Overview

This study aimed to compare the effectiveness of preoperative PECS I block and intraoperative local anesthetic infiltration in managing postoperative pain following breast augmentation surgery. The primary focus was to evaluate their impact on postoperative pain levels, perioperative remifentanil and postoperative opioid consumption and opioid-related side effects during the early recovery period.

Breast augmentation is one of the most performed procedures in aesthetic surgery worldwide.These techniques, which involve muscle dissection and manipulation, tend to be more painful compared to subglandular and subfascial placements. Thus, managing postoperative pain effectively becomes a critical aspect of patient recovery and satisfaction. To address postoperative pain in breast augmentation, various techniques, including regional anesthesia such as pectoral nerve blocks, local anesthetic infiltration, and pocket irrigation, are employed. This study aimed to compare the effectiveness of preoperative PECS I block and intraoperative local anesthetic infiltration in managing postoperative pain following breast augmentation surgery. The primary focus was to evaluate their impact on postoperative pain levels, perioperative remifentanil and postoperative opioid consumption and opioid-related side effects during the early recovery period. This prospective, double-blind, split-body design study was conducted at Yeditepe University Faculty of Medicine, Plastic, Reconstructive, and Aesthetic Surgery Department, in collaboration with the Anesthesiology and Reanimation Department. The anesthesia induction and PECS I blocks for the right breasts were performed by the same anesthesiologist in all patients (O.K.). Breast augmentation surgeries and local anesthetic infiltrations for the left breasts were performed by the same plastic surgeon (M.E.). Postoperative pain assessments were conducted by a different anesthesiologist who was blinded to the study design. Postoperative pain was assessed using the Numeric Rating Scale (NRS), ranging from "0 = no pain" to "10 = unbearable pain." Pain assessments were performed every 30 minutes for the first 2 hours, every 2 hours between 2 and 6 hours, and at the 24ᵗʰ hour postoperatively.

Interventions

PECS I BlockPROCEDURE

The PECS I block is a regional anesthesia technique performed preoperatively under ultrasound guidance. It involves the injection of 10 mL of 0.5% bupivacaine between the pectoralis major and pectoralis minor muscles to block the medial and lateral pectoral nerves. This procedure targets the right breast in the study to reduce postoperative pain and is compared to local anesthetic infiltration.

Local Anesthetic InfiltrationPROCEDURE

Local anesthetic infiltration involves the intraoperative administration of 10 mL of 0.5% bupivacaine under direct visualization into the pectoralis major muscle prior to muscle transection. This procedure targets the left breast in the study for pain management and is compared to the PECS I block.

Outcomes

Primary Outcomes

Postoperative Pain Intensity

The level of postoperative pain in each breast region (right vs. left) measured using the Numeric Rating Scale (NRS). Pain scores will be recorded at specific intervals: every 30 minutes for the first 2 hours, every 2 hours from 2 to 6 hours, at the 24th hour, on the 5th postoperative day, and at the 3rd month. The primary focus is the pain intensity within the first 6 hours postoperatively.

Time frame: Up to 6 hours post-surgery.

Secondary Outcomes

Opioid Consumption

Total tramadol consumption recorded within the first 6 hours and the first 24 hours postoperatively. This includes the amount administered via patient-controlled analgesia (PCA) and any additional doses required.

Time frame: Up to 24 hours post-surgery.

Opioid-Related Side Effects

Incidence of opioid-related side effects such as nausea, vomiting, constipation, and respiratory depression. These will be monitored and recorded for each participant during the postoperative hospital stay

Time frame: Up to 24 hours post-surgery

Chronic Pain Assessment

Presence of chronic pain in the breast region assessed using the Numeric Rating Scale (NRS) at the 3rd-month follow-up

Time frame: At 3 months post-surgery

Postoperative Complications

Incidence of complications such as wound dehiscence, hematoma, infection, implant rupture, or sensory changes in the nipple. All complications will be recorded during routine follow-ups.

Time frame: Up to 3 months post-surgery
