The management of postoperative pain is a challenge for the surgical team. Treatment, which usually consists of intravenous or oral opioids, is sometimes ineffective, and it is also important to remember that opioids are not free of side effects, such as nausea and vomiting, which can lead to suture dehiscence and bruising.<a class="elsevierStyleCrossRef" href="#bib0215"><span class="elsevierStyleSup">1</span></a> In addition, manipulation of the pectoral muscle during retropectoral prosthesis insertion can cause painful muscle spasms. Alternative pain management methods based on afferent nerve blocks have recently been described in breast surgery, although their efficacy in retropectoral breast augmentation has not been demonstrated.<a class="elsevierStyleCrossRef" href="#bib0220"><span class="elsevierStyleSup">2</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The innervation of the breast is complex, being supplied by multiple nerve branches.<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">3</span></a> The deep fascia on which the mammary gland lies, a space known as the retromammary bursa or Chassaignac's bursa,<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">3</span></a> receives afferents from the lateral and medial pectoral nerves, which supply motor innervation to the pectoral muscles. These motor nerves supply sensory innervation to the aforementioned fascia.<a class="elsevierStyleCrossRefs" href="#bib0230"><span class="elsevierStyleSup">4,5</span></a> The cutaneous innervation of the breast is mainly derived from the lateral and anterior branches of the 2nd to 6th intercostal nerves. The 4th intercostal nerve, which innervates the nipple, is of particular interest.<a class="elsevierStyleCrossRefs" href="#bib0240"><span class="elsevierStyleSup">6–9</span></a> The anterior branch of the intercostal nerves gives bilateral innervation, that is, right-sided branches cross over the sternum to the left and vice versa.

Exclusion criteria were: patients with known allergies to any of the medications administered, patients receiving opioid therapy, or patients in whom the infraaerolar surgical approach was changed to prepectoral prosthesis placement, or patients wishing to withdraw from the study.</p><p id="par0035" class="elsevierStylePara elsevierViewall">We performed a controlled, randomised, triple blind study. Patients were randomised on the day of inclusion in the study. Randomisation was performed by the secretary of the anaesthesiology department using the free online software Randomiser (<a id="intr0010" class="elsevierStyleInterRef" href="http://www.randomizer.org/">http://www.randomizer.org</a>).<a class="elsevierStyleCrossRef" href="#bib0275"><span class="elsevierStyleSup">13</span></a> The randomised patient list was sent to the pharmacy service, where the drug syringes were prepared and delivered to the operating room for administration on the day of the procedure. The research anaesthetist was blinded to the contents of the syringe, and the pharmacy service was not involved in any other way with the patients or the research team until the end of the study. Therefore, the patients, the anaesthesiologist and the personnel responsible for postoperative care were blinded to the patient's study group. Fifteen patients underwent modified pectoral block plus serratus plane block with local anaesthetic (treatment group [GPEC]) and in 15 other patients the same procedure was performed using saline (control group [GC]), according to the randomisation protocol.</p><p id="par0040" class="elsevierStylePara elsevierViewall">All patients underwent standardised general anaesthesia and basic monitoring. The patients were placed in the supine position and operated on using the same surgical technique by 2 surgeons with more than 15 years of experience working together. All underwent breast augmentation using the infraaerolar approach. After monitoring was started (heart rate [HR], non-invasive blood pressure [NIBP], partial oxygen saturation [SpO<span class="elsevierStyleInf">2</span>], end-tidal carbon dioxide [ETCO<span class="elsevierStyleInf">2</span>] and bispectral index [BIS]), the patients received intravenous prophylactic multimodal analgesia with paracetamol 1<span class="elsevierStyleHsp" style=""></span>g and metamizol 2<span class="elsevierStyleHsp" style=""></span>g, and 4<span class="elsevierStyleHsp" style=""></span>mg dexamethasone prophylaxis for postoperative nausea and vomiting. Following this, general anaesthesia was induced with intravenous fentanyl (1<span class="elsevierStyleHsp" style=""></span>mg/kg) and propofol (2<span class="elsevierStyleHsp" style=""></span>mg/kg). When BIS fell to below 60, an appropriately sized laryngeal mask airway (based on patient weight) was inserted.

Ultrasound was performed on both sides of the anterior thoracic wall to identify the pectoralis major and minor muscles and the thoracoacromial artery in the interfascial space, and the costal margin on both sides was counted.

An anatomical study<a class="elsevierStyleCrossRef" href="#bib0365"><span class="elsevierStyleSup">31</span></a> demonstrated the spread of the anaesthetic when injected under the muscle, showing that it reaches the lateral cutaneous branches of the intercostal nerves.</p><p id="par0170" class="elsevierStylePara elsevierViewall">We assume that analgesia was incomplete in our patients, since the anaesthetic does not reach some parts of the breast, especially the 2 medial quadrants.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">10</span></a> Blanco et al.<a class="elsevierStyleCrossRef" href="#bib0265"><span class="elsevierStyleSup">11</span></a> described the use of this block to perform oncological mastectomies with sedation. It is important to remember that breast augmentation surgery is associated not only with pectoral muscle spasm, but also with an additional pain factor, namely, the insertion of retropectoral prostheses. This entails the creation of a “pocket” to hold the prosthesis by detaching the muscle from the costal wall, which is painful. In addition, the anterior branches of the intercostals that innervate this area are not anaesthetised, and the innervation supplied by the small branches of the supraclavicular nerves coming from the superficial cervical plexus must also be taken into account.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">10</span></a></p><p id="par0175" class="elsevierStylePara elsevierViewall">Neither the nerve block nor the drugs administered were associated with any complications in any of the study patients.

Despite this limitation, the descriptive data support the efficacy of this technique beyond the immediate postoperative period, since they show better haemodynamic stability and decreased consumption of intraoperative fentanyl and rocuronium.
