Intubation of the GI bleeder
OVERVIEW
Massive GI hemorrhage presents multiple challenges during intubation:
- haemorrhage obscures view of vocal cords
- high risk of aspiration
- risk of haemorrhagic shock and haemodynamic instability
- risk to staff from contact with body fluids
RSI MODIFICATIONS
- wear PPE including goggles, mask, gown and gloves
- empty the stomach
— place an NGT, this does not decrease the esophageal sphincter opening pressure
— consider delayed sequence intubation if this is not tolerated
— varices are not a contra-indication
— administer prokinetics (e.g. metoclopramide 10mg IV, erythromycin 250mg IV) - perform intubation with the patient in head up 45 degrees position (Semi-Fowler position)
— optimal position for intubation success
— may decrease aspiration risk - ensure adequate preoxygenation and apneic oxygenation
— use high flow nasal prongs if available— avoid NIV in the actively vomiting patient
— consider delayed sequence intubation
— use gentle BVM to maintain oxygenation as required (e.g. 6-10 breaths/min) - Use appropriate intubation medications
— use a haemodynamically stable dose of induction agent (e.g. ketamine 1-2 mg/kg IV)
— use paralytics (e.g. rocuronium 1.2mg/kg IV); these do not drop lower esophageal sphincter tone - Use optimal equipment
— video laryngoscopes may be obscured by blood and vomit
— use 2 suction set-ups, assistants either side can hold in the corners of the patient’s mouth
— bougie
— LMA (e.g. proseal)
— meconium aspirator (can attach to ETT tube and suction as you go) - Aspiration
— aspiration pneumonitis does not need antibiotics— bronchodilators and lung protective ventilation may help
— SIRS response may require ongoing fluid resuscitation +/- pressures
