Transnasal Humidified Rapid Insufflation Ventilatory Exchange in Laryngotracheal Resection and Reconstruction: A Report of Two Pregnant Cases.

Introduction: The incidence of tracheal stenosis is progressively increasing. A risk factor for developing this clinical condition is a history of prolonged endotracheal intubation. A transnasal humidified rapid insufflation ventilatory exchange, known as THRIVE, has gained importance in tracheal resection surgeries. Case Presentation: Herein, we describe the anesthetic management of two obstetric patients, a 19-year-old and 29-year-old, with a history of prolonged endotracheal intubation and a diagnosis of tracheal stenosis. The patients required the resection of the tracheal segment and end-to-end anastomosis. The anesthetic management focused on THRIVE using a high-flow nasal cannula. Conclusions: This system proved to be a safe anesthetic technique for pregnant women and the fetus. Furthermore, it allowed surgeons to better visualize the surgical field without the risk of accidental injury to the endotracheal tube.

Safety of neuraxial anesthesia in patients twin pregnancy and twin-to-twin transfusion syndrome taken to laser photocoagulation. Retrospective cohort study / Seguridad de la anestesia neuroaxial en mujeres con embarazo gemelar y síndrome de transfusión feto-fetal, sometidas a fotocoagulación láser. Estudio de cohorte retrospectiva

Objective: To describe the clinical characteristics and the frequency of maternal, fetal and neonatal complications in accordance with the neuraxial anesthesia (NA) technique in women with twin-totwin transfusion syndrome (TTTS) treated with laser photocoagulation. Materials and Methods: Descriptive retrospective cohort study of pregnant patients with TTTS treated with laser photocoagulation under NA at Fundación Valle del Lili, Cali (Colombia), between 2013-2017. Patients with Quintero stage V TTTS were excluded. The protocol was approved by the institutional ethics committee. Results: Of the participants, 32 met the inclusion and exclusion criteria. The study population consisted of young, multiparous women. Urgent interventions were performed in 87.5% of cases; 43.7% were Quintero stage III and epidural anesthesia was used in 56.2% of the women. Maternal hemodynamic variables were similar, in accordance with the timing of surgery and the neuraxial technique used. Sustained hypotension occurred in 65.6% of the pregnant women and 9.3% developed pulmonary edema. Pre-term delivery occurred in 65.6% of the patients and 18.7% had premature rupture of membranes. There were 14 fetal demises and five neonatal deaths. There were no cases of maternal mortality. Conclusions: In patients with TTTS requiring laser photocoagulation, the use of epidural, spinal or combined anesthesia is likely associated with similar maternal hemodynamic variables at the time of surgery. Practitioners providing care to these pregnant women must be aware of the frequent occurrence of maternal, fetal and neonatal complications. Prospective studies to assess the safety and effectiveness of the different neuraxial anesthesia techniques in patients with TTTS are required.

Objetivo: describir las características clínicas y la frecuencia de complicaciones maternas, fetales y neonatales, según técnica de anestesia neuroaxial (AN) en mujeres con síndrome de transfusión feto-fetal (STFF) tratadas con fotocoagulación láser (FL). Materiales y métodos: estudio de cohorte retrospectiva descriptivo. Se incluyeron gestantes con STFF tratadas con FL y AN en la Fundación Valle del Lili, Cali (Colombia) entre 2013-2017. Se excluyeron pacientes con STFF estadio-V de Quintero. Se usó estadística descriptiva. El protocolo fue aprobado por el Comité de Ética de la institución. Resultados: 32 participantes cumplieron con los criterios de inclusión y de exclusión. La población estuvo constituida por mujeres jóvenes, multíparas. En el 87,5% de los casos se realizó intervención de urgencia. El 43,7% presentaba el estadio-III de Quintero y en el 56,2 % de las gestantes se utilizó anestesia epidural. Las variables hemodinámicas maternas exhibieron un comportamiento similar, acorde al momento de la cirugía y la técnica neuoraxial implementada. El 65,6 % de las gestantes presentó hipotensión sostenida y el 9,3 % desarrolló edema pulmonar. El 65,6 % de las pacientes experimentó parto pretérmino y el 18,7 % ruptura prematura de membranas. Se registraron 14 muertes fetales y cinco neonatales. No se registraron casos de mortalidad materna. Conclusiones: en pacientes con STFF que requieren FL, el uso de la anestesia epidural, espinal o combinada probablemente se asocia con un comportamiento similar al de las variables hemodinámicas maternas, durante los momentos de la cirugía. Los profesionales que brindan atención a estas gestantes deben estar alerta ante la frecuente aparición de complicaciones maternas, fetales y neonatales. Se requieren estudios prospectivos que evalúen la seguridad y la efectividad de las diferentes técnicas de anestesia neuroaxial en pacientes con STFF.

Quadrupled Semitendinosus ACL Reconstruction Combining Cortical Button in Femur and Interference Screw in Tibia.

Anterior cruciate ligament (ACL) reconstruction with hamstring tendons has gained popularity in the past and is the most used type of graft in several national registries. It usually involves the harvest of both gracilis and semitendinosus tendons from the ipsilateral knee. More recently, the use of only 1 of the tendons (semitendinosus) in a tripled or quadrupled arrangement has been described, especially in an all-inside type of reconstruction. Having a thicker tendon with a quadrupled semitendinosus (ST), instead of double gracilis and ST enables to a have a graft with enough diameter to resemble more closely the native ACL and decreases the risk of graft rerupture. This Technical Note aims to present a way of reconstructing the ACL using a quadrupled ST graft, with suspensory cortical button in femur and interference screw in tibia, as an alternative to the all-inside technique.
