ReviewCurrent status of the combined spinal-epidural technique in obstetrics and surgery.
Epidural and spinal blocks are well-accepted neuraxial techniques but both have several disadvantages. Combined spinal-epidural (CSE) can combine the best features of both techniques and reduce or eliminate these disadvantages. It provides the rapidity, density, and reliability of subarachnoid block with the flexibility of catheter epidural technique to extend the duration of anesthesia/analgesia (and to improve spinal block). ⋯ CSE is also used for cesarean delivery. The main purpose is to decrease the spinal dose so that spinal-induced hypotension can be reduced. However, reducing the spinal dose requires an epidural catheter to avoid intra-operative pain when surgery is prolonged.

Health-Related Quality of Life following Robotic-Assisted or Video-Assisted Lobectomy in Patients with Non-Small-Cell Lung Cancer: Results from The RVlob Randomized Clinical Trial.
Robot-assisted lobectomy (RAL) is increasingly used as an alternative to video-assisted lobectomy (VAL) for resectable non-small cell lung cancer (NSCLC). However, there is little evidence of any difference in postoperative health-related quality of life (HRQoL) between these two approaches. ⋯ gov.

ReviewManagement of adverse effects of intrathecal opioids in acute pain.
Intrathecal opioids have been used for several decades in different clinical settings. They are easy to administer and provide many benefits in clinical practice, such as better quality of spinal anaesthesia, prolonged postoperative analgesia, decreased postoperative analgesic requirements and early mobilisation. ⋯ In contrast, intrathecal hydrophilic opioids may have potentially serious adverse effects, the most feared of which is respiratory depression. In this review, we will focus on the contemporary evidence regarding intrathecal hydrophilic opioids and present their adverse effects and how to manage them.

Fentanyl exhibits interindividual variability in its dose requirement due to various nongenetic and genetic factors such as single nucleotide polymorphisms (SNPs). This study aims to develop and cross-validate robust predictive models for postoperative fentanyl analgesic requirement and other related outcomes in patients undergoing major breast surgery. Data regarding genotypes of 10 candidate SNPs, cold pain test (CPT) scores, pupillary response to fentanyl (PRF), and other common clinical characteristics were recorded from 257 patients undergoing major breast surgery. ⋯ The variant genotype of CTSG (rs2070697), higher intraoperative fentanyl use, and higher CPT scores were associated with significantly lower TFA. The predictive models for 24-hour postoperative fentanyl requirement, pain scores, and TFA had R-squared values of 0.313 (SVM-Linear), 0.434 (SVM-Linear), and 0.532 (RF), respectively. We have developed and cross-validated predictive models for 24-hour postoperative fentanyl requirement, 24-hour postoperative pain scores, and TFA with satisfactory performance characteristics and incorporated them in a novel web application.

ReviewPerioperative and anesthetic considerations for the management of neuromodulation systems.
The use of neuromodulation systems is increasing for the treatment of various pathologies ranging from movement disorders to urinary incontinence to chronic pain syndromes. While the type of neuromodulation devices varies, they are largely categorized as intracranial (eg, deep brain stimulation), neuraxial (eg, spinal cord stimulation, dorsal root ganglion stimulation, and intrathecal drug delivery systems), or peripheral (eg, sacral nerve stimulation and peripheral nerve stimulation) systems. Given the increasing prevalence of these systems in the overall population, it is important for anesthesiologists, surgeons, and the perioperative healthcare team to familiarize themselves with these systems and their unique perioperative considerations. In this review, we explore and highlight the various neuromodulation systems, their general perioperative considerations, and notable special circumstances for perioperative management.
