Collaborative Monitoring of Sedation Patients: A Team Responsibility

Effective dental sedation services require a well-trained team that works together to ensure patient safety. Registered dental hygienists and assistants play a critical role in this process, and it’s essential for experienced team members to regularly refresh their knowledge of monitoring responsibilities and patient safety to reduce the likelihood of errors. In addition, to ensure patient safety, high-quality monitoring equipment must be used, and team members should receive training on how to use and set alarms for the equipment.

Let’s dive into some of the key aspects of monitoring sedation patients as a team!

Conducting Thorough Pre-Sedation Appointments and Identifying Red Flags

Pre-sedation workup appointments are crucial to avoid complications during sedation. The sedation team should gather extensive information on the patient’s medication and medical history and work together to identify and address any potential management issues before sedation.

To ensure safe sedation, it’s important to identify red flags that indicate potential management issues. The dental team plays a crucial role in recognizing these warning signs and accurately completing paperwork. Examples of red flag conditions include:

• Angina: Sedation can reduce cardiac workload and increase vasodilation, making sedation for stable angina patients safer than without sedation.
• Cirrhosis: Cirrhosis limits the liver’s ability to metabolize sedation drugs.
• Advanced age: Patients over 65 require special attention due to age-related health issues such as diabetes, heart disease and high cholesterol. They may have decreased plasma proeins and therefore only require half the normal dose.
• HIV/Hepatitis: Patients don’t have to disclose HIV status; medication lists may reveal hepatic infections.
• Diabetes: Baseline blood glucose readings and recent hemoglobin A1C values should be obtained at the sedation workup visit.
• Respiratory diseases: Controlled asthmatics can receive sedation, but not COPD patients.
• Sleep apnea/BMI: Patients with high BMI, OSA, large neck circumferences, and Mallampati scores of III to IV require special attention.
• Polypharmacy: Medications increase the risk of drug interactions. Always check for potential interactions with a reliable resource.
• Myocardial Infarction/Coronary Stents: Patients who had a heart attack, stent placement, or cardiac surgery should wait six months before dental work.
• Date of last physical exam: Patients should have seen a physician for medical evaluation based on guidelines that consider age and health.
• Pregnancy: Sedation during pregnancy is only acceptable in life-threatening emergencies.

Invest in Quality Monitoring Equipment

Dental offices must invest in high-quality monitoring systems that record vital signs every five minutes. For example, the Edan X is a hospital-grade monitor that can print and digitally record heart rate, end-tidal CO2, pulse oximetry and three lead heart rhythms.

Monitor Heart Rate and Blood Pressure

Monitoring a patient’s heart rate and blood pressure is essential, especially for patients anxious about dental care. Elevated pulse rates can indicate the need for sedative drugs or dosage adjustments, and those with low blood pressure may experience light-headedness. This can lead to reduced blood flow to vital organs. Establishing a baseline blood pressure can help identify abnormal changes in blood pressure and aid in providing safe sedation.

Monitor Blood Oxygen Levels

Maintaining proper blood oxygenation levels is crucial during conscious sedation. While cardiac events are rare, most emergencies occur due to respiratory issues resulting in low blood oxygen. Pulse oximeters can alert teams to abnormal levels; however, a thorough physical exam is necessary to assess cardiovascular health and limit the risk of poor oxygenation. Further, low oxygenation may indicate underlying respiratory issues, and it is essential to ensure that the patient’s oxygen levels remain within normal limits during the procedure.

End-tidal CO2 Monitoring

Measuring exhaled carbon dioxide, or end-tidal CO2, is crucial in monitoring ventilation and metabolic processes. Capnography, which produces a waveform on the monitor, allows for real-time measurement.

Recognizing Abnormal Heart Rhythms

While it takes years for cardiologists to learn all the different heart rhythms, team members need to recognize what a normal heart rhythm looks like to identify abnormal ones.

Monitor for Signs of Low Blood Sugar

Patients with hypoglycemia or diabetes require extra attention during procedures, even without sedation. Monitor for signs of low blood sugar and conduct a thorough health history.

Reviewing your Sedation Dentistry Team Annually

Regular team training is crucial for patient safety. In addition, comprehensive reviews of responsibilities and protocols are necessary to meet industry safety standards and dental regulations and to boost team confidence.

Efficient dental sedation teams train every person in the office, as monitoring sedation patients is a collective effort. Maintaining consciousness, detecting red flags, and using high-quality monitoring devices are crucial to patient safety.
