Optimal Positioning of Nasopharyngeal Temperature Probes: A Prospective Cohort Study
NCT02042625 · View on ClinicalTrials.gov ↗
Study Summary
Low body temperature (hypothermia) is often observed in anesthetized patients. Mild hypothermia increases complications such as surgical blood loss, postanesthesia recovery and the duration of hospitalization. To assess body temperature and minimize hypothermia-related complications, it is important to have accurate and reliable methods of measuring intraoperative core temperature. Common practice is to insert a nasopharyngeal (back of the throat from the nose) probe through one of the nostrils. However, there is no consensus or guideline regarding how deep the nasopharyngeal probe needs to be inserted. This study is being done to determine the insertion depth (or range of depths) that best approximates core temperature, which is temperature of the vital organs, e.g. heart, liver and lungs. Participation in the trial will occur on the day of surgery. The subject will be asked to breathe through one nostril and then the other before receiving anesthesia. The less congested nostril will be selected for study. If there is no difference, then the investigator will use the right nostril. Once under anesthesia, an esophageal temperature probe will be inserted to serve as a reference core temperature, which is used routinely in surgery. Then the nasopharyngeal probe will be inserted into the nostril. Both nasopharyngeal and esophageal temperatures will initially be recorded 45 minutes after anesthetic induction. The nasopharyngeal probe will then be withdrawn 2 cm and after a 3-minute equilibration period, nasopharyngeal and esophageal temperatures will again be recorded. The nasopharyngeal probe withdrawal sequence will be repeated, 2 cm at a time, until only 2 cm remains in the nostril. There will be a total of 10 sets of nasopharyngeal and esophageal temperatures obtained.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02042625
The ClinicalTrials.gov registry entry for NCT02042625 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 36 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is The Cleveland Clinic, which has 607 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Hypothermia appearing as the primary indexed condition, and to 1 intervention — of which Nasopharyngeal is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02042625 reports 1 study location spanning 1 distinct geographic area — top geographies include Ohio. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
