Neurodevelopmental outcome at 5 years of age after general anaesthesia or awake-regional anaesthesia in infancy (GAS)trial

Background: In laboratory animals, exposure to most general anaesthetics leads to neurotoxicity manifested by neuronal cell death and abnormal behaviour and cognition. Some large human cohort studies have shown an association between general anaesthesia at a young age and subsequent neurodevelopmental deficits, but these studies are prone to bias. Others have found no evidence for an association. We aimed to establish whether general anaesthesia in early infancy affects neurodevelopmental outcomes. Methods: In this international, assessor-masked, equivalence, randomised, controlled trial conducted at 28 hospitals in Australia, Italy, the USA, the UK, Canada, the Netherlands, and New Zealand, we recruited infants of less than 60 weeks' postmenstrual age who were born at more than 26 weeks

Perioperative management of infant inguinal hernia surgery; a review of the recent literature

OnlinePublInguinal hernia surgery is one of the most common electively performed surgeries in infants. The common nature of inguinal hernia combined with the high-risk population involving a predominance of preterm infants makes this a particular area of interest for those concerned with their perioperative care. Despite a large volume of literature in the area of infant inguinal hernia surgery, there remains much debate amongst anesthetists, surgeons and neonatologists regarding the optimal perioperative management of these patients. The questions asked by clinicians include; when should the surgery occur, how should the surgery be performed (open or laparoscopic), how should the anesthesia be conducted, including regional versus general anesthesia and airway devices used, and what impact does anesthesia choice have on the developing brain? There is a paucity of evidence in the literature on the concerns, priorities or goals of the parents or caregivers but clearly their opinions do and should matter. In this article we review the current clinical surgical and anesthesia practice and evidence for infants undergoing inguinal hernia surgery to help clinicians answer these questions.Fiona Taverner, Prakash Krishnan, Robert Baird, Britta S. von Ungern-Sternber

Allergy alerts - The incidence of parentally reported allergies in children presenting for general anesthesia

Background and aim Pediatric patients increasingly report allergies, including allergies to food and medications. We sought to determine the incidence and, nature of parent‐reported allergies in children presenting for surgery and its significance for anesthetists. Methods We prospectively collected data on admissions through our surgical admission unit over a 2‐month period at a pediatric tertiary care teaching hospital. Data collected included patient demographics, history of atopy, with more comprehensive information collected if an allergy was reported. A clinical immunologist and an anesthetist reviewed the documentation of all patients reporting an allergy. Results We reviewed 1001 pediatric patients, 158 (15.8%) patients with parent‐reported allergies; to medications/drugs (n = 73), food (n = 66), environmental allergens (dust/grasses, n = 35), tapes/dressings (n = 27), latex (n = 4), and venom (eg, bee, wasp, n = 9). Forty‐one patients reported antibiotic allergies, with Beta‐lactam antibiotics being the most common, with the majority presenting with rash alone (57%). Ten patients reported allergies to nonsteroidal anti‐inflammatory drugs and eight to opioids. Twenty‐four patients reported egg and/or peanut allergy. Only 3/1001 (0.3%) patients were deemed to have evidence of likely IgE‐mediated drug allergy. Of the reported allergies, only 60 (38.2%) had been investigated prior, most likely to be followed up were food (53%) and environmental allergies (44.4%). Only 4/73 (5.5%) reported medication allergies had further follow‐up. Just four patients (0.4% of the entire cohort) had drug sensitivities/allergies that were likely to majorly alter anesthesia practice. Conclusion Only the minority of parent‐reported allergies in pediatric surgical patients were specialist confirmed and likely to be clinically relevant. Self‐reported food allergy is commonly specialist verified whereas reactions to medications were generally not. Over‐reporting of allergies is increasingly common and limits clinician choice of medications. Better education of patients and their families and more timely verification or dismissal of parent‐reported reactions is urgently needed

The role of skin testing and extended antibiotic courses in assessment of children with penicillin allergy: An Australian experience

Aim To determine if skin testing (ST) in addition to extended oral provocation challenge (OPC) is necessary for beta‐lactam allergy verification in an Australian paediatric population. Methods This was a retrospective study (176 children) that undertook assessments for beta‐lactam allergy from 2006 to 2015 at a tertiary paediatric hospital. Patients either underwent direct OPC without ST or ST plus challenge if ST was negative. Results The analysis included children with a history of varying rash types/severity as well as angioedema and reported anaphylaxis. A direct OPC was undertaken in 73 children. Three children reacted with one anaphylaxis. A total of 103 children underwent ST, with 13 children (12.6%) reacting. Of the 90 who subsequently proceeded to OPC, 4 reacted. A total of 132 children were given an extended oral course of the culprit antibiotic, to which 6 children reacted. Conclusions A direct OPC with the culprit drug in Australian children can be safely performed, avoiding resource‐intensive and painful ST. Our data demonstrate that a prior history of anaphylaxis does not necessarily predict IgE‐mediated allergy, as detected by positive immediate ST or reactions to oral challenge. Such history should not detract from efforts to assess these children for antibiotic allergy. We suggest that extended courses of at least 5 days are important in paediatric antibiotic de‐labelling as six children (4.5% of those who were prescribed the extended course) reacted in our study and even developed symptoms late in the extended course, from days 2 to 6
