ABSTRACT

Appropriate size selection of double?lumen tubes (DLTs) for one?lung ventilation (OLV) in adults is still a humongous task. Several important factors are to be considered like patient height, gender, tracheal diameter, left main bronchial diameter, and cricoid cartilage transverse diameter. In addition to radiological assessment of the airway diameters, the manufacturing details of the particular DLT being used also play a significant role in size selection. Optimal positioning of the appropriately sized DLT is indispensable to avoid complications like airway trauma, cuff rupture, hypoxemia, and tube displacement. It is imperative to know whether the one?size?fits?all dictum holds for DLT size selection as claimed by certain studies. Further randomized studies are required for crystallizing standard protocols ascertaining the correct DLT size. This systematic review article highlights the various parameters employed for DLT size selection and explores the newer DLTs used for adult OLV.

ABSTRACT

Abstract Dexmedetomidine is a highly selective α-2 agonist which has recently revolutionized our anesthesia and intensive care practice. An obstetric patient presented for emergency cesarean delivery under general anesthesia, with pre-eclampsia and postpartum hemorrhage. In carefully selected cases with refractory hypertension and postpartum hemorrhage, dexmedetomidine can be used for improving overall patient outcome. It was beneficial in controlling both the blood pressure and uterine bleeding during cesarean section in our patient.


Resumo Dexmedetomidina é um α2-agonista altamente seletivo que recentemente revolucionou a nossa prática de anestesia e tratamento intensivo. Uma paciente obstétrica foi admitida para cesariana de emergência sob anestesia geral, com pré-eclâmpsia e hemorragia pós-parto. Em casos cuidadosamente selecionados com hipertensão refratária e hemorragia pós-parto, dexmedetomidina pode ser usada para melhorar o resultado geral da paciente. O fármaco foi benéfico no controle tanto da pressão arterial quanto do sangramento uterino durante cesariana em nossa paciente.
