Brief Summary: Securing the airway is very essential during general anesthesia procedure. There are many laryngoscopic blade for the same. In our study we will compare a newer videolaryngoscopic blade- Hugemed videolaryngoscopic blade with Maccoy and the conventional Machintosh blade. Hence there will be three groups with 50 patients in each group. After obtaining the informed consent, we will conduct the study in patients posted for surgery under general anesthesia needing endotracheal intubation meeting the other inclusion criteria as mentioned. Computer based randomised will be done. We will try to simulate the difficult airway by using the rigid cervical collar which will restrict the neck extension , just before the intubation. We will use premedications , inducing agent propofol and vecuronium as mescle relaxants. Anesthesia will be maintained by nitrous oxide and volatile agents. intubation will be attempted by trained anesthesiologist. When intubation is attempted depending on the group, the intubation difficulty score as described by Adnet et al. and time taken for intubation will be noted as our primary objective states. We will also note the difficulty in laryngoscopic blade insertion and any complications as our secondary objective states. data will be collected in preformed proforma. Blinding of the participant and data analyser can be done. But blinding of the investigator will be difficult to be maintained.

Further the patient will be monitored throughout the surgery and reversed and then extubated. Any adverse effect or complications during this period will be noticed. Statistical data will be analysed using SPSS software 28.
