Article Abstract
Purpose: Research indicates that the dural puncture epidural (DPE) technique offers quicker analgesia onset compared to the conventional epidural (EP) technique. Programmed intermittent epidural bolus (PIEB) is superior to continuous epidural infusion (CEI) for maintaining labor analgesia, providing better pain relief and less motor block. Few studies have explored if combining DPE with the PIEB offers additional benefits in analgesia onset, maintenance, local anesthetic consumption, and side effects compared to DPE with EP. We hypothesized that DPE, when combined with PIEB, not only speeds up analgesia onset but also improves neuraxial analgesia maintenance over EP.
Patients And Methods: A total of 126 term nulliparous women with singleton pregnancies with a VAS pain score >50 mm and cervical dilation <5 cm were randomized to receive EP+PIEB or DPE+PIEB for labor analgesia, initiated with 15 mL of 0.0625% ropivacaine with 0.4 µg/mL of sufentanil using the EP or DPE technique (using 25-gauge Whitacre needle) technique and both maintained with the same solution for PIEB (fixed volume 10 mL, intervals 45 minutes, lockout interval 15 minutes) with labor analgesia. The primary outcome was time to achieving adequate analgesia, defined as a VAS pain score ≤30 mm. Secondary outcomes included pain scores, motor blockade, obstetric and neonatal outcomes, and satisfaction with analgesia.
Results: Adequate analgesia was achieved faster in the DPE+PIEB group than in the EP+PIEB group (hazard ratio 2.409; 95% CI 1.670 to 3.474, <0.001). The median time (interquartile range) to VAS pain score ≤30 mm was 10 (7 to 13) minutes for the DPE+PIEB group and 15 (11 to 19) minutes for the EP+PIEB group (<0.001). No differences in any of the secondary outcomes between the two groups were observed.
Conclusion: DPE with PIEB accelerated onset time but did not improve maintenance of neuraxial labor analgesia over DPE with EP.

Neuraxial anesthesia and pain management for cesarean delivery.
Am J Obstet Gynecol

Department of Anesthesiology, Perioperative and Pain Medicine, Stanford University, Palo Alto, CA.
Optimal neuraxial anesthesia for cesarean delivery requires a thorough understanding of patient, obstetrical, surgical, and anesthesia-related factors which can impact pain during and after cesarean delivery. While not all cesarean deliveries are the same from an obstetrical standpoint, not all anesthetics provide the same degree of anesthetic blockade and postcesarean analgesia; therefore, context is crucial to provide patients with a safe and pain-free experience. Communication between obstetrical and anesthesia teams is key to ensure that the anesthetic approach is tailored to the clinical scenario, particularly if emergency cesarean delivery is needed, and follows best practices for cesarean delivery anesthesia.

Background And Aims: Regional anaesthesia for clavicle surgery focuses on site-specific nerve blocks to minimise the drug volume, prevent unnecessary nerve block, and reduce complications. This study aimed to compare the effectiveness and dynamics of selectively blocking supraclavicular (SC) nerves and upper trunk (UT) of the brachial plexus (SCUT block) with clavipectoral fascial plane (CPF) block as a site-specific regional anaesthesia strategy for clavicle surgery.
Methods: In this single-centre, double-blinded, randomised study, 50 patients undergoing clavicle surgeries were given either SCUT block or CPF block with SC nerve block under ultrasound guidance with 20 mL of 0.

Background: The combination of short- and long-acting local anaesthetics is traditionally associated with reduced block duration, though evidence remains inconsistent.
Objectives: To investigate the effects of a fixed or reduced dose of a long-acting local anaesthetic (ropivacaine) mixed with a short-acting agent (lidocaine-epinephrine) on duration of analgesia and sensory onset time in lateral infraclavicular blocks.
Design: Randomised, blinded, active-controlled superiority trial.

Background: Dexamethasone is commonly used as an adjuvant to prolong analgesia in peripheral nerve blocks. However, there are a few studies available regarding its use in combination with mixed local anesthetics.
Aim: This study investigated the effect of adding perineural dexamethasone to an infraclavicular block containing a medium- and long-acting local anesthetic mixture on the time to the first analgesia request (sensory block duration) as the primary outcome, as well as sensory and motor block onset times, motor block duration, postoperative analgesic use, and the development of long-term chronic pain as secondary outcomes.
