Fuga gaseosa persistente posoperatoria / Posoperative Persistent Gas Leak

Introducción: La fuga gaseosa persistente es la complicación posoperatoria más frecuente en cirugía torácica. En la actualidad no hay estudios con suficiente evidencia científica que permitan establecer una norma para el tratamiento de esta complicación. Objetivo: Ofrecer una actualización de los factores predisponentes de la fuga gaseosa, así como las modalidades de tratamiento que han surgido en los últimos años. Métodos: Se realizó una revisión bibliográfica en bases de datos MEDLINE (PubMed), SciELO, así como Google académico. Se tuvieron en cuenta variables como tipo de resección pulmonar, tiempo quirúrgico, complicaciones posoperatorias, se emplearon las palabras claves en idioma español e inglés y se seleccionaron un total de 44 artículos publicados desde el 1998 hasta el 2020. Desarrollo: Aunque por lo general esta complicación se considera leve, puede llegar a tener una incidencia de un 46 por ciento, asociándose a un aumento en la estadía hospitalaria, con repercusión en el costo sanitario, así como incomodidad y morbilidad para el paciente. En dependencia del momento en que se presente y su localización el tratamiento incluirá diferentes alternativas que abarcan desde la conducta conservadora, hasta diferentes modalidades de pleurodesis, tratamiento endoscópico o quirúrgico. Conclusiones: La resolución de esta entidad se produce en la mayoría de los pacientes mediante el empleo de sonda pleural, mientras que en el resto se requerirán estrategias alternativas, siendo importante el conocimiento por parte de los cirujanos de su forma de prevención, así como de todas las opciones terapéuticas, para su adecuado empleo en base a su criterio o experiencia(AU)

Introduction: Persistent gas leak is the most common postoperative complication in thoracic surgery. Currently there are no studies with sufficient scientific evidence to establish a standard for the treatment of this complication. Objective: To offer an update of the predisposing factors of gas leak, as well as the treatment modalities that have emerged in recent years. Methods: A bibliographic review was carried out in MEDLINE (PubMed), SciELO databases, as well as in academic Google. Variables such as type of lung resection, surgical time, and postoperative complications were taken into account. The keywords in Spanish and English were used and a total of 44 articles published from 1998 to 2020 were selected. Discussion: Although this complication is generally considered mild, it can have 46 percent incidence, being associated with an extra time of the hospital stay, affecting health costs, as well as discomfort and morbidity for the patient. Depending on when it occurs and its location, the treatment will include different alternatives that range from conservative management, to different modalities of pleurodesis, endoscopic or surgical treatment. Conclusions: The resolution of this entity occurs in most patients through the use of a chest tube, while alternative strategies will be required for the rest. It is important for surgeons to know their form of prevention, as well as all the therapeutic options, for their proper use based on their criteria or experience(AU)

Interruption in the supply of breathing gas during general anesthesia due to malposition of the vaporizer: A case report / 대한마취과학회지

We report a case of interruption in the supply of breathing gas during general anesthesia caused by malposition of the Drager Vapor 2000(R) vaporizer, which was accidentally tilted and lifted off the Selectatec manifold of the anesthesia machine. Because the patient was an 1-month-old infant, we couldn't check if he had experienced awareness with recall. We emphasize the importance of checking the anesthetic vaporizer after mounting it on the back bar of the anesthesia machine.

Chlorine gas leak: A school incident in Andhra Pradesh.

A gas leak occurred affecting the teaching staff as well as 65 students of a school in Andhra Pradesh, of whom 9 became seriously ill. The students were shifted to the nearest hospital. Many were treated on an out-patient basis, while 9 students were admitted for 2 days, and then discharged. Since the parents were still apprehensive about long-term sequelae arising from the exposure, the district collector directed the district medical and health officer to investigate and take necessary steps. The latter arranged a medical camp involving several medical officers under the guidance of a team of clinical toxicologists and community medical care specialists from a major teaching hospital of the area. Detailed examination and investigations were done, and all the cases were followed up. None went into long-term complications

An Unexpected Vapor Leakage from Unlocked Vaporizer (Penlon Sigma Delta Anesthetic Vaporizer): A case report / 대한마취과학회지

We present a case of an anesthetic gas leak through the valve of the Selectatec back bar during a surgical procedure. The Selectatec Vaporizing System is a quick-change system consisting of anesthetic vaporizers of the 'Tec models' of the Ohmeda machine that are seated on a compatibility manifold block located on the back bar of the anesthetic machine. In order to prevent a leak and a failure of vapor delivery, the "Tec models series" can only be turned 'on' when the locking lever is turned to the 'lock' position. However in this case, the control knob was rotated despite the back bar locking mechanism not being engaged, and a gas leak developed through the unlocked valves in Selectatec back bar. The Penlon Sigma Delta Anesthetic Vaporizer (sevoflurane) in a Datex-Ohmeda Aestiva/5 anesthesia machine can be turned 'on' when the locking lever is maintained at the 'unlock' position.
