ReviewIntrathecal drug delivery in the management of chronic pain.
Targeted intrathecal drug delivery (TIDD) has the objective of bringing the drug(s) close to the receptors influencing pain modulation, and thus reducing the dose and the side effects. Intrathecal drug delivery knew its real start with the development of permanent implantation of intrathecal and epidural catheters, combined with internal or external ports, reservoirs, and programmable pumps. TIDD is a valuable treatment for patients with cancer suffering refractory pain. ⋯ Only two drugs are approved by the US Food and Drug Administration for TIDD administration for chronic pain: morphine and ziconotide as monotherapy. In pain management, off-label use of medication and combination therapy is often reported. The specific action of the intrathecal drugs, the efficacy and safety, is described, as well as the modalities for trialing intrathecal drug delivery and the implantation methods.

ReviewContinuous spinal technique in surgery and obstetrics.
Continuous Spinal Anaesthesia (CSA) technique has all the advantages of single-shot spinal anaesthesia with the added benefit of prolonging the duration of anaesthesia. CSA has been used as a primary method of anaesthesia as an alternative to general anaesthesia in high-risk and elderly patients for various elective and emergency surgical procedures involving the abdomen, lower limbs, and vascular surgeries. ⋯ This article includes a description of CSA technique compared to other contemporary central neuraxial blocks. It also discusses the perioperative applications of CSA for different surgical and obstetrics procedures, advantages, disadvantages, complications, problems, and pointers on how to perform the technique safely.

ReviewPractical and societal implications of the potential anesthesia-induced neurotoxicity: The safetots perspective.
Key elements for safe and high-quality care in pediatric anesthesia are personal and institutional competence, perioperative maintenance of physiological homeostasis, prevention, prompt recognition, and appropriate treatment of critical situations as well as the reassurance of the parents and respecting the children's rights. Training in pediatric anesthesia should take place within the framework of harmonized curricular structures. ⋯ The Safetots.org initiative was established to emphasize the role of the conduct of anesthesia to prevent harm, promote quality in the perioperative period, and provide safe and high-quality clinical care. This initiative considers that the prevention of complications and other well-known risk factors of perioperative care, as well as the quality of anesthesia management, have a far more important impact on outcomes following anesthesia and surgery than anesthetic drugs themselves.

ReviewControversies in anesthesia-induced developmental neurotoxicity.
Advances in the field of pediatric anesthesiology have enabled the performance of complex and life-saving procedures with minimal patient discomfort. However, preclinical studies over the past two decades have been reporting substantial neurotoxic potential of general anesthetics in young brain, thus challenging the safety of these agents in pediatric anesthesiology practice. ⋯ The significant degree of anxiety and apprehension surrounding the uncertainty of long-term developmental outcomes following early exposure to anesthesia has prompted numerous studies around the world to investigate the putative mechanisms and translatability of preclinical findings regarding anesthesia-induced developmental neurotoxicity. Guided by the vast preclinical evidence, we aim to highlight relevant human findings presented in the currently available clinical literature.

ReviewNeuroprotective strategies in anesthesia-induced neurotoxicity.
Over the past 20 years, hundreds of preclinical studies of the developing central nervous system have been published concluding that the common γ-aminobutryic acid and N-methyl-d-aspartate binding anesthetic agents cause neuroapoptosis and other forms of neurodegeneration. Some clinical studies, including controlled trials, both prospective and ambidirectional in design, indicate an association between any exposure (single or multiple) to anesthesia and surgery at a young age, generally less than 3-4 years, and later behavioral and neurodevelopmental problems. A consideration of neuroprotective strategies is important, as scientists and clinicians alike ponder methods to potentially improve the neurodevelopmental outcomes of the millions of infants and children who undergo surgery and anesthesia annually around the world. This review will address plausible neuroprotective strategies and include alternative anesthetics, neuroprotective nonanesthetic drugs, and physiologic neuroprotection.
