ReviewA systematic review and quantitative analysis of neurocognitive outcomes in children with four chronic illnesses.
Concern has been expressed that infants and children exposed to uneventful surgery and anesthesia may incur neurological injury that becomes manifest in poor scholastic performance or future learning difficulties. A recent meta-analysis of seven clinical studies examined the relationship between learning or behavior difficulties and pediatric exposure to anesthesia/surgery and reported an odds ratio of 1.4; however, the level of association and causal factors remain unclear. The purpose of our study is to provide context to the pediatric anesthesia neurotoxicity question by reviewing the evidence linking four childhood illnesses with neurocognitive development. In the present review, we have sought to quantify the magnitude of the impact of chronic illness on neurocognitive development through a systematic review of publications that report the developmental trajectory of patients with four childhood diseases: cystic fibrosis (CF), hemophilia A, end-stage renal disease (ESRD) and end-stage liver disease (ESLD). ⋯ Overall, the results suggest that the burden of chronic childhood illness, by itself, does not impair cognitive development in children with hemophilia A and CF. Children with ESRD and ESLD, despite optimal management, show a mild cognitive deficit compared with the population norm. Given the impact of these four specific chronic illnesses on neurocognitive outcome in children and the improvement in IQ post-transplant in both ESRD and ESLD, the results suggest that the effect of an uncontrolled confounding illness on neurocognitive development is small.

Randomized Controlled Trial Comparative StudyEfficacy of subtenon block in infants - a comparison with intravenous fentanyl for perioperative analgesia in infantile cataract surgery.
General anesthesia with opioids provides good perioperative analgesia in infantile ocular surgeries but is associated with the risk of respiratory depression and postoperative emesis. This study aimed to assess the effectiveness of subtenon block for providing perioperative analgesia in infants undergoing cataract surgeries. ⋯ Subtenon block is an effective superior technique for postoperative analgesia compared to intravenous fentanyl in infants undergoing cataract surgery.

Mild hypothermia increases pulmonary anti-inflammatory response during protective mechanical ventilation in a piglet model of acute lung injury.
The effects of mild hypothermia (HT) on acute lung injury (ALI) are unknown in species with metabolic rate similar to that of humans, receiving protective mechanical ventilation (MV). We hypothesized that mild hypothermia would attenuate pulmonary and systemic inflammatory responses in piglets with ALI managed with a protective MV. ⋯ Mild hypothermia induced a local anti-inflammatory response in the lungs, without affecting lung function or coagulation, in this piglet model of ALI. The HT group had lower cardiac output without signs of global dysoxia, suggesting an adaptation to the decrease in oxygen uptake and delivery. Studies are needed to determine the therapeutic role of HT in ALI.

Features of lateral cephalograms associated with difficult laryngoscopy in Japanese children undergoing oral and maxillofacial surgery.
Difficult laryngoscopy and tracheal intubation are occasionally encountered in children with congenital anomalies or micrognathia. However, no study has elucidated anatomical etiology in relation to craniofacial development. ⋯ Difficult laryngoscopy and tracheal intubation are expected in children aged <4 years with lower-positioned hyoid bone caused by caudal larynx as well as undeveloped maxilla and mandible, and in those aged ≥4 years with increased inclination of the mandible as well as undeveloped mandible.

Minimum alveolar concentration of desflurane with caudal analgesia for laryngeal mask airway removal in anesthetized children.
Regional blocks have been shown to decrease the requirement of anesthetic agents. This study was conducted to determine the optimal endtidal concentrations of desflurane for removal of Laryngeal mask airway in children in presence of caudal block. ⋯ Laryngeal mask airway can be successfully removed in 50% of anesthetized children without coughing, moving, or any other airway complications at an endtidal desflurane concentration of 3.4% in the presence of caudal analgesia.
