简要总结
Incidence of difficult laryngoscopy and difficult intubation are higher among patients with obstructive sleep apnoea (OSA). Precision in making the diagnosis and predicting difficult laryngoscopy preoperatively may help to reduce anesthetic complications. This study was designed to evaluate the diagnostic performance of combined and non-combined radiological parameter (mandibulohyoid distance) and STOP-BANG questionnaire as screening tool.
.
Methodology:
Forty-one subjects who were at risk of OSA, undergoing general anaesthesia will be included using STOP-BANG questionnaire. Mandibulohyoid distance and other radiological parameters will be measured from lateral cephalometry. Evaluation for difficult laryngoscopy will be carried out during anaesthesia.
详细描述
RESEARCH DESIGN:Cross sectional study
STUDY HYPOTHESES: There is a significant correlation between STOP-BANG score and cephalometric measurement with difficult intubation in patients at risk of Obstructive Sleep Apnoea.
Null hypothesis:
There is no significant correlation between STOP-BANG score and cephalometric measurement with difficult intubation in patients at risk of Obstructive Sleep Apnoea.
SAMPLE SIZE ESTIMATION This is a cross sectional study with 2 means. For objective 1, sample size calculation is done using power and sample size program version 3.1.2
