Regional Anesthesia for Vascular Surgery and Pain Management.

Patients undergoing vascular surgery tend to have significant systemic comorbidities. Vascular surgery itself is also associated with greater cardiac morbidity and overall mortality than other types of noncardiac surgery. Regional anesthesia is amenable as the primary anesthetic technique for vascular surgery or as an adjunct to general anesthesia.

Liposomal Bupivacaine Plus Bupivacaine Versus Ropivacaine Plus Dexamethasone Brachial Plexus Blockade for Arthroscopic Rotator Cuff Repair: An Unblinded Randomized Controlled Trial.

Unlabelled: Brachial plexus blockade is utilized for pain control during arthroscopic rotator cuff repair. The purpose of the present study was to evaluate brachial plexus blockade with liposomal bupivacaine plus bupivacaine (LB+B) as compared with ropivacaine plus dexamethasone (R+D) for arthroscopic rotator cuff repair. Our hypothesis was that the use of LB+B would result in lower pain scores and opioid consumption as compared with R+D.

Regional analgesia for cardiac surgery.

Purpose Of Review: Regional anesthesia is gaining attention as a valuable component of multimodal, opioid-sparing analgesia in cardiac surgery, where improving the patient's quality of recovery while minimizing the harms of opioid administration are key points of emphasis in perioperative care. This review serves as an outline of recent advancements in a variety of applications of regional analgesia for cardiac surgery.

Recent Findings: Growing interest in regional analgesia, particularly the use of newer "chest wall blocks", has led to accumulating evidence for the efficacy of multiple regional techniques in cardiac surgery.

The Effect of the No Pain Labor & Delivery-Global Health Initiative on Cesarean Delivery and Neonatal Outcomes in China: An Interrupted Time-Series Analysis.

Background: The proportion of live births by cesarean delivery (CD) in China is significant, with some, particularly rural, provinces reporting up to 62.5%. The No Pain Labor & Delivery-Global Health Initiative (NPLD-GHI) was established to improve obstetric and neonatal outcomes in China, including through a reduction of CD through educational efforts.

Depth of sedation as an interventional target to reduce postoperative delirium: mortality and functional outcomes of the Strategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients randomised clinical trial.

Background: The Strategy to Reduce the Incidence of Postoperative Delirium in the Elderly trial tested the hypothesis that limiting sedation during spinal anaesthesia decreases in-hospital postoperative delirium after hip fracture repair. This manuscript reports the secondary outcomes of this trial, including mortality and function.

Methods: Two hundred patients (≥65 yr) undergoing hip fracture repair with spinal anaesthesia were randomised to heavier [modified Observer's Assessment of Alertness/Sedation score (OAA/S) 0-2] or lighter (OAA/S 3-5) sedation, and were assessed for postoperative delirium.

Effect of Depth of Sedation in Older Patients Undergoing Hip Fracture Repair on Postoperative Delirium: The STRIDE Randomized Clinical Trial.

Importance: Postoperative delirium is the most common complication following major surgery in older patients. Intraoperative sedation levels are a possible modifiable risk factor for postoperative delirium.

Objective: To determine whether limiting sedation levels during spinal anesthesia reduces incident delirium overall.

Seldinger technique for nasal intubation: a case series.

Nasotracheal intubation can be both challenging and traumatic, especially in cases of atypical anatomy. We present a series of 3 such cases in which an endotracheal tube introducer (bougie) was used to facilitate successful, atraumatic, nasotracheal intubation via Seldinger technique. The technique described can guide a nasotracheal tube through narrow nasal passages, small pharyngeal spaces, and past acute laryngeal approach angles, all without transoral manipulation of the tube.

No Pain Labor & Delivery: A Global Health Initiative's Impact on Clinical Outcomes in China.

The availability of labor analgesia is highly variable in the People's Republic of China. There are widespread misconceptions, by both parturients and health care providers, that labor epidural analgesia is harmful to mother and baby. Meanwhile, China has one of the highest cesarean delivery rates in the world, exceeding 50%.

The role of perioperative chewing gum on gastric fluid volume and gastric pH: a meta-analysis.

Study Objective: To determine if preoperative gum chewing affects gastric pH and gastric fluid volume.

Design: Systematic review and meta-analysis.

Methods: Data sources included Cochrane, PubMed, and EMBASE databases from inception to June 2012 and reference lists of known relevant articles without language restriction.

Evaluation of epidural and peripheral nerve catheter heating during magnetic resonance imaging.

Background: Many epidural and peripheral nerve catheters contain conducting wire that could heat during magnetic resonance imaging (MRI), requiring removal for scanning.

Methods: We tested 2 each of 6 brands of regional analgesia catheters (from Arrow International [Reading, Pennsylvania], B. Braun Medical Inc [Bethlehem, Pennsylvania], and Smiths Medical/Portex [Keene, New Hampshire]) for exposure to clinical 1.

Improved residents' knowledge after an advanced regional anesthesia education program.

Background: Although residents in anesthesia are confident in performing neuraxial anesthesia, many are not confident in performing peripheral nerve blocks. The purpose of this study was to evaluate the effectiveness of a structured regional anesthesia teaching program in a large academic medical center.

Methods: Residents participated in regional anesthesia didactics that took place in a unique resident education program scheduled during two fully protected teaching days a month.

Curriculum development for an advanced regional anesthesia education program: one institution's experience from apprenticeship to comprehensive teaching.

Results of recent attitude survey studies suggest that most practicing physicians are inadequately treating postoperative pain. Residents in anesthesia are confident in performing lumbar epidural and spinal anesthesia, but many are not confident in performing the blocks with which they have the least exposure. Changes need to be made in the training processes to a comprehensive model that prepares residents to perform a wider array of blocks in postgraduate practice.

Special anesthetic consideration for the patient with a fragility fracture.

In this article, an overview is presented of perioperative management of the patient with a fragility fracture, including preoperative risk stratification and optimization, anesthesia risks, anesthesia options, and postoperative pain management. Issues of preoperative evaluation that are of concern for the anesthesiologist because of their direct effect on intraoperative care are discussed. A team interdisciplinary approach and good communication between specialties involved in care of elderly surgical patients is important for optimal patient outcomes and to avoid perioperative complications.

Analgesic efficacy of continuous intravenous magnesium infusion as an adjuvant to morphine for postoperative analgesia: a systematic review and meta-analysis.

Background: The efficacy of perioperative intravenous magnesium administration on postoperative opioid use, opioid-related side effects (e.g., nausea and vomiting) and pain are uncertain, as randomized controlled trials on this topic have reported disparate results.

Analgesic efficacy of intravenous naloxone for the treatment of postoperative pruritus: a meta-analysis.

Objectives: Pruritus may be a significant problem for patients in the postoperative period. There are many options for the treatment of pruritus including intravenous (IV) naloxone. However, it is not clear whether the use of IV naloxone may also affect analgesia or other opioid-related side effects.

Analgesic efficacy of ultrasound-guided regional anesthesia: a meta-analysis.

Study Objective: To determine if the use of ultrasound guidance (vs non-ultrasound techniques) improves the success rate of nerve blocks.

Design: Meta-analysis of randomized controlled trials (RCTs) in the published literature.

Setting: University medical center.
