VERSED TRAINING, cont. ONGOING ASSESSMENT: 1. General - Respiratory depression and apnea must be identified promptly with visual inspection, and careful continuous observation to allow prompt detection and appropriate intervention for emesis, hypersalivation, airway malposition, etc. 2. Pulmonary Ventilation - Sedative medications depress ventilatory drive and may decrease airway patency by relaxation of oral/pharyngeal soft tissue. Pulmonary ventilation should be monitored to provide the earliest indication of inadequate air exchange. Observation of spontaneous respiratory activity or continuous auscultation of breath sounds usually can monitor ventilatory function. 3. Oxygenation – Pulse oximetry must be used on a continuous basis to provide the earliest warning of hypoxemia. There may be a delay of a minute or more between the onset of apnea and the first decrease in oximeter reading, particularly if the patient is breathing supplemental oxygen. Therefore, pulse oximetry should never replace direct observation of the patient. 4. Hemodynamics – Sedation medications may directly depress cardiac function. In addition, they may impair the ability of the autonomic nervous system to compensate for hemodynamic changes. Monitoring of blood pressure should be monitored at frequent intervals, with continuous cardiac monitoring. 5. Level of Consciousness – Patients whose only response is to withdrawal from painful stimuli are very sedated, approaching a state of deep sedation, and special care must be taken to ensure the patency of the airway, adequacy of pulmonary ventilation, and hemodynamic stability. Deep sedation is not the desired effect in the prehospital setting. Immediate action is needed before patient may loose independent airway control and stops breathing. EQUIPMENT: Assure the following equipment is readily available prior to medication administration: 1. Continuous pulse oximetry. 2. BVM device (ambu bag with seal easy mask). 3. Cardiac monitor. 4. Non-invasive blood pressure monitor. 5. Suction equipment with assorted catheters, including yaunkers. 6. Assure age specific devices available per the ALS Standard Drug and Equipment protocol. MANAGEMENT OF COMPLICATIONS: Since it is impossible for the Paramedic to observe the amnesic effect of Midazolam, and the possibility of sedation/deep sedation exists, it is imperative to understand how to deal with these and other undesired effects. 1. Possible Allergic Reactions - Anaphylaxis, rash, hives redness, edema, wheezing, stridor, itching, edema, hypotension, syncope, respiratory distress, sneezing, apnea. See Allergic Reaction/Anaphylaxis protocol. 2. Bradycardia – Always consider a patient’s baseline heart rate when diagnosing bradycardia. Patients with ischemic heart disease are at higher risk for ventricular dysrhythmias. Bradycardia is a heart rate < 60 BPM and treatment is recommended if patient is symptomatic. See ACLS: Bradycardia. 3. Hypoventilation and hypoxemia – Small decreases in oxygen saturation correlate to large decreases in arterial oxygen levels. A decrease in oxygen saturation from pulse ox of 95% to 90% correlates to a decrease in arterial oxygenation from 80 to 60 mmHg (normal is 80-100 mmHg). Any drop in oxygen saturation needs immediate investigation. Hypoventilation occurs when the patient enters a deep state of sedation or when sedation causes a decrease in work of breathing in a patient who is in a compensated respiratory state. Obstruction of airway by secretions or foreign bodies (tongue, loose teeth, denture, or airway adjuncts). When patients’ hypoventilate, their ability to exchange oxygen and carbon dioxide decreases. Oxygen intake decreases, causing hypoxemia. Carbon dioxide exhalation decreases, causing hypercarbia. Hypoxemia causes decreased oxygen delivery to the tissues, causing tissue hypoxia. Cardiac muscle becomes irritable and likely to generate dysrhythmias and ectopic beats when hypoxic. Reduction in respiratory rate (bradypnea): 10 years to Adults, a respiratory rate of less than 10/min. Respiratory depression must be assessed and treated quickly, because of the patient’s high risk for further deterioration. Contact base hospital immediately and follow the Inadequate Oxygenation/ Ventilation algorithm. VERSED TRAINING, cont.
