A device called a video laryngoscope is used, which has a smooth, curved, or less curved component called 'a blade' that helps the doctor gently see the voice box and guide the breathing tube safely into place during anesthesia; it is not a sharp tool blade.\n\nThere are two types of video laryngoscopes blades: a Macintosh- style blade with a gentle curve, approximately 90 degrees) and a hyperangulated blade (with a more pronounced curve).\n\nAlthough video laryngoscopes are safe and both types have been used for around 20 years, it is not known whether one type works better that the other in patients undergoing cesarean delivery under general anesthesia. Because general anesthesia is used in only a small proportion (about 5%) of all cesarean deliveries, research in this area is limited.\n\nThe main purpose of the study is to assess if a study comparing these two types of blades in the obstetric population is feasible. This is also known as a feasibility study, which aims to test the study plan and determine whether enough participants will join a larger study and accept the study procedures. The results will be used as a guide for a larger study.",[75,76,77,78,79,80,81,82,83],"Obstetric","Cesarean Birth","Airway Anesthesia","Intubation","General Anesthesia; Tracheal Intubation","Video Laryngoscopy","Obstetric Anesthesia","Obstetric Anesthesia Problems","General Anesthesia",[85,86,87,88,89,90,91,92,93,94,95],"obstetric","obstetric anesthesia","intubation","airway safety in OB patients","video laryngoscopy","cesarean delivery","general anesthesia in cesarean delivery","macintosh blade","hyperangulated blade","intubation in OB patients","general anesthesia","NOT_YET_RECRUITING","2026-06-19",{"date":99,"type":100},"2026-06-24","ACTUAL",{"date":102,"type":69},"2026-06-15",{"date":104,"type":69},"2028-06-30",{"name":5,"class":6},1]
