C-MAC D-blade video laryngoscope tied to faster nasotracheal intubation during traumatic cervical spine surgery
Patients with cervical spine instability have difficulty managing their airways because neck manipulations carry a risk of neurological impairment. It has been shown that the McCoy laryngoscope, with its distinctive design, offers superior glottic vision compared to the traditional Macintosh blade. In comparison to the McCoy laryngoscope, a recently published research assessed the effectiveness of the C-MAC-D blade in facilitating quicker tracheal intubation and improving glottic visibility in patients with cervical spine injuries.
The study included fifty individuals, aged 18 to 60, undergoing cervical spine surgery. People with a body mass index more than 24.9 kg/m2 and those with an impaired airway were not admitted. The whole population was randomly split into two groups using a random number table produced by the computer. The study used a McCoy laryngoscope for Nasal Intubation (NTI) in Group M and a C-MAC video laryngoscope for Group C. After preparing oxymetazoline hydrochloride, the nasal passage was lubricated with 2% xylocaine jelly. The NTI period was divided into three phases, with Magill forceps being utilised as required. Intubation failure was defined as a drop in SpO2 below 92% and an inability to intubate after 120 seconds or three efforts. Furthermore, measurements were taken of the heart rate, mean arterial pressure, and SpO2 just before to intubation as well as one and three minutes afterwards.
