Study to compare time taken to intubate with Videolaryngoscopy versus Conventional laryngoscopy in adult patients undergoing Surgery under General Anesthesia- Prospective randomized study at SMS medical college and attached group of hospital, Jaipur

Direct laryngoscopy is most widely used method of oro-tracheal intubation but at times it could be difficult, and may lead to adverse effect on cardiovascular system. Video laryngoscopy in contrast provides better visualization of airway making oro-tracheal intubation easy. In this study we will compare the use of Video laryngoscope (Group A) versus the macintosh (direct) laryngoscope blade (Group B) for routine airway management. 88 ASA grade 1 and grade 2 patients between the age of 18 and 60 yrs scheduled for elective laparoscopic cholecystectomy surgery will be included in the study. Informed written consent will be taken in the vernacular language. Premedication with injection (Inj) glycopyrolate 0.2 mg intravenous(i.v) 10 mins before + Inj. midazolam 0.02mg/kg i.v. 10 mins and (inj) metoclopramide 10mg i.v. 10mins before  + injection fentanyl 2mcg/kg i.v. will be given. All the patients will be preoxygenated with 100% oxygen through a face mask for three minutes, then general anesthesia will be induced with intravenous administration of inj. propofol (2 mg/kg), and inj Succinylcholine (2 mg/kg) Then patients will be randomly divided into 2 groups. Group  A (n=44) will be intubated using video laryngoscope (indirect) and Group B (n=44) will be intubated using direct laryngoscope (Macintosh) In the group A, an intubating stylet will be used. The oro-tracheal intubation will be carried out. Time taken for tracheal intubation procedure, visualization of airway, Haemodynamic parameters (Systolic BP, diastolic BP, mean arterial pressure, heart rate) will be assessed at numerous intervals as follow: baseline, after induction of anesthesia, one and five minutes after intubation.
