Randomized Controlled Trial
Efficacy of premedication with intranasal dexmedetomidine on inhalational induction and postoperative emergence agitation in pediatric undergoing cataract surgery with sevoflurane.
This study aimed to test the hypothesis that premedication with a single dose of intranasal dexmedetomidine (DEX) could not only reduce preoperative anxiety but also minimize the emergence agitation in children undergoing cataract surgery with sevoflurane anesthesia. ⋯ Intranasal DEX (1 or 2 μg/kg) dose independently improves the incidences of mask acceptance and prevents the incidences of postoperative emergency agitation mainly from sevoflurane without delaying the emergency time or inducing severe adverse events.

Case Reports
Sevoflurane-associated torsade de pointes in a patient with congenital long QT syndrome genotype 2.
Although patients with congenital long QT syndrome (c-LQTS) are considered to be at high risk for anesthesia, few reports describe c-LQTS genotype-specific considerations for anesthesia. We describe a case of torsade de pointes (TdP) caused by sevoflurane in a patient with c-LQTS genotype 2 (LQT2). A 39-year-old woman diagnosed with c-LQTS was scheduled for an elective therapeutic abortion. ⋯ Postoperative studies revealed a mutation in the KCNH2 gene. Anesthesiologists should note that patients with LQT2 could be more susceptible to volatile anesthetics than are those with other major genotypes. Genotype-specific management of anesthesia may reduce the risk of developing TdP during the perioperative period.

The occurrence of lupus anticoagulant is associated with the hazard of developing an antiphospholipid syndrome, a severe prothrombotic condition which may particularly occur after major surgical trauma. This disease requires certain considerations regarding surgical strategy and anticoagulation management. We describe the perioperative management of a patient scheduled for elective aortic valve replacement and diagnosed for having antiphospholipid antibodies. The procedure was successfully performed using a minimally invasive approach via transapical aortic valve replacement and anticoagulation with the nonreversible short-acting direct thrombin Inhibitor bivalirudin.

Case Reports
Interventional and multimodal pain rehabilitation in a child with meralgia paresthetica.
Meralgia paresthetica is a chronic pain syndrome that is extremely rare in the pediatric population. It is manifested by hypesthesia or pain in the distribution of the lateral femoral cutaneous nerve (LFCN) and is typically caused by entrapment as the nerve passes deep to the inguinal ligament. This sensory mononeuropathy is rare in children and diagnosis is typically delayed, often leading to prolonged functional impairment and unnecessary medical testing. ⋯ A second LFCN block was performed with complete resolution of symptoms and restoration of function. The patient remains pain-free and has returned to walking, running, and competitive sports. The primary goal of pediatric chronic pain management, regardless of pain etiology, is early restoration of function to avoid prolonged absence from school, sports, or other productive activities and limit the psychological burden of chronic disease.

To investigate if the anesthetic/analgesic regimen is associated with the risk of reporting long-term chronic postmastectomy pain (CPMP). ⋯ In conclusion, our study confirms the high prevalence of CPMP, 4 to 9 years after surgery. Recall of preoperative pain, chemotherapy, and need for strong opioids in the postanesthesia care unit were all associated with the presence of chronic pain. Of the intraoperative analgesics/anesthetics studied, only use of halogenated agents was associated with a lower prevalence of CPMP.
