Common complication of sedating a patient prior to intubation Masturbate live cam chatrooms no email or sign up
The equipment and drugs for the intubation are planned, including the endotracheal tube size, the laryngoscope size, and drug dosage. Intravenous access is obtained to deliver the drugs, usually by placing one or two IV cannulae.
Newer methods of pre oxygenation include the use of a nasal cannula placed on the patient at 15 LPM at least 5 minutes prior to the administration of the sedation and paralytic drugs.This provides an oxygen reservoir in the lungs that will delay the depletion of oxygen in the absence of ventilation (after paralysis).For a healthy adult, this can lead to maintaining a blood oxygen saturation of at least 90% for up to 8 minutes."Modified" RSI refers to changes that deviates from the classic pattern, usually to reduce acidosis or improve oxygenation, but at the expense of increased regurgitation risk; examples of modifications include giving ventilations before the tube has been placed, or not using cricoid pressure.The procedure is used where general anesthesia must be induced before the patient has had time to fast long enough to empty the stomach; where the patient has a condition that makes aspiration more likely during induction of anesthesia, regardless of how long they have fasted (such as gastroesophageal reflux disease or advanced pregnancy); or where the patient has become unable to protect their own airway even before anesthesia (such as after a traumatic brain injury).Lidocaine has the ability to suppress the cough reflex which in turn may mitigate increased intracranial pressure.For this reason Lidocaine is commonly used as a pretreatment for trauma patients who are suspected of already having an increase in intracranial pressure.This minimizes insufflation of air into the patient's stomach, which might otherwise provoke regurgitation."Classic" RSI involves pre-filling the patient's lungs with a high concentration of oxygen gas, followed by applying cricoid pressure, administering rapid-onset sedative or hypnotic and neuromuscular-blocking drugs that induce prompt unconsciousness and paralysis, inserting an endotracheal tube with minimal delay, and then releasing the cricoid pressure.Patients with reactive airway disease, increased intracranial pressure, or cardiovascular disease may benefit from pretreatment.Two common medications used in the pretreatment of RSI include Lidocaine and Atropine.
