivery, data on 150 women delivered by forceps and 420 delivered by vacuum extraction between 1995 and 1999 at Queen Alia Hospital, Jordan were compared. Data included parity, gestational age, infant birthweight, Apgar score, presentation and station of fetal head, indications for forceps and vacuum deliveries, delivery success rate, and maternal and neonatal morbidity. Maternal birth canal and genital tract lacerations were significantly more common in forceps delivery, and there was significantly increased morbidity in infants delivered by vacuum extraction [caput, jaundice, cephalohaematoma]. Serious neonatal morbidity was rare for both groups

Neonatal and maternal complications among pregnant women delivered by vacuum extraction or forceps extraction.

A historical cohort study was used to analyse the maternal and neonatal complications among pregnant women delivered by vacuum or forceps extraction at Rajavithi Hospital, 1994. The maternal complications (third and fourth degree of perineal tear and postpartum hemorrhage) were statistically significant more often in the forceps group than in the vacuum extraction group. But fetal complications (neonatal hyperbilirubinemia, low Apgar scores (< 7) at 1 and 5 minutes and the transfer to NICU) were statistically significant more often in the vacuum extraction group than in the forceps group.

Espátulas de Thierry: maniobra de rotación con rama invertida en posiciones occipito posteriores de la cabeza fetal / Thierry's spatula: rotational manipulation with inverted lever in occipito posterior position of fetal head

La maniobra de rotación con rama invertida de Esátula de Thierry (ET) (1, 2) es descrita y se presentan los resultados en una serie de 54 aplicaciones en pacientes que en el momento del expulsivo presentaban una distocia de posición cefálica posterior persistente. No hubo mortalidad materna ni fetal
