The purpose of this study is to determine whether sedation with a combination of pethidin hydrochlorid plus midazolam intravenously (i.v.) is superior to propofol i.v. alone in relation to blood pressure drops during an transesophageal echocardiographic examination (TEE).
Drug: pethidin hydrochlorid, midazolam
Intervention Model: Single Group Assignment
Masking: Single Blind (Subject)
||Phase II Study of Comparison of Two Sedation Regimen for Transesophageal Echocardiography in Point of View of Blood Pressure Response, Safety and Patient Comfort
Primary Outcome Measures:
- Number of patients with a blood pressure drop of more than 30 mmHg and below 100 mmHg systolic [ Time Frame: During examination (TEE), expected to be ca. 30 minutes ]
Secondary Outcome Measures:
- Number of patients with adverse events [ Time Frame: At time of transfer to the ward, expected to be after ca. 1 hour ]

Active Comparator: Pethidin plus midazolam
Initial dose of 25 mg Pethidin iv. plus 1-2 mg Midazolam iv. Additional Bolus of Midazolam (1 mg wise iv.) if needed, until a maximal dose of 7 mg Midazolam iv.
50 years and over: initial dose of 50-60 mg Propofol iv. Followed by bolus of 20-30 mg iv. until sedation is achieved.
< 50 years: initial dose 30-40 mg Propofol iv. Followed by bolus of 10-20 mg until sedation is achieved.
Other Name: Propofol = Propofolum = Diprivan = Disoprivan
Active Comparator: Propofol
Initial dose of Propofol of 50-60 mg iv. for patients 50 years or younger. Initial dose of Propofol of 30-40 mg iv. for patients over 50 years. If needed additional Bolus of 20-30 mg Propofol iv. as usual until sedation is achieved.
Drug: pethidin hydrochlorid, midazolam
Pethidin hydrochlorid: 25 mg iv. at the beginning of the examination Midazolam: 1-2 mg iv. at the beginning of the examination. Repetitive given in a dosis of 1 mg iv. until a total amount of 7 mg iv.
- Pethidin hydrochlorid = Meperidine (USA)
- Midazolam = Dormicum
Randomisation is done immediately after information of the patient and obtaining of the informed consent. The average time for a TEE study is about 30 minutes. Data collection occurs during this time frame. ECG monitoring and data collection (blood pressure, heart rate, SO2) for the study protocol starts 6 minutes before the application of the sedation. At -6, -4, -2 minutes before the application of the sedation, baseline data are collected. The average systolic blood pressure of these three measures is taken as the reference blood pressure. This is the reference value to calculate the blood pressure drop during the examination. Blood pressure, pulse oxymetry, heart rate are taken every 2 minutes until the examination (TEE) is finished. The questionnaire (for second end points) is filled out by the patient within two hours after the examination. The patient will be followed for the duration of about one hour after the examination, if he is from the outpatient clinic. Patients from the hospital (inpatients) will be followed routinely in the clinic.
