Plain English summary of protocol

Background and study aims
This study aims to find out if using regional anesthesia during breast reconstruction surgery can lower pain levels, reduce the need for painkillers and opioids, decrease complications after surgery, and shorten hospital stays.

Who can participate?
Women aged 18 to 90 years who are scheduled for radical breast surgery (such as Skin-Sparing Mastectomy or Nipple-Sparing Mastectomy) or standard mastectomy (Modified Radical Mastectomy) with primary reconstruction using a prosthesis or expander placed beneath the pectoral muscle.

What does the study involve?
Participants will be randomly assigned to one of two groups. One group will receive the standard general anesthesia, while the other group will receive regional anesthesia. Both groups will complete a pain questionnaire before surgery and at 6 and 24 hours after surgery. The study will also record the use of painkillers and opioids, any complications within 24 hours after surgery, and the length of hospital stay.

What are the possible benefits and risks of participating?
Participants who receive regional anesthesia may experience lower pain levels after surgery. There are no additional risks compared to the usual procedure.

Where is the study run from?
University Hospital Dubrava/Klinička Bolnica Dubrava (Croatia)

When is the study starting and how long is it expected to run for?
October 2021 to June 2024

Who is funding the study?
University Hospital Dubrava/Klinička Bolnica Dubrava (Croatia)

InterventionPatients will be randomly assigned to one of two groups via blinded selection.
1. First group: Patients will undergo the standard anesthetic protocol used for general anesthesia.
2. Second group: Patients will receive regional anesthesia following this protocol:
o Thoracic paravertebral block with 0.3 mL/kg of ideal body weight of 0.5% levobupivacaine + 4 mg dexamethasone + epinephrine (1:200,000), followed by:
o Additional pectoral block comprising:
0.2 mL/kg of ideal body weight of 0.5% levobupivacaine + 4 mg dexamethasone + epinephrine (1:200,000) administered between the pectoralis major and pectoralis minor muscles.
A supplementary block between the pectoralis minor and serratus anterior muscles with 0.2 mL/kg of ideal body weight of 0.5% levobupivacaine + 2 mg dexamethasone + epinephrine (1:200,000).

For premedication, Dormicum (Midazolam) 3–5 mg intramuscularly will be administered 30 minutes before the block (administered in the ward). During block administration, 1–3 mg Dormicum will be given intravenously. During surgery, deep sedation will be achieved with Propofol at a dose of 30–70 mcg/kg per minute, along with oxygen via mask at 12 L/min.
