Background and Aims Retrolaminar block is a thoracic truncal block, that produces analgesia for thoracic and abdominal wall surgeries. There is limited knowledge about the actual distribution of retrolaminar plane injectates. This series aimed to determine analgesic efficacy by measuring perioperative analgesic consumption and pain scores.
Methods After informed consent, RLB was performed in a sitting position at the level of T4 with an injectate of 0.25% Ropivacaine and 1% lignocaine with adrenaline (30 ml). Once the patient awakened, the pain was assessed by an 11-point Numeric Rating Scale (MRS) score at 1, 2, 4, 6, 12, and 24 hours post-surgery. All the patients were connected to a PCA device so that they could self-administer fentanyl boluses. At 24 hours post-surgery the total analgesic consumption was noted and the Patient satisfaction score (PSS) was noted on a 5-point Likert scale.
Results Fifteen females with a mean(S.D.) age of 45.8(14.6) yrs, weight 60.7(13.6) kg, height 156.3(6.5) cm and BMI 25(5.5) kg/m2. The average duration of block performance was 2.43 minutes. The mean(S.D.) intraoperative and total 24-hour fentanyl requirement was 25.3(39.4) mcg and 35(40) mcg. Nine out of 15 patients did not require intraoperative fentanyl. The mean NRS in 24 hours was never more than 2.5 (figure 1). The average duration of the block lasted for 14.9(10.4) hours. The average patient satisfaction score was good.
Conclusions Retrolaminar block can be used as an effective block for breast surgery with lower perioperative pain scores, lower total opioid consumption, and good patient satisfaction scores.
