Brief Summary

Obstructive Sleep Apnea (OSA) is the most common problem that affects sleep. People with this problem have their airway blocked or minimized, causing snoring or gasping while sleeping. It can also reduce the amount of oxygen that circulates in the blood of people affected by it. Millions of Americans have OSA; 10% of adults have diagnosed OSA, an estimated 25% have undiagnosed OSA. There is concern in the medical community about how to manage pain in patients with OSA because of the risk of decreased or slower breathing associated with certain pain medications called opioids. Giving OSA patients opioids could cause them to have even lower oxygen amounts in their blood stream. It is conceivable that patients with OSA may require lower doses of opioids to cause decreased breathing as compared to patients without OSA, however this has not been proven. In this study, we are using a very short acting and easily reversible opioid pain medication called remifentanil in patients with OSA in order to find out if treated and untreated OSA patients respond to opioid differently than patients without OSA.

Outcome Measures

Primary Outcomes (1)

  • The relationship between remifentanil concentration and miotic effect

    Baseline, 10, 20, 30, 40, and 50 minutes for each concentration

Study Arms (3)

targeted infusion of remifentanil untreated OSA

EXPERIMENTAL

Stepped-dose, targeted infusion of remifentanil with measurement of miosis, respiratory rate, end-expired CO2, and thermal analgesia and plasma drug concentrations. Remifentanil dose will be based on ideal body weight.

Drug: Targeted infusion of remifentanil

targeted infusion of remifentanil CPAP treated OSA

EXPERIMENTAL

Stepped-dose, targeted infusion of remifentanil with measurement of miosis, respiratory rate, end-expired CO2, and thermal analgesia and plasma drug concentrations. Remifentanil dose will be based on ideal body weight.

Drug: Targeted infusion of remifentanil

targeted infusion of remifentanil No OSA

EXPERIMENTAL

Stepped-dose, targeted infusion of remifentanil with measurement of miosis, respiratory rate, end-expired CO2, and thermal analgesia and plasma drug concentrations. Remifentanil dose will be based on ideal body weight.

Drug: Targeted infusion of remifentanil

Interventions

Remifentanil dosing will be calculated using ideal body weight and infused to achieve brain concentrations of 0.5, 1, 2, 3, and 4 ng/ml; approximately 10 minutes at each concentration.
