General information about the trial
|
|||
Main objective of the trial |
to find out if dexamethason added to modified pectoral block (Pecs II) with ropivacaine 0.2% prolongs analgesic effect
|
||
Protection of trial subjects |
The visual analogue scale (VAS) to assess pain was assessed on admission to the post-anesthesia care unit (PACU), then hourly during the first 12 hours after PECS II block performance, and then every 12 hours until the end of follow-up after 84 hours. If VAS exceeded a value of 30 mm at any time, even without being actively asked by the medical staff, pain medications according to our study protocol were administered.
Generally spoken - every patient who needs a mastectomy receives a PECS II block - if not refused by the patient. For this study we didn't change the daily routine, neither in the operating theatre nor on the normal ward.

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
10 Nov 2018 |
We found out that our patients are being followed-up by the gynecologists every 3 months for approximately 1 year, so we decided that we design a questionnaire to ask for patient satisfaction and pain. By extending the observation period, we had to make a substantial amendment. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
None reported | |||
