Randomized Controlled Trial Multicenter Study
Ultrasound guided pediatric caudal dose: a two-center randomized controlled trial.
The drug volume to be used in caudal in pediatric patients has remained an unmet issue since long. We determined the minimum drug volume required to reach T10 level in pediatric patients using ultrasonography and compared it with the already established volume by Armitage formula. ⋯ A volume of 0.7 ml/kg of local anaesthetic in pediatric caudal block is sufficient to achieve a target of T10 level for infraumblical surgeries.

Cannabinoids and General Anesthetics: Revisiting Molecular Mechanisms of Their Pharmacological Interactions.
Cannabis has been used for recreation and medical purposes for more than a millennium across the world; however, its use's consequences remain poorly understood. Although a growing number of surgical patients are regular cannabis consumers, little is known regarding the pharmacological interactions between cannabis and general anesthetics; consequently, there is not a solid consensus among anesthesiologists on the perioperative management of these patients. The existing evidence about the molecular mechanisms underlying pharmacological interactions between cannabinoids and anesthetic agents, both in animal models and in humans, shows divergent results. ⋯ Animal studies have reported that cannabinoids enhance the analgesic effect of opioids due to a synergistic interaction of the endogenous cannabinoid system (ECS) with the endogenous opioid system (EOS) at the spinal cord level and in the central nervous system. However, human data reveals that cannabis users show higher scores of postoperative pain intensity as well as increased requirements of opioid medication for analgesia. This review aims to improve understanding of the molecular mechanisms and pharmacological interactions between cannabis and anesthetic drugs and the clinical outcomes that occur when these substances are used together.

Randomized Controlled TrialEffect of anterior quadratus lumborum block with ropivacaine on the immune response after laparoscopic surgery in colon cancer: a substudy of a randomized clinical trial.
Surgery induces a temporal change in the immune system, which might be modified by regional anesthesia. Applying a bilateral preoperative anterior quadratus lumborum block has proven to be a safe and effective technique in pain management after abdominal and retroperitoneal surgery, but the effect on the immune response is not thoroughly investigated. ⋯ Our study provides evidence that administration of bilateral anterior quadratus lumborum nerve block as a part of a multimodal analgesic regimen in an enhanced recovery after surgery for laparoscopic hemicolectomy in this cohort does not alter the systemic immune response. Trial registration number NCT03570541.

Observational StudySerum Levels of Bupivacaine After Bilateral Ultrasound-Guided Deep Parasternal Intercostal Plane Block in Cardiac Surgery with Median Sternotomy.
To evaluate systemic levels of bupivacaine after bilateral ultrasound-guided deep parasternal intercostal plan (PIP) block in cardiac surgical patients undergoing median sternotomy. ⋯ Bilateral PIP placed at the end of cardiac surgery resulted in low systemic bupivacaine levels. The inclusion of additives shortened Tmax without improving outcome.

Intravenous Versus Peribulbar Dexmedetomidine as an Adjunct to Local Anesthetics in Strabismus Surgery: A Randomized, Double-blinded Clinical Trial.
Dexmedetomidine has not been adequately studied as an adjuvant to peribulbar anesthesia in strabismus surgery. ⋯ Peribulbar dexmedetomidine outperforms intravenous dexmedetomidine in terms of postoperative analgesia and motor block duration when used as an adjunct to peribulbar anesthesia for strabismus surgery. However, the intravenous group had significantly shorter surgical times.
