Conditions: Medical and Surgical,

Registration Number: CTRI/2023/08/056107

Lead Sponsor: Baroda Medical College

Brief Summary: TITLE:

EFFICACY OF HIGH FLOW NASAL CANNULA OXYGENATION VERSUS APNOEIC OXYGENATION IN PATIENTS UNDERGOING RIGID BRONCHOSCOPY - A PROSPECTIVE RANDOMIZED CONTROL STUDY

AIMS & OBJECTIVES:

Our goal is to compare the efficacy of High Flow Nasal Cannula with other methods of apnoeic oxygenation in patients undergoing rigid bronchoscopy to provide a better mode of oxygenation and to prevent hypoxia and the adverse effects related to it.

Primary Objectives: 1. Incidence and the time to desaturate to an Spo2 <92% for more than 10 seconds Secondary Objectives: 1. Incidence of hypercarbia post procedure by monitoring EtCO2 levels 2. EtO2 levels post procedure 3. Number of interruptions during the procedure due to fall in SpO2 4. Severe complications (SpO2< 80%, systolic blood pressure <80 mmHg or vasopressor initiation)

e

MATERIALS AND METHODS:

110 patients belonging to age group between 18-60 years of both genders who are scheduled to undergo elective or emergency rigid bronchoscopy are randomised into 2 groups

GROUP H ï‚· In this group, patients will be given apnoeic oxygenation via High Flow Nasal Cannula with heated humidified oxygen at 37 degrees Celsius at an FiO2 of 100% at a flow rate of 30L/minute after the patient has been induced and bronchoscopy procedure has begun. GROUP A ï‚· In this group, patients will be given apnoeic oxygenation via the side port of bronchoscope with oxygen at an FiO2 of 100% at a flow rate of 6L/minute after the patient has been induced and bronchoscopy procedure has begun.

Patient will be premedicated before the procedure and baseline vital parameters such as blood pressure, pulse rate, peripheral oxygen saturation, EtCO2, EtO2 will be noted and both the groups will be preoxygenated using bag and mask with 100% oxygen at 10L/min for 3 minutes . Following the onset of apnoea after giving induction agents different methods of apnoeic oxygenation will be employed as mentioned above. The pulse rate , blood pressure and the peripheral oxygen saturation will be monitored throughout the procedure every minute and bag mask ventilation will be done if the SpO2 falls below 92%. once the procedure is over bag and mask ventilation is done until the patient regains spontaneous respiration and the EtCO2 and EtO2 immediately and 5, 10 mins post procedure will be noted .
