The goal of this prospective observational study is to learn about improvement of laryngoscopic view by Bed-Up-Head-Elevated (BUHE) during tracheal intubation in paediatric patients. The main question it aims to answer is:

1. Does BUHE position improve laryngoscopic view during paediatric intubation?

Participants age 3-12 year-old going for elective surgery under general anaesthesia requiring tracheal intubation will undergo laryngoscopic twice, first in sniffing position (SP) and second during BUHE position.

POGO score during each laryngoscope will be compared. Additionally, ease of handling of laryngoscope during each position will be assessed.

This is a prospective observational study comparing POGO score during tracheal intubation in SP and BUHE position in paediatric patients aged 3 to 12 years who will undergo elective surgery under general anaesthesia requiring tracheal intubation. The first POGO score will be obtained during SP followed by second POGO score during BUHE position and the difference in POGO score before and after BUHE position will be recorded to learn the improvement in POGO score during BUHE position.

The objective of this study is to learn the improvement of laryngeal view in tracheal intubation after BUHE position in paediatric patients of age 3 to 12 years. Investigators hypothesised that laryngeal view in tracheal intubation improves after BUHE position compared to sniffing position.
