Hemodynamic Changes of Tracheal Intubation With McCoy and Macintosh Laryngoscopes
Condition: Hemodynamic Rebound
Study type: Interventional

Summary: 
      A total of 272 patients were randomly allocated into two groups, Patients in group A were
      treated with Macintosh laryngoscope and in groups B with McCoy laryngoscope was used for
      endotracheal intubation. Pulse and systolic blood pressure was recorded by non-invasive
      measures before laryngoscopy and at 30 seconds, 2 and 3minutes after intubation. All this
      information was recorded on a Pro forma.
    

Detailed description: 
      After taking approval from hospital ethical committee, 272 patients who reported to Operation
      Theatre of CMH, Jhelum were selected for the study. Informed consent was obtained and patient
      demographic information (name, age, contact) was recorded. Patients were randomly divided in
      two equal groups by using lottery method. GROUP A: Where Macintosh laryngoscope was used for
      endotracheal intubation. GROUP B: Where McCoy laryngoscope was used for endotracheal
      intubation.

      Before reporting to Operation theatre a detailed pre anesthesia assessment was done in all
      patients, all necessary laboratory investigations were collected. On OT table pulse and
      systolic blood pressure was checked by non-invasive method. 18G cannula was passed and ECG
      was attached. A pillow was placed under the head to obtain classical sniffing position for
      intubation. All the patients were pre medicated with injection midazolam 0.08mg/kg, injection
      nalbuphine 0.1 mg/kg, injection dexamethasone 0.08mg/kg and injection metoclopramide 0.1
      mg/kg. Pre oxygenation was done with 100% oxygen for 3 mins. Induction was done with
      injection propofol2 mg/kg, muscle relaxation achieved with injection atracurium 0.5mg/kg.
      Laryngoscopy was started after 3 minutes by a qualified anesthetist. Pulse and systolic blood
      pressure was recorded by non-invasive measures before laryngoscopy and at 30 seconds, 2 and
      3minutes after intubation. All this information was recorded on a Proforma.
