Impact of transversus abdominis plane blocks versus non-steroidal anti-inflammatory on post-operative opioid use in ERAS ovarian cancer surgery.
Treatment of ovarian cancer often requires extensive surgical resection. The transversus abdominis plane (TAP) block has been utilized in benign gynecologic surgery to decrease post-operative pain and opioid use. We hypothesized that TAP blocks would decrease total opioid use in the first 24 hours and decrease length of stay following staging and cytoreductive surgery for ovarian cancer compared with either no local anesthetic or local wound infiltration alone. ⋯ Post-operative administration of NSAIDs, but not TAP block, was associated with a decrease in post-operative opioid use and length of stay following surgery for ovarian cancer. Further investigation into alternative regional anesthetics for Enhanced Recovery after Surgery (ERAS) protocols is warranted.

Randomized Controlled Trial Comparative StudyA triple-blinded randomized trial comparing spinal morphine with posterior quadratus lumborum block after cesarean section.
What did they do?
Tamura and team randomised 176 elective CS patients to spinal anaesthesia with or without morphine, in addition to placebo or ultrasound-guided quadratus lumborum block (QLB).
And they found
Only intrathecal morphine significantly improved analgesia, not QLB whether performed with or without spinal morphine. Thus QLB probably does not improve analgesia further beyond current best practices.
Not so fast...
While this modest-sized RCT concluded that QLB did not improve pain after caesarean section, the conclusion is i) somewhat inconsistent with earlier studies that did show benefit, and ii) the adjuvant analgesic regime1 used may not be applicable to practice outside Japan.

The researchers administered the remaining 90 mcg fentanyl IV, along with droperidol 1.25 mg and acetaminophen/paracetamol 15mg/kg after baby delivery. An NSAID (diclofenac 50mg) was only provided when breakthrough pain was requested. ↩

Randomized Controlled Trial Comparative Study
Erector Spinae Plane Block vs Quadratus Lumborum Block for pediatric lower abdominal surgery: A double blinded, prospective, and randomized trial.
To evaluate and compare the analgesic effect of ultrasound-guided erector spinae plane (ESP) block with ultrasound-guided Quadratus Lumborum Block in pediatric lower abdominal surgeries. ⋯ This study shows that the ESPB provides similar postoperative analgesia to the QLB in pediatric patients undergoing lower abdominal surgery. Clinicians could decide according to their clinical experiences. CLINICAL TRIALS: https://clinicaltrials.gov/ct2/show/NCT03463382.

ReviewLocal anaesthetic techniques for post-caesarean delivery analgesia.
In this narrative review we summarise pertinent data from published studies investigating the use of local anaesthetic techniques as adjuncts for managing post-caesarean delivery pain. Based on currently available evidence, ultrasound-guided transversus abdominis plane (TAP), quadratus lumborum (QL) and ilio-inguinal and iliohypogastric (ILIH) blocks are preferable to landmark techniques. When intrathecal morphine is used for caesarean delivery analgesia, TAP blocks do not confer any additional benefit. ⋯ Quadratus lumborum and ILIH blocks show promising results but the data are limited, so recommendations for routine use cannot be made. In summary, evidence supports the use of local anaesthetic techniques for post-caesarean delivery pain but additional research is required to determine the optimum dosing regimens, and the potential role of liposomal local anaesthetics. Further studies are required to compare techniques and determine their role in conjunction with low-dose long-acting neuraxial opioids.
