Background And Aims: Intraoperative regional analgesia and enhanced recovery are standard care models aimed at reducing perioperative opioid use following spine surgeries. This study aimed to examine the analgesic effect of retrolaminar block in promoting recovery and pain relief after posterior lumbar discectomy.
Methods: The patients undergoing elective posterior lumbar discectomy were randomised into the retrolaminar group (n = 36) (received an intra-operative bilateral retrolaminar block with 15 mL of bupivacaine 0.25%, 2 mL (8 mg) of dexamethasone, and 2 mL of magnesium sulphate 10% (200 mg) on each side) and control group (n = 36) (received standard general anaesthesia). Primary outcomes were recovery time (time from isoflurane discontinuation to the first response to verbal command) and time to discharge (time from admission to the post-anaesthesia care unit (PACU) to discharge from the PACU, when Aldrete score was ≥9). values < 0.05 were considered statistically significant.
Results: The extubation, recovery, and discharge times were significantly shorter in the retrolaminar group compared to the control group ( < 0.001). Postoperative pain scores were significantly lower in the retrolaminar group for up to 8 h compared to only 2 h in the control group ( < 0.001). The time to first administration of ketorolac post-operatively was significantly longer in the retrolaminar group compared to the control group ( < 0.001). The total consumption of ketorolac post-operatively was significantly reduced in the retrolaminar group compared to the control group ( < 0.001).
Conclusion: Intra-operative retrolaminar block is an easy and effective opioid-free regional anaesthesia technique that improves recovery after posterior lumbar discectomy.

Article Synopsis
- This study investigates the effectiveness of three types of nerve blocks (ESPB, RLB, and TPVB) for managing pain after thoracic surgery.
- The research involved 76 patients and measured pain levels using a Numeric Rating Scale over 24 hours, along with other factors like opioid use and recovery.
- Results showed that ESPB and RLB were just as effective as TPVB in controlling pain without significant differences in side effects or recovery outcomes.

Article Synopsis
- Adjuvant therapy, specifically CEV chemotherapy, is crucial for treating high-risk unilateral retinoblastoma, but there hasn't been sufficient comparison between administering 3 vs. 6 cycles of this treatment.
- A randomized trial involving 187 patients aimed to determine if 3 cycles of CEV chemotherapy is as effective as 6 cycles in terms of disease-free survival after enucleation.
- The results showed that the 3-cycle regimen had comparable disease-free survival rates and was associated with fewer adverse events and lower costs, suggesting it could be a more efficient treatment option.

Background And Aims: Moderate-to-severe intensity pain is reported on the first day following lower abdominal surgery. No study has compared transversus abdominis plane (TAP) block with retrolaminar block (RLB) in laparoscopic inguinal hernia surgery for postoperative pain relief.
Material And Methods: In this prospective, randomized trial, 42 patients of American Society of Anesthesiologists (ASA) physical status I and II, aged 18-65 s, and having a BMI <40 kgm received TAP or RLB following laparoscopic inguinal hernia surgery.

Purpose: Spinal decompression surgery causes severe pain. Retrolaminar block (RLB) is block, which is done by infiltration of local anesthetic to block spinal nerves between the lamina and superior costotransversospinalis muscle. The primary aim of this study is to evaluate the effectiveness of RLB on postoperative analgesia in patients undergoing spinal surgery.

Background: In daily surgical practice, inguinal hernioplasty is a frequent procedure that is frequently accompanied by severe postoperative pain. Multiple regional blocks have been described for analgesia after such operations. Retrolaminar block (RLB) is a paravertebral block (PVB) variant that provides excellent analgesia and reduces the risk of complications.
