Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was done to compare the ease of tracheal intubation using the conventional C blade and the D blade of CMAC videolaryngoscope in patients undergoing cervical spine surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Manual in-line stabilisation is used to immobilise the neck during endotracheal intubation in patients undergoing cervical spine surgery to prevent secondary spinal cord damage. This makes visualisation of the glottis difficult with conventional laryngoscopy which can be overcome with videolaryngoscope. CMAC Videolaryngoscope has the conventional blade (C blade) and the highly angulated D blade which was introduced to aid in difficult airway. This study was done to compare the ease of tracheal intubation using the conventional C blade and the D blade of CMAC videolaryngoscope in patients undergoing cervical spine surgery.

Methodology: After Institutional Ethics Committee approval and obtaining informed consent, 68 patients undergoing elective cervical spine surgery were randomised into 2 groups - C (intubated with C blade) or D (intubated with D blade) (n=34 each) by computer generated randomisation. After induction of general anaesthesia, manual in-line stabilisation of the cervical spine was achieved and intubation was attempted by experienced anaesthesiologist with the C blade or D blade according to the group. The time taken for successful intubation, time taken for optimum glottic visualisation, the number of attempts, additional manouvres required for successful intubation and the incidence of complications were compared.
